Year: 1858

page_text: LETTERS PATENT to Joseph Walker and James Barnes, of Oakenshaw,
in the County of Lancaster, Waterproof Cloth Manufacturers, for the
Invention of "IMPROVEMENTS IN BLANKETS AND LAPPINGS FOR MACHINE AND
BLOCK PRINTING, AND OTHER SIMILAR PURPOSES."
Şealed the 25th February 1859, and dated the 2nd September 1858. .
PROVISIONAL SPECIFICATION left by the said Joseph Walker and James.
Barnes at the Office of the Commissioners of Patents, with their Petition,
on the 2nd September 1858.
We, JOSEPH WALKER and JAMES BARNES, of Oakenshaw, in the County of
Lancaster, Waterproof Cloth Manufacturers, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN BLANKETS AND LAPPINGS FOR-
MACHINE AND BLOCK PRINTING, AND OTHER SIMILAR PURPOSES," to be as
follows:-
This Invention relates to the application and use to and in the processes of
machine and block printing of an improved blanket or lapping, to be sub-
stituted for the ordinary blanket, felt, or other lapping ordinarily employed upon
printing machines and tables. The improvements consist essentially in the
application and use of a cotton pile surface. In making blankets or lappings
according to this Invention, two or more thicknesses of cotton fabric are
cemented together by india-rubber solution or other waterproof cement the
outer or pressing surface of the combined fabric having a pile raised thereon
by any of the well-known methods adopted for pile raising.

by the said Joseph Walker and James Barnes in the Great Seal Patent
Office on the 1st March 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
WALKER and JAMES BARNES, of Oakenshaw, in the County of Lancaster,
Waterproof-Cloth Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of September, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Joseph Walker and James Barnes, Her special license that we,
the said Joseph Walker and James Barnes, our executors, administrators, and
assigns, or such others as we, the said Joseph Walker and James Barnes,
our executors, administrators, or 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 BLANKETS AND
LAPPINGS FOR MACHINE AND BLOCK PRINTING, AND OTHER SIMILAR PURPOSES,"
upon the condition (amongst others) that we, the said Joseph Walker
and James Barnes, by an instrument in writing under our 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 Joseph Walker and James Barnes,
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, that is to say:-
Our said Invention relates to the application and use to and in the processes
of machine and block printing of an improved blanket or lapping, to be sub-
stituted for the ordinary blanket, felt, or other lapping usually employed in.
printing machines and tables. According to this Invention we propose to
employ a blanket or lapping having a cotton pile-pressing surface in lieu of
the ordinary plain cotton surfaces hitherto used. These improved blankets
or lappings may be constructed by cementing together by means of india-
rubber solution or other waterproof cement, two or more thicknesses of cotton
fabric, the outer or pressing surface of such combined fabric having a pile

page_text: raised thereon by any of the well-known methods adopted for pile raising.
We do not confine ourselves to any particular mode of constructing or
applying the blanket, so long as the main feature of our Invention be adhered
to, namely, the use of a cotton pile or raised surface formed on a cotton
blanket.
The chief advantage to be derived from the use of pile surface blankets in
machine and block printing is increased elasticity in the direction of the
thickness of the blanket, whereby a more yielding and even pressure is
distributed over the surface of the "form."
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion that we do not confine or restrict
ourselves to the precise details or arrangements which we have had occasion
to describe or refer to, as variations may be made therefrom without deviating
from the principles or main features of our said Invention; but what we
consider to be novel and original, and therefore claim as the Invention secured
to us by the herein-before in part recited Letters Patent is,-
First, the general construction of blankets or lappings for printing purposes
as herein-before described.
Second, the application and use to and for printing processes of a blanket
or lapping, having a cotton pile or raised cotton face formed on the pressing
surface, as herein-before described.
In witness whereof, we, the said Joseph Walker and James Barnes, have
hereunto set our hands and seals, the Twenty-eighth day of February,
in the year of our Lord One thousand eight hundred and fifty-nine.
