COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 11th April 1872, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE; of the British and Foreign Patent Offices, 18;
Rue de la Chaussée d'Antin, Paris, France, and 6, Piccadilly, in the
County of Middlesex, Patent Agent, send greeting.

page_text: WHEREAS I am in possession of an Invention for "IMPROVED MODE
AND MEANS FOR OBTAINING IMITATION PAINTINGS OF TAPESTRY,” communicated
to me by Edouard Charton, a person resident at Blois, France,
Gentleman, and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for the
same, and made solemn Declaration that it is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do
hereby declare that the following Complete Specification, under my
hand and seal, fully describes and ascertains the nature of the said
Invention, and the manner in which the same is to be performed, 1
that is to say:-
.
The Invention communicated to me relates to means and process
by which paintings are obtained, which imitate and can be taken for
the paintings well-known as tapestry of the Gobelin's or of Beauvais.
It consists in using conjointly with mineral or vegetable colours woven 1
jute, alone or mixed with flax, hemp, and cotton, or one of these plants.
By the process herein described, by which the said mineral or vegetable
colours are prepared, the said colours constitute pigments by means
of which the tissue composed with the said plants are penetrated more
readily with the said colours and are rendered indestructible. These 2
plants are preferably used when woven in the same manner as the
stuffs known as reps, and thereby their surfaces being ribbed have the
appearance when painted of tapestry, which the said Invention relates
to imitate.
The mineral colours are previously mixed with sulphuric acid, nitric 2
acid, acetic acid, in equal proportions. These colours are well ground
and triturated, and in order to make use of them they are afterwards
mixed and liquefied with alcohol and ammonia, in the proportion of
about three ounces and a half of colouring matter to about a quart
of alcohol, and about seven ounces of ammonia. When thus prepared, 3
the said colours can be applied with the brush on the surfaces of the
woven plants above indicated in the same manner as the ordinary
¨ colours are applied by the artists painters on to cloth.
In certain cases the ordinary colours can be used ground and
triturated as the mineral colours alone, or mixed with alcohol, or mixed 3
with the colouring reactifs herein stated.
The weaving worked with golden thread like the ancient tapestry can

page_text: be imitated by applying leaves of gold on to the said tissue and by
using a pigment of melted copal, gum, and wax previously applied on to
the said tissue.
Having thus described the nature of the said Invention, and the
5 manner of carrying the same into effect, I would have it understood
that I do not confine myself to the precise details above enumerated,
as these may obviously be modified without departing from the principle
of the Invention, but what I claim is,―
1stly. The combination of woven jute alone, or mixed with flax,
hemp, and cotton, with mineral colours mixed with sulphuric acid,
nitric acid, and acetic acid, to obtain paintings imitating tapestry, in the
manner substantially as described.
2ndly. The combination of woven jute alone, or mixed with flax,
hemp and cotton, or one of these plants, with ordinary colours, alone
5 or mixed with sulphuric acid, nitric acid, and acetic acid, to obtain
paintings imitating tapestry, in the manner substantially as described.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereto set my hand and seal, this First day of March, in the year
of our Lord One thousand eight hundred and seventy-two.
