Complete Specification Left, 2nd Feb., 1892-Accepted, 5th Mar., 1892
PROVISIONAL SPECIFICATION.
Improvements in Galvanic Batteries.
I, REGINALD HADDAN of the firm of Herbert & Co. Patent Agents of
18 Buckingham Street Strand W.C. in the County of London, Civil Engineer, do
hereby declare the nature of this invention a communication to me from abroad
by Isidoro Cabanyes of Boulevard Henri IV. Paris in the Republic of France
Manufacturer to be as follows:-
:-
The improved galvanic battery or cell is constructed as follows: the outer case or
cell is preferably composed of two cases of wood, one within the other a slight space
being left between the two which is filled with melted paraffin, the wood being also
coated with paraffin. The carbon electrode is composed of a number of prismatic
carbon rods grouped together in a cylindrical or prismatic figure, their upper ends
being connected by and fixed to a copper connecting ring. A suitable number pre-
ferably four of these groups are connected together to form one electrode. The zinc
rods are separately connected by suitable clips to cross rods preferably also of zinc
supported upon a frame of wood so that any zinc rod may be at any time removed
and replaced without interrupting the working of the battery, or all the rods may
be drawn up out of the solution in the known manner when the battery is not in
use. The zine rods dip into porous jars placed within each group of carbons
respectively.
The solution for the carbons in the outer case or jar consists of a mixture
of equal parts of nitric acid and hydrochloric acid mixed together and to which
is added an equal quantity of water acidulated with five per cent. of sulphuric
acid.
The depolarizing solution consists of a solution of chloride of sodium.

Improvements in Galvanic Batteries.
I, REGINALD HADDAN, of the firm of Herbert & Co., Patent Agents, of
18 Buckingham Street, Strand, W.C., in the County of London, Civil Engineer, do
hereby declare the nature of this invention, a communication to me from abroad
by Isidoro Cabanyes, of Boulevard Henri IV., Paris, in the Republic of France,
Manufacturer, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
The improved galvanic battery or cell is constructed as follows: The outer case
or cell
preferably composed of two or more cases of wood, one within the other
a slight space being left between the two which is filled with melted paraffin, the
wood being also coated with paraffin. For large cells this outer case or vase is
made of four wooden cases one within the other, the two outer cases are about 3rds
of an inch thick the two inner are about 3rd of an inch thick. They are when put
together about th of an inch apart and these spaces are filled with paraffin melted
and poured in, each case being also preferably soaked in melted paraffin before
putting together. The carbon electrode is composed of a number of prismatic
carbon rods grouped vertically together in a cylindrical or prismatic figure,
their upper ends being connected by and fixed to a copper connecting ring. A
suitable number, preferably four, of these groups are connected together to form

page_text: one electrode. The zine rods are separately connected by suitable clips to cross
rods preferably also of zinc supported upon a frame of wood so that any zinc rod
may be at any time removed and replaced without interrupting the working of the
battery, or all the rods may be drawn up out of the solution in the known manner
when the battery is not in use. The zinc rods, of which there is one to each group
of carbons, dip into porous jars placed one within each group of carbons respectively.
The solution for the carbons in the outer case or jar consists of a mixture of
equal parts of nitric acid and hydrochloric acid to which mixture is added water
acidulated with five per cent. of sulphuric acid. The volume of water is equal to
the volume of the two acids together.
The solution in which the zinc rods dip consists of a solution of chloride of
sodium.
The annexed drawing illustrates the improved cell,
Fig. 1 being a vertical section; Fig. 5 a plan and Fig. 6 a perspective view,
partly broken away, of the cell.
Fig. 2 shows one of the porous vases.
Fig. 3 is the carbon electrode.
Fig. 4 the zinc electrode.
Fig. 7 one of the clips which secures one of the zinc bars to the cross rod which
supports it.
A is the outer vase here shown made of three thicknesses of wood a a¹³, the
two notched bars B B carry the frame C with the two zinc cross bars electrically
connected c c. Dare the zinc rods suspended by clips d from said bars c c..
E are
the carbon rods assembled as described and secured by and on the copper band F.
g and are the two connecting strips or terminals. J the porous jar.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A galvanic battery element consisting of an outer case composed of several
thicknesses of wood separated by layers of paraffin, carbon electrode formed of
carbon rods connected and arranged in several connected groups as described,
frame C with rods e e zinc rods D suspended from the rods ee and porous vases J
the whole arranged substantially as set forth.
Dated this 2nd day of February 1892.
