purpose. Before
driving on the old collar, the post should be expanded slightly by
driving the point of a center-punch into the shoulder on the post.
Instead of expanding the shoulder a new collar may be used.

Fig. 272 shows the soft rubber gasket being placed over the post, and
shows the construction of the cover with its recess to fit the gasket.

Fig. 273 shows the lead collar being placed over the post after the
cover is in place.

Fig. 274 shows the special long lipped tongs required to force the
collar down on the post shoulder. One lip of the tongs has a hole into
which the post fits. The necessary driving force may be obtained by
applying pressure to the ends of the lips of the tongs With an
ordinary vise. This forces the cover down on the rubber gasket to make
the acid-tight seal.

WESTINGHOUSE BATTERIES

Westinghouse batteries have a special seal between covers and posts,
as shown in Fig. 275. A lead foundation washer (J) is set around the
post. A "U" shaped rubber gasket, (K) is then forced between the cover
and post, with the open end up. The lips of this gasket are tapered,
with the narrow edge up. A tapered lead sleeve (L) is then forced
between the lips of gasket (K), thereby pressing the inner lip against
the post and the outer lip against the cover.

[Fig. 275 Westinghouse battery, partly dis-assembled]

The lead sleeve is held in place by broaching or indenting the collar
on taper lead sleeve into the posts.

To break the seal, a hollow reamer or facing tool, fitted into a drill
press or breast drill, is slipped over the post. A few turns will
remove that part of the sleeve which has been forced into the post.
Remove sealing compound around cover, remove group from cell. The
cover can then be lifted off and if any difficulty is experienced, it
can easily be removed by prying up cover with screwdriver. After
removing the cover, the tapered lead sleeve and "U" shaped gasket can
be removed. If these instructions are followed, the "U" shaped gasket
and taper lead sleeves can be used when battery is reassembled.

With the addition of the foregoing instructions on the post seal, the
standard directions for rebuilding batteries given on pages 328 to 374
apply to Westinghouse batteries.
