Improvements in Electric Battery Cases, to render the Contents of
the Cells Unspillable; to facilitate the introduction of the Electro-
lyte into the Cells; to enable the Level of the Liquid to be easily
ascertained; and to facilitate inspection of the Interior.
I, GIUSEPPE FABBRO, Morton House, Trott Street, Battersea, S.W., Electrical
Engineer, do hereby declare the nature of this invention to be as follows:-
A case with one or more cells and a cover with sloping sides, fitting into the
case and sealed with a plastic composition. The cover has two compartments,
with pin holes, to allow gas to escape and liquid from the cells to run back. It
may have in the centre a conical hole, through which the sealing composition may
be more easily passed.
The case has a projection on one side, through which the positive and negative
terminals pass into the contact chamber.
This projection has holes closed with ebonite screws, each hole giving access to
a cell; through which the electrolyte can be passed and the level of the liquid.

Improvements in Electric Battery Cases, to render the Contents of
the Cells Unspillable; to facilitate the introduction of the Electro-
lyte into the Cells; to enable the Level of the Liquid to be easily
ascertained; and to facilitate inspection of the Interior.
I, GIUSEPPE FABBRO, Morton House, Trott Street, Battersea, S.W., Electrical
Engineer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My invention relates to the construction of battery cases in which a liquid
electrolyte is used, and has for its object the rendering the same unspillable; to
enable the same to be more easily introduced into the cells; to make inspection
of the interior of the battery easier; and to enable the level of the liquid in the
cells to be at any time ascertained. It consists of the following: A case (Fig. A)

made of ebonite or other material, with one or more compartments or cells,
according to the amount of E M F it is desired to develope. The case has a cover
rig. B), the upper part of whose sides slopes at h," while the lower part 2
of the cover exactly fits into each cell. The space at "z" is filled with a com-
position to seal the case and cover together. The cover is divided into two
compartments, "a," "," by means of a cup c," made of ebonite or other con-
venient material, which is provided with a sealed lid "d." The cover, the lid and
the bottom part of the cup are provided with pin holes, m; which allow the gas
to pass through; while any of the liquid which may have been drawn up, runs
back into the cell.

The cover has a hole, , to facilitate the sealing of the internal part of the
apparatus, in order to isolate the cells from each other. A projecting block,
(Fig. C.) is fitted on the side of the case A. This block is provided with two
terminals, e. e., positive and negative, whose lower extremities enter the connec-
tion chamber f. f. The block has holes at 9. g., closed with ebonite screws, each
hole communicating with one cell. To fill the battery, the screws are removed
and the electrolyte is poured into the holes; the screws being then replaced. The
connection chamber ff. has two holes at y y, through which the electrodes of
the primary or secondary element are passed in order to be attached to the
terminals e e.
The partition, k, in the connection chamber f f is designed to prevent moisture
from passing from one connection to the other and so causing a short circuit.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1st. That by means of the arrangement of the cover and cup (Fig. B.) the
battery is rendered unspillable.
2nd. That by means of the holes, 9, 9, (Fig. C) the introduction of the electro-
lyte into the cells is made more easy. Also that the level of the liquid can be
more easily ascertained, as it is not necessary to remove the cover of the battery.
3rd. That inspection of the interior of the cell or battery is made easier by the
arrangement of the cover and cup (Fig. B), which can be removed as one piece.
