PROVISIONAL SPECIFICATION.
Improvements in Secondary Battery Plates, Grids and the like.
We, WILLIAM ALFRED GENT, 23, Ivy Lane, Brockley, London, S.E., Engineer,
and SAMUEL JEVONS, of Escote Hall, Hampton-in-Arden, Warwickshire, Gentle-
man, do hereby declare the nature of this invention to be as follows:-
This invention consists of an improved form of plate or grid and the like for
secondary batteries and is so designed to firmly support or hold the active material
and retain it in close contact with the conducting plate. The plate or grid are
constructed of a required number of ribs running parallel to each other from the
outer or boundary ridge of the required sized plate to the opposite boundary
ridge. These ribs have strips of any required width or shape connecting from
or joining from the top of one rib to the bottom of the next rib and the adjoin-
ing one from the bottom of the rib to the top of the next rib and so on through-
out making an interwoven plate or grid, a space being left of any required width
between each strip from rib to rib. The mould or chill is made to cast the
plate or grid as described in the foregoing in one body each strip or rib or ridge
joining in its own sectional area the part connecting thereto.
Dated this 7th day of April 1899.

Improvements in Secondary Battery Plates, Grids and the like.
WILLIAM ALFRED GENT, 23, Ivy Lane, Brockley, S.E., Electrical Engineer, and
SAMUEL JEVONS, Escote Hall, Hampton-in-Arden, Warwickshire, do hereby
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:
My invention consists of an improved form of plate or grid and the like for
secondary batteries and is so designed to firmly support or hold the active
material and retain it in close contact with the conducting plate.
I construct the plate or grid of a required number of ribs running parallel
to each other from the outer or boundary ridge of the required sized plate to the
opposite boundary ridge. These ribs have strips of any required width or shape
connecting from or joining from the tops of one rib to the bottom of the next
rib and the adjoining one from the bottom of the rib to the top of the next rib
and so on throughout, making an interwoven plate or grid, a space being left
of any required width between each strip from rib to rib.

page_text: The mould or chill is made to cast the plate or grid as described in the fore-
going in one body each strip or rib or ridge joining in its own sectional area
the part connecting thereto.
For the purposes of illustration. I will now refer to the annexed drawings in
which:
د:
Figure 1 is a view of a plate or grid constructed according to my invention.
Figure 2 section through: line XY in Figure 1
The plate is formed of any suitable material such as lead which is cast in a
mould: a are what I term the ribs which are continuous and formed integrally
with the strips b arranged as shown, so as to produce what might be termed
lattice work, and this will terminate, passing upon one side and the opposite
side of the next rib, and so on, producing the plate which is well adapted to carry
the composition or paste, and at the same time give sufficient support for the
purpose of preventing the falling or breaking away of the composition. The
relative distance between the ribs and the strips may be varied as required and
this will be a matter which will depend upon the mould, seeing that the essential
feature of my invention consists in the production of the plate or grid of which
the ribs and strips are integral with each other or what may be termed
homogeneous.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A plate or grid for secondary batteries substantially as described and illus-
trated herein and for the purpose set forth.
2. A plate or grid for secondary batteries consisting of ribs and strips in-
tegrally formed together and so arranged as to form what may be termed lattice
work for the purpose of supporting the composition or paste employed, substan-
tially as described and illustrated herein and for the purpose set forth.
