PROVISIONAL SPECIFICATION left by the said Constantin Descat and

with their Petition, on the 20th November 1868.
We, CONSTANTIN DESCAT and HENRY GUILLAUME, both of No. 82,
Boulevard Sébastopol, Paris, in the Empire of France, Gentlemen, do
hereby declare the nature of the said Invention of "IMPROVEMENTS IN
THE MODE OF FIXING COLOURS ON TEXTILE FABRICS COMPOSED OF WOOL AND
COTTON," to be as follows:-
This Invention consists in the employment of metallic solutions of
iron, copper, manganese, or chromium, either pure, singly, mixed together,
or in conjunction with coloring matters, for printing on textile fabrics
consisting of wool and cotton, wool and thread, goats' hair and cotton,
goats' hair and thread, alpaca and cotton, alpaca and thread, and all

page_text: other tissues composed of a mixture of textile, vegetable, and animal
matters, either by means of the cylinder printing machine or otherwise,
the process being the same as that for printing thread tissues, thread
and cotton, or cotton; the fabrics are allowed to oxydize after the
application, the oxydation being completed by subjecting them to an
alkaline or bichromate bath.
other tissues composed of a mixture of textile, vegetable, and animal
matters, either by means of the cylinder printing machine or otherwise,
the process being the same as that for printing thread tissues, thread
and cotton, or cotton; the fabrics are allowed to oxydize after the
application, the oxydation being completed by subjecting them to an
alkaline or bichromate bath.
The advantages of the application of this system to the tissues named
is that the colours or tints obtained are unchangeable either by the
action of light or washing.
SPECIFICATION in pursuance of the conditons of the Letters Patent,
filed by the said Constantin Descat and Henry Guillaume in the
Great Seal Patent Office on the 9th March 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CONSTANTIN
DESCAT and HENRY GUILLAUME, both of No. 82, Boulevard Sebastopol,
Paris, in the Empire of France, Gentlemen, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of November, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Constantin Descat, and Henry Guillaume,
our Her special licence that we, the said Constantin Descat and Henry
Guillaume, our executors, administrators, and assigns, or such others as
we, the said Constantin Descat, and Henry Guillaume; our 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 "IMPROVEMENTS IN
THE MODE OF FIXING COLORS ON TEXTILE FABRICS COMPOSED OF WOOL AND
COTTON," upon the condition (amongst others) that we, the said Con-
stantin Descat and Henry Guillaume, our executors or administrators, by
an instrument in writing under our, 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 Seal Patent Office within six

page_text: calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said Constantin Descat and Henry
Guillaume, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
This Invention consists in the employment of metallic solutions of
iron, copper, manganese, or chromium, either singly, mixed together, or
in conjunction with coloring matters, for printing on textile fabrics con-
sisting of wool and cotton, wool and thread, goats' hair and cotton,
goats' hair and thread, alpaca and cotton, alpaca and thread, and all
other tissues composed of a mixture of textile, vegetable, and animal
matters, either by means of the cylinder printing machine or otherwise,
the process being the same as that for printing thread tissues, thread
and cotton, or cotton; the fabrics are allowed to oxydize after the
application of the solutions and coloring matters, the oxydation being
completed by subjecting them to an alkaline or bichromate bath.
The advantages of the application of this system to the tissues named
is that the colors or tints obtained are unchangeable either by the
action of light or washing.
Having thus described our Invention, what we claim and desire to
secure by Letters Patent is, the application of the above-named metallic
solutions, singly, mixed together, or in conjunction with coloring matters
to the textile fabrics herein-named by the usual process of printing such
matters, oxydation being produced, as already described, by subjecting
them after the application to a bichromate or alkaline bath.
In witness whereof, we, the said Constantin Descat and Henry
Guillaume, have hereunto set our hands and seals, this Sixth day
of March, in the year of our Lord One thousand eight hundred
and sixty-nine.
