PROVISIONAL SPECIFICATION.
An Improved Form of Galvanic Cell for Bell Ringing and other
Purposes.
1 GEORGE HENRY BAYS, the younger of No. 21 Saint John's Wakefield in the
County of York, Electrician, do hereby declare the nature of my invention for
AN IMPROVED FORM OF GALVANIC CELL FOR BELL RINGING AND OTHER PURPOSES
to be as follows:-
The Electrodes are, a rod or plate of zinc, the surface of which is amalgamated
with Mercury, and broken gas retort carbon, with or without the addition of oxide of
Manganese, or other solid depolariser. The liquid is dilute Sulphuric Acid or other
Acid or Alkali, other than Chloride of Ammonium.
I arrange the broken carbon around the outside of a porous jar, of earthenware,
or other material, and inside a jar of stoneware, or other non-porous material. I
place the amalgamated zine rod or plate in the porous jar, and it is held in the centre
thereof by a copper wire which is fastened to one end of the zine rod or plate, and
passes through the centre of a cover composed of wood, ebonite or other insulating
material, and fitting on the top of the porous jar. This wire forms the negative pole
of the Cell.
A Carbon rod passes down through the broken carbon, and acts as a conductor-a
screw being fastened to the upper end thereof, forms the positive pole of the Cell.
The space between the top of the porous jar, and the outer jar, is sealed with a
compound of pitch, and resin, or other similar substance, a hole being left for the
admission of air.

An Improved Form of Galvanic Cell for Bell Ringing and other
Purposes.
I GEORGE HENRY BAYS, junior of No. 21 Saint John's Wakefield, Electrician, 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 Electrodes are (1) a rod or plate of zinc, the surface of which is amalgamated
with mercury; and (2) broken gas retort carbon, with or without the addition of
oxide of manganese or other solid depolarizer.
I arrange the broken carbon between the outside of a porous jar of earthenware, or
other material, and the inside of a jar of stoneware or other non-porous material.
I place the amalgamated zinc rod or plate in the porous jar, and it is held in the
centre thereof, by a wire preferably of copper, which is fastened to one end of the
zinc rod or plate, and passes through the centre of a cover composed of ebonite,
wood, glass or other insulating material, and fitting on the top of the porous jar.
This wire forms the negative pole of the Cell. The object of this arrangement is to
The cover
get as large a surface of carbon as possible, in proximity to the zinc.
Besides keeping the zine rod or plate in its place, prevents the liquid from evaporating,
and also suppresses any salts that may be formed by the action of the Battery.
A Carbon rod passes down through the broken carbon, and acts as a conductor,
a binding screw being fastened to the upper end thereof, forms the positive pole of
the Cell.
The space between the top of the porous jar and the top of the outer jar, is sealed
with pitch or other similar substance, a hole being left for the admission of air and
for the escape of gasses.
A variety of liquids may be used to excite this Cell, as for instance a solution of
chloride of sodium, or dilute sulphuric acid, or dilute hydrochloric acid.
