S. A. - - - - - Four Principal Activities - of the - American Bureau of Engineering, Inc. - - -The phenomenal growth of this Institution is due to the fact that it -has, from the start, anticipated the needs for authoritative information -and adequate shop equipment to take care of the ELECTRICAL side of the -automotive and allied industries. - -It has four active divisions: - - 1. A Bureau of Electrical Engineering, consulted by - automobile manufacturers, dealers and by technical schools - and colleges throughout the world. - - 2. A Publishing House, employing the highest - authorities to compile text books and Ready Reference - Manuals relating to the electrical equipment of - Automobiles, Trucks, Tractors, and Farm Lighting Plants. - - 3. A Manufacturing and Sales Organization for - supplying up-to-date shop equipment to the Battery and - Electrical Service Stations. - - 4. An Electrical School, operating this branch under - the name of “AMBU ENGINEERING INSTITUTE.” This school is - conducted so that a student can attend classes in Chicago, - or complete instruction in Automotive Electricity can be - obtained in the Home Study Course. - - =American Bureau of Engineering, Inc. - General Offices - AMBU BUILDING - 2632 Prairie Avenue - CHICAGO, ILLINOIS= - - - - - Mr. Battery Repairman - - -Before reading the following pages, Mr. Batteryman, just stop a few -minutes and take a good look around your shop. You know your business, -certainly or you would not have a shop, but are you operating in a way -to make the greatest profit? - -When you stop to think it over, are not some of your methods rather -crude? Haven't you often thought, when you were doing some disagreeable -job, that there ought to be a better and quicker way? Haven't you often -wished that you knew how to turn that rapid accumulation of “junk” parts -into real money? - -The American Bureau of Engineering is not trying to tell you how to run -your business, but we are trying to help you realize a greater profit by -showing you some “better” methods. - -Lead moulding is but one of many ways that spare time and material, -usually junked, can be turned into profit. - -Every piece of equipment we mention has been carefully developed in our -own shop, every method recommended is one which we have found, by actual -experience to be best for the purpose described. - -A strict observance of the instructions will save you all the -experimenting we have done and save you many disappointments. If for any -reason our instructions do not produce the results you think they -should, remember it is a pleasure for our Engineers to help you solve -your personal difficulties. - - AMERICAN BUREAU OF ENGINEERING - -[Illustration: C. J. Buckwalter - -President.] - - - - - Copyright 1922 - American Bureau of Engineering, Inc. - Chicago, Ill. - - - - - Profits From Scrap - - -In his every day work, the storage battery service man must deal chiefly -with three materials, wood, rubber and lead. - -The wooden parts, such as boxes and separators are pretty well -standardized, can be purchased at reasonable prices and are used solely -for replacements. It would not pay the battery man to equip his shop to -manufacture any of these items. - -[Illustration: Figure 1] - -The same is true of the rubber parts, the jars and top covers. A dozen -different sizes in stock will take care of nearly all the various makes -and models of batteries which come in for repair. - -With the lead parts, however, the conditions are entirely different. All -the active and wearing parts are made of lead, or its compounds, and -practically every battery that needs repair, needs some of them -replaced. Then again there is a much greater variety in the design of -these parts and the up-to-date shop, in order to give real service, must -carry a large assorted stock of end connectors, connector straps, plate -straps and posts. - -In speaking of lead parts, however, the plates are to be considered on -the same basis as the rubber parts or wooden boxes, because it would not -pay the ordinary battery shop to try and cast grids, mix paste and -manufacture plates. It is much more satisfactory to purchase plates made -by a responsible manufacturer who has the facilities and capital to -properly develop his formulae and processes. - -Every battery that has to be opened must have the top connectors drilled -off as in Fig. 1, which naturally makes a lot of lead chips. These -drillings have to be cleaned off before proceeding with the repair and -can, with no loss of time, all be collected, as in Fig. 2, and saved. -Then the old sulphated end connectors and parts from “junked” batteries -accumulate very fast. - -[Illustration: Figure 2] - -This then is the situation—The battery service station is constantly in -need of new lead parts. Should they be obtained from a manufacturer at a -price that includes material, labor and the manufacturer's -profit—OR—should equipment be purchased that will permit of moulding -these same parts from the accumulated scrap lead at a cost of nothing -but the time employed in pouring, with