I, JOHN LASKEY DOBELL, of No. 46, Connaught Road, Harlesden, in the County of
Middlesex, Electrical Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to that class of electric batteries in which the dissolving or
positive electrode is composed of carbon or carbonaceous material, and the negative
element of iron or other suitable metal or material, and in which a suitable exciting
fluid, such, for example, as a nitrate of a suitable metal maintained in the necessary
fluid state by the aid of heat.
In carrying the invention into effect, the battery is composed of a cell of iron or
other suitable material adapted to constitute the negative electrode or element or
the cell might be formed of other suitable material, and the negative electrode
or element might be introduced therein in another form.
Within this cell is placed a porous pot in such manner that a space is left all
around the same between it and the walls of the cell, and within the porous pot is
suspended a plate or other form of carbon or carbonaceous material, and which
constitutes the positive electrode the several parts being properly insulated where
necessary.
Within the cell and around the porous pot is placed a suitable electrolyte which
may, for example, consist of a fused nitrate of a suitable metal, or any other suitable
material, and this electrolyte is kept in a fluid condition by the aid of heat and the
efficiency thereof is maintained by the introduction thereinto of a continuous supply
of oxygen.
Within the porous pot and immediately around the carbonaceous or positive elec-
trode is placed a quantity of pure lead which is maintained in a fused or melted
state by the heat of the said outer electrolyte.
The oxygen supplied to the said outer electrolyte is drawn or passes therefrom
through the porous pot to the molten lead and thence to the carbonaceous or positive
electrode with which it enters into combination forming therewith carbonic acid gas
which escapes at a suitable opening at the top of the porous cell.
Dated this 7th day of November 1896.

I, JOHN LASKEY DOBELL, of No. 46, Connaught Road, Harlesden, in the County of
Middlesex, Electrical Engineer, 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, reference being had to the
accompanying drawing, and to the letters and figures marked thereon, that is to
say:-
My said invention relates to that class of electric batteries in which the dissolving
or positive electrode is composed of carbon or carbonaceous material and the
negative element of iron or other suitable metal or material, and in which an
exciting fluid, consisting of a nitrate of a suitable inetal is employed; and maintained
in the necessary fluid state by the aid of heat.
In the accompanying drawing, which represents a vertical section of a battery
embodying the present improvements, a represents a casing or heating chamber
which at its upper part is formed with flanges a', and within this casing or heating
chamber is suspended a cell b of iron or other suitable material adapted to constitute
the negative electrode or element and provided with a flange 61 which takes a
bearing upon the flange at of the heating chamber, a suitable ring of insulating
material being interposed between these parts or the cell b might be formed of
other suitable material and the negative electrode or element might be introduced
therein in another form such for example as that of plates or otherwise.
The cell b is closed, except as hereinafter stated, by means of a cover 62 which is
secured in place by means of bolts a fixed with the flange a¹ and nuts a', the
bolts a being insulated by means of sleeves f¹ of insulating material.
Within the cell 6 is placed a pořóus pot c in such manner that a space is left all
round the same between it and the walls of the cell b and within the porous pot c is
suspended from its cover c¹ a plate d or it might be any other form of carbon or
carbonaceous material, which constitutes the positive electrode and this cover ci is
fixed in position by means of bolts 63 fixed with the cover 62 and fly nuts 64
screwing thereon, the several parts being properly insulated where necessary by
means of insulating material f.
The negative and positive elements 6 and d are provided with terminals b* d* to
which are coupled the usual conductors and the covers of the cells b and c are
furnished with pipes b c for thé éscape of the gases evolved during the operation
of the battery and which would generally be collected and condensed.
Within the cell b and around the porous pot é is placed a suitable electrolyte b**
which consists of a fused nitrate of a suitable metal, such, for example as potassium
or sodium, either separately or combined, and this electrolyte is kept in a fused
condition by the aid of heat which may conveniently be generated in a furnace a
of the chamber a which is provided with the usual door a.
If desired, suitable quantities of barium, calcium, strontium, lead or the like may
be combined with the nitrate or nitrates constituting the electrolyte.
The efficiency of the electrolyte b** is maintained by the introduction thereinto of
a continuous supply of oxygen or suitable oxidising agent through the pipe e and
rose e and which may be in the form of ordinary atmospheric air, nitric acid vapour
or otherwise and the oxygen is forced into the electrolyte under pressure by any
suitable means.
Within the porous pot c and immediately around the carbonaceous or positive
electrode d is placed a quantity of pure lead c which is maintained in a fused or
melted state by the heat of the outer electrolyte b**.
The oxygen supplied to the outer electrolyte b** is drawn or passes therefrom

page_text: through the porous pot c to the molten lead c* and thence to the carbonaceous or
positive electrode d with which it enters into combination, forming therewith
carbonic acid gas, which escapes at the opening c² at the top of the porous cell c.
Having now particularly described and, ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that
what I claim is :-
An electric battery, comprising a cell, a porous pot suspended within the cell, a
quantity of nitrate of a suitable metal within the cell, a quantity of pure lead within
the porous pot, a negative electrode within or acting upon the nitrate, a positive
electrode immersed in the lead, a furnace for keeping the nitrate and lead in a
molten state, and a jet of air or other oxidising agent continuously injected into the
fused nitrate, substantially as herein shown and described and for the purpose
stated.
