MENTS IN VOLTAIC BATTERIES
Year: 1882

page_text: " IMPROVE-
LETTERS PATENT to Alfred Rosling Bennett, of Glasgow, in the County of
Lanark, North Britain, Telegraph Engineer, for an Invention of
MENTS IN VOLTAIC BATTERIES."
PROVISIONAL SPECIFICATION left by the said Alfred Rosling Bennett at
the Office of the Commissioners of Patents on the 21st January 1882.
ALFRED ROSLING BENNETT, of Glasgow, in the County of Lanark, North
Britain, Telegraph Engineer. "IMPROVEMENTS IN VOLTAIC BATTERIES."
This invention, has for its object the production of a cheap and effective single-
fluid voltaic battery.
To form the negative portion of the battery, I place an electrode of iron or steel
packed tightly in small fragments of the same metal, such as iron or steel turnings
or borings, or clippings of iron or steel wire, in a solution of potassium monoxide,
potassium hydroxide, sodium monoxide or sodium hydroxide.
To form the positive portion of the battery, which should be separated from the
negative by a porous cell or diaphragm, I use the same solution, immersing in it an
electrode of zinc, the shape of which is immaterial.
The electrode of iron or steel may be in the form of a plate, rod, wire or
cylinder, or the vessel in which the battery is contained may be of iron or steel
and form the electrode.
For the electrode and fragments of iron or steel may be substituted an electrode
and fragments of gold, silver, platinum, nickel or cobalt.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed.
by the said Alfred Rosling Bennett in the Great Seal Patent Office on the
20th July 1882.

"IMPROVEMENTS IN VOLTAIC BATTERIES."
This Invention has for its object the production of a cheap and effective single
fluid Voltaic Battery.

or borings or clippings of iron or steel wire, in a solution of Potassium Monoxide,
Potassium Hydroxide, Sodium Monoxide, or Sodium Hydroxide.

The electrode of iron or steel may be in the form of a plate, rod, wire, or cylinder,
or the vessel in which the battery is contained may be of iron or steel and form the
electrode.
For the electrode and fragments of iron or steel may be substituted an electrode,
and fragments of gold, silver, platinum, nickel or cobalt.
And in order that my said Invention may be properly understood I now proceed
more particularly to set forth the system mode or manner in or under which the
same is or may be used or practically carried into effect, reference being had to the
accompanying drawings and to the letters and Figures marked thereon, that is
to say:-
Figure 1, represents an elevation of a single cell battery constructed and
charged according to my present invention.
Figure 2, represents a section of the same.
The containing vessel B, I form of iron or steel and use the same as the negative
electrode of the battery by connecting the terminal and wire A, directly with the
vessel B, which is packed tightly with the small fragments F, of the same metal
in a solution of Potassium Monoxide, Potassium Hydroxide, Sodium Monoxide, or
Sodium Hydroxide.
For the positive portion of the battery I place the porous cell D, into the herein-
before mentioned metal fragments F, and solution mixed therewith, I then charge
the cell D, with a similar solution immersing in it an electrode of Zinc E,
supported in any suitable manner and metallically connected with the terminal
and wire C.
Having now described and particularly ascertained the nature of my said
invention, and a system, mode, or manner in or under which the same is or
may be used, or practically carried into effect, I would observe in conclusion that
I do not limit myself to the precise form or mode of construction of battery shewn
in the annexed drawings, for the reason which will be obvious to an Electrician that
the form or construction may be varied without departure from the essence of my
Invention but what I consider to be novel and original and therefore claim as
the Invention secured to me by the hereinbefore in part recited Letters Patent
is:-
The Voltaic batteries constructed and charged substantially as herein before
described.
In witness whereof I the said Alfred Rosling Bennett have hereunto set my
hand and seal this Eighteenth day of July in the year of our Lord One
thousand, eight hundred and eighty two.
ALFRED ROSLING BENNETT (L.S.)
