Improvements in Machines for Cutting Cloth and the like.
A communication from RICHARD SCHOFIELD, of the Town of Paris, in the County
of Brant, in the Province of Ontario, Canada, mechanic.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention to be as follows:-
The object of the invention is to devise a simple machine for cutting textile and
other fabrics, which may be moved with perfect freedom, and which will not be clogged
in its operation; and it consists, essentially, of a disc having a knife-edge and fastened
to a spindle connected to and deriving motion from a flexible driving shaft, the said
spindle being journalled in a bracket provided with a handle and attached to a foot to
support the bracket and extending along the surface of the disc forms a support for
the fabric being cut by the said disc, substantially as hereinafter more particularly
explained.
In carrying the invention into practice there is provided a disc having a knife-edge
and rigidly fastened to a spindle which is supported in a suitable journal or journals
formed on a bracket provided with a handle.
The bracket is adjustably connected to the standard so that the foot which extends
along the surface of the disc may be adjusted with relation to the said disc so as to
support the cloth at the point where the cutting-edge of the disc will best act upon it.
There are of course various ways of forming this adjustable connection, one of which
consists of a bolt which is connected to the standard and passes through a vertical
slot in the bracket and is provided with a suitable clamping-nut. The bottom of the
foot rests upon a plate in such a position that the projecting ledge formed on the said
plate shall extend past the edge of the disc and form a support for the cloth on the
side of the disc opposite to that on which the cloth is supported by the foot. The
beforementioned plate is adjustably connected to the foot by a pinching-screw passing
through a slot in the foot and into the plate below it. This provision for the adjust-
ment of the plate is made in order that the ledge thereon may readily be adjusted
with relation to the disc so as to support the cloth at the point where the cutting
edge of the said disc will best act upon it.
Instead of making the ledge solid with the plate and making the said plate adjust-
able, the same effect could be produced by making the plate a portion of the foot and
making the projecting ledge adjustable upon the edge of the said foot.
The before mentioned disc-carrying spindle is connected to a flexible shaft which
is of the usual description and is connected at its other end to another spindle
suitably journalled in a bracket and connected to the motor from which power is to
be derived.
In order to support the flexible shaft and prevent its weight from interfering with
the free movement of the cutter during the time that it is in use an elastic band or
spiral spring is attached at one end to the flexible shaft and at its other end to some
elevated point.
When in use the edge of the cloth to be cut is placed over the toe of the foot
attached to the plate which rests on a suitable table and the disc which is caused torevolved
at a high speed is then pushed by the operator holding the handle in the direction
required, the cutting edge of the disc cutting the cloth into the required pattern. The
shaft which is connected to the disc-carrying spindle being flexible and preferably sup-
ported by an elastic band does not impede in the slightest degree the free movement of
the cutter.

Improvements in Machines for Cutting Cloth and the like.
A communication from RICHARD, SCHOFIELD,, of the Town of Paris, in the County
of Brant; in the 'Province of Ontario, Canada, mechanic.
I,
ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.L.M.E.,
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:-
The object of the invention is to devise a simple machine for cutting textile and
other fabrics, which may be moved with perfect freedom and which will not be clogged
in its operation; and it consists, essentially, of a disc having a knife edge and
fastened to a spindle connected to and deriving motion from a flexible driving shaft,
the said spindle being journalled in a bracket provided with a handle and attached to
a foot to support the bracket and extending along the surface of the disc forms a
support for the fabric being cut by the said disc substantially as hereinafter more
particularly explained.
Fig. is a perspective view of this improved cutter.
Fig. 2 is a detail of the adjustable foot-plate.
Fig. 3 is a general view showing the cutter in operation and the manner of driving
and supporting its flexible driving shaft.
Fig. 4 is a cross section through the standard and hood.
Fig. 5 is a perspective detail of an alternative form of foot-plate.
A is a disc having a knife-edge and rigidly fastened to the spindle B. This
spindle is supported in a suitable journal or journals formed on the bracket ( which
is provided with a handle D.
E is a standard connected to or forming part of the foot F. The bracket C is
adjustably connected to the standard E so that the foot F which extends along the
surface of the disc may be adjusted with relation to the said disc so as to support
the cloth at the point where the cutting-edge of the disc A will best act upon it.
There are of course various ways of forming this adjustable connection. In the
drawing I show one way which consists of a bolt G connected to the standard E and
passing through a vertical slot in the bracket C is provided with a suitable clamping-
nut H. The bottom of the foot F rests upon the plate I in such a position that the
projecting ledge a formed on the plate I shall extend past the edge of the disc A and form a
support for the cloth on the side of the disc opposite to that on which the cloth is
supported by the foot F. The plate I is adjustably connected to the foot F by a
pinching screw J passing through a slot b in the foot F and into the plate below it.
This provision for the adjustment of the plate 1 is made in order that the ledge a
may readily be adjusted with relation to the disc A so as to support the cloth at the
point where the cutting edge of the said disc will best act upon it.
Instead of making the ledge a solid with the plate I and making the said plate
adjustable the same effect could be produced by making the plate I a portion of the
foot F and making the projecting ledge a adjustable upon the edge of the said foot
(see Fig. 5).
On reference to figure 3 it will be noticed that the spindle B is connected to a
flexible shaft K which is of the usual description and is connected at its other end
to a spindle L suitably journalled in a bracket and connected to the motor from which
power is to be derived.
In order to support the flexible shaft K and prevent its weight from interfering
with the free movement of the cutter during the time that it is in use an elastic band
or spiral spring M is attached at one end to the flexible shaft K and at its other end
to some elevated point; as indicated.
From the foregoing description the mode of operation may be readily understood. The
edge of the cloth to be cut is placed over the toe of the foot F attached to the plate I
which rests on a suitable table. The disc A is caused to revolve at a high speed and

page_text: is pushed by the operator holding the handle D in the direction required the cutting
edge of the disc cutting the cloth into the required pattern. The shaft K being
flexible and preferably supported by the elastic band M does not impede in the slightest
degree the free movement of the cutter.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent I declare that what I claim is ;-
