oulded into the cover. These bushings fit around the
posts, and are burned to the posts and top connectors, Figs. 243 and
244, thus giving leak proof joints between the cover and the posts. In
burning on the connectors, melt bottom edge of hole first, then top of
post and cover bushing, and melt in your burning lead slowly.

PREST-O-LITE BATTERIES

[Fig. 245 Old type Prest-O-Lite battery with lead bushings
that screw up into cover]

Some of the old Prest-O-Lite batteries have a lead bushing around the
post, Fig. 245, similar to the U. S. L. batteries. This will make a
perfectly tight seal, provided that you screw the bushing up tight.
The new types of Prest-O-Lite batteries have a "Peened" post seal,
special instructions for which follow.

The general instructions for rebuilding batteries given on pages 328
to 374 apply to Prest-O-Lite batteries in every respect. The "Peened"
post seal is, however, a special construction, and directions for
working on this seal are as follows:

[Fig. 246 Prest-O-Lite Element Locked]

All Prest-O-Lite batteries designated as Types WHN, RIJN, BHN, JFN,
KPN, and SHC, have a single moulded cover which is locked directly on
to the posts of the element. This feature is the result of forcing a
solid ring of lead from a portion of the post, projecting above the
cover, down into a deep chamfer in the top of the cover. Figs. 246 and
247 show this construction.

This construction makes a solid unit of the cover and element, which
does away with the sealing compound, washers, nuts, etc., for making
the acid tight seal around the posts.

The locking operation requires some special instructions and shop
equipment for assembly and all repairs which involve removal from and
replacement of the cover on the element.

The majority of battery repairs such as renewal of jars, separators,
straightening of plates, and removal of sediment, can be made without
separating the cover and element. In such cases the connectors are
drilled off, compound is softened and removed from around the covers
and the complete unit is removed from the cell. It may be handled
throughout the repair as a unit, and the cover serves as a bridge to
hold the plates of both groups in line just as they remain in the jar.
