page_text: LETTERS PATENT to Francois Burot, Merchant, of Rue Neuve des
Mathurins, 57, in the City of Paris, representing the firm of Burot, fils,
ainé & Co., Rue Neuve des Mathurins, No. 57, in the City of Paris,
(France,) for the Invention of "A NEW PROCESS FOR GILDING AND PLATING
OVER SILK. COTTON. WOOL, AND ALL OTHER TEXTILES AND FIBROUS MATTERS."
Sealed the 8th January 1858, and dated the 11th July 1857.
PROVISIONAL SPECIFICATION left by the said Francois Burot at the
Office of the Commissioners of Patents, with his Petition, on the 11th
July 1857.
I, FRANCOIS BUROT, Merchant, of Rue Neuve des Mathurins, 57, in the City
of Paris, representing the firm of Burot, fils, ainé & Co., Rue Neuve des
Mathurins, No. 57, in the City of Paris (France), do hereby declare the
nature of tho said Invention for "A NEW PROCESS FOR GILDING AND PLATING
OVER SILK, COTTON, WOOL, AND ALL OTHER TEXTILES AND FIBROUS MATTERS," to be.
as follows:-
The manufacturing of stuff's worked or figured with gold or silver has
hitherto been performed by means of draw wires, having the twofold incon-
venience of rendering the stuffs rigid and heavy, and of being employed only as
weft.
My Invention consists in employing processes of gilding and plating silk
and other textile threads which may be used not only as weft, but also as
chain or warp, and I am thus enabled to produce many novel and economical,
effects in weaving.

page_text: One process consists in arranging the silk or other threads in a tight
position, and then 1 immerse them in a solution of azotate of silver, into which
is added ammoniac until the solution becomes perfectly fluid. After one or two
hours' immersion the thread is to be dried, and submitted to a current of pure
hydrogen gas; the threads are then in a metallic state and will conduct a
current of electricity; they are then to be gilded by the methods usually
employed in gilding metals.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Francois Burot in the Great Seal Patent Office on the
8th January 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANCOIS
BUROT, Merchant, of Ruc Neuve des Mathurins, 57, in the City of Paris,
representing the firm of Burot, fils, ainé & Co., Rue Neuve des Mathurins,
No. 57, in the City of Paris (France), send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of July, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Francois Burot, Her special licence that I, the said Francois Burot,
my executors, administrators, and assigns, or such others as I, the said Francois
Burot, 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 NEW PROCESS FOR
GILDING AND PLATING OVER SILK, COTTON, WOOL, AND ALL OTHER TEXTILES AND
FIBOUS MATTERS," upon the condition (amongst others) that I, the said
Francois Burot, my executors or administrators, by an instrument 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 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 Francois Burot, 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
statement (that is to say) :-

page_text: The manufacturing of stuff's worked or figured with gold or silver has
hitherto been performed by means of draw wires, having the twofold incon-
venience of rendering the stuff's rigid and heavy, and of being employed only as
weft.
My Invention consists in employing processes of gilding and plating silk
and other textile threads, which may be used not only as weft, but also as
chain or warp, and I am thus enabled to produce many novel and economical
effects in weaving.
One process consists in arranging the silk or other threads in a tight
position, and then I immerse them in a solution of azotate of silver, into which
is added ammoniac until the solution becomes perfectly fluid. After one or
two hours' immersion the thread is to be dried and submitted to a current of
pure hydrogen gas; the threads are then in a metallic state, and will conduct
a current of electricity; they are then to be gilded by the methods usually
employed in gilding metals.
Having thus fully described the nature and particulars of my said Invention
or discovery, and the manner of carrying the same into practical effect, I
desire it to be distinctly understood that I do not confine myself to the precise
details herein described, as such may be varied without departing from the
essentials of my Invention or discovery; but I claim, and which to the best
of my knowledge and belief is new within the Realm, the process of gilding
and plating over silk, cotton, wool, and all other textile and fibrous substances,
as herein described.
In witness whereof, I, the said Francois Burot, have hereunto set my
hand and seal, this Fifth day of January, in the year of our Lord
One thousand eight hundred and fifty-eight.
Signed, sealed, and delivered by the within-
named Francois Burot, in the presence
of the sworn Interpreter undersigned,
POLD COURROUVE, witness,