no cost for material and no -“Profits” added? - -No matter how cheap you think you are buying your lead parts, just -compare the market price per pound on lead with the weight of a few of -your “cheapest” ones. - -It is now common practice to melt some of this accumulation of scrap -lead and pour it into sticks or bars for use in lead burning on repair -work. A great amount, especially old groups, is generally sold at a low -price in order to get it out of the way. The one important fact, and one -generally overlooked, is, that the battery man who melts lead and moulds -it into sticks for lead burning, certainly is able to melt the same -metal and mould it into the lead parts he requires, provided, of course, -that he has the proper moulds. - -Many a wide awake man has whittled a wooden mould for some part that he -wanted in a hurry and couldn't wait for the manufacturer to deliver. -Naturally this condition, really an effort to render service to the -customer, created a demand for moulds of a permanent character. - -In an effort to supply this demand, the moulds that have been produced -were all made for some individual part, were light in weight and easily -became overheated, making them hard to handle and often burning the -workman's hands. - -[Illustration: Figure 3] - -From a business standpoint, it would certainly be mighty profitable for -a battery shop to be able at a moment's notice, to convert junk lead -into new salable parts. In addition to the large profit from the sale of -these new parts, another good feature, is that, instead of tieing up a -lot of capital in stock, the new parts can be made as needed, without a -cent of investment. - -From a service standpoint, it is a cheaper and faster process to cast a -new top connector than to spend a lot of valuable time, whittling an old -one so that it can be used again. - -How much time have you or your men wasted cleaning up an old terminal as -in Fig. 3, so that you could burn it on again? - -All new connectors and terminals put on a rebuilt or reinsulated job -make the customer feel that he is getting a real repair. He sees a new -finished job. - -From an electrical standpoint, the new parts mean better work, because -better burning can be done, certainly a new connection will allow the -battery to deliver more current than an old partly sulphated one could -ever do. - - - CAN YOU MAKE GOOD LEAD CASTINGS? - -The question that naturally comes up is, can the ordinary battery man -make good lead castings? We will answer “Yes,” very emphatically. There -is nothing mysterious about the work and all the talk of alloys, -compounds and formulae does not mean a great deal. - -Pure lead is not hard or rigid enough to make good battery parts, -therefore, it is necessary to add some other metal that will provide the -strength, not be affected by the acid and not increase the resistance -electrically. Antimony has all the necessary qualities, and is, -therefore, commonly used by mixing it with the pure lead. - -[Illustration: Figure 4] - -The various manufacturers recommend from 2 to 12 percent antimony, as -the proper combination, but in buying new pig lead for castings, a 4 -percent antimony compound is very satisfactory. - -In using old battery lead, however, due to chemical action the -proportion of antimony is apt to be too high to produce perfect -castings. This usually shows up by cracks or shrinkage, as in Figure 4. -To overcome this trouble, pure lead is added, until a perfect casting is -made. Pure lead can be purchased (in the form of bars, lead pipe, or -sheet lead) from a manufacturer such as the National Lead Company—your -accessory jobber, the local plumber, or the junk dealer. When buying -from a junk dealer, however, care =must= be taken that there is no -solder or tin present. - - - PREPARATION OF THE LEAD - -In order to pour the lead some means of melting and a proper container -must be provided. - -As pure lead melts at about 620°F., and antimony at 785°F., an ordinary -gas flame will furnish sufficient heat. For the small shop, without an -artificial gas supply, a plumber's furnace which can be secured from -Hardware Jobber or Plumber Jobber will work satisfactorily. See page 19 -for gas melting pots. - -An ordinary cast iron solder pot will be found the most suitable -container. It should be about 8 inches in diameter. - -It is advisable to obtain as large a pot as above, because for steady -pouring a sufficient supply of melted metal should always be available. -Then too, the constant addition of scrap or pig lead in a small pot will -often change the proportion of antimony so that the castings crack and -have to be melted over again. - -Wash the pot thoroughly with gasoline or kerosene to remove all traces -of oil. Then after it has been carefully dried, put it over the flame -and heat it gradually. Do this before putting in any lead. - -The only other equipment necessary to handle the melted lead is a ladle. -For this purpose a malleable iron melting ladle five inches in diameter -should be purchased. It can be used for stirring, skimming