- PREFACE
-
-
-Having been associated with the printing telegraph for more than sixty
-years, I have felt the urge to write a résumé of the problems and the
-progress made during my time toward today’s wonderful achievements in
-the art of telegraphic communications.
-
-It is interesting to note that of all the old-time electric telegraph
-systems, it appears that only those using the Morse dot-dash code
-invented in 1837 and the permutation code devised by Gauss and Weber in
-1833 (now known everywhere as the Baudot code) have survived today.
-
-Samuel Morse’s code, which was modified somewhat in several letter code
-compositions to facilitate its use anywhere in the world, has become an
-audible, easily learned international language, loved by its users
-everywhere. It will no doubt continue to be used for some time to come,
-as long as we have our railroad telegraph operators, radio amateurs,
-police CW systems, certain branches of the Armed Forces, and any others
-who converse in dits and dahs.
-
-The permutation code has taken hold firmly, too. Its use of five pulses
-transmitted in varying combinations of on and off, or positive and
-negative, conditions has wide application in today’s printed
-communications systems. As in the Morse system, alphabets for the
-five-unit permutation code system have been modified as to letter code
-compositions for international correspondence. The permutation code uses
-the powers of two in progressively selecting a letter printing position.
-
-The binary code uses the same selective stops by yes or no designation
-in a system of counting by the powers of two. It is used where larger
-groups of yes or no positions are required, as in data processing and
-computer systems.
-
-This writing, then, is a bit of history that will put together the
-constructive developments that brought about the present era of the
-worldwide, telegraphically-transmitted printed word.
-
-I wish to acknowledge with great appreciation the informative material
-sent to me by my friends, both here and in foreign lands, who are
-associated with the telegraph industry.
-
-For assembling information we have gathered from various sources and for
-the most helpful assistance given me in writing this story, I also want
-to thank my secretary, Mrs. Doris Pompilio.

- A NEW ERA BEGINS

- CHAPTER 1
- Introduction
-
-
-It is a major effort today to keep pace with the rapid advances in the
-field of printed communications. Hardly a day passes that we do not read
-of a new development in equipment that is more complex, farther
-reaching, more rapid in operation....
-
-This electrical, or electronic, transmission and interchange of the
-printed word might be said to be an evolvement of the old printing
-telegraph systems. Such systems, over the years, while not so rapidly as
-today, were also improved upon, modified, speeded up, but could be used
-only in the point-to-point transmission of messages.
-
-While the railroads had been using the Morse code system (key and
-sounder) satisfactorily, they would have preferred a system whereby a
-printed record could be obtained. In the industrial world, too, there
-was need for a businessman’s printing telegraph—a means to type out
-messages, directly and interchangeably, to far-off associates. And there
-was always that dream, starting with the earliest telegraph
-experimenters, of being able to correspond instantly with one another
-anywhere in the world. Indeed, the need for all this had been known for
-many years, but not the way.
-
-It was after the turn of the century that telegraph engineers began in
-earnest to think about a system of telegraphy that would permit direct
-intercommunication by the printed word, and direct circuit connection to
-any outlying subscriber as in the telephone communication system.
-
-Up until then, apparatus for transmitting telegrams, such as that of
-Wheatstone & Cooke, Morse, Hughes, Barclay, etc., also the step-by-step
-stock tickers and bulletin printers, used various types of
-code-signaling devices in which the code varied in length as to the
-transmission of more frequent or less frequent letters.
-
-Now in order to provide a practical telegraph system permitting the
-interconnection of apparatus throughout the world, the first basic
-requisite is a standard signaling code; this code, moreover, must be of
-such nature as to use the simplest form of electrical signaling (such as
-make and break signals, or positive and negative signals), and the code
-should be of equal length for all characters.
-
-The permutation code, where combinations of five plus and minus pulses
-will give thirty-two selective positions, was suggested as far back as
-1833 by Gauss and Weber. Whitehouse, in 1854, and Barnett, in 1860,
-experimented further, using the permutation code to operate a recording
-mechanism. However, no practical means for actually printing letters and
-figures was found until 1882 when Jean Maurice Emile Baudot designed a
-multiplex system to permit the transmission of four messages in each
-direction over a single line circuit. Later, Baudot designed a tape
-printer in which the selecting and printing mechanisms comprised an
-ingenious arrangement of cooperating parts, including a rotating
-typewheel associated with a coded combiner wheel and five stationary
-elements selectively movable to received code positions, each element
-having an extending finger to be brought into contact with the periphery
-of the coded combiner wheel upon the completion of a selective code
-setting. When the code combination of the set fingers matched a code on
-the wheel, a print roller was released to press the recording tape
-against the typewheel and print the selected letter.
-
-Although the Baudot Multiplex was used extensively in Europe, engineers
-and inventors in the United States had not produced a practical 5-unit
-permutation-code teleprinter system. They were constantly searching for
-a unit code system requiring a minimum number of electrical impulses to
-operate a telegraph printer. Various types of relay systems using
-distinctive signal pulses were proposed. A three-unit-code system that
-showed promise, and did not require synchronism, used four different
-electrical pulse conditions: a high voltage positive or negative pulse,
-and a low voltage positive or negative pulse. Records show that many
-inventors played with this code and that John Burry, C. L. Krum, G. A.
-Cardwell, and J. C. Barclay, among others, built operable equipment
-using such a code arrangement. The following excerpt from Cardwell’s
-patent No. 905,497 of December 1, 1908, may be of interest. It describes
-the code arrangement of four different line conditions in three signal
-groups to produce 36 different code combinations.
-
- In order to energize the controller magnets in proper sequence to
- position the type wheel for printing a desired letter, a predetermined
- code or system of sending in the impulses is essential. In an
- instrument constructed by me in accordance with the present invention
- I have used the following:
-
- 1-2-1 letter space
- 1-2-3 carriage return
- 1-2-4 line space
- 1-3-1 type wheel shift
- 1-3-2 type wheel release

- 4-3-2 P
- 4-3-4
-
- The numerals in the above code or system indicate the sequence of the
- impulses through the relay contacts 1, 2, 3 and 4.
-
-Cardwell’s backers formed the American Telegraph Typewriter Company and
-sold shares, claiming a great profitable future for their apparatus. A
-few printers were built, but, on extended service tests, the
-high-low-voltage feature proved to be impractical and the company
-folded.
-
-J. C. Barclay of the Western Union Telegraph Company designed printing
-apparatus and perforated tape transmitting equipment for this type of
-system, but, after limited use of the high-low-voltage principle, he
-changed this feature to long and short pulses with discriminating
-relays. With later improvements, this system was put into service on a
-number of Western Union message circuits.
-
- _Note:_ Today, in the 1960s, the techniques of frequency division and
- electronics could be used for transmitting three different line
- conditions from a group of four different frequencies. In such a
- system, synchronism between send and receive terminals, or the
- start-stop method to control correct timing, is not needed. The
- transmission of any selected group of three, when received in
- succession at a teleprinter, will cause printing of a letter when the
- third receiving relay completes a circuit to the selected printing
- magnet. Transistor circuits with associated control elements could
- replace the relays.
-
-Telegraph companies in the United States were mostly using the Morse and
-increased its efficiency through development of quadruplex operation and
-high-speed transmission systems. However, the quest for a more efficient
-printing telegraph system persisted and various types were proposed and
-tried. All made use of codes that were impractical for
-intercommunicating systems and, while some were used in message service
-by the telegraph companies, they did not appear to have any great
-advantage over the Morse telegraph.
-
-In 1911, Western Union began investigating systems used in Europe. The
-first to be tested was the Creed, a system for transmitting and printing
-Continental or Morse code signals at high speed. After observing several
-other systems, the Murray Multiplex, an improved and modernized version
-of the Baudot Multiplex, was found to show better operating features
-and, due to the use of the five-unit permutation code, more efficient
-use of telegraph lines.
-
-By agreement with Donald Murray, and with his cooperation, the so-called
-Western Union Multiplex was developed, using Murray’s phonic wheel drive
-and synchronous correction. Western Union engineers designed tape
-transmitters and an autocontrol device for transmitting service signals.
-A keyboard-operated, five-unit-code, tape punch was supplied by the
-Morkrum Company. A page printer, which was later converted to print on
-gummed tape, was supplied by the Kleinschmidt Electric Company. The
-Western Union Multiplex was effective in increasing operating efficiency
-and came into extensive use throughout the system.
-
-From that time on, development of the Baudot permutation-code printing
-telegraph apparatus was furthered by various companies, such as Bell
-Laboratories, Western Electric, the Morkrum Company, the Kleinschmidt
-Electric Company, as well as the companies of J. E. Wright, L. M. Potts,
-and others.
-
-It appears that all of these inventors experimented with the idea of
-operating all transmitting and receiving apparatus at identical speeds
-to transmit a five-unit-code combination by first transmitting a pulse
-to start both transmitter and the distant receiver at the same time.
-Synchronous operation was obtained by electric motors equipped with
-governors to maintain correct speed; some used tuning-fork-controlled
-impulse motors. A system of five relays with progressive contact
-arrangements to cause cascade operation was also used to provide correct
-timing. Later, when correctly-timed, 60-cycle alternating current became
-available (see page 27), synchronous motors did the job.
-
-Teleprinter apparatus using this synchronous method worked very well for
-point-to-point transmission as was used by the telegraph companies and
-news-distributing organizations to carry local traffic. It did not,
-however, solve the sought-for plan for a teleprinter intercommunicating
-system. When attempts were made to connect printers at different distant
-points in a telegraph intercommunicating circuit while using the
-synchronous principle, false reception and printing errors would occur,
-due to variation in line circuit conditions and to a variation of the
-mechanical start operation at outlying teleprinters. This required
-frequent overline adjustment to keep the connected apparatus in phase.
-
-The following is an excerpt from a patent application of Dr. Louis M.
-Potts (later to become research engineer for the Morkrum-Kleinschmidt
-Corporation), filed June 17, 1909, giving his idea for achieving a
-teleprinter intercommunicating system on the synchronous principle. Dr.
-Potts was a very capable telegraph engineer. His early association was
-with the telegraph system of the Rowland Telegraphic Company which had
-limited use in the early 1900s.
-
- In those synchronous telegraph systems wherein the sending and the
- receiving commutator brushes constantly rotate, it is necessary to
- adjust these brushes so that they will approximately simultaneously
- engage corresponding segments. To effect this adjustment there is
- usually provided a special device embodying an additional segment on
- each commutator, and the adjustment consists in causing the brushes to
- arrive approximately simultaneously on this segment at the two ends of
- the line. Such adjustment is known as “finding the letter” and has to
- be made every time synchronism has been interrupted. According to the
- present invention, the necessity of providing additional means for
- performing the so-called operation of “finding the letter” is rendered
- unnecessary, since the transmitting and receiving commutator brushes
- at the two ends of the line start up afresh as it were for each
- signal.
-
-In a later patent application, filed October 11, 1913, Dr. Potts stated:
-
- This machine has also the advantage of being able to operate with a
- very short code. In order to adapt it to Morse circuits, it should be
- capable of operating with a code at least as short as the Morse code.
- In the present machine, I preferably employ a five unit code which,
- together with the starting impulse and the lag between signals, is
- actually shorter than the Morse code. Counting the five code impulse
- periods, the starting impulse period and the period of lag between
- impulses, each signal in my case, may be considered in comparison with
- the Morse code as being seven units long, whereas the Morse code is
- 8.5 units long. The average signal being shorter than the Morse, the
- delicacy of adjustment will be less and the distance of operation
- greater than a Morse telegraph for the same rate of transmission in
- words per minute.
-
-Dr. Potts, however, still depended on like synchronous operation at both
-terminals, and dual start, so he did not have the answer after all!
-
-John E. Wright, who in the 1890s designed and built step-by-step
-printing apparatus, including the Wright-Negron bulletin printer, also
-turned his thoughts toward the five-unit permutation code for printer
-operation and built several variations using the synchronous principle.
-The Superintendent of Telegraphs for the Delaware, Lackawanna and
-Western Railroad thought well of Wright’s apparatus and placed some in
-operation. But, here again, reliable operation could be maintained only
-in point-to-point operation. As will be noted in Chapter 2, Mr. Wright’s
-patents were purchased by the Kleinschmidt Electric Company in 1922.
-
-A paper issued by Siemens-Halske of Germany in January of 1917[1] states
-that the Siemens Pendel Telegraph “is among the forerunners of the
-eventual worldwide start-stop system for intercommunication by the
-printed word.” The following excerpt translated from that description
-briefly explains the operation:
-
- The Pendel Telegraph uses the five-unit permutation code to select
- characters, and operates on a start-stop principle. It is intended for
- station-to-station, one-way operation, the line current normally being
- closed to the positive side of the line battery. Transmission is under
- control of a keyboard with keys arranged as in a typewriter. Upon the
- depression of a key, the line battery is reversed, thereby
- transmitting a negative pulse to line which effects the start of both
- transmitter and receiver at the same time. Thereafter,
- five-code-combination pulses are transmitted, followed by positive
- current to line, thus restoring the circuit system to a normally
- closed line condition.
-
- The name “Pendel Telegraph” would make one think that the timing of
- the transmitter and receiver were under control of a swinging
- pendulum. This is not the case. However, it does have a plan for
- simulating the action of a pendulum by an arrangement of springs and
- semi-rotating weights to effect synchronism for each printing cycle;
- and energy is derived from a motor which intermittently winds a power
- mainspring to an even tension. This arrangement is started in
- operation at both terminals at the same time and provides isochronal
- motion at both transmitter and receiver for each transmitted
- character. Due to multiple operations of the springs and weights used
- to provide synchronous action, the operating speed is limited to four
- or five letters per second.
-
-In England, too, there was work being done along these same lines. Mr.
-H. H. Harrison, who is so well known for his contributions over the
-years in the telegraph field, devised printer apparatus using the
-five-unit code which is described in Herbert’s _Telegraphy_,[2] as
-follows:
-
- The instrument is provided with a Baudot 5-key keyboard, and has a
- step-by-step distributor which is mounted inside the casing. The
- standard Baudot alphabet is used, but each letter or character is
- prefixed by a positive starting impulse. Every time a key is depressed
- a universal bar is actuated which closes contacts giving the starting
- impulse and the distributors at both ends of the line step through six
- spaces. The combiner is of the electrical type invented by Baudot, and
- is similar to that used in Siemens’ new automatic printing telegraph.
- Five relays of the class used for telephone purposes are set at the
- receiving end, according to whether some of the stepping impulses are
- positive or negative. The distributor is a trunk hunting switch as
- used in automatic telephony, and consists of a ratchet wheel and
- stepping electromagnet. On the shaft of the ratchet wheel is fixed a
- wiper which sweeps over a semi-circular bank of contacts in response
- to the stepping impulses. Two-way working is secured by means of the
- differential balance.
-
- (The article ends with the statement that a typewriter keyboard is
- being constructed to replace the five keys.)
-
-It appears that all of these telegraph engineers and inventors
-envisioned a start-stop system and experimented with the idea of
-operating all transmitting and receiving apparatus at identical speeds
-by inserting a start signal before each group of letter code signals, to
-start both transmitter and distant receiver at the same time, and a stop
-condition between code groups.
-
-In the following chapters will be shown the contributions made by both
-the Kleinschmidt and the Morkrum companies in the printing telegraph
-field, and finally their joint efforts which were to lead up to the
-establishment of that now worldwide intercommunicating system, the
-TELEX.
-

- CHAPTER 2
- KLEINSCHMIDT
-
-
-Edward E. Kleinschmidt’s first direct contact with telegraph apparatus
-was during his employment as a young man, in 1893, by John E. Wright,
-whose firm had developed and was then manufacturing printing telegraph
-equipment known as the Wright-Negron bulletin printer for the Havas News
-Agency in Paris. These printers operated on the step-by-step principle
-at 30 words per minute. (To attest to their ruggedness, as late as 1951
-some of these machines were reported to be still in use!)
-
-Five years later, in 1898, Kleinschmidt started an experimental shop at
-122 Fulton Street in New York City. A sign over the door read,
-“Inventions Developed,” and he did experimental and developmental work
-for various customers (individuals as well as companies—including
-Western Union) on a time-and-material basis. In the beginning he had a
-project of his own going—a facsimile telegraph system. He submitted the
-system to Western Union in 1900 with the suggestion that it might be
-valuable for customer services, since a customer could write his
-telegram in longhand and insert the written message in the transmitting
-unit for transmission in facsimile to the telegraph central. The idea,
-however, was rejected. At that time the photoelectric cell for scanning
-the written message and electronic means for amplifying signals had not
-yet been developed; while the apparatus operated quite well over short
-circuits, evidently the time had not arrived for commercial facsimile
-telegraphy.
-
-The first telegraph apparatus job for the shop was brought in by Dr.
-George A. Cardwell, a dentist by profession. It was a partially
-developed printing telegraph using a three-unit code made up of
-combinations of plus-minus-high-and-low-voltage pulses (the code we have
-already discussed). The work for Dr. Cardwell was carried on until 1903
-when a working model was completed. It had a typewheel for printing and
-stops arranged in a circle; magnets under control of relay selection
-were used to set the stops according to the received code combinations.
-This arrangement operated well, and on a test over a Western Union
-circuit from New York to Baltimore it gave satisfactory results. As we
-have seen, however, the code arrangement proved unsatisfactory for
-general telegraphic use.
-
-Many customers came to the experimental shop with every type of idea
-imaginable; vacuum cleaners (The “Vacuna”), elevator signals, some early
-designs for Elmer Sperry’s gyrocompass were only a few. Kleinschmidt
-also set up a couple of side-line businesses, one for manufacturing
-automatic fishing reels under the trade name “Kelso,” another, the
-Aseptuloid Company, for making vaccination shields (some readers may
-well remember their childhood vaccinations being protected by a bubble
-of celluloid).
-
-Another customer was George M. Seely, who later was instrumental in
-bringing Kleinschmidt’s work to the attention of Charles B. Goodspeed
-and W. S. Moore (they were to become his financial backers—see page 14).
-Mr. Seely came to the shop in 1906 with a partially developed block
-system for electric trolley car railways. His plan was to use special
-devices attached to the trolley pole which would cooperate with
-stationary electrical controls at certain fixed points along the road.
-
-After working along these lines for awhile it became apparent that some
-inventive work would be required on Kleinschmidt’s part. Seely, in
-addition to time and material, then offered him a retainer for the
-assignment of any resulting patents.
-
-As plans and studies progressed, a number of railway signaling devices
-were developed, tested, and patented. A major item was the development
-of a telephone train dispatching system. A complete set of apparatus was
-exhibited in operation at the American Association of Railroads
-Communications Convention held in Los Angeles in 1910. The company name
-given this venture was the “National Telephone Selector Company,”
-located at 235 Greenwich Street, New York City. The telephone train
-dispatching system was installed on the Long Branch Railroad with 30
-stations connected with dispatcher headquarters at Red Bank, New Jersey.
-Another installation was made on the Baltimore and Ohio Railroad in West
-Virginia, connecting 38 stations with dispatcher headquarters at
-Fairbanks, West Virginia.
-
-Most of the patents assigned to Mr. Seely were eventually sold to the
-Hall Signal Company.
-
-Doing development work for others and assigning patents for a retainer
-did not satisfy Kleinschmidt’s ambitions. His interests being mainly in
-the telegraph, he set out to design and build a piece of apparatus that
-the telegraph companies could use. A keyboard-operated perforator to
-punch the Morse code in a tape for automatic transmission at high speed
-looked like a promising subject, since the tape punches in use at that
-time had a three-key arrangement—one each for dot, dash, and space.
-
-Kleinschmidt’s first keyboard-operated, Morse-code perforator was
-constructed in 1911 and exhibited to the Western Union Telegraph
-Company. Mr. G. R. Benjamin, their chief engineer, and Mr. Emmett R.
-Shute, a vice president, thought well of the machine and, after testing
-it, gave Kleinschmidt an order for fifty. This order spelled success. To
-celebrate the event, Kleinschmidt invited his brothers, Bernard, Fred
-and William, and their families to a dinner party at a distinguished
-restaurant. Soon thereafter (1913), the Kleinschmidt Electric Company
-was organized, with the brothers as incorporating officers.
-
-The Kleinschmidt Keyboard Perforator came into use by telegraph and
-cable companies throughout the world where Morse, Wheatstone, or Cable
-codes were used to transmit telegrams. It was also used with Western
-Union’s Barclay system which had its own code. The device was later
-manufactured by Teletype Corporation under the name “Teletype
-Perforator” and used by the U. S. Government where it served its purpose
-for high-speed Morse transmission during the war period (see figure 1).
-
-In the years 1911 and 1912, the Western Union Telegraph Company, in
-looking toward higher operating efficiency over their trunk circuits,
-decided to test the Creed high-speed Morse and the Murray Multiplex, and
-invited both companies to bring their apparatus to New York. It was on
-this occasion that Kleinschmidt became acquainted with Mr. F. G. Creed,
-who, upon observing the Kleinschmidt keyboard perforator at Western
-Union, was impressed by its performance and said that there would be a
-good market for it in England, especially as a keyboard punch for the
-Creed high-speed Continental-Morse-code system. As a result of that
-conference he asked for ten as a trial order. These perforators were
-shipped to London in due time and gave satisfactory service. The British
-Post Office Telegraph evidently had heard about this new perforator and
-sent a letter to the Kleinschmidt company asking for a demonstration at
-their London headquarters.
-
-Now it happened at that time that Kleinschmidt was extremely busy with
-the development of a five-unit-code typebar printer for the new
-Multiplex—and this was urgent since the first model was to be put on
-competitive test with a typewheel printer submitted by L. M. Potts and
-the Western Electric typewheel printer which was then in use. Therefore,
-he felt he should not lose a month or two in this developmental work for
-a trip to London. So, his answer to this important invitation was that
-he could not personally bring one of his perforators for exhibit but
-that he would ask Mr. F. G. Creed to do so. Mr. Creed agreed and set up
-a formal exhibit for the Post Office engineers; he consequently received
-an order for twenty Kleinschmidt perforators. Further correspondence
-with Creed resulted in an order for one hundred and a request that
-Kleinschmidt come to London the next year (1914) to negotiate a contract
-to supply his keyboard perforators for the Creed high-speed Morse and to
-set up a sales agency with Creed for certain territories.
-
-While in London in the summer of 1914, Kleinschmidt visited the Managing
-Director of the Post Office Telegraph at his office to apologize for
-having had Mr. Creed exhibit the Kleinschmidt perforator instead of
-bringing it personally as had been requested. The Managing Director
-replied that Mr. Creed had indeed given a very good operating exhibition
-of the device and that an order for twenty had been placed with him.
-“However,” he added, “you know, we sent you an official invitation and
-expected your appearance with your machine!”
-
-To continue: Upon observing the change in systems at Western Union
-(switching from the Barclay to the Murray Multiplex), the Kleinschmidt
-Electric Company, who had been experimenting in the development of a
-telegraph typewriter, built a receiving teletypewriter for the
-multiplex. It was a magnet-operated, five-unit-code typebar page
-printer, using the Underwood typewriter mechanisms as a basis; and it
-was completed in time for test and evaluation at Western Union in
-competition with the typewheel printers of both L. M. Potts and Western
-Electric.
-
-The Western Electric machine was given the number 1A, Mr. Potts’s, 2A,
-and the Kleinschmidt printer was 3A. The final outcome of the tests was
-the selection of the Kleinschmidt model, and the company received an
-order for five machines, to include a spare, to equip the New York
-terminal of a New York-to-Boston, four-channel multiplex system. The
-order was filled in a short time and the machines were put on test.
-

-
- [Illustration: Fig. 2
- 3B Typebar Page Printer of Kleinschmidt Electric Company
- _from Museum of Kleinschmidt Division of SCM Corporation_]
-
-Kleinschmidt watched the operation of his machines in service almost
-every day and was continually on the lookout for possible ways to
-improve and simplify the apparatus. The tests ran through to completion
-satisfactorily, and, upon submitting an improved design, numbered the
-3B, the Kleinschmidt Electric Company received an order for one hundred
-typebar page printers. The 3B thereafter became standard apparatus and
-additional orders were placed as the multiplex system at Western Union
-expanded (see figure 2).
-
-Several years later, Western Union efficiency engineers found that, due
-to circuit failures, certain parts of messages would have to be
-repeated. Because this meant retyping the message, they felt, and for
-other reasons as well, that printing the received messages on tape would
-be more economical, since corrections could be inserted without
-repeating the entire message. To meet this requirement, the typebar page
-printer was redesigned for printing on tape. This was accomplished by
-using the same selection controls and operating the typebars to print
-downward on the tape instead of upward against the platen as in the page
-printer. A tape gummer to attach the tape to a message blank was also
-designed. The 21A, later No. 22, tape printer was ordered in quantity
-thereafter.
-
-Seeing the possibility of using their typebar page printer for
-direct-line service, the Kleinschmidt company built a motor-driven
-send-receive unit having a single contact transmitter which operated
-under control of a code-perforated tape to transmit seven signals in
-succession: one start, five code, and a stop signal. The receiving unit
-had a seven-segment commutator, one segment for start, five for code,
-and one for stop, and a rotating brush to pick up and transmit the
-received code signals to the printing unit. This apparatus was installed
-at the United Press for news distribution to their connected newspapers.
-Another set was installed at the Louisville and Nashville Railroad for
-station communications, and still another in New York City at the
-Equitable Life Assurance Society between their downtown and uptown
-offices. In connection with the latter installation, the Equitable
-people asked permission to install the printing apparatus on the
-telephone line and there was objection from the telephone company.
-However, after some consideration they finally agreed that the apparatus
-could be installed but warning that should it create interference with
-the telephone line it would be removed immediately. As it turned out,
-the printer operation over this telephone circuit did not create any
-interference and the apparatus remained in service a long time (figure 3
-).
-

-
-The Kleinschmidt Electric Company now began to have financial
-difficulties. Edward Kleinschmidt was borrowing wherever he could. There
-was no large quantity production and evidently his charges for the
-apparatus delivered were too low. At any rate, early in 1917, Mr. Seely
-suggested that he get financial help to carry on and it was here that
-the following gentlemen entered the picture: Charles B. Goodspeed of the
-Buckeye Steel Casting Company; Paul M. Benedict, assistant to the
-president of the C. B. & Q.; Edward Moore, son of Judge Moore of the
-American Can Company; Eldon Bisbee, a New York lawyer; and one of Mr.
-Bisbee’s clients, Albert Henry Wiggen, who was then president of the
-Chase National Bank. With their financial backing, the company was able
-to continue with further developmental work on simplified and more
-efficient apparatus. Orders for various types of equipment for the
-Western Union Multiplex and for the Morse code keyboard perforator came
-along, but developmental costs were high and still more capital
-investment was required; Kleinschmidt would then borrow from the Chase
-Bank. Every so often at the Kleinschmidt company’s directors’ meetings,
-Mr. Holly, cashier of the bank and also a director of the company, would
-state that the Kleinschmidt loan “stood out like a lighthouse,” so a
-vote for an additional stock issue was carried and the loan paid.
-
-Along about 1919 the Kleinschmidt company had completed a satisfactory
-keyboard-operated typebar teleprinter for intercommunication systems
-(see figure 4). The Kleinschmidt Telegraph Typewriter, as it was called,
-was installed at the New York City News, the Panama Canal, and at the
-Brooklyn Union Gas Company (fig. 5).
-
-In 1922, Edward Kleinschmidt, having learned that Mr. J. E. Wright had
-discontinued further developments in the telegraph field, proposed the
-purchase of his patents, stating that this acquisition would broaden the
-Kleinschmidt company’s patent situation. The proposal was carried, and,
-after negotiations, Mr. Wright’s patents were bought for 100 shares of
-the Kleinschmidt Electric Company’s common stock.
-
-In 1923, the Kleinschmidt Telegraph Typewriter was exhibited at the 20th
-Annual Business Show in New York and created a great deal of interest.
-In 1924, a complete telegraph system was engineered and set up for the
-Mexican government. (An engineer from Western Union was borrowed to help
-with this job.)
-
-One day, in 1923, after some correspondence with Samuel Samuel & Co.,
-Ltd., through whom the Kleinschmidt company received orders from Japan
-for the Morse code keyboard perforator, the Japanese Telegraph
-Administration sent one of their telegraph engineers, Mr. Y. Okomoto, to
-the company’s headquarters to assist in working out a keyboard
-arrangement of Japanese characters for a simplified alphabet consisting
-of 88 characters which the Japanese Telegraph Administration had
-devised. The five-unit code could not be used since only 64 selective
-positions could be had. So the telegraph typewriter mechanisms were
-changed to six-unit-code operation, which worked out very well. The
-Kleinschmidt company, and later Morkrum-Kleinschmidt, received
-continuing orders for the six-unit-code telegraph typewriters.

- CHAPTER 3
- KRUM AND MORTON
- (MORKRUM)
-
-
-Mark Morton, head of the Western Cold Storage Company in Chicago, and
-cold-storage engineer Charles L. Krum, the vice president of the firm,
-entered the telegraph field quite by accident. A young electrical
-engineer named Frank Pearne, in 1902, had some ideas for a printing
-telegraph machine and needed financial backing to carry on his
-experiments. One of his contacts happened to be Joy Morton, the founder
-of the Morton Salt Company. Joy Morton became interested enough to
-become Pearne’s backer, and prevailed upon brother Mark to set up a
-laboratory in the attic of the cold-storage plant for Pearne’s
-experiments.
-
-It seems that after a year or so, Pearne lost interest in his invention
-and went into the teaching field. He proved to be a very successful
-professor at Armour Tech where he remained until his death.[3] But
-Pearne’s work was not in vain, for Charles L. Krum had become intensely
-interested and carried on the work with further inventions of his own.
-Indeed, he filed his first patent application on August 20, 1903, which
-proposed the use of a code comprising four signals: a positive pulse or
-a negative pulse of low voltage, and a positive or negative pulse of a
-higher voltage. Four additional patents were filed, the last in 1906.
-
-C. L. Krum then set about building a machine which was demonstrated in
-1906 and looked promising enough to form a company to further develop
-it. This company was made up of the Mortons (brothers Joy and Mark) and
-the Krums (Charles L. and his son Howard who had just finished college).
-The combination of their names, of course, resulted in “The Morkrum
-Company,” which was incorporated in the State of Maine on October 7,
-1907. The charter stockholders were Joy Morton, who shouldered the
-greatest financial burden; Charles Krum; Joy Morton’s secretary, Daniel
-Peterkin (he later became an officer of the Morkrum Company); Mark
-Morton; and Sterling Morton (Joy’s son, of whom we shall be hearing more
-later on). The working capital of the new company amounted to
-$150,000.00.
-
-Charles Krum’s son Howard, after graduation, joined with his father in
-the developmental work of this new company and, due to his studies in
-electrical engineering, was able to help his father considerably. His
-first love and intended career was music, but he put this aside in favor
-of his father’s telegraph printer. However, a tune on the piano which he
-always kept in the laboratory would help him solve many a difficult
-problem.
-
-In 1908 the Krums developed and produced a working model of the
-four-unit-code, plus-minus, high-low-voltage system, which was applied
-to operate the mechanism of an Oliver typewriter. The system was then
-given an operative test on the wires of the Chicago and Alton Railroad,
-of which Joy Morton was a director.
-
-As their research work progressed, Howard studied the various systems in
-current use and, with his father, decided to abandon the plus-minus,
-high-low-voltage system. They turned instead to a system using the
-five-unit permutation code as employed by Baudot in his multiplex
-telegraph in which synchronized terminal apparatus with periodic
-correction was the controlling feature.
-
-Their first joint patent describes a plan for accomplishing synchronized
-reception with transmission using a system of five relays interconnected
-to operate in successive cascade form; thus, when the relays at both
-terminals are correctly timed for successive operation, they will
-transmit and receive the five pulse combinations of the Baudot code. For
-transmitting and receiving the code pulses, each of the five relays has
-an additional contact. To start the relay cascade operation, a start
-relay is added at both terminals and operated by a start pulse which
-precedes each code transmission. It seemed natural for the Krums to turn
-to a relay system at first, since, from his work with the
-three-unit-code, high-low-voltage system, C. L. Krum was experienced
-with the possibilities of relay operation.
-
-The system of the relay chain in cascade operation was employed to
-operate a page printer using the mechanisms of the Blickensdoerfer
-typewriter which had a three-row typewheel. The Postal Telegraph Company
-became interested and bought a number of these printers in 1910. This
-was the first sale of Morkrum apparatus and provided enthusiasm for the
-Krums for further research, which led to the substitution of a
-governed-motor-driven brush distributor to replace the relay cascade
-system. For this new plan the motor at the receiving printer operated at
-a slightly higher speed and was held in continuously synchronous
-operation with the transmitter by the periodic transmission of a
-correcting pulse. The new code selecting and printer control system was
-also adapted to operate the mechanism of the Blickensdoerfer typewheel
-typewriter. The idea worked out better than the cascade relay system,
-and a number of printers using this method were constructed and named
-the “Morkrum Blue Code.” A few were put in service at the Postal
-Telegraph Company.
-
-The Associated Press (AP) became interested in the Morkrum “Blue Code”
-printer system as a replacement for the low-speed Morse system which was
-being used to transmit news items to newspapers in many cities. Here,
-continuous transmission under control of a code-punched tape, as used in
-the Morse code system, was a requirement, so Messrs. Krum set to work
-and designed a keyboard-operated, five-unit, Baudot-code perforator and
-an automatic punched-tape-controlled transmitter. This apparatus was
-installed at the New York headquarters in 1915 and receiving printers
-were gradually installed throughout the Associated Press system. The
-following excerpt and picture (fig. 6) from Oliver Gramling’s book,
-_AP—The Story of News_,[4] describes the introduction of the system to
-the Associated Press:
-
- The tide of news by telegraph had continued with the years. Facilities
- had been improved, the Morse clicked into virtually every town in the
- country, but the old method was the same. Day in and day out, sending
- operators took dispatches, translated them into the dash-dot of code,
- and the telegraph keys sent the signals on the circuits at a rate of
- twenty-five to thirty-five words a minute. In member newspaper offices
- along the line the Morse sounders clack-clacked busily and receiving
- operators translated the code symbols back into words, copying the
- stories in jerky spurts. The news of more than half a century had been
- handled that way.
-
- For some time, however, Charles L. Krum, a Chicago cold-storage
- engineer, and his son Howard had been working to perfect an automatic
- machine which would send the printed word by wire at greater speed
- without the intermediary of code. They called their invention the
- Morkrum Telegraph Printer—coining the word Morkrum by combining the
- inventor’s name with the first syllable in the last name of Joy
- Morton, a Chicago businessman who financed them.
-
- [Illustration: Fig. 6
- A SENDING OPERATOR SAT AT A KEYBOARD LIKE THAT OF A TYPEWRITER.
- Reproduced from _AP—The Story of News_, by permission of Associated
- Press.]
-
- Several other automatic telegraphic devices were being promoted, but
- (Kent) Cooper and engineers in the Traffic Department decided Krum’s
- machine held the most promise for their purposes. Tests got under way.
- In the Associated Press headquarters, which had been moved seven
- blocks from the old Western Union building to 51 Chambers Street, a
- sending operator sat at a keyboard similar to that of an ordinary
- typewriter. As he struck the keys, copying the dispatches before him,
- the machine perforated a paper tape with a series of holes, each
- combination representing a letter. The tape fed into a box-like
- transmitter which transformed the tape perforations into electrical
- impulses and sent them along the wires into the receiving machines in
- newspaper offices. These impulses actuated telegraph relays and set
- the receiving Morkrum machines automatically reproducing the letters
- which the sending operators were typing miles away.
-
- The tests demonstrated that the Morkrum could transmit news hour after
- hour at the rate of sixty words a minute and the copy was delivered
- clean and uniform. Thus began the slow extension of Morkrum
- transmission to the whole leased wire system, replacing the “brass
- pounding” Morse keys. It was a transition that required years and
- until it was completed both Morse and Morkrum worked side by side in
- many places.
-
-An interesting story appeared recently in “The AP World,”[5] giving some
-recollections of AP’s first field maintenance man, Royal (Roy) Bailey,
-then aged 71 and living in retirement in California. He still remembers
-the AP’s first printing telegraph machines, the article says; in fact,
-he helped make them, for he was a mechanic in the Morkrum Company’s
-factory in Chicago. When the Morkrum Company shipped the first machines
-to AP headquarters, Bailey went along with the machines to install and
-maintain them, although he remained on the Morkrum Company’s payroll. He
-eventually installed AP printers all over New York City and Connecticut,
-in Newark, Philadelphia, Baltimore and Washington, and in Chicago, St.
-Louis and Kansas City. He recalls that Morse telegraphers “used to groan
-when they first saw him.” The early teleprinters were hard to keep
-synchronized, Bailey further recalls, and copy boys had to check the
-speed frequently by sighting the striped motor flywheel through a tuning
-fork. (Many of those copy boys, he says, including Mickey Burt and Henry
-Elling, became AP engineers.)
-
-As the experimental and developmental work continued at the Morkrum
-plant, Howard Krum studied all types of start-stop systems and found
-that synchronous control was the basis of all systems. After
-experimenting with various ideas his thoughts turned to a plan to make
-the start of the receiving unit somewhat independent of the transmitting
-unit start, thus avoiding irregularities then present in transmitter
-start devices. This idea led to the construction of a permutation-code,
-start-stop system, using segmented commutators with rotating brush
-distributors at both transmitting and receiving units and a start magnet
-for each to control start-stop operation.
-
-In this system the transmitter start magnet, when energized, releases
-the transmitting brush, which immediately contacts the first segment to
-transmit a start pulse to operate the receiver start magnet; the
-five-unit-code signal combination follows and both transmitting and
-receiving units are stopped. The apparatus was applied to control the
-selecting and printing mechanism of the Blickensdoerfer typewheel
-typewriter and named the “Morkrum Green Code.” This improved apparatus
-soon replaced the Blue Code printer at Associated Press and other
-installations (see figs. 7 and 7A).
-
-In this connection the following additional comments of Mr. Bailey may
-be of interest:[6]
-
- In 1919 I installed the New York-Washington circuit, with drops at
- Philadelphia and Baltimore. This was a new type of printer using what
- we called the Green Code. This was considered an improvement over the
- old Blue Code, which meant a rearrangement of the receiving mechanism,
- but still the machines made use of a typewheel....
-
- Our biggest job of all came in 1923 when we changed over all the old
- Blue Code typewheel printers in the New York area to the new style L.
- C. Smith typebar printers using Green Code. (Morkrum bought L. C.
- Smith typewriters and added new machinery to them. Those printers
- became the famous Model 12.)
-
-As we have seen, a number of inventors had patented ways and means to
-adopt the five-unit code for operating a telegraph printer system by the
-transmission of a start pulse to start both transmitting apparatus and
-the distant receiving apparatus at the same time, followed by
-transmission of a selected code and a stop pulse. To achieve successful
-operation, very close speed adjustment was required. At first, this was
-achieved by the use of governed motors and, later, when accurately
-timed, 60-cycle alternating current became available, the problem of
-synchronous operation of send and receive stations was solved by the use
-of synchronous motors.
-

