PROVEMENTS IN MACHINES FOR CUTTING PAPER, CARD, AND MILLBOARDS, AND
OTHER LIKE SUBSTANCES."
Sealed the 22nd January 1856, and dated the 10th August 1855.
PROVISIONAL SPECIFICATION left by the said Edwin Ullmer and
William Ullmer at the Office of the Commissioners of Patents, with
their Petition, on the 10th August 1855.
We, EDWIN ULLMER and WILLIAM ULLMER, both of Fetter Lane, in the
City of London, Manufacturers, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINES FOR CUTTING PAPER, CARD AND
MILLBOARDS, AND OTHER LIKE SUBSTANCES," to be as follows:-
Our Invention consists in imparting to the knife of paper-cutting machines
a diagonal or draw cut, and also in a means of raising and lowering the knife.
These improvements we effect in the following manner:-One end of the knife
is supported in one angle of a bell-crank lever, which has its fixed centre in
the framework of the machine. The opposite angle to that in which the knife
is supported has pivotted to it the upper end of a connecting rod, the opposite
end of which rod is attached to a crank upon one end of the shaft of the main
spur wheel. A similar rod is attached to the opposite end of the knife, and
is also attached excentrically upon one of the arms of the spur wheel. Both
the connecting rods are divided into two parts, each of which is cut with the
thread of a screw, one a right-handed screw and the other a left-handed
Upon these two parts of the rod is fitted a socket or nut, cut with
interior threads, corresponding to the right and left handed threads upon the
parts of the rod. The knife can be raised or lowered, or set at any required
screw.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWIN
ULLMER and WILLIAM ULLMER, both of Fetter Lane, in the City of London,
Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of August, in the year of our Lord One
thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Edwin Ullmer and William Ullmer, Her special licence that we, the
said Edwin Ullmer and William Ullmer, our executors, administrators, and
assigns, or such others as we, the said Edwin Ullmer and Williamı Ullmer,
our 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 MACHINES FOR
CUTTING PAPER, CARD AND MILLBOARDS, AND OTHER LIKE SUBSTANCES,"
upon the
condition (amongst others) that we, the said Edwin Ullmer and William
Ullmer, or one of us, by an instrument in writing under our hands and seals, or
under the hand and seal of one of us, 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.
NOW KNOW YE, that we, the said Edwin Ullmer and William Ullmer,
do hereby declare the nature of our said Invention, and in what manner the
saine is to be performed, to be particularly described and ascertained in and by
the following statement thereof, reference being had to the Drawings hereunto
annexed, that is to say :--
Our Invention consists in imparting to the knife of paper-cutting
machines a diagonal or draw cut, and also in a means of raising and lower-

page_text: ing the knife. These improvements we effect in the following manner :-
One end of the knife is supported in one angle of a bell crank, which has its
fixed centre in the framework of the machine. The opposite angle to that in
which the knife is supported has pivotted to it the upper end of a connecting
rod, the opposite end of which is attached to a crank upon one end of the
shaft of a main spur wheel. A similar rod is attached to the opposite end of
the knife, and is also attached excentrically upon one of the arms of the spur
wheel, or to a crank formed by a pin and one of the arms of the wheel. Both
the connecting rods are divided into two parts, each of which is cut with the
thread of a screw, one a right-handed screw and the other a left-handed
screw. Upon these two parts of the rod is fitted a socket or nut, cut with
interior threads, corresponding to the right and left handed threads upon the
parts of the rod. The knife can be raised or lowered, or set at any required
angle, according to the direction in which the nuts are turned. On turning
the ordinary winch handle to bring the knife down upon the paper, the con-
necting rods, in connection with the bell crank and excentric or cranks, impart
to the knife a draw and descending cut.
Figure 1 is a front elevation of one of our paper-cutting machines; and
Figure 2, a side view. A, A, is the frame; B, the platform or table; C, the
knife lever; c, c, cutting blade, secured to the knife lever by bolts and nuts;
D, D, guides for the knife to work in; E, cross bar secured to the guides
D, D; F, screw, working through the centre of the cross bar and carrying a
platten G, which is free to rise and fall in slots in the back of the guides D, D ;
H is a gauge or stop, connected to the sliding bracket J, which is fixed by
screws descending through a slot in the platform B to a similar bracket beneath
the platform. On one end of this bracket is formed a nut K. L is a screwed
shaft, which works under the table of the machine, and through the nut K the
slot formed in the table allows the block I to nove forward or backward,
according to the motion imparted to the nut by the screwed shaft. d is a
winch handle for turning the rod; M is a bell crank, connected at e by a pin
to one end of the knife lever, which it supports, and at f to an adjustable con-
necting rod N, united to a crank on end of the shaft of the main spur wheel,
as hereafter described. The fixed centre of the bell crank is at g, where it is
connected to the frame of the machine by a pin, about which it is free to
oscillate. The opposite end of the knife lever is supported upon another
adjustable connecting rod O, united to a crank formed by a pin, and one of
the arms of the main spur wheel. Both connecting rods are formed with a
bar h, h, threaded with a right-hand thread on one end and a left-hand thread
on the other, which work into two threaded sockets i, i. k, k, are parts forged

page_text: on the bars h, h, in the shape of nuts, for turning them, and thereby raising
or lowering either end or both ends of the knife as required; l' is a shaft,
supported in bearings in the frame, driven by a winch handle P¹ (not shewn
in Fig. 1); Q is a pinion on the shaft P, which gears into a toothed wheel R
on another shaft S; T is another pinion on the outer end of this shaft, which
gears into and drives the main spur wheel U, keyed on a shaft V, the opposite
end of which carries a crank W, to which the connecting rod N is affixed;
9 is a pin on one of the arms of the spur wheel U to which the connecting
rod O is affixed. A crank is thus formed on both ends of the shaft V, to
which the connecting rods N and O are affixed; X is a fly wheel on the
driving shaft P.
The operation of the machine is as follows:-The paper, card, or other board
to be cut is placed upon the table and pushed back against the stop or gauge.
The screw F is turned down, and the platten thereby depressed on to the
paper
just behind the path of the knife, whereby the paper is held tight. The winch
handle is then turned, and, through the gearing cranks and connecting rods,
the knife is brought down in a slanting direction, and caused to make a
diagonal drawing cut. Continuous rotation in the same direction causes the
knife alternately to rise and descend, performing at each descending stroke, as
before stated, a diagonal drawing cut.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, we declare that we claim as of our
Invention, first, the imparting to the knife of machines for cutting paper,
millboards, and other like substances a diagonal drawing cut or motion by
means of a bell crank, connecting rods, and cranks, working in the manner
herein-before described. And, second, the connecting of the ends of a knife,
or knife lever or carrier, in paper-cutting machines, to cranks or excentrics,
for working the same by rods, made adjustable in the manner herein-before
described, or in any equivalent manner, whereby either or both ends of the
knife may be raised or lowered.
In witness whereof, we, the said Edwin Ullmer and William Ullmer,
have hereunto set our hands and seals, this Seventh day of February,
in the year of our Lord One thousand eight hundred and fifty-six.
EDWIN ULLMEK.