and pouring, -and the type with a spout, illustrated in Fig. 5 will be found most -suitable. The ladle should be cleaned and treated exactly like the -melting pot. - -[Illustration: Figure 5] - -The scrap or pig lead can now be put in the pot and melted. It is a time -saving plan to pick out carefully all the pieces of wood, rubber and -sealing compound from the scrap lead before it is put in the pot. Old -plates are not worth while melting, but a lot of good lead can be -salvaged by sawing the strap and post off old groups. Above all things -make sure that no wet parts or moisture of any kind ever gets into the -lead pot. - - - CLEANING THE LEAD - -As the lead melts most of the dross or dirt will come to the top and -float. When all the pieces are melted stir the lead with the ladle and -then skim off all the dirt. - -To help the cleaning process a piece of paraffin can be dropped into the -pot. After it has burned, the dross is more easily skimmed off. - -Another method of cleaning is to add to every ten pounds of metal, one -teaspoonful of equal parts of powdered rosin, borax and flour of -sulphur. Stir this compound in a little and when the lead is at the -proper temperature there will be a flare, flash or a little burning. A -sort of tinfoil popcorn effect will be noticed floating on top of the -metal. Continue stirring until this melts down and then skim off the -soft particles. - -An easy way to test the temperature of the melted lead is to insert the -end of a pine stick for a moment. When the wood blackens or burns, the -lead is hot enough to pour. - -Whenever the lead is in melted form and exposed to the air, as in the -iron pot, there will be a slight oxidation take place which appears as a -yellowish-red scum. Do not confuse this with the dross and dirt which is -to be skimmed off, but if the scum gets thick, then skim it off before -pouring any of the metal. - - - PREPARING THE MOULD - -One of the greatest difficulties in making lead castings has been to get -the metal to completely fill the mould. There are several reasons for -this, but they can easily be overcome. - -If the mould, which is generally made of iron, is very cold, it will -chill the melted lead and cause it to become solid before it has reached -all parts. - -The surface of a cast iron mould is very porous, and the melted lead, -partially entering the pores of the iron, is held back long enough to -chill and set. - -To remedy these faults, it is sometimes advisable to heat the mould in -order to get perfectly shaped castings. - -To close the pores of the iron moulds they are sometimes “smoked” with a -flame like that of “Prest-O-Lite” gas or else dusted with graphite. - -[Illustration: Figure 6] - -The AMBU mould compound has been developed to eliminate the necessity -for heating or smoking the mould—it remedies all the pouring troubles -and in addition, has chemical ingredients that aid in preventing the -mould from rusting. AMBU mould compound is placed in a little sack, -contained in each can, and the surface of the mould dusted with the -sack, as shown in Figure 6. - -The compound completely fills the pores of the iron, produces perfect -castings with a cold mould and prevents the finished part from sticking. -It does not wear off as quickly as the “smoke,” and dusting from time to -time, while castings are being made will produce a high polish on the -mould surface which will result in even better castings. - -The mould in Figure 6 is the new AMBU Washburn combination link mould, -which casts 15 parts, being reversible much like the ordinary “waffle -iron.” The side being “dusted” casts four top connectors of different -lengths. - - - POURING THE LEAD - -Placing the mould as in Figure 7, the lead is poured in the four -openings until the metal projects slightly above the top. - -To pour properly first skim the dross as previously explained, then with -the ladle, push the film of oxide away and dip into the clean pure lead. -Pour steadily until the mould is filled and the metal projects slightly -above the top. As it cools there will be quite a little contraction -which takes up most of the excess lead. - -[Illustration: Figure 7] - -=Never=, under any conditions, stop pouring with a mould partially -filled. Always be sure there is enough melted lead in the ladle to -completely fill the mould, before starting to pour. - -The mould can now be easily opened by pulling on the handles especially -if it has been properly dusted with the Ambu Mould Compound. - -After the mould is opened, Figure 8, the castings are easily removed, -without damage to either the mould or the casting proper. The workman -does not, at any time, handle the hot parts of the mould or the hot -castings. - -[Illustration: Figure 8] - -The mould weighs 25 pounds, and is large enough to absorb sufficient -heat to allow continuous pouring without becoming overheated. It is -solid enough to be used without the need of a vise. - - - IMPORTANT INSTRUCTIONS - -In all lead moulding, there are several important points to remember: - -1. Never put anything in the lead pot