Improvements in Electric Batteries Working with Two Liquids or
Electrolytes.
We, HENRY WEYMERSCH of 2 Victoria Mansions, Victoria Street in the City of
Westminster, Chemist and ROBERT MCKENZIE also of 2 Victoria Mansions in the City
of Westminster, Gentleman do hereby declare the nature of this Invention to be as
follows:-
This Invention relates to the construction of electric batteries working with two
liquids or electrolytes and has for its object to provide a simple arrangement of cells
into which the several liquids or electrolytes can be supplied and from which they
can be withdrawn with great facility. According to this Invention the vessel or casing
in which the cells are formed is divided into compartments by porous and non-porous
partitions which may consist of plates let into grooves in the interior of the vessel or
casing, or porous pots may be used. The cells which are to contain the one electro-
lyte all communicate with each other by means of passages which lead to one common
outlet through which the electrolyte from all the compartments can be withdrawn
when required. The passages preferably are made in the substance of the bottom of
the vessel or casing and may be lined with a material impervions to, and not injured,
by the electrolyte. For instance a vulcanite tube may be led along the bottom of the
battery and into this vertical borings or holes may lead from each cell containing
the said electrolyte. The outlet end of this tube is provided with an outlet. tap.
Similarly the cells containing the other of the electrolytes are connected with a
similar passage or tube. By pouring the respective electrolytes into either of the
cells destined to receive them each electrolyte passes therefrom into the other of the
cells for each electrolyte until the desired level is reached and when it is desired to
draw off either electrolyte it can readily be done by opening the tap on the outlet
pipe leading from the cells from which the electrolyte is to be withdrawn.

Improvements in Electric Batteries Working with Two Liquids or

We HENRY WEYMERSCH of 2 Victoria Mansions Victoria Street in the City of
Westminster Chemist and ROBERT MCKENZIE also of 2 Victoria Mansions in the
City of Westminster Gentleman 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 electric batteries working with two
liquids or electrolytes and has for its object to provide a simple arrangement of cells
into which the several liquids or electrolytes can be supplied and from which they can
be withdrawn with great facility. According to this Invention the vessel or. casing
in which the cells are formed is divided into compartments by porous and non-porous
partitions which may consist of plates let into grooves in the interior of the vessel or

page_text: casing, or porous pots may be used. The cells which are to contain the one electro-
lyte all communicate with each other by means of passages which lead to one common
outlet through which the electrolyte from all the compartments can be withdrawn
when required. The passages preferably are made in the substance of the bottom of
the vessel or casing and may be lined with a material impervious to and not injured
by the electrolyte. For instance a vulcanite tube may be led along the bottom of
the battery and into this vertical borings or holes may lead from each cell containing
the said electrolyte. The outlet end of this tube is provided with an outlet tap.
Similarly the cells containing the other of the electrolytes are connected with a.
similar passage or tube. By pouring the respective electrolytes into either of the
cells destined to receive them each electrolyte passes therefrom into the other of the
cells for each electrolyte until the desired level is reached and when it is desired to
draw off either electrolyte it can readily be done by opening the tap on the outlet
pipe leading from the cells from which the electrolyte is to be withdrawn.
And in order that this Invention may be well understood we will describe with
reference to the accompanying drawing a battery provided with an arrangement
according to this Invention.
Figure 1 is a longitudinal section of so much of a battery as is necessary to
illustrate this Invention.
Figure 2 is a transverse section on the line 1-2 Figure 1, and
Figure 3 is a plan shewing the connections at top.
A is the vessel or casing in which the cells are formed, it being divided into the
cells by the non-porous partitions b and porous partitions c consisting of plates of any
suitable material usually used for the purpose and let into grooves in the sides and
bottom of the casing. The cells d which are to contain one of the electrolytes all
communicate by means of the holes e, with a longitudinal passage f common to them
all and formed in the substance of the bottom of the vessel A and having at its one
end a vertical pipe or other inlet by which the electrolyte can be introduced. For
instance the electrolyte may be introduced into the first cell of the series and thence
flow into the other cells by the passage and holes e. h is a piece provided with a
gauge glass i for indicating the quantity of electrolyte in the cells and with an outlet
tap j. The cells which are to contain the other electrolyte communicate by means
of the holes with a longitudinal passage m common to them all and also formed in
the substance of the bottom of the vessel A and provided with a gauge glass p and
outlet tap and means for introducing the electrolyte as aforesaid. Z are the zincs
and C the carbons and W are the wires by which they are connected up.
The one electrolyte is introduced as aforesaid and passes along the passage of (the
tap being closed) and up by the holes e into the cells d, and the other electrolyte is
introduced as aforesaid and passes along the passage m (the tap 9 being closed) and
by the holes into the cells k. When it is desired to draw off the electrolytes or
either of them, this can be done by opening the taps j org or both.
The holes or passages may be coated internally with marine glue or other acid
proof coating or be lined with a protective material such as ebonite.
If so desired, the cells of several batteries can be made to communicate by means
of passages or pipes forming continuations of the passages fand m from battery to
battery so that the cells of all the batteries can be filled with or emptied of the
respective electrolytes simultaneously. If so desired, the communications with the
cells for the passage of the electrolytes may be made by means of tubes instead of by
passages or holes formed in the substance of the vessel A.
Having now particularly described and ascertained the nature of our said Inven-
'ion and in what manner the same is to be performed we declare that what
we claim is :-
First. In electric batteries working with two liquids or electrolytes pipes or passages

page_text: forming communications with the respective cells in such manner that the said cells
can be filled with or emptied of the respective electrolytes by one operation substantially
as hereinbefore described.
Second. The arrangement and combination of parts forming a two liquid battery as
hereinbefore described and illustrated by the accompanying drawings.
