Complete Specification Accepted, 17th Aug., 1888
I THEOPHILUS COAD of 10 Thorpe Terrace, Thorpe Road, Forest Gate in the County
of Essex Electrician do hereby declare the nature of this invention to be as
follows:-
This Invention relates to improvements in voltaic or galvanic batteries for electric
lighting, power, or other purposes, and is applicable to double or single fluid
batteries.
The object of this invention is to utilize the full charge of fluid supplied to the cells,
either for intermittant or continuous currents, to prevent local action, and to provide
improved means for connecting the positive and negative electrodes.
In carrying out my invention, for double fluid batteries, I use porous pots with a
suitable portion glazed, or otherwise treated to prevent percolation, and endesmose and
exosmose when not in action, the carbon plates or electrodes are permanently sealed
into the porous pots, leaving an orifice for charging and discharging which can be
securely stopperd, the carbon electrodes are preferably fitted with inettalic contact
pieces.
«
I seal or otherwise fix in the partitions of the cells or compartments which contain
the exciting solution,-porous pots, and zinc electrodes, pieces of suitable material
preferably" platinum, the carbon electrode being on one side of said partition, and
the zinc on the opposite side, the carbon and zinc electrodes are connected and kept in
contact with the pieces of metal fixed in the partitions, by inserting wedges of suitable
shape and material between the porous pots and zinc electrodes, thus enabling them to
be removed without disturbing the connections, and it also prevents the exciting
fluid from flowing into the adjoining cells or compartments when the battery is
reversed.
The top of battery box is provided with a ledge on which rests a piece of suitable
material such as indiarubber, and kept in position by a suitable cover secured by

page_text: The battery being provided with the proper quantity of fluid is set in action in the
usual manner,
but on reversing it, the depolerizing fluid falls into the impervious portion
of the porous pots, and the exciting fluid falls free of the positive electrodes, by which
means the current is interupted or broken and local action prevented.
In single fluid batteries porous pots are dispensed with.
Improvements in Voltaic or Galvanic Batteries.
I THEOPHILUS COAD of 10 Thorpe Terrace Forest Gate, in the county of Essex,
Electrician, 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, firstly; to an improved arrangement for connecting the
positive and negative electrodes of a battery together, being equally applicable to
single or double fluid batteries; and secondly, to an improvement in porous pots for
double fluid batteries..
To enable my invention to be properly understood 1 will proceed to fully describe
the same with aid of the accompanying drawings which show my invention applied to
single and double fluid batteries.

Figure 4 a modification of parts shown in figure 2.
Figure 5 partial sectional side elevation of a double fluid battery.
Figure 6 plan of figure 5.
Figure 7 perspective view of porous pot.
According to the first part, I press the electrodes against contact points by wedges
or spring clips a suitable way of carrying this out is as follows. The cells are
formed together preferably of vulcanite, A, being the outside of a case of cells, and B,
the partitions to divide A, into separate cells. Through each partition near the top I
screw a platinum screw peg C, so that each end slightly projects beyond sides of
partitions B, and press the carbon E, and zinc F, against such projecting points by
means of a wedge D, of vulcanite or other suitable material, by which perfect contact
is obtained, and great facility afforded for the removal of the elements.

page_text: Or in place of the screw peg C, I may use a bent over piece H; and in place of the
wedge D, a clip M, made of vulcanite or other non-conducting material: see figure 4.
At each end of case A, usual terminals G, are arranged for the wires. The cells are
closed by any suitably arranged cover.
Referring to figures 5. 6. and 7. I is the porous pot closed by a top J in which is a
hole J' for filling closed by a cork; the carbon E, within the pot, is formed with a
side arm E¹, projecting through side of pot for contact with pegs C. The zinc F is
made narrower than the carbon and opposed to only a part of latter. Excepting that
part of the porous pot facing the zinc, the rest is glazed or otherwise treated to
prevent percolation and electrical action K, being the glazed part and L, the
unglazed.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed 1 declare that what
I claim is:
1. In voltaic batteries, connecting the electrodes by pressing them against contact
points, substantially as described.
2. In voltaic batteries, the combination of the contact pieces C, or H, suitably held,
and wedges D, or clips M, as and for the purposes described.
3. In voltaic batteries, a porous pot, having a large portion of its surface treated to
prevent percolation and electrical action, as hereinbefore described and illustrated at
figure 7, of the accompanying drawings.