that is not perfectly dry. A few -drops of water in a pot of melted lead will cause an explosion and the -hot lead will be thrown all over the shop burning and perhaps blinding -the workman. - -2. Have all moulds clean and dry. - -3. Keep the melted lead in the lead pot clean at all times. - -4. Always completely fill each mould at one pouring. - -5. Dust moulds well with Ambu mould compound before pouring. - -6. When castings “shrink” and crack, add pure lead to that in the pot -until the trouble is remedied. - -7. Be sure melted lead is of proper temperature, by pine stick test, -before starting to pour. - -8. Remove castings as soon as they set, to prevent the mould from -becoming too hot. - -9. A perfect casting, that breaks when taken out of the mould, has -probably not been allowed sufficient time to “set” or cool properly. - -10. Never use a hammer on the surface of the mould. If a casting should -stick, pry it out. - - - AMBU COMBINATION LINK MOULD - -Using both sides, this mould casts five of the most used connectors for -all batteries, using Standard Jars, 7-9-11-13-15 Plate four end -connectors (two Dodge Tapers and two Standard Tapers, Negative and -Positive), one end connector, ⅜-inch wire leed used on 12-volt Maxwell -and other cars using wire leed. One small wire leed to connect with end -post on storage battery requiring direct connection. Post support rings, -which fit the two sizes standard rubber covers; also fit perfectly all -posts cast with our post mould. Two handy washers that sometimes are -badly needed when installing a new or rent battery. - -[Illustration: Figure 8A[1]] - -Extra taper plugs can be furnished, also extra bushings for different -size cable. Standard equipment as furnished includes four taper plugs, -one large and one small cable bushing. - -The top connectors most frequently replaced are the taper end -connections and end connections with wire cable leads. For battery men -desiring these parts, but not the large combination link mould, the -AMBU-Washburn terminal mould, Figure 9, has been designed. It has the -same general good features of the larger mould, and casts four end -connectors, one wire cable leed and two washers. - -[Illustration: Figure 9[1]] - - - AMBU POST STRAP MOULD - -Perhaps the most expensive item of a stock in a battery station, is the -supply of positive and negative groups. While two or three sizes of -plates will fit practically every battery, each size battery requires a -different size of group. - -[Illustration: Figure 10[1]] - -The AMBU-Washburn Post Strap Mould has been developed in order that a -comparatively small stock of plates can be instantly available for -making any size of group. You will notice in Figure 10, that the same -features, as those of the link mould of Figure 8 are used, namely; a -large substantial base, no need of handling hot parts and the easy -removal of castings. All parts of the moulds are carefully machined to -produce perfect castings and the patented movable tooth rack will make -odd or even numbers of teeth on the post strap. The teeth are correctly -spaced for all standard batteries, or by reversing the tooth rack, blank -posts can be cast. - -Two bushings, bored and reamed for standard size posts, are furnished, -but special bushings are available making it possible to cast any type -of post strap. - - - AMBU PRODUCTION POST STRAP MOULD - -For the large shop or manufacturer, the AMBU-Washburn Post Strap Mould, -is made with the special indexing feature of Figure 11. This is easily -adjustable and will cast straps of both odd and even numbers of teeth -for 7 to 19 plate groups. Otherwise its construction and appearance is -the same as Figure 10. - -Both of these moulds are made for real use and will turn out three -perfect castings per minute. This unusual speed can be maintained -because the castings are easily removed. In Figure 10, the upper part of -the mould is resting on a part of the handle made for that purpose and a -slight blow on a hardwood stick, on the top of the post, will drop the -casting instantly. - -[Illustration: Figure 11[1]] - - - AMBU CELL CONNECTOR MOULD - -The AMBU-Washburn Cell Connector Mould is a combination mould which will -cast practically all of the cell connectors used on standard storage -batteries, 7-11-13 and 15 plate, such as the Exide, Willard, U. S. L., -Vesta, Philadelphia and other nationally known batteries. Its design is -similar to our Link Combination Mould. - -Made of fine gray iron, carefully machined. Castings are easily removed, -and it is heavy enough so that it will not overheat where speed is -required. - -[Illustration: Figure 12] - -After re-insulating or repairing, the job looks more complete and -satisfactory to your customer if the battery is furnished with a new set -of connectors. Use your scrap lead and make new connectors for each job. -It pays. - - - AMBU SCREW MOULD - -The lead capped screws of the taper type terminal are another of the -frequently replaced parts. Although the round knurled head type is no -longer installed, a great many men still