page_text: LETTERS PATENT to Gustave Paul de L'Huynes, of 21, Frith
Street, Soho Square, Medical Doctor, for the Invention of
"CERTAIN IMPROVEMENTS IN MEDICAL PORTATIVE ELECTRO-GALVANIC
APPARATUS."
Sealed the 28th June 1853, and dated the 5th January 1858.
PROVISIONAL SPECIFICATION left by the said Gustave Paul de
L'Huynes at the Office of the Commissioners of Patents, with
his Petition, on the 5th January 1853.
I, GUSTAVE PAUL DE L'HUYNES, of 21, Frith Street, Soho Square,
Medical Doctor, do hereby declare the nature of the Invention for
"CERTAIN IMPROVEMENTS IN MEDICAL PORTATIVE ELECTRO-GALVANIC
APPARATUS" to be as follows:-
The Invention consists in forming with a plate of red copper, or of
any other negative metal, (isolated from a plate of zinc, but in communi-
cation with it by means of a piece of cloth saturated with the electro-
motive water,) an electro-galvanic battery, and in uniting this battery
to another of the same kind by putting in communication the copper

page_text: (or any other negative metal) pole of an element with the zine pole of
another element, and so on for increasing the number of batteries.
The strength of the apparatus is doubled by setting a copper or any
other negative metal plate between two zinc plates, taking care, for the
developing of the electro-galvanic current, that the negative metal plate
should not have any direct contact with the zinc plates, and to have
these last plates united together.
The electro-galvanic bath is composed of a solution of chloride of
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Gustave Paul de L'Huynes in the Great Seal
Patent Office, on the 5th July 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
GUSTAVE PAUL DE L'HUYNES, of 21, Frith Street, Soho Square, Medical
Doctor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of January, in the year
of our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Gustave Paul de L'Huynes, Her
special licence that I, the said Gustave Paul de L'Huynes; ny
executors, administrators, and assigns, or such others as I, the said
Gustave Paul de L'Huynes, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, my Invention for "CERTAIN IMPROVEMENTS IN MEDICAL POR-
TATIVE ELECTRO-GALVANIC APPARATUS," upon the condition (amongst
others) that I, the said Gustave Paul de L'Huynes, by an instrument
in writing under my hand and seal, should particularly describe and
ascertain the nature of the said Invention, and in what manner the

page_text: same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that J, the said Gustave Paul de L'Huynes, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statenient thereof, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked
thereon, that is to say:
My improvements consist in forming with a plate of red copper, or
of any other negative metal, (isolated from a plate of zinc, but in com-
munication with it by means of a piece of cloth saturated with the
electro-motive water,) an electro-galvanic battery, and in uniting this
battery to another of the same kind by putting in communication the
copper (or any other negative metal) pole of any element with the zinc
pole of another clement, and so on for increasing the number of batteries.
The strength of the apparatus is doubled by setting a copper or any
other negative metal plate between two zinc plates, taking care, for the
developing of the electro-galvanic current, that the negative metal
plate should not have any direct contact with the zinc plates, and to
have these last plates united together.
The electro-galvanic bath is composed of a solution of chloride of
sodium, hydrochlorate of ammonia, and sulphate of copper.

page_text: saturation of the pieces of cloth when the apparatus is immersed in the
electro-motive water; these holes, which are represented as round in
the Drawing, can have any other suitable shape.
Figure II, represents a front view of the apparatus set with two
elements. A, A, are the two elements, each of which is composed of two
zinc plates, with a copper plate in the centre; these three plates are
separated at their extremities by small wooden cross pieces, by means of
which each plate is isolated from the other, and the small pieces of cloth
or flannel saturated with the electro-galvanic motive water are introduced,
and serve for the development of the electro-galvanic fluid. B, B, B, B, in
the same Figure is the brass holder uniting together the two zinc plates.
C, C, are pieces of copper or any other metal conductors of the electro-
galvanic fluid. D, D, D, D, are the extremities of the copper plates
placed between the zinc plates, and which are prepared so as to receive
a ring. E, E, E, E, represent the extremities of one of the zinc plates
of each element A, A; they have a form similar to the extremities of
the copper plates D, D, in order also to receive a ring, as the two zinc
plates are jointed by the holders B, B; these extremities, E, E, give to
the electric current the power emanating from the two zinc plates.
F, F, are apertures similar to these herein-before described in Figure 1,
and represented by G, G. G, G, upper wire conductors, covered with
silk, and having a helical form to enable them to be elongated at will.
H, H, small brass plates which fasten the apparatus by means of the
springs I, I, on the part which is to receive the electro-galvanic
current. K, K, are the rings serving to unite between them the
elements composing the apparatus according to the principle of my
Invention, namely, that a zinc pole, that is to say, a positive pole, is to
be united to a copper or any other negative pole, and so on, if it is
desirable to compose the apparatus of more than two elements.

