PROVISIONAL SPECIFICATION.
An Improvement in Tanks or Cells for Electrolysis and like
purposes.
We, FRANCIS EDWARD ELMORE, and ALEXANDER STANLEY ELMORE, of
Thwaite Gate, Leeds, in the County of York, Electrometallurgists, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the construction of a tank or cell suitable for electrolysis,
containing cells for secondary batteries, and similar purposes.
The tank or cell consists of a wooden hox which is preferably lined internally
with canvas or other texture within which box is placed another wooden box
preferably covered externally with canvas or texture, leaving a narrow space
between the two boxes, which may be from half an inch to an inch wide.
The two boxes are held in position by small distance pieces having very narrow
contacts with the boxes. The space between the two boxes is then filled up with
soft plastic material, preferably of bituminous character, poured in while the inner
box is firmly held in position.
An advantage of this construction is that the inside bar supports the bituminous
composition, which may thus be made so soft that there is no danger of it cracking,
either with changes of temperature, or by the expansion or contraction of the tank
when empty or full.

COMPLETE SPECIFICATION.
An Improvement in Tanks or Cells for Electrolysis and like
purposes.
We, FRANCIS EDWARD ELMORE, and ALEXANDER STANLEY ELMORE, of
Thwaite Gate, Leeds, in the County of York, Electrometallurgists, 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:―
This invention relates to the construction of a tank or cell suitable for electrolysis,
containing cells for secondary batteries and similar purposes, as we shall describe
referring to the accompanying drawings.
Figs. 1 are 2 are respectively a longitudinal and a transverse section of a tank or
cell according to our invention.
The tank or cell consists of a wooden box A within which is placed another
wooden box B leaving a narrow space C between the two boxes, which may be from
half an inch to an inch wide. The two boxes are held in their relative position by
small distance pieces D having very narrow contacts with the boxes. The space C
between the two boxes is then filled up with soft plastic material, preferably of
bituminous character, poured in while the inner box is firmly held in position,
either by screws as shewn or it might be by wooden pins or by a ledge E indicated
by dotted lines in Fig. 2 covering the upper edges of both boxes and secured to
them.
The bituminous composition being thus supported on both its sides may be made
of so soft consistence that there is no danger of its being caused to crack by changes
of temperature, or by the expansion or contraction of the tank when it is filled or

page_text: emptied. We find a suitable composition for filling the space between the boxes to
be a mixture of pitch, rosin, and plaster of paris in about equal parts along with
such a proportion of resin oil, as will give the whole mass when it is cold, a
consistence such as putty.
In some cases the inner box may be covered externally with canvas or other fabric
and the outer box may be similarly lined internally, but, when the pieces of wood
which constitute the boxes have no wide gaps between them, such covering and
lining are unnecessary.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A tank or cell for electrolysis and like purposes consisting of an inner and an
outer box of wood with a space between them filled with plastic bituminous com-
position, substantially as described.
