I, JAMES CHADWICK, of Castleton Print Works, near Rochdale, in the
County of Lancaster, Manager, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE APPLICATION OF CERTAIN WOVEN FABRICS TO
PRINTING PURPOSES," to be as follows:-

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
CHADWICK, of Castleton Print Works, near Rochdale, in the County of
Lancaster, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of July, 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 me,
the said James Chadwick, Her special licence that I, the said James Chad-
wick, my executors, administrators, and assigns, or such others as I, the said
James Chadwick, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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
THE APPLICATION OF CERTAIN WOVEN FABRICS TO PRINTING PURPOSES," upon the
condition (amongst others) that I, the said James Chadwick, by an instru-
ment 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 James Chadwick, 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):-
I take what is generally known as woollen bunting or other suitable woollen
woven fabric, and by means of dissolved caoutchouc or other suitable cement
I attach or unite two or more folds of the said fabric together, and if desirable
I introduce a layer of cotton, linen, or a mixture of cotton, linen, and wool, or
similar materials, between the folds of the woollen cloths to strengthen them,
and I thus make a woollen waterproof fabric, or a waterproof fabric made of a
mixture of wool, cotton, or linen, suitable for printing purposes, and intended
to be used for what are generally termed "back cloths," for machine printing,
and can be used with blankets and greys or not, which fabric or fabrics can be

page_text: washed continuously, and dried after each passage from and before its return
to the machine.
Having thus fully described the nature of my said Invention, and the
manner in which the same is to be performed, I desire it to be distinctly
understood that I do not confine myself to the precise details herein set forth,
as such may be varied or modified without departing from the principle thereof;
but I claim as my Invention, and which to the best of my knowledge and
belief has not been hitherto used within the realm, the uniting two woollen
fabrics together with caoutchouc or other suitable cement to make the same
waterproof, and strengthen it by the addition of cotton or linen, or a mixture
thereof with wool, and the application of the said fabric or fabrics to printing
purposes.
In witness whereof, I, the said James Chadwick, have hereunto set
my hand and seal, this Nineteenth day of January, in the year of
our Lord One thousand eight hundred and fifty-nine.
JAMES CHADWICK. (L.S.)
Signed, sealed, and delivered by the within-
named James Chadwick, in the presence of
E. J. HUGHES, Patent Agent,
Manchester.
