CERTAIN MEANS OF OBTAINING MARKS AND DESIGNS IN PAPER
Year: 1853

page_text: LETTERS PATENT to Jean Durandeau, Junior, of Paris, in the
Empire of France, and of Castle Street, Holborn (City), London,
General Manager of the firm Durandeau Junior and Chauveau,
for the Invention of "CERTAIN MEANS OF OBTAINING MARKS AND
DESIGNS IN PAPER."
Sealed the 2nd December 1853, and dated the 3rd June 1853.
PROVISIONAL SPECIFICATION left by the said Jean Durandeau
at the Office of the Commissioners of Patents, with his Petition,
on the 3rd June 1858.
I, JEAN DURANDEAU, Junior, of Paris, in the Empire of France,
and of 16, Castle Street, Holborn (City), London, General Manager
of the firm Durandeau Junior and Chauveau, do hereby declare the
nature of the said Invention for "CERTAIN MEANS OF OBTAINING MARKS
AND DESIGNS IN PAPER" to be as follows:-
This Invention consists in transferring marks in paper during the
process of satining; though these marks may be transferred on the

page_text: zinc plates or other metal plates used in satining by different means,
I particularly insist on the process consisting in engraving in hollow on
a metal or other plate, sufficiently hard, the mark or design wished
to be obtained on the paper. By making this engraved plate pass
with the satining metallic sheets, between the cylinders of a laminating
machine, the pressure forces the metallic sheet to penetrate into the
hollow of the engraving, making a relievo on this metallic sheet. It
is easy to understand that by passing one after the other all the
satining metallic sheets each will receive the same impression, and
each sheet of aper will have in its thickness exactly the same design
and at the same places. This small metallic relievo being solid, and
taken in the thickness of the satining metallic plate, will be firm and
lasting; thus the satining plates will be durable, and there will scarcely
be any increase of expense.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jean Durandeau in the Great Seal Patent Office,
on the 3rd December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JEAN DURANDEAU, Junior, of Paris, in the Empire of France, and of
Castle Street, Holborn (City), London, General Manager of the firm
Durandeau Junior and Chauveau, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of June, in the year of our
Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Jean Durandeau, Her special licence that I,
the said Jean Durandeau, my executors, administrators, and assigns,
or such others as I, the said Jean Durandeau, my executors, adminis-
trators, 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

page_text: Islands, and the Isle of Man, an Invention for "CERTAIN MEANS OF
OBTAINING MARKS AND DESIGNS IN PAPER," upon the condition (amongst
others) that I, the said Jean Durandeau, by an instrument in writing
under my hand and seal, 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 Jean Durandeau, 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):
This Invention consists in transferring marks in paper during the
process of satining; though these marks may be transferred on zinc
plates or other metal plates used in satining by different means, I par-
ticularly insist on the process consisting in engraving on a metallic
plate, sufficiently hard, the mark or design wished to be obtained on
the paper. By passing this engraved plate with the satining metallic
sheets between the cylinders of a laminating machine, the pressure
forces the metallic sheet to penetrate into the hollow of the engraving,
making a relievo on this metallic sheet. It is easy to understand that
by passing one after the other through the laminating machine all the
satining metallic sheets with the engraved sheet each will receive the
same impression, and each sheet of paper satined by means of these
plates will have in its thickness exactly the same design and at the
same places. This small metallic relievo being solid, and taken in the
thickness of the satining metallic plate, will be firm and lasting; thus
the satining plates will be durable, and there will scarcely be any
increase of expense. By this process the satining takes place according
to the ordinary method; that is to say, by passing between smoothing
cylinders packets of sheets of paper alternately with sheets of zinc
bearing the designs in relief, and after this the reliefs become impressed
in the sheets of paper.
I claim the means above described of obtaining upon paper manu-
factured mechanically and in a continuous manner marks, engravings,

page_text: and designs, similar to those obtained by the aid of water marks in
paper made by hand, these designs being obtained during the operation
of satining, as has been above described.
In witness whereof, I, the said Jean Durandeau, Jun', have
hereunto set my hand and seal, this First day of December, in
the year of our Lord One thousand eight hundred and fifty-
three.
JEAN DURANDEAU, JR. (L.S.)
