PROVISIONAL SPECIFICATION.
Improvements in Secondary Batteries.
MARK BAILEY Hollies Lodge Clarence Road Wood Green London N. Electrician
and JOHN WARNER 21 Osborn Street Whitechapel London E. Ironfounder do hereby
declare the nature of this invention to be as follows:-
Our invention consists in causing the active plates to form the dividing walls of
the cell or cells. We provide an outer box or containing chamber of wood, glass,
earthenware or other suitable insulating material or the box may be formed of metal
suitably lined with an insulating substance. The sides of the outer box or chamber
may be quite plain or grooves may be formed therein. The active plates which may
be of lead or any other suitable metal are forced into the grooves and secured by
marine glue or any similar material unacted upon by acid or they may be forced
against an internal lining of rubber or equivalent. In batteries constructed as
described one and the same plate is positive in one cell and negative in the other
contiguons to it.

Improvements in Secondary Batteries.
MARK BAILEY Hollies Lodge Clarence Road Wood Green London N. Electrician
and JOHN WARNER 21 O-born Street Whitechapel London E. Ironfounder 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:-
Our invention consists in causing the active plates to form the dividing walls of the
cell or cells. We provide an outer box, or containing chamber of wood; glass earthen-
ware or other suitable insulating material, or the box may be formed of metal suitably
lined with an insulating substance. The sides of the outer box or chamber may
be quite pain or grooves may be formed therein. The active plates which may be
of lead or any other suitable metal are forced into the grooves and secured by
marine glue or any similar material unacted upon by acid or they may be forced
against an internal lining of rubber or equivalent. In batteries constructed as
described one and the same plate is positive in one cell and negative in the other
contiguous to it.
To enable the construction and operation of our invention to be better understood
reference is made to the accompanying drawing in which :-
Fig. 1, is a front view of battery plate.
Fig. 2, is a section shewing insulating medium in position between plates.
Fig. 3, is a front view of insulating medium.
Fig. 4, is
position.
a longitudinal section of a battery shewing a series of plates in
Fig. 5, is a plan of case.
Fig. 6, is a plan of case shewing arrangement when insulating medium is omitted.
Fig. 7, is a vertical section of metallic cell baving rubber lining.
In the drawing see fig. 1, 2, 3, 1, is the plate which may consist of plane
sheet lead or any equivalent metal suitable for use as a secondary element. 2, is
an insulating frame which may consist of wood, ebonite glass or other good
insulating material, two or a series of plates having insulating frames between each
of them are mounted up as shewn in fig. 4, and placed in a trough B.
ED

page_text: A solution of sulphuric acid and water or its equivalent if the plates are formed
of any other metal than lead is poured into the space 3, formed by the frame 2,
through the holes or gaps 4, left in the upper part of the frame, terminals 5,
preferably of the same materials as the plate are provided for the first and last
element. Upon passing an electric current through the plates so mounted each
plate of the series depending upon the direction of the current will become positive
on one side and negative on the other. The constructional arrangement shewn in
figs. 1 to 4 is that we prefer to employ when the elements are mounted upon a plain
box B, formed of wood; glass, earthenware or other suitable material as shewn
in fig. 5.
The plates are placed in the box, and pitch or marine glue is run into the spaces 6,
left between the insulating frames and the side walls: Although we have described
the plates as having insulating material between them we can obtain equally good
results by mounting them up in the manner shewn in fig. 6, in which the box, case
or containing chamber B, has grooves 7 formed in it within which the plates are
placed; a coating of marine glue or other suitable cement to run round the edges.
Each plate is prepared so as to have a positive surface on one side and negative
surface on the other; by this we mean that one surface of the plate in the case of a
lead plate consists of lead peroxide while the opposite surface of the same plate
consists of spongy lead or in the case of other elements equivalent electrical positive
and negative conditions exist; the spaces 3, are filled with sulphuric acid and water
and terminals 5, are formed thereon or fitted thereto.
Fig. 7, shews a case or cell formed of thin metal such as sheet iron coated or lined
with rubber 8.
Elements prepared as described may be mounted in metallic rubber lined cases with
insulating frames or without as may be most convenient, the thin rubber lining
replacing the glue or cement.
In all the cases described the active plate forms the dividing wall from cell to cell.
In a former Specification of Letters Patent No. 16,669 of. 1887 we have described
a woven plate part of which is positive to its other part in a contiguous but insulated
cell or containing chamber, the construction of the plate being such as to bind the
cells together without joints. We lay no claim to such a combination in this applica-
tion, our object being to employ plates constructed as described to form the party
walls of the cell; so that although a number may be mounted in a single trough
without insulating partitions, the electromotive force will depend upon the pairs of
plates so mounted.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same. is to be performed we declare that what we
claim is―
1st. In secondary batteries the application and employment of the active lead or
other plates or elements in such a manner as to form the dividing wall of the cell or
cells and so that one side of one and the same plate is electrically positive to the other
as set forth.
2nd. In a secondary battery the particular combination, method of fixing, and
arrangement of elements as described with reference to fig. 5.
3rd. In a secondary battery the employment of plain lead plates, mounted up
without insulating material between them, and prepared so that one part of one and
the same lead plate consists of spongy lead and the other part of lead peroxide,
substantially as shewn and described under fig. 6.
4th. The combination and use in or with metallic battery cells lined with rubber
or equivalent of lead plates prepared as described.
