asts practically all
the cell connectors used on standard 7, 9, 11, 13 and 15 plate
batteries. This mould is similar to the Link Combination Mould shown
in Figure 103.

[Fig. 108 Castings made in strap mould]

Figure 106 shows a production type strap mould which is designed to be
used by large battery shops. Forty-two styles of straps are, cast by
this mould. This mould has an indexing device as shown in Figure 107,
which is adjusted by means of a screw for moulding the straps for any
number of plates from seven to nineteen. Figure 109 shows some of the
castings which are made with this mould.

[Fig. 109 Terminal mould and castings made in it]

Figure 109 shows a Terminal Mould which casts five reversible end
terminal connectors, a cable connector, such as is used on the
Maxwell battery, and two washers often needed in making a tight
connection.

[Fig. 110 Screw mould]

Figure 110 shows a Screw Mould which casts standard square lead leads
on four screws in one operation, two 5/8 inch and two 3/8 inch. This
mould has a screw adjustment in the base which makes each cavity
adaptable to any length screw.

EQUIPMENT FOR WORK ON CASES

The acid proof asphaltum paint, paint brushes, wood chisels, wood
plane, and earthenware jars are all standard articles.

Figure 111 shows a battery turntable which is very convenient when
painting cases, lead burning, etc.

TOOLS FOR GENERAL WORK

Most of the articles in this list require no explanation. Some of
them, however, are of special construction.

Separator Cutter. Some battery supply houses sell special separator
cutters, but a large size photograph trimmer is entirely satisfactory.

is made of heavy hardwood timbers, and may be set on a bench or
mounted on the wall. A set of lead coated troughs carry away the acid
which is squeezed from the plates.
