Accumulators. STORAGE OR SECONDARY BATTERI
Year: 1885

page_text: Accumulators.
I WILLIAM SYMONS Chemist 26 Joy St, Barnstaple Devonshire do hereby
declare the nature of my invention for THE CONSTRUCTION OF STORAGE OR
SECONDARY BATTERIES to be as follows: —
My batteries are made chiefly or entirely of Carbon in plates, rods, or cylinders,
in which cavities or spaces are made for containing Oxide of Lead or other suitable
material. I prefer to use Carbon plates perforated, and so made that when two
are placed together there will be formed an inner chamber or cavity between the
two for the reception of the Oxide. In another form of the battery each plate is
made with internal spaces filled with exide.
For greater security these plates may be supported (and are so in the batteries
I have made) in moveable frames made of wood or other suitable material. The
Carbon plates are placed in vessels or cells containing the necessary liquid with, or
without an arrangement for drawing off the liquid when desireable into another
vessel and easily returning it to the cells when required.
The carbon plates are connected together in proper series either by simple pressure
or gravity or by plates or wires of silver or other conducting material not acted on
by the liquid. To ensure efficient contact, wood or other suitable clamps, springs,
or screws are used, with some elastic nonconducting material intervening where
required. Sometimes I prefer soaking a part or the whole of the Carbon plates in
melted Parrafin, wax or other similar material.

I WILLIAM SYMONS of 26 Joy Street Barnstaple, Devonshire Chemist do hereby
declare the nature of my invention for THE CONSTRUCTION OF STORAGE OR
SECONDARY BATTERIES OR ACCUMULATORS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My batteries are made chiefly or entirely of carbon in plates, rods, cells or
cylinders in which cavities or spaces are made for containing oxide of lead or other
suitable material. I sometimes use perforated plates of carbon so made that when
.two are placed together there will be formed an inner chamber or cavity between
them for the reception of the oxide. In another form of the battery, which I have
also constructed, each plate is made with internal spaces to be filled with oxide..
For greater security the plates or cells may be supported (and are so in the batteries
I have made) in moveable frames of wood or other suitable material.
The carbon plates or cells properly filled with oxide or other suitable material
are placed in vessels or cells containing the necessary liquid, with or without
arrangements for drawing off the liquid when desireable, and easily returning it to
the cells when required.
The carbons are connected together in proper series by simple pressure, or gravity.
One method of doing this is to suspend them on rods, cylinders, or plates of carbon
Another way to make connections is by plates or wires of platinum or other
suitable metal and for this purpose I prefer to einbody in the carbons, in the process
of making, strips or wires of platinum or other difficultly fusible & incorrodible
metal, but I do not confine myself to this process. To ensure efficient contact,
wood or other suitable clamps springs or screws are used, with some elastic material
intervening where required."
Having now particularly described & ascertained the nature. of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is
1st The use of carbon in plates cylinders, cells or rods or any suitable shape, as
receptacles for containing oxide of lead, or other suitable material, so that an
electric current may be produced similar to that produced in storage batteries,
which have hitherto been usually composed of lead.
2nd I claim the method of embodying in the carbons, in the process of making,
strips or wires of platinum or other difficultly fusible and incorrodible metal, as a
means of connecting the plates or cells in proper series, and
3rd I also claim the method of using carbon rods, tubes or plates for uniting in
proper series-the carbons in batteries, but I do not confine myself to either or both
methods of making connections.
Dated twenty third day of November 1885.
