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.
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.
