PROVISIONAL SPECIFICATION.
An Oblique Meshed Grid Plate for Storage Batteries.
THOMAS WILLIAM BUSH Stoward Willey Old Hall Willey Park Broseley Shropshire
do hereby declare the nature of this invention to be as follows:-
That it consists in the construction of grids having meshes entering the plate from
each side at any suitable angle downwards and meeting within the plate, thus forming
a longer passage through the grid, thereby increasing the surface of contact between
the plate and the plug, and also minimising the risk of short circuiting through the
plugs working out of the meshes, thus maintaining the storage capacity at its.
maximum by preventing the loss of active material.
I therefore claim for these plates increased capacity for the storage of electrical
energy, a more constant and higher return of the same, and also a longer life. These
grids may be made of lead or other material, and the meshes may be filled with any
substance suitable for the purpose.

COMPLETE SPECIFICATION.
An Oblique Meshed Grid Plate for Storage Batteries.
THOMAS WILLIAM BUSH Willey Old Hall Willey Park Broseley, Shropshire Steward
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
My invention consists in giving speceal forms to the meshes or perforations of Grids
of lead or other suitable material used for supporting the active material in the Grids
or Plates of Electrical Storage Batteries or Accumulators. I construct these in such
a manner that two or more of the opposite walls of each mesh or perforation are
made to enter the Grid obliquely from each surface (downwards by preference when
"in situ "in the cell, but not necessarily so) at any suitable angle and meet each other
respectively in the interior of the Grid. Thus forming, in conjunction with the other
two or more opposite walls of each perforation or mesh a tubular cavity having
parallel walls being discontinuous in its direction through the Grid, and, somewhat,
resembling a stumpy" capital letter V, in its principal section, at right angles to
the surfaces of the saine.
"
I also construct these Grids in such a manner, that in the plane of junction of the
two opposite parts of each of the tubular cavities above mentioned, I introduce a
wall, dividing them into two parts, thus forming a system of oblique "Pocket "
meshes, on each surface of the Grid. This wall or diaphragm, may also be perforated,
to make communication with the adjacent opposite mesh.
By preference, I construct these Grids by casting them between two suitable
mould of cast iron, each mould being capable of being withdrawn from the casting
separately. Each of these mould contains the necessary sets of grooves for the
reception of the metal, the number and position of which are determined, by the
desired transverse section to be given to the tubular cavities through the Grid. When
1 construct Grids, containing the interior wall dividing the perforated meshes, and
forming Pocket meshes, a space is left between the two apposing faces of the mould,
equal to the desired thickness of the dividing wall. These Grids may, however,
be constructed by any other convenient method of which I may apprové, and may
be of any suitable surface area and section, and their meshes may be of any suitable
form and area of section.

page_text: 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.
÷
That when the meshes, of my perforated Grids, are filled with prepared red lead
or other suitable material, such material will form plugs, corresponding to the said
mesbes, and these plugs will be securely locked in the same, in virtue of their
forins, notwithstanding any leability to become loose through compression or waste
arising from usage. I therefore claim for the Grids improvements, relatively, as
follows
1st. Greater durability.
2nd. Greater average capacity for the storage of electrical energy, by the prevention
of loss of active material.
3rd. That they remove the risk of short circuiting, in the cell, by preventing the
plug working out of the meshes, and lodging between the plates.
4th. That, in consequence of the increased length of the perforations, due to their
oblique and discontinuous direction through the Grid, the surfaces in contact with
the active material are increased proportionally, and therefore the capacity of the
Grid, to receive, store, and transmit electrical energy, is increased in the like
proportion.
With reference to the Grids, having divided walls, forming obleque "Pocket"
meshes when these are filled with plugs of prepared redlead or other suitable
material, such plugs will be securely retained in their "Pockets." I claim therefore
as before
1st. Increased durability.
2nd. Increased average capacity.
3rd. Less risk of short circuiting in the cell as afore mentioned.
4th. A very important increase in the active surface of the Grid, due to the
additional area of the dividing wall, and, therfore, a proportionate increase in the
general electrical capacity of the Grid.
I distinctly claim the obleque mesh in all its possible varieties of forum as herein
described for the formation of the perforations, pockets and pockets with perforated
wall in Grids or Plates for Storage Batteries of Accumulators.