Figure III, represents a front view of an electro-galvanic truss; in
this Figure A, is the electro-galvanic clement fixed above the spring of
the truss; this apparatus, which must be composed of eight or nine
elements, more or less, is similar to the one herein-before described,
with, however, the following modifications: B, B, small plates, similar to

page_text: the small brass plates H, H, of Figure 2, and which are inserted into
the pressure cushions of the truss; C, C, pressure cushions; D, spring
of the truss; E, part of the ligament of the truss passing under the
tie; F, F, conductor threads communicating with the electro-galvanic
apparatus A; one of these threads is in communication with the zinc
pole, and the. other with the other negative metal pole.
Figure IV, represents a front view of an apparatus composed of six
electro-galvanic elements. In this Figure A, A, A, are the zinc plates,
B, B, B, the plates of copper, or any other negative metal; C, C, are
sinall metallic pieces serving to hold the string by which the apparatus
is fastened. 'D, D, D, D, are the rings serving as conductors from the
plates of zinc to a plate of copper. E, E, are the small metallic plates
for fastening the apparatus on the intended parts. F, F, are the spirál
wire conductors covered with silk. G, G, silk strings' serving to tie
together the several elements, and to maintain near one another the
plates of the said clements. H, HI, strings serving to fasten the
apparatus. I, string serving to fasten the small metallic plates (E, E,)
to their proper places.
The above-described apparatus is provided with only two plates for
each element, and between each of them a piece of cloth or flannel
saturated with the electro-motive water for developing the electro-
galvanic fluid is placed.
In the element represented by Figure V, the copper plate is cut, as
shewn in Figure 7, at B, which is filled up by a small wooden or
leather piece in such a manner that small rivettings being prepared in
C, C, C, C, the three plates are held united, and the two zinc plates
communicate by means of the four brass wires rivetted at C, C, C, C,
without being in contact or communicating with the negative copper or
metallic plate, because the said plate is cut as shewn in B, Figure VII,
so that the brass wires pass through the wooden or leather piece.
In Figure. VI, A, represents a tube, B, the electro-galvanic spiral
conductor wire covered with silk. That apparatus replaces one of the
small plates H, of Figure 2, when the electro-galvanic current is to be
established into the rectum.

page_text: In Figure VIII, A, is a probe, B, is the electro-galvanic spiral con-
ductor wire covered with silk. This apparatus replaces one of the
small plates H, of Figure 2, when the current is to reach the bladder.
The apparatus constructed in conformity with the Invention takes
several denominations, according to the different parts of the human
body it may be applied to; thus, if placed round the body it is a belt;
if round the arm a bracelet, &c. &c.
•
The principle on which the Invention is founded consists in a red
copper or other metal plate being isolated from a zinc plate by means of
a piece of cloth or flannel saturated with electro-motive water, forming
an electro-galvanic battery; each of these electro-galvanic batteries is
united to another by putting in communication the copper pole of one
The same
clement with the zinc pole of another element, and so on.
apparatus acquires a double power by placing a copper plate between two
zinc plates; taking care, however, for the development of the galvanic
current, that the copper plate should not be in direct contact with the
zinc plate, and these last be united together. When the apparatus is to
be put in operation it is immersed into the electro-motive water, com-
posed of a solution of chlorine of sodium, of hydrochlorate of ammonia,
or of sulphate of copper, or of any other acidulated solution.
The external parts of the plates are varnished, oxidizing when they
are immersed into the electro-galvanic bath.
The wire conductors are galvanized with gold to prevent them
oxidizing. It will be easily understood that the elements composing
the apparatus can have any convenient forms, either square, oval, or
even round, the effect of the Invention being always the same.
And having now described my Invention, and the best manner in
which the sanuc is to be performed, I wish it to be understood, as stated
before, that I do not confine myself to the precise details of construction
of the several parts or organs herein-before described; but what I claim
as new, and as the Invention intended to be protected by the said in
part recited Letters Patent, is,-
The construction of a portative medical galvanic apparatus by com-
bining relatively one with the other a negative with a positive metal, as

page_text: herein-before described, reference being had to all the Figures of the
Drawing.
In witness whereof, I, the said Gustave Paul de L'Huynes, have
hereunto set my hand and seal, this Fourth day of July, in the
year of our Lord One thousand eight hundred and fifty-three.
