1883.
PAUL RAOUL DE FAUCHEUX D'HUMY of Carlton Mansions Clapham Road in
the County of Surrey IMPROVEMENTS IN GALVANIC BATTERIES
The invention has for its object improvements in galvanic batteries and relates
to means whereby a battery of a given size is rendered much more powerful and
effective than when constructed in the manner heretofore adopted.
For this purpose instead of forming the negative and positive elements of the
battery of plain cylinders blocks, plates or sheets of material exposing a minimum
of surface to the exciting liquids I, according to my Invention, construct such parts
in such manner as to give them a greatly increased extent of surface.
According to one arrangement I form the said elements of fluted corrugated or
perforated tubes or plates, or I form the same of a top and bottom ring or bar
connected together by rods or bars of round, angular or other suitable section or of
combinations of rods of both round and other sections and if desired twisted. If
desired the lower bar or ring may be dispensed with. Or I form such parts of
woven wire which may be either single or double, in the latter case I fill the
intervening space with metallic oxide, turnings, borings or other material which
will increase the surface of the element exposed to the exciting liquid and assist
the developement of electricity.
Or such concentric cylinders or the plates may be made of perforated material
and filled with material as above described.

page_text: Or I form the metallic cylinder or cylinders of wire coiled into a cylindrical
form and secured in such position in any convenient manner and such coiled wire
may be employed either single or double as above described.
According to my invention I also employ metallic oxides in the construction
of the negative and positive elements described which I combine or not with other
materials and form into cylinders, plates, sheets rods or other forms as may be
required and give thereto either a plain or an extended surface.
I also employ carbon or its derivatives or compounds in the construction of one
of the elements, in which case I also form the same with extended surfaces as
above described,

PAUL RAOUL DE FAUCHEUX D'HUMY of Carlton Mansions Clapham Road in
the County of Surrey "IMPROVEMENTS IN GALVANIC BATTERIES
"
The invention has for its object improvements in galvanic batteries and relates
to means whereby a battery of a given size is rendered much more powerful and
effective than when constructed in the manner heretofore adopted.
For this purpose instead of forming the negative and positive elements of the
battery of plain cylinders blocks plates or sheets of material exposing a minimum
of surface to the exciting liquids I according to my invention construct such parts
in such manner as to give them a greatly increased extent of surface.
According to one arrangement I form the said elements of fluted corrugated or
perforated tubes or plates or I form the same of a top and bottom ring or bar
connected together by rods or bars of round angular or other suitable section or of
combinations of rods of both round and other sections and if desired twisted. If
desired the lower bar or ring may be dispensed with. Or I form such parts of
woven wire which may be either single or double in the latter case I fill the
intervening space with metallic oxide, turnings borings or other material which
will increase the surface of the element exposed to the exciting liquid and assist
the development of electricity.
Or such concentric cylinders or the plates may be made of perforated material
and filled with material as above described.
Or I form the metallic cylinder or cylinders of wire coiled into a cylindrical
form and secured in such position in any convenient manner and such coiled wire
may be employed either single or double as above described.
I also employ carbon or its derivatives or compounds in the construction of one
of the elements in which case I also form the same with extended surfaces as
above described.
And in order that my said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS
In the various figures like parts are marked with similar letters of reference.
Figure 1 is a side elevation and Figure 2 is a plan representing one element of
a galvanic battery and showing one method of carrying my invention into effect.
In this case I employ a top ring a and a bottom ring a connected together by rods
or bare b of round section. I connect the top and bottom rings together by means
of nuts c screwing on to the ends of some of the rods or bars b and in order to
facilitate the cleansing of the rods or bars 6 I mount them loosely in the rings a. a'.
except those which are fixed by the nuts c by which means by introducing a
rubber between the various rods and bars b and moving said rubber to and fro
I am enabled readily to cleanse them. d is a terminal to which a conducting wire
is attached.
Instead of forming the rods or bars b of round section they may as shown at
Figures 3 and 4 be of square section or as shown at Figures 5. 6. 7 and 8 they
may be of angular section twisted or they may have the section shown at Figures 9

page_text: At Figures 11 and 12 I have shown the rods or bars b with a wire b' twisted
around them and such wire b¹ may be applied to bars or rods b of other section
and may be either twisted or not as may be required.
At Figures 13 and 14 the rods or bars are represented of cruciform section
with wires b' lodged in the angular spaces around the same and if desired the rods
or bars 6 may be of other sections having longitudinal grooves around the same in
which wires 6 are lodged.
At Figures 15 and 16 the rods or or bars 6 are represented as surrounded by a
loosely fitting perforated tube 62.
If desired the lower bar or ring a¹ may be dispensed with as shown at Figure 17
in which case the bars or rods b will all be rigidly connected to the top bar or ring a.
At Figures 18 and 19 I have represented an elevation and plan of another
method of carrying my Invention into effect. In this case I employ two perforated
cylinders b. b. connected together in any convenient manner so as to leave an
annular space between them.
Or such cylinders b³. b. may be formed of woven wire as shown in sectional
elevation at Figure 20 and in plan at Figure 21 or as shown at Figure 22 bars or
rings. a. a. may be connected together by wires or rods b and coils 66. 66, of wire
may be fixed to the interior and exterior of the ring of wires or rods b
At Figure 23 I have represented the cylinders 63. 64. formed with corrugated
surfaces and at Figure 24 they are shown with fluted surfaces.
The spaces between the cylinders 63. 64. formed in any of the methods herein-
before described may be left entirely free for the circulation of the exciting liquid
between the cylinders b³. b. or if desired such space may be filled with metallic
oxide, turnings, borings or other material which will increase the surface of the
element exposed to the exciting liquid and assist the development of electricity.
I also as heretofore employ carbon or its derivatives or compounds in the
construction of one of the elements in which case I also according to my invention
form the same with extended surfaces in similar manner to those above described.
I would here remark that the rods or bars b instead of being placed in a vertical
position may be placed in a horizontal or inclined position and that other forms
having extended surfaces may be given to the negative and positive elements of a
galvanic battery without departing from the peculiar character of my Invention.
Having thus described the nature of my said invention and the mode in which
I carry the same into effect I would have it understood that what I claim is the
improvements in galvanic batteries substantially as herein shown and described
and for the purpose stated:
In witness whereof I the said Paul Raoul de Faucheux d'Humy have hereunto
set my hand and seal this thirtieth day of July in the year of our Lord One
thousand eight hundred and eighty three.
