An Improved Method of Manufacturing Woven Plates for Secondary
Batteries.
MARK BAILEY of Holly 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 an improved method of manufacturing woven plates for
portable and other forms of secondary batteries, whereby we obtain great flexibility
in the plate and overcome any tendency to bulge and decrepitate while being formed,
or after a longer or shorter period of use.
We prepare a network preferably of lead or other suitable wire, ribbon or strips,
and having a selvage at the edge; two, three, or any suitable number of such
wires, threads, or ribbons, are interwoven preferably in the longitudinal direction
of the plate with one, two, three, or more threads of cotton twine, silica cotton or
spun asbestos fibre, so that each metal wire or wires, threads or ribbons, is separatea
thereby.
The mesh or network, constructed as described can be manufactured or woven in
any length, and of any width, or of any size or gauge of wire, and cotton, twine,
silica fibre, or other separating material.
We find that when plates constructed as described are formed upon the directions
laid down by Planté for preparing secondary battery plates, that they retain their
shape, and are free from bulging or decrepitation.
By our improved method of manufacture, secondary battery plates constructed as
described can be formed in any length, and after forming can be cut to the required
dimensions.
These plates are also especially suitable for mounting up in the cell after the
manner described in our application for Letters Patent No. 16,669 December 3rd
1887.

An Improved Method of Manufacturing Woven Plates for Secondary
Batteries.
MARK BAILEY of 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 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 an improved method of manufacturing woven plates for
portable and other forms of secondary batteries, whereby we obtain great flexibility
in the plate, and overcome any tendency to bulge and decrepitate while being formed,
or after a longer or shorter period of use.
We prepare a network preferably of lead or other suitable wire, ribbon or strips,
and having a selvage at the edge; two, three, or any suitable number of such wires,
threads, or ribbons, are interwoven preferably in the longitudinal direction of the
plate, with one, two, three, or more threads of cotton, twine, silica cotton, or spun
asbestos fibre, so that each metal wire or wires, threads or ribbons, is separated
thereby.
The mesh or network, constructed as described can be manufactured or woven in
any length, and of any width, or of any size or gauge of wire, and cotton, twine,
silica fibre, or other separating material.
We find that when plates constructed as described are formed upon the directions
laid down by Planté for preparing secondary battery plates, that they retain their
shape, and are free from bulging or decrepitation.
By our improved method of manufacture, secondary battery plates constructed as
described can be formed in any length, and after forming can be cut to the required
dimensions.
These plates are also especially suitable for mounting up in the cell after the
manner described in our application for Letters Patent No. 16,669 December 3rd
1887.
To enable our Invention to be better understood we will now describe the same
more fully by means of the accompanying drawing; in which similar letters of
reference refer to similar parts in each figure.
In the net work therein shewn at Figs. 1 & 2 A, is a thick wire of lead or other
suitable metal, which we prefer to wind as shewn. In a direction preferably at right
angles to A, we interweave two, three or any suitable number of threads or strands of
cotton, twine, silica cotton, spun asbestos fibre B, with a greater or less number of
smaller lead or other suitable wires C, these being again crossed at right angles by
smaller wires D, of lead or other suitable metal the edges being formed in a selvage E,
as shewn. If desired ribbons, or strips of lead or other suitable metal may replace
the wires Fig. 3, and the strands of cotton, twine, or other fibrous material may be

page_text: stiffened by immersion in pitch, shellac, varnish, or other equivalent material unacted
upon by acid. The plates constructed as described, are now formed upon the Planté
system.
By our before described improved method of constructing secondary battery plates
we are enabled to produce such, of any size or gauge of wire, and of any required
area. After forming upon Planté's method they can be cut to any length, as see edge
fig. 1.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we would wish it understood
that we lay no claim to any method of preparing the flexible plates before formation
by added material of any description, but only upon the system described by Planté,
we claim
1st. The particular method of constructing flexible plates, and the use thereof
when formed on the Planté system, for secondary batteries, substantially as herein
shewn.
2nd. The combination in a flexible battery plate of two, three, or any suitable
number of lead or other suitable wires, ribbons or strips interwoven with two, three
or any other suitable number of threads of cotton, twine, silica cotton, spun asbestos
fibre, or equivalent good insulating substance, so that each metal wire, ribbon, or
strip is separated, or partly separated thereby the whole being formed into a web
or mesh having a selvage as set forth.
