Manufacture of Lead for the same.
THOMAS WILLIAM BUSH F.R.A.S. Steward Willey Old Hall, Broseley,
Shropshire MATTHEW DOUBLEDAY, Builder's Merchant Loughboro' Road
West Bridgford, and Carrington Street Bridge Nottingham do hereby declare
the nature of this invention to be as follows
The elements are made with spongy, granulated, and honey combed lead, or
shot, and which we hereafter call hydrolized lead. We also, for the purpose of
this Specification, apply the term
as a short title for "hydrolized lead
cells." We manufacture hydrolized lead by a process for which we claim protection
in this Patent.
"cells
"
This process consists in pouring molten lead into water or any other fluid at
suitable temperatures necessary for the particular purpose of producing the several
forms mentioned above.
Our cells may be arranged in various ways. One element may consist of any of
the aforesaid preparations of lead contained in a porous pot, which is placed within
another vessel and then surrounded by the same or any other of the aforesaid pre-
parations of lead for the other element. Another method is to divide any vessel
of suitable form into compartments, by nonconducting porous divisions, filling each
compartment with our preparation of lead. Circular vessels may be used when
convenient, and the elements arranged concentrically.
We also claim to make use of our hydrolized lead for the construction of
cells of large dimensions for the purpose of storing and furnishing electrical energy,
for private and public uses of an extensive character.
We claim the exclusive use of porous earthenware, cocoa nut fabric, cocoa nut
fibre prepared with plaster of paris or other suitable material, asbestos, and alag
wool, for separators in our cells.
We also claim to make cells with our hydrolized lead in the following manner,
by forming it into plates with cocoa nut fabric, or other suitable material. The
plates to be insulated and bound together by wooden screw bolts & nuts.
We claim the exclusive use of wooden screw bolts and nuts for all similar
purposes.
We also claim to fill in the meshes of accumulator grids of any form and make
with our hydrolized lead, instead of the lead salts commonly used.
Our cells are prepared by the usual Planté process, but they may also be
prepared by making use of lead salts in combination with hydrolized lead and
prepared in the usual manner.
We claim for our cells, relatively, a very great increase of active surface,
and, consequently a proportionate increase in their capacity for the storage
of electrical energy, and decrease of electrical resistance. Also freedom from
liability to get out of order, simplicity of construction, and cheapness of
production.

page_text: West Bridgford and Carrington Street Bridge Nottingham. We 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:—
The elements are made with spongy, granulated, or honey combed lead, and
shot, and which we hereinafter call "hydrolized lead." We also for the purpose
of this Specification apply the term "cells" as a short title for hydrolized lead
cells. We manufacture hydrolized lead by a process for which we claim protection
in this Patent.
1. This process consists in pouring molten lead into water, or acid diluted
with water, or an alkali diluted with water minimum strength 1.200 maximum
anything.
2. Our cells admit of numerous arrangements. We may make use of a porous
vessel filled with hydrolized lead, placing the same within a larger vessel capable of
holding a suitable electrolite and leaving a sufficient space, also filled with hydro-
lized lead, the elements being kept from contact by the porous vessel. Another
method is to divide any vessel of suitable form into compartments by porous
divisions, filling each compartment with our preparation of lead arranged as a
couple.
Circular vessels may be used and the elements arranged concentrically.
Another method is to cast our lead directly upon grids or into moulds placed in
water, or water made acid or alkaline-and in each case reduced by pressure into
uniform thickness and coherence.
We also claim protection for plates made in the following manner-that is-
cocoa nut matting or fibre laid in water, or water prepared as before, and cast
upon it on one or both sides hydrolized lead which is afterwards pressed into
an uniform thickness. We claim the exclusive use of cocoa nut matting or
cocoa nut fibre prepared with plaster of paris for separators, the plaster being
mixed with water and run into the interstices of the matting or fibre in a liquid
state.
We claim the exclusive use of wood or vulcanite screw bolts and nuts used for
binding plates together so forming cells without binding frames which is done in
the following manner-The plates having four or more holes drilled in them and
then put together with our separators or some of the many separators now in use,
the bolts passed through the holes and then tightened up with the nuts.
We prepare our cells by the usual "Planté" process but when we use hydro-
lized lead in combination with lead salts they are charged in the ordinary direct
manner.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. The manufacture of hydrolized lead by the processes named, and its application
to electrical purposes generally.
2. The construction of electrical or storage cells, also the manner of insulating
and binding together with screw bolts and nuts as herebefore described.
3. Facilitating the construction of elements of much larger dimensions than
Liahnuta made