-
-Telegraph printer systems of this type were used by telegraph companies
-for city-to-city transmission of telegrams and by news-gathering and
--distributing organizations to transmit the news from headquarters to
-newspapers in different cities. While start-stop systems of this type
-were used successfully on press circuits and on telegraph message
-station-to-station circuitry, trouble was experienced when a number of
-printer send-receive units were set up in an intercommunicating system.
-Here it was found that the receiver start was not always in time with
-the transmitter start, due to varying line circuit conditions and a
-variation in the start release mechanism at connected stations.
-
-It seems odd that synchronous systems, where both transmitter and
-receiver were started at the same time (requiring both transmitter and
-receiver to maintain synchronism), held the field for so long a time,
-thus limiting telegraph transmission to one-way operation.
-
-It evidently took a mind not bound or hampered by the standard and
-accepted way of operating synchronous systems to discard such old ideas
-and to set forth boldly on a new pattern which, in reality, differed but
-slightly from the then-established synchronous systems, and to sow the
-seed for starting further developments leading to the present telegraph
-typewriter, TWX, and TELEX intercommunicating systems. Such a man was
-Howard L. Krum, who, in further thinking on the subject, came upon the
-almost simple idea of having the transmitter start the receiver rather
-than having them both start at the same time. This arrangement required
-higher speed operation of the receiver and therefore the receiving code
-pulse positions were spread over a shorter area, which meant
-progressively decreasing the angular division of the receiving members.
-Then, to set the received start pulse in the most favorable position
-with relation to the following code signal reception, an orientation
-adjustment of the receiver start position was provided.
-
-(Note: On June 20, 1961, Kleinschmidt wrote to Howard Krum—then in
-retirement in California—giving a short description of the Morkrum
-Company activities, including the wording of the above last two
-paragraphs, and asking him to write the Morkrum story. Howard Krum
-replied on July 3, 1961, indicating his approval and saying that he
-would be glad to put together some notes for Kleinschmidt. It was quite
-a shock, therefore, when a letter was received from Howard Krum’s son,
-Charles, in September of 1961, telling of his father’s sudden serious
-illness. Then, regretfully, it was not long afterwards that word was
-received of Howard Krum’s death on November 13, 1961.)
-
- [Illustration: Fig. 8
- Morkrum Company No. 12 Typebar Page Printer
- _Picture through courtesy of Teletype Corporation_]
-
-Howard Krum’s improved method for operating start-stop, permutation-code
-telegraph systems was first applied to the Morkrum Green Code apparatus
-to control the selecting and printing operations of the Blickensdoerfer
-typewheel typewriter.
-
-At this time the Kleinschmidt company and other manufacturers were
-starting to produce permutation-code, start-stop telegraph printers
-using typebar printing like the more modern typewriters which began
-rapidly to replace the Blickensdoerfer, the Hammond, and the other
-typewheel printing typewriters. Observing this situation, the Morkrum
-Company started intensive development work to produce the No. 12 typebar
-page printer, using the typebars and operating mechanism of the L. C.
-Smith typewriter and platen of a Woodstock typewriter (fig. 8).
-
-Further developments produced the Morkrum No. 11 tape printer which used
-the Baudot combiner method for selecting and printing characters under
-control of start-stop, send-receive devices. The No. 11 was a small,
-compact tape printer operating at fifty words per minute. Quite a number
-were put into service at hotels and elsewhere for local message service
-(fig. 9).
-
- [Illustration: Fig. 9
- Morkrum Company No. 11 Tape Printer
- _Picture through courtesy of Teletype Corporation_]
-
-The new No. 12 typebar page printer found numerous applications. It
-replaced the Green Code and the earlier Blue Code wherever used. The new
-No. 12 was installed at Western Union, on some railroads, and in the
-Chicago Police telegraph system. The No. 12s were also installed by
-Postal Telegraph on intercity circuits and used as receiving units for
-the Postal Multiplex. The Postal Multiplex had been designed by Morkrum
-and Postal engineers with the consultant assistance of Donald Murray who
-was a friendly associate and had a license agreement with the Morkrum
-Company covering some of his patents. A few No. 12 Morkrums were shipped
-abroad for use with the Murray Multiplex; the British Post Office
-Telegraph and the Australian Telegraph Administration were customers.
-
-Late in 1924 the Morkrum Company and the Kleinschmidt Electric Company
-joined to form the Morkrum-Kleinschmidt Corporation. A story telling of
-the union of these two companies was published by _Fortune_ magazine in
-March of 1932.[7]
-
-Before going to that story, it may be of interest to describe an
-important event concerning the change in the supply of electric power
-from direct current to 60-cycle alternating current and the final timing
-to exactly 60 cycles per second of all A.C. power supplies so that our
-electric clocks may be connected to an A.C. outlet and give correct
-time.
-
-The advent of correctly timed, 60-cycle A.C. electric power, available
-throughout the nation, was a great boon to the designers of printing
-telegraph apparatus and some types of facsimile telegraph and picture
-transmitting systems. In prior years, overline synchronization of send
-and receive apparatus was always a problem and never perfect. Today,
-synchronizing apparatus between terminals becomes the simple matter of
-providing 60-cycle A.C. synchronous motors. Just plug into a power
-outlet and you have “sync”!
-
-Henry Ellis Warren, a clock maker, noting the change in electric power
-service from direct current to 60-cycle alternating current, set about
-to build a motor to operate at 60-cycle speed but found that the
-60-cycle frequency did not always hold to form, and when applied to
-running a clock, did not hold correct time.
-
-The following excerpt, from _The Romance of Time_,[8] tells of Warren’s
-activities which led to synchronizing 60-cycle alternating current to
-exact time:
-
- _Synchronous Electric Time_
-
- One of the most important of all contributions to horology is the work
- of an American who has earned the title, “Father of Electric Time.”
-
- Henry Ellis Warren was graduated from Massachusetts Institute of
- Technology in 1894. In 1907 he married and settled in Ashland,
- Massachusetts. Here it was that he began to work out his idea for
- electrically operated timepieces.
-
- His first product was an ingenious battery-operated clock. In 1914 he
- organized the Warren Clock Company and set up production in a barn on
- his farm. Yet he knew the battery clock was not his goal, for direct
- current offered no means of accurate regulation. Direct current flows
- constantly in one direction only, like water down a river or like the
- passage of time. On the other hand, alternating current changes
- direction regularly, like the oscillation of the balance wheel in a
- watch. But instead of the usual five times a second of the balance
- wheel, most alternating current completes its trip forward and
- backward sixty times a second. Obviously, a clock “geared” to such a
- frequency would run as reliably as the current.
-
- In 1916, after several years of extensive experimentation, Warren
- developed a motor which would start by itself, run on alternating
- current, and carry without difficulty the load of reduction gears
- driving the clock hands. It could also handle the cams and contacts of
- an alarm clock or set in motion a striking or chiming mechanism.
-
- Then came the test. He plugged the clock into the power socket. It
- commenced to run. Weeks of observation and checking showed an
- irregular error of as much as ten to fifteen minutes a day.
-
- Convinced that his clock was right, Warren discovered that the
- alternating current frequency delivered to his barn factory was off
- half a cycle per second—59½ and not 60 cycles. This slight deflection
- would produce that much time loss in a 24-hour run. When he informed
- the electric company of this error, he was met at first with polite
- disbelief. Yet he showed such a comprehensive knowledge of the subject
- that the company began to recheck their standards.
-
- Warren built several more synchronous clocks and a master regulator of
- his own design for power-station use. On one dial of his master clock
- there were two hands, black and gold. The black hand was connected to
- an accurately adjusted pendulum clock, beating seconds. The gold hand
- was driven by the gear train of one of his electric clocks. As long as
- the two hands revolved together, the current cycles were exactly 60
- per second. Set up in a power station, this allowed the operator to
- adjust the turbine generators as needed to keep the two hands of the
- master clock together. Thus all other properly set electric clocks on
- the same system would keep the same time automatically.
-
- The Edison Electric Illuminating Company of Boston tried out the
- master clock on October 23, 1916. Since then this regulation has
- continued.
-
- Other power companies adopted Warren’s master clock. Today virtually
- all alternating current furnished in America is similarly checked.
- Practical electric time is available at the light socket almost
- everywhere. But there are additional benefits.
-
- Standardizing the frequency expanded the market for current to run the
- increasing number of clocks in use. Yet, from the consumer’s point of
- view, each clock draws little current, costing but a few pennies a
- month. Uniform frequency also gave more even speeds in motor-driven
- machinery, with a resultant improvement in product. It made easier the
- joining of one power station to another. Synchronous motors used in
- certain meters and recorders produced better, more accurate records at
- lower cost.
-
- The Warren enterprise expanded rapidly. The battery clock was
- discontinued. The red barn was no longer large enough, and new space
- was acquired. The trade mark “Telechron,” meaning “time from a
- distance” (from two Greek words), was used to identify all products of
- the company. The firm name was changed to stress the name Telechron,
- and in 1952 a merger was made with the General Electric Company.
- Plants are now operated in Worcester as well as in Ashland,
- Massachusetts.
-
-And now back to the telegraph field....

- CHAPTER 4
- Morkrum-Kleinschmidt Corporation
- (later renamed “Teletype Corporation”)
-
-
-During and after the first world war, both the Morkrum Company and the
-Kleinschmidt Electric Company were progressively developing and
-producing telegraph apparatus and bringing out new and improved
-operating devices to a point where conflicting patents were at issue.
-This meant infringement litigation which might destroy both companies.
-Neither company could obtain orders in sufficient quantity to make the
-manufacturing of apparatus profitable, and, with costly development work
-at hand, more capital investment was a continuous requirement.
-
-The following excerpts from the March 1932 issue of _Fortune_[9] tells
-of the final joining of the two companies.
-
- The Morkrum Co. had no profits to show for its efforts, and one can be
- fairly safe in assuming that no other maker of telegraph printers made
- profits. There were competitors, of course. Even the first telegraph
- invented by Samuel Morse had a printer, but it printed in dots and
- dashes instead of in letters of the English alphabet. That original
- Morse printer was abandoned as far back as 1844 because a man who
- could be trained to read dots and dashes could just as easily be
- trained to listen to them. The problem of getting a printer to print
- the alphabet was faced by inventors more than half a century ago, and
- it was not really a difficult problem. The difficulty was to invent a
- printer that was not too complicated and delicate to be reliable, that
- was simple enough to be manufactured for a few hundred instead of a
- few thousand dollars.
-
- This difficulty occupied many minds other than the Morton-Krum
- intelligences. The most noteworthy of Morkrum Co.’s rivals in
- printer-making was Edward Kleinschmidt, an inventor who had all the
- inventor’s legendary devotion to his task and to nothing else. His
- creations included a vaccination shield, an automatic fishing reel,
- and the perfection of the Wheatstone perforator. He had been tinkering
- with a telegraph printer in one form and another since the beginning
- of the century. In 1917 his project was revamped. It had the financial
- backing of Charles B. Goodspeed, of the Buckeye Steel Casting Co.;
- Paul M. Benedict, assistant to the president of the C. B. & Q.; Edward
- Moore, son of Judge Moore of American Can fame; Eldon Bisbee, a New
- York lawyer; and one of Mr. Bisbee’s legal clients, Albert Henry
- Wiggin, then president of the Chase National Bank. It was Mr.
- Goodspeed, a quiet, retiring gentleman, who supplied most of the
- corporate (as distinct from inventive) energy of the Kleinschmidt
- Electric Co....
-
- In the years from 1917 to 1924 the Kleinschmidt and the Morkrum
- companies became the leading makers of telegraph printers, but they
- did not have an easy row to hoe. Their only possible customers were
- the two great telegraph companies, the Telephone company, the
- railroads, and an occasional outside business such as a press
- association. The competition was disheartening, and it became keener
- with the elevation of Sterling, son of Joy Morton, to the presidency
- of the Morkrum Co., an elevation that was mainly a War-time accident,
- for Sterling Morton had resigned from his father’s company to enlist
- in the Army, had been rejected because of a small steel plate in his
- anatomy, and had chosen the Morkrum Co. as an alternative. Engineering
- progress was made, sometimes under ludicrous circumstances.
-
- There was one occasion when Sterling Morton, about to sail for Europe,
- heard that the Kleinschmidt Co. was about to bring out a simplex
- printer. Up to that time both companies had been making printers for
- use with multiplex machines. Mr. Morton was afraid that Mr.
- Kleinschmidt was about to anticipate him in the simplex development
- which was the forerunner of the present teletypewriter. This was a
- contingency which Mr. Morton could not well permit. On the spur of the
- moment, he called on Howard Krum, who happened to be in New York. They
- bought a drawing board, hired a room at the Princeton Club, and worked
- for twenty-four hours trying to design such a machine. Completely
- baffled by one small detail, they gave up and took a bus for Coney
- Island. On the way, Howard Krum doubled up in sudden ecstacy and
- inspiration. They rushed from the bus at Coney Island, entered a soda
- fountain, and on the spot designed the machine on the back of an
- envelope. This simplex machine of the Morkrum Co. and the one
- developed by Kleinschmidt at the same time are the machines which make
- Teletype commercially important, the substance of the business today.
-
- But engineering progress was not business progress. Both companies
- from the standpoint of profits were failures. Their few customers
- played them off against each other. In despair, they were both willing
- to sell out. At one point Mr. Goodspeed offered the Kleinschmidt
- company to Mr. Newcomb Carlton of Western Union for $412,000, the
- amount invested in it. Mr. Morton sold his company in all but fact to
- Mr. Charles G. du Bois, then president of Western Electric, but Mr. du
- Bois went off to Europe, and his substitute refused to see any merit
- in the deal. So it fell through. Unable to sell themselves to their
- customers, they tried selling themselves to each other. In 1923
- Messrs. Goodspeed and Morton came to terms. The Morkrum Co. signed the
- agreement and, everything arranged, Mr. Goodspeed went off to bicycle
- with his wife in South Africa—whereupon his company suddenly changed
- its mind.
-
- That was the situation of these two unfortunate companies in 1924 when
- Mr. Morton started a suit for patent infringement against his rivals.
- A counter suit was promptly filed. Mr. Goodspeed was quite right when
- he said the suits would ruin both—there was every prospect that by the
- time the courts had settled things, the patents would have been in
- such a snarl that neither could do anything. The suit, in fact, was
- Sterling Morton’s way of bringing matters to a head. So, figuratively
- speaking, on the courthouse steps they merged.
-
- The terms of the merger as embodied in the six-line agreement (it was
- later made over into a twenty-five-page legal document which concluded
- by saying that in case of dispute the six-line agreement should be the
- final authority) were these: each of the old companies received a half
- interest in the common stock (10,000 shares) of the new company;
- 15,000 shares (callable at 105) of the new company’s preferred stock
- should be divided according to the assets of the old companies.
- Actually, 13,979 shares of preferred were issued, the majority going
- to the Morkrum group.
-
-And so it was that the agreement to join both companies under the name
-Morkrum-Kleinschmidt Corporation was consummated and chartered in the
-State of Delaware on December 29, 1924, with Sterling Morton as
-President, Howard L. Krum as Vice President in charge of manufacturing,
-and Edward E. Kleinschmidt as Vice President in charge of development,
-patents and foreign sales.
-
-One of the first decisions to make was whether the Kleinschmidt plant in
-Long Island City or the Morkrum plant in Chicago would be the
-headquarters for the new company. The Kleinschmidt company was on a
-27,000-foot leased floor in a building which R. H. Macy Company had just
-purchased to use for a warehouse, and negotiations had been going on for
-some time for the purchase of the Kleinschmidt lease—the sum of
-$25,000.00 having been offered. When the union of the two companies was
-decided upon, an agreement to vacate on the terms offered was signed,
-and the Kleinschmidt firm moved to the Morkrum-owned plant in Chicago.
-
- [Illustration: Fig. 10
- Morkrum-Kleinschmidt Corporation No. 14 Start-Stop Typebar Tape Printer
- _Picture through courtesy of Teletype Corporation_]
-
-Bringing together the engineering talent and patents of the two
-companies had an immediate effect toward further progress. The first
-thing the new company set out to do, through consolidation of their past
-efforts, was to perfect a satisfactory start-stop-operated tape printer
-for the Western Union Telegraph Company to use for circuit extension to
-customers who were extensively using the telegraph for immediate,
-written communication. (This was to speed up telegraphic communication
-and eliminate the need for messenger service which had been the custom.)
-The Morkrum company had submitted their start-stop-operated Baudot tape
-printer, and the Kleinschmidt company had proposed the Western Union No.
-22 tape printer in a redesign to start-stop operation. Now, the new
-company was able to combine both plans and as a result came up with
-their first development, a typebar, start-stop-operated, tape printer,
-the No. 14 (see figure 10). In the final design, Howard Krum and his
-production engineers took a large part. After tests and evaluation,
-Western Union’s first order was for 10,000 machines at $317.00 each.
-This amounted to a total of $3,170,000.00. No such quantity had ever
-been heard of before!
-
-It is quite evident that while the two companies were separated, each
-coming up with improved and new designs of telegraph apparatus, there
-was a lack of decision by telegraph companies as to which type of
-apparatus to adopt in expanding their operations, and therefore they did
-not buy in quantity. The largest previous order to the Kleinschmidt
-Electric Company was for 800 No. 22 typebar tape printers for the
-Western Union Multiplex.
-
-At Morkrum-Kleinschmidt more space was needed. The corner property on
-Wrightwood Avenue adjoining the Morkrum plant was purchased, and a
-four-story building was erected.
-
-The design of a telegraph typewriter that would be more efficient and
-require a minimum of maintenance service was the most important project,
-and Morkrum-Kleinschmidt was working with Bell Laboratories engineers
-endeavoring to meet all the requirements of the Bell Telephone system. A
-typebar printer with a stationary printing platen and moving typebar
-printing unit was specified. These requirements were finally met with
-the design of the No. 15 page printer to operate at 60 words per minute,
-and manufacture of this apparatus was started in 1927 (see figure 11).
-The No. 15 page printer became the standard for nationwide
-intercommunicating telegraph service for many years.
-
-In 1926, soon after the No. 14 tape printer was put into service,
-Morkrum-Kleinschmidt received a request from the police department of
-Berlin, Germany, for detailed information, stating that they were
-interested in the purchase of about sixty No. 14 printers. The letter
-asked if Morkrum-Kleinschmidt was represented by an agent in Germany
-whom they could contact. At an executive meeting, Mr. Morton and Mr.
-Krum asked Mr. Kleinschmidt to take care of this matter since his
-company, before joining them, had sold apparatus in some foreign
-countries. After further correspondence with the Berlin police
-officials, Kleinschmidt decided personally to take a No. 14 printer to
-Germany and arrange for a representative there. After visiting and
-conferring with several companies experienced in the telegraph and
-associated apparatus field, a satisfactory arrangement was consummated
-with the C. Lorenz Company, on October 25, 1926, for the manufacture and
-sale of Morkrum-Kleinschmidt equipment in Germany, on a
-royalty-licensing basis. At that time the Lorenz company manufactured
-telegraph and telephone equipment and railway signaling apparatus. Their
-engineering department was under the supervision of Dr. Gerhard Grimsen
-who took the matter in hand for further exploitation toward an
-intercommunicating printing telegraph system, using the No. 15 page
-teletypewriter. Siemens & Halske, the principal manufacturers of
-telegraph equipment in Germany, were also licensed by the
-Morkrum-Kleinschmidt Corporation, on June 1, 1929, with the consent of
-the Lorenz company.
-
- [Illustration: Fig. 11
- Morkrum-Kleinschmidt No. 15 Page Printer
- _Picture through courtesy of Teletype Corporation_]
-
-(As may be seen in the following chapter, it was these licensing
-arrangements which led to the establishment of the TELEX
-intercommunicating teleprinter system in Europe.)
-
-In early 1927 the well-known newspaper publisher, Mr. Frank E. Gannett,
-came to Morkrum-Kleinschmidt, bringing his company’s engineer, Mr.
-Walter Morey, who had heard of various attempts to operate a typesetting
-machine, such as Linotype or Intertype, directly from the telegraph. Mr.
-Gannett said, “We have telegraph typewriters in our news rooms that
-record the news as transmitted from the Associated Press and the United
-Press, and that is fine. Now, why not go a step further and operate our
-typesetting machines directly from the telegraph circuit? If you can
-develop such a device, I will help finance the project.”
-
-Indeed, after some study of the matter, the possibility of devising such
-a system seemed entirely feasible and the development of suitable
-apparatus was turned over to the research and development department. A
-workable plan was soon put together and a separate company, the
-Teletypesetter Company, was organized, with Mr. Gannett joining
-financially. Edward Kleinschmidt was elected president. Development
-proceeded and a complete set of apparatus was set up and publicly
-demonstrated for the first time on December 6, 1928, at one of Mr.
-Gannett’s newspapers, _The Times Union_ of Rochester, New York.
-Teletypesetter equipment was subsequently manufactured for several
-installations. After the Western Electric Company purchased the Teletype
-Corporation in 1930, the Teletypesetter Company was sold to the
-Fairchild Company. Teletypesetter equipment is now in universal use by
-most newspapers and the larger printing companies.
-
-During the period that the United States’ business cycle was on a
-continuous upswing (during the late 1920s), securities sales on the New
-York Stock Exchange were going to constantly higher volume, and the old
-step-by-step stock ticker did not, by large margins, keep pace in
-recording stock share transactions. There was a cry for a higher speed
-stock ticker; in fact, the Stock Exchange officials told
-Morkrum-Kleinschmidt that they would be happy to convert the entire
-system if they could get higher speed.
-
-An adaptation of the five-unit-code, start-stop system seemed the
-solution and the Research and Development department set out to develop
-suitable apparatus. Several ideas were studied and, because of the
-frequent changes from letters to figures, requiring printing in separate
-rows on the tape, a six-unit code was adapted instead in which
-combinations for a figure included the sixth selecting pulse to operate
-the figures print hammer and block the letters print hammer.
-
- [Illustration: Fig. 12
- Morkrum-Kleinschmidt Corporation Stock Ticker
- _Picture through courtesy of Teletype Corporation_]
-
-The Morkrum-Kleinschmidt company was soon able to show the Stock
-Exchange people a stock ticker operating on a telegraph system that
-worked at twice the speed of the step-by-step-operated tickers then in
-use. A speed of 500 printing operations per minute could be obtained,
-thus attaining a one-hundred-percent increase in the transmitting and
-recording of stock quotations on the tape (see figure 12). The Stock
-Exchange ticker service company ordered 15,000 of these high-speed
-tickers and the Western Union Telegraph Company also ordered a quantity
-for their national stock quotations distributing systems.
-
-As business of the combined Morkrum and Kleinschmidt companies went
-along, it was thought that the name “Morkrum-Kleinschmidt Corporation”
-was a pretty big mouthful and that a simpler name more characteristic of
-its products would be better. The name “Teletype” was suggested, and in
-the year 1928 the name change to “Teletype Corporation” was made. The
-exact origin of the word “teletype” is not known but it is no doubt one
-of the abbreviated forms of the words “telegraph typewriter” which were
-used over the years. In literature, in the early 1900s, we find that the
-word “teletype,” in speaking of printing telegraph equipment, and other
-shortened forms, such as “telewriter” and “teletyper,” were used
-interchangeably.
-
-Kleinschmidt’s son, Edward F., who studied electrical engineering at
-Steven’s Institute and at Northwestern University, was employed as
-development engineer by the Morkrum-Kleinschmidt company where he
-assisted in the design of projects at hand, and, during 1929, produced a
-system and apparatus for transmitting and recording printed characters
-by the successive transmission of dots arranged in a pattern to form
-letters. While this system required a higher signaling frequency, it was
-thought to be superior to permutation-code transmission over radio
-circuits where electrostatic interference is experienced, since, in the
-dot pattern transmission, electrostatic interference up to a degree will
-not change the readability of a transmitted letter.
-
-The system was in test operation to prove its efficiency over radio
-circuits where considerable static interference was experienced. Upon
-hearing of this new telegraph for the radio, Mr. R. Stanley Dollar
-became interested in the use of this communicating system for his
-steamship line. There was considerable correspondence in this matter
-during mid-1930, just prior to the sale of Teletype; however, neither
-AT&T nor Western Electric was interested in further promoting this new
-radio telegraph, so the matter was dropped.
-
-Business activities of Teletype Corporation were now growing rapidly and
-with good profit. The capital structure of 10,000 shares was wholly
-inadequate, so by a 15-to-1 stock dividend the capital structure was
-raised to 150,000 shares, and dividends on an annual basis of $12.00
-were paid.
-
-The successful development of apparatus for different applications
-useful in the telegraph field was largely due to the close cooperation
-between the research-development and the manufacturing departments of
-the organization. Howard Krum had expert engineers and designers in his
-department, Kleinschmidt brought his leading engineers and designers
-from the Long Island City plant, and there was a definite spirit of
-cooperation all around.
-
-To quote again from the _Fortune_ magazine story:[10]
-
- As the years up to 1925, when the Kleinschmidt-Morkrum merger took
- place, were wanderings in a profitless desert, so the years from 1925
- to 1930 found the teletype in a land of milk and honey. Mr. Morton,
- however, was inclined to think that a company which had only two or
- three major customers is not strongly placed. Furthermore (and by the
- spring of 1930), at least one of those customers was actively in the
- market as a Teletype purchaser. This buyer was Colonel Sosthenes Behn,
- whose International Telephone & Telegraph Co. includes Postal
- Telegraph at home in addition to many communication and manufacturing
- companies abroad. With Colonel Behn wanting to buy and Mr. Morton
- wanting to sell, negotiations rapidly proceeded to a point at which
- Mr. Morton, at least, thought the deal was almost concluded. But while
- Mr. Morton and the Colonel were discussing the prospective
- acquisition, into the Colonel’s office walked a man who has no other
- place in this story except that he happened to interrupt at this
- moment. As this gentleman was introduced, he asked whether Mr. Morton
- were related to Joy or Paul Morton. When Mr. Morton admitted that they
- were his father and uncle, the man turned to Colonel Behn and said in
- jest: “Better watch your step. That’s a smart family.” Only Colonel
- Behn knows whether he gave that remark any weight, but the point is
- that the negotiations suddenly collapsed, and that the visitor’s
- remark about the smart family still lives vividly in Mr. Morton’s
- memory.
-
- This setback was not a setback at all to such a negotiator as Mr.
- Morton. Two months later, in May, 1930, you find him walking into the
- office of Clarence G. Stoll, vice president of Western Electric, A. T.
- & T.’s manufacturing subsidiary. This time there had been no
- preliminaries. Mr. Stoll rose from his desk and said: “Good morning.
- What can I do for you?”
-
- “Do you want to buy Teletype?”
-
- “Is it for sale?”
-
- “Yes, at a price.”
-
- “All right. Let’s get down to business.”
-
- They got down to business on the spot, and they remained at it for
- three solid days in Mr. Stoll’s office. The agreement as reached
- called for A. T. & T. to pay off the preferred stock of Teletype,
- 13,979 shares callable at 105, and to give one share of A. T. & T. in
- exchange for each common share of Teletype. The A. T. & T. shares were
- worth about $200, so the price came to upwards of $30,000,000—plus, of
- course, the $1,467,795 for retiring the Teletype preferred.
-
-It should be noted here that this deal to take over Teletype on a
-share-for-share basis was exclusive of foreign patent rights but did
-include patent rights in Canada and Mexico.
-
-The sale to Western Electric was closed on September 30, 1930. Mr. Stoll
-of that company was made president. Howard Krum continued on as vice
-president and was a leader in developing a number of commendable
-devices, including a system for transmitting messages in scrambled,
-untranslatable code form and receiving such scrambled code in perfect
-message form. Mr. Morton was retained as consultant. Edward Kleinschmidt
-made an arrangement to do development work for the new organization in a
-laboratory of his own, assigning all inventions to the Teletype
-Corporation (see page 50).
-
-After Kleinschmidt left Teletype, his assistant, Albert H. Reiber,
-carried on as head of Research and Development for a short while before
-his untimely death. In the meantime, Walter J. Zenner had advanced and,
-in 1935, became Department Chief and later Vice President in Charge of
-Research and Development. Under Zenner’s direction a number of new
-devices in the teleprinter field were developed, including
-ultra-high-speed tape-perforating and tape-controlled transmitting
-devices, as well as a high-speed stock ticker operating at 900
-characters per minute (introduced in 1964) to replace the earlier
-Morkrum-Kleinschmidt ticker which operated at 500 characters per minute.
-Some 94 patents were issued in his name, which have contributed greatly
-to the growth of the Teletype Corporation.[11]
-
-On May 15, 1940, Howard Krum and Edward E. Kleinschmidt were both
-honored by The Franklin Institute and awarded the John Price Wetherill
-Medal, each one “For his Part in the Development of a Successful
-Electrically Operated Duplicate Typewriting Machine Now Known as the
-Teletypewriter,” (Quoted from the medal certificate.)
-
- [Illustration: Teletype Corporation’s new Model 33 Automatic

-
-Howard Krum later also received an award as Modern Pioneer from the
-National Manufacturers Association. Edward E. Kleinschmidt, on April 19,
-1958, was awarded the honorary degree of Doctor of Engineering at the
-Polytechnic Institute of Brooklyn.
-
-To continue: After the sale of patent rights in Canada, Mexico, and the
-United States to Western Electric, there remained the European and other
-foreign patent rights still with the original Morkrum and Kleinschmidt
-investors. The International Telephone and Telegraph Company wanted
-these rights, and, after negotiations in New York, a price was set for
-their purchase through the Creed Company in London, then owned by IT&T.
-Edward Kleinschmidt was sent to London in 1930 to close the deal. Some
-changes to the sales contract were requested by Creed which kept the
-cables busy by Kleinschmidt in asking for approval from A. T. & T. and
-Western Electric lawyers. Finally, upon all-around approval, the
-contract was signed at the previously-agreed-to price of one and a
-quarter million dollars.

