I, CHARLES MOSELEY of the Chapelfield India rubber Works in the City of
Manchester and County of Lancaster India rubber Manufacturer do hereby declare
the nature of my invention for IMPROVEMENTS IN BOXES OR CELLS FOR PRIMARY
AND SECONDARY ELECTRIC BATTERIES to be as follows:-
These Improvements relate to the boxes or cells of primary or of secondary
electric batteries.
I construct these boxes of wood to any desired pattern or form and within each
box I place a loose lining of india rubber moulded approximately to the internal
form and dimensions of the box. The india rubber lining is by preference formed
of soft vulcanite compound. Around the top outer edge of the box I form a rebate
into which the edge of the lining is turned and secured by fillets which may be
nailed in position. Outside these fillets I plant or secure strips of wood which
project above and surround the top of the box. The fillets are preferably of such
a size that they do not completely fill the rebate so that there is left between the
top of the box and the surrounding strips a shallow trough or groove. The space
between the top inner edges of the box and the similar edges of the strips is then
filled with paraffin wax or other analogous substance.
The loose india rubber linings permit the expansion or contraction of the boxes
and prevent leakage and the paraffin wax or other analogous substance prevents
'creeping" of the sulphuric acid or other solution.

I, CHARLES MOSELEY of the Chapelfield India-rubber Works in the City of
Manchester and County of Lancaster Indiarubber Manufacturer do hereby declare
the nature of my invention for IMPROVEMENTS IN BOXES OR CELLS FOR PRIMARY
AND SECONDARY BATTERIES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
These Improvements relate to the boxes or cells of primary or of secondary
electric batteries and have for their object to prevent leakage while permitting
expansion or contraction of the cells or boxes and to prevent "creeping." of-the
sulphuric acid or other solution.
"B
And in order that this Invention may be more readily understood and carried
into practical effect I have hereunto appended a sheet of Drawings the Figures
thereon having similar parts indicated by similar letters and reference being herein-
after had thereto..
Fig. 1 is a longitudinal section and Fig. 2 is a cross section. of a cell: or box
having these Improvements applied thereto.
I construct the cell or box of wood to any desired pattern or form and within
each box I. place a loose watertight lining A of indiarubber moulded approximately
to the internal form and dimensions of the box or cell. The indiarubber lining is
by preference formed of soft vulcanite compound. Around the top outer edge of
the box or cell I form a rebate B into which the edge of the lining is turned and
secured by fillets C C which may be nailed or otherwise secured in position.
Outside. these fillets I "plant" or secure strips of wood D D. which project above
and surround.the top of the box or coll. The fillets C C:may be of such a size that
they do not completely fill the rebates or they may fill the rebates and project
slightly beyond in which case their top edges should be bevelled. In either case
there must be left between the top inner edge of the box and the surrounding strips
a. shallow.trough.origroove.. This space or trough F between the top inner edges
of the box and the similar edges of the strips D D is then filled with paraffin wax,
ozokerit or other analogous water repellant substance which will not act upon the
indiarubber.
=
The loose india rubber lining permits the expansion of the box or coll and
prevents leakage while the paraffin wax or other analogous material prevents
creeping" of the sulphuric acid or other solution.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
↓
(1.) In a box or cell for a primary or secondary electric battery a loose water-
tight indiarubber lining, substantially as hereinbefore set forth and described.

page_text: (2.) In a box or cell for a primary or secondary battery, a strip of paraffin wax,
ozokerit or analogous material contained within a trough or grove formed in or
upon the top edge of the box or cell, substantially as herein before set forth and
described and as illustrated on the accompanying sheet of Drawings.
(3.) In a box or cell for a primary or secondary battery, a loose watertight india-
rubber lining in combination with a strip of paraffin wax, ozokerit or analogous
material, substantially as hereinbefore set forth and described and as illustrated on.
the accompanying sheet of Drawings.