use pliers on the square head -terminal screws with the result that the soft square lead head is -damaged to such an extent that a tight connection cannot be made. - -The AMBU-Washburn Screw Mould, Figure 13, will cast standard square -edged heads on four screws in one operation, two ^5⁄_{16}-inch and two -⅜-inch. It has screw adjustments in the base, making it adaptable to any -length screw. - -[Illustration: Figure 13[1]] - -As the finished screws are removable from the top, the position of the -mould is not changed while in use and castings can be made at the rate -of 12 screws a minute. - - - AMBU LEAD STICK MOULD - -In order to properly burn in and assemble the new lead parts, it is -necessary that they be fused and new lead added, and this requires that -a supply of lead sticks be available. These are usually made by melting -the smaller particles of scrap and junk lead which is cast in convenient -size. - -The Ambu Mould, Figure 14, is especially designed for this purpose. It -is made of heavy sheet iron, die stamped into grooves and mounted on a -wooden base with a strong wooden handle at one end. A heavy pad of -asbestos is placed under the iron to protect the wood. - -[Illustration: Figure 14[1]] - -This construction allows the lead to completely fill the grooves before -cooling, but prevents the mould from becoming exceedingly hot with -constant pouring. A pair of these moulds will keep one workman busy, as -he pours one, the other is cooling. This eliminates all waiting and -waste of time. - -The sticks made are 15 inches long, ^5⁄_{16} inch thick, ⅜ inch wide at -the top and ¼ inch at the bottom. In pouring in an open mould of this -type, pour the lead in each groove at one end, so that the dross will -all gather in one spot. Never move the ladle along the groove when -pouring, as this will scatter the dross and make the entire stick dirty. - -When poured at one end only, a short length of the stick may be broken -off, thus removing all the dross. - -Dusting the mould occasionally with Ambu mould compound will produce -better castings and permit greater speed in the work. - - - AMBU PLATE BURNING RACK - -The building of groups, even after the plates and post straps are -secured is a job that requires quite a lot of skill. Before the plates -can be burned to the strap, they must be absolutely parallel, must be -the correct distance apart, and the top surface of the strap must be at -right angles to the surface of the plates. - -The Ambu Plate Burning Rack, Figure 15, has been designed to easily -secure the proper conditions. It consists of a wooden base with six -different sets of slots properly spaced which cares for 98% of the -batteries on the market. The guide bar or “comb” on top is slotted to -match up with the base. (See figure 15.) - -[Illustration: Figure 15[1]] - -The positions of the base and comb are so arranged that the plates are -securely held on opposite corners, at exactly the right distance apart -and are absolutely straight and parallel. - -The wooden base prevents the plate proper from coming in contact with -any metal and thus eliminates any possibility of later trouble due to -impurities in the cell. - -[Illustration: Figure 16[1]] - -In order to accommodate the different sizes and spacings, the comb can -be adjusted vertically and the slots are arranged in groups of different -spacings. These adjustments are flexible enough to allow the setting up -of practically all the various groups used in the different makes and -type of batteries. - -Special fittings are provided so that after the plates and post are -properly set a form can be built on the comb which not only locks the -plates in the comb but prevents the hot lead from running off while -burning and makes the finished strap of exactly the proper dimensions to -properly fit into the jar. - -For use in the smaller shop the small Ambu Plate Burning Rack, Figure -16, is recommended. It has all the features of the larger rack but the -spacings of the combs limit it to the ^7⁄_{64}" and ⅛" spacings such as -are found in all the popular batteries. - ------ - -Footnote 1: - - Prices, page 17 - - - AMBU POST BUILDERS - -After the top connectors have been drilled off and the group is to be -reassembled in the repaired battery, in order to make a good quick weld -to the top strap, the post must be built up to its original height. - -[Illustration: Figure 17. See bottom of page] - -The Ambu Post Builders, Figure 17, have been built to speed up the post -building process. They are made of high grade steel and are of the -proper size to rebuild all the standard battery posts. - -Simply place the proper Ambu Post Builder on the stub post, and burn in -molten lead to the proper height. The construction is such that the post -builder is easily removed, leaving a new and perfectly sized post for -burning to the cell connector. - -The set of ten, illustrated in Figure 17, covers all standard makes of -batteries. - - * * * * * - - =Following are prices of equipment illustrated in preceding pages= - which may be purchased from the Battery Appliance Division, American - Bureau of Engineering, Inc., 2632 Prairie Avenue, Chicago, or from - your Jobber. - - Adjustable Screw Mould (Fig. 13) $12.50 - Battery Post Builders.

