Improvements in Guillotine or Paper Cutting Machines.
I, ROBERT CUMMING ANNAND of Cornwallis Street, South Shields in the
County of Durham, Printer and Publisher, do hereby declare the nature of this
invention to be as follows:-
:―
My invention has reference to guillotine paper cutting machines in which the
pile of paper to be cut is fed from that side of the machine which faces the flat or
cutting side of the knife and it relates specially to constructing these machines so
that they will automatically trim or cut the edges of books, folded newspapers and
the like.
According to my invention I make the feed table so that it can be moved
forwards and backwards and in the middle of same fit a revolving circular disc
let into the table so as to be flush with the top thereof. Across the centre of the
disc is a ridge or flat piece placed edgewise, and at right angles to this ridge is an
adjustable gauge.
Above the disc is a clamping disc carried by a vertical rod which can be moved
up and down and can also be caused to turn with its disc by means of bevel or
other gearing. When the machine is at work the upper disc or clamp is held down
upon the pile of paper or material to be cut by a spring but when the machine is
stopped the mechanism which disconnects the driving power also raises the
clamping disc.
The operation of the machine is as follows:-The usual clamp and the cutter
being in their raised position the attendant places a pile of material say for example
a pile of pamphlets upon the table with the "tail" against the gauge the "head"
towards or under the cutter and the back against the ridge on the disc. He places
a similar pile also with the back against the ridge but with the head against the
gauge and the tail towards or under the cutter. He then by moving a handle or
otherwise releases a catch which holds up the clamping disc and this disc is
therefore forced down by its spring upon the two piles of pamphlets. The machine
is then started, the usual clamp and the cutter descend and the cutter trims those
edges of the two piles which are beneath it, viz. the head of the first pile and the
tail of the second. The cutter and clamp next rise through the automatic action
of the machine and when they are clear of the piles these are given a quarter
revolution together with the discs between which they are held. The clamp and
cutter then again descend and cut the fore-edge of one of the piles. The cutter
and clamp having again risen the piles and discs receive another quarter turn
so that in the third descent of the cutter the tail of the first pile and the head
of the second are cut. The clamp and cutter having again risen and the piles
and dises having received another quarter turn the cutter in its fourth descent
cuts the fore-edge of the other pile. When the clamp and cutter rise the fourth
time the piles and discs receive another quarter turn which brings them back to the
starting position, the driving gear is automatically stopped and the clamping disc
lifted clear of the piles. The piles which have each been trimmed on three sides
can then be removed by the attendant and two untrimmed piles put in their places;
he then again starts the machine and the same cycle of operations is performed.
At every rise of the cutter the feed table is caused to move backwards or
forwards to the extent required by the work in hand which extent will be regulated
according to the relation between the length and the width of the piles. The

page_text: movement of the table is effected by the mechanism which imparts rotation to
the discs.

COMPLETE SPECIFICATION.
Improvements in Guillotine or Paper Cutting Machines.
I, ROBERT CUMMING ANNAND of Cornwallis Street, South Shields in the
County of Durham, Printer and Publisher, 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:-
My invention has reference to guillotine paper cutting machines in which the
pile of paper to be cut is fed from that side of the machine which faces the flat or
cutting side of the knife, and it relates specially to constructing these machines so
that they will automatically trim or cut the edges of books, folded newspapers and
the like.
According to my present invention I make the feed table so that it can be moved
forwards and backwards, and in the middle of same I fit a circular disc which is let
into the table so as to be flush with the top thereof. This disc has an intermittent
rotary motion, each of its movements being equal to one-fourth of a revolution.
Across the centre of the disc is a ridge or flat piece placed edgewise, and at right
angles to this ridge is an adjustable gauge. Above the disc is a clamping disc
carried by a vertical rod which can be moved up and down and can also be caused
to turn with the discs by means of bevel or other gearing. When the machine is
at work the upper dise or clamp is held down upon the pile of paper or material to
be cut by a spring, but when the machine is stopped the clamping dise is raised.
The accompanying drawings represent SO much of a guillotine machine
constructed according to my invention as will enable my improvements to be fully
understood.
Figure 1 is an elevation of the feed side of the machine; Figure 2 is an elevation
taken at right angles to Figure 1, the feed table and some of the other parts being
shown in section.

