PROVISIONAL SPECIFICATION.
Improvements in or connected with Cells for Electric Batteries.
I, HENRY COWARD WARTH EMERY, of 61 Gloucester Place, Portman Square,
in the County of London, Brewer's Collector, do hereby declare the nature of this
invention to be as follows:-
My invention refers to cells or containers for electric batteries, whereby, when the
cell or battery is not requried for use, its position can be changed, and the excitaut
thereby automatically removed from the electrodes.
According to my invention, I make the cell oblong or rectangular in shape, or
longer than it is broad, with the electrodes arranged at one end thereof, and for
this purpose they are inserted in an aperture, and when so inserted they are tightly
wedged up in same, whereby they cannot move therein, and when the cell stands in
an upright position they are always vertical and parallel with the end of the said
cell. The excitant placed in the cell about half-way up, so that when the cell is
standing, the zincs and carbons are in the fluid and the battery works, but when it
is not required for use, the cell is turned over on its edge; the liquid then drops
below the electrodes, which are thus free of the excitant fluid, and so remain, and
the cell is kept in this position until it is again required for use; the electrodes
being so placed that they always remain parallel with the end of the cell, and are
80 arranged that the liquid freely runs off from same when the cell is out of action.
The shape of the cell of course may vary, but the object of having one end narrow
is to provide a shoulder that will hold the electrodes in position. The electrode end
of the cell is or may be fitted with a cap surrounding the terminals or nozzle through
which the electrodes are passed.

COMPLETE SPECIFICATION.
Improvements in or connected with Cells for Electric Batteries.
I, HENRY COWARD WARTH EMERY, of 61 Gloucester Place, Portman Square,
in the County of London, Brewers Collector 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 refers to cells or containers for electric batteries constructed and
arranged as hereafter described, whereby when the cell or battery is not required
for use, its position can be changed and the excitant fluid thereby automatically
removed from the electrodes.
According to my invention I make the cell oblong, rectangular, or of a like shape
(longer than it is broad) and arrange the electrodes at one end thereof, they being
inserted in an aperture and tightly or securely fixed therein, so that whatever the
position of the cell may be, the electrodes are always parallel with the side or end
of the said cell.
In order to more fully describe my invention I will refer to the accompanying
sheet of drawings on which similar letters of reference refer to like parts in the

page_text: Figure 1 is a side elevation of a cell of an electric battery constructed and
arranged according to my said invention, and Figure 2 is an end sectional elevation
of same.
Figure 3 is a side elevation of the same or a similar cell when thrown out of
action by change of position,
'
Figure 4 being an end view of Figure 3, that is, when the cell is in the position
indicated at Figure 3, Figure 4 thus showing what would be the top of the cell
when placed in operative position, and
Figure 5 is a perspective view.
A is the cell, BC are the electrodes arranged at one end thereof, D is the
aperture or neck into which the electrodes BC are inserted, being securely held or
fixed by wedges, a cover or cap, or by other means, and provided with terminal
fixtures E F; the electrodes are so arranged that the broadest sides of same stand
at right angles to the end of the cell.
So much excitant fluid is placed in the cell, as to about half fill same, or so
that when the cell is standing vertically as at Figs. 1, 2, and 5, the zincs and
carbons or other electrodes are in the fluid or fluids and the battery is in action.
When however the battery is not required for use, it is only necessary to turn the
cell into the position shown at Figs. 3 and 4, when the liquid will drop below the
electrodes, and the electrodes being thus freed from the exciting fluid, remain inactive
until the cell is again placed in an upright position, as at Figure 1.
The shape of the cell may of course vary, thus although I have shown the cell
(Figure 1) to be of oblong shape when viewed in horizontal section, and I have
stated such may be rectangular, yet other shapes may be employed as would afford
the necessary space for the liquid when turned over, thus, for example, the cells
might be trapezoidal in plan; also in many cases I introduce a shoulder or web G
as shown at Figure 3 and by dotted lines at Figure 4, this shoulder division or
web G extending entirely across the cell from the top to comparatively near the
bottom and preventing the fluid being rocked or washed against the opening or
mouth of the cell, by reason of say any shaking action to which the batteries
may be subjected or such as might possibly be caused by carelessness in turning
the cells.
I do not limit myself to the particular formation of the aperture or neck
through which the electrodes are passed, as the upwardly projecting collar D
shown at Figures 1 to 4 may be higher or lower as desired, or may be square as
there shown, or circular as at Figure 5, or even the cell (especially when formed
with the shoulder or web G) may be made without any such projecting rim or
neck. It will be understood that with cells constructed according to my invention
it is of considerable advantage that the electrodes should be so held therein in such
position that the liquid will freely run off the same when the cell is thrown out of
action.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim as my improvements in or connected with cells for electric batteries is as
follows:-
1. A cell of oblong, rectangular, trapezoidal or the like shape in plan, and
having electrodes inserted through an aperture or mouth formed at one end of such
a cell, and securely fixed in position, whereby when the battery is not required for
use, its position can be changed and the excitant fluid thereby removed from the
electrodes, substantially as set forth.
2. A cell of oblong, rectangular, trapezoidal or like shape in plan, a top
aperture or mouth formed at one end of such a cell, and electrodes inserted through
such aperture and securely fixed therein, in combination with a shoulder or web
dividing the upper part of the cell, but not extending to the bottom thereof, whereby
splashing or overflow of the excitant is prevented when the position of the cell is
changed for throwing the battery out of action substantially as set forth.

page_text: 3. The combination of a cell A of the shape shown on the drawings, electrodes BC
having suitable terminals E, aperture or neck D for insertion of said electrodes, and
web or shoulder G, all constructed, arranged and acting substantially as and for the
purposes hereinbefore described with reference to the accompanying drawings,
together with any mere modification or modifications thereof.
Dated this 27th day of January 1894.
