AN IMPROVED PROCESS OF ORNAMENTING SEAL SKIN CLOTHS
Year: 1868

page_text: LETTERS PATENT to Henry Dewhurst, John William Dewhurst,
and Robert Ellis Dewhurst, members of the Firm of Richard
Dewhurst and Company, of the Aspley Print Works, near Hudders-
field, in the County of York, Woollen and Stuff Printers, for the
Invention of "AN IMPROVED PROCESS OF ORNAMENTING SEAL SKIN
CLOTHS."
Sealed the 24th November 1868, and dated the 12th August 1868.
PROVISIONAL SPECIFICATION left by the said Henry Dewhurst,
John William Dewhurst, and Robert Ellis Dewhurst at the Office
of the Commissioners of Patents, with their Petition, on the 12th
August 1868.
We, HENRY DEWHURST, JOHN WILLIAM DEWHURST, and ROBERT
ELLIS DEWHURST, members of the Firm of Richard Dewhurst and
Company, of the Aspley Print Works, near Huddersfield, in the County
of York, Woollen and Stuff Printers, do hereby declare the nature of
the said Invention for "AN IMPROVED PROCESS OF ORNAMENTING SEAL SKIN
CLOTHS," to be as follows:-
The Invention relates to the production of what are known as painted
seal skin cloths of any width by mechanical means, such cloths having
hitherto been only produced either by hand or by block printing or by

page_text: sprinkling from a brush filled with paint, the latter producing simply
a mottled or "pepper and salt" effect.
By the use of a modification of the ordinary cylinder printing machine
and process as employed for printing calicoes and other similar fabrics
we are enabled to apply the paint to the surface of the seal skin cloth
in a much more economical and effectual manner, and to produce a
variety of patterns, designs, or other effects which could not be obtained
by hand or in any other known way, and which possess greater accuracy,
uniformity, delicacy, and finish than any other painted seal skin cloths
now or hitherto in the market.
In carrying out this Invention we take a plain copper or other
cylinder or roller and engrave the surface in such a manner as to
produce either uniform tipping or coloring or tipping or coloring in the
desired pattern or design, and having mounted this roller, so engraved,
in a cylinder printing machine we apply paint to the surface of the said
roller (instead of the colors ordinarily employed for cylinder printing) in
the same manner and by the same means as the color is usually furnished
to printing rollers, such paint being transferred by the cylinder to the
seal skin cloth as it passes through the machine in contact therewith.
What are called "diagonals" or "diagonal patterns" or "stripes"
or "striped patterns" may be produced in this way with very great
effect.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Dewhurst, John William Dewhurst, and
Robert Ellis Dewhurst in the Great Seal Patent Office on the 2
28th January 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
DEWHURST, JOHN WILLIAM DEWHURST, and ROBERT ELLIS DEWHURST,
Members of the Firm of "Richard Dewhurst and Company," of the
Aspley Print Works, in the Borough of Huddersfield, in the County of a
York, Woollen and Stuff Printers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of August, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Henry Dewhurst, John William Dewhurst,

page_text: and Robert Ellis Dewhurst, Her special licence that we, the said
Henry Dewhurst, John William Dewhurst, and Robert Ellis Dewhurst,
our executors, administrators, and assigns, or such others as we, the
said Henry Dewhurst, John William Dewhurst, and Robert Ellis
Dewhurst, our 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
"AN IMPROVED PROCESS OF ORNAMENTING SEAL SKIN CLOTHS," upon the
condition (amongst others) that we, the said Henry Dewhurst, John
William Dewhurst, and Robert Ellis Dewhurst, our executors. or ad-
ministrators, by an instrument in writing under our, or one of our,
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 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 we, the said Henry Dewhurst, John William
Dewhurst, and Robert Ellis Dewhurst, do hereby declare the nature of
our said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following
statement in writing, that is to say :-
.
This Invention relates to the production of what are known as painted
seal skin cloths of any width by mechanical means, such cloths having
bitherto been only produced either by hand or by block printing, or by
sprinkling from a brush filled with paint, the latter producing simply
a mottled or "pepper and salt" effect.
By the use of a modification of the ordinary cylinder printing machine
and process as employed for printing calicoes and other similar fabrics
we are enabled to apply the paint to the surface of the seal skin cloth in
a much more economical and effectual manner than hitherto, and to
produce a variety of patterns, designs, or other effects which could not
be obtained by hand or in any other known way, and which possess
greater accuracy, uniformity, delicacy, and finish than any other painted
seal skin cloths now or hitherto in the market.
Such being the nature and object of our said Invention for "An
Improved Process of Ornamenting Seal Skin Cloths," we will now
proceed to describe more in detail the manner in which the same is to be

page_text: or may be performed or carried into practical effect, which will be readily
understood on reference to the following explanation thereof, that is to
say:―
In carrying out this Invention we take a plain copper or other
cylinder or roller and engrave the surface in such a manner as to
produce either uniform tipping or coloring, or tipping or coloring in
the desired pattern or design, and having mounted this roller (so
engraved) in a cylinder printing machine, we apply paint to the surface
of the said roller (instead of the colors ordinarily employed for cylinder
printing) in the same manner and by the same means as the color is
usually furnished to printing rollers, such paint being transferred by the
cylinder to the seal skin cloth as it passes through the machine in
contact therewith. What are called "diagonals," or "diagonal patterns,"
or "stripes," or striped patterns" may be produced in this way with
very great effect.
<
Having now described the nature and object of our said Invention
for "An Improved Process of Ornamenting Seal Skin Cloths," together.
with the manner in which the same is to be or may be performed or carried
into practical effect, we would remark in conclusion that we claim as
our Invention, the improved process of or for ornamenting or painting seal
skin cloths, substantially as herein-before described, or any mere modifi-
cation of such process operated in the same or a similar manner.
In witness whereof, we, the said Henry Dewhurst, and John
William Dewhurst, have hereunto set our hands and seals, this
Eighth day of January, in the year of our Lord One thousand
eight hundred and sixty-nine.
HENRY DEWHURST.
