THE PURPOSE BY MACHINERY TO POLISH WHOLY OR PARTLY LEATHER, PAPER HANGING, AND ALL OTHER FEBRIL STUFF, THAT IS TO SAY, THAT A PIECE CAN BE POLISHED IN SEVERAL PARTS LEAVING SPACES UNPOLISHED
Year: 1858

page_text: LETTERS PATENT, to Lutéreau (Adolphe André), residing at Paris, Rue
de la Goutte d'Or, 26 (Chapelle St. Denis), (Seine), in the Empire of
France, Engraver, for the Invention of "THE PURPOSE BY MACHINERY TO
POLISH WHOLY OR PARTLY LEATHER, PAPER HANGING, AND ALL OTHER
FEBRIL STUFF, THAT IS TO SAY, THAT A PIECE CAN BE POLISHED IN SEVERAL
PARTS LEAVING SPACES UNPOLISHED."
Sealed the 10th September 1858, and dated the 17th April 1858.
PROVISIONAL SPECIFICATION left by the said Lutéreau Adolphe André
at the Office of the Commissioners of Patents, with his Petition, on
the 17th April 1858.
I, LUTEREAU (ADOLPHE ANDRE) residing at Paris, Rue de la Goutte
d'Or, 26 (Chapelle St. Denis), (Seine,) in the Empire of France, Engraver, do
hereby declare the nature of the said Invention for "THE PURPOSE BY
MACHINERY TO POLISH WHOLY OR PARTLY LEATHER, PAPER HANGING, AND ALL
OTHER FEBRIL STUFF, THAT IS TO SAY, THAT A PIECE CAN BE POLISHED IN SEVERAL
PARTS LEAVING SPACES UNPOLISHED," to be as follows:-
Up to the present time materials have been often glazed, but it was found
impossible to leave spaces unglazed. By means of my Invention I can make
any reserve according to the drawings which are to be applied. For this
purpose the machine, Fig. 1, composed of two rollers, between which the
piece passes. The roller A is of hollow cast iron and heated; the roller B,
Fig. 2, is of massive cast iron with the proposed drawing in relief upon it;
on the roller A is a cog of a smaller diameter than the roller directing a
wheel placed on the roller B of a larger diameter than the above-named

page_text: roller. The roller A, directed by any transmission of power, gives the move-
ment to the roller B by means of its cog wheels. The roller A turns a great
deal quicker than the roller B, occasioning a sliding movement which is called
friction. The roller A, turning a great deal quicker than the roller B, slides on
the peice P, and by means of a certain heat and a heavy pressure gives it the
brilliancy. The hollow parts of the roller not transmitting any pressure to
the material allows it to remain in its natural state, and the parts in relief
beeing set off by the pressure gives them the glazing. The process of glazing
materials in relief is of the greatest importance on account of its cheapness
either in drawing or engraving.
It must be moreover well understood that the above process applied to the
roller as a new system of engraving remains my property, and cannot be
copied by any one even to apply it to a friction cylinder.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Adolphe André Lutéreau in the Great Seal Patent Office
on the 6th October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADOLPHE
ANDRE LUTEREAU, residing at Paris, Rue de la Goutte d'Or, 26 (Chapelle St.
Denis), (Seine), in the Empire of France, Engraver, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of April, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Adolphe André Lutéreau, Her special licence that I, the
said Adolphe André Lutéreau, my executors, administrators, and assigns, or
such others as I, the said Adolphe André Lutéreau, 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 Islands, and Isle of Man, an
Invention for "THE PURPOSE BY MACHINERY TO POLISH WHOLLY OR PARTLY
LEATHER, PAPER HANGING, AND ALL OTHER FEBRIL STUFF, THAT IS TO SAY, THAT
A PIECE CAN BE POLISHED IN SEVERAL PARTS LEAVING SPACES UNPOLISHED," upon
the condition (amongst others) that I, the said Adolphe André Lutéreau, 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

page_text: nature of the said Invention, and in what manner the same was to be per-
formed, 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 Adolphe André Lutéreau, 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 (and accompanying Drawings), (that is to say):-
The difficulty found of leaving parts of a given stuff unglazed is by the
present Invention entirely removed, and by its means any reserve can be made
according to the design which is to be applied. The machine used for this
purpose is composed as follows:-
Fig. 1, two rollers between which the piece passes. The roller A is of
hollow cast iron, and is used heated. The roller B, Fig. 2, is of massive cast
iron with the proposed drawing in relief upon it. On the roller A is cog work
of a smaller diameter than the roller governing the wheel placed on the
roller B of a larger diameter than the above-named roller. The roller A may
be governed by any motive power, and, in turn, gives movement to the roller
B by means of its cog work. The roller turns a great deal quicker than
the roller B, this occasioning a sliding movement producing a certain amount
of friction. The roller A turning a great deal quicker than the roller B
slides on the piece P, and by means of a certain heat and a heavy pressure
gives to the substance acted upon a bright gloss. The hollow parts of the
roller not transmitting any pressure to the material allows it to remain in its
natural state, but the pressure of the parts in relief combined with the heat
and friction gives the desired gloss. The process of glazing materials in
relief is of great importance, being very cheap either by drawing or
engraving.
The Inventor reserves to himself the entire right of using the roller as a
new system of engraving, as also the application of cylinder friction.
In witness whereof, I, the said Adolphe André Lutéreau, have hereunto
set my hand and seal, this Sixth day of October, in the year of our
Lord One thousand eight hundred and fifty-eight.
ANDRE LUTEREAU. (L.S.)
