A New or Improved Mould for Casting Plates or Grids for Secondary
Batteries.
We, WILLIAM ALFRED GENT, 23, Ivy Lane, Brockley, S.E., Electrical Engineer,
SAMUEL JEVONS, Escote Hall, Hampton-in-Arden, Warwickshire, Gentleman, do
hereby declare the nature of this invention to be as follows:-
-
This invention consists of a new or improved mould for casting plates or grids,
for secondary batteries, and is designed for the purpose of casting plates or grids
described in my Specification No. 7321, dated 7th April 1899. I form the mould
in two sections so arranged as to cast or shape the plate or grid after the manner
of lattice work for the purpose of carrying the composition or paste employed
therewith, this lattice plate or grid, supporting the composition at required
intervals, and also providing a continuous plate that is to say the continuity
of the composition is not altogether interrupted in the plate. For the purpose
of illustration, I will now refer to the annexed drawings in which :-
Figure 1, is a view of my mold in its closed position.
Figure 2 view of mould when opened.
Figure 3, cross section through line X-Y in Figure 1.
Figure 4 view of plate or grid.
The mold consists of the plates a & y cut or shaped as shewn in Figure 1,
together with the separating pieces b. The recesses in the plates & &
separating pieces 6 are for the purpose of enabling what I term the ribs d to be
continuously cast, and the strips c are formed in the space f between the plates
&g. The spaces h, shewn in Figure 4 are ensured by the separating strips b.
The two parts of the mould are hinged together at i and any ordinary convenient
pouring arrangement may be employed for the purpose of filling the mold, and
giving the required head of metal, such as at j. By this arrangement it will be
seen, that the plate or grid is so far as metallic contact is concerned continuous,
and the thickness of the separating pieces & plates a & g will determine the
dimensions & distance between the strips c & the plate. Although I have
described this particular form of mould so far as the configuration of the casting
is concerned which is produced therefrom, it will be readily seen that modification's
may be made with regard to shape or configuration without departing from the
principle of my invention.

We, WILLIAM ALFRED GENT, 23, Ivy Lane, Brockley, S.E., Electrical Engineer,

declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention consists of a new or improved mould for casting plates or grids,
for secondary batteries, and is designed for the purpose of casting plates or grids
described in my Specification No. 7321, dated 7th April 1899. We form the mould
in two sections so arranged as to cast or shape the plate or grid after the manner
of lattice work for the purpose of carrying the composition or paste employed
therewith, this lattice plate or grid supporting the composition at required
intervals, and also providing a continuous plate. that is to say the continuity
of the composition is not altogether interrupted in the plate. For the purpose
of illustration, we will now refer to the drawings filed with our Provisional
Specification in which
Figure 1 is a view of our mould in its closed position.
Figure 2 view of mould when opened.
Figure, cross section through line X Y in Figure 1.
Figure 4, view of plate or grid.
The mould consists of the plates a and y cut or shaped as shewn in Figure 1,
together with the separating pieces b. The recesses c in the plates
and and
separating pieces 6 are for the purpose of enabling what we term the ribs & to
be continuously cast, and the strips e are formed in the space f between the
plates a and g The spaces shewn in Figure 4 are ensured by the separating
strips b. The two parts of the mould are hinged together at i and any ordinary
convenient pouring arrangement may be employed for the purpose of filling
the mould, and giving the required head of metal, such as at j.
By this arrangement it will be seen that the plate or grid is so far as metallic
contact is concerned continuous, and the thickness of the separating pieces b
and plates a and g will determine the dimensions and distance between the strips c
and the plate. Although we have described this particular form of mould so
far as the configuration of the casting is concerned which is produced there-
from, it will be readily seen that modifications may be made with regard to shape
or configuration without departing from the principle of our invention.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is-
1. The mould for casting plates or grids, substantially as described and illus-
trated herein and for the purpose set forth.
2. In moulds for casting plates or grids, a series of plates cut or shaped as
shewn, and for the purpose set forth, said plates being separated by separating
pieces cut or shaped as shewn for the purpose set forth, and being hinged or
otherwise connected together so as to form a mould for casting a grid or plate
for secondary batteries as herein described.
3. In moulds for casting plates or grids for secondary batteries the employ-
ment of plates and separating pieces alternately arranged, and adapted to form

page_text: a mould for the purpose of enabling a plate or grid for secondary batteries to be
cast so as to have continuous ribs in the form of lattice work integrally or
homogenously connected together, substantially as described, and illustrated
herein, and for the purpose set forth.