- CHAPTER 5
- Teletypewriter Intercommunication Expands
-
-
- _TELEX_
-
-As a result of the acquisition of patents of the Morkrum-Kleinschmidt
-Company by the Lorenz company, Siemens & Halske, and, later, the Creed
-company in England, all of which we have discussed briefly,
-teletypewriter intercommunicating expanded rapidly. In just a short
-time, through the cooperation of these companies, it spread over all of
-Europe and was named TELEX (_TEL_eprinter _EX_change Service).
-
-Dr. Gerhard Grimsen of the Lorenz company, in a letter to Edward E.
-Kleinschmidt, dated July 11, 1962, states, in part (slightly edited):
-
- The story of printing telegraph apparatus using an equal length code
- in the Lorenz Co. commences in 1927 with the acquisition of the most
- important patents of the Morkrum-Kleinschmidt Co.
-
- Before then, the Lorenz people were busy in manufacturing Morse
- apparatus and delivering exchange tickers which used the Hughes code.
- The transmitter had a piano keyboard, the receiver was a page printer
- with a moving type wheel.... The biggest network of this kind was
- installed in the Berlin Police service (with one transmitter and about
- 300 receivers). The connections between the headquarters and the
- substations were built by using guttapercha cable lines owned by the
- police administration. This broadcasting network was erected around
- 1907. By 1927 the cables had aged, by normal corrosion, to such a
- degree that instead of 110-volt double current transmitting voltage,
- little by little, up to 220 volts was necessary for a fairly
- satisfying operation. Also, the maintenance of the apparatus became
- more costly.
-
- This was the situation when some communication experts of the police
- and the post administration made the first studies about the newest
- telegraph technique in the U. S. A.... They found that the start-stop,
- five-unit tape printer, the Model 14, developed and manufactured by
- the Morkrum-Kleinschmidt company, would be the best instrument to
- replace the old ones in the police service as well as in the telegraph
- business of the German post administration.
-
- Of special importance to the police service was the fact that by
- introducing this apparatus, it was not necessary to build a new
- network because now it became possible to rent normal telephone lines
- using single current, 40-milliampere, 60-volt current only.
-
-Siemens and Halske engineers, in 1925, had designed a teleprinter using
-the five-unit-code, start-stop principle. This was manufactured and
-improvements added, including the new start-stop method developed by
-Morkrum-Kleinschmidt. The Creed company, which had started manufacture
-of start-stop teleprinters before 1930, having purchased several Morkrum
-printers before the consolidation of that company with the Kleinschmidt
-company, also designed a teleprinter for the new five-unit-code,
-start-stop system.
-
-In another write-up, Dr. Grimsen states that after the Siemens company
-came into the picture, a fully automatic teleprinter network was started
-in 1933 with a trial installation between Berlin and Hamburg for about
-forty private subscribers. The results were so encouraging that the
-German Reichspost continued the work, and five years later the TELEX
-system contained about 10,000 subscribers.
-
-TELEX service was introduced in Great Britain in 1932 and was worked
-over the telephone network, using a single-tone voice frequency carrier
-signal which was keyed on and off by the teleprinter transmitter. (From
-Freebody’s _Telegraphy_.)[12]
-
-Interconnection for TELEX service was made by dialing a subscriber as in
-telephone operation. TELEX directories then, as now, gave the call
-numbers of subscribers. Types of answerback devices were designed in
-both England and Germany which finally developed into an arrangement
-whereby the calling subscriber would, after dialing a number, press a
-special key, the shifted D key—named the “Who-Are-You?” button—which
-would cause the transmission of a signal code automatically to activate
-the called teletypewriter mechanism into transmitting its TELEX number.
-
-Further apparatus, a device to punch the code in a tape and a
-punched-tape-controlled transmitter, was soon added.
-
-The Siemens company also developed and built completely automatic
-switching equipment for the TELEX system which is used by many telegraph
-administrations.
-
-Through the cooperation of the companies who were manufacturing
-teleprinters and associated equipment, the many problems that appeared
-were eventually solved to improve the apparatus and bring the TELEX
-system to eventual perfection for worldwide telegraph communications.
-(At the time of this writing, according to statistics, there are nearly
-1,000,000 TELEX subscribers throughout the world.)
-
-One of the problems faced in setting up such a worldwide system was that
-of standardizing the code and operating speed. At the time of
-Kleinschmidt’s stay in London in 1930 to close negotiations with Creed
-for the sale of Morkrum-Kleinschmidt’s foreign rights, he met Mr. Martin
-Feuerhahn of the German Telegraph Administration who at that time was in
-conference with Creed and representatives from the British Telegraph
-Administration as to standardizing on an alphabet and telegraph code for
-international communications. Mr. Feuerhahn argued for the adoption of
-the American Murray alphabet and code, stating that he already had the
-approval and consent of the French, Italian, and Belgian telegraph
-administrations.
-
-Mr. Feuerhahn and Kleinschmidt spent some hours together. After their
-return to their respective countries, Kleinschmidt received a letter
-from Mr. Feuerhahn referring to their talks and stating that he had been
-in correspondence with Mr. Benjamin of Western Union and Mr. Parker of
-Bell Laboratories with regard to code and other pertinent matters of
-standardization so that an International Teleprinter Exchange could be
-extended into the United States. Another letter dated October 10, 1931,
-reviewed the aforementioned standardization search.
-
-The Murray alphabet and 7½-unit code were soon adopted and are still in
-use today in TELEX.
-
-In later years, an association, the Consultative Committee on
-International Telegraph (CCIT—now the CCITT to include the telephone),
-was formed and met regularly to discuss problems and to set operating
-regulations for the TELEX apparatus in an intercommunicating system. The
-CCITT at this writing is still meeting regularly on worldwide
-standardization in both telegraph and telephone communications.
-
-
- _TELEX IN THE UNITED STATES AND TWX_
-
-In the United States, in November 1931, the Bell Telephone Companies
-announced an intercommunicating teletypewriter service, called TWX for
-short (_T_eletype_W_riter e_X_change), by which interconnections could
-be made by a switchboard operator as in telephone service. One of their
-first advertisements named it a “Telephone Typewriter Service, a service
-that typewrites by wire, a method of inter-office communication that has
-the quickness of the telephone, the flexibility of conversation, the
-accuracy of the typewriter, the authority of the printed word, the
-permanency of print.”[13] Tape-punching and tape-controlled transmitting
-apparatus was provided. This service allowed subscribers to carry on a
-typewritten conversation at a charge less than the cost of a telephone
-call, whether to local or to distant areas. The maximum speed of this
-equipment was limited to sixty words per minute.
-
- [Illustration: Telephone Typewriter Service (early TWX apparatus)
- _reproduced by permission of American telephone & Telegraph Co._]
-
-There are approximately 54,000 subscribers to TWX at this writing, and
-the TWX directory gets fatter with each new issue. In 1962 all TWX
-machines were converted to direct dialing operation, making the service
-easier to use. Instead of going through “Operator” by manually typing
-out the call letters of the party being called, one now merely depresses
-the Originate button, listens for the dial tone, and then dials the TWX
-number of the party wanted.
-
-RCA Communications, Inc., was the first to extend international TELEX
-service to Bell System teletypewriter subscribers (1955), enabling them
-to make and receive overseas calls on their domestic TWX machines.[14]
-As stated, the TWX machines were geared for 60-words-per-minute
-operation, whereas the TELEX system operated at 66 words per minute. It
-was therefore necessary for R.C.A. to use conversion apparatus to an
-error-detecting code for overseas radio transmission. This code was a
-seven-unit code, using three marking and four spacing elements, giving
-35 usable combinations. By using a special printer, when a faulty
-combination was received, a special error symbol was printed.
-
-Western Union, in May of 1958, introduced TELEX service between New York
-City and various Canadian points. By 1962 the service had been extended
-to 67 United States cities, and at this writing they expect to serve 180
-United States cities with an anticipated subscriber capacity of many
-thousands.[15]
-
-In addition to domestic service between U. S. cities, subscribers can
-dial automatic teleprinter connections to Canada and Mexico. Also, they
-can obtain direct TELEX connections to other parts of the world through
-the overseas facilities of RCAC (Radio Corporation of America
-Communications), AC&R (American Cable and Radio), and WUI (Western Union
-International). The operating speed of 66 words per minute and also the
-teleprinter keyboard in the U. S. TELEX network conform to international
-standards of the CCITT. This provides complete operating compatibility
-with other TELEX systems throughout the world without the need for speed
-and keyboard translators.[15]

- CHAPTER 6
- KLEINSCHMIDT LABORATORIES
-
-
-As we have seen, Edward Kleinschmidt, upon resigning from Teletype
-Corporation as vice president when it was taken over by Western
-Electric, had agreed to do development work for them, working
-independently but assigning any inventions to the new Teletype
-Corporation.
-
-And so it was that Kleinschmidt Laboratories came into existence.
-Incorporated on March 21, 1931, under Delaware laws, for the immediate
-purpose of doing research and development work for Teletype, the
-principals of the new company were Edward E. as president, and his two
-sons, Edward F. as vice president and Bernard L. as secretary.
-
-Kleinschmidt had earlier proposed a comprehensive and completely
-automatic printing telegraph switching system in which messages are
-automatically routed from the subscriber printer through telegraph
-centrals of the addressee printer under control of address tape
-perforations. Under his development contract with Teletype he continued
-work on the system. Message storage in perforated tape was provided for
-at all central switching points, and an answerback arrangement was
-included in the system by the automatic return transmission of the
-addressee’s number to the sender.
-
-As the research and development work for Teletype continued, the
-switching system was completed, and various other devices of more or
-less importance were developed, with patents assigned to the Teletype
-Corporation. In late 1934 the contract with Teletype expired.
-
-At that time, son Bernard was operating a printing plant in rather close
-quarters in Highland Park, Illinois. The operations of the Laboratories
-had been carried on in rented quarters at the Merchandise Mart in
-Chicago. Seeing that there would be no work for Teletype, it was decided
-to set up working quarters in Highland Park where the family lived.
-Since rented space was not available, a building was constructed on
-Lincolnwood Road in the Braeside section of Highland Park to house both
-the B. L. Kleinschmidt Printing Company and the machinery and other
-equipment of the Laboratories. The Laboratories, now inactive, became a
-personal holding company with 2300 shares to cover a book value of
-approximately $230,000.00 (Kleinschmidt having distributed the major
-portion of these shares to his children and grandchildren).
-
-Son Edward F. turned his thoughts to other fields and carried on
-experimental work in the new building in devices not connected with the
-telegraph. Son Bernard was involved in his printing business. Their
-father’s thoughts lay dormant for a long time, but still there was the
-urge to continue with the telegraph, and a plan for operating a
-five-unit-code selecting mechanism, operating on a progressive stop
-principle to position a typewheel or to select a typebar for printing on
-tape or page, was worked out.
-
-When models of this new plan were completed and operating successfully,
-Edward E. Kleinschmidt immediately thought of Teletype Corporation and
-brought the apparatus to their attention, submitting models and patent
-applications for their evaluation. After numerous conferences and
-correspondence, however, his offer for the sale of patent rights and
-models was rejected. Discouraged, he left the completed models at the
-Highland Park lab and moved to Florida.
-
-During the second world war, son Bernard abandoned his printing
-establishment and started a tool and die shop, using the machinery and
-facilities of the Laboratories as well as space occupied by his printing
-shop. The B. L. Kleinschmidt Company was kept busy building tools, dies,
-and special devices for the war effort.
-
-Through Bernard’s associations he learned that the United States Signal
-Corps needed a light-weight, transportable teleprinter for tactical
-field use, and he asked his father if he could show the progressive stop
-printer to the Signal Corps at their Chicago headquarters. His father,
-in Miami at that time, gave his approval. Two days later, the telephone
-rang in Miami and it was Bernard saying, “Dad, they are interested and
-want you to bring the printer model to Army Headquarters in Washington.”
-Nothing could have pleased his father more!
-
-In February of 1944, Edward E. Kleinschmidt demonstrated a working model
-of his teleprinter in Washington at the office of the Chief Signal
-Officer. Officials of the Signal Corps were greatly interested in the
-unit, not only because of its extreme lightness and small bulk, but
-because of the representations that the basic design features of this
-tape printer, exclusive of the printing mechanism, could be incorporated
-in a page-type printer which could be constructed with a total weight of
-approximately thirty pounds. The machine was subsequently informally
-tested at the Signal Corps Engineering Laboratories and found to have
-excellent margins when working without an intermediate relay on very low
-line current, a highly desirable feature in a piece of tactical
-teletypewriter equipment.
-
-The exhibit at Headquarters was successful, and after operative tests at
-the Signal Corps’ Coles Signal Laboratories in Red Bank, New Jersey,
-where approval for further studies was given, the Kleinschmidt
-organization was asked to prepare plans toward a tactical light-weight
-printer for field use.
-
-It should be pointed out that teletypewriters at that time were heavy,
-cumbersome, and intended for use only at telegraph offices or at other
-plant or office fixed installations.
-
-The plans for a light-weight page printer were submitted to the Signal
-Corps as requested and were well received by their engineers. These
-engineers then wrote up specifications detailing their requirements for
-a rugged, light-weight portable set for hand-carrying through jungles
-and swamps, and operable under severe climatic conditions; the
-specifications were submitted to the Teletype Corporation, the Western
-Union Telegraph Company, and to the Kleinschmidt organization. Western
-Union did not take on the development job, but Teletype and Kleinschmidt
-accepted. A contract for the development of a teletypewriter according
-to Signal Corps specifications was closed with both companies in 1945.
-
-The Kleinschmidt Laboratories were not in active operation at this time,
-so the first development contract was closed with the B. L. Kleinschmidt
-Company which was fully equipped to carry on the work. Expert tool and
-model makers were in his employ, some of whom turned out to do well at
-the drawing board and were of great help in working out mechanical
-functions. As a matter of fact, five or six of Bernard’s employees are
-still with the Kleinschmidt Division of SCM Corporation at this writing,
-some having attained supervisory positions.
-
-Edward F. joined his father in further engineering and development work,
-and models of a typebar page printer and a typewheel page printer to
-operate at 60 words per minute were built. Upon evaluation by the Signal
-Corps and Army engineers, a printer with a higher operating speed, up to
-100 words per minute, was demanded. This new requirement meant a
-complete redesign of apparatus, but it was successfully carried through
-and experimental models were submitted by both companies. Thereupon both
-Kleinschmidt and Teletype were asked to build ten printers for field
-tests. This was done, and after extensive field testing, the
-Kleinschmidt-designed, keyboard-operated, 100-words-per-minute typebar
-page printer was accepted, and, by order of the then Secretary of War,
-it was made the standard for the Military, effective on January 1, 1949.
-(This printer was later to be known as the TT-4 tactical page printer,
-the principal component of Teletypewriter Set AN/PGC-1.) (See fig. 13.)
-
-An announcement from the Department of the Army, in a document released
-for publication on February 13, 1949,[16] read as follows:
-
- _Portable Teletypewriter Developed by Signal Corps_
-
- Portable teletypewriter equipment so light that a parachutist can
- carry it on a jump from an airplane has been developed and adopted by
- the Army, promising a major advancement in military communications,
- the Signal Corps announced today.
-
- Weighing but 45 pounds, compared with current field equipment that
- weighs 225 pounds, the new portable teletypewriter is but one-fourth
- the size of the old, has 300 fewer parts, is considerably stronger and
- consequently requires far less maintenance. The new equipment is
- capable of transmitting and receiving messages 66 per cent faster than
- existing types and will operate on both wire and radio circuits. It is
- waterproof and should it be used in amphibious operations, could be
- floated onto a beach.
-
- The development is the fruition of a 20-year-old project that did not
- get under way in earnest, however, until World War II was nearly over.
-
- Because of its light weight, the new teletypewriter can be used much
- closer to the front lines than has been the case. During World War II,
- teletyped messages could go only as far forward as a division
- headquarters. How much farther forward the new equipment can be used,
- will be determined in forthcoming field tests.
-
- The portable teletypewriter was developed by the Signal Corps
- Engineering Laboratories at Fort Monmouth, New Jersey, through a
- research and development contract with Kleinschmidt Laboratories,
- Incorporated, of Highland Park, Illinois.
-
- There are three components to a complete field unit: the
- teletypewriter itself, weighing 45 pounds; a power unit, and a case of
- accessories. The three together weigh 116 pounds. All units are
- waterproof, both to permit flotation in amphibious activities and to
- provide complete protection from weather. One man can carry the
- teletypewriter itself, while two men can carry all three units.
-
- The field teletypewriter in current use weighs 225 pounds and—if a
- vehicle is not available—requires four men to carry it. With power
- unit and accessories, present field equipment totals more than 400
- pounds and requires seven men to carry it.
-
-While development work for the Signal Corps was progressing, Bernard
-kept busy managing general operations and Edward F. took hold in the
-general design and devised important features that were patented in his
-name.
-
-Bernard died in March, 1948. However, development work went along with
-the B. L. Kleinschmidt facilities until 1949, when a production order
-for 2,000 teleprinters, conforming to the now approved Kleinschmidt
-design, was to be placed. Now that Bernard was no longer there to take
-over business details, and as a certain amount of basic capital was
-needed to operate a production establishment, arrangements were made to
-transfer Bernard’s equipment to Kleinschmidt Laboratories which
-thereafter closed a contract to manufacture the required quantity of
-teleprinters now designated as the TT-4 telegraph typewriter.
-
-Kleinschmidt senior, now seventy-four, was not eager to take over the
-management of production activities, and while manufacturers in the
-office equipment and radio field were ready and anxious to take on the
-manufacture of these new teleprinters, he sought to keep the future of
-this new development with the Kleinschmidt Laboratories—now owned by all
-members of his family. His son-in-law, Emerson E. (Bud) Mead, was
-operating a manufacturing plant, producing electrical control devices
-quite successfully, so, “Why not ask Bud, then Secretary of Kleinschmidt
-Laboratories, to take over? He could no doubt sell the Mead company at a
-profit.” Bud did find a buyer for his company and he was then made vice
-president of Kleinschmidt Laboratories; later, when Edward E.
-Kleinschmidt turned over full management to him, Mead became executive
-vice president.
-
-The immediate problem at the Laboratories was to find manufacturing
-space. The first thought was to rent, but then there would be no room to
-expand should larger orders follow, and this could be expected since
-Kleinschmidt teleprinter apparatus was now made standard equipment for
-all U.S. Armed Services. Upon further investigation, Bud Mead found a
-plot in Deerfield, Illinois, facing County Line Road, consisting of
-thirteen acres, which could be purchased at a reasonable price. This
-area would give plenty of building room and space for parking cars.
-Kleinschmidt Laboratories’ first building, 200 × 150 feet, was soon
-erected.
-

-Kleinschmidt Laboratories, Inc. AN/FGC-20 Fixed-Station Teletypewriter Set]
-
-Preliminary work toward manufacturing, drawings, ordering of production
-machinery, special tools, standard parts, and other items was carried on
-at the Braeside laboratory.
-
-The efforts of all of the people of the Kleinschmidt organization,
-working with great enthusiasm and wonderful cooperation, sometimes
-around the clock, were rewarded when on April 17, 1950, preproduction
-samples of light-weight teletypewriter sets were delivered on schedule
-to the Signal Corps in Fort Monmouth for approval and acceptance.
-Immediately upon receipt of their approval, production began on the
-contract awarded in June of 1949.
-
-Kleinschmidt Laboratories subsequently received contracts and built
-thousands of their teleprinters, including the filling of orders for the
-AN/FGC-20 fixed station teleprinters (see fig. 14).
-
-Later, the Laboratories, together with the Automatic Electric Company,
-then of Chicago, now of Northlake, Ill., designed and built switching
-apparatus and set up high-speed, 100-words-per-minute, automatic
-teleprinter switching centers for the Military. These systems had trunk
-switching controls located at key distributing points in the United
-States and abroad, interconnected by microwave circuitry.
-
-As further orders for teleprinters and associated equipment came along,
-manufacturing facilities were expanded into more building area;
-additions to the first unit brought that building to 200 × 500 feet.
-Another building, 250 × 350 feet, of special design to house belt-line
-apparatus assembly and parts storage, also testing, inspection, and
-shipping, was erected in 1958.
-
-In August, 1956, Kleinschmidt Laboratories merged with Smith-Corona
-Inc., on an exchange-of-shares basis, which eventually gave Kleinschmidt
-Laboratories’ shareholders 60 shares of Smith-Corona (later Smith-Corona
-Marchant Inc., and then SCM Corporation) stock for one share of
-Kleinschmidt Laboratories’. Bud Mead was elected a director and a member
-of the executive committee. Later, he became vice president of
-operations. When Smith-Corona merged with Marchant Calculators, Inc.
-(June, 1958), he was made executive vice president; then, in October of
-1960, he was named president of Smith-Corona Marchant Inc. (now known as
-SCM Corporation).
-
-Kleinschmidt, as a Division of SCM Corporation, continues to supply the
-Military and also commercial users with teleprinter equipment. The
-conclusion of this chapter tells briefly the direction the Kleinschmidt
-Division is going in the printed communications field.
-
-Before the Kleinschmidt 100-words-per-minute teleprinter was put into
-service on intercommunicating circuits, the operating speed on standard
-circuits had been limited to 60 words per minute. Noting this important
-change in operating speed, other manufacturers had to redesign their
-teleprinter equipment to meet the new 100-words-per-minute speed.
-
-Teletype Corporation came up with a new design, the No. 28, in which all
-the type pallets are moveably mounted in a rectangular box that is
-positioned to move a selected type pallet into printing position by a
-system of levers operated in aggregate motions under control of the code
-selecting mechanisms (fig. 15). When so positioned, a print hammer
-strikes the type pallet to print the character.
-
-Creed, in England, later brought out a new design, their No. 75, using a
-segmented typewheel having four rows of type faces. The typewheel is set
-in the selected printing position by a lever and linkage system
-operating in aggregate motion under control of the code selecting
-mechanism. To print the selected character, the typewheel is struck
-against the printing paper (fig. 16).
-
-Siemens and Halske, in Germany, produced their No. 100, a redesign of
-the No. 15 Teletype, using lighter and faster moving parts for operation
-at 100 words per minute. Among other improved features were a type bar
-shift to replace the platen shift for printing letters or figures, and a
-two-color ribbon which is automatically shifted to print in red or black
-to distinguish between sent and received messages—a feature of
-convenience in TELEX communication. The Siemens No. 100 was designed
-especially for the TELEX system, operating at 66 words per minute, where
-it is used extensively (fig. 17).

-
-The Kleinschmidt printer, designed to operate at 100 to 150 words a
-minute, employs a new method for operating a typebar printing mechanism,
-comprising a type basket movable across the printed page and carrying
-the required set of type bars. Each type bar has a connected push rod
-extending to the rear of the type basket and is made operative to cause
-printing when a rotating finger, selectively positioned by a coded stop
-cage, is struck against the push rod. To meet the requirements of the
-Military for a teleprinter operable in any angular position, the letter
-spacing and carriage return with deceleration to the stop position is
-under positive control of the motor drive.
-

- Military)]
-
-In 1948, scientists at Bell Telephone Laboratories, engaged in
-semiconductor research, announced the birth of their famous brainchild,
-the transistor. Now the little transistor and his friends, the diode and
-advanced techniques in electromagnetic inductive devices, have gradually
-taken over in the communications field, permitting startling speed
-increases and changes in equipment design.
-
-In the 100-words-per-minute teletypewriters, the permutation code
-equivalent of the character to be transmitted or received was at some
-point “set up” mechanically by positioning levers or vanes. The inertial
-properties of these mechanical parts placed low-level limitations on the
-operating set-up speed. By using the binary code and electronic
-switching circuits, the set-up time has been reduced from milliseconds
-to microseconds, making higher speeds more easily obtainable. Also,
-electronic approaches to printing on page or tape have contributed to
-the speed-up of telegraph receiving devices. Now, both tape and page
-devices are available at operating speeds up to 10,000 words per minute.
-
-Thanks to the Bell System, also, is the development of Data-Phone
-service, started in 1958. Data-Phone makes use of all the telephone
-switching devices and repeating apparatus so that any type of
-communicating system using frequencies within the voice range may be
-used. For such systems the telephone company will install equipment to
-separate the different types of electrical transmission to prevent
-interference. Because Data-Phone enables not only the sound of the human
-voice to be sent over a telephone circuit, but information from a
-teletypewriter or business machine as well, this new use for the
-telephone system has expanded its service to many types of business
-communications. At this writing, the Bell System advertises, “Data-Phone
-‘talks’ 16 times faster than people talk. It can send punched card or
-taped data anywhere—at speeds up to 2500 words per minute.”
-
-While these advances have been taking place, the transistor and its
-companions have made a similar impact in the field of data processing.
-The rapid evolution of computers and other high-speed switching devices
-has generated a need for higher speed equipment to supply input and
-output requirements. The changeover to electronics has realized
-minification, lighter weight, reduction of mechanical parts with a
-corresponding reduction in maintenance, quieter operation, and greater
-adaptability to code and language conversion.

- KLEINSCHMIDT DIVISION OF SCM CORPORATION
-
-At the Kleinschmidt Division where Mr. Emilio J. Cadamagnani, Executive
-Vice President, is in charge, their engineering department, under the
-supervision of Mr. Robert L. Kearney, is keeping up with the change from
-electromechanically- to electronically-controlled devices. Their new
-Model 311 Electronic Data Printer shown here is an example. Operating at
-speeds from 60 to 400 words per minute and capable of receiving 5-, 6-,
-7-, or 8-level code information in either serial or parallel form, it is
-designed for use in high-speed communications or data processing
-systems.
-
-Also illustrated is still another new Kleinschmidt device, the Model 321
-Automatic Data Set, which includes not only a page printer with keyboard
-but a tape perforator and a tape reader, all compactly mounted in a
-console.
-
-Both the Model 311 and Model 321 are compatible with existing data
-modems, conventional printing telegraph equipment, electronic computers,
-and data processing equipment. This compatibility permits their use in
-on-line or off-line communications and data-handling applications.
-
-More exciting devices may be anticipated in the rapidly moving field of
-printed communications.

- PREFACE
-
-
-Having been associated with the printing telegraph for more than sixty
-years, I have felt the urge to write a rsum of the problems and the
-progress made during my time toward today's wonderful achievements in
-the art of telegraphic communications.
-
-It is interesting to note that of all the old-time electric telegraph
-systems, it appears that only those using the Morse dot-dash code
-invented in 1837 and the permutation code devised by Gauss and Weber in
-1833 (now known everywhere as the Baudot code) have survived today.
-
-Samuel Morse's code, which was modified somewhat in several letter code
-compositions to facilitate its use anywhere in the world, has become an
-audible, easily learned international language, loved by its users
-everywhere. It will no doubt continue to be used for some time to come,
-as long as we have our railroad telegraph operators, radio amateurs,
-police CW systems, certain branches of the Armed Forces, and any others
-who converse in dits and dahs.
-
-The permutation code has taken hold firmly, too. Its use of five pulses
-transmitted in varying combinations of on and off, or positive and
-negative, conditions has wide application in today's printed
-communications systems. As in the Morse system, alphabets for the
-five-unit permutation code system have been modified as to letter code
-compositions for international correspondence. The permutation code uses
-the powers of two in progressively selecting a letter printing position.
-
-The binary code uses the same selective stops by yes or no designation
-in a system of counting by the powers of two. It is used where larger
-groups of yes or no positions are required, as in data processing and
-computer systems.
-
-This writing, then, is a bit of history that will put together the
-constructive developments that brought about the present era of the
-worldwide, telegraphically-transmitted printed word.
-
-I wish to acknowledge with great appreciation the informative material
-sent to me by my friends, both here and in foreign lands, who are
-associated with the telegraph industry.
-
-For assembling information we have gathered from various sources and for
-the most helpful assistance given me in writing this story, I also want
-to thank my secretary, Mrs. Doris Pompilio.

- PRINTING TELEGRAPHY ...
- A NEW ERA BEGINS
-
-
-
-
- CHAPTER 1
- Introduction
-
-
-It is a major effort today to keep pace with the rapid advances in the
-field of printed communications. Hardly a day passes that we do not read
-of a new development in equipment that is more complex, farther
-reaching, more rapid in operation....
-
-This electrical, or electronic, transmission and interchange of the
-printed word might be said to be an evolvement of the old printing
-telegraph systems. Such systems, over the years, while not so rapidly as
-today, were also improved upon, modified, speeded up, but could be used
-only in the point-to-point transmission of messages.
-
-While the railroads had been using the Morse code system (key and
-sounder) satisfactorily, they would have preferred a system whereby a
-printed record could be obtained. In the industrial world, too, there
-was need for a businessman's printing telegraph--a means to type out
-messages, directly and interchangeably, to far-off associates. And there
-was always that dream, starting with the earliest telegraph
-experimenters, of being able to correspond instantly with one another
-anywhere in the world. Indeed, the need for all this had been known for
-many years, but not the way.
-
-It was after the turn of the century that telegraph engineers began in
-earnest to think about a system of telegraphy that would permit direct
-intercommunication by the printed word, and direct circuit connection to
-any outlying subscriber as in the telephone communication system.
-
-Up until then, apparatus for transmitting telegrams, such as that of
-Wheatstone & Cooke, Morse, Hughes, Barclay, etc., also the step-by-step
-stock tickers and bulletin printers, used various types of
-code-signaling devices in which the code varied in length as to the
-transmission of more frequent or less frequent letters.
-
-Now in order to provide a practical telegraph system permitting the
-interconnection of apparatus throughout the world, the first basic
-requisite is a standard signaling code; this code, moreover, must be of
-such nature as to use the simplest form of electrical signaling (such as
-make and break signals, or positive and negative signals), and the code
-should be of equal length for all characters.
-
-The permutation code, where combinations of five plus and minus pulses
-will give thirty-two selective positions, was suggested as far back as
-1833 by Gauss and Weber. Whitehouse, in 1854, and Barnett, in 1860,
-experimented further, using the permutation code to operate a recording
-mechanism. However, no practical means for actually printing letters and
-figures was found until 1882 when Jean Maurice Emile Baudot designed a
-multiplex system to permit the transmission of four messages in each
-direction over a single line circuit. Later, Baudot designed a tape
-printer in which the selecting and printing mechanisms comprised an
-ingenious arrangement of cooperating parts, including a rotating
-typewheel associated with a coded combiner wheel and five stationary
-elements selectively movable to received code positions, each element
-having an extending finger to be brought into contact with the periphery
-of the coded combiner wheel upon the completion of a selective code
-setting. When the code combination of the set fingers matched a code on
-the wheel, a print roller was released to press the recording tape
-against the typewheel and print the selected letter.
-
-Although the Baudot Multiplex was used extensively in Europe, engineers
-and inventors in the United States had not produced a practical 5-unit
-permutation-code teleprinter system. They were constantly searching for
-a unit code system requiring a minimum number of electrical impulses to
-operate a telegraph printer. Various types of relay systems using
-distinctive signal pulses were proposed. A three-unit-code system that
-showed promise, and did not require synchronism, used four different
-electrical pulse conditions: a high voltage positive or negative pulse,
-and a low voltage positive or negative pulse. Records show that many
-inventors played with this code and that John Burry, C. L. Krum, G. A.
-Cardwell, and J. C. Barclay, among others, built operable equipment
-using such a code arrangement. The following excerpt from Cardwell's
-patent No. 905,497 of December 1, 1908, may be of interest. It describes
-the code arrangement of four different line conditions in three signal
-groups to produce 36 different code combinations.
-
- In order to energize the controller magnets in proper sequence to
- position the type wheel for printing a desired letter, a predetermined
- code or system of sending in the impulses is essential. In an
- instrument constructed by me in accordance with the present invention
- I have used the following:
-
- 1-2-1 letter space
- 1-2-3 carriage return
- 1-2-4 line space
- 1-3-1 type wheel shift

- impulses through the relay contacts 1, 2, 3 and 4.
-
-Cardwell's backers formed the American Telegraph Typewriter Company and
-sold shares, claiming a great profitable future for their apparatus. A
-few printers were built, but, on extended service tests, the
-high-low-voltage feature proved to be impractical and the company
-folded.
-
-J. C. Barclay of the Western Union Telegraph Company designed printing
-apparatus and perforated tape transmitting equipment for this type of
-system, but, after limited use of the high-low-voltage principle, he
-changed this feature to long and short pulses with discriminating
-relays. With later improvements, this system was put into service on a
-number of Western Union message circuits.
-
- _Note:_ Today, in the 1960s, the techniques of frequency division and
- electronics could be used for transmitting three different line
- conditions from a group of four different frequencies. In such a
- system, synchronism between send and receive terminals, or the
- start-stop method to control correct timing, is not needed. The
- transmission of any selected group of three, when received in
- succession at a teleprinter, will cause printing of a letter when the
- third receiving relay completes a circuit to the selected printing
- magnet. Transistor circuits with associated control elements could
- replace the relays.
-
-Telegraph companies in the United States were mostly using the Morse and
-increased its efficiency through development of quadruplex operation and
-high-speed transmission systems. However, the quest for a more efficient
-printing telegraph system persisted and various types were proposed and
-tried. All made use of codes that were impractical for
-intercommunicating systems and, while some were used in message service
-by the telegraph companies, they did not appear to have any great
-advantage over the Morse telegraph.
-
-In 1911, Western Union began investigating systems used in Europe. The
-first to be tested was the Creed, a system for transmitting and printing
-Continental or Morse code signals at high speed. After observing several
-other systems, the Murray Multiplex, an improved and modernized version
-of the Baudot Multiplex, was found to show better operating features
-and, due to the use of the five-unit permutation code, more efficient
-use of telegraph lines.
-
-By agreement with Donald Murray, and with his cooperation, the so-called
-Western Union Multiplex was developed, using Murray's phonic wheel drive
-and synchronous correction. Western Union engineers designed tape
-transmitters and an autocontrol device for transmitting service signals.
-A keyboard-operated, five-unit-code, tape punch was supplied by the
-Morkrum Company. A page printer, which was later converted to print on
-gummed tape, was supplied by the Kleinschmidt Electric Company. The
-Western Union Multiplex was effective in increasing operating efficiency
-and came into extensive use throughout the system.
-
-From that time on, development of the Baudot permutation-code printing
-telegraph apparatus was furthered by various companies, such as Bell
-Laboratories, Western Electric, the Morkrum Company, the Kleinschmidt
-Electric Company, as well as the companies of J. E. Wright, L. M. Potts,
-and others.
-
-It appears that all of these inventors experimented with the idea of
-operating all transmitting and receiving apparatus at identical speeds
-to transmit a five-unit-code combination by first transmitting a pulse
-to start both transmitter and the distant receiver at the same time.
-Synchronous operation was obtained by electric motors equipped with
-governors to maintain correct speed; some used tuning-fork-controlled
-impulse motors. A system of five relays with progressive contact
-arrangements to cause cascade operation was also used to provide correct
-timing. Later, when correctly-timed, 60-cycle alternating current became
-available (see page 27), synchronous motors did the job.
-
-Teleprinter apparatus using this synchronous method worked very well for
-point-to-point transmission as was used by the telegraph companies and
-news-distributing organizations to carry local traffic. It did not,
-however, solve the sought-for plan for a teleprinter intercommunicating
-system. When attempts were made to connect printers at different distant
-points in a telegraph intercommunicating circuit while using the
-synchronous principle, false reception and printing errors would occur,
-due to variation in line circuit conditions and to a variation of the
-mechanical start operation at outlying teleprinters. This required
-frequent overline adjustment to keep the connected apparatus in phase.
-
-The following is an excerpt from a patent application of Dr. Louis M.
-Potts (later to become research engineer for the Morkrum-Kleinschmidt
-Corporation), filed June 17, 1909, giving his idea for achieving a
-teleprinter intercommunicating system on the synchronous principle. Dr.
-Potts was a very capable telegraph engineer. His early association was
-with the telegraph system of the Rowland Telegraphic Company which had
-limited use in the early 1900s.
-
- In those synchronous telegraph systems wherein the sending and the
- receiving commutator brushes constantly rotate, it is necessary to
- adjust these brushes so that they will approximately simultaneously
- engage corresponding segments. To effect this adjustment there is
- usually provided a special device embodying an additional segment on
- each commutator, and the adjustment consists in causing the brushes to
- arrive approximately simultaneously on this segment at the two ends of
- the line. Such adjustment is known as "finding the letter" and has to
- be made every time synchronism has been interrupted. According to the
- present invention, the necessity of providing additional means for
- performing the so-called operation of "finding the letter" is rendered
- unnecessary, since the transmitting and receiving commutator brushes
- at the two ends of the line start up afresh as it were for each
- signal.
-
-In a later patent application, filed October 11, 1913, Dr. Potts stated:
-
- This machine has also the advantage of being able to operate with a
- very short code. In order to adapt it to Morse circuits, it should be
- capable of operating with a code at least as short as the Morse code.
- In the present machine, I preferably employ a five unit code which,
- together with the starting impulse and the lag between signals, is
- actually shorter than the Morse code. Counting the five code impulse
- periods, the starting impulse period and the period of lag between
- impulses, each signal in my case, may be considered in comparison with
- the Morse code as being seven units long, whereas the Morse code is
- 8.5 units long. The average signal being shorter than the Morse, the
- delicacy of adjustment will be less and the distance of operation
- greater than a Morse telegraph for the same rate of transmission in
- words per minute.
-
-Dr. Potts, however, still depended on like synchronous operation at both
-terminals, and dual start, so he did not have the answer after all!
-
-John E. Wright, who in the 1890s designed and built step-by-step
-printing apparatus, including the Wright-Negron bulletin printer, also
-turned his thoughts toward the five-unit permutation code for printer
-operation and built several variations using the synchronous principle.
-The Superintendent of Telegraphs for the Delaware, Lackawanna and
-Western Railroad thought well of Wright's apparatus and placed some in
-operation. But, here again, reliable operation could be maintained only
-in point-to-point operation. As will be noted in Chapter 2, Mr. Wright's
-patents were purchased by the Kleinschmidt Electric Company in 1922.
-
-A paper issued by Siemens-Halske of Germany in January of 1917[1] states
-that the Siemens Pendel Telegraph "is among the forerunners of the
-eventual worldwide start-stop system for intercommunication by the
-printed word." The following excerpt translated from that description
-briefly explains the operation:
-
- The Pendel Telegraph uses the five-unit permutation code to select
- characters, and operates on a start-stop principle. It is intended for
- station-to-station, one-way operation, the line current normally being
- closed to the positive side of the line battery. Transmission is under
- control of a keyboard with keys arranged as in a typewriter. Upon the
- depression of a key, the line battery is reversed, thereby
- transmitting a negative pulse to line which effects the start of both
- transmitter and receiver at the same time. Thereafter,
- five-code-combination pulses are transmitted, followed by positive
- current to line, thus restoring the circuit system to a normally
- closed line condition.
-
- The name "Pendel Telegraph" would make one think that the timing of
- the transmitter and receiver were under control of a swinging
- pendulum. This is not the case. However, it does have a plan for
- simulating the action of a pendulum by an arrangement of springs and
- semi-rotating weights to effect synchronism for each printing cycle;
- and energy is derived from a motor which intermittently winds a power
- mainspring to an even tension. This arrangement is started in
- operation at both terminals at the same time and provides isochronal
- motion at both transmitter and receiver for each transmitted
- character. Due to multiple operations of the springs and weights used
- to provide synchronous action, the operating speed is limited to four
- or five letters per second.
-
-In England, too, there was work being done along these same lines. Mr.
-H. H. Harrison, who is so well known for his contributions over the
-years in the telegraph field, devised printer apparatus using the
-five-unit code which is described in Herbert's _Telegraphy_,[2] as
-follows:
-
- The instrument is provided with a Baudot 5-key keyboard, and has a
- step-by-step distributor which is mounted inside the casing. The
- standard Baudot alphabet is used, but each letter or character is
- prefixed by a positive starting impulse. Every time a key is depressed
- a universal bar is actuated which closes contacts giving the starting
- impulse and the distributors at both ends of the line step through six
- spaces. The combiner is of the electrical type invented by Baudot, and
- is similar to that used in Siemens' new automatic printing telegraph.
- Five relays of the class used for telephone purposes are set at the
- receiving end, according to whether some of the stepping impulses are
- positive or negative. The distributor is a trunk hunting switch as
- used in automatic telephony, and consists of a ratchet wheel and
- stepping electromagnet. On the shaft of the ratchet wheel is fixed a
- wiper which sweeps over a semi-circular bank of contacts in response
- to the stepping impulses. Two-way working is secured by means of the
- differential balance.
-
- (The article ends with the statement that a typewriter keyboard is
- being constructed to replace the five keys.)
-
-It appears that all of these telegraph engineers and inventors
-envisioned a start-stop system and experimented with the idea of
-operating all transmitting and receiving apparatus at identical speeds
-by inserting a start signal before each group of letter code signals, to
-start both transmitter and distant receiver at the same time, and a stop
-condition between code groups.
-
-In the following chapters will be shown the contributions made by both
-the Kleinschmidt and the Morkrum companies in the printing telegraph
-field, and finally their joint efforts which were to lead up to the
-establishment of that now worldwide intercommunicating system, the
-TELEX.

