Machine for Cutting Paper into Strips or Shavings.
We, RICHARD JAMES ROUSAY, Assistant Manager, and WILLIAM GARDNER
SINCLAIR, Manufacturing Stationer, both of St. Clair Works, Albert Street,
Edinburgh, N.B., do hereby declare the nature of this invention to be as follows:-
This invention relates to a machine for cutting paper into strips or shavings.
It is constructed on the rotary principle, having two sets of circular cutters
which will be 4" diameter more or less, and of different thicknesses according
to the width of shavings to be cut. These cutters are arranged on two spindles
intersected with washers of a similar diameter, but of the same thickness, i.e. to
cut 1/32" in breadth. The knives require to be 1/32" in thickness, as also the
washers.
The edges of the knives are turned dead square and the sides polished.
The washers may be of cardboard, rubber, metal or other substance.
There is an upper and a lower cutter, the latter working into the former or
vice versa, i.e. for cutting in breadth there are 120 knives on the top and 120
knives on the bottom spindle to cut a sheet 30" in width. For the purpose of
preventing the paper from being carried round the spindles between the knives
there is a piece of brass or other metal attached, close to and between the knives
so as to lead the shaving away and thus keep both top and bottom cutters always
clear.
The paper may either be fed into the machine in sheets or from the reel. The
latter is the method we purpose adopting in the meantime. The reel or reels
will be attached behind in the machine. The machine will be constructed to
cut a single or any number of sheets up to twenty or more at one time.
The paper is conveyed to the cutters by means of two or more rollers, and after
passing through the cutters the strips or shavings are again conveyed by means
of one or more rollers on to the back table of the machine on a certain part of
which there is erected a dead knife with gearing for another circular cutter, for
the purpose of cutting the strips or shavings from the web into any length
required.
This having been done, the shavings or strips drop on to the endless canvas sheet
and are thus conveyed to a receptacle ready to be packed up. The gearing and
power of the machine is arrived at by means of pinions, wheels, pulleys, springs
and cams.
The machine may be adjustable so as to cut any width of strip or
shaving.
Dated this 12th day of April 1897.

We, RICHARD JAMES ROUSAY, Assistant Manager, and WILLIAM GARINER
SINCLAIR, Manufacturing Stationer, both of St. Clair Works, Albert Street,
Edinburgh, 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 relates to a machine for cutting paper into strips or shavings.
constructed on the rotary principle, having two sets of circular cutters of different
thicknesses according to the width of shavings to be cut.
But in order that our said invention may be more readily understood and easily
carried into effect we will proceed to describe the same with reference to the
accompanying drawings in which
Fig. I is an elevation.
Fig. II a plan and
Fig. III an end view of a machine constructed in accordance with our said
invention.
Fig. IV. is an elevation and
4)3
Fig. Va plan, to a larger scale, of the rotary cutter shewn in Figs. I and II.
Referring to the said drawings we employ a frame of iron or other suitable
metal consisting of standards A bound together by stays a. Secured firmly upon
the top of this frame, by bolts or otherwise, are two cast iron portions B for
supporting the revolving cutters C, C and rollers.
I
The before mentioned revolving cutters C, C' consist of circular discs or
knives C (Figs. IV and V) of about 4" diameter more or less, having the edges
turned dead square and the sides polished. The said knives are arranged
on two shafts or spindles c, c¹ intersected with washers C³ of a smaller diameter
but of the same thickness as the knives. The shaft c carrying the one set of
knives C is mounted above the lower shaft c thus allowing the upper knives to
work into the lower; the correct adjustment of the said knives being obtained by
raising or lowering the sliding bush d through the medium of the hand wheel D.
For the purpose of preventing the paper from being carried round the spindles
after being cut and for leading the shavings to the front rollers E a plate
employed provided with a number of holes f corresponding to the number of
washers upon the lower spindle c', within which are secured brass, copper or other
wires f passing close to and between the knives thus leading the shavings away
and keeping the top and bottom cutters always clear; the said wires being either
left free towards their forward ends or supported in any convenient manner.
is
The paper, which may be fed into the machine in sheets or from the reel, is
conveyed to the cutters by means of two rollers E' mounted in the bearings e
in such a manner that the distance between them can be regulated by the screw e¹.
After passing through the cutters the strips or shavings are again conveyed by
the rollers E on to the back table of the machine on which there is erected a dead
knife H with gearing for another rotary cutter G for the purpose of cutting the
strips or shavings from the web into any length required.
.. This latter consists of a shaft or spindle G¹ provided with discs g upon which
are secured T, angle or other shaped strips of metal. To these metal strips
are secured the knife blades q₁ which are made adjustable... The said knife
blades g, are secured at an angle so as to act as a shear when in contact with the
dead knife H.
Smootheners H¹ consisting of strips of angle, T or other iron may also be
secured upon the-discs a to fold or crease the shavings prior to being cut

page_text: The shavings or strips then drop on to an endless canvas sheet J mounted upon
rollers j, and are thus conveyed to a receptacle ready to be packed up.
The foregoing knives and rollers are operated by means of spur wheels
driven from the main shaft K; the rollers of the endless canvas band being
rotated by a belt and pulleys also driven from the main shaft.
It will be seen from the foregoing that in order to cut, say a sheet of paper 30"
wide into strips or shavings of an inch in breadth, 120 knives would be required
on the top and 120 knives on the bottom shaft or spindle the number varying
according to the width of shavings required.
The washers C may be of cardboard, rubber, metal or other substance.
The reel or reels of paper may be attached behind in the machine or retained
in position apart from it; the machine being constructed to cut a single or any,
number of sheets up to twenty or more at one time.
In place of spur pinions being employed for driving as shewn, we may employ
any arrangement of pinions, wheels, pulleys, springs and cams which may be
found convenient.
The machine may be made adjustable so as to cut any width of strip or
shaving.
The machine may also be conveniently employed for the cutting of recording
tapes used in telegraphic apparatus.
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:-
1. The machine for cutting paper into strips or shavings, substantially as here-
inbefore described and shewn in the accompanying drawings.
2. In a machine for cutting paper into strips or shavings the arrangement of
the upper and lower rotary cutters C, C working into each other, substantially.
as hereinbefore described, and shewn in the accompanying drawings.
3. In a machine for cutting paper into strips or shavings, the combination of
the dead knife H and rotary cutter G with the rotary cutters as claimed in Claim 2,
substantially as and for the purpose hereinbefore described and shewn in the
accompanying drawings.
4. In a machine for cutting paper into strips or shavings, the arrangement
whereby the shavings are led to the rollers feeding the dead knife and cutter and
prevented from being carried round the spindles between the knives, substantially
as herein before described and shewn in the accompanying drawings.
5. In a machine for cutting paper into strips or shavings the arrangement
whereby the shavings are conveyed to the packing receptacle after being cut into
the desired lengths by the dead knife and cutter, substantially as hereinbefore
described and shewn in the accompanying drawings.
