page_text: LETTERS PATENT to John Gough, of 42, Kerby Street, Hatton
Garden, in the County of Middlesex, Engineer, for the Invention
of "IMPROVED GEERING FOR ACTUATING THE KNIFE IN PAPER-CUTTING
MACHINES."
Sealed the 28th October 1868, and dated the 30th April 1868.
PROVISIONAL SPECIFICATION left by the said John Gough at the
Office of the Commissioners of Patents, with his Petition, on the
30th April 1868.
I, JOHN GOUGH, of 42, Kerby Street, Hatton Garden; in the County
of Middlesex, Engineer, do hereby declare the nature of the said
Invention for "IMPROVED GEERING FOR ACTUATING THE KNIFE IN PAPER-
CUTTING MACHINES," to be as follows:-
My said Invention. for "Improved Geering for Actuating the Knife
in Paper-cutting Machines" is. specially applicable to that class of
machines known as Wilson's No. 8353, and dated 21 January 1840,
in which the first motion shaft requires to be reversed to bring back
the knife. In this class of machines the knife frame is now actuated

page_text: by a wheel and pinion, which geering into one another also gcer
into corresponding toothed racks fixed opposite to one another on the
inside of the lower portion of the said frame. I dispense with the
said racks and I actuate this frame (to which the knife is attached)
by means of a crank, the pin of which I fix in the side of the said
wheel. The motion of this pin is transmitted to the knife frame by
means of a connecting rod, the lower extremity of which engages a
pin fixed in the lower extremity of the said frame.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said John Gough in the Great Seal Patent Office on
the 28th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GOUGH, of 42, Kirby Street, Hatton Garden, in the County of
Middlesex, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of April, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Gough, Her special licence that
I, the said John Gough, my executors, administrators, and assigns, or
such others as I, the said John Gough, 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 "IMPROVED GEARING FOR ACTUATING
THE KNIFE IN PAPER-CUTTING MACHINES," upon the condition (amongst
others) that I, the said John Gough, my executors or administrators,
by an instrument in writing, under my, 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.

page_text: NOW KNOW YE, that I, the said John Gough, 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 :-
My said Invention consists of improved gearing for actuating the
knife in paper-cutting machines, and is specially applicable to that
class of machines known as Wilson's (No. 8353, A.D. 1840) in which
the first motion shaft requires to be reversed in order to bring back
the knife. In this class of paper-cutting machines the diagonal frame
to which the knife is attached is now actuated by a pinion fast on the
second motion shaft of the machine, this pinion is caused to gear with
two toothed racks fixed opposite to one another on the interior of
the lower portion of the said diagonal frame, into one rack it gears
directly and into the other through the medium of a toothed wheel
mounted on a stud fixed in the frame of the machine. I dispense
with these toothed racks and I give the required motion to the said
frame by means of a crank on the said stud, the pin of which crank
I prefer to fix in the side of the said toothed wheel on the said stud.
The motion of the said crank I prefer to transmit to the said diagonal
frame through the medium of a connecting rod.
In the accompanying Drawing I have shewn the application of my
Invention to a paper-cutting machine of that class to which it is
specially applicable.
Fig. 1 represents a front elevation of the machine partly in section;
Fig. 2 represents a side elevation of the machine also partly in
section. Similar letters of reference denote the same parts in each
view of the machine. Paper-cutting machines consist principally of
the table for supporting the paper or like substance to be cut, the
gauges for adjusting the paper or like substance to be cut correctly
underneath the knife, the vice for securing the paper while being cut,
the knife and frame to which it is attached, the gearing or mechanism
for giving the required motion to the knife frame; lastly, the gearing
or mechanism employed to transmit, regulate, and control the motive
power employed to actuate the machine.
In the accompanying Drawing a represents the table for giving
support to the paper or like substance-while being cut; b, the knife;
and c, the diagonal frame to which it is attached, and which frame is
free to move up or down in the guides d and e formed in the

page_text: framework of the machine; g represents a pin fixed in the lower
portion of the diagonal frame c, which pin can be adjusted as to
position by means of the screw h and made secure by means of the
nuti; denotes a rod by means of which the said pin g is connected
with the crank pin l, which is shewn fixed in the side of the toothed!
wheel m, which wheel is mounted on the stud n which is supported
at o and p in the frame f of the 'machine; q represents a pinion which
gears into the said toothed wheel m and which is fixed on the second
motion shaft, which is carried in the bearings & and in the frame f
of the machine; next the bearings a large toothed wheel is fixed,
which gears into a pinion v fixed on the first motion shaft wo, this
shaft is carried in the bearings x, y, and z, formed in the frame ƒ of the
machine. a, b, represent a pair of pulleys (fast and loose); c, a
driving belt; d, a sliding bar furnished with a handle e¹ for shifting
the said belt c' on the pulleys a¹ and 6'. The toothed racks with which
I dispense are attached to the machine frame fat f¹ and g¹.
The mode of operation is as follows:-The paper or substance to be
cut having been placed on the table a, adjusted. and secured, the belt
is shifted to the fast pulley by means of the sliding bar d, this causes
the rotation of the first motion shaft w, which is transmitted to the
toothed wheel m; through the medium of the pinion the wheel u,
the shaft r, and the pinion Q, which latter gears into the wheel m
on the stud n in the side of which wheel the crank pin is fixed,
which being connected with the diagonal frame c through the medium
of the connecting rod k and the pin g gives the required motion to the
said frame together with the knife p. Thus it will be perceived that
the action of the machine becomes continuous and the first motion
shaft does not require to be reversed as at present is the case is this
class of machines.
Having thus described the nature of my said Invention, and the
mode of performing the same, I would have it understood that I do
confine myself to the exact details I have described, but what I claim
is, dispensing with the toothed racks in the class of paper-cutting
machines described, and giving the required motion to the diagonal
frame to which the knife is attached by means of a crank, the
pin of which I prefer to fix directly in the side of the toothed wheel
now mounted in these machines on a stud fixed in the frame of the
machine, and transmitting the motion of the said crank to the diagonal

page_text: frame through the medium of a connecting rod or an equivalent
mechanism.
In witness whereof, I, the said John Gough, have hereunto set
my hand and seal, this Twenty-eighth day of October, in
the year of our Lord One thousand eight hundred and sixty-
eight.
