MACHINE FOR CUTTING CLOTH.

SPECIFICATION forming part of Letters Patent No. 400,603, dated April 2, 1889.

Application filed February 27, 1888. $eria1No. 265,397. (No model.)

To aZZ whom it may concern.-

Be it known that I, RICHARD ScHoFIELD, mechanic, of the town of Paris, in the county of Brant, in the Province of Ontario, Canada, have invented a certain new and useful Machine for Cutting Cloth, of Which the following is a specification.

The object of the invention is to devise a simple machine for cutting textile and other fabrics, which may be moved with perfect freeeration; and it consists in the peculiar comand adaptation of parts hereinafter more particularly described, and thendefiuitelypointed out in the claims.

Figure 1 is a perspective view of my improved cutter. Fig. 2 is a detail of the adj ustable 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 view, partly in section, of an alternative form of foot-plate."

A is a disk 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 C, 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 disk A, may be adjusted with relation to the said disk, so as to support the cloth at the point where the cutting-edge of the disk A will best act upon it. There are of course various ways of forming this adjustable'connection. In the drawings 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, isprovided 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 disk A and form a support for the cloth on the side of the disk opposite to that on which the cloth is supported by the "foot F. The

plate I is adj ustably connected to the foot F by a pinching-screw, .T, passing through a slot, 12, in the foot F and into the plate below it. This provision for the adjustment of the plate I is made in order that the ledge a may readily be adjusted with relation to the disk A so as to support the cloth at the point where the cutting-edge of the said disk will best act upon it.

Instead of making t e ledge a solid with the plate I, and making the said plate adj ustable, the same effect could be produced by making the plate I a portion of the foot F, and making the projecting ledgea adjustable upon the edge of the said foot, as shown in Fig. 5.

On reference to Fig. 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 journaled 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, I attach, by means of a suitable swivel, an elastic band or spiral spring, M, 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 maybe readilyunderstood. 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 disk A is caused to revolve at a high speed and is pushed by the operator holding the handle D in the direction required, the cutting-edge of the disk 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.

What I claim as my invention is- 1. A flexible shaft, K, connected at one end to a spindle, L, deriving a rotary motion from some suitable motor, and at its other end to a spindle, B, of the disk A, and suitably supported, as described, in combination with the elastic band M, arranged to support the flexible shaft K, substantially as and for the purthe cloth is supported by the said foot, subpose specified. stantially as described.
