I WILLIAM POWRIE of 45 Northway, Road, Loughboro, Junction London in the
County of Surrey Engineer, do, hereby declare the nature of this invention to be as
follows:
The application of an apparatus, attached to, or in connection with the back fence
or gauge of Guillotine Paper cutting machines, by means of which the material,
books, paper, &c. after. being cut is pushed forward so as to enable the Cutter to seize
it without having to put his hands under the knife of the machine. This I propose
to effect by connecting the front plate of the back guage by levers, tappits, rods to
a foot lever or treddle in front of the machine and under the control of the attendant.
These are so arranged that by. a pressure of the Cutter's foot the said front plato is
pushed forward several inches and with it the, material to be taken out of the machine
the front plate returning automatically to its original position.

page_text: Improvements in Guillotine Paper Cutting Machines.
I WILLIAM POWRIE of Number 45 Northway Road Loughboro' Junction
London S.E. Engineer and Machinist 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 and accompanying Drawings:
:-
My invention relates and is applicable to Guillotine paper cutting machines which
are used for trimming and cutting books, paper, and other materials and more
especially to machines which are driven by power and are fitted with an automatic
motion for stopping the knife after each cut. while the flywheel remains in continuous
motion.
.
In such machines it is necessary for the operator, or cutter," to put his hands
under the knife to remove the books or other material which has been cut and several
cases have occured in which through want of caution on the part of the "cutter," or
a failure of some of the automatic gear the knife has come down unexpected and caused
serious injury to the "cutter's" hands.
The object of my invention is to remove this risk of injury by providing an appliance
for delivering the material into the cutters hands without his having to put them
under the knife at all. This I do by arranging the back fence or gauge so that the
front portion of it is propelled forward by a treadle motion worked by the "cutter's"
foot or otherwise which pushes the material forward a few inches so as to be readily
seized and moved by the " cutter as required.
""
My invention will be best described with reference to the accompanying drawings
in which Fig. 1. represents a side elevation of so much of a Guillotine paper cutting
machine as is necessary to the illustration of my invention and Fig. 2. is a back view
of the same machine.
In the said Figs. A. A. represents the side frames B. the centre stay C. the table
D. E. F. the back fence and K. the. knife of a Guillotine paper cutting machine.
6. 6. are fixings secured to the back part of the fence or cast on it in which rotates
the shaft 2. carrying the crank lever 1. and the cam levers or "tappits" 3.3. F. is
a flat plate to which is secured the rods 4. and 5. the rods 4. 4. being fitted with
spiral springs in compression which keep the_plate F. close up to the back fence.
The rods 5. 5. work through the fixings 7. 7. and are fitted with antifriction rollers to
reduce the friction of contact with the tappits 3. 3. a. a. are fixings secured or cast
on the edge of the back table and serve as supports for the parralel motion c. c. b.
which is worked by the connecting rod d. and the treadle lever e. f being a stud or
pin secured to the frame to serve as a fulcrum for the lever e.
The manner of using the apparatus is as follows-The "cutter" places his foot
on the treadle lever e. and elevates the parralel bar b. which by its action on lever 1.
causes the shaft 2. to partially rotate and with it the "tappits” 3. 3.
These by
their action force forward the rods 5. 5. and with them the plate F. and the books
or other material M. into the position shown by the dotted lines which enables the

page_text: "cuttor" to remove the material without putting his hands under the knife. When
the pressure of the foot is removed the springs on 4. 4. withdraw the plate F. into its
original position in time for the next quantity of material.
These details may be varied and other equivilent mechanical movements may be
applied to effect the same or a similar result or the apparatus may be worked by
the "cutter's" hand or made self acting and worked automatically from the other
parts of the machine.
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) The parts of a Guillotine paper cutting, machine constructed and acting sub-
stantially as and for the purposos set forth.
(2) In a Guillotine paper cutting machine arranging and fitting the back fence or
guage so that the front part or a portion or portions of it may be advanced a few
inches to propel the material forward after each cut or when desired.
(3) The arrangement of parts substantially as described and for the purpose
indicated and set forth.
