Improvements in Guillotine Paper Cutting and Trimming Machines.
We, LEONARD UPCOTT GILL of 99 Finchley Road Hampstead in the County
of Middlesex, Publisher, and ALFRED BRADLEY of, 172 Elms Road Dulwich in
the County of Surrey, Printer, do hereby declare the nature of this invention
to be as follows:-
The invention relates to a novel arrangement and combination of parts whereby
the same machine can be used according to requirements either as a divider in the
same way as an ordinary guillotine machine, or as a trimming machine whereby
edges alone are cut.
In carrying our invention, into effect we use that class of guillotine paper
trimming machine.which has a travelling gauge or stop facing the bevelled edge of
the cutting knife arranged and operated substantially as shown and described in
Specification No. 4409 of 1889 and we combine therewith on that side of the
machine having the said travelling gauge an extended sliding table to support.
the sheets of paper to be divided and in connection with such extended sliding table
we use a travelling gauge which can be set to any position according to the size of
the sheets to be divided and is caused to move by a cam away from the edge of the
paper as the latter is being divided by the knife so as to afford room for the move-
ment of the paper as it is forced forward by the bevelled face of the knife. This
gauge is caused to return to its true position automatically for gauging a fresh cut.
We also provide means for throwing either travelling gauge out of action according
to the work required to be done on the machine.
We also employ a simple arrangement of parts whereby the clutch for throwing
the machine into and out of action can be thrown out of.
gear automatically after
each cut, can be kept continuously in gear, and can be thrown out of gear by the
foot.

The sliding table is capable of being placed in contact with the fixed table to
form a convenient support for the paper to be divided and of being placed at a
distance therefrom when the machine is to be used for trimming edges and suitable
bolting means are employed for locking such sliding table in either of such
positions. The travelling gauge of the sliding table rests upon the latter and is
provided with a descending tapped lug through which passes a screwed shaft which
is capable of sliding end wise in bearings at each end. thereof fixed to suitable fixed
parts of the machine; such screwed shaft has at one end a hand wheel or crank
handle by which, it can be rotated to set the gauge, and it is connected to a lever
operated by a cam to give the required to and fro motion thereto, and the parts are
so constructed and arranged, that at one position the screwed shaft can be dis-
connected from its operating lever so as to leave the travelling gauge of the sliding
table stationary. The travelling gauge to be used when the machine is employed
for trimming edges is capable of being held out of action by a suitable bolt or stop,
and by withdrawing the latter it can be again thrown into action. The clutch rod
has a pin acted upon by a rotating arm or wiper to throw the machine automatically
out of action after each cut; this rod has a pin passing through a vertical slot in a
lever, which is capable of being operated by a treadle at any desired time to throw
the machine out of .action, and it has a longitudinal slot at its end, through
which passes a pin at the end of a lever by which the machine can be set in action

can be kept continually running until such locking pin is removed or the before
mentioned treadle is depressed. The tappet or ratchet and cam for varying the cut
are mounted on a stud in suitable position to be seen by the operative, and the cam
is provided with indicating tablets to enable the operative to see what kind of cut,
i.e., head, tail or fore-edge, can next be taken; such ratchet and cam are rotated
by a pawl operated by a cam on a revolving shaft and suitable levers and con-
nections, and a movable stop or support
operating the pawl may be allowed to follow the surface of the rotating cam or can
arranged so that when required the lever
be supported in such position as to be acted upon by such can only during a
portion of its revolution, thereby causing the pawl to drive the ratchet and
cut-varying-cam a greater or less distance, according as the different parts of the
latter are required to be brought into action.
The platen is provided with a movable portion which is normally kept in its
raised position by a spring or springs but which can be depressed and used as a
gauging bar to facilitate the adjustment of the paper when it is required to divide
:the latter.

Improvements in Guillotine Paper Cutting and Trimming Machines.
We, LEONARD UPCOTT GILL, of 99 Finchley Road Hampstead in the
County of Middlesex, Publisher, and ALFRED BRADLEY, of 172 Elms Road,
Dulwich in the County of Surrey, Printer, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly
described aud ascertained in and by the following statement :-
The invention relates to a novel arrangement and combination of parts whereby
the same machine can be used, according to requirements, either as a divider in the
same way as an ordinary guillotine machine, or as a trimming machine whereby
edges alone, are cut.
Our invention is represented in the accompanying drawings, in which
Fig. 1 is a front view, Fig. 2 a side view, Fig. 3 a back view and Fig. 4 a plan,
of our improved machine.

elevation of the pawl lever separately.
Fig. 15 is a rear view and Fig. 16 is a cross section of parts drawn to a larger
scale than the other figures.
Fig. 17 is a cross section showing the sliding table and its supporting guides.

