Improvements in Guillotine Paper-cutting Machines.
We LEONARD UPCOTT GILL of 170 Strand, London, Publisher and Alfred
BRADLEY of 37 Surrey Street, Strand aforesaid, Printers Overseer, do hereby declare
the nature of this invention to be as follows:-
Our invention has reference to guillotine paper cutting machines such as are used
for cutting the edges of books, pamphlets or folded newspapers, and it relates specially
to machines in which the operator feeds the paper or material from the side of the
machine which faces the flat or cutting edge of the knife. The chief object of the
invention is to provide adjustable stops or gauges on this side of the machine without
interfering with the feed board or work table, that is to say without fitting these stops
or gauges in or upon the feed board.
With this object we provide the machine with what may appropriately be called
top stops or gauges, viz. stops or gauges carried by bars or brackets above the feed-
board and work and serving as stops to a vertical board or plate or pusher by
which the pile of paper to be cut or trimmed is moved along the feed board to the
cutter.
61
One manner in which these top stops or gauges may be arranged is as follows: To
horizontal bars fixed to the standards or framework of the machine and projecting
above the feed-board at right angles to the cutter we fit two sliding bars parallel
with the cutter and which can be adjusted by screws or otherwise at any required
positions on the fixed bars. One of these sliding bars carries stops or gauges for the
fore-edge of the pile of paper and the other carries stops or gauges for the "tail"
and "head." These stops or gauges are in the form of bars or fingers depending
from the sliding bars. On the feed-board we fit a pusher composed of two vertical
boards fitted together so as to form a piece of 1-shape; this pusher can be moved
towards and from the cutter, being preferably guided by a groove in the feed-board.
The pusher comes above the level of the lower ends of the stops or gauges.
When it is required to trim a pile of magazines or other paper the paper is placed
with its "head" in one of the angles of the pusher, which is then moved forward
until it comes against the tail stops. The cutter then descends and trims the tail.
The pile is then drawn back with the pusher and they are given a quarter turn so as
to make the fore-edge face the cutter. The pusher is then again pushed forward and
in this movement it clears the tail stops and reaches the fore-edge stops; and the
fore-edge of the pile being now under the cutter is trimmed. The pile and pusher
are again drawn back, the pusher is given a quarter turn in the reverse direction, the
pile is shifted so that its tail (already trimmed) is in the other angle of the pusher,
once more pushed forward until stopped by the tail stops and the cutter then trims
the head. The pile now completely trimmed is drawn back and removed. The angle
of the pusher into which the trimmed tail is put in order that the head may be
trimmed should have a filling in piece so that it may project further forward than the
other angle, because the length of the pile from head to tail becomes reduced after
the tail has been trimmed. The order of the cuts can be varied as desired and the
backward and forward and turning movements can be given manually or mechanically
as may be arranged. It may be found convenient to cut the head of one pile at the
samo time as the tail of the next following pile, the two piles being placed in front of
the two angles of the pusher and pushed up to the cutter together.
Another manner in which the top stops or gauges may be arranged is as follows:
From a horizontal adjustable bar above the feed board at right angles to the cutter
here depend three vertical bars the distance of which from the cutter can he
adjusted as required. The vertical bar nearest the cutter carries a fixed flat plate

page_text: set edgewise at right angles to the cutter. The middle bar has one side in line
with the said flat plate and carries a vertical plate which is parallel with the cutter;
this plate can be moved out of the way on a horizontal pin. When in position it
forms with the flat plate on the bar nearest the cutter à right angle gauge for
the fore-edge cut. The vertical bar furthest from the cutter has two vertical plates
parallel with the cutter; of those two plates the one nearest the cutter is for
lessening the distance from the cutter after the tail has been cut and it is moved
out of the way for the tail cut, but not for the head cut. During both these cuts
the vertical plate on the middle bar is moved out of the way and a right angle
gauge for the tail or head cut is formed by the flat plate on the bar nearest the
cutter in combination with the one or the other of the two plates on the bar furthest
from the cutter. The movable plates are preferably connected by links and a rod
or otherwise, so that as the plate on the middle bar is moved into position the
plate or plates on the bar furthest from the cutter move out of position and vice
versa. In this arrangement the pusher is not required.
"
Our invention comprises an arrangement of front stops similar to that last described
but fitted on the feed board instead of to a bracket or frame above. The stops or
gauges are carried by a stand or base fixed to the feed board and adjustable to right
or left; and the stops or gauges themselves except the one nearest the cutter are
adjustable to and from the cutter. The vertical plates which are parallel to the
knife and constitute one side of the right angle gauges for the fore-edge, tail and
head cuts respectively, move on horizontal pins as in the arrangement previously
described and, as in that arrangement, are preferably connected so as to work in
unison, the one moving out of position while the other or others move into position
and vice versa.

