CERTAIN IMPROVEMENTS THE CONSTRUCTION OF ELECTRICAL BATTERIES
Year: 1885

page_text: I JAMES TARCOTTON ARMSTRONG of Albion Street, Hanley, in the County of
Stafford, Analytical and Consulting Chemist, do hereby declare the nature of my
invention for "CERTAIN IMPROVEMENTS THE CONSTRUCTION OF ELECTRICAL
BATTERIES" to be as follows:-
IN
My invention has for its object the improvement of Electric Batteries, whereby
they are more easily made or put together and the first cost is considerably
effected.
In the present manner of construction the outer vessel of the Battery is made
round like a jar or a big outer vessel of a square shape is constructed which has
placed inside it one or more porous pots, or, has ribs put in it into which porous
plates are slipped, which outer vessels if made of wood and covered over are
difficult to make tight and are costly and if made of any other matterial are costly
and not handy for carriage, very unsuitable for transit and take much time to
construct.
Now I get over this by making the outer part of the Battery (that is the part
now understood as the box or chamber part) in sections with flanges and then
joining the said sections together with screws and nuts or in any other suitable
manner and these sections having flanges I make of ebonite, earthenware, glass,
insulated wood or other suitable matterial, but I prefer so far earthenware or glazed
china. The joints I make tight with asbestus putty, rubber or other substance
that may be found to answer the purpose of making a tight and lasting joint.
In this way I am able to fit up a Battery with one or more porous plates or if
necessiary cells and with the other parts, and my outside vessel sections in a much
quicker and more sattesfactory manner.
The plates I would place between the flanges and having holes through them at.
or near the edges, would pass the bolts that fasten the two Hanges together through
these, (or in any manner as may be found to answer) & screw all up, and if cells
simply place them inside after the outer part was screwed together.
These sections can be made in any size or shape and with or without ends as
may be found best & requisate,

I JAMES TARBOTTON ARMSTRONG of 9 Albion Street Hanley in the County of
. Stafford, Analytical and consulting Chemist, do hereby declare the nature of my
invention for "CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF ELECTRICAL
BATTERIES" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
My Invention has for its object to facilitate the construction and transport of
electrical batteries and to reduce their cost especially when they are inade of large
dimensions.
In electrical batteries as usually made, the outer vessel is either cylindrical like
a jar or it forms a rectangular trough provided with inside ribs for holding the
porous plates in position. Such troughs are unsuitable for transport. If made of
wood and covered over, it is difficult to keep them tight, if made of other material
they are usually expensive.
To avoid these drawbacks I construct the outer part or trough of the battery of
independent sections and hold them together by means of screw bolts or equivalent
appliances.
In further describing my Invention reference will be made to the accompanying
drawing in which Figure 1 is a sectional perspective of a battery built up of three
sections A. B. C; and, Figure 2 a horizontal section, and serving to illustrate my
principle of construction." These sections may be made of earthenware, glass,
insulated wood or other suitable material.
These sections above mentioned, which may be of rectangular or any other
convenient shape, are separated from one another by porous plates D, E, and
provided with flanges a, b, c, d held together by means of bolts or equivalent
devices, the joints being made tight by means of Asbestos putty, Rubber,
Chadderton's Compound, or like suitable material. The bolts may either pass
through the porous plates, as well as through the flanges, as illustrated by the
drawing; or outside the porous plate; and one bolt may pass through one or more
pairs of flanges so as to connect two or more sections, and, if the plates are not put
between the flanges, two sections only may be used instead of three.
Each Compartment or cell of the battery is preferably closed on all sides, except
that the top has a slot d', or slots, for the insertion of the zinc or other electrode,
and that suitable openings are provided for the inlet and outlet of the exciting
liquid.
Although I prefer to insert the porous plates between the flanges of adjoining
sections, this is not necessarily the case, as each section may have a porous plate
attached to it independently of the flanges.
The Sections herein referred to and described can be made in any size or shape
and with or without end and middle pieces as may be found best and requisite,

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
An electrical battery having an outer vessel or trough built up of several
independent sections connected with one another, substantially as and for the
purposes herein described.
