PROVISIONAL SPECIFICATION.
An Improved Punching or Cutting Machine for Paper or Cardboard
used for Box Making or other Purposes.
WILLIAM CROSLAND New Street Miles Platting Manchester Machinist do
hereby declare the nature of this invention to be as follows:-
On a suitable stand I fix a vertical iron plate, planed perfectly true on one side
& perforated with horizontal slots suitable for bolts, for convenience of explanation
I will call this plate the foundation, above this plate is another of similar shape &
size & in exactly the same plane as the foundation but fixed in slides & geared
in such a manner as to move up & down continuously a small distance but always
maintaining the same plane as the foundation, this upper plate which I will call the
slide is also perforated with slots for bolts, by this arrangement punches, dies, or
shears in great variety can be fixed & worked in such a manner as to allow all the
cuttings to drop on the floor & not impede the working of the machine as one
cutter is fixed on the foundation & the reverse is fixed on the slide & approach
cach other at every revolution of the machine each time cutting out the shapes
required as the cardboard is fed in between the upper & lower cutters.

COMPLETE SPECIFICATION.
An Improved Punching or Cutting Machine for Paper or Cardboard
used for Box Making or other Purposes.
I, WILLIAM CROSLAND of New Street, Miles Platting Manchester, in the
County of Lancashire, 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:-
My invention consists of two vertical surfaces one of which is fixed and
stationary, whilst the other rises and falls alternately, and thus approaches and
retires from the stationary surface, which is placed below it.
This will be best understood by the drawings which I have provided, marked
with letters of reference.
Fig. 1. is the front elevation of the machine.
Fig. 2. is the side elevation of the same.
Fig. 3. is plan, of upper part of machine.
A. see Figs. 1. & 2. is a cast iron frame fixed in a vertical position on two
feet B. B.
On the outer edge of this frame are two dove-tailed strips D. D. see Figs. 1. & 3.
between which is placed a smaller frame C. which is also dove-tailed at the edges to
fit the strips D. D. between which it moves up and down a short distance.
The centre part of frame A. is a planed surface E. and stands forward to the
front of frame C. It is perforated with slots or bolt-holes for convenience in
fastening the cutters or dies. Immediately above this surface is a similar surface F.
being part of frame C. also perforated with slots or bolt-holes, for fixing the upper
set of cutters or punches K. which are made to fit the cutters and dies K 1 fixed on
surface E. In the lower part of frame A. is a round hole or bearing, carrying the
shaft G. with eccentric H. and eccentric-rod I, which is connected to frame C.
On the opposite end of shaft G. is a pulley, or pair of pulleys J. turned by a
stron

page_text: The mode of operation is as follows :-
When the pulley J. is set in motion eccentric H. lifts up and down the frame C.
causing the cutters K fixed on surface F to rise and fall with it. The material to
be cut is placed between the higher and lower cutters K and K 1 and is acted upon
at each revolution of the machine, and the waste cut from the material is allowed
to fall on the ground.
Having thus described the nature of my invention, I wish it to be understood
that I do not confine myself to any of the details herein described, nor any
particular form of cutters or punches but, what I claim is :-
Two vertical surfaces, one of which moves up and down above the other,
perforated with slots or bolt-holes, for convenience of fixing punches or cutters, of
any required form, or at any required distance from each other.
Dated this 25th day of March 1892.
WILLIAM CROSLAND.
