THE TITAN BATTERY

The Titan Battery is built along standard lines, as far as cases,
plates, separators, and jars are concerned. The ribs of the grids not
arranged at right angles but are arranged as shown in Fig. 293. Each
pellet of active material is supported by a diagonal rib on the
opposite face of the grid.

[Fig. 293a Titan Battery grid]
[Fig. 293b Titan Post Seal construction]

The Titan Post Seal is shown in Fig. 293. A soft rubber gasket (G) is
slipped over the post, and rests on a shoulder (F) on the post. The
cover has a channel which fits over the gasket and prevents the gasket
from being squeezed out of place when the cover is forced down on the
gasket. The post has two projections (DD), as shown, the lower surface
of each of which is inclined at an angle to the horizontal. A lock nut
(H), which has corresponding projections (IJ) is slipped over the post
as shown at (0), and is given a quarter turn. The top surfaces of the
projections on the lock-nut are inclined and as the locknut is turned,
the projections on the post and nut engage, and the cover is forced
down on the gasket (G). To lock the nut in place, a lock washer (L) is
then slipped over the post, the projections (MM) fitting into spaces
(KK) between the projections on the post and nut, thus preventing the
nut from turning. A special wrench is furnished for turning the
lock-nut. The cell connectors rest on the tops of the lock washers and
keep them in place.

The overhauling of Titan batteries should be done as described on
pages 328 to 374.

FARM LIGHTING BATTERIES SPECIAL INSTRUCTIONS.
--------------------------------------------

Although the large Central Station Companies are continually extending
their power lines, and are enlarging the territory served by them, yet
there are many places where such service is not available. To meet the
demand for electrical power in these places, small but complete
generating plants have been produced by a number of manufacturers.
These plants consist of an electrical generator, an engine, to drive
the generator, and a storage battery to supply power when the
generator is not running. The complete plants are called "House
Lighting," "Farm Lighting," or "Isolated" plants.

The batteries used in these pl
