PROVISIONAL SPECIFICATION left by the said Joseph Lease at the
Office of the Commissioners of Patents, with his Petition, on the
8th August 1856.
I, JOSEPH LEESE, jun', of Manchester, in the County of Lancaster, Calico
Printer, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY USED FOR PRINTING CALICO AND OTHER FABRICS," to,
be as follows:-
My Invention consists of the application of scrapers, or what are technically
called "doctors," for the removing the extraneous color deposited by the printing
cylinders upon the bowl itself, or upon the blanket or web of any kind used
for covering the bowl of the printing machine, by which arrangement I save.
color, and simplify the printing machine in many of its parts, as I require only
a very short blanket, or none at all, and thus I do away with part of the frame-
work, and many of the rollers required to carry the blanket. In case I use
blankets or webs of india-rubber, or the bowl itself covered with india-rubber,
I provide a small stream of liquid colour, or liquid of any kind, to fall on the.

protected from injury by the former, the liquid operating as a kind of
lubricator.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Leese in the Great Seal Patent Office on the
28th January 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
LEESE, junior, of Manchester, in the County of Lancaster, Calico Printer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters-
Patent, bearing date the Eighth day of August, in the year of our Lord One
thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself; Her heirs and successors, give and grant unto me, the said
Joseph Leese, Her special license that I, the said Joseph. Leese, my
executors, administrators, and assigns, or such others as -I, the said Joseph
Leese, my 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 "CERTAIN IMPROVEMENTS IN MACHINERY
USED FOR PRINTING CALICO AND OTHER FABRICS," upon the condition (amongst
others) that I, the said Joseph Leese, my executors or administrators, by an
instrument in writing under 'iny, 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
inimediately after the date of the said Letters, Patent.
"NOW' KNOW YE, that I the said Joseph. Leese, do hereby declare the
nature of my said "Invention, and in what manner the same is to be per-
formed; to be particularly described and ascertained in and by the following
statement:
My Invention consists of the application of scrapers, or what are technically
called doctors, for removing the extraneous color deposited by the "printing
cylinders upon the bowl itself, or upon the blanket or net of any kind used for
covering the bowl of the printing machine; by which arrangement I save color,

page_text: and simplify the printing machine in many of its parts, as I require only a very
short blanket, or none at all, and thus I do away with part of the framework,
and many of the rollers required to carry the blanket. Or, instead of applying
the scraper directly to the blanket, I substitute a roller, which I cause to
revolve against the face of the blanket or cylinder in a reverse direction to that
in which the blanket or cylinder moves. I then place the doctor or scraper
upon this roller, and thus recover the color from it instead of from the blanket
direct, as before described. When required, I use a small stream of liquid
color, or liquid of any kind, and cause it to flow in front of the roller or
scraper, so that it may act as a lubricator, and so prevent injury to the bowl
or blanket covering it.
Now, what I claim as my Invention is, the removal and recovery of the
color from the bowl or blanket of the printing machine by the methods as
herein-before described.
In witness whereof, I, the said Joseph Leese, have hereunto set my
hand and seal, this Fifteenth day of January, in the year of our
Lord One thousand eight hundred and fifty-seven.
JOSEPH LEESE, JUNIOR. (L.S.)
Declared at Manchester, in the County of Lancaster,
this Fifteenth day of January, One thousand eight
eight hundred and fifty-seven, before me,
JAMES BARROW,
A Commissioner to Administer Onths in Cheneory in England
