PROVISIONAL SPECIFICATION.
An Improvement in Guillotine Cutting Machines, whereby Paper of
a Narrow Gauge can be Readily Cut.
I, JOHN DALY, of 3 Swift's Row, Lower Ormond Quay, Dublin, Ireland,
Printer, do hereby declare the nature of this invention to be as follows:
In guillotine cutting machines as at present employed, considerable difficulty is
experienced in cutting narrow strips of paper owing to the thickness of the
clamping block coming in contact with the sliding back of the cutting table.
The object of this invention is to overcome this difficulty, and to this end
I propose to form a longitudinal plate of suitable dimensions, on the front edge of
which are hinged two lugs so arranged that when there is no weight upon them
they will be held in an elevated position by means of feather springs arranged
underneath. This plate is placed on the cutting table against the sliding back-
the edge provided with the lugs, being outward-and is operated by the same
spiral screw which operates the present sliding back.
Its action is thus:-
When in position the lugs will stand upright and form a stop or back against
which presses the edge of the paper to be cut, and as the clamping block descends
the lugs will yield or be depressed until the block closes firmly on the paper
whereupon the guillotine acts in the usual manner.
It will thus be perceived that although the lugs act as a stop or back for the
paper, they offer no resistance to the descent of the clamping block.

An Improvement in Guillotine Cutting Machines, whereby Paper of
a Narrow Gauge can be Readily Cut.
I, JOHN DALY of 3 Swift's Row Lower Ormond Quay, Dublin Ireland,
Printer, 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 :-
In guillotine cutting machines as at present employed, considerable difficulty is
experienced in cutting narrow strips of paper owing to the thickness of the
clamping block coming in contact with the sliding back of the cutting table.
The object of this invention is to overcome this difficulty and to this end
I propose to form a rectangular plate of suitable dimensions, on the front edge of
which are hinged two lugs so arranged that when there is no weight upon them
they will be held in an elevated position by means of feather springs arranged
underneath. This plate is placed on the cutting table against the ordinary sliding
back of same-the edge provided with the lugs being outward.

page_text: The accompanying drawings will enable my said invention to be more readily
understood and carried into practice.
Fig. 1 illustrates an ordinary paper cutting machine of the guillotine type
showing the application of my invention thereto, and
Fig. 2. shews my improved contrivance detached.
A, is the rectangular plate which may be of any suitable dimensions according
to the class of work to be done; b. b. are the lugs hinged in recesses formed in its
front edge and maintained in an elevated position by the feather springs c. c.
A raised ledge d is provided on the back edge to impart strength and increase
the contact surface between the plate and the ordinary sliding back, e, of the
machine.
The action of my invention is as follows:-
When the contrivance is in position, the lugs stand upright and constitute a stop
or back against which presses the edge of the paper to be cut (it being understood
that the paper instead of being placed at the back of the knife is arranged in
front) and as the clamping block descends the lugs will yield or recede until the
clamping block closes firmly on the paper whereupon the knife acts in the usual
manner.
It will thus be perceived that although the lugs act as a stop or back for the
paper, they offer no resistance to the descent of the clamping block which can
readily be brought down as far as the thickness of the plate will permit.
By the use of my invention it is obvious that strips or bands of paper of the
narrowest practical width can readily and conveniently be cut irrespective of the
thickness of the clamping block which hitherto limited the width in operating
paper cutting machines of the ordinary guillotine type.
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
First. In paper cutting machines of the guillotine class the use and application
of a contrivance whereby strips or bands of a narrow width can readily be cut, in
the manner substantially as herein specified.
Second. In the operation of cutting narrow strips or bands of paper the use of a
contrivance as herein described in combination with paper cutting machines of
the guillotine class in the manner substantially as herein specified and set forth.