page_text: Fig. 18 is a sectional rear elevation and Fig. 19 is a plan partly in section
showing the platen and knife with their operating slides in their lowered position
at the end of a cut.
Fig. 20 is a sectional end view of the knife bar showing one of its operating
slides.
Figs. 21 and 22 are sectional views showing one of the small adjustable stops or
gauges, and
Fig. 23 is an elevation of parts showing the stop or support 10 in different
positions.
Figs. 1, 2, 3, 4, 6 and 7 show the machine arranged to be used as a divider, and
Figs. 8, 9, 10 and 11 show it arranged to be used as a trimmer.
a a are two side frames and a is an end upright for supporting the bed or
table 6 of the machine; a is an upright for supporting the rear end of the driving
shaft C, and is a cross bar connecting the upper ends of the side frames a a.
d is the knife bar, which is mounted in slots in the upper parts of slides d' carrying
a bar d across the machine to enable the knife bar d to move endwise thereon;
these slides d¹ work in guides formed in the side frames a a and give the ascending
and descending motion to the knife bar d by means of crank pins el carried by
cranks fixed on the cross shaft e and passing through blocks d² sliding in transverse
slots d formed in the lower parts of the slides d¹.
Motion is communicated from the driving shaft c to the shaft e in the following
manner. A worin e fixed on the shaft c gives motion, through a worm wheel f', to
the shaft, and this latter, by a toothed wheel 2 thereon gearing into a toothed
wheel fixed on the shaft e, gives motion to this latter.
g is the platen, which is moved up and down in grooves a* provided in the upper
part of the side frames a by means of blocks d on the knife bar fitting into
inclined slots g in the platen, the action of which is such that as the knife bar d
descends. the blocks d will press the platen g down on to the pile of paper to be
cut; then, as the knife cuts into the pile of paper, leaving the platen behind; 'the
blocks d will, by moving in the inclined slots g', give an endway motion to the
knife bar d and produce a draw cut. In the ascending motion a spring d³ fixed at
one end to the knife bar d, and at the other to a fitting de carried by one of the
c² are
slides d, pulls the knife bar d back endwise into position for a fresh cut.
the driving pulleys and c³ is a fly wheel. is a travelling gauge or stop at the
back of the knife; it is formed to travel in inclined slots on the inner sides of
the side frames a, and it is connected by links ² to levers ³ fixed on a shaft h', on
which is fixed a weighted arm A, which, when the machine is arranged to be used
as a trimmer, tends to press the gauge to its lowest and most forward position.
The distance of the gauge h to the rear of the knife at the time when it is in its
most forward position, is regulated by the cut varying cam, which is constructed
and operated in the following manner.
mounted on a stud i
The body of such cut varring cam consists of a cylinder
fixed in one of the side frames a; it is provided around its periphery with six
adjustable studs 12, the distance of which froin the surface of the cylinder i can be
5 arranged to suit the amount to be trimmed off the different edges of the work.
These studs 2 act, in connection with an arm he fixed on the shaft h, by which the
extent of rotation of said shaft, and consequently the forward position of the
gauge h, is regulated to the extent required. The cam cylinder i is in position to
be seen by the operative and it is provided with indicating tablets ³, each havin
the word "head," "tail" or "fore-edge" applied thereto, to indicate what kind of
cut can next be taken. The cam cylinder i has fixed on its end a ratchet wheel it,
and mounted loosely on its axis is a pawl lever 1, which is connected by link to a
lever mounted on an axis 8; this lever is acted upon by a cam on the shaft e
to raise it and thereby to give a partial rotation to the cam cylinder i, and the
5 weight of said lever and parts connected therewith serves to keep it in contact
with the cam. A movable stop or support 10 is mounted on an axis on the
side frame a adjacent to the lever i, so that when required it may be turned away

