IMPROVEMENTS IN CUTTING PRESSES EMPLOYED IN THE MANUFACTURE OF BOOTS, SHOES, ENVELOPES, PAPER COLLARS, AND VARIOUS OTHER ARTICLES
Year: 1866

page_text: LETTERS PATENT to James Charles Patrick, Engineer and Machinist,
of Aylesbury Street, Clerkenwell, in the County of Middlesex, for the
Invention of "IMPROVEMENTS IN CUTTING PRESSES EMPLOYED IN THE
MANUFACTURE OF BOOTS, SHOES, ENVELOPES, PAPER COLLARS, AND VARIOUS
OTHER ARTICLES."
Sealed the 31st July 1866, and dated the 2nd February 1866.
PROVISIONAL SPECIFICATION left by the said James Charles Patrick
at the Office of the Commissioners of Patents, with his Petition, on
the 2nd February 1866.
I, JANES CHARLES PATRICK, Engineer and Machinist, of Aylesbury Street,
Clerkenwell, in the County of Middlesex, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN CUTTING PRESSES EMPLOYED IN THE
MANUFACTURE OF BOOTS, SHOES, ENVELOPES, PAPER COLLARS, AND VARIOUS OTHER
ARTICLES," to be as follows, that is to say:-
The object of this Invention is to obtain greater simplicity in the construc-
tion of cutting presses used in the manufacture of boots, shoes, envelopes, and
other articles, and likewise a considerable increase of power. To effect this I
erect two side frames or standards extending above a stationary bed plate
fixed between them; slots are formed in the said standards to admit and

page_text: act as guides to the bearings of a second or moveable press or plate, which is
made to move up and down the said slots by means of rods and eccentrics.
These rods are also formed with slots or grooves at one end, through which
the bearings of the moveable or cutting plate are passed, the other ends being
attached to an eccentric or cam shaft running horizontally through the press,
the cams being on the outside, and as the eccentric revolves the moveable
plate is raised and lowered thereby, and by this means I obtain greater
freedom of action, less friction, and a considerable increase of power. For
setting the moveable plate to the desired elevation or depression I place a
spiral or other spring under its bearings, and fix it to the greatest nicity by
a set screw (turned by a spanner or otherwise) passed through the top and
impinging on the said bearings.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Charles Patrick in the Great Seal Patent Office on
the 2nd August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
CHARLES PATRICK, of Aylesbury Street, Clerkenwell, in the County of
Middlesex, Engineer and Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of February, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said James Charles Patrick, Her special licence that I, the said
James Charles Patrick, my executors, administrators, and assigns, or such
others as I, the said James Charles Patrick, 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 "IMPROVEMENTS IN CUTTING PRESSES EMPLOYED IN
THE MANUFACTURE OF BOOTS, SHOES, ENVELOPES, PAPER COLLARS, AND VARIOUS OTHER
ARTICLES," upon the condition (amongst others) that I, the said James Charles
Patrick, my executors or administrators, by an instrument in writing under
I, 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 saine
was to be performed, and cause the same to be filed in the Great Seal Patent

page_text: Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said James Charles Patrick, 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:
The object of this Invention is to obtain greater simplicity in the con-
struction of cutting presses employed in the manufacture of boots, shoes,
envelopes, paper collars, and other similar articles, and likewise a considerable
increase of power therefor. To effect this I erect two side frames or standards
extending above a stationary bed plate or table which is fixed between them;
slots are formed in these standards to admit the bearings of a second or
moveable plate, which is made to move up and down the said slots (by which
it is guided) by means of rods and eccentrics or cams; these rods have slots
formed at one end through which the bearings of the moveable plate are
passed. The other ends of the rods are attached on either side to eccentrics
or cams (the shaft of which passes horizontally through the machine), which
are placed outside the frame, and as the eccentrics or cams are made to
revolve by any suitable mechanism, either by hand or steam, the moveable
plate is thereby raised and lowered. For setting this moveable plate to any
desired elevation or depression I place a spiral or other spring below the
bearing thereof in the slots formed in the connecting rods, through the tops
of which I pass set screws for setting the same, which screws are turned
when desired by a spanner, gear motion, or otherwise, as found convenient
for fixing the cutting or stamping plate in the required position.
I claim generally the machine as herein described, but more particularly
the use of cams or eccentrics and connecting rods for giving a direct motion
to the moveable or cutting plate.
In witness whereof, I, the said James Charles Patrick, have hereunto
set my hand and seal, this Second day of August, in the year of our
Lord One thousand eight hundred and sixty-six.
JAMES CHARLES PATRICK. (L.B.)