- CHAPTER 2
- KLEINSCHMIDT
-
-
-Edward E. Kleinschmidt's first direct contact with telegraph apparatus
-was during his employment as a young man, in 1893, by John E. Wright,
-whose firm had developed and was then manufacturing printing telegraph
-equipment known as the Wright-Negron bulletin printer for the Havas News
-Agency in Paris. These printers operated on the step-by-step principle
-at 30 words per minute. (To attest to their ruggedness, as late as 1951
-some of these machines were reported to be still in use!)
-
-Five years later, in 1898, Kleinschmidt started an experimental shop at
-122 Fulton Street in New York City. A sign over the door read,
-"Inventions Developed," and he did experimental and developmental work
-for various customers (individuals as well as companies--including
-Western Union) on a time-and-material basis. In the beginning he had a
-project of his own going--a facsimile telegraph system. He submitted the
-system to Western Union in 1900 with the suggestion that it might be
-valuable for customer services, since a customer could write his
-telegram in longhand and insert the written message in the transmitting
-unit for transmission in facsimile to the telegraph central. The idea,
-however, was rejected. At that time the photoelectric cell for scanning
-the written message and electronic means for amplifying signals had not
-yet been developed; while the apparatus operated quite well over short
-circuits, evidently the time had not arrived for commercial facsimile
-telegraphy.
-
-The first telegraph apparatus job for the shop was brought in by Dr.
-George A. Cardwell, a dentist by profession. It was a partially
-developed printing telegraph using a three-unit code made up of
-combinations of plus-minus-high-and-low-voltage pulses (the code we have
-already discussed). The work for Dr. Cardwell was carried on until 1903
-when a working model was completed. It had a typewheel for printing and
-stops arranged in a circle; magnets under control of relay selection
-were used to set the stops according to the received code combinations.
-This arrangement operated well, and on a test over a Western Union
-circuit from New York to Baltimore it gave satisfactory results. As we
-have seen, however, the code arrangement proved unsatisfactory for
-general telegraphic use.
-
-Many customers came to the experimental shop with every type of idea
-imaginable; vacuum cleaners (The "Vacuna"), elevator signals, some early
-designs for Elmer Sperry's gyrocompass were only a few. Kleinschmidt
-also set up a couple of side-line businesses, one for manufacturing
-automatic fishing reels under the trade name "Kelso," another, the
-Aseptuloid Company, for making vaccination shields (some readers may
-well remember their childhood vaccinations being protected by a bubble
-of celluloid).
-
-Another customer was George M. Seely, who later was instrumental in
-bringing Kleinschmidt's work to the attention of Charles B. Goodspeed
-and W. S. Moore (they were to become his financial backers--see page 14
-). Mr. Seely came to the shop in 1906 with a partially developed block
-system for electric trolley car railways. His plan was to use special
-devices attached to the trolley pole which would cooperate with
-stationary electrical controls at certain fixed points along the road.
-
-After working along these lines for awhile it became apparent that some
-inventive work would be required on Kleinschmidt's part. Seely, in
-addition to time and material, then offered him a retainer for the
-assignment of any resulting patents.
-
-As plans and studies progressed, a number of railway signaling devices
-were developed, tested, and patented. A major item was the development
-of a telephone train dispatching system. A complete set of apparatus was
-exhibited in operation at the American Association of Railroads
-Communications Convention held in Los Angeles in 1910. The company name
-given this venture was the "National Telephone Selector Company,"
-located at 235 Greenwich Street, New York City. The telephone train
-dispatching system was installed on the Long Branch Railroad with 30
-stations connected with dispatcher headquarters at Red Bank, New Jersey.
-Another installation was made on the Baltimore and Ohio Railroad in West
-Virginia, connecting 38 stations with dispatcher headquarters at
-Fairbanks, West Virginia.
-
-Most of the patents assigned to Mr. Seely were eventually sold to the
-Hall Signal Company.
-
-Doing development work for others and assigning patents for a retainer
-did not satisfy Kleinschmidt's ambitions. His interests being mainly in
-the telegraph, he set out to design and build a piece of apparatus that
-the telegraph companies could use. A keyboard-operated perforator to
-punch the Morse code in a tape for automatic transmission at high speed
-looked like a promising subject, since the tape punches in use at that
-time had a three-key arrangement--one each for dot, dash, and space.
-
-Kleinschmidt's first keyboard-operated, Morse-code perforator was
-constructed in 1911 and exhibited to the Western Union Telegraph
-Company. Mr. G. R. Benjamin, their chief engineer, and Mr. Emmett R.
-Shute, a vice president, thought well of the machine and, after testing
-it, gave Kleinschmidt an order for fifty. This order spelled success. To
-celebrate the event, Kleinschmidt invited his brothers, Bernard, Fred
-and William, and their families to a dinner party at a distinguished
-restaurant. Soon thereafter (1913), the Kleinschmidt Electric Company
-was organized, with the brothers as incorporating officers.
-
-The Kleinschmidt Keyboard Perforator came into use by telegraph and
-cable companies throughout the world where Morse, Wheatstone, or Cable
-codes were used to transmit telegrams. It was also used with Western
-Union's Barclay system which had its own code. The device was later
-manufactured by Teletype Corporation under the name "Teletype
-Perforator" and used by the U. S. Government where it served its purpose
-for high-speed Morse transmission during the war period (see figure 1).
-
-In the years 1911 and 1912, the Western Union Telegraph Company, in
-looking toward higher operating efficiency over their trunk circuits,
-decided to test the Creed high-speed Morse and the Murray Multiplex, and
-invited both companies to bring their apparatus to New York. It was on
-this occasion that Kleinschmidt became acquainted with Mr. F. G. Creed,
-who, upon observing the Kleinschmidt keyboard perforator at Western
-Union, was impressed by its performance and said that there would be a
-good market for it in England, especially as a keyboard punch for the
-Creed high-speed Continental-Morse-code system. As a result of that
-conference he asked for ten as a trial order. These perforators were
-shipped to London in due time and gave satisfactory service. The British
-Post Office Telegraph evidently had heard about this new perforator and
-sent a letter to the Kleinschmidt company asking for a demonstration at
-their London headquarters.
-
-Now it happened at that time that Kleinschmidt was extremely busy with
-the development of a five-unit-code typebar printer for the new
-Multiplex--and this was urgent since the first model was to be put on
-competitive test with a typewheel printer submitted by L. M. Potts and
-the Western Electric typewheel printer which was then in use. Therefore,
-he felt he should not lose a month or two in this developmental work for
-a trip to London. So, his answer to this important invitation was that
-he could not personally bring one of his perforators for exhibit but
-that he would ask Mr. F. G. Creed to do so. Mr. Creed agreed and set up
-a formal exhibit for the Post Office engineers; he consequently received
-an order for twenty Kleinschmidt perforators. Further correspondence
-with Creed resulted in an order for one hundred and a request that
-Kleinschmidt come to London the next year (1914) to negotiate a contract
-to supply his keyboard perforators for the Creed high-speed Morse and to
-set up a sales agency with Creed for certain territories.
-
-While in London in the summer of 1914, Kleinschmidt visited the Managing
-Director of the Post Office Telegraph at his office to apologize for
-having had Mr. Creed exhibit the Kleinschmidt perforator instead of
-bringing it personally as had been requested. The Managing Director
-replied that Mr. Creed had indeed given a very good operating exhibition
-of the device and that an order for twenty had been placed with him.
-"However," he added, "you know, we sent you an official invitation and
-expected your appearance with your machine!"
-
-To continue: Upon observing the change in systems at Western Union
-(switching from the Barclay to the Murray Multiplex), the Kleinschmidt
-Electric Company, who had been experimenting in the development of a
-telegraph typewriter, built a receiving teletypewriter for the
-multiplex. It was a magnet-operated, five-unit-code typebar page
-printer, using the Underwood typewriter mechanisms as a basis; and it
-was completed in time for test and evaluation at Western Union in
-competition with the typewheel printers of both L. M. Potts and Western
-Electric.
-
-The Western Electric machine was given the number 1A, Mr. Potts's, 2A,
-and the Kleinschmidt printer was 3A. The final outcome of the tests was
-the selection of the Kleinschmidt model, and the company received an
-order for five machines, to include a spare, to equip the New York
-terminal of a New York-to-Boston, four-channel multiplex system. The
-order was filled in a short time and the machines were put on test.
-
- [Illustration: Fig. 1

- returned to author by a customer after being used thirty years!_)]
-
- [Illustration: Fig. 2
- 3B Typebar Page Printer of Kleinschmidt Electric Company
- _from Museum of Kleinschmidt Division of SCM Corporation_]
-
-Kleinschmidt watched the operation of his machines in service almost
-every day and was continually on the lookout for possible ways to
-improve and simplify the apparatus. The tests ran through to completion
-satisfactorily, and, upon submitting an improved design, numbered the
-3B, the Kleinschmidt Electric Company received an order for one hundred
-typebar page printers. The 3B thereafter became standard apparatus and
-additional orders were placed as the multiplex system at Western Union
-expanded (see figure 2).
-
-Several years later, Western Union efficiency engineers found that, due
-to circuit failures, certain parts of messages would have to be
-repeated. Because this meant retyping the message, they felt, and for
-other reasons as well, that printing the received messages on tape would
-be more economical, since corrections could be inserted without
-repeating the entire message. To meet this requirement, the typebar page
-printer was redesigned for printing on tape. This was accomplished by
-using the same selection controls and operating the typebars to print
-downward on the tape instead of upward against the platen as in the page
-printer. A tape gummer to attach the tape to a message blank was also
-designed. The 21A, later No. 22, tape printer was ordered in quantity
-thereafter.
-
-Seeing the possibility of using their typebar page printer for
-direct-line service, the Kleinschmidt company built a motor-driven
-send-receive unit having a single contact transmitter which operated
-under control of a code-perforated tape to transmit seven signals in
-succession: one start, five code, and a stop signal. The receiving unit
-had a seven-segment commutator, one segment for start, five for code,
-and one for stop, and a rotating brush to pick up and transmit the
-received code signals to the printing unit. This apparatus was installed
-at the United Press for news distribution to their connected newspapers.
-Another set was installed at the Louisville and Nashville Railroad for
-station communications, and still another in New York City at the
-Equitable Life Assurance Society between their downtown and uptown
-offices. In connection with the latter installation, the Equitable
-people asked permission to install the printing apparatus on the
-telephone line and there was objection from the telephone company.
-However, after some consideration they finally agreed that the apparatus
-could be installed but warning that should it create interference with
-the telephone line it would be removed immediately. As it turned out,
-the printer operation over this telephone circuit did not create any
-interference and the apparatus remained in service a long time (figure 3
-).
-
- [Illustration: Fig. 3
- Kleinschmidt Electric Company
- Teletypewriter Apparatus for Direct-Line Service]
-
-The Kleinschmidt Electric Company now began to have financial
-difficulties. Edward Kleinschmidt was borrowing wherever he could. There
-was no large quantity production and evidently his charges for the
-apparatus delivered were too low. At any rate, early in 1917, Mr. Seely
-suggested that he get financial help to carry on and it was here that
-the following gentlemen entered the picture: Charles B. Goodspeed of the
-Buckeye Steel Casting Company; Paul M. Benedict, assistant to the
-president of the C. B. & Q.; Edward Moore, son of Judge Moore of the
-American Can Company; Eldon Bisbee, a New York lawyer; and one of Mr.
-Bisbee's clients, Albert Henry Wiggen, who was then president of the
-Chase National Bank. With their financial backing, the company was able
-to continue with further developmental work on simplified and more
-efficient apparatus. Orders for various types of equipment for the
-Western Union Multiplex and for the Morse code keyboard perforator came
-along, but developmental costs were high and still more capital
-investment was required; Kleinschmidt would then borrow from the Chase
-Bank. Every so often at the Kleinschmidt company's directors' meetings,
-Mr. Holly, cashier of the bank and also a director of the company, would
-state that the Kleinschmidt loan "stood out like a lighthouse," so a
-vote for an additional stock issue was carried and the loan paid.
-
-Along about 1919 the Kleinschmidt company had completed a satisfactory
-keyboard-operated typebar teleprinter for intercommunication systems
-(see figure 4). The Kleinschmidt Telegraph Typewriter, as it was called,
-was installed at the New York City News, the Panama Canal, and at the
-Brooklyn Union Gas Company (fig. 5).
-
-In 1922, Edward Kleinschmidt, having learned that Mr. J. E. Wright had
-discontinued further developments in the telegraph field, proposed the
-purchase of his patents, stating that this acquisition would broaden the
-Kleinschmidt company's patent situation. The proposal was carried, and,
-after negotiations, Mr. Wright's patents were bought for 100 shares of
-the Kleinschmidt Electric Company's common stock.
-
-In 1923, the Kleinschmidt Telegraph Typewriter was exhibited at the 20th
-Annual Business Show in New York and created a great deal of interest.
-In 1924, a complete telegraph system was engineered and set up for the
-Mexican government. (An engineer from Western Union was borrowed to help
-with this job.)
-
-One day, in 1923, after some correspondence with Samuel Samuel & Co.,
-Ltd., through whom the Kleinschmidt company received orders from Japan
-for the Morse code keyboard perforator, the Japanese Telegraph
-Administration sent one of their telegraph engineers, Mr. Y. Okomoto, to
-the company's headquarters to assist in working out a keyboard
-arrangement of Japanese characters for a simplified alphabet consisting
-of 88 characters which the Japanese Telegraph Administration had
-devised. The five-unit code could not be used since only 64 selective
-positions could be had. So the telegraph typewriter mechanisms were
-changed to six-unit-code operation, which worked out very well. The
-Kleinschmidt company, and later Morkrum-Kleinschmidt, received
-continuing orders for the six-unit-code telegraph typewriters.

- CHAPTER 3
- KRUM AND MORTON
- (MORKRUM)
-
-
-Mark Morton, head of the Western Cold Storage Company in Chicago, and
-cold-storage engineer Charles L. Krum, the vice president of the firm,
-entered the telegraph field quite by accident. A young electrical
-engineer named Frank Pearne, in 1902, had some ideas for a printing
-telegraph machine and needed financial backing to carry on his
-experiments. One of his contacts happened to be Joy Morton, the founder
-of the Morton Salt Company. Joy Morton became interested enough to
-become Pearne's backer, and prevailed upon brother Mark to set up a
-laboratory in the attic of the cold-storage plant for Pearne's
-experiments.
-
-It seems that after a year or so, Pearne lost interest in his invention
-and went into the teaching field. He proved to be a very successful
-professor at Armour Tech where he remained until his death.[3] But
-Pearne's work was not in vain, for Charles L. Krum had become intensely
-interested and carried on the work with further inventions of his own.
-Indeed, he filed his first patent application on August 20, 1903, which
-proposed the use of a code comprising four signals: a positive pulse or
-a negative pulse of low voltage, and a positive or negative pulse of a
-higher voltage. Four additional patents were filed, the last in 1906.
-
-C. L. Krum then set about building a machine which was demonstrated in
-1906 and looked promising enough to form a company to further develop
-it. This company was made up of the Mortons (brothers Joy and Mark) and
-the Krums (Charles L. and his son Howard who had just finished college).
-The combination of their names, of course, resulted in "The Morkrum
-Company," which was incorporated in the State of Maine on October 7,
-1907. The charter stockholders were Joy Morton, who shouldered the
-greatest financial burden; Charles Krum; Joy Morton's secretary, Daniel
-Peterkin (he later became an officer of the Morkrum Company); Mark
-Morton; and Sterling Morton (Joy's son, of whom we shall be hearing more
-later on). The working capital of the new company amounted to
-$150,000.00.
-
-Charles Krum's son Howard, after graduation, joined with his father in
-the developmental work of this new company and, due to his studies in
-electrical engineering, was able to help his father considerably. His
-first love and intended career was music, but he put this aside in favor
-of his father's telegraph printer. However, a tune on the piano which he
-always kept in the laboratory would help him solve many a difficult
-problem.
-
-In 1908 the Krums developed and produced a working model of the
-four-unit-code, plus-minus, high-low-voltage system, which was applied
-to operate the mechanism of an Oliver typewriter. The system was then
-given an operative test on the wires of the Chicago and Alton Railroad,
-of which Joy Morton was a director.
-
-As their research work progressed, Howard studied the various systems in
-current use and, with his father, decided to abandon the plus-minus,
-high-low-voltage system. They turned instead to a system using the
-five-unit permutation code as employed by Baudot in his multiplex
-telegraph in which synchronized terminal apparatus with periodic
-correction was the controlling feature.
-
-Their first joint patent describes a plan for accomplishing synchronized
-reception with transmission using a system of five relays interconnected
-to operate in successive cascade form; thus, when the relays at both
-terminals are correctly timed for successive operation, they will
-transmit and receive the five pulse combinations of the Baudot code. For
-transmitting and receiving the code pulses, each of the five relays has
-an additional contact. To start the relay cascade operation, a start
-relay is added at both terminals and operated by a start pulse which
-precedes each code transmission. It seemed natural for the Krums to turn
-to a relay system at first, since, from his work with the
-three-unit-code, high-low-voltage system, C. L. Krum was experienced
-with the possibilities of relay operation.
-
-The system of the relay chain in cascade operation was employed to
-operate a page printer using the mechanisms of the Blickensdoerfer
-typewriter which had a three-row typewheel. The Postal Telegraph Company
-became interested and bought a number of these printers in 1910. This
-was the first sale of Morkrum apparatus and provided enthusiasm for the
-Krums for further research, which led to the substitution of a
-governed-motor-driven brush distributor to replace the relay cascade
-system. For this new plan the motor at the receiving printer operated at
-a slightly higher speed and was held in continuously synchronous
-operation with the transmitter by the periodic transmission of a
-correcting pulse. The new code selecting and printer control system was
-also adapted to operate the mechanism of the Blickensdoerfer typewheel
-typewriter. The idea worked out better than the cascade relay system,
-and a number of printers using this method were constructed and named
-the "Morkrum Blue Code." A few were put in service at the Postal
-Telegraph Company.
-
-The Associated Press (AP) became interested in the Morkrum "Blue Code"
-printer system as a replacement for the low-speed Morse system which was
-being used to transmit news items to newspapers in many cities. Here,
-continuous transmission under control of a code-punched tape, as used in
-the Morse code system, was a requirement, so Messrs. Krum set to work
-and designed a keyboard-operated, five-unit, Baudot-code perforator and
-an automatic punched-tape-controlled transmitter. This apparatus was
-installed at the New York headquarters in 1915 and receiving printers
-were gradually installed throughout the Associated Press system. The
-following excerpt and picture (fig. 6) from Oliver Gramling's book,
-_AP--The Story of News_,[4] describes the introduction of the system to
-the Associated Press:
-
- The tide of news by telegraph had continued with the years. Facilities
- had been improved, the Morse clicked into virtually every town in the
- country, but the old method was the same. Day in and day out, sending
- operators took dispatches, translated them into the dash-dot of code,
- and the telegraph keys sent the signals on the circuits at a rate of
- twenty-five to thirty-five words a minute. In member newspaper offices
- along the line the Morse sounders clack-clacked busily and receiving
- operators translated the code symbols back into words, copying the
- stories in jerky spurts. The news of more than half a century had been
- handled that way.
-
- For some time, however, Charles L. Krum, a Chicago cold-storage
- engineer, and his son Howard had been working to perfect an automatic
- machine which would send the printed word by wire at greater speed
- without the intermediary of code. They called their invention the
- Morkrum Telegraph Printer--coining the word Morkrum by combining the
- inventor's name with the first syllable in the last name of Joy
- Morton, a Chicago businessman who financed them.
-
- [Illustration: Fig. 6
- A SENDING OPERATOR SAT AT A KEYBOARD LIKE THAT OF A TYPEWRITER.
- Reproduced from _AP--The Story of News_, by permission of Associated
- Press.]
-
- Several other automatic telegraphic devices were being promoted, but
- (Kent) Cooper and engineers in the Traffic Department decided Krum's
- machine held the most promise for their purposes. Tests got under way.
- In the Associated Press headquarters, which had been moved seven
- blocks from the old Western Union building to 51 Chambers Street, a
- sending operator sat at a keyboard similar to that of an ordinary
- typewriter. As he struck the keys, copying the dispatches before him,
- the machine perforated a paper tape with a series of holes, each
- combination representing a letter. The tape fed into a box-like
- transmitter which transformed the tape perforations into electrical
- impulses and sent them along the wires into the receiving machines in
- newspaper offices. These impulses actuated telegraph relays and set
- the receiving Morkrum machines automatically reproducing the letters
- which the sending operators were typing miles away.
-
- The tests demonstrated that the Morkrum could transmit news hour after
- hour at the rate of sixty words a minute and the copy was delivered
- clean and uniform. Thus began the slow extension of Morkrum
- transmission to the whole leased wire system, replacing the "brass
- pounding" Morse keys. It was a transition that required years and
- until it was completed both Morse and Morkrum worked side by side in
- many places.
-
-An interesting story appeared recently in "The AP World,"[5] giving some
-recollections of AP's first field maintenance man, Royal (Roy) Bailey,
-then aged 71 and living in retirement in California. He still remembers
-the AP's first printing telegraph machines, the article says; in fact,
-he helped make them, for he was a mechanic in the Morkrum Company's
-factory in Chicago. When the Morkrum Company shipped the first machines
-to AP headquarters, Bailey went along with the machines to install and
-maintain them, although he remained on the Morkrum Company's payroll. He
-eventually installed AP printers all over New York City and Connecticut,
-in Newark, Philadelphia, Baltimore and Washington, and in Chicago, St.
-Louis and Kansas City. He recalls that Morse telegraphers "used to groan
-when they first saw him." The early teleprinters were hard to keep
-synchronized, Bailey further recalls, and copy boys had to check the
-speed frequently by sighting the striped motor flywheel through a tuning
-fork. (Many of those copy boys, he says, including Mickey Burt and Henry
-Elling, became AP engineers.)
-
-As the experimental and developmental work continued at the Morkrum
-plant, Howard Krum studied all types of start-stop systems and found
-that synchronous control was the basis of all systems. After
-experimenting with various ideas his thoughts turned to a plan to make
-the start of the receiving unit somewhat independent of the transmitting
-unit start, thus avoiding irregularities then present in transmitter
-start devices. This idea led to the construction of a permutation-code,
-start-stop system, using segmented commutators with rotating brush
-distributors at both transmitting and receiving units and a start magnet
-for each to control start-stop operation.
-
-In this system the transmitter start magnet, when energized, releases
-the transmitting brush, which immediately contacts the first segment to
-transmit a start pulse to operate the receiver start magnet; the
-five-unit-code signal combination follows and both transmitting and
-receiving units are stopped. The apparatus was applied to control the
-selecting and printing mechanism of the Blickensdoerfer typewheel
-typewriter and named the "Morkrum Green Code." This improved apparatus
-soon replaced the Blue Code printer at Associated Press and other
-installations (see figs. 7 and 7A).
-
-In this connection the following additional comments of Mr. Bailey may
-be of interest:[6]
-
- In 1919 I installed the New York-Washington circuit, with drops at
- Philadelphia and Baltimore. This was a new type of printer using what
- we called the Green Code. This was considered an improvement over the
- old Blue Code, which meant a rearrangement of the receiving mechanism,
- but still the machines made use of a typewheel....
-
- Our biggest job of all came in 1923 when we changed over all the old
- Blue Code typewheel printers in the New York area to the new style L.
- C. Smith typebar printers using Green Code. (Morkrum bought L. C.
- Smith typewriters and added new machinery to them. Those printers
- became the famous Model 12.)
-
-As we have seen, a number of inventors had patented ways and means to
-adopt the five-unit code for operating a telegraph printer system by the
-transmission of a start pulse to start both transmitting apparatus and
-the distant receiving apparatus at the same time, followed by
-transmission of a selected code and a stop pulse. To achieve successful
-operation, very close speed adjustment was required. At first, this was
-achieved by the use of governed motors and, later, when accurately
-timed, 60-cycle alternating current became available, the problem of
-synchronous operation of send and receive stations was solved by the use
-of synchronous motors.

-
-Telegraph printer systems of this type were used by telegraph companies
-for city-to-city transmission of telegrams and by news-gathering and
--distributing organizations to transmit the news from headquarters to
-newspapers in different cities. While start-stop systems of this type
-were used successfully on press circuits and on telegraph message
-station-to-station circuitry, trouble was experienced when a number of
-printer send-receive units were set up in an intercommunicating system.
-Here it was found that the receiver start was not always in time with
-the transmitter start, due to varying line circuit conditions and a
-variation in the start release mechanism at connected stations.
-
-It seems odd that synchronous systems, where both transmitter and
-receiver were started at the same time (requiring both transmitter and
-receiver to maintain synchronism), held the field for so long a time,
-thus limiting telegraph transmission to one-way operation.
-
-It evidently took a mind not bound or hampered by the standard and
-accepted way of operating synchronous systems to discard such old ideas
-and to set forth boldly on a new pattern which, in reality, differed but
-slightly from the then-established synchronous systems, and to sow the
-seed for starting further developments leading to the present telegraph
-typewriter, TWX, and TELEX intercommunicating systems. Such a man was
-Howard L. Krum, who, in further thinking on the subject, came upon the
-almost simple idea of having the transmitter start the receiver rather
-than having them both start at the same time. This arrangement required
-higher speed operation of the receiver and therefore the receiving code
-pulse positions were spread over a shorter area, which meant
-progressively decreasing the angular division of the receiving members.
-Then, to set the received start pulse in the most favorable position
-with relation to the following code signal reception, an orientation
-adjustment of the receiver start position was provided.
-
-(Note: On June 20, 1961, Kleinschmidt wrote to Howard Krum--then in
-retirement in California--giving a short description of the Morkrum
-Company activities, including the wording of the above last two
-paragraphs, and asking him to write the Morkrum story. Howard Krum
-replied on July 3, 1961, indicating his approval and saying that he
-would be glad to put together some notes for Kleinschmidt. It was quite
-a shock, therefore, when a letter was received from Howard Krum's son,
-Charles, in September of 1961, telling of his father's sudden serious
-illness. Then, regretfully, it was not long afterwards that word was
-received of Howard Krum's death on November 13, 1961.)
-
- [Illustration: Fig. 8
- Morkrum Company No. 12 Typebar Page Printer
- _Picture through courtesy of Teletype Corporation_]
-
-Howard Krum's improved method for operating start-stop, permutation-code
-telegraph systems was first applied to the Morkrum Green Code apparatus
-to control the selecting and printing operations of the Blickensdoerfer
-typewheel typewriter.
-
-At this time the Kleinschmidt company and other manufacturers were
-starting to produce permutation-code, start-stop telegraph printers
-using typebar printing like the more modern typewriters which began
-rapidly to replace the Blickensdoerfer, the Hammond, and the other
-typewheel printing typewriters. Observing this situation, the Morkrum
-Company started intensive development work to produce the No. 12 typebar
-page printer, using the typebars and operating mechanism of the L. C.
-Smith typewriter and platen of a Woodstock typewriter (fig. 8).
-
-Further developments produced the Morkrum No. 11 tape printer which used
-the Baudot combiner method for selecting and printing characters under
-control of start-stop, send-receive devices. The No. 11 was a small,
-compact tape printer operating at fifty words per minute. Quite a number
-were put into service at hotels and elsewhere for local message service
-(fig. 9).
-
- [Illustration: Fig. 9
- Morkrum Company No. 11 Tape Printer
- _Picture through courtesy of Teletype Corporation_]
-
-The new No. 12 typebar page printer found numerous applications. It
-replaced the Green Code and the earlier Blue Code wherever used. The new
-No. 12 was installed at Western Union, on some railroads, and in the
-Chicago Police telegraph system. The No. 12s were also installed by
-Postal Telegraph on intercity circuits and used as receiving units for
-the Postal Multiplex. The Postal Multiplex had been designed by Morkrum
-and Postal engineers with the consultant assistance of Donald Murray who
-was a friendly associate and had a license agreement with the Morkrum
-Company covering some of his patents. A few No. 12 Morkrums were shipped
-abroad for use with the Murray Multiplex; the British Post Office
-Telegraph and the Australian Telegraph Administration were customers.
-
-Late in 1924 the Morkrum Company and the Kleinschmidt Electric Company
-joined to form the Morkrum-Kleinschmidt Corporation. A story telling of
-the union of these two companies was published by _Fortune_ magazine in
-March of 1932.[7]
-
-Before going to that story, it may be of interest to describe an
-important event concerning the change in the supply of electric power
-from direct current to 60-cycle alternating current and the final timing
-to exactly 60 cycles per second of all A.C. power supplies so that our
-electric clocks may be connected to an A.C. outlet and give correct
-time.
-
-The advent of correctly timed, 60-cycle A.C. electric power, available
-throughout the nation, was a great boon to the designers of printing
-telegraph apparatus and some types of facsimile telegraph and picture
-transmitting systems. In prior years, overline synchronization of send
-and receive apparatus was always a problem and never perfect. Today,
-synchronizing apparatus between terminals becomes the simple matter of
-providing 60-cycle A.C. synchronous motors. Just plug into a power
-outlet and you have "sync"!
-
-Henry Ellis Warren, a clock maker, noting the change in electric power
-service from direct current to 60-cycle alternating current, set about
-to build a motor to operate at 60-cycle speed but found that the
-60-cycle frequency did not always hold to form, and when applied to
-running a clock, did not hold correct time.
-
-The following excerpt, from _The Romance of Time_,[8] tells of Warren's
-activities which led to synchronizing 60-cycle alternating current to
-exact time:
-
- _Synchronous Electric Time_
-
- One of the most important of all contributions to horology is the work
- of an American who has earned the title, "Father of Electric Time."
-
- Henry Ellis Warren was graduated from Massachusetts Institute of
- Technology in 1894. In 1907 he married and settled in Ashland,
- Massachusetts. Here it was that he began to work out his idea for
- electrically operated timepieces.
-
- His first product was an ingenious battery-operated clock. In 1914 he
- organized the Warren Clock Company and set up production in a barn on
- his farm. Yet he knew the battery clock was not his goal, for direct
- current offered no means of accurate regulation. Direct current flows
- constantly in one direction only, like water down a river or like the
- passage of time. On the other hand, alternating current changes
- direction regularly, like the oscillation of the balance wheel in a
- watch. But instead of the usual five times a second of the balance
- wheel, most alternating current completes its trip forward and
- backward sixty times a second. Obviously, a clock "geared" to such a
- frequency would run as reliably as the current.
-
- In 1916, after several years of extensive experimentation, Warren
- developed a motor which would start by itself, run on alternating
- current, and carry without difficulty the load of reduction gears
- driving the clock hands. It could also handle the cams and contacts of
- an alarm clock or set in motion a striking or chiming mechanism.
-
- Then came the test. He plugged the clock into the power socket. It
- commenced to run. Weeks of observation and checking showed an
- irregular error of as much as ten to fifteen minutes a day.
-
- Convinced that his clock was right, Warren discovered that the
- alternating current frequency delivered to his barn factory was off
- half a cycle per second--59-1/2 and not 60 cycles. This slight
- deflection would produce that much time loss in a 24-hour run. When he
- informed the electric company of this error, he was met at first with
- polite disbelief. Yet he showed such a comprehensive knowledge of the
- subject that the company began to recheck their standards.
-
- Warren built several more synchronous clocks and a master regulator of
- his own design for power-station use. On one dial of his master clock
- there were two hands, black and gold. The black hand was connected to
- an accurately adjusted pendulum clock, beating seconds. The gold hand
- was driven by the gear train of one of his electric clocks. As long as
- the two hands revolved together, the current cycles were exactly 60
- per second. Set up in a power station, this allowed the operator to
- adjust the turbine generators as needed to keep the two hands of the
- master clock together. Thus all other properly set electric clocks on
- the same system would keep the same time automatically.
-
- The Edison Electric Illuminating Company of Boston tried out the
- master clock on October 23, 1916. Since then this regulation has
- continued.
-
- Other power companies adopted Warren's master clock. Today virtually
- all alternating current furnished in America is similarly checked.
- Practical electric time is available at the light socket almost
- everywhere. But there are additional benefits.
-
- Standardizing the frequency expanded the market for current to run the
- increasing number of clocks in use. Yet, from the consumer's point of
- view, each clock draws little current, costing but a few pennies a
- month. Uniform frequency also gave more even speeds in motor-driven
- machinery, with a resultant improvement in product. It made easier the
- joining of one power station to another. Synchronous motors used in
- certain meters and recorders produced better, more accurate records at
- lower cost.
-
- The Warren enterprise expanded rapidly. The battery clock was
- discontinued. The red barn was no longer large enough, and new space
- was acquired. The trade mark "Telechron," meaning "time from a
- distance" (from two Greek words), was used to identify all products of
- the company. The firm name was changed to stress the name Telechron,
- and in 1952 a merger was made with the General Electric Company.
- Plants are now operated in Worcester as well as in Ashland,
- Massachusetts.
-
-And now back to the telegraph field....

- CHAPTER 4
- Morkrum-Kleinschmidt Corporation
- (later renamed "Teletype Corporation")
-
-
-During and after the first world war, both the Morkrum Company and the
-Kleinschmidt Electric Company were progressively developing and
-producing telegraph apparatus and bringing out new and improved
-operating devices to a point where conflicting patents were at issue.
-This meant infringement litigation which might destroy both companies.
-Neither company could obtain orders in sufficient quantity to make the
-manufacturing of apparatus profitable, and, with costly development work
-at hand, more capital investment was a continuous requirement.
-
-The following excerpts from the March 1932 issue of _Fortune_[9] tells
-of the final joining of the two companies.
-
- The Morkrum Co. had no profits to show for its efforts, and one can be
- fairly safe in assuming that no other maker of telegraph printers made
- profits. There were competitors, of course. Even the first telegraph
- invented by Samuel Morse had a printer, but it printed in dots and
- dashes instead of in letters of the English alphabet. That original
- Morse printer was abandoned as far back as 1844 because a man who
- could be trained to read dots and dashes could just as easily be
- trained to listen to them. The problem of getting a printer to print
- the alphabet was faced by inventors more than half a century ago, and
- it was not really a difficult problem. The difficulty was to invent a
- printer that was not too complicated and delicate to be reliable, that
- was simple enough to be manufactured for a few hundred instead of a
- few thousand dollars.
-
- This difficulty occupied many minds other than the Morton-Krum
- intelligences. The most noteworthy of Morkrum Co.'s rivals in
- printer-making was Edward Kleinschmidt, an inventor who had all the
- inventor's legendary devotion to his task and to nothing else. His
- creations included a vaccination shield, an automatic fishing reel,
- and the perfection of the Wheatstone perforator. He had been tinkering
- with a telegraph printer in one form and another since the beginning
- of the century. In 1917 his project was revamped. It had the financial
- backing of Charles B. Goodspeed, of the Buckeye Steel Casting Co.;
- Paul M. Benedict, assistant to the president of the C. B. & Q.; Edward
- Moore, son of Judge Moore of American Can fame; Eldon Bisbee, a New
- York lawyer; and one of Mr. Bisbee's legal clients, Albert Henry
- Wiggin, then president of the Chase National Bank. It was Mr.
- Goodspeed, a quiet, retiring gentleman, who supplied most of the
- corporate (as distinct from inventive) energy of the Kleinschmidt
- Electric Co....
-
- In the years from 1917 to 1924 the Kleinschmidt and the Morkrum
- companies became the leading makers of telegraph printers, but they
- did not have an easy row to hoe. Their only possible customers were
- the two great telegraph companies, the Telephone company, the
- railroads, and an occasional outside business such as a press
- association. The competition was disheartening, and it became keener
- with the elevation of Sterling, son of Joy Morton, to the presidency
- of the Morkrum Co., an elevation that was mainly a War-time accident,
- for Sterling Morton had resigned from his father's company to enlist
- in the Army, had been rejected because of a small steel plate in his
- anatomy, and had chosen the Morkrum Co. as an alternative. Engineering
- progress was made, sometimes under ludicrous circumstances.
-
- There was one occasion when Sterling Morton, about to sail for Europe,
- heard that the Kleinschmidt Co. was about to bring out a simplex
- printer. Up to that time both companies had been making printers for
- use with multiplex machines. Mr. Morton was afraid that Mr.
- Kleinschmidt was about to anticipate him in the simplex development
- which was the forerunner of the present teletypewriter. This was a
- contingency which Mr. Morton could not well permit. On the spur of the
- moment, he called on Howard Krum, who happened to be in New York. They
- bought a drawing board, hired a room at the Princeton Club, and worked
- for twenty-four hours trying to design such a machine. Completely
- baffled by one small detail, they gave up and took a bus for Coney
- Island. On the way, Howard Krum doubled up in sudden ecstacy and
- inspiration. They rushed from the bus at Coney Island, entered a soda
- fountain, and on the spot designed the machine on the back of an
- envelope. This simplex machine of the Morkrum Co. and the one
- developed by Kleinschmidt at the same time are the machines which make
- Teletype commercially important, the substance of the business today.
-
- But engineering progress was not business progress. Both companies
- from the standpoint of profits were failures. Their few customers
- played them off against each other. In despair, they were both willing
- to sell out. At one point Mr. Goodspeed offered the Kleinschmidt
- company to Mr. Newcomb Carlton of Western Union for $412,000, the
- amount invested in it. Mr. Morton sold his company in all but fact to
- Mr. Charles G. du Bois, then president of Western Electric, but Mr. du
- Bois went off to Europe, and his substitute refused to see any merit
- in the deal. So it fell through. Unable to sell themselves to their
- customers, they tried selling themselves to each other. In 1923
- Messrs. Goodspeed and Morton came to terms. The Morkrum Co. signed the
- agreement and, everything arranged, Mr. Goodspeed went off to bicycle
- with his wife in South Africa--whereupon his company suddenly changed
- its mind.
-
- That was the situation of these two unfortunate companies in 1924 when
- Mr. Morton started a suit for patent infringement against his rivals.
- A counter suit was promptly filed. Mr. Goodspeed was quite right when
- he said the suits would ruin both--there was every prospect that by
- the time the courts had settled things, the patents would have been in
- such a snarl that neither could do anything. The suit, in fact, was
- Sterling Morton's way of bringing matters to a head. So, figuratively
- speaking, on the courthouse steps they merged.
-
- The terms of the merger as embodied in the six-line agreement (it was
- later made over into a twenty-five-page legal document which concluded
- by saying that in case of dispute the six-line agreement should be the
- final authority) were these: each of the old companies received a half
- interest in the common stock (10,000 shares) of the new company;
- 15,000 shares (callable at 105) of the new company's preferred stock
- should be divided according to the assets of the old companies.
- Actually, 13,979 shares of preferred were issued, the majority going
- to the Morkrum group.
-
-And so it was that the agreement to join both companies under the name
-Morkrum-Kleinschmidt Corporation was consummated and chartered in the
-State of Delaware on December 29, 1924, with Sterling Morton as
-President, Howard L. Krum as Vice President in charge of manufacturing,
-and Edward E. Kleinschmidt as Vice President in charge of development,
-patents and foreign sales.
-
-One of the first decisions to make was whether the Kleinschmidt plant in
-Long Island City or the Morkrum plant in Chicago would be the
-headquarters for the new company. The Kleinschmidt company was on a
-27,000-foot leased floor in a building which R. H. Macy Company had just
-purchased to use for a warehouse, and negotiations had been going on for
-some time for the purchase of the Kleinschmidt lease--the sum of
-$25,000.00 having been offered. When the union of the two companies was
-decided upon, an agreement to vacate on the terms offered was signed,
-and the Kleinschmidt firm moved to the Morkrum-owned plant in Chicago.
-
- [Illustration: Fig. 10
- Morkrum-Kleinschmidt Corporation No. 14 Start-Stop Typebar Tape Printer
- _Picture through courtesy of Teletype Corporation_]
-
-Bringing together the engineering talent and patents of the two
-companies had an immediate effect toward further progress. The first
-thing the new company set out to do, through consolidation of their past
-efforts, was to perfect a satisfactory start-stop-operated tape printer
-for the Western Union Telegraph Company to use for circuit extension to
-customers who were extensively using the telegraph for immediate,
-written communication. (This was to speed up telegraphic communication
-and eliminate the need for messenger service which had been the custom.)
-The Morkrum company had submitted their start-stop-operated Baudot tape
-printer, and the Kleinschmidt company had proposed the Western Union No.
-22 tape printer in a redesign to start-stop operation. Now, the new
-company was able to combine both plans and as a result came up with
-their first development, a typebar, start-stop-operated, tape printer,
-the No. 14 (see figure 10). In the final design, Howard Krum and his
-production engineers took a large part. After tests and evaluation,
-Western Union's first order was for 10,000 machines at $317.00 each.
-This amounted to a total of $3,170,000.00. No such quantity had ever
-been heard of before!
-
-It is quite evident that while the two companies were separated, each
-coming up with improved and new designs of telegraph apparatus, there
-was a lack of decision by telegraph companies as to which type of
-apparatus to adopt in expanding their operations, and therefore they did
-not buy in quantity. The largest previous order to the Kleinschmidt
-Electric Company was for 800 No. 22 typebar tape printers for the
-Western Union Multiplex.
-
-At Morkrum-Kleinschmidt more space was needed. The corner property on
-Wrightwood Avenue adjoining the Morkrum plant was purchased, and a
-four-story building was erected.
-
-The design of a telegraph typewriter that would be more efficient and
-require a minimum of maintenance service was the most important project,
-and Morkrum-Kleinschmidt was working with Bell Laboratories engineers
-endeavoring to meet all the requirements of the Bell Telephone system. A
-typebar printer with a stationary printing platen and moving typebar
-printing unit was specified. These requirements were finally met with
-the design of the No. 15 page printer to operate at 60 words per minute,
-and manufacture of this apparatus was started in 1927 (see figure 11).
-The No. 15 page printer became the standard for nationwide
-intercommunicating telegraph service for many years.
-
-In 1926, soon after the No. 14 tape printer was put into service,
-Morkrum-Kleinschmidt received a request from the police department of
-Berlin, Germany, for detailed information, stating that they were
-interested in the purchase of about sixty No. 14 printers. The letter
-asked if Morkrum-Kleinschmidt was represented by an agent in Germany
-whom they could contact. At an executive meeting, Mr. Morton and Mr.
-Krum asked Mr. Kleinschmidt to take care of this matter since his
-company, before joining them, had sold apparatus in some foreign
-countries. After further correspondence with the Berlin police
-officials, Kleinschmidt decided personally to take a No. 14 printer to
-Germany and arrange for a representative there. After visiting and
-conferring with several companies experienced in the telegraph and
-associated apparatus field, a satisfactory arrangement was consummated
-with the C. Lorenz Company, on October 25, 1926, for the manufacture and
-sale of Morkrum-Kleinschmidt equipment in Germany, on a
-royalty-licensing basis. At that time the Lorenz company manufactured
-telegraph and telephone equipment and railway signaling apparatus. Their
-engineering department was under the supervision of Dr. Gerhard Grimsen
-who took the matter in hand for further exploitation toward an
-intercommunicating printing telegraph system, using the No. 15 page
-teletypewriter. Siemens & Halske, the principal manufacturers of
-telegraph equipment in Germany, were also licensed by the
-Morkrum-Kleinschmidt Corporation, on June 1, 1929, with the consent of
-the Lorenz company.
-
- [Illustration: Fig. 11

- _Picture through courtesy of Teletype Corporation_]
-
-(As may be seen in the following chapter, it was these licensing
-arrangements which led to the establishment of the TELEX
-intercommunicating teleprinter system in Europe.)
-
-In early 1927 the well-known newspaper publisher, Mr. Frank E. Gannett,
-came to Morkrum-Kleinschmidt, bringing his company's engineer, Mr.
-Walter Morey, who had heard of various attempts to operate a typesetting
-machine, such as Linotype or Intertype, directly from the telegraph. Mr.
-Gannett said, "We have telegraph typewriters in our news rooms that
-record the news as transmitted from the Associated Press and the United
-Press, and that is fine. Now, why not go a step further and operate our
-typesetting machines directly from the telegraph circuit? If you can
-develop such a device, I will help finance the project."
-
-Indeed, after some study of the matter, the possibility of devising such
-a system seemed entirely feasible and the development of suitable
-apparatus was turned over to the research and development department. A
-workable plan was soon put together and a separate company, the
-Teletypesetter Company, was organized, with Mr. Gannett joining
-financially. Edward Kleinschmidt was elected president. Development
-proceeded and a complete set of apparatus was set up and publicly
-demonstrated for the first time on December 6, 1928, at one of Mr.
-Gannett's newspapers, _The Times Union_ of Rochester, New York.
-Teletypesetter equipment was subsequently manufactured for several
-installations. After the Western Electric Company purchased the Teletype
-Corporation in 1930, the Teletypesetter Company was sold to the
-Fairchild Company. Teletypesetter equipment is now in universal use by
-most newspapers and the larger printing companies.
-
-During the period that the United States' business cycle was on a
-continuous upswing (during the late 1920s), securities sales on the New
-York Stock Exchange were going to constantly higher volume, and the old
-step-by-step stock ticker did not, by large margins, keep pace in
-recording stock share transactions. There was a cry for a higher speed
-stock ticker; in fact, the Stock Exchange officials told
-Morkrum-Kleinschmidt that they would be happy to convert the entire
-system if they could get higher speed.
-
-An adaptation of the five-unit-code, start-stop system seemed the
-solution and the Research and Development department set out to develop
-suitable apparatus. Several ideas were studied and, because of the
-frequent changes from letters to figures, requiring printing in separate
-rows on the tape, a six-unit code was adapted instead in which
-combinations for a figure included the sixth selecting pulse to operate
-the figures print hammer and block the letters print hammer.
-

- Morkrum-Kleinschmidt Corporation Stock Ticker
- _Picture through courtesy of Teletype Corporation_]
-
-The Morkrum-Kleinschmidt company was soon able to show the Stock
-Exchange people a stock ticker operating on a telegraph system that
-worked at twice the speed of the step-by-step-operated tickers then in
-use. A speed of 500 printing operations per minute could be obtained,
-thus attaining a one-hundred-percent increase in the transmitting and
-recording of stock quotations on the tape (see figure 12). The Stock
-Exchange ticker service company ordered 15,000 of these high-speed
-tickers and the Western Union Telegraph Company also ordered a quantity
-for their national stock quotations distributing systems.
-
-As business of the combined Morkrum and Kleinschmidt companies went
-along, it was thought that the name "Morkrum-Kleinschmidt Corporation"
-was a pretty big mouthful and that a simpler name more characteristic of
-its products would be better. The name "Teletype" was suggested, and in
-the year 1928 the name change to "Teletype Corporation" was made. The
-exact origin of the word "teletype" is not known but it is no doubt one
-of the abbreviated forms of the words "telegraph typewriter" which were
-used over the years. In literature, in the early 1900s, we find that the
-word "teletype," in speaking of printing telegraph equipment, and other
-shortened forms, such as "telewriter" and "teletyper," were used
-interchangeably.
-
-Kleinschmidt's son, Edward F., who studied electrical engineering at
-Steven's Institute and at Northwestern University, was employed as
-development engineer by the Morkrum-Kleinschmidt company where he
-assisted in the design of projects at hand, and, during 1929, produced a
-system and apparatus for transmitting and recording printed characters
-by the successive transmission of dots arranged in a pattern to form
-letters. While this system required a higher signaling frequency, it was
-thought to be superior to permutation-code transmission over radio
-circuits where electrostatic interference is experienced, since, in the
-dot pattern transmission, electrostatic interference up to a degree will
-not change the readability of a transmitted letter.
-
-The system was in test operation to prove its efficiency over radio
-circuits where considerable static interference was experienced. Upon
-hearing of this new telegraph for the radio, Mr. R. Stanley Dollar
-became interested in the use of this communicating system for his
-steamship line. There was considerable correspondence in this matter
-during mid-1930, just prior to the sale of Teletype; however, neither
-AT&T nor Western Electric was interested in further promoting this new
-radio telegraph, so the matter was dropped.
-
-Business activities of Teletype Corporation were now growing rapidly and
-with good profit. The capital structure of 10,000 shares was wholly
-inadequate, so by a 15-to-1 stock dividend the capital structure was
-raised to 150,000 shares, and dividends on an annual basis of $12.00
-were paid.
-
-The successful development of apparatus for different applications
-useful in the telegraph field was largely due to the close cooperation
-between the research-development and the manufacturing departments of
-the organization. Howard Krum had expert engineers and designers in his
-department, Kleinschmidt brought his leading engineers and designers
-from the Long Island City plant, and there was a definite spirit of
-cooperation all around.
-
-To quote again from the _Fortune_ magazine story:[10]
-
- As the years up to 1925, when the Kleinschmidt-Morkrum merger took
- place, were wanderings in a profitless desert, so the years from 1925
- to 1930 found the teletype in a land of milk and honey. Mr. Morton,
- however, was inclined to think that a company which had only two or
- three major customers is not strongly placed. Furthermore (and by the
- spring of 1930), at least one of those customers was actively in the
- market as a Teletype purchaser. This buyer was Colonel Sosthenes Behn,
- whose International Telephone & Telegraph Co. includes Postal
- Telegraph at home in addition to many communication and manufacturing
- companies abroad. With Colonel Behn wanting to buy and Mr. Morton
- wanting to sell, negotiations rapidly proceeded to a point at which
- Mr. Morton, at least, thought the deal was almost concluded. But while
- Mr. Morton and the Colonel were discussing the prospective
- acquisition, into the Colonel's office walked a man who has no other
- place in this story except that he happened to interrupt at this
- moment. As this gentleman was introduced, he asked whether Mr. Morton
- were related to Joy or Paul Morton. When Mr. Morton admitted that they
- were his father and uncle, the man turned to Colonel Behn and said in
- jest: "Better watch your step. That's a smart family." Only Colonel
- Behn knows whether he gave that remark any weight, but the point is
- that the negotiations suddenly collapsed, and that the visitor's
- remark about the smart family still lives vividly in Mr. Morton's
- memory.
-
- This setback was not a setback at all to such a negotiator as Mr.
- Morton. Two months later, in May, 1930, you find him walking into the
- office of Clarence G. Stoll, vice president of Western Electric, A. T.
- & T.'s manufacturing subsidiary. This time there had been no
- preliminaries. Mr. Stoll rose from his desk and said: "Good morning.
- What can I do for you?"
-
- "Do you want to buy Teletype?"
-
- "Is it for sale?"
-
- "Yes, at a price."
-
- "All right. Let's get down to business."
-
- They got down to business on the spot, and they remained at it for
- three solid days in Mr. Stoll's office. The agreement as reached
- called for A. T. & T. to pay off the preferred stock of Teletype,
- 13,979 shares callable at 105, and to give one share of A. T. & T. in
- exchange for each common share of Teletype. The A. T. & T. shares were
- worth about $200, so the price came to upwards of $30,000,000--plus,
- of course, the $1,467,795 for retiring the Teletype preferred.
-
-It should be noted here that this deal to take over Teletype on a
-share-for-share basis was exclusive of foreign patent rights but did
-include patent rights in Canada and Mexico.
-
-The sale to Western Electric was closed on September 30, 1930. Mr. Stoll
-of that company was made president. Howard Krum continued on as vice
-president and was a leader in developing a number of commendable
-devices, including a system for transmitting messages in scrambled,
-untranslatable code form and receiving such scrambled code in perfect
-message form. Mr. Morton was retained as consultant. Edward Kleinschmidt
-made an arrangement to do development work for the new organization in a
-laboratory of his own, assigning all inventions to the Teletype
-Corporation (see page 50).
-
-After Kleinschmidt left Teletype, his assistant, Albert H. Reiber,
-carried on as head of Research and Development for a short while before
-his untimely death. In the meantime, Walter J. Zenner had advanced and,
-in 1935, became Department Chief and later Vice President in Charge of
-Research and Development. Under Zenner's direction a number of new
-devices in the teleprinter field were developed, including
-ultra-high-speed tape-perforating and tape-controlled transmitting
-devices, as well as a high-speed stock ticker operating at 900
-characters per minute (introduced in 1964) to replace the earlier
-Morkrum-Kleinschmidt ticker which operated at 500 characters per minute.
-Some 94 patents were issued in his name, which have contributed greatly
-to the growth of the Teletype Corporation.[11]
-
-On May 15, 1940, Howard Krum and Edward E. Kleinschmidt were both
-honored by The Franklin Institute and awarded the John Price Wetherill
-Medal, each one "For his Part in the Development of a Successful
-Electrically Operated Duplicate Typewriting Machine Now Known as the
-Teletypewriter," (Quoted from the medal certificate.)
-

-
-Howard Krum later also received an award as Modern Pioneer from the
-National Manufacturers Association. Edward E. Kleinschmidt, on April 19,
-1958, was awarded the honorary degree of Doctor of Engineering at the
-Polytechnic Institute of Brooklyn.
-
-To continue: After the sale of patent rights in Canada, Mexico, and the
-United States to Western Electric, there remained the European and other
-foreign patent rights still with the original Morkrum and Kleinschmidt
-investors. The International Telephone and Telegraph Company wanted
-these rights, and, after negotiations in New York, a price was set for
-their purchase through the Creed Company in London, then owned by IT&T.
-Edward Kleinschmidt was sent to London in 1930 to close the deal. Some
-changes to the sales contract were requested by Creed which kept the
-cables busy by Kleinschmidt in asking for approval from A. T. & T. and
-Western Electric lawyers. Finally, upon all-around approval, the
-contract was signed at the previously-agreed-to price of one and a
-quarter million dollars.

- CHAPTER 5
- Teletypewriter Intercommunication Expands
-
-
- _TELEX_
-
-As a result of the acquisition of patents of the Morkrum-Kleinschmidt
-Company by the Lorenz company, Siemens & Halske, and, later, the Creed
-company in England, all of which we have discussed briefly,
-teletypewriter intercommunicating expanded rapidly. In just a short
-time, through the cooperation of these companies, it spread over all of
-Europe and was named TELEX (_TEL_eprinter _EX_change Service).
-
-Dr. Gerhard Grimsen of the Lorenz company, in a letter to Edward E.
-Kleinschmidt, dated July 11, 1962, states, in part (slightly edited):
-
- The story of printing telegraph apparatus using an equal length code
- in the Lorenz Co. commences in 1927 with the acquisition of the most
- important patents of the Morkrum-Kleinschmidt Co.
-
- Before then, the Lorenz people were busy in manufacturing Morse
- apparatus and delivering exchange tickers which used the Hughes code.
- The transmitter had a piano keyboard, the receiver was a page printer
- with a moving type wheel.... The biggest network of this kind was
- installed in the Berlin Police service (with one transmitter and about
- 300 receivers). The connections between the headquarters and the
- substations were built by using guttapercha cable lines owned by the
- police administration. This broadcasting network was erected around
- 1907. By 1927 the cables had aged, by normal corrosion, to such a
- degree that instead of 110-volt double current transmitting voltage,
- little by little, up to 220 volts was necessary for a fairly
- satisfying operation. Also, the maintenance of the apparatus became
- more costly.
-
- This was the situation when some communication experts of the police
- and the post administration made the first studies about the newest
- telegraph technique in the U. S. A.... They found that the start-stop,
- five-unit tape printer, the Model 14, developed and manufactured by
- the Morkrum-Kleinschmidt company, would be the best instrument to
- replace the old ones in the police service as well as in the telegraph
- business of the German post administration.
-
- Of special importance to the police service was the fact that by
- introducing this apparatus, it was not necessary to build a new
- network because now it became possible to rent normal telephone lines
- using single current, 40-milliampere, 60-volt current only.
-
-Siemens and Halske engineers, in 1925, had designed a teleprinter using
-the five-unit-code, start-stop principle. This was manufactured and
-improvements added, including the new start-stop method developed by
-Morkrum-Kleinschmidt. The Creed company, which had started manufacture
-of start-stop teleprinters before 1930, having purchased several Morkrum
-printers before the consolidation of that company with the Kleinschmidt
-company, also designed a teleprinter for the new five-unit-code,
-start-stop system.
-
-In another write-up, Dr. Grimsen states that after the Siemens company
-came into the picture, a fully automatic teleprinter network was started
-in 1933 with a trial installation between Berlin and Hamburg for about
-forty private subscribers. The results were so encouraging that the
-German Reichspost continued the work, and five years later the TELEX
-system contained about 10,000 subscribers.
-
-TELEX service was introduced in Great Britain in 1932 and was worked
-over the telephone network, using a single-tone voice frequency carrier
-signal which was keyed on and off by the teleprinter transmitter. (From
-Freebody's _Telegraphy_.)[12]
-
-Interconnection for TELEX service was made by dialing a subscriber as in
-telephone operation. TELEX directories then, as now, gave the call
-numbers of subscribers. Types of answerback devices were designed in
-both England and Germany which finally developed into an arrangement
-whereby the calling subscriber would, after dialing a number, press a
-special key, the shifted D key--named the "Who-Are-You?" button--which
-would cause the transmission of a signal code automatically to activate
-the called teletypewriter mechanism into transmitting its TELEX number.
-
-Further apparatus, a device to punch the code in a tape and a
-punched-tape-controlled transmitter, was soon added.
-
-The Siemens company also developed and built completely automatic
-switching equipment for the TELEX system which is used by many telegraph
-administrations.
-
-Through the cooperation of the companies who were manufacturing
-teleprinters and associated equipment, the many problems that appeared
-were eventually solved to improve the apparatus and bring the TELEX
-system to eventual perfection for worldwide telegraph communications.
-(At the time of this writing, according to statistics, there are nearly
-1,000,000 TELEX subscribers throughout the world.)
-
-One of the problems faced in setting up such a worldwide system was that
-of standardizing the code and operating speed. At the time of
-Kleinschmidt's stay in London in 1930 to close negotiations with Creed
-for the sale of Morkrum-Kleinschmidt's foreign rights, he met Mr. Martin
-Feuerhahn of the German Telegraph Administration who at that time was in
-conference with Creed and representatives from the British Telegraph
-Administration as to standardizing on an alphabet and telegraph code for
-international communications. Mr. Feuerhahn argued for the adoption of
-the American Murray alphabet and code, stating that he already had the
-approval and consent of the French, Italian, and Belgian telegraph
-administrations.
-
-Mr. Feuerhahn and Kleinschmidt spent some hours together. After their
-return to their respective countries, Kleinschmidt received a letter
-from Mr. Feuerhahn referring to their talks and stating that he had been
-in correspondence with Mr. Benjamin of Western Union and Mr. Parker of
-Bell Laboratories with regard to code and other pertinent matters of
-standardization so that an International Teleprinter Exchange could be
-extended into the United States. Another letter dated October 10, 1931,
-reviewed the aforementioned standardization search.
-
-The Murray alphabet and 7-1/2-unit code were soon adopted and are still
-in use today in TELEX.
-
-In later years, an association, the Consultative Committee on
-International Telegraph (CCIT--now the CCITT to include the telephone),
-was formed and met regularly to discuss problems and to set operating
-regulations for the TELEX apparatus in an intercommunicating system. The
-CCITT at this writing is still meeting regularly on worldwide
-standardization in both telegraph and telephone communications.
-
-
- _TELEX IN THE UNITED STATES AND TWX_
-
-In the United States, in November 1931, the Bell Telephone Companies
-announced an intercommunicating teletypewriter service, called TWX for
-short (_T_eletype_W_riter e_X_change), by which interconnections could
-be made by a switchboard operator as in telephone service. One of their
-first advertisements named it a "Telephone Typewriter Service, a service
-that typewrites by wire, a method of inter-office communication that has
-the quickness of the telephone, the flexibility of conversation, the
-accuracy of the typewriter, the authority of the printed word, the
-permanency of print."[13] Tape-punching and tape-controlled transmitting
-apparatus was provided. This service allowed subscribers to carry on a
-typewritten conversation at a charge less than the cost of a telephone
-call, whether to local or to distant areas. The maximum speed of this
-equipment was limited to sixty words per minute.
-
- [Illustration: Telephone Typewriter Service (early TWX apparatus)
- _reproduced by permission of American telephone & Telegraph Co._]
-
-There are approximately 54,000 subscribers to TWX at this writing, and
-the TWX directory gets fatter with each new issue. In 1962 all TWX
-machines were converted to direct dialing operation, making the service
-easier to use. Instead of going through "Operator" by manually typing
-out the call letters of the party being called, one now merely depresses
-the Originate button, listens for the dial tone, and then dials the TWX
-number of the party wanted.
-
-RCA Communications, Inc., was the first to extend international TELEX
-service to Bell System teletypewriter subscribers (1955), enabling them
-to make and receive overseas calls on their domestic TWX machines.[14]
-As stated, the TWX machines were geared for 60-words-per-minute
-operation, whereas the TELEX system operated at 66 words per minute. It
-was therefore necessary for R.C.A. to use conversion apparatus to an
-error-detecting code for overseas radio transmission. This code was a
-seven-unit code, using three marking and four spacing elements, giving
-35 usable combinations. By using a special printer, when a faulty
-combination was received, a special error symbol was printed.
-
-Western Union, in May of 1958, introduced TELEX service between New York
-City and various Canadian points. By 1962 the service had been extended
-to 67 United States cities, and at this writing they expect to serve 180
-United States cities with an anticipated subscriber capacity of many
-thousands.[15]
-
-In addition to domestic service between U. S. cities, subscribers can
-dial automatic teleprinter connections to Canada and Mexico. Also, they
-can obtain direct TELEX connections to other parts of the world through
-the overseas facilities of RCAC (Radio Corporation of America
-Communications), AC&R (American Cable and Radio), and WUI (Western Union
-International). The operating speed of 66 words per minute and also the
-teleprinter keyboard in the U. S. TELEX network conform to international
-standards of the CCITT. This provides complete operating compatibility
-with other TELEX systems throughout the world without the need for speed
-and keyboard translators.[15]

- CHAPTER 6
- KLEINSCHMIDT LABORATORIES
-
-
-As we have seen, Edward Kleinschmidt, upon resigning from Teletype
-Corporation as vice president when it was taken over by Western
-Electric, had agreed to do development work for them, working
-independently but assigning any inventions to the new Teletype
-Corporation.
-
-And so it was that Kleinschmidt Laboratories came into existence.
-Incorporated on March 21, 1931, under Delaware laws, for the immediate
-purpose of doing research and development work for Teletype, the
-principals of the new company were Edward E. as president, and his two
-sons, Edward F. as vice president and Bernard L. as secretary.
-
-Kleinschmidt had earlier proposed a comprehensive and completely
-automatic printing telegraph switching system in which messages are
-automatically routed from the subscriber printer through telegraph
-centrals of the addressee printer under control of address tape
-perforations. Under his development contract with Teletype he continued
-work on the system. Message storage in perforated tape was provided for
-at all central switching points, and an answerback arrangement was
-included in the system by the automatic return transmission of the
-addressee's number to the sender.
-
-As the research and development work for Teletype continued, the
-switching system was completed, and various other devices of more or
-less importance were developed, with patents assigned to the Teletype
-Corporation. In late 1934 the contract with Teletype expired.
-
-At that time, son Bernard was operating a printing plant in rather close
-quarters in Highland Park, Illinois. The operations of the Laboratories
-had been carried on in rented quarters at the Merchandise Mart in
-Chicago. Seeing that there would be no work for Teletype, it was decided
-to set up working quarters in Highland Park where the family lived.
-Since rented space was not available, a building was constructed on
-Lincolnwood Road in the Braeside section of Highland Park to house both
-the B. L. Kleinschmidt Printing Company and the machinery and other
-equipment of the Laboratories. The Laboratories, now inactive, became a
-personal holding company with 2300 shares to cover a book value of
-approximately $230,000.00 (Kleinschmidt having distributed the major
-portion of these shares to his children and grandchildren).
-
-Son Edward F. turned his thoughts to other fields and carried on
-experimental work in the new building in devices not connected with the
-telegraph. Son Bernard was involved in his printing business. Their
-father's thoughts lay dormant for a long time, but still there was the
-urge to continue with the telegraph, and a plan for operating a
-five-unit-code selecting mechanism, operating on a progressive stop
-principle to position a typewheel or to select a typebar for printing on
-tape or page, was worked out.
-
-When models of this new plan were completed and operating successfully,
-Edward E. Kleinschmidt immediately thought of Teletype Corporation and
-brought the apparatus to their attention, submitting models and patent
-applications for their evaluation. After numerous conferences and
-correspondence, however, his offer for the sale of patent rights and
-models was rejected. Discouraged, he left the completed models at the
-Highland Park lab and moved to Florida.
-
-During the second world war, son Bernard abandoned his printing
-establishment and started a tool and die shop, using the machinery and
-facilities of the Laboratories as well as space occupied by his printing
-shop. The B. L. Kleinschmidt Company was kept busy building tools, dies,
-and special devices for the war effort.
-
-Through Bernard's associations he learned that the United States Signal
-Corps needed a light-weight, transportable teleprinter for tactical
-field use, and he asked his father if he could show the progressive stop
-printer to the Signal Corps at their Chicago headquarters. His father,
-in Miami at that time, gave his approval. Two days later, the telephone
-rang in Miami and it was Bernard saying, "Dad, they are interested and
-want you to bring the printer model to Army Headquarters in Washington."
-Nothing could have pleased his father more!
-
-In February of 1944, Edward E. Kleinschmidt demonstrated a working model
-of his teleprinter in Washington at the office of the Chief Signal
-Officer. Officials of the Signal Corps were greatly interested in the
-unit, not only because of its extreme lightness and small bulk, but
-because of the representations that the basic design features of this
-tape printer, exclusive of the printing mechanism, could be incorporated
-in a page-type printer which could be constructed with a total weight of
-approximately thirty pounds. The machine was subsequently informally
-tested at the Signal Corps Engineering Laboratories and found to have
-excellent margins when working without an intermediate relay on very low
-line current, a highly desirable feature in a piece of tactical
-teletypewriter equipment.
-
-The exhibit at Headquarters was successful, and after operative tests at
-the Signal Corps' Coles Signal Laboratories in Red Bank, New Jersey,
-where approval for further studies was given, the Kleinschmidt
-organization was asked to prepare plans toward a tactical light-weight
-printer for field use.
-
-It should be pointed out that teletypewriters at that time were heavy,
-cumbersome, and intended for use only at telegraph offices or at other
-plant or office fixed installations.
-
-The plans for a light-weight page printer were submitted to the Signal
-Corps as requested and were well received by their engineers. These
-engineers then wrote up specifications detailing their requirements for
-a rugged, light-weight portable set for hand-carrying through jungles
-and swamps, and operable under severe climatic conditions; the
-specifications were submitted to the Teletype Corporation, the Western
-Union Telegraph Company, and to the Kleinschmidt organization. Western
-Union did not take on the development job, but Teletype and Kleinschmidt
-accepted. A contract for the development of a teletypewriter according
-to Signal Corps specifications was closed with both companies in 1945.
-
-The Kleinschmidt Laboratories were not in active operation at this time,
-so the first development contract was closed with the B. L. Kleinschmidt
-Company which was fully equipped to carry on the work. Expert tool and
-model makers were in his employ, some of whom turned out to do well at
-the drawing board and were of great help in working out mechanical
-functions. As a matter of fact, five or six of Bernard's employees are
-still with the Kleinschmidt Division of SCM Corporation at this writing,
-some having attained supervisory positions.
-
-Edward F. joined his father in further engineering and development work,
-and models of a typebar page printer and a typewheel page printer to
-operate at 60 words per minute were built. Upon evaluation by the Signal
-Corps and Army engineers, a printer with a higher operating speed, up to
-100 words per minute, was demanded. This new requirement meant a
-complete redesign of apparatus, but it was successfully carried through
-and experimental models were submitted by both companies. Thereupon both
-Kleinschmidt and Teletype were asked to build ten printers for field
-tests. This was done, and after extensive field testing, the
-Kleinschmidt-designed, keyboard-operated, 100-words-per-minute typebar
-page printer was accepted, and, by order of the then Secretary of War,
-it was made the standard for the Military, effective on January 1, 1949.
-(This printer was later to be known as the TT-4 tactical page printer,
-the principal component of Teletypewriter Set AN/PGC-1.) (See fig. 13.)
-
-An announcement from the Department of the Army, in a document released
-for publication on February 13, 1949,[16] read as follows:
-
- _Portable Teletypewriter Developed by Signal Corps_
-
- Portable teletypewriter equipment so light that a parachutist can
- carry it on a jump from an airplane has been developed and adopted by
- the Army, promising a major advancement in military communications,
- the Signal Corps announced today.
-
- Weighing but 45 pounds, compared with current field equipment that
- weighs 225 pounds, the new portable teletypewriter is but one-fourth
- the size of the old, has 300 fewer parts, is considerably stronger and
- consequently requires far less maintenance. The new equipment is
- capable of transmitting and receiving messages 66 per cent faster than
- existing types and will operate on both wire and radio circuits. It is
- waterproof and should it be used in amphibious operations, could be
- floated onto a beach.
-
- The development is the fruition of a 20-year-old project that did not
- get under way in earnest, however, until World War II was nearly over.
-
- Because of its light weight, the new teletypewriter can be used much
- closer to the front lines than has been the case. During World War II,
- teletyped messages could go only as far forward as a division
- headquarters. How much farther forward the new equipment can be used,
- will be determined in forthcoming field tests.
-
- The portable teletypewriter was developed by the Signal Corps
- Engineering Laboratories at Fort Monmouth, New Jersey, through a
- research and development contract with Kleinschmidt Laboratories,
- Incorporated, of Highland Park, Illinois.
-
- There are three components to a complete field unit: the
- teletypewriter itself, weighing 45 pounds; a power unit, and a case of
- accessories. The three together weigh 116 pounds. All units are
- waterproof, both to permit flotation in amphibious activities and to
- provide complete protection from weather. One man can carry the
- teletypewriter itself, while two men can carry all three units.
-
- The field teletypewriter in current use weighs 225 pounds and--if a
- vehicle is not available--requires four men to carry it. With power
- unit and accessories, present field equipment totals more than 400
- pounds and requires seven men to carry it.
-
-While development work for the Signal Corps was progressing, Bernard
-kept busy managing general operations and Edward F. took hold in the
-general design and devised important features that were patented in his
-name.
-
-Bernard died in March, 1948. However, development work went along with
-the B. L. Kleinschmidt facilities until 1949, when a production order
-for 2,000 teleprinters, conforming to the now approved Kleinschmidt
-design, was to be placed. Now that Bernard was no longer there to take
-over business details, and as a certain amount of basic capital was
-needed to operate a production establishment, arrangements were made to
-transfer Bernard's equipment to Kleinschmidt Laboratories which
-thereafter closed a contract to manufacture the required quantity of
-teleprinters now designated as the TT-4 telegraph typewriter.
-
-Kleinschmidt senior, now seventy-four, was not eager to take over the
-management of production activities, and while manufacturers in the
-office equipment and radio field were ready and anxious to take on the
-manufacture of these new teleprinters, he sought to keep the future of
-this new development with the Kleinschmidt Laboratories--now owned by
-all members of his family. His son-in-law, Emerson E. (Bud) Mead, was
-operating a manufacturing plant, producing electrical control devices
-quite successfully, so, "Why not ask Bud, then Secretary of Kleinschmidt
-Laboratories, to take over? He could no doubt sell the Mead company at a
-profit." Bud did find a buyer for his company and he was then made vice
-president of Kleinschmidt Laboratories; later, when Edward E.
-Kleinschmidt turned over full management to him, Mead became executive
-vice president.
-
-The immediate problem at the Laboratories was to find manufacturing
-space. The first thought was to rent, but then there would be no room to
-expand should larger orders follow, and this could be expected since
-Kleinschmidt teleprinter apparatus was now made standard equipment for
-all U.S. Armed Services. Upon further investigation, Bud Mead found a
-plot in Deerfield, Illinois, facing County Line Road, consisting of
-thirteen acres, which could be purchased at a reasonable price. This
-area would give plenty of building room and space for parking cars.
-Kleinschmidt Laboratories' first building, 200 x 150 feet, was soon
-erected.

-
-Preliminary work toward manufacturing, drawings, ordering of production
-machinery, special tools, standard parts, and other items was carried on
-at the Braeside laboratory.
-
-The efforts of all of the people of the Kleinschmidt organization,
-working with great enthusiasm and wonderful cooperation, sometimes
-around the clock, were rewarded when on April 17, 1950, preproduction
-samples of light-weight teletypewriter sets were delivered on schedule
-to the Signal Corps in Fort Monmouth for approval and acceptance.
-Immediately upon receipt of their approval, production began on the
-contract awarded in June of 1949.
-
-Kleinschmidt Laboratories subsequently received contracts and built
-thousands of their teleprinters, including the filling of orders for the
-AN/FGC-20 fixed station teleprinters (see fig. 14).
-
-Later, the Laboratories, together with the Automatic Electric Company,
-then of Chicago, now of Northlake, Ill., designed and built switching
-apparatus and set up high-speed, 100-words-per-minute, automatic
-teleprinter switching centers for the Military. These systems had trunk
-switching controls located at key distributing points in the United
-States and abroad, interconnected by microwave circuitry.
-
-As further orders for teleprinters and associated equipment came along,
-manufacturing facilities were expanded into more building area;
-additions to the first unit brought that building to 200 x 500 feet.
-Another building, 250 x 350 feet, of special design to house belt-line
-apparatus assembly and parts storage, also testing, inspection, and
-shipping, was erected in 1958.
-
-In August, 1956, Kleinschmidt Laboratories merged with Smith-Corona
-Inc., on an exchange-of-shares basis, which eventually gave Kleinschmidt
-Laboratories' shareholders 60 shares of Smith-Corona (later Smith-Corona
-Marchant Inc., and then SCM Corporation) stock for one share of
-Kleinschmidt Laboratories'. Bud Mead was elected a director and a member
-of the executive committee. Later, he became vice president of
-operations. When Smith-Corona merged with Marchant Calculators, Inc.
-(June, 1958), he was made executive vice president; then, in October of
-1960, he was named president of Smith-Corona Marchant Inc. (now known as
-SCM Corporation).
-
-Kleinschmidt, as a Division of SCM Corporation, continues to supply the
-Military and also commercial users with teleprinter equipment. The
-conclusion of this chapter tells briefly the direction the Kleinschmidt
-Division is going in the printed communications field.
-
-Before the Kleinschmidt 100-words-per-minute teleprinter was put into
-service on intercommunicating circuits, the operating speed on standard
-circuits had been limited to 60 words per minute. Noting this important
-change in operating speed, other manufacturers had to redesign their
-teleprinter equipment to meet the new 100-words-per-minute speed.
-
-Teletype Corporation came up with a new design, the No. 28, in which all
-the type pallets are moveably mounted in a rectangular box that is
-positioned to move a selected type pallet into printing position by a
-system of levers operated in aggregate motions under control of the code
-selecting mechanisms (fig. 15). When so positioned, a print hammer
-strikes the type pallet to print the character.
-
-Creed, in England, later brought out a new design, their No. 75, using a
-segmented typewheel having four rows of type faces. The typewheel is set
-in the selected printing position by a lever and linkage system
-operating in aggregate motion under control of the code selecting
-mechanism. To print the selected character, the typewheel is struck
-against the printing paper (fig. 16).
-
-Siemens and Halske, in Germany, produced their No. 100, a redesign of
-the No. 15 Teletype, using lighter and faster moving parts for operation
-at 100 words per minute. Among other improved features were a type bar
-shift to replace the platen shift for printing letters or figures, and a
-two-color ribbon which is automatically shifted to print in red or black
-to distinguish between sent and received messages--a feature of
-convenience in TELEX communication. The Siemens No. 100 was designed
-especially for the TELEX system, operating at 66 words per minute, where
-it is used extensively (fig. 17).

-
-The Kleinschmidt printer, designed to operate at 100 to 150 words a
-minute, employs a new method for operating a typebar printing mechanism,
-comprising a type basket movable across the printed page and carrying
-the required set of type bars. Each type bar has a connected push rod
-extending to the rear of the type basket and is made operative to cause
-printing when a rotating finger, selectively positioned by a coded stop
-cage, is struck against the push rod. To meet the requirements of the
-Military for a teleprinter operable in any angular position, the letter
-spacing and carriage return with deceleration to the stop position is
-under positive control of the motor drive.
-

- Military)]
-
-In 1948, scientists at Bell Telephone Laboratories, engaged in
-semiconductor research, announced the birth of their famous brainchild,
-the transistor. Now the little transistor and his friends, the diode and
-advanced techniques in electromagnetic inductive devices, have gradually
-taken over in the communications field, permitting startling speed
-increases and changes in equipment design.
-
-In the 100-words-per-minute teletypewriters, the permutation code
-equivalent of the character to be transmitted or received was at some
-point "set up" mechanically by positioning levers or vanes. The inertial
-properties of these mechanical parts placed low-level limitations on the
-operating set-up speed. By using the binary code and electronic
-switching circuits, the set-up time has been reduced from milliseconds
-to microseconds, making higher speeds more easily obtainable. Also,
-electronic approaches to printing on page or tape have contributed to
-the speed-up of telegraph receiving devices. Now, both tape and page
-devices are available at operating speeds up to 10,000 words per minute.
-
-Thanks to the Bell System, also, is the development of Data-Phone
-service, started in 1958. Data-Phone makes use of all the telephone
-switching devices and repeating apparatus so that any type of
-communicating system using frequencies within the voice range may be
-used. For such systems the telephone company will install equipment to
-separate the different types of electrical transmission to prevent
-interference. Because Data-Phone enables not only the sound of the human
-voice to be sent over a telephone circuit, but information from a
-teletypewriter or business machine as well, this new use for the
-telephone system has expanded its service to many types of business
-communications. At this writing, the Bell System advertises, "Data-Phone
-'talks' 16 times faster than people talk. It can send punched card or
-taped data anywhere--at speeds up to 2500 words per minute."
-
-While these advances have been taking place, the transistor and its
-companions have made a similar impact in the field of data processing.
-The rapid evolution of computers and other high-speed switching devices
-has generated a need for higher speed equipment to supply input and
-output requirements. The changeover to electronics has realized
-minification, lighter weight, reduction of mechanical parts with a
-corresponding reduction in maintenance, quieter operation, and greater
-adaptability to code and language conversion.

- KLEINSCHMIDT DIVISION OF SCM CORPORATION
-
-At the Kleinschmidt Division where Mr. Emilio J. Cadamagnani, Executive
-Vice President, is in charge, their engineering department, under the
-supervision of Mr. Robert L. Kearney, is keeping up with the change from
-electromechanically- to electronically-controlled devices. Their new
-Model 311 Electronic Data Printer shown here is an example. Operating at
-speeds from 60 to 400 words per minute and capable of receiving 5-, 6-,
-7-, or 8-level code information in either serial or parallel form, it is
-designed for use in high-speed communications or data processing
-systems.
-
-Also illustrated is still another new Kleinschmidt device, the Model 321
-Automatic Data Set, which includes not only a page printer with keyboard
-but a tape perforator and a tape reader, all compactly mounted in a
-console.
-
-Both the Model 311 and Model 321 are compatible with existing data
-modems, conventional printing telegraph equipment, electronic computers,
-and data processing equipment. This compatibility permits their use in
-on-line or off-line communications and data-handling applications.
-
-More exciting devices may be anticipated in the rapidly moving field of
-printed communications.

-computers including obsolete, old, middle-aged and new computers. It
-exists because of the efforts of hundreds of volunteers and donations
-from people in all walks of life.
-
-Volunteers and financial support to provide volunteers with the
-assistance they need are critical to reaching Project Gutenberg-tm's
-goals and ensuring that the Project Gutenberg-tm collection will
-remain freely available for generations to come. In 2001, the Project
-Gutenberg Literary Archive Foundation was created to provide a secure
-and permanent future for Project Gutenberg-tm and future
-generations. To learn more about the Project Gutenberg Literary
-Archive Foundation and how your efforts and donations can help, see

-Section 4. Information about Donations to the Project Gutenberg
-Literary Archive Foundation
-
-Project Gutenberg-tm depends upon and cannot survive without wide
-spread public support and donations to carry out its mission of
-increasing the number of public domain and licensed works that can be
-freely distributed in machine readable form accessible by the widest
-array of equipment including outdated equipment. Many small donations
-($1 to $5,000) are particularly important to maintaining tax exempt
-status with the IRS.
-
-The Foundation is committed to complying with the laws regulating
-charities and charitable donations in all 50 states of the United
-States. Compliance requirements are not uniform and it takes a
-considerable effort, much paperwork and many fees to meet and keep up
-with these requirements. We do not solicit donations in locations
-where we have not received written confirmation of compliance. To SEND
-DONATIONS or determine the status of compliance for any particular
-state visit www.gutenberg.org/donate
-
-While we cannot and do not solicit contributions from states where we
-have not met the solicitation requirements, we know of no prohibition
-against accepting unsolicited donations from donors in such states who
-approach us with offers to donate.
-
-International donations are gratefully accepted, but we cannot make
-any statements concerning tax treatment of donations received from
-outside the United States. U.S. laws alone swamp our small staff.
-
-Please check the Project Gutenberg Web pages for current donation
-methods and addresses. Donations are accepted in a number of other
-ways including checks, online payments and credit card donations. To
-donate, please visit: www.gutenberg.org/donate
-
-Section 5. General Information About Project Gutenberg-tm electronic works.
-
-Professor Michael S. Hart was the originator of the Project
-Gutenberg-tm concept of a library of electronic works that could be
-freely shared with anyone. For forty years, he produced and
-distributed Project Gutenberg-tm eBooks with only a loose network of
-volunteer support.
-
-Project Gutenberg-tm eBooks are often created from several printed
-editions, all of which are confirmed as not protected by copyright in
-the U.S. unless a copyright notice is included. Thus, we do not
-necessarily keep eBooks in compliance with any particular paper
-edition.
-
-Most people start at our Web site which has the main PG search
-facility: www.gutenberg.org
-
-This Web site includes information about Project Gutenberg-tm,
-including how to make donations to the Project Gutenberg Literary
-Archive Foundation, how to help produce our new eBooks, and how to
-subscribe to our email newsletter to hear about new eBooks.

-<h2>PREFACE</h2>
-<p>Having been associated with the printing telegraph for more than
-sixty years, I have felt the urge to write a r&eacute;sum&eacute; of the problems and
-the progress made during my time toward today&rsquo;s wonderful achievements
-in the art of telegraphic communications.</p>
-<p>It is interesting to note that of all the old-time electric telegraph
-systems, it appears that only those using the Morse dot-dash code
-invented in 1837 and the permutation code devised by Gauss and
-Weber in 1833 (now known everywhere as the Baudot code) have
-survived today.</p>
-<p>Samuel Morse&rsquo;s code, which was modified somewhat in several letter
-code compositions to facilitate its use anywhere in the world, has become
-an audible, easily learned international language, loved by its users
-everywhere. It will no doubt continue to be used for some time to come,
-as long as we have our railroad telegraph operators, radio amateurs, police
-CW systems, certain branches of the Armed Forces, and any others
-who converse in dits and dahs.</p>
-<p>The permutation code has taken hold firmly, too. Its use of five pulses
-transmitted in varying combinations of on and off, or positive and
-negative, conditions has wide application in today&rsquo;s printed communications
-systems. As in the Morse system, alphabets for the five-unit permutation
-code system have been modified as to letter code compositions for
-international correspondence. The permutation code uses the powers of
-two in progressively selecting a letter printing position.</p>
-<p>The binary code uses the same selective stops by yes or no designation
-in a system of counting by the powers of two. It is used where larger
-groups of yes or no positions are required, as in data processing and
-computer systems.</p>
-<p>This writing, then, is a bit of history that will put together the constructive
-developments that brought about the present era of the worldwide,
-telegraphically-transmitted printed word.</p>
-<p>I wish to acknowledge with great appreciation the informative
-material sent to me by my friends, both here and in foreign lands, who
-are associated with the telegraph industry.</p>
-<p>For assembling information we have gathered from various sources
-and for the most helpful assistance given me in writing this story, I also
-want to thank my secretary, Mrs. Doris Pompilio.</p>

-<br />A NEW ERA BEGINS</h1>
-<h2 id="c1">CHAPTER 1
-<br />Introduction</h2>
-<p>It is a major effort today to keep pace with the rapid advances in the
-field of printed communications. Hardly a day passes that we do not read
-of a new development in equipment that is more complex, farther reaching,
-more rapid in operation....</p>
-<p>This electrical, or electronic, transmission and interchange of the
-printed word might be said to be an evolvement of the old printing telegraph
-systems. Such systems, over the years, while not so rapidly as today,
-were also improved upon, modified, speeded up, but could be used only
-in the point-to-point transmission of messages.</p>
-<p>While the railroads had been using the Morse code system (key and
-sounder) satisfactorily, they would have preferred a system whereby a
-printed record could be obtained. In the industrial world, too, there was
-need for a businessman&rsquo;s printing telegraph&mdash;a means to type out messages,
-directly and interchangeably, to far-off associates. And there was
-always that dream, starting with the earliest telegraph experimenters, of
-being able to correspond instantly with one another anywhere in the
-world. Indeed, the need for all this had been known for many years, but
-not the way.</p>
-<p>It was after the turn of the century that telegraph engineers began in
-earnest to think about a system of telegraphy that would permit direct
-intercommunication by the printed word, and direct circuit connection
-to any outlying subscriber as in the telephone communication system.</p>
-<p>Up until then, apparatus for transmitting telegrams, such as that of
-Wheatstone &amp; Cooke, Morse, Hughes, Barclay, etc., also the step-by-step
-stock tickers and bulletin printers, used various types of code-signaling
-devices in which the code varied in length as to the transmission
-of more frequent or less frequent letters.</p>
-<div class="pb" id="Page_2">2</div>
-<p>Now in order to provide a practical telegraph system permitting the
-interconnection of apparatus throughout the world, the first basic requisite
-is a standard signaling code; this code, moreover, must be of such
-nature as to use the simplest form of electrical signaling (such as make
-and break signals, or positive and negative signals), and the code should
-be of equal length for all characters.</p>
-<p>The permutation code, where combinations of five plus and minus
-pulses will give thirty-two selective positions, was suggested as far back
-as 1833 by Gauss and Weber. Whitehouse, in 1854, and Barnett, in
-1860, experimented further, using the permutation code to operate a
-recording mechanism. However, no practical means for actually printing
-letters and figures was found until 1882 when Jean Maurice Emile
-Baudot designed a multiplex system to permit the transmission of four
-messages in each direction over a single line circuit. Later, Baudot designed
-a tape printer in which the selecting and printing mechanisms
-comprised an ingenious arrangement of cooperating parts, including a
-rotating typewheel associated with a coded combiner wheel and five
-stationary elements selectively movable to received code positions, each
-element having an extending finger to be brought into contact with the
-periphery of the coded combiner wheel upon the completion of a selective
-code setting. When the code combination of the set fingers matched a
-code on the wheel, a print roller was released to press the recording tape
-against the typewheel and print the selected letter.</p>
-<p>Although the Baudot Multiplex was used extensively in Europe, engineers
-and inventors in the United States had not produced a practical
-5-unit permutation-code teleprinter system. They were constantly searching
-for a unit code system requiring a minimum number of electrical
-impulses to operate a telegraph printer. Various types of relay systems
-using distinctive signal pulses were proposed. A three-unit-code system
-that showed promise, and did not require synchronism, used four different
-electrical pulse conditions: a high voltage positive or negative pulse,
-and a low voltage positive or negative pulse. Records show that many
-inventors played with this code and that John Burry, C. L. Krum, G. A.
-Cardwell, and J. C. Barclay, among others, built operable equipment
-using such a code arrangement. The following excerpt from Cardwell&rsquo;s
-patent No. 905,497 of December 1, 1908, may be of interest. It describes
-the code arrangement of four different line conditions in three signal
-groups to produce 36 different code combinations.</p>

-<p>Cardwell&rsquo;s backers formed the American Telegraph Typewriter Company
-and sold shares, claiming a great profitable future for their apparatus.
-A few printers were built, but, on extended service tests, the high-low-voltage
-feature proved to be impractical and the company folded.</p>
-<p>J. C. Barclay of the Western Union Telegraph Company designed
-printing apparatus and perforated tape transmitting equipment for this
-type of system, but, after limited use of the high-low-voltage principle, he
-changed this feature to long and short pulses with discriminating relays.
-With later improvements, this system was put into service on a number
-of Western Union message circuits.</p>
-<blockquote>
-<p><i>Note:</i> Today, in the 1960s, the techniques of frequency division and
-electronics could be used for transmitting three different line conditions
-from a group of four different frequencies. In such a system, synchronism
-between send and receive terminals, or the start-stop method to control
-correct timing, is not needed. The transmission of any selected group of
-three, when received in succession at a teleprinter, will cause printing of
-a letter when the third receiving relay completes a circuit to the selected
-printing magnet. Transistor circuits with associated control elements could
-replace the relays.</p>
-</blockquote>
-<p>Telegraph companies in the United States were mostly using the
-Morse and increased its efficiency through development of quadruplex
-operation and high-speed transmission systems. However, the quest for
-a more efficient printing telegraph system persisted and various types
-were proposed and tried. All made use of codes that were impractical for
-intercommunicating systems and, while some were used in message service
-<span class="pb" id="Page_4">4</span>
-by the telegraph companies, they did not appear to have any great
-advantage over the Morse telegraph.</p>
-<p>In 1911, Western Union began investigating systems used in Europe.
-The first to be tested was the Creed, a system for transmitting and printing
-Continental or Morse code signals at high speed. After observing
-several other systems, the Murray Multiplex, an improved and modernized
-version of the Baudot Multiplex, was found to show better operating
-features and, due to the use of the five-unit permutation code, more
-efficient use of telegraph lines.</p>
-<p>By agreement with Donald Murray, and with his cooperation, the so-called
-Western Union Multiplex was developed, using Murray&rsquo;s phonic
-wheel drive and synchronous correction. Western Union engineers designed
-tape transmitters and an autocontrol device for transmitting service
-signals. A keyboard-operated, five-unit-code, tape punch was supplied by
-the Morkrum Company. A page printer, which was later converted to
-print on gummed tape, was supplied by the Kleinschmidt Electric Company.
-The Western Union Multiplex was effective in increasing operating
-efficiency and came into extensive use throughout the system.</p>
-<p>From that time on, development of the Baudot permutation-code printing
-telegraph apparatus was furthered by various companies, such as Bell
-Laboratories, Western Electric, the Morkrum Company, the Kleinschmidt
-Electric Company, as well as the companies of J. E. Wright, L. M. Potts,
-and others.</p>
-<p>It appears that all of these inventors experimented with the idea of
-operating all transmitting and receiving apparatus at identical speeds to
-transmit a five-unit-code combination by first transmitting a pulse to
-start both transmitter and the distant receiver at the same time. Synchronous
-operation was obtained by electric motors equipped with governors
-to maintain correct speed; some used tuning-fork-controlled impulse
-motors. A system of five relays with progressive contact arrangements to
-cause cascade operation was also used to provide correct timing. Later,
-when correctly-timed, 60-cycle alternating current became available (see
-<a href="#Page_27">page 27</a>), synchronous motors did the job.</p>
-<p>Teleprinter apparatus using this synchronous method worked very
-well for point-to-point transmission as was used by the telegraph companies
-and news-distributing organizations to carry local traffic. It did
-not, however, solve the sought-for plan for a teleprinter intercommunicating
-<span class="pb" id="Page_5">5</span>
-system. When attempts were made to connect printers at different
-distant points in a telegraph intercommunicating circuit while using the
-synchronous principle, false reception and printing errors would occur,
-due to variation in line circuit conditions and to a variation of the mechanical
-start operation at outlying teleprinters. This required frequent
-overline adjustment to keep the connected apparatus in phase.</p>
-<p>The following is an excerpt from a patent application of Dr. Louis M.
-Potts (later to become research engineer for the Morkrum-Kleinschmidt
-Corporation), filed June 17, 1909, giving his idea for achieving a teleprinter
-intercommunicating system on the synchronous principle. Dr.
-Potts was a very capable telegraph engineer. His early association was
-with the telegraph system of the Rowland Telegraphic Company which
-had limited use in the early 1900s.</p>
-<blockquote>
-<p>In those synchronous telegraph systems wherein the sending and the
-receiving commutator brushes constantly rotate, it is necessary to adjust
-these brushes so that they will approximately simultaneously engage
-corresponding segments. To effect this adjustment there is usually provided
-a special device embodying an additional segment on each commutator,
-and the adjustment consists in causing the brushes to arrive
-approximately simultaneously on this segment at the two ends of the line.
-Such adjustment is known as &ldquo;finding the letter&rdquo; and has to be made every
-time synchronism has been interrupted. According to the present invention,
-the necessity of providing additional means for performing the so-called
-operation of &ldquo;finding the letter&rdquo; is rendered unnecessary, since the transmitting
-and receiving commutator brushes at the two ends of the line
-start up afresh as it were for each signal.</p>
-</blockquote>
-<p>In a later patent application, filed October 11, 1913, Dr. Potts stated:</p>
-<blockquote>
-<p>This machine has also the advantage of being able to operate with a
-very short code. In order to adapt it to Morse circuits, it should be capable
-of operating with a code at least as short as the Morse code. In the present
-machine, I preferably employ a five unit code which, together with the
-starting impulse and the lag between signals, is actually shorter than the
-Morse code. Counting the five code impulse periods, the starting impulse
-period and the period of lag between impulses, each signal in my case,
-may be considered in comparison with the Morse code as being seven
-units long, whereas the Morse code is 8.5 units long. The average signal
-being shorter than the Morse, the delicacy of adjustment will be less and
-the distance of operation greater than a Morse telegraph for the same rate
-of transmission in words per minute.</p>
-</blockquote>
-<p>Dr. Potts, however, still depended on like synchronous operation at
-both terminals, and dual start, so he did not have the answer after all!</p>
-<div class="pb" id="Page_6">6</div>
-<p>John E. Wright, who in the 1890s designed and built step-by-step
-printing apparatus, including the Wright-Negron bulletin printer, also
-turned his thoughts toward the five-unit permutation code for printer
-operation and built several variations using the synchronous principle.
-The Superintendent of Telegraphs for the Delaware, Lackawanna and
-Western Railroad thought well of Wright&rsquo;s apparatus and placed some in
-operation. But, here again, reliable operation could be maintained only
-in point-to-point operation. As will be noted in <a href="#c3">Chapter 2</a>, Mr. Wright&rsquo;s
-patents were purchased by the Kleinschmidt Electric Company in 1922.</p>
-<p>A paper issued by Siemens-Halske of Germany in January of 1917<a class="fn" id="fr_1" href="#fn_1">[1]</a>
-states that the Siemens Pendel Telegraph &ldquo;is among the forerunners of
-the eventual worldwide start-stop system for intercommunication by the
-printed word.&rdquo; The following excerpt translated from that description
-briefly explains the operation:</p>
-<blockquote>
-<p>The Pendel Telegraph uses the five-unit permutation code to select
-characters, and operates on a start-stop principle. It is intended for station-to-station,
-one-way operation, the line current normally being closed to
-the positive side of the line battery. Transmission is under control of a
-keyboard with keys arranged as in a typewriter. Upon the depression of
-a key, the line battery is reversed, thereby transmitting a negative pulse
-to line which effects the start of both transmitter and receiver at the same
-time. Thereafter, five-code-combination pulses are transmitted, followed
-by positive current to line, thus restoring the circuit system to a normally
-closed line condition.</p>
-<p>The name &ldquo;Pendel Telegraph&rdquo; would make one think that the timing
-of the transmitter and receiver were under control of a swinging pendulum.
-This is not the case. However, it does have a plan for simulating the
-action of a pendulum by an arrangement of springs and semi-rotating
-weights to effect synchronism for each printing cycle; and energy is derived
-from a motor which intermittently winds a power mainspring to an even
-tension. This arrangement is started in operation at both terminals at the
-same time and provides isochronal motion at both transmitter and receiver
-for each transmitted character. Due to multiple operations of the springs
-and weights used to provide synchronous action, the operating speed is
-limited to four or five letters per second.</p>
-</blockquote>
-<p>In England, too, there was work being done along these same lines.
-Mr. H. H. Harrison, who is so well known for his contributions over the
-years in the telegraph field, devised printer apparatus using the five-unit
-<span class="pb" id="Page_7">7</span>
-code which is described in Herbert&rsquo;s <i>Telegraphy</i>,<a class="fn" id="fr_2" href="#fn_2">[2]</a> as follows:</p>
-<blockquote>
-<p>The instrument is provided with a Baudot 5-key keyboard, and has
-a step-by-step distributor which is mounted inside the casing. The standard
-Baudot alphabet is used, but each letter or character is prefixed by a
-positive starting impulse. Every time a key is depressed a universal bar is
-actuated which closes contacts giving the starting impulse and the distributors
-at both ends of the line step through six spaces. The combiner
-is of the electrical type invented by Baudot, and is similar to that used in
-Siemens&rsquo; new automatic printing telegraph. Five relays of the class
-used for telephone purposes are set at the receiving end, according to
-whether some of the stepping impulses are positive or negative. The
-distributor is a trunk hunting switch as used in automatic telephony, and
-consists of a ratchet wheel and stepping electromagnet. On the shaft of
-the ratchet wheel is fixed a wiper which sweeps over a semi-circular bank
-of contacts in response to the stepping impulses. Two-way working is
-secured by means of the differential balance.</p>
-<p>(The article ends with the statement that a typewriter keyboard
-is being constructed to replace the five keys.)</p>
-</blockquote>
-<p>It appears that all of these telegraph engineers and inventors envisioned
-a start-stop system and experimented with the idea of operating all transmitting
-and receiving apparatus at identical speeds by inserting a start
-signal before each group of letter code signals, to start both transmitter
-and distant receiver at the same time, and a stop condition between code
-groups.</p>
-<p>In the following chapters will be shown the contributions made by
-both the Kleinschmidt and the Morkrum companies in the printing telegraph
-field, and finally their joint efforts which were to lead up to the
-establishment of that now worldwide intercommunicating system, the
-TELEX.</p>

-<h2 id="c2">CHAPTER 2
-<br />KLEINSCHMIDT</h2>
-<p>Edward E. Kleinschmidt&rsquo;s first direct contact with telegraph apparatus
-was during his employment as a young man, in 1893, by John E. Wright,
-whose firm had developed and was then manufacturing printing telegraph
-equipment known as the Wright-Negron bulletin printer for the
-Havas News Agency in Paris. These printers operated on the step-by-step
-principle at 30 words per minute. (To attest to their ruggedness, as late
-as 1951 some of these machines were reported to be still in use!)</p>
-<p>Five years later, in 1898, Kleinschmidt started an experimental shop
-at 122 Fulton Street in New York City. A sign over the door read, &ldquo;Inventions
-Developed,&rdquo; and he did experimental and developmental work
-for various customers (individuals as well as companies&mdash;including Western
-Union) on a time-and-material basis. In the beginning he had a
-project of his own going&mdash;a facsimile telegraph system. He submitted the
-system to Western Union in 1900 with the suggestion that it might be
-valuable for customer services, since a customer could write his telegram
-in longhand and insert the written message in the transmitting unit for
-transmission in facsimile to the telegraph central. The idea, however,
-was rejected. At that time the photoelectric cell for scanning the written
-message and electronic means for amplifying signals had not yet been
-developed; while the apparatus operated quite well over short circuits,
-evidently the time had not arrived for commercial facsimile telegraphy.</p>
-<p>The first telegraph apparatus job for the shop was brought in by Dr.
-George A. Cardwell, a dentist by profession. It was a partially developed
-printing telegraph using a three-unit code made up of combinations of
-plus-minus-high-and-low-voltage pulses (the code we have already discussed).
-The work for Dr. Cardwell was carried on until 1903 when a
-working model was completed. It had a typewheel for printing and stops
-arranged in a circle; magnets under control of relay selection were used
-to set the stops according to the received code combinations. This arrangement
-operated well, and on a test over a Western Union circuit from
-New York to Baltimore it gave satisfactory results. As we have seen,
-<span class="pb" id="Page_9">9</span>
-however, the code arrangement proved unsatisfactory for general telegraphic
-use.</p>
-<p>Many customers came to the experimental shop with every type of idea
-imaginable; vacuum cleaners (The &ldquo;Vacuna&rdquo;), elevator signals, some
-early designs for Elmer Sperry&rsquo;s gyrocompass were only a few. Kleinschmidt
-also set up a couple of side-line businesses, one for manufacturing
-automatic fishing reels under the trade name &ldquo;Kelso,&rdquo; another, the Aseptuloid
-Company, for making vaccination shields (some readers may well
-remember their childhood vaccinations being protected by a bubble of
-celluloid).</p>
-<p>Another customer was George M. Seely, who later was instrumental in
-bringing Kleinschmidt&rsquo;s work to the attention of Charles B. Goodspeed
-and W. S. Moore (they were to become his financial backers&mdash;see <a href="#Page_14">page 14</a>).
-Mr. Seely came to the shop in 1906 with a partially developed
-block system for electric trolley car railways. His plan was to use special
-devices attached to the trolley pole which would cooperate with stationary
-electrical controls at certain fixed points along the road.</p>
-<p>After working along these lines for awhile it became apparent that
-some inventive work would be required on Kleinschmidt&rsquo;s part. Seely, in
-addition to time and material, then offered him a retainer for the assignment
-of any resulting patents.</p>
-<p>As plans and studies progressed, a number of railway signaling devices
-were developed, tested, and patented. A major item was the development
-of a telephone train dispatching system. A complete set of apparatus was
-exhibited in operation at the American Association of Railroads Communications
-Convention held in Los Angeles in 1910. The company
-name given this venture was the &ldquo;National Telephone Selector Company,&rdquo;
-located at 235 Greenwich Street, New York City. The telephone
-train dispatching system was installed on the Long Branch Railroad with
-30 stations connected with dispatcher headquarters at Red Bank, New
-Jersey. Another installation was made on the Baltimore and Ohio Railroad
-in West Virginia, connecting 38 stations with dispatcher headquarters
-at Fairbanks, West Virginia.</p>
-<p>Most of the patents assigned to Mr. Seely were eventually sold to the
-Hall Signal Company.</p>
-<p>Doing development work for others and assigning patents for a retainer
-<span class="pb" id="Page_10">10</span>
-did not satisfy Kleinschmidt&rsquo;s ambitions. His interests being mainly in
-the telegraph, he set out to design and build a piece of apparatus that the
-telegraph companies could use. A keyboard-operated perforator to punch
-the Morse code in a tape for automatic transmission at high speed looked
-like a promising subject, since the tape punches in use at that time had
-a three-key arrangement&mdash;one each for dot, dash, and space.</p>
-<p>Kleinschmidt&rsquo;s first keyboard-operated, Morse-code perforator was constructed
-in 1911 and exhibited to the Western Union Telegraph Company.
-Mr. G. R. Benjamin, their chief engineer, and Mr. Emmett R.
-Shute, a vice president, thought well of the machine and, after testing it,
-gave Kleinschmidt an order for fifty. This order spelled success. To
-celebrate the event, Kleinschmidt invited his brothers, Bernard, Fred and
-William, and their families to a dinner party at a distinguished restaurant.
-Soon thereafter (1913), the Kleinschmidt Electric Company was
-organized, with the brothers as incorporating officers.</p>
-<p>The Kleinschmidt Keyboard Perforator came into use by telegraph and
-cable companies throughout the world where Morse, Wheatstone, or
-Cable codes were used to transmit telegrams. It was also used with
-Western Union&rsquo;s Barclay system which had its own code. The device
-was later manufactured by Teletype Corporation under the name &ldquo;Teletype
-Perforator&rdquo; and used by the U. S. Government where it served its
-purpose for high-speed Morse transmission during the war period (see
-<a href="#fig1">figure 1</a>).</p>
-<p>In the years 1911 and 1912, the Western Union Telegraph Company,
-in looking toward higher operating efficiency over their trunk circuits,
-decided to test the Creed high-speed Morse and the Murray Multiplex,
-and invited both companies to bring their apparatus to New York. It was
-on this occasion that Kleinschmidt became acquainted with Mr. F. G.
-Creed, who, upon observing the Kleinschmidt keyboard perforator at
-Western Union, was impressed by its performance and said that there
-would be a good market for it in England, especially as a keyboard
-punch for the Creed high-speed Continental-Morse-code system. As a
-result of that conference he asked for ten as a trial order. These perforators
-were shipped to London in due time and gave satisfactory service.
-The British Post Office Telegraph evidently had heard about this new
-perforator and sent a letter to the Kleinschmidt company asking for a
-demonstration at their London headquarters.</p>
-<div class="pb" id="Page_11">11</div>
-<p>Now it happened at that time that Kleinschmidt was extremely busy
-with the development of a five-unit-code typebar printer for the new
-Multiplex&mdash;and this was urgent since the first model was to be put on
-competitive test with a typewheel printer submitted by L. M. Potts and
-the Western Electric typewheel printer which was then in use. Therefore,
-he felt he should not lose a month or two in this developmental
-work for a trip to London. So, his answer to this important invitation
-was that he could not personally bring one of his perforators for exhibit
-but that he would ask Mr. F. G. Creed to do so. Mr. Creed agreed and
-set up a formal exhibit for the Post Office engineers; he consequently
-received an order for twenty Kleinschmidt perforators. Further correspondence
-with Creed resulted in an order for one hundred and a request
-that Kleinschmidt come to London the next year (1914) to negotiate a
-contract to supply his keyboard perforators for the Creed high-speed
-Morse and to set up a sales agency with Creed for certain territories.</p>
-<p>While in London in the summer of 1914, Kleinschmidt visited the
-Managing Director of the Post Office Telegraph at his office to apologize
-for having had Mr. Creed exhibit the Kleinschmidt perforator instead
-of bringing it personally as had been requested. The Managing Director
-replied that Mr. Creed had indeed given a very good operating exhibition
-of the device and that an order for twenty had been placed with him.
-&ldquo;However,&rdquo; he added, &ldquo;you know, we sent you an official invitation and
-expected your appearance with your machine!&rdquo;</p>
-<p>To continue: Upon observing the change in systems at Western Union
-(switching from the Barclay to the Murray Multiplex), the Kleinschmidt
-Electric Company, who had been experimenting in the development of a
-telegraph typewriter, built a receiving teletypewriter for the multiplex. It
-was a magnet-operated, five-unit-code typebar page printer, using the
-Underwood typewriter mechanisms as a basis; and it was completed in
-time for test and evaluation at Western Union in competition with the
-typewheel printers of both L. M. Potts and Western Electric.</p>
-<p>The Western Electric machine was given the number 1A, Mr. Potts&rsquo;s,
-2A, and the Kleinschmidt printer was 3A. The final outcome of the tests
-was the selection of the Kleinschmidt model, and the company received
-an order for five machines, to include a spare, to equip the New York
-terminal of a New York-to-Boston, four-channel multiplex system. The
-order was filled in a short time and the machines were put on test.</p>

-<div class="pb" id="Page_13">13</div>
-<p>Kleinschmidt watched the operation of his machines in service almost
-every day and was continually on the lookout for possible ways to improve
-and simplify the apparatus. The tests ran through to completion satisfactorily,
-and, upon submitting an improved design, numbered the 3B,
-the Kleinschmidt Electric Company received an order for one hundred
-typebar page printers. The 3B thereafter became standard apparatus and
-additional orders were placed as the multiplex system at Western Union
-expanded (see <a href="#fig2">figure 2</a>).</p>
-<p>Several years later, Western Union efficiency engineers found that, due
-to circuit failures, certain parts of messages would have to be repeated.
-Because this meant retyping the message, they felt, and for other reasons
-as well, that printing the received messages on tape would be more economical,
-since corrections could be inserted without repeating the entire
-message. To meet this requirement, the typebar page printer was redesigned
-for printing on tape. This was accomplished by using the same
-selection controls and operating the typebars to print downward on the
-tape instead of upward against the platen as in the page printer. A tape
-gummer to attach the tape to a message blank was also designed. The
-21A, later No. 22, tape printer was ordered in quantity thereafter.</p>
-<p>Seeing the possibility of using their typebar page printer for direct-line
-service, the Kleinschmidt company built a motor-driven send-receive unit
-having a single contact transmitter which operated under control of a
-code-perforated tape to transmit seven signals in succession: one start,
-five code, and a stop signal. The receiving unit had a seven-segment
-commutator, one segment for start, five for code, and one for stop, and a
-rotating brush to pick up and transmit the received code signals to the
-printing unit. This apparatus was installed at the United Press for news
-distribution to their connected newspapers. Another set was installed at
-the Louisville and Nashville Railroad for station communications, and
-still another in New York City at the Equitable Life Assurance Society
-between their downtown and uptown offices. In connection with the
-latter installation, the Equitable people asked permission to install the
-printing apparatus on the telephone line and there was objection from
-the telephone company. However, after some consideration they finally
-agreed that the apparatus could be installed but warning that should it
-create interference with the telephone line it would be removed immediately.
-As it turned out, the printer operation over this telephone circuit
-<span class="pb" id="Page_14">14</span>
-did not create any interference and the apparatus remained in service a
-long time (<a href="#fig3">figure 3</a>).</p>

-<p>The Kleinschmidt Electric Company now began to have financial difficulties.
-Edward Kleinschmidt was borrowing wherever he could. There
-was no large quantity production and evidently his charges for the apparatus
-delivered were too low. At any rate, early in 1917, Mr. Seely suggested
-that he get financial help to carry on and it was here that the
-following gentlemen entered the picture: Charles B. Goodspeed of the
-Buckeye Steel Casting Company; Paul M. Benedict, assistant to the
-president of the C. B. &amp; Q.; Edward Moore, son of Judge Moore of the
-American Can Company; Eldon Bisbee, a New York lawyer; and one of
-Mr. Bisbee&rsquo;s clients, Albert Henry Wiggen, who was then president of
-the Chase National Bank. With their financial backing, the company
-was able to continue with further developmental work on simplified and
-<span class="pb" id="Page_15">15</span>
-more efficient apparatus. Orders for various types of equipment for the
-Western Union Multiplex and for the Morse code keyboard perforator
-came along, but developmental costs were high and still more capital
-investment was required; Kleinschmidt would then borrow from the
-Chase Bank. Every so often at the Kleinschmidt company&rsquo;s directors&rsquo;
-meetings, Mr. Holly, cashier of the bank and also a director of the company,
-would state that the Kleinschmidt loan &ldquo;stood out like a lighthouse,&rdquo;
-so a vote for an additional stock issue was carried and the loan
-paid.</p>
-<p>Along about 1919 the Kleinschmidt company had completed a satisfactory
-keyboard-operated typebar teleprinter for intercommunication
-systems (see <a href="#fig4">figure 4</a>). The Kleinschmidt Telegraph Typewriter, as it
-was called, was installed at the New York City News, the Panama Canal,
-and at the Brooklyn Union Gas Company (<a href="#fig5">fig. 5</a>).</p>
-<p>In 1922, Edward Kleinschmidt, having learned that Mr. J. E. Wright
-had discontinued further developments in the telegraph field, proposed
-the purchase of his patents, stating that this acquisition would broaden
-the Kleinschmidt company&rsquo;s patent situation. The proposal was carried,
-and, after negotiations, Mr. Wright&rsquo;s patents were bought for 100 shares
-of the Kleinschmidt Electric Company&rsquo;s common stock.</p>
-<p>In 1923, the Kleinschmidt Telegraph Typewriter was exhibited at the
-20th Annual Business Show in New York and created a great deal of
-interest. In 1924, a complete telegraph system was engineered and set
-up for the Mexican government. (An engineer from Western Union
-was borrowed to help with this job.)</p>
-<p>One day, in 1923, after some correspondence with Samuel Samuel &amp;
-Co., Ltd., through whom the Kleinschmidt company received orders
-from Japan for the Morse code keyboard perforator, the Japanese Telegraph
-Administration sent one of their telegraph engineers, Mr. Y. Okomoto,
-to the company&rsquo;s headquarters to assist in working out a keyboard
-arrangement of Japanese characters for a simplified alphabet consisting of
-88 characters which the Japanese Telegraph Administration had devised.
-The five-unit code could not be used since only 64 selective positions
-could be had. So the telegraph typewriter mechanisms were changed to
-six-unit-code operation, which worked out very well. The Kleinschmidt
-company, and later Morkrum-Kleinschmidt, received continuing orders
-for the six-unit-code telegraph typewriters.</p>

