page_text: LETTERS PATENT to Alexander Browne, of the Firm of Browne and
Company, Patent Agents, of 5, Southampton Buildings, Holborn, in
the County of Middlesex, for the Invention of "AN IMPROVED
MACHINE FOR CUTTING PAPER AND OTHER MATERIALS."-A communication
from abroad by Emile Truchot, trading under the name of Paul
PROVISIONAL SPECIFICATION left by the said Alexander Browne
at the Office of the Commissioners of Patents, with his Petition,
on the 19th June 1874.
I, ALEXANDER BROWNE, of the Firm of Browne and Company, Patent
Agents, of 5, Southampton Buildings, Holborn, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"AN IMPROVED MACHINE FOR CUTTING PAPER AND OTHER MATERIALS," a com-
munication from abroad by Emlie Truchot, trading under the name
of Paul Truchot, of Paris, in the French Republic, Merchant, to be
as follows:
This Invention relates to an improved machine for cutting paper and

page_text: The principle on which this Invention is based consists in giving to
the knife or blade a parallel reciprocating motion, that is to say, a
motion similar to that of the connecting rods of locomotive engines,
whereby great simplicity and power is obtained.
The machines constructed according to this principle may vary in
shape and arrangement, but the principle will be the same, i. e., a straight
knife or blade fixed excentrically at each of its extremities to one or
between two discs or toothed wheels, to which a rotary motion is given
by a worm or otherwise, or by any suitable combination of mechanical
parts receiving a rotary motion which will bring down the knife and
make it describe the arc of a circle. The knife may begin to act or cut
when it reaches the horizontal line which passes by the axis of the
wheels or pair of wheels to which it is fixed.
When a continuous rotary motion is applied to the driving shaft the
knife begins to rise when its fixed points have passed the vertical centre
line of the wheels and descends again when those points have passed
over the top of the said line.
In order to bring the knife up again a continuous motion may be
given to the wheels by the driving shaft, as above described, or else a
return motion is given thereto, in which case it will be necessary only
to have teeth on half the circumference of the wheels.
And in order to explain this Invention more fully reference is had to
the illustrative Sheets of Drawings accompanying this Specification, and
to the numeral figures and letters of reference marked thereon respec-
tively, as follows:-
:―
Figure 1 is a front section view of the machine; Figure 2, an end
view of the same. In these two Figures similar letters are used to denote
corresponding parts.
a is the bed of the machine, which may be of any suitable shape; b, b¹,
supports bolted to the table a; c, c¹, c, c¹, are toothed wheels which
revolve on the spindles d, d', fixed to the supports 6, 6¹; e is a blade or
knife fixed at fat each of its extremities on or between two equal sized
wheels, by which means the knife will not have a tendency to deviate
when cutting; g, driving shaft passing through the supports b, b';

Office on the 19th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
BROWNE, of the Firm of Browne and Company, Patent Agents, of 5,
Southampton Buildings, Holborn, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of June, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alexander Browne, Her special
licence that I, the said Alexander Browne, my executors, admini-
strators, and assigns, or such others as I, the said Alexander Browne,
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
"AN IMPROVED MACHINE FOR CUTTING PAPER AND OTHER MATERIALS," a
communication from abroad by Emile Truchot, trading under the
name of Paul Truchot, of Paris, in the French Republic, Merchant,
upon the condition (amongst others) that I, the said Alexander Browne,
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 imme-
diately after the date of the said Letters Patent,

page_text: NOW KNOW YE, that I, the said Alexander Browne, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say :-
This Invention relates to an improved machine for cutting paper and
other materials.
The principle on which this Invention is based consists in giving to
the knife or blade a parallel reciprocating motion, that is to say, a
motion similar to that of the connecting rods of locomotive engines,
whereby great simplicity and power is obtained.
The machines constructed according to this principle may vary in
shape and arrangement but the principle will be the same, i.e., a straight
knife or blade fixed eccentrically at each of its extremities to one or
between two discs or toothed wheels, to which a rotary motion is given
by a worm or otherwise, or by any suitable combination of mechanical
parts receiving a rotary motion which will bring down the knife and
make it describe the arc of a circle. The knife may begin to act or cut
when it reaches the horizontal line which passes by the axis of the
wheels or pair of wheels to which it is fixed.
When a continuous rotary motion is applied to the driving shaft the
knife begins to rise when its fixed points have passed the vertical centre
line of the wheels and descends again when those points have passed
over the top of the said line.
In order to bring the knife up again a continuous motion may be
given to the wheels by the driving shaft, as above described, or else a
return motion is given thereto, in which case it will be necessary only
to have teeth on half the circumference of the wheels.

DESCRIPTION OF THE DRAWINGS.

page_text: a is the bed of the machine, which may be of any suitable shape; b, b',
supports bolted to the table a; c, c¹, c, c¹, are toothed wheels, which
revolve on the spindles d, d', fixed to the supports b, b¹; e is a blade or
knife fixed at f, at each of its extremities, on or between two equal sized
wheels, by which means the knife will not have a tendency to deviate
when cutting; g, driving shaft passing through the supports b, b₁; h,
fly wheel keyed at one end of the shaft g; i, square part on the shaft g,
on which is placed a winch handle; j, worms keyed on the shaft g, and
gearing at the same time with the two equal sized wheels c, c¹, as shown
at Figure 2; k, bed on which is placed the paper to be cut, or other
material; m, press for pressing down the paper; n, screw, by means of
which pressure is given to the press m.

Having now described and set forth the nature and object of this
Invention for "An Improved Machine for Cutting Paper and other
Materials I would remark in conclusion that I hereby declare this
Invention to consist in and I claim, applying to the blades or knives of
machines for cutting paper or other materials a parallel reciprocating
motion similar to that of the connecting rods of locomotive engines,
substantially as described and represented.
In witness whereof, I, the said Alexander Browne, have hereunto
set my hand and seal, this Nineteenth day of December, in the
year of our Lord One thousand eight hundred and seventy-
four.
