page_text: We, ISAAC RICHARDSON CAUTHERY and THOMAS MORTON, both of 30, Church
Bank, in the City of Bradford, Printers' Engineers, do hereby declare the nature
of this invention to be as follows:-
This invention relates to certain improvements in that class of printers guillo-
tines in which the clamp and knife are operated independently of each other,
and has for its object the construction and combination of certain mechanism
with the clamp bar, by which the said bar may be operated with greater facility
during the setting of the paper or the like preparatory to cutting, and during the
cutting operation to readily and rigidly hold the paper or the like in the required
position.
In carrying out our invention, the cutting knife is mounted and operated as
hitherto, and to the clamp bar are attached rods connected to a balanced foot
lever, by the operation of which, the clamp bar is caused to slide towards or
away from the horizontal bed plate.
To the clamp bar is attached a vertical screw, which passes through the top
cross bar of the machine provided with a nut, so arranged as to be readily engaged
and disengaged with the screw; when disengaged, the clamp bar is free to be
moved by the foot lever towards or from the paper or the like during the setting
of the same to the required gauge on the bed plate, and when the paper or the
like is in the necessary position, the clamp bar is brought upon the same and
further pressure applied to the paper or the like on bringing the nut into gear
with the before mentioned screw, on the turning of which, the paper is finally
secured for the cutting operation, which when completed, the screw is liberated
and nut withdrawn out of gear, thus freeing the clamp bar so that it may be
quickly moved clear of the paper or the like by the foot lever.
By arranging the connections with the clamp bar in the manner described, the
attendant has both hands at liberty for adjusting the paper or the like to the
required position, and by the rapid movement of the clamp bar a considerable
saving in time is effected in setting the paper or the like to the required position.
Dated this 27th day of June 1898.

page_text: of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to certain improvements in that class of printers guillo-
tines, in which the clamp and knife are operated independently of each other,
and has for its object, the construction and combination of certain mechanism
with the clamp bar, by which the said bar may be operated with greater facility
during the setting of the paper or the like preparatory to cutting; and during
the cutting operation, to readily and rigidly hold the paper or the like in the
required position.
In describing this invention in detail, reference is made to the accompanying
sheet of drawings in which Fig. 1 represents an end elevation of a machine to
which the invention is applied.
Fig. 2 is a front elevation of the same.
Fig. 3 a back elevation of the upper or head portion of the machine.
Fig. 4 a detached detail plan view of a nut and press plate for operating the
same drawn to a larger scale, and
Fig. 5 an elevation of a cam shaft for operating the press plate and nut also
drawn to a larger scale.
In carrying out this invention, the cutting knife A is mounted and operated
as hitherto by the lever B, and to the clamp bar C are attached rods D con-
nected to cross bar E, to which is connected a weighted foot lever F by rod G.
By the operation of the foot lever F on applying pressure at F', the clamp bar C
is caused to slide towards the horizontal bed plate H of the machine.
To the clamp bar C is attached a vertical screw J by a collar K secured to
the said screw within the recess L formed in the clamp bar C, the said screw
passing freely through the head frame N of the machine, so that when the
screw J is engaged with the nut M supported by the head frame N of the
machine, the clamp bar C is raised or lowered according to the direction in which
the screw J is rotated.
When the nut M is disengaged with the screw J, the clamp bar C is free to
be moved by the-foot lever F towards the paper or the like placed on the bed
plate H, on applying pressure to one end of said lever at F¹; and on removing
said pressure, the weight W causes the said clamp bar C to automatically move
clear of the paper or the like, thus by combining the foot lever F with the clamp
bar C, the setting of the paper to the required gauge on the bed plate H is accom-
plished without having to operate the screw J, by which arrangement, the
attendant has both hands at liberty for adjusting the paper or the like to the
required position, and the clamp bar to be moved rapidly towards or away from
the paper or the like by the foot lever, thus effecting a considerable saving in
time in the setting of the paper.
The nut M is supported by a slot formed in the head frame N and is made to
engage or disengage with the thread or screw J by the operation of the cam P
mounted in suitable journals supported by the head frame N.
Between the cam P and the head frame N is placed a plate Q provided with
two pins RR which pass through the head frame N to the opposite side, the
ends being in contact with the flanges of nut M, the latter being kept in contact
with the said pins by a pring surrounding a bar T compressed between a
shoulder T' on said bar and rigid bracket U.
When the cam P is clear of the plate Q in the position shown by Fig. 2, the
compressed spiral spring S forces the nut M into contact with screw so that
on rotating the screw, the clamp bar C is operated, but if the said cam be turned
so that the plate Q is forced towards the head frame N, the pins R R then force
the nut M in the direction of arrow in Fig. 4 clear of the screw, thus freeing
the said screw that the clamp bar may be operated by the foot lever F during
the setting of the paper or other material to be cut; and when the paper or the
like is set, on liberating the cam P from the plate Q, the compressed spiral

page_text: spring S on expanding, forces the nut M into contact with the threads of screw J,
so that on the turning of said screw in the right direction, the paper or the like
is finally held by the clamp bar C until the cut is completed by the operation of
lever B.
On returning the lever B to the position shown, and disengaging the nut M
from screw J in the manner as before described, the weight W on foot lever F
automatically raises the clamp bar C clear of the paper or like material, the clanıp
bar C remaining at the top until again operated by the foot lever F or screw J.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
A guillotine machine in which are combined a foot lever F with a clamp bar C
with which is connected a screw J provided with a nut M with means for engag
ing and disengaging the said nut with the screw J, all arranged and operated
substantially in the manner as shown and described, and for the purpose as
herein before set forth.