of the cam, whilst, when the said stop or support 10 is turned so that the ledge 18
is under said lever, the latter is prevented from descending below a certain point
whereby it is acted upon by the cam, during only a portion of its revolution. By.
these means the pawl is caused to drive the ratchet wheel and cut varying cam i
a greater or less distance according as the different parts of the latter are required
to be brought successively, or at intervals into action.
When the machine is to be used for dividing, the lever is raised out of reach
of the cam and held in such position by resting on the ledge 13 of the stop or
support 10. An arm 7 on the shaft is acted upon by an inclined projection or
cam fixed on the knife bar d, so that when the platen g has descended on to the
work, the said projection or cam 8 shall, by depressing the arm h, gradually move
the gauge rearwards as the knife is cutting through the paper.. When the
machine is to be used as a divider the travelling gauge is raised out of action in
the position shown at Figs. 2, 3, 4, 6 and 7, and held in such position by means of
a bolt or stop acting in connection with a slot or hole in the disc ho fixed on the
shaft h, and by withdrawing such bolt or stop the gauge h can again be thrown
into action. The platen g has a movable portion 92 which is to be used as an
adjusting gauge to facilitate the placing of the paper on the machine in its correct
position for dividing; this part is normally kept in its raised position, that is, in
a line with the bottom face of the platen, by a spring g³, but it can' be depressed by
means of the knob g', as shown in dotted lines in Figs. 1 and 8, and thus enable
the pile of paper to be placed at once into the required position without having to:
move the knife bar.
h⁹
We also provide the rear part of the machine with an extended sliding table;
mounted on V guides j', to support the sheets of paper to be divided, and in
connection with such extended table' we use à travelling gauge k, which can be
set by means of the screw k' to any required position and which is caused to move'
away automatically from the edge of the paper as the latter is being divided in
order to afford room for the movement of the paper as it is forced forward by.
the bevelled face of the knife, and to return to its true position for gauging a
fresh cut. For this purpose the screw k' works in a hut k fixed to the gauge k,
and its two ends are mounted in bearings with capability of moving a certain'
distance end way therein; the screw shaft k also passes through a sliding block k
mounted in guides fixed to the underside of the bed or table b, but is prevented
moving in relation thereto by collars k. This block k is, by a fork ended link k
connected to a lever k² fixed on a shaft k³, and it has pin-jointed near the centre
thereof a slotted arm fitting and guided by the shaft e and provided with
anti-friction wheels 10 bearing against opposite edges of the cam By theseė
means the gauge is moved into and out of its gauging position and is retained for
a certain time at its foremost and rearward positions. The screw kis rotated by
a small hand wheel on the front end thereof. The gaugé k can be thrown out
of action when it is required to use the machine as a trimmer by separating the
forked end of the link from the pin at the upper end of the lever, as shown at
Figs. 8 and 10, when the said lever can move without imparting motion to the
screw and gauge k. The sliding table j is capable of being placed in contact
with the rear edge of the fixed table bas shown at Figs. 2, 4, 6, 7 to form a
convenient support for the paper to be divided, and of being placed at a distance
therefrom as shown at Figs. 8, 9, 10, 11 when the machine is to be used for trimming
edges, and a bolt j² employed as shown at Fig. 4 for locking such table in either
its forward or rearward positions.
We also employ a simple arrangement of parts whereby the clutch / for throwing
the machine into and out of action can be thrown out of gear automatically after
each cut, can be kept continuously in gear, and can be thrown out of gear when
desired by the foot. For this purpose the clutch rod has a pin 2 acted upon by
a rotating arm or wiper, 3 fixed on the shaft to throw the machine' automatically
out of gear after each cut; this rod has a pin passing through a vertical slot
24
'

page_text: n the upper end of a lever fixed on the treadle shaft k³, which is capable of being
operated by the treadle at any desired time to throw 'the 'machine out of action.
and such rod has a longitudinal slot at its front end, throngh which passes a pin
at the rear end of a lever 18, 'by depressing the outer end of which the pin i
raised above the reach of the wiper 13 and the machine set in action at any desired
time, and by the aid of this lever and a locking pin the machine can be kept
rontinuously running until such locking pin is removed or the treadle l' is depressed.
A spring around the clutch rod acts to force the latter rearward and to place
the two parts of the clutch lin gear with each other when the said rod is not pulled
forward by the wiper ³ or treadle 7.
It will be understood from the foregoing that when the machine is to be
used for trimming, the gauge h and parts acting therewith will, as shown at
Figs. 8, 9, 10, 11, 15 and 16, be in position for use, whilst the table j is in
its rearward position and the gauge k and screw ¹ disconnected from their
operating lever k by disconnecting the link from the upper end of said lever.
and that when the machine is to be used as a divider, the gauge h and parts acting
therewith will, as shown at Figs. 1 to 7, be out of action, whilst the table j is in its
forward position and the gauge k and screw connected with their operating
lever by means of the link kⓇ.
The gauge
has connected thereto a gauge bar 13 which slides in a groove in the
table band acts in connection with divisions on the sides of the groove to regulate
the position of the said gauge. By constructing the gauge k and parts connected
therewith so as to enable it to be set near to the knife it may be used both when
trimming and dividing paper.
mm are gauges working in slots in the table band adjustable by means of screws m²
working in tapped lugs m² fixed to such gauges, the said screws being capable of
rotation by means of discs m³ on the ends thereof.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a guillotine paper cutting machine, the combination and arrangement of
parts substantially as herein shown and described and for the purpose stated.:
