Year: 1852

page_text: LETTERS PATENT to Julien Boilesve, of 4, North Teraace,
Brompton, in the County of Middlesex, Engineer, for the Inven-
tion of "AN IMPROVED MODE OF PRESERVING VEGETABLE SUBSTANCES
AND ANIMAL COATINGS."-A communication.
Sealed the 16th April 1853, and dated the 22nd October 1852.
PROVISIONAL SPECIFICATION left by the said Julien Boilesve
at the Office of the Commissioners of Patents, with his Petition,
on the 22nd October 1852.
I, JULIEN BOILESVE, of 4, North, Terrace, Brompton, Engineer, do
hereby declare the nature of the said Invention for "AN IMPROVED
MODE OF PRESERVING VEGETABLE SUBSTANCES AND ANIMAL COATINGS," to be
as follows:-
The Invention consists in the mode of applying chlorine gas for
the preservation of vegetable substances and animal coatings.
The chlorine gas is made to expand under a bell or chamber, or an
nir-tight cloth covering over the substances to be treated; the action of
the chlorine destroys the cause of injury in an expeditious manner
without attacking the parts in a sanitary condition.

in pursuance of the conditions of the Letters Patent
filed by the said Julien Boilesve in the Great Seal Patent Office
on the 22nd April 1853.
TO ALL то WHOM THESE PRESENTS SHALL COME, I,
JULIEN BOILESVE, of 4, North Terrace, Brompton, in the County of
Middlesex, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of October, in the
year of our Lord One thousand eight hundred and fifty-two in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Julien Boilesve, Her special licence that
I, the said Julien Boilesve, my executors, administrators, and assigns,
or such others as I, the said Julien Boilesve, my executors, adminis-
trators, 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 "AN IMPLOVED
MODE OF PRESERVING VEGETABLE SUBSTANCES AND ANIMAL COATINGE," upon
the condition (amongst others) that I, the said Julien Boilesve, 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 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 I, the said Julien Boilesve, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement thereof (that is to say):
The Invention consists in the employment of chlorine or any other
sulphurous gas expanding under a bell, a box, or an air-tight cloth, or
any similar apparatus, for the preservation of grain, vegetable sub-

page_text: stances, animal coatings, and for stopping the decomposition of those
already effected, and rendering them fit for their former use, and
for destroying all the insects by which they may be attacked and
deteriorated.
The chlorine may be introduced and directed by means of a tube
into any suitable apparatus perfectly, air-tight, and containing the
substances on which I wish to operate.
These substances are so arranged that the gas can penetrate into all
their parts. In the apparatus I superpose, one upon the other, a con-
venient number of sieves in such a manner that the edge of one sieve
shall rest upon the edge of another, and a vacant and convenient space
be left for the circulation of the gas. I also make use of a cylinder
provided with a sufficient number of holes, which is also placed in an
air-tight envelope or chamber. The cylinder, being put slowly in
motion by any convenient means, will allow the grain, while traversing
the interior of the cylinder from one end to the other, to receive the
effect of the chlorine, which will escape by the lower part of the
apparatus.
And having now described the nature of the Invention, and in what
manner the same is to be performed, I wish it to be understood that I
do not confine myself to the precise details herein-before described,
provided the general features of the Invention be preserved; but what
I claim as new, and intended to be protected by the herein-before in
part recited Letters Patent, is-
.
Firstly, the employment of chlorine or other sulphurous gas for the
preservation of all kinds of vegetable substances, animal coatings, and
also for the destruction of insects, as herein-before described.
Secondly, the direct application of chlorine or other sulphurous gas
in an air-tight vessel or chamber, as herein-before described.
In witness whereof, I, the said Julien Boilesve, have hereto
set my hand and seal, this Eighteenth day of April, in the
year of our Lord One thousand eight hundred and fifty-three.