-<br />KRUM AND MORTON
-<br />(MORKRUM)</h2>
-<p>Mark Morton, head of the Western Cold Storage Company in Chicago,
-and cold-storage engineer Charles L. Krum, the vice president of
-the firm, entered the telegraph field quite by accident. A young electrical
-engineer named Frank Pearne, in 1902, had some ideas for a printing
-telegraph machine and needed financial backing to carry on his experiments.
-One of his contacts happened to be Joy Morton, the founder of
-the Morton Salt Company. Joy Morton became interested enough to
-become Pearne&rsquo;s backer, and prevailed upon brother Mark to set up a
-laboratory in the attic of the cold-storage plant for Pearne&rsquo;s experiments.</p>
-<p>It seems that after a year or so, Pearne lost interest in his invention
-and went into the teaching field. He proved to be a very successful professor
-at Armour Tech where he remained until his death.<a class="fn" id="fr_3" href="#fn_3">[3]</a> But Pearne&rsquo;s
-work was not in vain, for Charles L. Krum had become intensely interested
-and carried on the work with further inventions of his own. Indeed,
-he filed his first patent application on August 20, 1903, which proposed
-the use of a code comprising four signals: a positive pulse or a negative
-pulse of low voltage, and a positive or negative pulse of a higher voltage.
-Four additional patents were filed, the last in 1906.</p>
-<p>C. L. Krum then set about building a machine which was demonstrated
-in 1906 and looked promising enough to form a company to further
-develop it. This company was made up of the Mortons (brothers Joy and
-Mark) and the Krums (Charles L. and his son Howard who had just
-finished college). The combination of their names, of course, resulted in
-&ldquo;The Morkrum Company,&rdquo; which was incorporated in the State of Maine
-on October 7, 1907. The charter stockholders were Joy Morton, who
-shouldered the greatest financial burden; Charles Krum; Joy Morton&rsquo;s
-secretary, Daniel Peterkin (he later became an officer of the Morkrum
-Company); Mark Morton; and Sterling Morton (Joy&rsquo;s son, of whom we
-<span class="pb" id="Page_18">18</span>
-shall be hearing more later on). The working capital of the new company
-amounted to $150,000.00.</p>
-<p>Charles Krum&rsquo;s son Howard, after graduation, joined with his father
-in the developmental work of this new company and, due to his studies
-in electrical engineering, was able to help his father considerably. His
-first love and intended career was music, but he put this aside in favor
-of his father&rsquo;s telegraph printer. However, a tune on the piano which he
-always kept in the laboratory would help him solve many a difficult
-problem.</p>
-<p>In 1908 the Krums developed and produced a working model of the
-four-unit-code, plus-minus, high-low-voltage system, which was applied
-to operate the mechanism of an Oliver typewriter. The system was then
-given an operative test on the wires of the Chicago and Alton Railroad,
-of which Joy Morton was a director.</p>
-<p>As their research work progressed, Howard studied the various systems
-in current use and, with his father, decided to abandon the plus-minus,
-high-low-voltage system. They turned instead to a system using the five-unit
-permutation code as employed by Baudot in his multiplex telegraph
-in which synchronized terminal apparatus with periodic correction was
-the controlling feature.</p>
-<p>Their first joint patent describes a plan for accomplishing synchronized
-reception with transmission using a system of five relays interconnected
-to operate in successive cascade form; thus, when the relays at both
-terminals are correctly timed for successive operation, they will transmit
-and receive the five pulse combinations of the Baudot code. For transmitting
-and receiving the code pulses, each of the five relays has an
-additional contact. To start the relay cascade operation, a start relay is
-added at both terminals and operated by a start pulse which precedes each
-code transmission. It seemed natural for the Krums to turn to a relay
-system at first, since, from his work with the three-unit-code, high-low-voltage
-system, C. L. Krum was experienced with the possibilities of
-relay operation.</p>
-<p>The system of the relay chain in cascade operation was employed to
-operate a page printer using the mechanisms of the Blickensdoerfer typewriter
-which had a three-row typewheel. The Postal Telegraph Company
-became interested and bought a number of these printers in 1910. This
-was the first sale of Morkrum apparatus and provided enthusiasm for the
-<span class="pb" id="Page_19">19</span>
-Krums for further research, which led to the substitution of a governed-motor-driven
-brush distributor to replace the relay cascade system. For
-this new plan the motor at the receiving printer operated at a slightly
-higher speed and was held in continuously synchronous operation with
-the transmitter by the periodic transmission of a correcting pulse. The
-new code selecting and printer control system was also adapted to operate
-the mechanism of the Blickensdoerfer typewheel typewriter. The idea
-worked out better than the cascade relay system, and a number of printers
-using this method were constructed and named the &ldquo;Morkrum Blue
-Code.&rdquo; A few were put in service at the Postal Telegraph Company.</p>
-<p>The Associated Press (AP) became interested in the Morkrum &ldquo;Blue
-Code&rdquo; printer system as a replacement for the low-speed Morse system
-which was being used to transmit news items to newspapers in many
-cities. Here, continuous transmission under control of a code-punched
-tape, as used in the Morse code system, was a requirement, so Messrs.
-Krum set to work and designed a keyboard-operated, five-unit, Baudot-code
-perforator and an automatic punched-tape-controlled transmitter.
-This apparatus was installed at the New York headquarters in 1915 and
-receiving printers were gradually installed throughout the Associated
-Press system. The following excerpt and picture (<a href="#fig6">fig. 6</a>) from Oliver
-Gramling&rsquo;s book, <i>AP&mdash;The Story of News</i>,<a class="fn" id="fr_4" href="#fn_4">[4]</a> describes the introduction
-of the system to the Associated Press:</p>
-<blockquote>
-<p>The tide of news by telegraph had continued with the years. Facilities
-had been improved, the Morse clicked into virtually every town in the
-country, but the old method was the same. Day in and day out, sending
-operators took dispatches, translated them into the dash-dot of code, and
-the telegraph keys sent the signals on the circuits at a rate of twenty-five
-to thirty-five words a minute. In member newspaper offices along the line
-the Morse sounders clack-clacked busily and receiving operators translated
-the code symbols back into words, copying the stories in jerky spurts.
-The news of more than half a century had been handled that way.</p>
-<p>For some time, however, Charles L. Krum, a Chicago cold-storage
-engineer, and his son Howard had been working to perfect an automatic
-machine which would send the printed word by wire at greater speed
-without the intermediary of code. They called their invention the Morkrum
-Telegraph Printer&mdash;coining the word Morkrum by combining the inventor&rsquo;s
-name with the first syllable in the last name of Joy Morton, a
-Chicago businessman who financed them.</p>

-</div>
-<blockquote>
-<div class="pb" id="Page_21">21</div>
-<p>Several other automatic telegraphic devices were being promoted, but
-(Kent) Cooper and engineers in the Traffic Department decided
-Krum&rsquo;s machine held the most promise for their purposes. Tests got under
-way. In the Associated Press headquarters, which had been moved seven
-blocks from the old Western Union building to 51 Chambers Street, a
-sending operator sat at a keyboard similar to that of an ordinary typewriter.
-As he struck the keys, copying the dispatches before him, the machine
-perforated a paper tape with a series of holes, each combination representing
-a letter. The tape fed into a box-like transmitter which transformed
-the tape perforations into electrical impulses and sent them along the wires
-into the receiving machines in newspaper offices. These impulses actuated
-telegraph relays and set the receiving Morkrum machines automatically
-reproducing the letters which the sending operators were typing miles away.</p>
-<p>The tests demonstrated that the Morkrum could transmit news hour
-after hour at the rate of sixty words a minute and the copy was delivered
-clean and uniform. Thus began the slow extension of Morkrum transmission
-to the whole leased wire system, replacing the &ldquo;brass pounding&rdquo;
-Morse keys. It was a transition that required years and until it was completed
-both Morse and Morkrum worked side by side in many places.</p>
-</blockquote>
-<p>An interesting story appeared recently in &ldquo;The AP World,&rdquo;<a class="fn" id="fr_5" href="#fn_5">[5]</a> giving
-some recollections of AP&rsquo;s first field maintenance man, Royal (Roy)
-Bailey, then aged 71 and living in retirement in California. He still remembers
-the AP&rsquo;s first printing telegraph machines, the article says; in
-fact, he helped make them, for he was a mechanic in the Morkrum
-Company&rsquo;s factory in Chicago. When the Morkrum Company shipped
-the first machines to AP headquarters, Bailey went along with the machines
-to install and maintain them, although he remained on the Morkrum
-Company&rsquo;s payroll. He eventually installed AP printers all over
-New York City and Connecticut, in Newark, Philadelphia, Baltimore
-and Washington, and in Chicago, St. Louis and Kansas City. He recalls
-that Morse telegraphers &ldquo;used to groan when they first saw him.&rdquo; The
-early teleprinters were hard to keep synchronized, Bailey further recalls,
-and copy boys had to check the speed frequently by sighting the striped
-motor flywheel through a tuning fork. (Many of those copy boys, he says,
-including Mickey Burt and Henry Elling, became AP engineers.)</p>
-<p>As the experimental and developmental work continued at the Morkrum
-plant, Howard Krum studied all types of start-stop systems and found
-that synchronous control was the basis of all systems. After experimenting
-with various ideas his thoughts turned to a plan to make the start of the
-<span class="pb" id="Page_22">22</span>
-receiving unit somewhat independent of the transmitting unit start, thus
-avoiding irregularities then present in transmitter start devices. This idea
-led to the construction of a permutation-code, start-stop system, using
-segmented commutators with rotating brush distributors at both transmitting
-and receiving units and a start magnet for each to control start-stop
-operation.</p>
-<p>In this system the transmitter start magnet, when energized, releases
-the transmitting brush, which immediately contacts the first segment to
-transmit a start pulse to operate the receiver start magnet; the five-unit-code
-signal combination follows and both transmitting and receiving units
-are stopped. The apparatus was applied to control the selecting and printing
-mechanism of the Blickensdoerfer typewheel typewriter and named
-the &ldquo;Morkrum Green Code.&rdquo; This improved apparatus soon replaced the
-Blue Code printer at Associated Press and other installations (see figs.
-<a href="#fig7">7</a> and <a href="#fig7A">7A</a>).</p>
-<p>In this connection the following additional comments of Mr. Bailey
-may be of interest:<a class="fn" id="fr_6" href="#fn_6">[6]</a></p>
-<blockquote>
-<p>In 1919 I installed the New York-Washington circuit, with drops at
-Philadelphia and Baltimore. This was a new type of printer using what
-we called the Green Code. This was considered an improvement over the
-old Blue Code, which meant a rearrangement of the receiving mechanism,
-but still the machines made use of a typewheel....</p>
-<p>Our biggest job of all came in 1923 when we changed over all the
-old Blue Code typewheel printers in the New York area to the new style
-L. C. Smith typebar printers using Green Code. (Morkrum bought L. C.
-Smith typewriters and added new machinery to them. Those printers became
-the famous Model 12.)</p>
-</blockquote>
-<p>As we have seen, a number of inventors had patented ways and means
-to adopt the five-unit code for operating a telegraph printer system by
-the transmission of a start pulse to start both transmitting apparatus and
-the distant receiving apparatus at the same time, followed by transmission
-of a selected code and a stop pulse. To achieve successful operation, very
-close speed adjustment was required. At first, this was achieved by the
-use of governed motors and, later, when accurately timed, 60-cycle alternating
-current became available, the problem of synchronous operation
-of send and receive stations was solved by the use of synchronous motors.</p>

-<p>Telegraph printer systems of this type were used by telegraph companies
-for city-to-city transmission of telegrams and by news-gathering
-and -distributing organizations to transmit the news from headquarters
-to newspapers in different cities. While start-stop systems of this type were
-used successfully on press circuits and on telegraph message station-to-station
-circuitry, trouble was experienced when a number of printer send-receive
-units were set up in an intercommunicating system. Here it was
-found that the receiver start was not always in time with the transmitter
-start, due to varying line circuit conditions and a variation in the start
-release mechanism at connected stations.</p>
-<p>It seems odd that synchronous systems, where both transmitter and
-receiver were started at the same time (requiring both transmitter and
-receiver to maintain synchronism), held the field for so long a time, thus
-limiting telegraph transmission to one-way operation.</p>
-<p>It evidently took a mind not bound or hampered by the standard and
-accepted way of operating synchronous systems to discard such old
-ideas and to set forth boldly on a new pattern which, in reality, differed
-but slightly from the then-established synchronous systems, and to sow
-the seed for starting further developments leading to the present telegraph
-typewriter, TWX, and TELEX intercommunicating systems. Such
-a man was Howard L. Krum, who, in further thinking on the subject,
-came upon the almost simple idea of having the transmitter start the
-receiver rather than having them both start at the same time. This
-arrangement required higher speed operation of the receiver and therefore
-the receiving code pulse positions were spread over a shorter area,
-which meant progressively decreasing the angular division of the
-receiving members. Then, to set the received start pulse in the most
-favorable position with relation to the following code signal reception,
-an orientation adjustment of the receiver start position was provided.</p>
-<p>(Note: On June 20, 1961, Kleinschmidt wrote to Howard Krum&mdash;then
-in retirement in California&mdash;giving a short description of the
-Morkrum Company activities, including the wording of the above last
-two paragraphs, and asking him to write the Morkrum story. Howard
-Krum replied on July 3, 1961, indicating his approval and saying that
-he would be glad to put together some notes for Kleinschmidt. It was
-quite a shock, therefore, when a letter was received from Howard
-Krum&rsquo;s son, Charles, in September of 1961, telling of his father&rsquo;s sudden
-serious illness. Then, regretfully, it was not long afterwards that
-<span class="pb" id="Page_25">25</span>

-<p>Howard Krum&rsquo;s improved method for operating start-stop, permutation-code

-starting to produce permutation-code, start-stop telegraph printers using
-typebar printing like the more modern typewriters which began rapidly
-to replace the Blickensdoerfer, the Hammond, and the other typewheel
-printing typewriters. Observing this situation, the Morkrum Company
-started intensive development work to produce the No. 12 typebar page
-printer, using the typebars and operating mechanism of the L. C. Smith
-typewriter and platen of a Woodstock typewriter (<a href="#fig8">fig. 8</a>).</p>
-<p>Further developments produced the Morkrum No. 11 tape printer

-<span class="pb" id="Page_26">26</span>
-characters under control of start-stop, send-receive devices. The No. 11

-<p>The new No. 12 typebar page printer found numerous applications.
-It replaced the Green Code and the earlier Blue Code wherever used.
-The new No. 12 was installed at Western Union, on some railroads, and
-in the Chicago Police telegraph system. The No. 12s were also installed
-by Postal Telegraph on intercity circuits and used as receiving units
-for the Postal Multiplex. The Postal Multiplex had been designed by
-Morkrum and Postal engineers with the consultant assistance of Donald
-Murray who was a friendly associate and had a license agreement with
-the Morkrum Company covering some of his patents. A few No. 12
-Morkrums were shipped abroad for use with the Murray Multiplex; the
-British Post Office Telegraph and the Australian Telegraph Administration
-were customers.</p>
-<div class="pb" id="Page_27">27</div>
-<p>Late in 1924 the Morkrum Company and the Kleinschmidt Electric
-Company joined to form the Morkrum-Kleinschmidt Corporation. A story
-telling of the union of these two companies was published by <i>Fortune</i>
-magazine in March of 1932.<a class="fn" id="fr_7" href="#fn_7">[7]</a></p>
-<p>Before going to that story, it may be of interest to describe an important
-event concerning the change in the supply of electric power from direct
-current to 60-cycle alternating current and the final timing to exactly 60
-cycles per second of all A.C. power supplies so that our electric clocks may
-be connected to an A.C. outlet and give correct time.</p>
-<p>The advent of correctly timed, 60-cycle A.C. electric power, available
-throughout the nation, was a great boon to the designers of printing telegraph
-apparatus and some types of facsimile telegraph and picture transmitting
-systems. In prior years, overline synchronization of send and
-receive apparatus was always a problem and never perfect. Today, synchronizing
-apparatus between terminals becomes the simple matter of
-providing 60-cycle A.C. synchronous motors. Just plug into a power outlet
-and you have &ldquo;sync&rdquo;!</p>
-<p>Henry Ellis Warren, a clock maker, noting the change in electric power
-service from direct current to 60-cycle alternating current, set about to
-build a motor to operate at 60-cycle speed but found that the 60-cycle
-frequency did not always hold to form, and when applied to running a
-clock, did not hold correct time.</p>
-<p>The following excerpt, from <i>The Romance of Time</i>,<a class="fn" id="fr_8" href="#fn_8">[8]</a> tells of
-Warren&rsquo;s activities which led to synchronizing 60-cycle alternating
-current to exact time:</p>
-<blockquote>
-<p><span class="center"><i>Synchronous Electric Time</i></span></p>
-<p>One of the most important of all contributions to horology is the work
-of an American who has earned the title, &ldquo;Father of Electric Time.&rdquo;</p>
-<p>Henry Ellis Warren was graduated from Massachusetts Institute of
-Technology in 1894. In 1907 he married and settled in Ashland, Massachusetts.
-Here it was that he began to work out his idea for electrically
-operated timepieces.</p>
-<p>His first product was an ingenious battery-operated clock. In 1914 he
-organized the Warren Clock Company and set up production in a barn
-on his farm. Yet he knew the battery clock was not his goal, for direct
-current offered no means of accurate regulation. Direct current flows constantly
-<span class="pb" id="Page_28">28</span>
-in one direction only, like water down a river or like the passage
-of time. On the other hand, alternating current changes direction regularly,
-like the oscillation of the balance wheel in a watch. But instead of the
-usual five times a second of the balance wheel, most alternating current
-completes its trip forward and backward sixty times a second. Obviously,
-a clock &ldquo;geared&rdquo; to such a frequency would run as reliably as the current.</p>
-<p>In 1916, after several years of extensive experimentation, Warren developed
-a motor which would start by itself, run on alternating current,
-and carry without difficulty the load of reduction gears driving the clock
-hands. It could also handle the cams and contacts of an alarm clock or
-set in motion a striking or chiming mechanism.</p>
-<p>Then came the test. He plugged the clock into the power socket. It
-commenced to run. Weeks of observation and checking showed an irregular
-error of as much as ten to fifteen minutes a day.</p>
-<p>Convinced that his clock was right, Warren discovered that the alternating
-current frequency delivered to his barn factory was off half a cycle
-per second&mdash;59&frac12; and not 60 cycles. This slight deflection would produce
-that much time loss in a 24-hour run. When he informed the electric
-company of this error, he was met at first with polite disbelief. Yet he
-showed such a comprehensive knowledge of the subject that the company
-began to recheck their standards.</p>
-<p>Warren built several more synchronous clocks and a master regulator
-of his own design for power-station use. On one dial of his master clock
-there were two hands, black and gold. The black hand was connected to
-an accurately adjusted pendulum clock, beating seconds. The gold hand
-was driven by the gear train of one of his electric clocks. As long as
-the two hands revolved together, the current cycles were exactly 60
-per second. Set up in a power station, this allowed the operator to adjust
-the turbine generators as needed to keep the two hands of the master
-clock together. Thus all other properly set electric clocks on the same
-system would keep the same time automatically.</p>
-<p>The Edison Electric Illuminating Company of Boston tried out the
-master clock on October 23, 1916. Since then this regulation has continued.</p>
-<p>Other power companies adopted Warren&rsquo;s master clock. Today virtually
-all alternating current furnished in America is similarly checked. Practical
-electric time is available at the light socket almost everywhere. But there
-are additional benefits.</p>
-<p>Standardizing the frequency expanded the market for current to run
-the increasing number of clocks in use. Yet, from the consumer&rsquo;s point
-of view, each clock draws little current, costing but a few pennies a month.
-Uniform frequency also gave more even speeds in motor-driven machinery,
-with a resultant improvement in product. It made easier the joining of
-<span class="pb" id="Page_29">29</span>
-one power station to another. Synchronous motors used in certain meters
-and recorders produced better, more accurate records at lower cost.</p>
-<p>The Warren enterprise expanded rapidly. The battery clock was discontinued.
-The red barn was no longer large enough, and new space was
-acquired. The trade mark &ldquo;Telechron,&rdquo; meaning &ldquo;time from a distance&rdquo;
-(from two Greek words), was used to identify all products of the company.
-The firm name was changed to stress the name Telechron, and in 1952 a
-merger was made with the General Electric Company. Plants are now
-operated in Worcester as well as in Ashland, Massachusetts.</p>

-<h2 id="c4">CHAPTER 4
-<br />Morkrum-Kleinschmidt Corporation
-<br /><span class="small">(later renamed &ldquo;Teletype Corporation&rdquo;)</span></h2>
-<p>During and after the first world war, both the Morkrum Company and
-the Kleinschmidt Electric Company were progressively developing and
-producing telegraph apparatus and bringing out new and improved operating
-devices to a point where conflicting patents were at issue. This meant
-infringement litigation which might destroy both companies. Neither
-company could obtain orders in sufficient quantity to make the manufacturing
-of apparatus profitable, and, with costly development work at hand,
-more capital investment was a continuous requirement.</p>
-<p>The following excerpts from the March 1932 issue of <i>Fortune</i><a class="fn" id="fr_9" href="#fn_9">[9]</a> tells of
-the final joining of the two companies.</p>
-<blockquote>
-<p>The Morkrum Co. had no profits to show for its efforts, and one can be
-fairly safe in assuming that no other maker of telegraph printers made
-profits. There were competitors, of course. Even the first telegraph invented
-by Samuel Morse had a printer, but it printed in dots and dashes instead
-of in letters of the English alphabet. That original Morse printer was
-abandoned as far back as 1844 because a man who could be trained to read
-dots and dashes could just as easily be trained to listen to them. The problem
-of getting a printer to print the alphabet was faced by inventors more
-than half a century ago, and it was not really a difficult problem. The difficulty
-was to invent a printer that was not too complicated and delicate to be
-reliable, that was simple enough to be manufactured for a few hundred
-instead of a few thousand dollars.</p>
-<p>This difficulty occupied many minds other than the Morton-Krum intelligences.
-The most noteworthy of Morkrum Co.&rsquo;s rivals in printer-making
-was Edward Kleinschmidt, an inventor who had all the inventor&rsquo;s legendary
-devotion to his task and to nothing else. His creations included a vaccination
-shield, an automatic fishing reel, and the perfection of the Wheatstone
-perforator. He had been tinkering with a telegraph printer in one form and
-another since the beginning of the century. In 1917 his project was revamped.
-It had the financial backing of Charles B. Goodspeed, of the Buckeye
-Steel Casting Co.; Paul M. Benedict, assistant to the president of the
-C. B. &amp; Q.; Edward Moore, son of Judge Moore of American Can fame;
-<span class="pb" id="Page_31">31</span>
-Eldon Bisbee, a New York lawyer; and one of Mr. Bisbee&rsquo;s legal clients,
-Albert Henry Wiggin, then president of the Chase National Bank. It was
-Mr. Goodspeed, a quiet, retiring gentleman, who supplied most of the corporate
-(as distinct from inventive) energy of the Kleinschmidt Electric Co....</p>
-<p>In the years from 1917 to 1924 the Kleinschmidt and the Morkrum
-companies became the leading makers of telegraph printers, but they did
-not have an easy row to hoe. Their only possible customers were the two
-great telegraph companies, the Telephone company, the railroads, and an
-occasional outside business such as a press association. The competition was
-disheartening, and it became keener with the elevation of Sterling, son of
-Joy Morton, to the presidency of the Morkrum Co., an elevation that was
-mainly a War-time accident, for Sterling Morton had resigned from his
-father&rsquo;s company to enlist in the Army, had been rejected because of a
-small steel plate in his anatomy, and had chosen the Morkrum Co. as an
-alternative. Engineering progress was made, sometimes under ludicrous
-circumstances.</p>
-<p>There was one occasion when Sterling Morton, about to sail for Europe,
-heard that the Kleinschmidt Co. was about to bring out a simplex printer.
-Up to that time both companies had been making printers for use with
-multiplex machines. Mr. Morton was afraid that Mr. Kleinschmidt was
-about to anticipate him in the simplex development which was the forerunner
-of the present teletypewriter. This was a contingency which Mr.
-Morton could not well permit. On the spur of the moment, he called on
-Howard Krum, who happened to be in New York. They bought a drawing
-board, hired a room at the Princeton Club, and worked for twenty-four
-hours trying to design such a machine. Completely baffled by one small
-detail, they gave up and took a bus for Coney Island. On the way, Howard
-Krum doubled up in sudden ecstacy and inspiration. They rushed from the
-bus at Coney Island, entered a soda fountain, and on the spot designed the
-machine on the back of an envelope. This simplex machine of the Morkrum
-Co. and the one developed by Kleinschmidt at the same time are the machines
-which make Teletype commercially important, the substance of the
-business today.</p>
-<p>But engineering progress was not business progress. Both companies from
-the standpoint of profits were failures. Their few customers played them off
-against each other. In despair, they were both willing to sell out. At one
-point Mr. Goodspeed offered the Kleinschmidt company to Mr. Newcomb
-Carlton of Western Union for $412,000, the amount invested in it. Mr.
-Morton sold his company in all but fact to Mr. Charles G. du Bois, then
-president of Western Electric, but Mr. du Bois went off to Europe, and his
-substitute refused to see any merit in the deal. So it fell through. Unable
-to sell themselves to their customers, they tried selling themselves to each
-other. In 1923 Messrs. Goodspeed and Morton came to terms. The Morkrum
-Co. signed the agreement and, everything arranged, Mr. Goodspeed
-<span class="pb" id="Page_32">32</span>
-went off to bicycle with his wife in South Africa&mdash;whereupon his company
-suddenly changed its mind.</p>
-<p>That was the situation of these two unfortunate companies in 1924 when
-Mr. Morton started a suit for patent infringement against his rivals. A
-counter suit was promptly filed. Mr. Goodspeed was quite right when he
-said the suits would ruin both&mdash;there was every prospect that by the time
-the courts had settled things, the patents would have been in such a snarl
-that neither could do anything. The suit, in fact, was Sterling Morton&rsquo;s
-way of bringing matters to a head. So, figuratively speaking, on the courthouse
-steps they merged.</p>
-<p>The terms of the merger as embodied in the six-line agreement (it was
-later made over into a twenty-five-page legal document which concluded
-by saying that in case of dispute the six-line agreement should be the final
-authority) were these: each of the old companies received a half interest
-in the common stock (10,000 shares) of the new company; 15,000 shares
-(callable at 105) of the new company&rsquo;s preferred stock should be divided
-according to the assets of the old companies. Actually, 13,979 shares of
-preferred were issued, the majority going to the Morkrum group.</p>
-</blockquote>
-<p>And so it was that the agreement to join both companies under the
-name Morkrum-Kleinschmidt Corporation was consummated and chartered
-in the State of Delaware on December 29, 1924, with Sterling
-Morton as President, Howard L. Krum as Vice President in charge of
-manufacturing, and Edward E. Kleinschmidt as Vice President in charge
-of development, patents and foreign sales.</p>
-<p>One of the first decisions to make was whether the Kleinschmidt plant
-in Long Island City or the Morkrum plant in Chicago would be the headquarters
-for the new company. The Kleinschmidt company was on a
-27,000-foot leased floor in a building which R. H. Macy Company had
-just purchased to use for a warehouse, and negotiations had been going
-on for some time for the purchase of the Kleinschmidt lease&mdash;the sum of
-$25,000.00 having been offered. When the union of the two companies
-was decided upon, an agreement to vacate on the terms offered was
-signed, and the Kleinschmidt firm moved to the Morkrum-owned plant
-in Chicago.</p>

-<span class="btc">Morkrum-Kleinschmidt Corporation No. 14 Start-Stop Typebar Tape Printer</span><span class="btr small"><i>Picture through courtesy of Teletype Corporation</i></span></p>
-</div>
-<p>Bringing together the engineering talent and patents of the two companies
-had an immediate effect toward further progress. The first thing
-the new company set out to do, through consolidation of their past efforts,
-was to perfect a satisfactory start-stop-operated tape printer for the Western
-Union Telegraph Company to use for circuit extension to customers
-who were extensively using the telegraph for immediate, written communication.
-(This was to speed up telegraphic communication and eliminate
-the need for messenger service which had been the custom.) The
-Morkrum company had submitted their start-stop-operated Baudot tape
-printer, and the Kleinschmidt company had proposed the Western Union
-No. 22 tape printer in a redesign to start-stop operation. Now, the new
-company was able to combine both plans and as a result came up with
-their first development, a typebar, start-stop-operated, tape printer, the No.
-14 (see <a href="#fig10">figure 10</a>). In the final design, Howard Krum and his production
-engineers took a large part. After tests and evaluation, Western Union&rsquo;s
-first order was for 10,000 machines at $317.00 each. This amounted to a
-total of $3,170,000.00. No such quantity had ever been heard of before!</p>
-<div class="pb" id="Page_34">34</div>
-<p>It is quite evident that while the two companies were separated, each
-coming up with improved and new designs of telegraph apparatus, there
-was a lack of decision by telegraph companies as to which type of apparatus
-to adopt in expanding their operations, and therefore they did
-not buy in quantity. The largest previous order to the Kleinschmidt Electric
-Company was for 800 No. 22 typebar tape printers for the Western
-Union Multiplex.</p>
-<p>At Morkrum-Kleinschmidt more space was needed. The corner property
-on Wrightwood Avenue adjoining the Morkrum plant was purchased,
-and a four-story building was erected.</p>
-<p>The design of a telegraph typewriter that would be more efficient and
-require a minimum of maintenance service was the most important project,
-and Morkrum-Kleinschmidt was working with Bell Laboratories engineers
-endeavoring to meet all the requirements of the Bell Telephone
-system. A typebar printer with a stationary printing platen and moving
-typebar printing unit was specified. These requirements were finally met
-with the design of the No. 15 page printer to operate at 60 words per
-minute, and manufacture of this apparatus was started in 1927 (see <a href="#fig11">figure 11</a>).
-The No. 15 page printer became the standard for nationwide intercommunicating
-telegraph service for many years.</p>
-<p>In 1926, soon after the No. 14 tape printer was put into service,
-Morkrum-Kleinschmidt received a request from the police department of
-Berlin, Germany, for detailed information, stating that they were interested
-in the purchase of about sixty No. 14 printers. The letter asked if
-Morkrum-Kleinschmidt was represented by an agent in Germany whom
-they could contact. At an executive meeting, Mr. Morton and Mr. Krum
-asked Mr. Kleinschmidt to take care of this matter since his company,
-before joining them, had sold apparatus in some foreign countries. After
-further correspondence with the Berlin police officials, Kleinschmidt decided
-personally to take a No. 14 printer to Germany and arrange for a
-representative there. After visiting and conferring with several companies
-experienced in the telegraph and associated apparatus field, a satisfactory
-arrangement was consummated with the C. Lorenz Company, on October
-25, 1926, for the manufacture and sale of Morkrum-Kleinschmidt
-equipment in Germany, on a royalty-licensing basis. At that time the
-Lorenz company manufactured telegraph and telephone equipment and
-railway signaling apparatus. Their engineering department was under the
-supervision of Dr. Gerhard Grimsen who took the matter in hand for
-further exploitation toward an intercommunicating printing telegraph
-system, using the No. 15 page teletypewriter. Siemens &amp; Halske, the
-principal manufacturers of telegraph equipment in Germany, were also
-licensed by the Morkrum-Kleinschmidt Corporation, on June 1, 1929,
-with the consent of the Lorenz company.</p>

-</div>
-<div class="pb" id="Page_36">36</div>
-<p>(As may be seen in the <a href="#c6">following chapter</a>, it was these licensing arrangements
-which led to the establishment of the TELEX intercommunicating
-teleprinter system in Europe.)</p>
-<p>In early 1927 the well-known newspaper publisher, Mr. Frank E. Gannett,
-came to Morkrum-Kleinschmidt, bringing his company&rsquo;s engineer,
-Mr. Walter Morey, who had heard of various attempts to operate a typesetting
-machine, such as Linotype or Intertype, directly from the telegraph.
-Mr. Gannett said, &ldquo;We have telegraph typewriters in our news
-rooms that record the news as transmitted from the Associated Press and
-the United Press, and that is fine. Now, why not go a step further and
-operate our typesetting machines directly from the telegraph circuit? If
-you can develop such a device, I will help finance the project.&rdquo;</p>
-<p>Indeed, after some study of the matter, the possibility of devising such a
-system seemed entirely feasible and the development of suitable apparatus
-was turned over to the research and development department. A workable
-plan was soon put together and a separate company, the Teletypesetter
-Company, was organized, with Mr. Gannett joining financially.
-Edward Kleinschmidt was elected president. Development proceeded and
-a complete set of apparatus was set up and publicly demonstrated for the
-first time on December 6, 1928, at one of Mr. Gannett&rsquo;s newspapers,
-<i>The Times Union</i> of Rochester, New York. Teletypesetter equipment
-was subsequently manufactured for several installations. After the Western
-Electric Company purchased the Teletype Corporation in 1930, the
-Teletypesetter Company was sold to the Fairchild Company. Teletypesetter
-equipment is now in universal use by most newspapers and the
-larger printing companies.</p>
-<p>During the period that the United States&rsquo; business cycle was on a
-continuous upswing (during the late 1920s), securities sales on the New
-York Stock Exchange were going to constantly higher volume, and the
-old step-by-step stock ticker did not, by large margins, keep pace in recording
-stock share transactions. There was a cry for a higher speed stock
-<span class="pb" id="Page_37">37</span>
-ticker; in fact, the Stock Exchange officials told Morkrum-Kleinschmidt
-that they would be happy to convert the entire system if they could get
-higher speed.</p>
-<p>An adaptation of the five-unit-code, start-stop system seemed the solution
-and the Research and Development department set out to develop
-suitable apparatus. Several ideas were studied and, because of the frequent
-changes from letters to figures, requiring printing in separate rows
-on the tape, a six-unit code was adapted instead in which combinations for
-a figure included the sixth selecting pulse to operate the figures print
-hammer and block the letters print hammer.</p>

