COMBINING GELATINE WITH CERTAIN OTHER SUBSTANCES, AND COLORING THE SAME SO AS TO PRODUCE VARIOUS OBJECTS CAPABLE OF RESISTING ATMOSPHERIC INFLUENCES
Year: 1853

page_text: LETTERS PATENT to Louis Cornides, of 4, Trafalgar Square,
Charing Cross, in the County of Middlesex, for the Invention of
"COMBINING GELATINE WITH CERTAIN OTHER SUBSTANCES, AND COLORING
THE SAME SO AS TO PRODUCE VARIOUS OBJECTS CAPABLE OF RESISTING
ATMOSPHERIC INFLUENCES."
Sealed the 26th May 1854, and dated the 26th November 1853.
PROVISIONAL SPECIFICATION left by the said Louis Cornides at
the Office of the Commissioners of Patents, with his Petition, on
the 26th November 1853.
I, LOUIS CORNIDES, of 4, Trafalgar Square, Charing Cross, in the
County of Middlesex, do hereby declare the nature of the said Inven-
tion for "COMBINING GELATINE WITH CERTAIN OTHER SUBSTANCES, AND
COLOURING THE SAME SO AS TO PRODUCE VARIOUS OBJECTS CAPABLE OF RESIST-
ING ATMOSPHERIC INFLUENCES," to be as follows:-
The gelatine is combined with collodium or any other suitable trans-
parent varnish, and is coloured in the following manner :-The gelatine

page_text: is first made into the form in which it is desired the object to be made
should be, by dipping a model of the object into the gelatine in a liquid
state, and then drying the coating which the model takes, and repeating
this process until the coating is of the requisite thickness, having regard
to the nature of the object to be made. The coating is then removed
from the model by being cut where requisite, the parts are then ce-
mented together with gelatine, in the form of the required object.
Instead of the above method, when the form admits of it, soft gelatine
is pressed by any of the methods of embossing now in use into the
requisite form, or liquid gelatine is cast in a mould by any method now
in use.
The object is then painted or coloured by any method now in
use with the following chemical colours or combinations of them pro-
duced as follows, which are peculiarly adapted for this purpose. Blue,
produced by dissolving indigo in sulphuric acid; red, by carmine,
cochineal, or any other vegetable red colour soluble in water or spirits
of hartshorn; yellow, by a solution of tamarind-wood or any other
vegetable yellow pigment, soluble in water and soda; brown red, by
pure silver dissolved in a neutral solution of nitric acid; brown, by
nut shells or other brown vegetable pigments boiled in water, and a
neutral solution of iron produced by sulphuric acid. When the paint
is dry, the object is dipped into collodium or any other transparent
liquid varnish capable of resisting atmospheric influence. In the
manufacture of sheets or plates, the plate is first made of gelatine by
any process now used för that purpose, and is then stretched in a frame
and dipped in the collodium or varnish above mentioned. In order to
print or paint on the sheet gelatine, the sheet is made or fixed on
glazed or varnished card-board, and is then printed or painted by any
of the processes in use for printing or painting on paper, but with the
colours above described and their combinations, and the plate is either
then stretched on a frame and dipped in the collodium, or varnished
as above described, or is preserved from atmospheric influence, in the
following manner-The sheet is placed between two plates of glass of
the same dimensions as the sheet, and the edges of the glass plates are
covered with gum or other air-tight cement, and a small hole being
left on two of the edges. The air remaining between the two plates

page_text: of glass is then exhausted, and at the same time by atmospheric pres-
sure liquid gelatine is forced through the other hole, so as to fill up the
vacuum by which the two plates of glass firmly adhere to the inter-
mediate sheet of gelatine.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Louis Cornides in the Great Seal Patent Office
on the 26th May 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
LOUIS CORNIDES, of 4, Trafalgar Square, Charing Cross, in the County
of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of November, in the:
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Louis Cornides, Her special
licence that I, the said Louis Cornides, my executors, administrators,
and assigns, or such others as 1, the said Louis Cornides, 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 torm
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 "COMBINING GELA-
TINE WITH CERTAIN OTHER SUBSTANCES, AND COLORING THE SAME SO AS TO
PRODUCE VARIOUS OBJECTS CAPABLE OF RESISTING ATMOSPHERIC INFLUENCES,"
upon the condition (amongst others) that I, the said Louis Cornides, 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 Louis Cornides, do hereby
declare the nature of the said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say): —
.
The mode by which my Invention is to be and may be carried into
practical effect, is as follows:-
The gelatine is combined with collodium or any other suitable trans-
parent varnish, and is colored in the following manner :-The gelatine
is first made into the form in which it is desired the object to be made
should be, by dipping a model of the object into the gelatine in a liquid
state, and then drying the coating which the model takes, and repeating
this process until the coating is of the requisite thickness, having regard
to the nature of the object to be made. The coating is then removed
from the model by being cut where requisite, the parts are then
cemented together with gelatine in the form of the required object.
Instead of the above method, when the form admits of it, soft gelatine
is pressed by any of the methods of embossing now in use into the re-
quisite form, or liquid gelatine is cast in a mould by any method now in
use. The object is then painted or colored by any method now in use,
with the following chemicals, colors, or combinations of them produced
as follows, which are peculiarly adapted for this purpose:-Blue, pro-
duced by dissolving indigo in sulphuric acid, and diluted with water;
red, by carmine, cochineal, or any other vegetable red color soluble in
water or spirits of hartshorn; yellow, by a solution of tamarind-wood or
any other vegetable yellow pigment soluble in water and soda; brown
red, by pure silver dissolved in a neutral solution of nitric acid; brown,
by nut shells or other brown vegetable pigments boiled in water, and a
neutral solution of iron produced by sulphuric acid. When the paint
is dry, the object is dipped into collodium or any other transparent
liquid varnish capable of resisting atmospheric influence. In the
manufacture of sheets or plates, the plate is first made of gelatine by
any process now used for that purpose, and is then stretched in a frame
and dipped in the collodium or varnish above mentioned. In order to
print or paint on the sheet gelatine, the sheet of gelatine is made or
fixed on glazed or varnished card-board, and is then printed or painted
by any of the processes in use for printing or painting on paper, but
with the colors above described and their combinations, and the plate

page_text: is either then stretched on a frame and dipped in the collodium or
varnish, as above described, or is preserved from atmospheric influence
in the following manner :-The sheet is placed between two plates of
glass of the same dimensions as the sheet, and a narrow margin of the
sheet of gelatine on both sides is melted with dilute nitric acid; the
three are then pressed together in a receptacle from which the air is
exhausted, by which the two plates of glass firmly adhere to the inter-
mediate sheet of gelatine.
In witness whereof, I, the said Louis Cornides, have hereunto set
my hand and seal, this Twenty-sixth day of May, in the year of
our Lord One thousand eight hundred and fifty-four.
