page_text: LETTERS PATENT to Joseph Bartlett, of Middleton Street, Clerkenwell,
in the County of Middlesex, Engraver and Printer, for the Invention
of "IMPROVEMENTS IN PRINTING."
PROVISIONAL SPECIFICATION left by the said Joseph Bartlett at the
Office of the Commissioners of Patents, with his Petition, on the
25th July 1872.
I, JOSEPH BARTLETT, of Middleton Street, Clerkenwell; in the County
of Middlesex, Engraver and Printer, do hereby declare the, nature of
the said Invention for "IMPROVEMENTS IN PRINTING," to be as follows :—
The improvements consist in the manufacture and use of engraved or
countersunk type rendered capable of being set up in shapes, forms, or
chases of any desired shape, size, or form.
Also in the manufacture and use of improved curved shapes, forms,
or chases for holding the improved type aforesaid.
Also in the use and application of the improved type and improved
chases for the purposes of printing.

page_text: Also the transfering the impression of such printing on stone or zinc
or other suitable material, and striking off impressions from the stone
or zinc presenting the appearance of engraved or other like work, and
be superior to and cheaper than the ordinary raised type printing, or to
the lithographing or zincographing at present in use.
The improvements may be performed by making the engraved type
and chases of any suitable and convenient material, and any required
letter, figure, or design may be engraved, impressed, or etched in or
otherwise formed in or upon the said type. The type may be put into
a frame or frames furnished with chases, which may be straight or
curved, or both, or otherwise formed to receive and hold the type in
any desired position for the various designs required. Having thus set
up the type, ink is applied and an impression is struck or printed on
transfer paper; this impression will not only shew all the required
design, but also all the lines or marks of the chases or forms used to
hold the type; it is therefore necessary to erase the chase marks and
leave the design. The impression on transfer paper is then impressed
on stone or zinc in the usual way, and copies are struck off from the
stone or zinc. Or the impression on transfer paper may be impressed on
the stone or zinc without first erasing the chase marks, which may be
erased from off the stone or zinc.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Joseph Bartlett in the Great Seal Patent Office
on the 22nd January 1873.