a is a toothed wheel keyed on the shaft from which the knife or cutter c and
usual clamp (not shown) are worked in the ordinary manner. d is another toothed
wheel gearing with the wheel a and having the same number of teeth so as to make
the same number of revolutions; this wheel d is loose on its shaft e and is formed in
a piece with or fixed to a cam which is concentric therewith. In the cam f runs
a roller g on one arm of a lever which has its fulcrum at . The other arm of
the lever is connected by a link to a frame l. The length of the link k can be
increased or diminished at will by screwing the screw m to a less or greater extent
into the nut n by means of the hand wheel p. The point of connection of the link k
to the lever h can also be raised or lowered as desired so as to increase or diminish
the active length of the lever. The frame carries the feed table y which is
mounted in guides in the framework. It will readily be understood that as the
knifee and usual clamp make one up and down stroke for every revolution of the
shaft, the frame and feed table will make one forward and backward movement
for every revolution of the same shaft, and that the extent of the movement of the
frame and feed table will depend upon the length of the link k and its point of
connection to the lever h. The movement of the feed table g must be so timed that
it is at the forward or inner end of its stroke when the, usual clamp, and knife
complete their descent. In the, middle of the feed table is fitted, a discs flush with
the top thereof. Across the centre, of this disc is a ridge or flat piece t placed

v
edgewise, and at right angles to this ridge is a gange u which is movable inwards and
outwards in guides or slots in the table, the extent of its movement inwards being
adjustable in any convenient manner. Above the disc s is a clamping disc s' carried
by a vertical rod and the two discs and rod have an intermittent rotary motion,
cach of their movements being equal to a quarter revolution and taking place after
every backward movement of the table, so that the discs make one complete
revolution for every four forward and backward movements of the table and for
every four up and down movements of the knife. The intermittent rotation of the
discs and their rod is effected as follows:-The lower end of the rod v is
connected by bevel gearing to with a shaft a free to slide to and fro on a key
or feather y in the shaft e (which is hollow) in accordance with the forward and
backward movements of the frame 1. The wheel is loosely mounted on the
shaft e while a four toothed wheel or disc is keyed on the said shaft. Embracing
the same shaft but fixed to the framework is a cain A upon which a roller B bears;
this roller is carried by a lever C pivotted to the wheel dat D, and a spring E
connected to the tail of the lever keeps the roller pressed against the cam A. The
roller B is sufficiently long to extend across both the cam A and the wheel. The
cam is so shaped that it keeps the roller out of the teeth of the wheel during
three-fourths of the revolution of the wheel d and allows it to engage therewith
during the other fourth of the revolution. Consequently the wheel and its shaft e
only revolve during one-fourth of the revolution of the wheels a and d, and it is
during this fourth revolution that they impart a quarter turn through the bevel
gearing w w to the rod and discs & s¹. F is a spring which normally keeps the
clamping disc a' down upon the pile of paper or material placed on the table.

The operation of the machine is as follows:-The usual clamp and the cutter c
being in their raised position as seen in the figures the attendant places a pile of
material, say for example a pile of pamphlets upon the table y with the "tail"
against the gauge u, the "head" towards or under the cutter, and the "back"
against the ridge on the disc s. He places a similar pile also with the
back against the ridge but with the head against the gauge and the tail towards or
under the cutter. He then moves back the gauge. He next by moving a handle H
(or otherwise) releases a catch I which holds up the clamping disc s' by pressing
against a roller K on the rod and this disc is therefore forced down by its spring F
upon the two piles of pamphlets. The machine is then started, the usual clamp
and the cutter c descend and the cutter trims those edges of the two piles which are
beneath it viz. the head of the first pile and the tail of the second. The cutter
and clamp next rise through the ordinary automatic action of the machine and
when they are clear of the piles these receive a quarter revolution in the manner
already explained together with the discs s s' between which they are held. The
clamp and cutter e then again descend and cut the fore-edge of one of the piles.
The cutter and clamp having again risen the piles and discs receive another quarter
turn so that in the third descent of the cutter the tail of the first pile and the head of
the second are cut. The clamp and cutter having again risen and the piles and
discs having received another quarter turn the cutter in its fourth descent cuts the
fore-edge of the other pile. When the clamp and cutter rise the fourth time the
piles and discs receive another quarter turn which brings them back to the starting
position, the driving gear is automatically stopped and the clamping disc lifted
clear of the piles owing to the roller K rising up the catch 1. The piles which
have each been trimmed on three sides can then be removed by the attendant and
two untrimmed piles put in their places; he then again starts the machine and the
same cycle of operations is performed. For every rise and descent of the cutter
the feed table moves backwards and forwards to the extent required by the work
in hand, which extent will be regulated according to the relation between the
length and the width of the piles. The gauge u is adjusted according to the length
of the piles while the link k and its connection with the lever are adjusted
according to the width of the pile in relation to the length.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
1. In a guillotine or paper cutting machine, a feed table having a forward and
backward movement, in combination with a horizontal dise fitted in the table and
having an intermittent rotary motion equal at each movement to a quarter
revolution for one forward and backward movement of the table, and for one up
and down movement of the knife, substantially as and for the purpose hereinbefore
described.
2. The combination with a feed table and dise arranged and working as described
in Claim 1, of means substantially as herein before described for regulating the
extent of the forward and backward movement of the table for the purpose set
forth.
