A PROCESS TO PREPARE AND PRESERVE PAPER AND TISSUES WITH A SOLUTION OF PERCHLORIDE
Year: 1867

page_text: LETTERS PATENT to Gustave Gabillon, of No. 7, Rue Joquelet, Paris,
in the Empire of France, Chemist, for the Invention of "A PROCESS TO
PREPARE AND PRESERVE PAPER AND TISSUES WITH A SOLUTION OF PERCHLORIDE
Sealed the 31st December 1867, and dated the 9th July 1867.
PROVISIONAL SPECIFICATION left by the said Gustave Gabillon at the
Office of the Commissioners of Patents, with his Petition, on the
9th July 1867.
1, GUSTAVE GABILLON. of No. 7, Rue Joquelet, Paris, in the Empire of
France, Chemist, do hereby declare the nature of the said Invention for "A
PROCESS TO PREPARE AND PRESERVE PAPER AND TISSUES WITH A SOLUTION OF PER-
CHLORIDE OF IRON, INTENDED FOR STOPPING THE BLEEDING OF WOUNDS," to be
as follows:
The perchloride of iron possesses hemostatic properties in a high degree,
and paper or tissue prepared with it being applied on wounds instantly stops
the bleeding.
It is indeed well known that perchloride of iron possesses the property of
stopping the effusion of blood, but the solution which was to be used directly
offered some difficulties, and could not be readily applied nor carried about.

page_text: The paper or tissue to be impregnated with a solution of perchloride of iron
undergoes a first preparation to render it supple, and to prevent the destruction
of its fibres when dry it is dipped in a saturated solution of perchloride of
iron. Now the hemostatic properties acquired would be lost after a short time
if this paper were left in the open air or folded in a cloth or in common paper,
the part of the Invention relative to the preservation of the impregnated
paper, which is yellow, consists in wrapping it in a waterproof taffeta prepared
with an addition of resinous substances, which allows the impregnated paper
to be kept for any length of time always ready for use.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Gustave Gabillon in the Great Seal Patent Office on the
8th January 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GUSTAVE
GABILLON, of Number 7. Rue Jacquelet, Paris, in the Empire of France,
Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of July, in the year of our Lord One
thousand eight hundred and sixty-seven. in the thirty-first year of Her reign,
did for Herself, Her heirs and successors, give and grant unto me, the said
Gustave Gabillon, Her special licence, that I, the said Gustave Gabillon, my
executors, administrators, and assigns, or such others as I. the said Gustave
Gabillon. 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, an Invention for "A PROCESS TO PREPARE AND
PRESERVE PAPER AND TISSUES WITH A SOLUTION OF PERCHLORIDE OF IRON, INTENDED
FOR STOPPING THE BLEEDING OF WOUNDS," upon the condition (amongst others)
that I, the said Gustave Gabillon my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention. and in
what manner the same was to be performed, and cause the same to be filed in
the Great Patent Seal Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Gustave Gabillon, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement:-
The hemostatic (or "hoemostatic ") properties of perchloride of iron are well
known, but hitherto it has been used for this purpose only in a liquid state, as
it was not thought possible to obtain or prepare this substance in a more con
venient form for ready application, and thus io introduce it into more general
use. The main cause preventing the use of perchloride of iron in combination
with another material is its destructive nature. It is by paralysing this cause
that I succeed in applying this ferruginous compound on paper and tissues of
all kinds. Accordingly I have combined a preparation to prevent the said
papers and tissues being eaten by the perchloride of iron, and consequently to
impart to them the property of receiving and keeping the said perchloride of
iron in a convenient form, which allows it to be used very easily wherever it
may be required. It is this particular fact of rendering paper and tissues
impervious to the attack of perchloride of iron by means of a protecting pre-
paration, and thereby obtaining the said perchloride in a supple and solid state
which constitutes the main basis of my Invention.
My process consists of two principal points:-Firstly, the actual pre-
paration of paper or tissues with perchloride of iron; secondly, the mode of
permanently preserving the said paper when prepared with the perchloride of
iron. The paper or tissues are at first coated with the protecting composition,
this being effected by dipping them in the following solution, namely, one
pound of benzoin resin of first quality, one pound of rock alum, and four and
gallons of water. The whole is thrown into a suitable vessel, say, an
earthen or a copper one, carefully tinned on the inner side: this vessel is
placed over the fire and heated to the boiling point: the solution must be
kept boiling during four hours, and be stirred from time to time. The
evaporated water is replaced by the same quantity of fresh water, and as soon
as the solution is cooled it is filtered off; the paper or the tissues to be pre-
pared are then dipped in the said solution, and remain dipping as long as may
be deemed necessary for their saturation, after which they are left to dry with
all requisite care. When in this state a solution of perchloride of iron in a
more or less concentrated state is applied over the prepared sheets of paper
or cloth in the simplest manner, for instance, by means either of a brush or
of a roller. The paper or tissue being thus prepared is folded up and carefully
preserved from the action of the atmosphere by wrapping it in a piece of
waterproof taffeta prepared with an addition of resinous substances, and is
thus preserved during any length of time in a perfect state and always ready
for use.

page_text: My Invention being now described, I desire to have it understood that I do
not claim the use of perchloride of iron as a hemostatic agent; but what I
claim is,-
The preparation of paper or tissue of any suitable kind with perchloride of
iron, as before described, to be used as a very convenient and efficacious
hemostatic agent.
And I claim also the means of preventing the said paper or tissue thus pre-
pared from being destroyed by the action of the air by folding and wrapping
it up in a piece of waterproofed taffeta prepared with an addition of resinous
substances, as above described..
In witness whereof, I, the said Gustave Gabillon, have hereunto sei
my hand and seal, this Fourth day of January, in the year of our
Lord One thousand eight hundred and sixty-eight.
