Year: 1861

page_text: LETTERS PATENT to William Mitchell, of the City of Manchester, in
the County of Lancaster, Paper Hanging Manufacturer, for the Inven-
tion of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PRINTING PAPER
HANGINGS."
Sealed the 12th November 1861, and dated the 15th May 1861.
PROVISIONAL SPECIFICATION left by the said William Mitchell at the
Office of the Commissioners of Patents, with his Petition, on the 15th
May 1861.
I, WILLIAM MITCHELL, of the City of Manchester, in the County of
Lancaster, Paper Hanging Manufacturer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PRINTING
PAPER HANGINGS," to be as follows:-
This Invention consists in employing in connection with each printing roller
an additional roller covered with flannel, india-rubber, or other suitable
material, for the purpose of guiding the paper to be printed over a much
larger portion of the circumference of the printing roller than is at present
obtained. The said additional roller is pressed against the printing roller by
screws or other means, and enables the paper to be of sufficient time on the
surface of the printing roller to absorb effectually the color with which the
paper is to be printed.

by the said William Mitchell in the Great Seal Patent Office on the
15th November 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MITCHELL, of the City of Manchester, in the County of Lancaster, Paper
Hanging Manufacturer, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of May, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Mitchell, Her special licence that I, the said William Mitchell, my
executors, administrators, and assigns, or such others as I, the said William
Mitchell, 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 MACHINERY
OR APPARATUS FOR PRINTING PAPER HANGINGS," upon the condition (amongst
others) that I, the said William Mitchell, 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 Inven
tion, 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 William Mitchell, 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 fol-
lowing statement, that is to say) :-
:-
This Invention consists in employing in connection with each printing roller
an additional roller covered with flannel, india-rubber, or other suitable
material, for the purpose of guiding the material to be printed over a much
larger portion of the circumference of the printing roller than is at present
obtained. The said additional roller is pressed against the printing foller by
screws or other means, and enables the paper to be a sufficient time on the
surface of the printing roller to absorb effectually the color with which the
paper is to be printed.
These improvements will be clearly understood by reference to the accom-

page_text: panying Drawing, representing a transverse section of the rollers of a two-
color printing machine, having my additional rollers applied to it.
The paper to be printed is shewn at a, it is guided by the guide rollers 6 to
the first additional roller c in connection with the printing roller d, from
whence the paper passes to the second printing roller e, and under the second
additional roller f, and then led onwards as desired. Each additional roller in
the figure is so placed as to cause the printing roller in connection with it to
be covered with paper for about half of its circumference; but these positions
may be varied according to the requirements, it being only necessary to have
such an extent of surface as to enable the color to be effectually absorbed.
Having now described the nature and particulars of my said Invention, and
the manner in which the same is to be performed, I desire it to be understood
that I claim in machinery or apparatus for printing paper hangings, the
employment of an additional roller covered with flannel, india-rubber, or other
suitable material in connection with each printing roller, for the purpose of
guiding the paper to be printed over a much larger portion of the cir-
cumference of the printing roller than is at present obtained, as such improve-
ments are herein described and illustrated in the accompanying Drawing.
In witness whereof, I, the said William Mitchell, have hereunto set my
hand and seal, this Thirteenth day of November, in the year of our
Lord One thousand eight hundred and sixty-one.
WILLIAM MITCHELL. (LS.)
Signed, sealed, and delivered, by the
within-named William Mitchell,
in the presence of
