Empire of France, Printer, for the Invention of "IMPROVEMENTS IN ORNA.
Sealed 'the 24th November 1857, and dated the 6th June 1857.
PROVISIONAL SPECIFICATION left by the said Alfred Jean Vincent
Dopter at the Office of the Commissioners of Patents, with his Petition,
on the 6th June 1857.
I, ALFRED JEAN VINCENT DOPTER, of Paris, in the Empire of France;.
Printer, do hereby declare the nature of the said Invention for." IMPROVEMENTS,
IN ORNAMENTING CLOTH, WOOD, METAL, LEATHER, AND OTHER SURFACES," to be as.
follows:-
My Invention consists in printing or impressing colourings or paintings on
cloth, wood, porcelain, enamel, glass, ivory, mother-of-pearl, stones, frescos, ":
parchment, leather, metals, and paper, &c. For this purpose, firstly, I cover
the surfaces to be coloured, either by a lithographic press or by. a reversed.
tracing, with an agglutinative or adhesive coating; secondly, I sprinkle
powdered colours on these coated surfaces. These colours are deposited on
the adhesive material, either firstly (a), by. a surface or plate divided into
compartments(hollowed out therein) which compartments contain the colours,/
or, secondly (b), by perforated patterns.
Firstly (a), this plate divided into compartiments is mounted on woodjorany:
other material suitable for a body, the designofthe compartments which must

page_text: be the same as the drawing to be produced on the surface to be coloured or
printed on is produced on the plate by the aid of an impression or bya reversed
tracing. This doue the concave compartments are formed, then furnished
with the different colours which it is desired to apply on the surface. The
surface to be ornamented is applied on the hollowed surface containing the
colour and the whole is reversed. The powdered colour falls on and adheres
to the drawing formed by the adhesive coating which furnishes the coloured
impression. The work is then slightly touched up by hand. The concave
compartments are formed in the manner of wood engravings.
Secondly (b), I colour the surfaces by placing a perforated pattern over
them and by sprinkling the necessary parts of it with the desired colour or
colours. The colours pass through the perforations, and will adhere to the
adhesive coating. The colours employed are mineral, vegetable, soluble,
fusible, or of other kinds.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Jean Vincent Dopter in the Great Seal Patent
Office on the 4th December 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
JEAN VINCENT DOPTER, of Paris, in the Empire of France, Priuter, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of June, in the year of our Lord One
thousand eight hundred and fifty-seven in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Alfred Jean Vincent Dopter, Her special licence, that I, the said Alfred Jean
Vincent Dopter, my executors, administrators, and assigns, or such others as
I, the said Alfred Jean Vincent Dopter, 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 ORNAMENTING CLOTH, WOOD METAL, LEATHER, AND OTHER
SURFACES," upon the condition (amongst others) that I, the said Alfred Jean
Vincent Dopter, 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

page_text: 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 Alfred Jean Vincent Dopter 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 :-
I
My Invention consists in printing or impressing colours for painting or
ornamenting on cloth, wood, porcelain, enamel, glass, ivory, mother-of-pearl,
stones, fresco's, parchment, leather, metals, papers, &c. For this
purpose
first cover the surfaces to be coloured, either by a lithographic press or
by transferring an agglutinative or adhesive coating; secondly, I sprinkle
powdered colours on the coated surfaces. These colours are deposited on the-
adhesive material, either (1st) by a surface or plate divided into compartiments
recessed therein, which compartments contain the colours; or (2nd) by
perforated patterns, or by means of a stretched skin, cloth, or other tissue, or
by a surface of any material which I place on the colours of the several
compartments, in order to take the différent coloured powders it contains and
transfer them on the impression which is to be coloured by them. These
compartments serve for the application of all pulverized metals, for mordants
used in dyeing, for powdered colours of all kinds, such as the colours used for
stuff goods, termed vapour colours, colours of application, such as water
colours generally, colours for painting on porcelain, glass, enamel, oil colours,
crayon and aquarelle colours, &c.; lastly, for all colours that are soluble,
fusible, or friable in fatty matters.
First, the plate or surface divided into compartments, is made of wood, or
any other suitable material; the design of the compartments which must be
the same as the drawing to be produced on the surface to be coloured or
printed, is produced on the plate by impression or by a transfer. This done
the concave compartments are then formed and afterwards furnished with the
different colours which it is desired to apply on the surface to be ornamented.
The surface to be ornamented is applied on the hollowed surface containing
the colour, and the whole is reversed. When so reversed, the colour falls in
powder and adheres to the drawing formed by the adhesive coating which
thus produces the coloured impression. The work is then slightly touched up
by hand. The concave compartments are formed in the manner of wood
engraving.
Secondly, I colour the surfaces by placing a perforated pattern over them
and by sprinkling the necessary parts of it with the desired colour or colours.

page_text: The colours pass through the perforations and will adhere to the adhesive
coating. The colours employed are mineral, vegetable, soluble, fusible, or of
other kinds.
Having described the nature of my Invention, and the manner of per-
forming the same, I declare that what I claim as the Invention to be secured
by the herein-before in part recited Letters Patent is,―
First, the use of a surface or plate, having compartments or recesses
furnished with colours or metals in powder, agreeing and registering with a
printed adhesive inpression on which such colours are to be sprinkled by a
movement given to the whole of such recesses, in order to agitate and deposit
the powders on the adhesive matter of the impression.
Secondly, the use of either a stretched skin, cloth, or any other fabric, or a
surface of any material which I place on the assembled colours in the several
compartments for the purpose of transferring them to the impression which is
to be coloured by them.
Thirdly, the forming a recessed surface for the powdered colours, either in
wood, metal, skin, fabric, india-rubber, gutta percha, paste, or other material,
either by engraving, casting, wood engraving, or by soldering or glueing parts
together forming it.
And, fourthly, by layers of powdered colours placed on any material having
a plane or cylindrical surface.
In witness whereof, I, the said Alfred Jean Vincent Dopter, have
hereunto set my hand and seal, this First day of December, in the
year of our Lord One thousand eight hundred and fifty-seven.
A. J. V. DOPTER. (L.S.)