-<span class="btc">Morkrum-Kleinschmidt Corporation Stock Ticker</span><span class="btr small"><i>Picture through courtesy of Teletype Corporation</i></span></p>
-</div>
-<p>The Morkrum-Kleinschmidt company was soon able to show the Stock
-Exchange people a stock ticker operating on a telegraph system that
-<span class="pb" id="Page_38">38</span>
-worked at twice the speed of the step-by-step-operated tickers then in use.
-A speed of 500 printing operations per minute could be obtained, thus
-attaining a one-hundred-percent increase in the transmitting and recording
-of stock quotations on the tape (see <a href="#fig12">figure 12</a>). The Stock Exchange
-ticker service company ordered 15,000 of these high-speed tickers and the
-Western Union Telegraph Company also ordered a quantity for their
-national stock quotations distributing systems.</p>
-<p>As business of the combined Morkrum and Kleinschmidt companies
-went along, it was thought that the name &ldquo;Morkrum-Kleinschmidt
-Corporation&rdquo; was a pretty big mouthful and that a simpler name more
-characteristic of its products would be better. The name &ldquo;Teletype&rdquo; was
-suggested, and in the year 1928 the name change to &ldquo;Teletype Corporation&rdquo;
-was made. The exact origin of the word &ldquo;teletype&rdquo; is not known but
-it is no doubt one of the abbreviated forms of the words &ldquo;telegraph typewriter&rdquo;
-which were used over the years. In literature, in the early 1900s,
-we find that the word &ldquo;teletype,&rdquo; in speaking of printing telegraph equipment,
-and other shortened forms, such as &ldquo;telewriter&rdquo; and &ldquo;teletyper,&rdquo;
-were used interchangeably.</p>
-<p>Kleinschmidt&rsquo;s son, Edward F., who studied electrical engineering at
-Steven&rsquo;s Institute and at Northwestern University, was employed as development
-engineer by the Morkrum-Kleinschmidt company where he
-assisted in the design of projects at hand, and, during 1929, produced a
-system and apparatus for transmitting and recording printed characters by
-the successive transmission of dots arranged in a pattern to form letters.
-While this system required a higher signaling frequency, it was thought
-to be superior to permutation-code transmission over radio circuits where
-electrostatic interference is experienced, since, in the dot pattern transmission,
-electrostatic interference up to a degree will not change the readability
-of a transmitted letter.</p>
-<p>The system was in test operation to prove its efficiency over radio circuits
-where considerable static interference was experienced. Upon hearing
-of this new telegraph for the radio, Mr. R. Stanley Dollar became
-interested in the use of this communicating system for his steamship
-line. There was considerable correspondence in this matter during mid-1930,
-just prior to the sale of Teletype; however, neither AT&amp;T nor
-Western Electric was interested in further promoting this new radio
-telegraph, so the matter was dropped.</p>
-<div class="pb" id="Page_39">39</div>
-<p>Business activities of Teletype Corporation were now growing rapidly
-and with good profit. The capital structure of 10,000 shares was wholly
-inadequate, so by a 15-to-1 stock dividend the capital structure was raised
-to 150,000 shares, and dividends on an annual basis of $12.00 were paid.</p>
-<p>The successful development of apparatus for different applications
-useful in the telegraph field was largely due to the close cooperation
-between the research-development and the manufacturing departments
-of the organization. Howard Krum had expert engineers and designers
-in his department, Kleinschmidt brought his leading engineers and
-designers from the Long Island City plant, and there was a definite
-spirit of cooperation all around.</p>
-<p>To quote again from the <i>Fortune</i> magazine story:<a class="fn" id="fr_10" href="#fn_10">[10]</a></p>
-<blockquote>
-<p>As the years up to 1925, when the Kleinschmidt-Morkrum merger took
-place, were wanderings in a profitless desert, so the years from 1925 to
-1930 found the teletype in a land of milk and honey. Mr. Morton, however,
-was inclined to think that a company which had only two or three
-major customers is not strongly placed. Furthermore (and by the spring of
-1930), at least one of those customers was actively in the market as a
-Teletype purchaser. This buyer was Colonel Sosthenes Behn, whose International
-Telephone &amp; Telegraph Co. includes Postal Telegraph at home in
-addition to many communication and manufacturing companies abroad.
-With Colonel Behn wanting to buy and Mr. Morton wanting to sell, negotiations
-rapidly proceeded to a point at which Mr. Morton, at least, thought
-the deal was almost concluded. But while Mr. Morton and the Colonel
-were discussing the prospective acquisition, into the Colonel&rsquo;s office walked
-a man who has no other place in this story except that he happened to
-interrupt at this moment. As this gentleman was introduced, he asked
-whether Mr. Morton were related to Joy or Paul Morton. When Mr.
-Morton admitted that they were his father and uncle, the man turned to
-Colonel Behn and said in jest: &ldquo;Better watch your step. That&rsquo;s a smart
-family.&rdquo; Only Colonel Behn knows whether he gave that remark any
-weight, but the point is that the negotiations suddenly collapsed, and that
-the visitor&rsquo;s remark about the smart family still lives vividly in Mr. Morton&rsquo;s
-memory.</p>
-<p>This setback was not a setback at all to such a negotiator as Mr. Morton.
-Two months later, in May, 1930, you find him walking into the office of
-Clarence G. Stoll, vice president of Western Electric, A. T. &amp; T.&rsquo;s manufacturing
-subsidiary. This time there had been no preliminaries. Mr. Stoll
-rose from his desk and said: &ldquo;Good morning. What can I do for you?&rdquo;</p>
-<p>&ldquo;Do you want to buy Teletype?&rdquo;</p>
-<div class="pb" id="Page_40">40</div>
-<p>&ldquo;Is it for sale?&rdquo;</p>
-<p>&ldquo;Yes, at a price.&rdquo;</p>
-<p>&ldquo;All right. Let&rsquo;s get down to business.&rdquo;</p>
-<p>They got down to business on the spot, and they remained at it for three
-solid days in Mr. Stoll&rsquo;s office. The agreement as reached called for
-A. T. &amp; T. to pay off the preferred stock of Teletype, 13,979 shares callable
-at 105, and to give one share of A. T. &amp; T. in exchange for each common
-share of Teletype. The A. T. &amp; T. shares were worth about $200, so the
-price came to upwards of $30,000,000&mdash;plus, of course, the $1,467,795 for
-retiring the Teletype preferred.</p>
-</blockquote>
-<p>It should be noted here that this deal to take over Teletype on a
-share-for-share basis was exclusive of foreign patent rights but did include
-patent rights in Canada and Mexico.</p>
-<p>The sale to Western Electric was closed on September 30, 1930. Mr.
-Stoll of that company was made president. Howard Krum continued
-on as vice president and was a leader in developing a number of commendable
-devices, including a system for transmitting messages in
-scrambled, untranslatable code form and receiving such scrambled code
-in perfect message form. Mr. Morton was retained as consultant. Edward
-Kleinschmidt made an arrangement to do development work for the new
-organization in a laboratory of his own, assigning all inventions to the
-Teletype Corporation (see <a href="#Page_50">page 50</a>).</p>
-<p>After Kleinschmidt left Teletype, his assistant, Albert H. Reiber,
-carried on as head of Research and Development for a short while before
-his untimely death. In the meantime, Walter J. Zenner had advanced
-and, in 1935, became Department Chief and later Vice President in
-Charge of Research and Development. Under Zenner&rsquo;s direction a number
-of new devices in the teleprinter field were developed, including
-ultra-high-speed tape-perforating and tape-controlled transmitting devices,
-as well as a high-speed stock ticker operating at 900 characters per minute
-(introduced in 1964) to replace the earlier Morkrum-Kleinschmidt ticker
-which operated at 500 characters per minute. Some 94 patents were
-issued in his name, which have contributed greatly to the growth of
-the Teletype Corporation.<a class="fn" id="fr_11" href="#fn_11">[11]</a></p>
-<p>On May 15, 1940, Howard Krum and Edward E. Kleinschmidt were
-both honored by The Franklin Institute and awarded the John Price
-Wetherill Medal, each one &ldquo;For his Part in the Development of a
-Successful Electrically Operated Duplicate Typewriting Machine Now
-Known as the Teletypewriter,&rdquo; (Quoted from the medal certificate.)</p>

-<p>Howard Krum later also received an award as Modern Pioneer from
-the National Manufacturers Association. Edward E. Kleinschmidt, on
-April 19, 1958, was awarded the honorary degree of Doctor of Engineering
-at the Polytechnic Institute of Brooklyn.</p>
-<p>To continue: After the sale of patent rights in Canada, Mexico, and
-the United States to Western Electric, there remained the European and
-other foreign patent rights still with the original Morkrum and Kleinschmidt
-investors. The International Telephone and Telegraph Company
-wanted these rights, and, after negotiations in New York, a price was
-set for their purchase through the Creed Company in London, then
-owned by IT&amp;T. Edward Kleinschmidt was sent to London in 1930
-to close the deal. Some changes to the sales contract were requested by
-Creed which kept the cables busy by Kleinschmidt in asking for approval
-from A. T. &amp; T. and Western Electric lawyers. Finally, upon all-around
-approval, the contract was signed at the previously-agreed-to price of one
-and a quarter million dollars.</p>

-<br />Teletypewriter Intercommunication Expands</h2>
-<h3 id="c6"><i>TELEX</i></h3>
-<p>As a result of the acquisition of patents of the Morkrum-Kleinschmidt
-Company by the Lorenz company, Siemens &amp; Halske, and, later, the
-Creed company in England, all of which we have discussed briefly,
-teletypewriter intercommunicating expanded rapidly. In just a short time,
-through the cooperation of these companies, it spread over all of Europe
-and was named TELEX (<i>TEL</i>eprinter <i>EX</i>change Service).</p>
-<p>Dr. Gerhard Grimsen of the Lorenz company, in a letter to Edward E.
-Kleinschmidt, dated July 11, 1962, states, in part (slightly edited):</p>
-<blockquote>
-<p>The story of printing telegraph apparatus using an equal length code in
-the Lorenz Co. commences in 1927 with the acquisition of the most important
-patents of the Morkrum-Kleinschmidt Co.</p>
-<p>Before then, the Lorenz people were busy in manufacturing Morse
-apparatus and delivering exchange tickers which used the Hughes code.
-The transmitter had a piano keyboard, the receiver was a page printer with
-a moving type wheel.... The biggest network of this kind was installed in
-the Berlin Police service (with one transmitter and about 300 receivers).
-The connections between the headquarters and the substations were built
-by using guttapercha cable lines owned by the police administration. This
-broadcasting network was erected around 1907. By 1927 the cables had
-aged, by normal corrosion, to such a degree that instead of 110-volt double
-current transmitting voltage, little by little, up to 220 volts was necessary
-for a fairly satisfying operation. Also, the maintenance of the apparatus
-became more costly.</p>
-<p>This was the situation when some communication experts of the police
-and the post administration made the first studies about the newest telegraph
-technique in the U. S. A.... They found that the start-stop, five-unit
-tape printer, the Model 14, developed and manufactured by the Morkrum-Kleinschmidt
-company, would be the best instrument to replace the old
-ones in the police service as well as in the telegraph business of the German
-post administration.</p>
-<p>Of special importance to the police service was the fact that by introducing
-this apparatus, it was not necessary to build a new network because now
-it became possible to rent normal telephone lines using single current,
-40-milliampere, 60-volt current only.</p>
-</blockquote>
-<div class="pb" id="Page_43">43</div>
-<p>Siemens and Halske engineers, in 1925, had designed a teleprinter
-using the five-unit-code, start-stop principle. This was manufactured and
-improvements added, including the new start-stop method developed by
-Morkrum-Kleinschmidt. The Creed company, which had started manufacture
-of start-stop teleprinters before 1930, having purchased several
-Morkrum printers before the consolidation of that company with the
-Kleinschmidt company, also designed a teleprinter for the new five-unit-code,
-start-stop system.</p>
-<p>In another write-up, Dr. Grimsen states that after the Siemens company
-came into the picture, a fully automatic teleprinter network was
-started in 1933 with a trial installation between Berlin and Hamburg
-for about forty private subscribers. The results were so encouraging that
-the German Reichspost continued the work, and five years later the
-TELEX system contained about 10,000 subscribers.</p>
-<p>TELEX service was introduced in Great Britain in 1932 and was
-worked over the telephone network, using a single-tone voice frequency
-carrier signal which was keyed on and off by the teleprinter transmitter.
-(From Freebody&rsquo;s <i>Telegraphy</i>.)<a class="fn" id="fr_12" href="#fn_12">[12]</a></p>
-<p>Interconnection for TELEX service was made by dialing a subscriber
-as in telephone operation. TELEX directories then, as now, gave the call
-numbers of subscribers. Types of answerback devices were designed in
-both England and Germany which finally developed into an arrangement
-whereby the calling subscriber would, after dialing a number, press a
-special key, the shifted D key&mdash;named the &ldquo;Who-Are-You?&rdquo; button&mdash;which
-would cause the transmission of a signal code automatically to
-activate the called teletypewriter mechanism into transmitting its TELEX
-number.</p>
-<p>Further apparatus, a device to punch the code in a tape and a punched-tape-controlled
-transmitter, was soon added.</p>
-<p>The Siemens company also developed and built completely automatic
-switching equipment for the TELEX system which is used by many
-telegraph administrations.</p>
-<p>Through the cooperation of the companies who were manufacturing
-teleprinters and associated equipment, the many problems that appeared
-were eventually solved to improve the apparatus and bring the TELEX
-<span class="pb" id="Page_44">44</span>
-system to eventual perfection for worldwide telegraph communications.
-(At the time of this writing, according to statistics, there are nearly
-1,000,000 TELEX subscribers throughout the world.)</p>
-<p>One of the problems faced in setting up such a worldwide system was
-that of standardizing the code and operating speed. At the time of Kleinschmidt&rsquo;s
-stay in London in 1930 to close negotiations with Creed for the
-sale of Morkrum-Kleinschmidt&rsquo;s foreign rights, he met Mr. Martin Feuerhahn
-of the German Telegraph Administration who at that time was in
-conference with Creed and representatives from the British Telegraph
-Administration as to standardizing on an alphabet and telegraph code
-for international communications. Mr. Feuerhahn argued for the adoption
-of the American Murray alphabet and code, stating that he already
-had the approval and consent of the French, Italian, and Belgian telegraph
-administrations.</p>
-<p>Mr. Feuerhahn and Kleinschmidt spent some hours together. After
-their return to their respective countries, Kleinschmidt received a letter
-from Mr. Feuerhahn referring to their talks and stating that he had been
-in correspondence with Mr. Benjamin of Western Union and Mr. Parker
-of Bell Laboratories with regard to code and other pertinent matters of
-standardization so that an International Teleprinter Exchange could be
-extended into the United States. Another letter dated October 10, 1931,
-reviewed the aforementioned standardization search.</p>
-<p>The Murray alphabet and 7&frac12;-unit code were soon adopted and are
-still in use today in TELEX.</p>
-<p>In later years, an association, the Consultative Committee on International
-Telegraph (CCIT&mdash;now the CCITT to include the telephone),
-was formed and met regularly to discuss problems and to set operating
-regulations for the TELEX apparatus in an intercommunicating system.
-The CCITT at this writing is still meeting regularly on worldwide standardization
-in both telegraph and telephone communications.</p>
-<h3 id="c7"><i>TELEX IN THE UNITED STATES AND TWX</i></h3>
-<p>In the United States, in November 1931, the Bell Telephone Companies
-announced an intercommunicating teletypewriter service, called
-TWX for short (<i>T</i>eletype<i>W</i>riter e<i>X</i>change), by which interconnections
-could be made by a switchboard operator as in telephone service. One of
-their first advertisements named it a &ldquo;Telephone Typewriter Service, a
-<span class="pb" id="Page_45">45</span>
-service that typewrites by wire, a method of inter-office communication
-that has the quickness of the telephone, the flexibility of conversation, the
-accuracy of the typewriter, the authority of the printed word, the permanency
-of print.&rdquo;<a class="fn" id="fr_13" href="#fn_13">[13]</a> Tape-punching and tape-controlled transmitting apparatus
-was provided. This service allowed subscribers to carry on a
-typewritten conversation at a charge less than the cost of a telephone call,
-whether to local or to distant areas. The maximum speed of this equipment
-was limited to sixty words per minute.</p>
-<div class="img" id="ill15">
-<img src="images/p13.jpg" alt="" width="500" height="588" />
-<p class="pcap">Telephone Typewriter Service (early TWX apparatus)<span class="btr small"><i>reproduced by permission of American telephone &amp; Telegraph Co.</i></span></p>
-</div>
-<div class="pb" id="Page_46">46</div>
-<p>There are approximately 54,000 subscribers to TWX at this writing,
-and the TWX directory gets fatter with each new issue. In 1962 all TWX
-machines were converted to direct dialing operation, making the service
-easier to use. Instead of going through &ldquo;Operator&rdquo; by manually typing
-out the call letters of the party being called, one now merely depresses
-the Originate button, listens for the dial tone, and then dials the TWX
-number of the party wanted.</p>
-<p>RCA Communications, Inc., was the first to extend international
-TELEX service to Bell System teletypewriter subscribers (1955), enabling
-them to make and receive overseas calls on their domestic TWX
-machines.<a class="fn" id="fr_14" href="#fn_14">[14]</a> As stated, the TWX machines were geared for 60-words-per-minute
-operation, whereas the TELEX system operated at 66 words per
-minute. It was therefore necessary for R.C.A. to use conversion apparatus
-to an error-detecting code for overseas radio transmission. This code was a
-seven-unit code, using three marking and four spacing elements, giving
-35 usable combinations. By using a special printer, when a faulty combination
-was received, a special error symbol was printed.</p>
-<p>Western Union, in May of 1958, introduced TELEX service between
-New York City and various Canadian points. By 1962 the service had
-been extended to 67 United States cities, and at this writing they expect
-to serve 180 United States cities with an anticipated subscriber capacity
-of many thousands.<a class="fn" id="fr_15" href="#fn_15">[15]</a></p>
-<p>In addition to domestic service between U. S. cities, subscribers can
-dial automatic teleprinter connections to Canada and Mexico. Also, they
-can obtain direct TELEX connections to other parts of the world through
-the overseas facilities of RCAC (Radio Corporation of America Communications),
-AC&amp;R (American Cable and Radio), and WUI (Western
-Union International). The operating speed of 66 words per minute and
-also the teleprinter keyboard in the U. S. TELEX network conform to
-international standards of the CCITT. This provides complete operating
-compatibility with other TELEX systems throughout the world without
-the need for speed and keyboard translators.<a class="fn" href="#fn_15">[15]</a></p>

-<h2 id="c8">CHAPTER 6
-<br />KLEINSCHMIDT LABORATORIES</h2>
-<p>As we have seen, Edward Kleinschmidt, upon resigning from Teletype
-Corporation as vice president when it was taken over by Western Electric,
-had agreed to do development work for them, working independently
-but assigning any inventions to the new Teletype Corporation.</p>
-<p>And so it was that Kleinschmidt Laboratories came into existence.
-Incorporated on March 21, 1931, under Delaware laws, for the immediate
-purpose of doing research and development work for Teletype, the
-principals of the new company were Edward E. as president, and his
-two sons, Edward F. as vice president and Bernard L. as secretary.</p>
-<p>Kleinschmidt had earlier proposed a comprehensive and completely
-automatic printing telegraph switching system in which messages are
-automatically routed from the subscriber printer through telegraph centrals
-of the addressee printer under control of address tape perforations.
-Under his development contract with Teletype he continued work on
-the system. Message storage in perforated tape was provided for at all
-central switching points, and an answerback arrangement was included
-in the system by the automatic return transmission of the addressee&rsquo;s
-number to the sender.</p>
-<p>As the research and development work for Teletype continued, the
-switching system was completed, and various other devices of more or
-less importance were developed, with patents assigned to the Teletype
-Corporation. In late 1934 the contract with Teletype expired.</p>
-<p>At that time, son Bernard was operating a printing plant in rather close
-quarters in Highland Park, Illinois. The operations of the Laboratories
-had been carried on in rented quarters at the Merchandise Mart in
-Chicago. Seeing that there would be no work for Teletype, it was decided
-to set up working quarters in Highland Park where the family lived.
-Since rented space was not available, a building was constructed on
-Lincolnwood Road in the Braeside section of Highland Park to house
-both the B. L. Kleinschmidt Printing Company and the machinery and
-<span class="pb" id="Page_51">51</span>
-other equipment of the Laboratories. The Laboratories, now inactive,
-became a personal holding company with 2300 shares to cover a book
-value of approximately $230,000.00 (Kleinschmidt having distributed
-the major portion of these shares to his children and grandchildren).</p>
-<p>Son Edward F. turned his thoughts to other fields and carried on experimental
-work in the new building in devices not connected with the
-telegraph. Son Bernard was involved in his printing business. Their
-father&rsquo;s thoughts lay dormant for a long time, but still there was the urge
-to continue with the telegraph, and a plan for operating a five-unit-code
-selecting mechanism, operating on a progressive stop principle to position
-a typewheel or to select a typebar for printing on tape or page, was worked
-out.</p>
-<p>When models of this new plan were completed and operating successfully,
-Edward E. Kleinschmidt immediately thought of Teletype Corporation
-and brought the apparatus to their attention, submitting models
-and patent applications for their evaluation. After numerous conferences
-and correspondence, however, his offer for the sale of patent rights and
-models was rejected. Discouraged, he left the completed models at the
-Highland Park lab and moved to Florida.</p>
-<p>During the second world war, son Bernard abandoned his printing
-establishment and started a tool and die shop, using the machinery and
-facilities of the Laboratories as well as space occupied by his printing
-shop. The B. L. Kleinschmidt Company was kept busy building tools,
-dies, and special devices for the war effort.</p>
-<p>Through Bernard&rsquo;s associations he learned that the United States
-Signal Corps needed a light-weight, transportable teleprinter for tactical
-field use, and he asked his father if he could show the progressive stop
-printer to the Signal Corps at their Chicago headquarters. His father, in
-Miami at that time, gave his approval. Two days later, the telephone rang
-in Miami and it was Bernard saying, &ldquo;Dad, they are interested and want
-you to bring the printer model to Army Headquarters in Washington.&rdquo;
-Nothing could have pleased his father more!</p>
-<p>In February of 1944, Edward E. Kleinschmidt demonstrated a working
-model of his teleprinter in Washington at the office of the Chief Signal
-Officer. Officials of the Signal Corps were greatly interested in the unit,
-not only because of its extreme lightness and small bulk, but because
-of the representations that the basic design features of this tape printer,
-<span class="pb" id="Page_52">52</span>
-exclusive of the printing mechanism, could be incorporated in a page-type
-printer which could be constructed with a total weight of approximately
-thirty pounds. The machine was subsequently informally tested
-at the Signal Corps Engineering Laboratories and found to have excellent
-margins when working without an intermediate relay on very low line
-current, a highly desirable feature in a piece of tactical teletypewriter
-equipment.</p>
-<p>The exhibit at Headquarters was successful, and after operative tests
-at the Signal Corps&rsquo; Coles Signal Laboratories in Red Bank, New Jersey,
-where approval for further studies was given, the Kleinschmidt organization
-was asked to prepare plans toward a tactical light-weight printer
-for field use.</p>
-<p>It should be pointed out that teletypewriters at that time were heavy,
-cumbersome, and intended for use only at telegraph offices or at other
-plant or office fixed installations.</p>
-<p>The plans for a light-weight page printer were submitted to the Signal
-Corps as requested and were well received by their engineers. These
-engineers then wrote up specifications detailing their requirements for a
-rugged, light-weight portable set for hand-carrying through jungles and
-swamps, and operable under severe climatic conditions; the specifications
-were submitted to the Teletype Corporation, the Western Union Telegraph
-Company, and to the Kleinschmidt organization. Western Union
-did not take on the development job, but Teletype and Kleinschmidt
-accepted. A contract for the development of a teletypewriter according
-to Signal Corps specifications was closed with both companies in 1945.</p>
-<p>The Kleinschmidt Laboratories were not in active operation at this
-time, so the first development contract was closed with the B. L. Kleinschmidt
-Company which was fully equipped to carry on the work. Expert
-tool and model makers were in his employ, some of whom turned out
-to do well at the drawing board and were of great help in working out
-mechanical functions. As a matter of fact, five or six of Bernard&rsquo;s employees
-are still with the Kleinschmidt Division of SCM Corporation
-at this writing, some having attained supervisory positions.</p>
-<p>Edward F. joined his father in further engineering and development
-work, and models of a typebar page printer and a typewheel page printer
-to operate at 60 words per minute were built. Upon evaluation by the
-Signal Corps and Army engineers, a printer with a higher operating
-<span class="pb" id="Page_53">53</span>
-speed, up to 100 words per minute, was demanded. This new requirement
-meant a complete redesign of apparatus, but it was successfully
-carried through and experimental models were submitted by both companies.
-Thereupon both Kleinschmidt and Teletype were asked to build
-ten printers for field tests. This was done, and after extensive field testing,
-the Kleinschmidt-designed, keyboard-operated, 100-words-per-minute
-typebar page printer was accepted, and, by order of the then Secretary of
-War, it was made the standard for the Military, effective on January 1,
-1949. (This printer was later to be known as the TT-4 tactical page
-printer, the principal component of Teletypewriter Set AN/PGC-1.)
-(See <a href="#fig13">fig. 13</a>.)</p>
-<p>An announcement from the Department of the Army, in a document
-released for publication on February 13, 1949,<a class="fn" id="fr_16" href="#fn_16">[16]</a> read as follows:</p>
-<blockquote>
-<p><span class="center"><i>Portable Teletypewriter Developed by Signal Corps</i></span></p>
-<p>Portable teletypewriter equipment so light that a parachutist can carry
-it on a jump from an airplane has been developed and adopted by the Army,
-promising a major advancement in military communications, the Signal
-Corps announced today.</p>
-<p>Weighing but 45 pounds, compared with current field equipment that
-weighs 225 pounds, the new portable teletypewriter is but one-fourth the
-size of the old, has 300 fewer parts, is considerably stronger and consequently
-requires far less maintenance. The new equipment is capable of
-transmitting and receiving messages 66 per cent faster than existing types
-and will operate on both wire and radio circuits. It is waterproof and should
-it be used in amphibious operations, could be floated onto a beach.</p>
-<p>The development is the fruition of a 20-year-old project that did not get
-under way in earnest, however, until World War II was nearly over.</p>
-<p>Because of its light weight, the new teletypewriter can be used much
-closer to the front lines than has been the case. During World War II,
-teletyped messages could go only as far forward as a division headquarters.
-How much farther forward the new equipment can be used, will be determined
-in forthcoming field tests.</p>
-<p>The portable teletypewriter was developed by the Signal Corps Engineering
-Laboratories at Fort Monmouth, New Jersey, through a research and
-development contract with Kleinschmidt Laboratories, Incorporated, of
-Highland Park, Illinois.</p>
-<p>There are three components to a complete field unit: the teletypewriter
-itself, weighing 45 pounds; a power unit, and a case of accessories. The
-<span class="pb" id="Page_54">54</span>
-three together weigh 116 pounds. All units are waterproof, both to permit
-flotation in amphibious activities and to provide complete protection from
-weather. One man can carry the teletypewriter itself, while two men can
-carry all three units.</p>
-<p>The field teletypewriter in current use weighs 225 pounds and&mdash;if a
-vehicle is not available&mdash;requires four men to carry it. With power unit and
-accessories, present field equipment totals more than 400 pounds and
-requires seven men to carry it.</p>
-</blockquote>
-<p>While development work for the Signal Corps was progressing, Bernard
-kept busy managing general operations and Edward F. took hold
-in the general design and devised important features that were patented
-in his name.</p>
-<p>Bernard died in March, 1948. However, development work went
-along with the B. L. Kleinschmidt facilities until 1949, when a production
-order for 2,000 teleprinters, conforming to the now approved Kleinschmidt
-design, was to be placed. Now that Bernard was no longer there to take
-over business details, and as a certain amount of basic capital was needed
-to operate a production establishment, arrangements were made to transfer
-Bernard&rsquo;s equipment to Kleinschmidt Laboratories which thereafter
-closed a contract to manufacture the required quantity of teleprinters now
-designated as the TT-4 telegraph typewriter.</p>
-<p>Kleinschmidt senior, now seventy-four, was not eager to take over the
-management of production activities, and while manufacturers in the
-office equipment and radio field were ready and anxious to take on the
-manufacture of these new teleprinters, he sought to keep the future of
-this new development with the Kleinschmidt Laboratories&mdash;now owned
-by all members of his family. His son-in-law, Emerson E. (Bud) Mead,
-was operating a manufacturing plant, producing electrical control devices
-quite successfully, so, &ldquo;Why not ask Bud, then Secretary of Kleinschmidt
-Laboratories, to take over? He could no doubt sell the Mead company at
-a profit.&rdquo; Bud did find a buyer for his company and he was then made
-vice president of Kleinschmidt Laboratories; later, when Edward E. Kleinschmidt
-turned over full management to him, Mead became executive
-vice president.</p>
-<p>The immediate problem at the Laboratories was to find manufacturing
-space. The first thought was to rent, but then there would be no room
-to expand should larger orders follow, and this could be expected since
-Kleinschmidt teleprinter apparatus was now made standard equipment
-for all U.S. Armed Services. Upon further investigation, Bud Mead
-found a plot in Deerfield, Illinois, facing County Line Road, consisting
-of thirteen acres, which could be purchased at a reasonable price. This
-area would give plenty of building room and space for parking cars.
-Kleinschmidt Laboratories&rsquo; first building, 200 &times; 150 feet, was soon erected.</p>

-</div>
-<div class="pb" id="Page_56">56</div>
-<p>Preliminary work toward manufacturing, drawings, ordering of production
-machinery, special tools, standard parts, and other items was carried
-on at the Braeside laboratory.</p>
-<p>The efforts of all of the people of the Kleinschmidt organization,
-working with great enthusiasm and wonderful cooperation, sometimes
-around the clock, were rewarded when on April 17, 1950, preproduction
-samples of light-weight teletypewriter sets were delivered on schedule to
-the Signal Corps in Fort Monmouth for approval and acceptance. Immediately
-upon receipt of their approval, production began on the contract
-awarded in June of 1949.</p>
-<p>Kleinschmidt Laboratories subsequently received contracts and built
-thousands of their teleprinters, including the filling of orders for the
-AN/FGC-20 fixed station teleprinters (see <a href="#fig14">fig. 14</a>).</p>
-<p>Later, the Laboratories, together with the Automatic Electric Company,
-then of Chicago, now of Northlake, Ill., designed and built switching
-apparatus and set up high-speed, 100-words-per-minute, automatic teleprinter
-switching centers for the Military. These systems had trunk
-switching controls located at key distributing points in the United States
-and abroad, interconnected by microwave circuitry.</p>
-<p>As further orders for teleprinters and associated equipment came along,
-manufacturing facilities were expanded into more building area; additions
-to the first unit brought that building to 200 &times; 500 feet. Another building,
-250 &times; 350 feet, of special design to house belt-line apparatus assembly
-and parts storage, also testing, inspection, and shipping, was erected in
-1958.</p>
-<p>In August, 1956, Kleinschmidt Laboratories merged with Smith-Corona
-Inc., on an exchange-of-shares basis, which eventually gave
-Kleinschmidt Laboratories&rsquo; shareholders 60 shares of Smith-Corona (later
-Smith-Corona Marchant Inc., and then SCM Corporation) stock for one
-share of Kleinschmidt Laboratories&rsquo;. Bud Mead was elected a director
-and a member of the executive committee. Later, he became vice president
-<span class="pb" id="Page_57">57</span>
-of operations. When Smith-Corona merged with Marchant Calculators,
-Inc. (June, 1958), he was made executive vice president; then,
-in October of 1960, he was named president of Smith-Corona Marchant
-Inc. (now known as SCM Corporation).</p>
-<p>Kleinschmidt, as a Division of SCM Corporation, continues to supply
-the Military and also commercial users with teleprinter equipment. The
-conclusion of this chapter tells briefly the direction the Kleinschmidt
-Division is going in the printed communications field.</p>
-<p>Before the Kleinschmidt 100-words-per-minute teleprinter was put into
-service on intercommunicating circuits, the operating speed on standard
-circuits had been limited to 60 words per minute. Noting this important
-change in operating speed, other manufacturers had to redesign their
-teleprinter equipment to meet the new 100-words-per-minute speed.</p>
-<p>Teletype Corporation came up with a new design, the No. 28, in which
-all the type pallets are moveably mounted in a rectangular box that is positioned
-to move a selected type pallet into printing position by a system
-of levers operated in aggregate motions under control of the code selecting
-mechanisms (<a href="#fig15">fig. 15</a>). When so positioned, a print hammer strikes the
-type pallet to print the character.</p>
-<p>Creed, in England, later brought out a new design, their No. 75, using
-a segmented typewheel having four rows of type faces. The typewheel
-is set in the selected printing position by a lever and linkage system
-operating in aggregate motion under control of the code selecting mechanism.
-To print the selected character, the typewheel is struck against
-the printing paper (<a href="#fig16">fig. 16</a>).</p>
-<p>Siemens and Halske, in Germany, produced their No. 100, a redesign
-of the No. 15 Teletype, using lighter and faster moving parts for operation
-at 100 words per minute. Among other improved features were a
-type bar shift to replace the platen shift for printing letters or figures,
-and a two-color ribbon which is automatically shifted to print in red or
-black to distinguish between sent and received messages&mdash;a feature of
-convenience in TELEX communication. The Siemens No. 100 was
-designed especially for the TELEX system, operating at 66 words per
-minute, where it is used extensively (<a href="#fig17">fig. 17</a>).</p>

-<p>The Kleinschmidt printer, designed to operate at 100 to 150 words a
-minute, employs a new method for operating a typebar printing mechanism,
-comprising a type basket movable across the printed page and
-carrying the required set of type bars. Each type bar has a connected
-push rod extending to the rear of the type basket and is made operative
-to cause printing when a rotating finger, selectively positioned by a coded
-stop cage, is struck against the push rod. To meet the requirements of the
-Military for a teleprinter operable in any angular position, the letter
-spacing and carriage return with deceleration to the stop position is under
-positive control of the motor drive.</p>

-<p>In 1948, scientists at Bell Telephone Laboratories, engaged in semiconductor
-research, announced the birth of their famous brainchild, the
-<span class="pb" id="Page_61">61</span>
-transistor. Now the little transistor and his friends, the diode and advanced
-techniques in electromagnetic inductive devices, have gradually
-taken over in the communications field, permitting startling speed
-increases and changes in equipment design.</p>
-<p>In the 100-words-per-minute teletypewriters, the permutation code
-equivalent of the character to be transmitted or received was at some
-point &ldquo;set up&rdquo; mechanically by positioning levers or vanes. The inertial
-properties of these mechanical parts placed low-level limitations on the
-operating set-up speed. By using the binary code and electronic switching
-circuits, the set-up time has been reduced from milliseconds to microseconds,
-making higher speeds more easily obtainable. Also, electronic
-approaches to printing on page or tape have contributed to the speed-up
-of telegraph receiving devices. Now, both tape and page devices are
-available at operating speeds up to 10,000 words per minute.</p>
-<p>Thanks to the Bell System, also, is the development of Data-Phone
-service, started in 1958. Data-Phone makes use of all the telephone
-switching devices and repeating apparatus so that any type of communicating
-system using frequencies within the voice range may be used.
-For such systems the telephone company will install equipment to separate
-the different types of electrical transmission to prevent interference. Because
-Data-Phone enables not only the sound of the human voice to be
-sent over a telephone circuit, but information from a teletypewriter or
-business machine as well, this new use for the telephone system has
-expanded its service to many types of business communications. At this
-writing, the Bell System advertises, &ldquo;Data-Phone &lsquo;talks&rsquo; 16 times faster
-than people talk. It can send punched card or taped data anywhere&mdash;at
-speeds up to 2500 words per minute.&rdquo;</p>
-<p>While these advances have been taking place, the transistor and its
-companions have made a similar impact in the field of data processing.
-The rapid evolution of computers and other high-speed switching devices
-has generated a need for higher speed equipment to supply input and
-output requirements. The changeover to electronics has realized minification,
-lighter weight, reduction of mechanical parts with a corresponding
-reduction in maintenance, quieter operation, and greater adaptability
-to code and language conversion.</p>

-<p>At the Kleinschmidt Division where Mr. Emilio J. Cadamagnani,
-Executive Vice President, is in charge, their engineering department,
-under the supervision of Mr. Robert L. Kearney, is keeping up with the
-change from electromechanically- to electronically-controlled devices.
-Their new Model 311 Electronic Data Printer shown here is an example.
-Operating at speeds from 60 to 400 words per minute and capable of
-receiving 5-, 6-, 7-, or 8-level code information in either serial or parallel
-form, it is designed for use in high-speed communications or data
-processing systems.</p>
-<p>Also illustrated is still another new Kleinschmidt device, the Model
-321 Automatic Data Set, which includes not only a page printer with
-keyboard but a tape perforator and a tape reader, all compactly mounted
-in a console.</p>
-<p>Both the Model 311 and Model 321 are compatible with existing
-data modems, conventional printing telegraph equipment, electronic
-computers, and data processing equipment. This compatibility permits
-their use in on-line or off-line communications and data-handling applications.</p>
-<p>More exciting devices may be anticipated in the rapidly moving field
-of printed communications.</p>

-Section 2. Information about the Mission of Project Gutenberg-tm
-
-Project Gutenberg-tm is synonymous with the free distribution of
-electronic works in formats readable by the widest variety of
-computers including obsolete, old, middle-aged and new computers. It
-exists because of the efforts of hundreds of volunteers and donations
-from people in all walks of life.
-
-Volunteers and financial support to provide volunteers with the
-assistance they need are critical to reaching Project Gutenberg-tm's
-goals and ensuring that the Project Gutenberg-tm collection will
-remain freely available for generations to come. In 2001, the Project
-Gutenberg Literary Archive Foundation was created to provide a secure
-and permanent future for Project Gutenberg-tm and future
-generations. To learn more about the Project Gutenberg Literary
-Archive Foundation and how your efforts and donations can help, see
-Sections 3 and 4 and the Foundation information page at
-www.gutenberg.org
-
-
-
-Section 3. Information about the Project Gutenberg Literary Archive Foundation

-
-Section 4. Information about Donations to the Project Gutenberg
-Literary Archive Foundation
-
-Project Gutenberg-tm depends upon and cannot survive without wide
-spread public support and donations to carry out its mission of
-increasing the number of public domain and licensed works that can be
-freely distributed in machine readable form accessible by the widest
-array of equipment including outdated equipment. Many small donations
-($1 to $5,000) are particularly important to maintaining tax exempt
-status with the IRS.
-
-The Foundation is committed to complying with the laws regulating
-charities and charitable donations in all 50 states of the United
-States. Compliance requirements are not uniform and it takes a
-considerable effort, much paperwork and many fees to meet and keep up
-with these requirements. We do not solicit donations in locations
-where we have not received written confirmation of compliance. To SEND
-DONATIONS or determine the status of compliance for any particular
-state visit www.gutenberg.org/donate
-
-While we cannot and do not solicit contributions from states where we
-have not met the solicitation requirements, we know of no prohibition
-against accepting unsolicited donations from donors in such states who
-approach us with offers to donate.
-
-International donations are gratefully accepted, but we cannot make
-any statements concerning tax treatment of donations received from
-outside the United States. U.S. laws alone swamp our small staff.
-
-Please check the Project Gutenberg Web pages for current donation
-methods and addresses. Donations are accepted in a number of other
-ways including checks, online payments and credit card donations. To
-donate, please visit: www.gutenberg.org/donate
-
-Section 5. General Information About Project Gutenberg-tm electronic works.
-
-Professor Michael S. Hart was the originator of the Project
-Gutenberg-tm concept of a library of electronic works that could be
-freely shared with anyone. For forty years, he produced and
-distributed Project Gutenberg-tm eBooks with only a loose network of
-volunteer support.
-
-Project Gutenberg-tm eBooks are often created from several printed
-editions, all of which are confirmed as not protected by copyright in
-the U.S. unless a copyright notice is included. Thus, we do not
-necessarily keep eBooks in compliance with any particular paper
-edition.
-
-Most people start at our Web site which has the main PG search
-facility: www.gutenberg.org
-
-This Web site includes information about Project Gutenberg-tm,
-including how to make donations to the Project Gutenberg Literary
-Archive Foundation, how to help produce our new eBooks, and how to
-subscribe to our email newsletter to hear about new eBooks.
