page_text: LETTERS PATENT to Thomas Hargreaves Taylor of the City of Manchester
in the County of Lancaster for an Invention of "IMPROVEMENTS IN APPARATUS
'FOR PRODUCING FAC-SIMILE COPIES OF WRITINGS, DRAWINGS FIGURES AND
ACCOUNTS"
PROVISIONAL SPECIFICATION left by the said Thomas Hargreaves Taylor
at the Office of the Commissioners of Patents on the 4th August 1882.
THOMAS HARGREAVES TAYLOR, of the City of Manchester, in the County of
Lancaster "IMPROVEMENTS IN APPARATUS FOR PRODUCING FACSIMILE COPIES
OF WRITINGS, DRAWINGS, FIGURES, AND ACCOUNTS."
This invention consists in the employment of two wooden frames or boards, one
or both being recessed in the interior, and saturated with waterproofing matter,
and each recess contains a sheet of waterproof cloth, these boards being either loose,
or hinged together, as may be required.
Between the boards I place two or more cushions, each consisting of an endless
sheet of fine pure calico, having in its interior a sheet or layer of felt covered with.
a sheet or sheets of French flannel of the same or different densities, and on one
side of each cushion is placed a border or diaphragm of thin sheet metal or water-
proof material, which folds over the transfer sheet before the copy is impressed
upon it, and also keeps the negative or sheet from which the copy is taken exactly
in its place. The cushions are used separately or joined together at one of their
sides, and the cushions are damped or moistened with water according to the
number of originals required to be copied, thereby enabling the copyist when the
apparatus is pressed by a lever or screw press to take copies of the same or different
writings, drawings, figures or accounts, at one and the same time as may be
required, according to the number of sheets to be copied, and the number of
damped cushions; and between each series or set of cushions I place a metallic
plate or sheet of waterproof material to assist in the development of each set of
copies.

Having thus particularly described and ascertained the nature of my said Inven-
tion, together with the best methods with which I am acquainted for carrying the
same into practical effect, I desire it to be understood that I claim.
The improved copying and reproducing process substantially as herein before
described.
In witness whereof I the said Thomas Hargreaves Taylor have hereunto set
my hand and seal this thirty-first day of January in the year of our Lord
one thousand eight hundred and eighty three.
