page_text: LETTERS PATENT to Robert Ellis Green, of Accrington, in the County of
Lancaster, Turkey Red Dyer, and John Cockcroft, of the same Place,
Machine Printer, for the Invention of "AN IMPROVED AMALGAMATION
OF MATERIALS FORMING A SUBSTANCE SUITABLE FOR PRINTERS' BLANKETS,
CONDUCTORS USED IN PAPER-MAKING, PACKINGS FOR JOINTS, AND

Sealed the 6th April 1863, and dated the 10th October 1862.
PROVISIONAL SPECIFICATION left by the said Robert Ellis Green and
John Cockcroft at the Office of the Commissioners of Patents, with
their Petition, on the 10th October 1862.
We, ROBERT ELLIS GREEN, of Accrington, in the County of Lancaster,
Turkey Red Dyer, and JOHN COCKCROFT, of the same Place, Machine Printer,
do hereby declare the nature of the said Invention for "AN IMPROVED AMAL-
GAMATION OF MATERIALS FORMING A SUBSTANCE SUITABLE FOR PRINTERS' BLANKETS,
CONDUCTORS USED IN PAPER-MAKING, PACKINGS FOR JOINTS, AND SIMILAR PURPOSES,"
to be as follows:-
We take webs of paper and apply to one side of them a solution of india-
rubber, and then join two or more of the said webs in such a manner that
they adhere together leaving the dry sides of the paper outside. Or we
prepare a textile fabric, such as linen, strong calico, or woollen, in the same
manner and join a web of the prepared paper to it, so as to leave cloth on
one side and paper on the other. Or we make a compound web with a sheet
of cloth in the middle, and paper-on each side which substances when dried.

page_text: are suitable for printers' blankets, webs used in paper-making, and similar
purposes.
To make washers or packings for joints we form any suitable number of
the said prepared webs together, and submit-them to pressure and a drying
process, we then stamp or cut out washers or packings the required size and
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of October, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Robert Ellis Green and John Cockcroft, Her special license that we, the
said Robert Ellis Green and John Cockcroft, our executors, administrators, and
assigns, or such others as we, the said Robert Ellis Green and John Cockcroft,
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 AMALGAMATION
OF MATERIALS FORMING A SUBSTANCE SUITABLE FOR PRINTERS' BLANKETS, CON-
DUCTORS USED IN PAPER-MAKING, PACKINGS FOR JOINTS AND SIMILAR PURPOSES,"
upon the condition (amongst others) that we, the' said Robert Ellis Green
and John Cockcroft, our executors or administrators, by an instrument in
writing under 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 Robert Ellis Green and John Cockcroft,
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);-
4

page_text: We combine two or more lengths of paper together with a solution of india-
rubber or its substitutes by spreading it between them and pressing them
together. Or we put a textile fabric such as linen, cotton, or woollen between
folds of paper, or we put a textile fabric such as linen, cotton, or woollen on
the outside with paper underneath, always making the different folds adhere
with a solution of india-rubber or its substitutes as above.
In selecting the "surface" for the article to be used for printers' blankets
it must be adapted to the peculiar colors used by the printer, as some, colors
are strongly acid, some alkaline, and others neutral.
For the webs used by paper makers we prefer to use folds of woollen paper
with a textile fabric at the back..
For washers of packing for steam joints we join any suitable number of
any of the above materials together and submit them to pressure and heat or
other drying process.
Having now described the nature and particulars of our said Invention, and
the manner in which the same is to be performed, we desire it to be under-
stood that we claim the application of a solution of india-rubber or its
substitute to paper alone or in combination with textile fabrics in the manner
and for the purposes herein described.
In witness whereof, I, the said Robert Ellis Green, for and on behalf of
myself and the said John Cockcroft, have hereunto set my hand and
seal, this Fourth day of April, in the year of our Lord One thousand
eight hundred and sixty-three.
Signed, sealed, and delivered by the within-
named Robert Ellis Green, in the
presence of
