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.)

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.

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.

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.

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.

Johnson Direct-jet Lead Melting Pots

In line with our desire to serve the Battery Service Stations of the country, we have arranged to offer the Johnson Direct-jet Gas-fired Melting Pots. These furnaces use either natural or manufactured gas. They embody a special patented Gas-regulator which permits of a quick change in the size of the gas orifice, by the turn of a wrench.

This Regulator throws a sharp, clean jet of gas straight up the center of the mixing tube, giving the nearest approach to 100% combustion that can be imagined.

=No Blowers or Forced Draft are necessary. City gas pressure is enough.=

=No. 300 Pot.= Melts 150 lbs. lead at a charge, using only 40 cubic feet of city gas per hour. Has 3 Direct-jet Burners. No forced draft necessary. Height, 28 inches; weight, 100 lbs. Price f. o. b. Cedar Rapids, Iowa, $25.00. Stock No. MJP1.

=No. 8 Combined Torch and Pot.= Melts 25 lbs. of lead at a charge. Height, 14 inches; weight, 9½ lb. Single adjustable burner, with pilot. Can be used as an efficient hand torch. Consumes 20 to 25 cubic feet of gas per hour. Price complete with 6 inch Pot, as shown, f. o. b. Cedar Rapids, Iowa, $9.00. Stock No. MJP2.
