Improvements in or connected with Electric Batteries.
I, JOHN LASKEY DOBELL, of No. 46, Connaught Road, Harlesden, in the County
of Middlesex, Electrician, do hereby declare the nature of this invention to be as.
follows:
-
This invention relates to that class of electric batteries in. which the electrical
energy is obtained by the consumption or combustion of carbon or carbonaceous
matter, and the object of the present invention is to obtain a battery of this class
which will develop greater energy at lower cost than heretofore.
In carrying the invention into effect, a cell or trough of any suitable shape and
preferably formed of iron is employed, and centrally within this cell is arranged
so as to be clear of the bottom thereof a porous pot, and the cell and porous pot are
provided with suitable removeable covers for the purpose of retaining the heat.
Within the trough or cell is placed a suitable quantity of lead which is main-
tained in a molten condition by means of a gas or other suitable fire arranged.
beneath the cell, and within the porous pot is placed a suitable quantity of the
following compound, consisting of the ingredients named combined in or in about
the proportions stated namely:-
Bi-chromate of potash
Chromium tri-oxide
Caustic soda -

In preparing this compound the chromium tri-oxide and caustic soda are first
fused and well mixed together, then the bi-chromate of potash is added whilst the
other ingredients are in a fused state, the whole being thoroughly stirred during the
mixing operation.
The carbonaceous fuel may be fed to the fused lead through feed tubes or in any
other suitable manner.
The fused exciting compound gives up its oxygen through the porous pot to the
molten lead within the cell, which in turn gives it up to the carbonaceous material
with which it combines reducing the same to ash and generating electricity. The
ash may be removed from time to time whilst the oxygen escapes in the form of
carbonic acid.
In order to replace the oxygen taken from the exciting compound in the porous
pot, air or other suitable oxidising agent is forced into the same at the lower
part of the porous pot through a pipe terminating in a perforated ring or the like.
By these means, so long as the battery is fed with fuel, that is to say, with the
carbonaceous material and with an efficient supply of air or other oxidising agent, a
constant current of electricity will be maintained at the expense of such fuel.

may be arranged in any other convenient and suitable way.
By the means hereinbefore described, a powerful primary battery is obtained the
cost of working which is merely nominal, practically the only waste that takes
place being the consumption of carbonaceous material and oxygen the cost of which
is insignificant.

Improvements in or connected with Electric Batteries.
I, JOHN LASKEY DOBELL, of No. 46, Connaught Road, Harlesden, in the County
of Middlesex, 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:-
My said invention relates to that class of electric batteries in which the electric
energy is obtained by the consumption or combustion of carbon or carbonaceous
matter, and the object of the present invention is to obtain a battery of this class
which will develop greater energy at lower cost than heretofore.
And, in order that the said invention may be clearly understood and readily
carried into effect, I will proceed, aided by the accompanying drawing, fully to
describe the same.
In the accompanying drawing which is a vertical section of a battery constructed
according to the present invention, represents a furnace or heating chamber,
which is provided with grate bars a¹, stoking door a² and a flue a³ to carry off the
products of combustion from the fuel, whilst the walls of the chamber are at a*
inwardly flanged for the purpose hereinafter described.
Within the heating chamber or furnace a is arranged a cell or trough of any
suitable shape and preferably formed of iron and this cell or trough is suspended
by means of a flange which rests upon a suitable thickness of insulating
material 6 whilst the top of the cell or pot 6 is enclosed by removeable cover b
held in position by insulated bolts 63 so as to retain the heat.
The cover of the pot 6 is centrally apertured, and within this aperture is
suspended by its flange c¹ a porous pot c in such manner that it is clear of the
bottom of the cell or trough b and the porous pot c is at its upper part closed by
means of a cover c² held in position by bolts and nuts c³.
Passing through apertures provided for that purpose in the cover 62 of the cell
or pot bare arranged a number of feed tubes d of iron or other suitable material,
and the upper ends of which are formed with funnel shaped mouths through
which the battery is fed with fuel, as hereinafter described.
Or, the feed tubes & might be otherwise arranged but so as to communicate with
the lower part of the cell or pot b, as will be readily understood
Within the cell or trough bis placed a suitable quantity of lead 64 which is main-
tained in a molten condition by means of a gas or other fire arranged within the
furnace a beneath the cell or trough b, and within the porous pot c is placed a
suitable quantity of a special compound which is also maintained in a fused
condition by the gas or other fire in the furnace a.

page_text: This compound consists of the following ingredients combined in or in about
the proportions stated, namely:-
In preparing this compound, the chromium tri-oxide and caustic soda, or caustic
potash are first fused and well mixed together, then the bi-chromate of potash is
added while the other ingredients are in a fused state, the whole being thoroughly
stirred during the mixing operation.
The carbonaceous fuel, which may consist of granulated or broken coal, coke,
charcoal, wood carbonaceous gas, carbonaceous liquid or other suitable carbonaceous
material or materials, is from time to time forced through the feed tubes d by
means of plungers, pumps or other suitable means and is thus fed into the molten
lead surrounding the porous pot c.
The fused exciting compound gives up its oxygen through the porous pot c to
the molten lead within the cell or pot & which molten lead in turn gives it up
to the carbonaceous material with which it combines, reducing the same to ash
which may be removed from time to time, and generating electricity whilst the
oxygen escapes in the form of carbonic acid by a pipe 65 carried by the cover 6°
of the pot b, which conveys it to any desired destination.
In order to replace the oxygen taken from the exciting compound of the
porous pot e air or other oxidising agent is forced into the same at the lower part
of the porous pot e through a pipe e at its lower end terminating in a perforated
bulb or rose or the like e¹ and this pipe passes through a central aperture provided
in the cover
from which it is insulated by means of suitable insulating material e*
and at its upper end the pipe e is by a branch e2 connected with a supply of air
or other oxidising agent.
By these means, so long as the battery is fed with fuel through the pipes d, that
is to say, with the carbonaceous material, and with an efficient supply of air or
other oxidising agent through the pipe e a constant current of electricity will be
maintained at the expense of such carbonaceous fuel.
The poles or terminals of the battery may be arranged in any suitable position,
for example, when the cell or pot b is formed of iron, a lug or projection 6** upon
the cell or pot b may constitute one of the poles or terminals, whilst a binding
post e** at the upper part of the pipe e supplying air to the porous pot c may
constitute the other pole or terminal, or the poles or terminals may be arranged in
any other convenient way, as will be readily understood.
By the means hereinbefore described, a powerful primary battery is obtained,
the cost of which is merely nominal, practically the only waste that takes place
being the consumption of carbonaceous material and oxygen, the cost of which is
insignificant.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. In an electric battery, in which a porous pot containing an electrolyte is
suspended within a cell containing another electrolyte and heated by a suitable
furnace one of such electrolytes being fed with carbonaceous matter and the other
with oxygen, a compound consisting of bi-chromate of potash, chromium tri-oxide
and caustic soda, or its equivalent caustic alkali, caustic potash, in suitable
proportions for the oxygen fed electrolyte, substantially as herein described.
2. In an electric battery, the combination of a cell or trough, a quantity of lead
within the cell or trough, fed with carbonaceous material, a porous pot suspended

page_text: within the cell or trough and containing a compound consisting of bi-chromate of
potash, chromium tri-oxide and caustic soda, or its equivalent caustic alkali;
caustic potash, in suitable proportions, fed with an oxidising agent, and a gas or
other fire beneath the cell or trough, substantially as herein shown and described
and for the purpose stated.
