ctors and terminals as usual.
2. Saw off the posts close to the covers, taking care not to injure
the covers; This will separate the posts from the cover inserts, and
the covers may be removed.
3. In reassembling, Ale off the top of the cover insert at "A" (Fig.
292).
4. Put covers on so that their tops will be 1/32 inch above the top
edge of the jars, tapping the covers lightly with a small hammer.
5. Brush the top of post and cover insert perfectly clean. Now make a
burning form consisting of a ring 1-1/8 inside diameter and 1-5/8 inch
outside diameter and 3/16 to 1/4 inch high. Set this over the stub
post and cover. With a hot lead burning flame melt the top of the post
and cover insert together. Then melt in lead up to the top of the
special burning form (Fig. 286). Then remove the form.

6. Set post builders on the part of the posts which has been built up
and build up the posts as usual, Fig. 286. Then burn on the connectors
and terminals.
Willard Gasket Type Batteries
Fig. 287 shows this type of construction, used on types SJRG and SLWG.
Fig. 288 shows the seal in detail. A soft rubber gasket is slipped
over the post, and the cover is pushed down over the gasket. For
removing the covers, have a cover removal frame made as shown in Fig.
289. Fasten the frame to a solid wall or bench so that it will
withstand a strong pull. In rebuilding this type of battery proceed as
follows:
[Fig. 287 Willard Gasket Seal Battery cross section]
1. Drill off the connectors and terminals, leaving the post stubs, as
high as possible, since the only way of removing the plates is by
grasping the post stubs with pliers.
[Fig. 288 Details of Willard Gasket Seal]
2. Steam the battery to soften the sealing compound and lift out the
plates as usual.
3. To remove covers. Saw the post stubs off flush with the covers.
Place the element in the cover removal frame (Fig. 289) and pull
steadily on the element. A little swaying motion from side to side may
help in loosening the covers. If any of the gaskets remain on the
posts when the covers are removed, replace them in the cover and
thoroughly dry the inside with a rag.

4. To replace covers. With a rag or tissue paper wipe off the posts
and then dry them thoroughly with a soft flame.
