Improvements in Guillotine Machines for Cutting Paper or other
material.
We LEONARD UPCOTT GILL of 170 Strand, London, Publisher and ALFRED
BRADLEY of Stanhope House, Drury Lane London Printer's Overseer, do hereby
declare the nature of this invention to be as follows :-
This invention has reference to guillotine cutting machines such as are used for
cutting the edges of books, pamphlets or folded newspapers, and of the kind in
which the operator feeds the pile of paper from that side of the machine which
faces the flat or cutting edge of the knife. The invention consists of a particular
combination of gauges or stops specially intended for use in cutting paper that has
been folded to "register," and having unequal edges, but it can also be employed
for trimming paper that has been folded to edge and for cutting and trimming to
shape card or other material for boxes, labels and the like.
One advantage obtained by the said combination of gauges or stops is that when
it is only required to cut the fore-edge and head of a pile of folded papers, that is
to say to leave the tail uncut this can be done, whereas in other machines the tail
cut must be first taken in order to gauge the head cut; and further the said
combination admits of cutting or trimming printed or other work either folded or
open so that the cut or trim shall be exactly true to or parallel with the print or
other register mark and this cutting or trimming to register may be performed
either with or without the tail cut being made.
For the purpose of the invention as applied to newspaper and book trimming we
employ two adjustable gauges or stops upon the feed board for the fore edge and
the tail respectively and a third gauge or stop behind the knife for the head, this
third gauge being a movable or travelling gauge actuated by suitable mechanism
such for example as that described in the Specification of Leonard Upcott Gill
No. 4409 of 1889; this gauge can be set to automatically gauge every third cut or
every second cut as may be desired.
The distance from the knife of the two gauges on the feed board can be adjusted
as required by means of screws and nuts and longitudinal slots in the feed board,
or in any other suitable manner.
For the purpose of cutting and trimming other descriptions of work three or more
of the feed board gauges or stops are used as required.
The operation as regards book or newspaper work requiring three cuts is as
follows: The gauges or stops having been properly adjusted the machine is started.
The pile of paper is then put with its back against the fore edge gauge on the feed
board and the fore-edge will consequently project beyond the line of the knife
which will cut or trim it at its next descent. The pile is next put with its head
against the tail gauge on the feed board and the tail will then project beyond the
line of the knife and be cut or trimmed at the next descent. The head is then
pushed under the knife against the movable or travelling back gauge and is cut or
trimmed at the next descent.
When it is not required to cut the tail the tail gauge is not utilized and if desired
can be temporarily removed from the machine.
Of course the order in which the cuts are effected can be varied as wished.

Improvements in Guillotine Machines for Cutting Paper or other
material.
We, LEONARD UPCOTT GILL, of 170 Strand London, Publisher, and ALFRED
BRADLEY of Stanhope House, Drury Lane, London, Printer's 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 :-
This invention has reference to guillotine cutting machines such as are used for
cutting the edges of books, pamphlets or folded newspapers, and of the kind in
which the operator feeds the pile of paper from that side of the machine which faces
the flat or cutting edge of the knife. The invention consists of a particular
combination of gauges or stops specially intended for use in cutting paper that has
been folded to "register," and having unequal edges, but it can also be employed
for trimming paper that has been folded to edge and for cutting and trimming to
shape card or other material for boxes, labels and the like.
One advantage obtained by the said combination of gauges or stops is that when
it is only required to cut the fore edge and head of a pile of folded papers, that is
to say, to leave the tail uncut, this can be done, whereas in other machines the tail
cut must be first taken in order to gauge the head cut; and further the said
combination admits of cutting or trimming printed or other work either folded or
open so that the cut or trim shall be exactly true to or parallel with the print or
other register mark and this cutting or trimming to register may be performed
either with or without the tail cut being made.
For the purpose of the invention as applied to newspaper and book trimming we
employ two adjustable gauges or stops upon the feed board for the fore edge and
the tail respectively and a third gauge or stop behind the knife for the head, this
third gauge being a movable or travelling gauge actuated by suitable mechanism
such for example as that described in the Specification of Leonard Upcott Gill
No. 4409 of 1889; this gauge can be set to automatically gauge every third cut or
every second cut as may be desired.
The distance from the knife of the two gauges on the feed board can be adjusted
as required by means of screws and nuts and longitudinal slots in the feed board,
or in any other suitable manner.
For the purpose of cutting and trimming other descriptions of work two or more
of the feed board gauges or stops are used as required.
The operation as regards book or newspaper work folded to "register" requiring
three cuts is as follows:-The gauges or stops having been properly adjusted the
machine is started. The pile of paper is then put with its back against the fore
edge gauge on the feed board and the fore edge will consequently project beyond
the line of the knife which will cut or trim it at its next descent. The pile is next
put with its head against the tail gauge on the feed board and the tail will then
project beyond the line of the knife and be cut or trimmed at the next descent.
The head is then pushed under the knife against the movable or travelling back
gauge and is cut or trimmed at the next descent.
The accompanying drawings represent so much of a guillotine machine constructed
according to this invention as will enable the present improvements to be fully
understood. Figure 1 is a plan of the feed board, the dotted rectangles A B and C
indicating the position of the pile of paper or material at the times when the fore
edge, the tail and the head are respectively cut. Figures 2, 3 and 4 are vertical
sections on the lines 2-2, 3-3 and 4-4 respectively of Figure 1 and also show
the knife, knife bar, clamp, movable or travelling back gauge and adjacent parts.
a is the knife, 6 the knife bar, c the clamp, and d the movable or travelling back 5
gauge, this gauge is actuated by the mechanism described in Specification No. 4409

page_text: of 1889 already hereinbefore referred to, and when it is required to cut or trim
three edges of the pile the said gauge will be set, as will be understood on reference
to the said Specification to automatically gauge every third cut. e is the feed
board and ƒ and g are two adjustable gauges thereon, the gauge f being for the fore
edge and the gauge 7 for the tail of the pile. The adjustment of these gauges is
effected by means of screws h h fitted with hand wheels ii and working in nuts kk,
these nuts being formed in the gauge carriers which can move in slots m m in
the feed board. "It is obvious however that other means of adjusting the gauges f
and g could be adopted.
In working the machine, the gauges having been first properly adjusted, the back
of the pile is put with its back against the fore edge gauge g (see A Figures 1 and 2).
The fore edge of the pile which will thus project beyond the line of the knife will
consequently be cut when the knife descends. Next the pile is put with its head
against the gauge 9 (see B Figures 1 and 3); the tail will thus project beyond the
line of the knife and be cut at the next descent. The head of the pile is then
pushed under the knife against the movable or travelling back gauge d which for
this third descent of the knife moves forward the necessary distance to act as a
gauge (see C Figures 1 and 4) and consequently the head is cut. Of course the
order in which the cuts are effected can be varied as wished.
When it is not required to cut the tail the tail gauge g is not utilized and if
desired can be temporarily removed from the machine. The travelling back gauge d
should then be set to automatically gauge every second cut.
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 is :-
In guillotine machines of the kind herein referred to the combination of adjustable
gauges or stops on the feed board and of a movable or travelling gauge behind the
knife substantially as and for the purpose hereinbefore described.