It would not pay the battery man to equip his shop -to manufacture any of these items.</p> - -<div id='fig1' class='figcenter id002'> -<img src='images/i_005.jpg' alt='' class='ig001' /> -<div class='ic003'> -<p>Figure 1</p> -</div> -</div> - -<p class='c000'>The same is true of the rubber parts, the jars and top covers. A -dozen different sizes in stock will take care of nearly all the various -makes and models of batteries which come in for repair.</p> - -<p class='c000'>With the lead parts, however, the conditions are entirely different. -All the active and wearing parts are made of lead, or its compounds, -and practically every battery that needs repair, needs some of them -replaced. Then again there is a much greater variety in the design of -these parts and the up-to-date shop, in order to give real service, must -carry a large assorted stock of end connectors, connector straps, plate -straps and posts.</p> - -<p class='c000'><span class='pageno' id='Page_4'>4</span>In speaking of lead parts, however, the plates are to be considered -on the same basis as the rubber parts or wooden boxes, because it would -not pay the ordinary battery shop to try and cast grids, mix paste and -manufacture plates. It is much more satisfactory to purchase plates -made by a responsible manufacturer who has the facilities and capital -to properly develop his formulae and processes.</p> - -<p class='c000'>Every battery that has to be opened must have the top connectors -drilled off as in Fig. <a href='#fig1'>1</a>, which naturally makes a lot of lead chips. These -drillings have to be cleaned off before proceeding with the repair and -can, with no loss of time, all be collected, as in Fig. <a href='#fig2'>2</a>, and saved. Then -the old sulphated end connectors and parts from “junked” batteries -accumulate very fast.</p> - -<div id='fig2' class='figcenter id004'> -<img src='images/i_006.jpg' alt='' class='ig001' /> -<div class='ic003'> -<p>Figure 2</p> -</div> -</div> - -<p class='c000'>This then is the situation—The battery service station is constantly -in need of new lead parts. Should they be obtained from a manufacturer -at a price that includes material, labor and the manufacturer's -profit—OR—should equipment be purchased that will permit of moulding -these same parts from the accumulated scrap lead at a cost of nothing -but the time employed in pouring, with no cost for material and no -“Profits” added?</p> - -<p class='c000'>No matter how cheap you think you are buying your lead parts, -just compare the market price per pound on lead with the weight of a -few of your “cheapest” ones.</p> - -<p class='c000'>It is now common practice to melt some of this accumulation of -scrap lead and pour it into sticks or bars for use in lead burning on -<span class='pageno' id='Page_5'>5</span>repair work. A great amount, especially old groups, is generally sold -at a low price in order to get it out of the way. The one important -fact, and one generally overlooked, is, that the battery man who melts -lead and moulds it into sticks for lead burning, certainly is able to melt -the same metal and mould it into the lead parts he requires, provided, -of course, that he has the proper moulds.</p> - -<p class='c000'>Many a wide awake man has whittled a wooden mould for some -part that he wanted in a hurry and couldn't wait for the manufacturer -to deliver. Naturally this condition, really an effort to render service -to the customer, created a demand for moulds of a permanent character.</p> - -<p class='c000'>In an effort to supply this demand, the moulds that have been produced -were all made for some individual part, were light in weight and -easily became overheated, making them hard to handle and often burning -the workman's hands.</p> - -<div id='fig3' class='figcenter id005'> -<img src='images/i_007.jpg' alt='' class='ig001' /> -<div class='ic003'> -<p>Figure 3</p> -</div> -</div> - -<p class='c000'>From a business standpoint, it would certainly be mighty profitable -for a battery shop to be able at a moment's notice, to convert junk lead -into new salable parts. In addition to the large profit from the sale -of these new parts, another good feature, is that, instead of tieing up a -lot of capital in stock, the new parts can be made as needed, without a -cent of investment.</p> - -<p class='c000'>From a service standpoint, it is a cheaper and faster process to cast -a new top connector than to spend a lot of valuable time, whittling an -old one so that it can be used again.</p> - -<p class='c000'>How much time have you or your men wasted cleaning up an old -terminal as in Fig. <a href='#fig3'>3</a>, so that you could burn it on again?</p> - -<p class='c000'><span class='pageno' id='Page_6'>6</span>All new connectors and terminals put on a rebuilt or reinsulated -job make the customer feel that he is getting a real repair. He sees a -new finished job.</p> - -<p class='c000'>From an electrical standpoint, the new parts mean better work, -because better burning can be done, certainly a new connection will -allow the battery to deliver more current than an old partly sulphated -one could ever do.</p> - -<h3 class='c007'>CAN YOU MAKE GOOD LEAD CASTINGS?</h3> - -<p class='c008'>The question that naturally comes up is, can the ordinary battery -man make good lead castings? We will answer “Yes,” very emphatically. -There is nothing mysterious about the work and all the talk of -alloys, compounds and formulae does not mean a great deal.</p> - -<p class='c000'>Pure lead is not hard or rigid enough to make good battery parts, -therefore, it is necessary to add some other metal that will provide the -strength, not be affected by the acid and not increase the resistance -electrically. Antimony has all the necessary qualities, and is, therefore, -commonly used by mixing it with the pure lead.</p> - -<div id='fig4' class='figcenter id002'> -<img src='images/i_008.jpg' alt='' class='ig001' /> -<div class='ic003'> -<p>Figure 4</p> -</div> -</div> - -<p class='c000'>The various manufacturers recommend from 2 to 12 percent antimony, -as the proper combination, but in buying new pig lead for castings, -a 4 percent antimony compound is very satisfactory.</p> - -<p class='c000'>In using old battery lead, however, due to chemical action the proportion -of antimony is apt to be too high to produce perfect castings. -This usually shows up by cracks or shrinkage, as in Figure <a href='#fig4'>4</a>. To overcome -this trouble, pure lead is added, until a perfect casting is made. -Pure lead can be purchased (in the form of bars, lead pipe, or sheet -lead) from a manufacturer such as the National Lead Company—your -accessory jobber, the local plumber, or the junk dealer. When buying -from a junk dealer, however, care <strong>must</strong> be taken that there is no solder -or tin present.</p> - -<h3 class='c007'>PREPARATION OF THE LEAD</h3> - -<p class='c008'>In order to pour the lead some means of melting and a proper container -must be provided.</p> - -<p class='c000'><span class='pageno' id='Page_7'>7</span>As pure lead melts at about 620°F., and antimony at 785°F., an -ordinary gas flame will furnish sufficient heat. For the small shop, -without an artificial gas supply, a plumber's furnace which can be -secured from Hardware Jobber or Plumber Jobber will work satisfactorily. -See page <a href='#Page_19'>19</a> for gas melting pots.</p> - -<p class='c000'>An ordinary cast iron solder pot will be found the most suitable -container. It should be about 8 inches in diameter.</p> - -<p class='c000'>It is advisable to obtain as large a pot as above, because for steady -pouring a sufficient supply of melted metal should always be available. -Then too, the constant addition of scrap or pig lead in a small pot will -often change the proportion of antimony so that the castings crack and -have to be melted over again.</p> - -<p class='c000'>Wash the pot thoroughly with gasoline or kerosene to remove all -traces of oil. Then after it has been carefully dried, put it over the -flame and heat it gradually. Do this before putting in any lead.</p> - -<p class='c000'>The only other equipment necessary to handle the melted lead is a -ladle. For this purpose a malleable iron melting ladle five inches in -diameter should be purchased. It can be used for stirring, skimming -and pouring, and the type with a spout, illustrated in Fig. <a href='#fig5'>5</a> will -be found most suitable. The ladle should be cleaned and treated -exactly like the melting pot.</p> - -<div id='fig5' class='figcenter id002'> -<img src='images/i_009.jpg' alt='' class='ig001' /> -<div class='ic003'> -<p>Figure 5</p> -</div> -</div> - -<p class='c000'>The scrap or pig lead can now be put in the pot and melted. It is -a time saving plan to pick out carefully all the pieces of wood, rubber -and sealing compound from the scrap lead before it is put in the pot. -Old plates are not worth while melting, but a lot of good lead can be -salvaged by sawing the strap and post off old groups. Above all -things make sure that no wet parts or moisture of any kind ever gets -into the lead pot.</p> - -<h3 class='c007'>CLEANING THE LEAD</h3> - -<p class='c008'>As the lead melts most of the dross or dirt will come to the top and -float. When all the pieces are melted stir the lead with the ladle and -then skim off all the dirt.</p> - -<p class='c000'>To help the cleaning process a piece of paraffin can be dropped into -the pot. After it has burned, the dross is more easily skimmed off.</p> - -<p class='c000'>Another method of cleaning is to add to every ten pounds of metal, -one teaspoonful of equal parts of powdered rosin, borax and flour of -<span class='pageno' id='Page_8'>8</span>sulphur. Stir this compound in a little and when the lead is at the proper -temperature there will be a flare, flash or a little burning. A sort of -tinfoil popcorn effect will be noticed floating on top of the metal. Continue -stirring until this melts down and then skim off the soft particles.</p> - -<p class='c000'>An easy way to test the temperature of the melted lead is to insert -the end of a pine stick for a moment. When the wood blackens or burns, -the lead is hot enough to pour.</p> - -<p class='c000'>Whenever the lead is in melted form and exposed to the air, as in -the iron pot, there will be a slight oxidation take place which appears -as a yellowish-red scum. Do not confuse this with the dross and dirt -which is to be skimmed off, but if the scum gets thick, then skim it off -before pouring any of the metal.</p> - -<h3 class='c007'>PREPARING THE MOULD</h3> - -<p class='c008'>One of the greatest difficulties in making lead castings has been to -get the metal to completely fill the mould. There are several reasons -for this, but they can easily be overcome.</p> - -<p class='c000'>If the mould, which is generally made of iron, is very cold, it will -chill the melted lead and cause it to become solid before it has reached -all parts.</p> - -<p class='c000'>The surface of a cast iron mould is very porous, and the melted lead, -partially entering the pores of the iron, is held back long enough to -chill and set.</p> - -<p class='c000'>To remedy these faults, it is sometimes advisable to heat the mould -in order to get perfectly shaped castings.</p> - -<p class='c000'>To close the pores of the iron moulds they are sometimes “smoked” -with a flame like that of “Prest-O-Lite” gas or else dusted with graphite.</p> - -<div id='fig6' class='figcenter id002'> -<img src='images/i_010.jpg' alt='' class='ig001' /> -<div class='ic003'> -<p>Figure 6</p> -</div> -</div> - -<p class='c000'>The AMBU mould compound has been developed to eliminate the -<span class='pageno' id='Page_9'>9</span>necessity for heating or smoking the mould—it remedies all the pouring -troubles and in addition, has chemical ingredients that aid in preventing -the mould from rusting. AMBU mould compound is placed in a little -sack, contained in each can, and the surface of the mould dusted with -the sack, as shown in Figure <a href='#fig6'>6</a>.</p> - -<p class='c000'>The compound completely fills the pores of the iron, produces perfect -castings with a cold mould and prevents the finished part from sticking. -It does not wear off as quickly as the “smoke,” and dusting from time -to time, while castings are being made will produce a high polish on -the mould surface which will result in even better castings.</p> - -<p class='c000'>The mould in Figure <a href='#fig6'>6</a> is the new AMBU Washburn combination -link mould, which casts 15 parts, being reversible much like the ordinary -“waffle iron.” The side being “dusted” casts four top connectors of -different lengths.</p> - -<h3 class='c007'>POURING THE LEAD</h3> - -<p class='c008'>Placing the mould as in Figure <a href='#fig7'>7</a>, the lead is poured in the four -openings until the metal projects slightly above the top.</p> - -<p class='c000'>To pour properly first skim the dross as previously explained, then -with the ladle, push the film of oxide away and dip into the clean pure -lead. Pour steadily until the mould is filled and the metal projects -slightly above the top. As it cools there will be quite a little contraction -which takes up most of the excess lead.</p> - -<div id='fig7' class='figcenter id002'> -<img src='images/i_011.jpg' alt='' class='ig001' /> -<div class='ic003'> -<p>Figure 7</p> -</div> -</div> - -<p class='c000'><span class='pageno' id='Page_10'>10</span><strong>Never</strong>, under any conditions, stop pouring with a mould partially -filled.

Never put anything in the lead pot that is not perfectly dry. -A few drops of water in a pot of melted lead will cause an explosion -and the hot lead will be thrown all over the shop burning and perhaps -blinding the workman.</p> - -<p class='c000'>2. Have all moulds clean and dry.</p> - -<p class='c000'>3. Keep the melted lead in the lead pot clean at all times.</p> - -<p class='c000'>4. Always completely fill each mould at one pouring.</p> - -<p class='c000'><span class='pageno' id='Page_11'>11</span>5. Dust moulds well with Ambu mould compound before pouring.</p> - -<p class='c000'>6. When castings “shrink” and crack, add pure lead to that in the -pot until the trouble is remedied.</p> - -<p class='c000'>7. Be sure melted lead is of proper temperature, by pine stick test, -before starting to pour.</p> - -<p class='c000'>8. Remove castings as soon as they set, to prevent the mould -from becoming too hot.</p> - -<p class='c000'>9. A perfect casting, that breaks when taken out of the mould, -has probably not been allowed sufficient time to “set” or cool properly.</p> - -<p class='c000'>10.

If a casting -should stick, pry it out.</p> - -<h3 class='c007'>AMBU COMBINATION LINK MOULD</h3> - -<p class='c008'>Using both sides, this mould casts five of the most used connectors -for all batteries, using Standard Jars, 7-9-11-13-15 Plate four end connectors -(two Dodge Tapers and two Standard Tapers, Negative and -Positive), one end connector, ⅜-inch wire leed used on 12-volt Maxwell -and other cars using wire leed.
