RICHARD PHILIP MILBURN of 52 Percy Street Newcastle upon Tyne Professor
of Music and Chemistry do hereby declare the nature of this invention to be as
follows:-
My Invention consists of a battery for the purpose of lighting by electricity, houses
public buildings vehicles of every description including railway carriages miners
safety lamps and for any purpose where light is required. The form of the battery
The
may be of any suitable shape suitable for the purpose for which it is intended.
following is convenient for carriages and other purposes. The box or shell to contain
the batteries may be divided by a partition in the middle and having subdivisions at
right angles thereto. This box may be of wood vulcanite metal earthenware or other
suitable material. For small work the compartments may be covered or lined with
india rubber or other suitable substance and shall not require any earthenwaro jar or
other jar except the porous within it for the cell or battery.
The battery consists of an earthenware jar or jar of other suitable substance con-
taining one liquid hereafter described. There is a porous cell within containing
another liquid. The outer cell receives a zinc plate the inner receives a carbon and
giving as near as possible the same surface measurement as the zinc.
At the same
time I reserve to myself the right of making the outer cell of porous material carbon
for instance and reverse the carbon and zinc as well as the liquids. The miners lamp
may be made in this way thereby saving the weight of an earthenware jar having the
outer cell of carbon which may be glazed or it may be of metal or other suitable
material whilst the inner jar is of porous clay or other suitable material.
The following are the charging or exciting liquids.
Bicromate of Potash Solution Sulphuric Acid and in adition Sulphide of Zinc if
preferred, for the Zinc plate.
Bicromate of Potash Solution and Nitric Acid on the Carbon or Nitric Acid only.
I claim for this battery from the solutions used and the arrangement and compo-
sition of the jars great economy of cost, duration of light combined with steadiness
and simplicity over all previous portable electrical light batteries.

page_text: 1, RICHARD PHILIP MILBURN of 52 Percy Street Newcastle upon Tyne Professo
of Music and Chemistry 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 :-
My invention consists of a battery for the purpose of lighting.by electricity houses,
public buildings, vehicles of every description including railway carriages, miners
safety lamps and for any purpose where light is required. The form of the battery
may be of any suitable shape, suitable for the purpose for which it is intended. The
following is convenient for carriages and other similar purposes. The box or shell to
contain the batteries may be divided by a partition in the middle and having sub-
divisions in the opposite direction. This box may be of wood vulcanite, metal
earthenware or other suitable materials. For small work the compartment may be
covered or lined with India rubber or other suitable material and shall not require
any earthenware jar or other jar except the porous jar within for the cell or
battery.
The battery consists of an earthenware jar or jar of other suitable substance con-
taining one liquid hereafter described. There is a porous cell within containing
another liquid. The outer cell requires a zinc plate the inner receives a carbon and
giving as near as possible the same surface measurement as the zinc. At the same
time I reserve to myself the right of making the outer cell of porous material carbon
for instance and reverse the carbon and zine as well as the liquids. The miners lamp
may be made in the way thereby saving the weight of an earthenware jar having
the outer cell of carbon which may be glazed or it may be of metal or other suitable
material whilst the inner jar is of porous clay or other suitable material.
The following are the charging or exciting liquids.
Bicromate of Potash Solution Sulphuric acid and water on the Zinc side.
Bichromate of Potash Solution and Nitric Acid on the Carbon Side, or Nitric Acid
only.
The Solutions used and the arrangement and composition of the jars or cells, effect
great enconomy in cost, & in weight of parts; the battery thus producing greater
duration of light & steadiness, than previous portable Electric light batteries, as well
as being lighter in weight, simpler, & less costly.
Thus a miners lamp of about 3 lbs. weight will give a steady light of about
2 candles for 16 hours. approximately, when the liquids are used with the proper
proportions of about 2 parts Bichromate of Potash KO, Cr O2 + 30 parts H₂ 0, +
6 parts Sulphuric Acid H, SO4, which acts on the Zinc Plate; & about 2 parts of

page_text: Nitric Acid HNO, which acts on the Carbon in the porous or inner cell. The
preparation of the Bichromate Solution is as follows. The Bichromate of Potash
dissolved in the water which should be boiling, & when cold, the Sulphuric Acid
added.
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,
1st. The use in a battery of Bichromate of Potash, Sulphuric Acid, and Water in
combination & sufficiently amalgamated, on the one Pole, and Nitric Acid at the other
Pole.
2nd. The whole arrangement of battery as hereinbefore described.
3rd. The whole arrangement of battery as herein before described in conjunction
with the liquids used.