Improvements in Guillotine Paper-cutting Machines.
We, LEONARD UPCOTT GILL of 170 Strand, London, Publisher and ALFRED
BRADLEY of 37 Surrey Street Strand aforesaid Printers' Overseer do hereby declare
the nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Our invention has reference to guillotine paper cutting machines such as are used
for cutting the edges of books, pamphlets, or folded newspapers and it relates
specially to machines in which the operator feeds the paper or material from the side
of the machine which faces the flat or cutting edge of the knife.
The invention consists of the hereinafter described arrangement of stops or gauges
fitted on the feed board. The stops or gauges are carried by a stand or base fixed
to the feed board and adjustable thereon to right or left and the stops or gaugos
themselves, except the one nearest the cutter which may be either fixed or adjustable,
are adjustable to and from the cutter. The stop nearest the cutter is a flat plate or
board set edgewise at right angles to the cutter so as to form a facing plate or
side stop for squaring the work to be cut. The next stop or gauge is a vertical
plate parallel with the cutter. It can be moved out of the way on a horizontal
pin or axis and when in position it constitutes with the side stop nearest the cutter,
a right angle gauge for the fore edge cut of the pile of paper. The stop or
gauge furthest from the cutter consists of two vertical plates parallel with the
cutter of these two plates the one nearest the cutter is for lessening the distance
from the cutter after the tail of the pile of paper has been cut, and comes into
position for the head cut it is out of the way during the tail cut. During both these
cuts that is to say the tail and head cuts the vertical plate forming the gauge for the
fore edge cut is moved out of the way and a right angle gauge for the tail or

page_text: Dead cut (as the case may be) is constituted by the side stop in combination with
the one or the other of the two plates which gauge the tail and bead cuts respectively.
These plates and the plate which gauges the fore edge cut are preferably connected
by links and a rod or otherwise so that as the plate for gauging the fore-edge cut is
moved into position the plates for gauging the tail and head cuts move out of position
and vice-versa.
The accompanying drawings represent so much of a guillotine paper cutting
machine as is necessary to illustrate our invention.
Figure 1 is a side elevation of our arrangement of stops or gauges in the position
they occupy at the time of making the fore-edge cut. The feed board, the cutter and
other parts of the machine which do not constitute part of the present invention are
shown in section.
Figure 2 is a plan,

Figure 1 (the gauge for the fore-edge is however not shown in Figure 4).
Figure 5 is a view the same as Figure 1 but showing the stops or gauges in
the position they occupy at the time of making the head cut.

or plate which gauges the fore-edge cut. It is mounted on a horizontal pin or
axis carried by a bracket m the distance of which together with that of the plate k
from the cutter can be regulated by means of the dove-tail plate n on the bracket,
the dovetail p in the stand or base and the set screw r. s and are respectively
the plates for gauging the tail and head cuts. They are mounted on a horizontal
pin or axis u carried by a bracket which is adjustable like the bracket m by means
of the dove-tail plate w, dovetail p, and set screw it. The plates and s are each
connected by a link y, y to a corresponding arm on a rod 1, free to turn on its axis
in bearings or supports. The two arms, are on diametrically opposite sides
of the rod so that when the plate is moved up, the plate s is moved down and
vice-versú.
-The gauges being
The action of the apparatus may be shortly described as follows
in the position shown in Figures 1 to 4 for the fore-edge cut, the pile of paper is
placed with its back against the plate or gauge k and its head against the stop i, these
two parts and together constituting a right angle gauge. When the fore-edge
has been cut the plate s is moved by means of the button or knob s¹ from the vertical
position seen in Figures 1, 2 and 4 into the position seen in Figure and in dots in
Figures 2 and 4, and during this movement the plate & through the action of the
links arms and rod moves into the vertical position. The pile of paper is now
placed in position for the tail cut, the fore-edge being placed against the stop i and
the head against the plate or gauge s. When the tail cut has been effected the plate t
which has hitherto remained in the vertical position shown in Figures 1, 2 and 4 is
moved by the button or knob t' into the horizontal position seen in Figure 5. The
pile of paper is now placed in position for the head cut the back being placed against
the stop and the tail against the plate or gauge t. When the head has been cut the
plates is lifted by its button s' and carries the plate with it by means of the
button, and the plate simultaneously moves back into the position seen in
Figures 1 to 4 ready for the fore edge cut of the next pile of paper. The plate
when moved to or a little beyond the vertical position by the plates drops to the
position seen in Figure 4 owing to its centre of gravity being above the pin or axis u

page_text: and is prevented going beyond this position by a suitable stop or by its edge coming
against the base fas seen in Figure 1. In this position it is not liable to move when
the plate s is next returned to the horizontal position.
The drawings show our apparatus placed at the right hand side of the feed board;
it is obvious however that it can be placed at the left hand side by properly roversing
the arrangement of the parts.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim in respect of guillotine paper cutting machines is :-
1. The combination of the stop i, the gauge, stop or plate for the fore edge cut and
the gauges stops or plates s and i, for the tail and head cuts substantially as hereiubefore
described and shown in the accompanying drawings.
2. The combination with the gauges, stops, or plates k and s of means whereby
when the plates is moved out of position, the plate & moves into position and vice-versá
substantially as hereinbefore described and shown in the accompanying drawings.
3. The combination or arrangement of parts substantially as herein before described
and represented in the accompanying drawings forming an improved apparatus for
gauging piles of paper to be cut or trimmed in a guillotine cutting machine.
