Year: 1872

page_text: LETTERS PATENT to Henri Adrien Bonneville, of the British and
Foreign Patent Offices, 18, Rue de la Chaussee d'Antin, Paris, France,
and 6, 'Piccadilly, in the County of Middlesex, Patent Agent, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF IMITATIONS OF
TAPESTRY."-A communication from Edouard Charton, residing at
Paris, Ruc d'Antin, 15, Printer.
Sealed the 3rd January 1873, and dated the 16th July 1872.
PROVISIONAL SPECIFICATION left by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition,
on the 16th July 1872:
I, HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent
Offices, 18, Rue de la Chaussee d'Antin, Paris, France, and 6, Piccadilly,
in the County of Middlesex, Patent Agent, do hereby declare the nature
of the Invention for "IMPROVEMENTS IN THE MANUFACTURE OF IMITATIONS
OF TAPESTRY,” communicated to me by Edouard Charton, a person
resident at Paris, Rue d'Antin, 15, Printer, to be as follows:-
⚫ The Invention communicated to me relates, to improvements in the
production of imitations of the celebrated tapestry of the Gobelins and

page_text: Beauvais manufactures, and consists in the application of colours by
means of brushes to the surface of a tissue specially prepared for the
purpose.
The most important part of the Invention is the mode of manu-
facturing the tissue to which the colours are applied. For this purpose
the weft threads are each formed of from four or six threads of suitable
size, while the warp is composed of single threads of the same size,
thus producing a ribbed surface in strong relief, which when coloured
closely resembles the tone and general appearance of, the tapestry of
which the imitation forms the object of this Invention. The warp is
composed of linen thread or hemp, and jute is exclusively used for the
weft of the tissue.
SPECIFICATION in pursuance of the "conditions of the Letters Patent,
filed by the said Henri Adrien Bonneville in the Great Seal Patent
Office on the 7th January 1873.
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.
WHEREAS Her most. Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of July, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give·|
and grant unto me, the said Henri Adrien Bonneville, Her special
licence that I, the said Henri Adrien Bonneville, my executors, adminis-
trators, and assigns, or such others as I, the said Henri Adrien Bonneville,
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 "IMPROVEMENTS
IN THE MANUFACTURE OF IMITATIONS OF TAPESTRY," communicated to me by
Edouard Charton, a person resident at Paris, Rue d'Antin, 15, Printer,
upon the condition (amongst others) that I, the said Henri Adrien
Bonneville, my executors or administrators, by an instrument in writing
.

page_text: under my, or their, or one of their hands and scals, 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 Henri Adrien Bonneville, 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:-
The Invention communicated to me relates to improvements in the
production of imitations of the celebrated tapestry of the Gobelins and
Beauvais manufactures, and consists in the application of colours by
means of brushes to the surface of a tissue specially prepared for the
purpose.
The most important part of the Invention is the mode of manu-
facturing the tissue to which the colours are applied. For this purpose
the weft threads are each formed of from four to six threads of suitable
size, while the warp is composed of single threads of the same size,
thus producing a ribbed surface in strong relief, which when coloured
closely resembles the tone and general appearance of the tapestry of
which the imitation forms the object of this Invention. The warp is
composed of linen thread or hemp, and jute or other suitable material
is used for the weft of the tissue..
Having thus briefly described the nature of the said Invention, I will
proceed to explain in what manner the same may be carried into effect,
that is to say:—
For the manufacture of the tissue employed in the improved imitation
of tapestry herein referred to it is proposed to employ looms of ordinary
construction, but in order to obtain surfaces of sufficient development to
imitate without joining or seam the largest designs, it is necessary to
make the said looms of such a size (hitherto unknown) as will suffice to
produce tissues of eight metres wide and an indefinite length, and I
therefore claim the use of said looms whenever they exceed four metres
in width, constituting an application of known means to the production
of a result or an article of industry and commerce completely new.
In the decoration of the surface formed by the tissue mineral or
argilaccous colours are used alone or combined in suitable proportions.

page_text: They are carefully ground and mixed with about equal quantities of
sulfuric, nitric, and acetic acids and diluted with spirits when required
for use.
The above described process of manufacture is completely novel and
permits the production of an article of commerce hitherto unknown, in 5
other words the successful imitation by the application of colours
applied to a suitably prepared surface of the designs hitherto obtained"
at great expense by weaving together threads of different colours.
Having thus described the nature of the said Invention, and the
manner. of carrying it into effect, I claim and desire to secure by the 1
said Royal Letters Patent,―
1stly. The imitation of Gobelins and Beauvais tapestry by the
application of colours to tissue having ribbed surfaces.
2dly. The special process of manufacturing the said tissue with warp
threads of flax or hemp and weft threads of jute or other suitable 1
material, the latter being much thicker in order to produce a ribbed
surface.
3dly. The use of looms of ordinary construction for the above object
whenever they shall exceed four metres in width.
4thly. The combination of argilaceous or mineral colours alone or 2
mixed together and diluted with spirits for colouring the surfaces of the
said tissues, as above described.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereunto set my hand and seal, this Fourth day of January, in
the year of our Lord One thousand eight hundred and seventy- 2
three.
H. BONNEVILLE.
