United States Patent 3,036,548 SIZING ATTACHMENT FOR CLOTH CUTTING MACHINES Lester J. Ulrich, Bufialo, N.Y., assignor to Eastman Machine Company, Buffalo, N.Y. Filed Nov. 25, 1960, Ser. No. 71,490 4 Claims. ((11. 118-38) This invention relates to motor driven cloth cutting machines provided with reciprocatory knives.

When cloth or other woven materials is cut, the cut edges of the material tend to ravel and stitching or binding of the same is generally necessary before the material is sewn into a garment or other article to prevent ravelling. It is also possible to prevent ravelling by treating the seam with a suitable sizing material of a composition which does not wash out or become removed during dry cleaning. However, it is somewhat time-consuming to apply the sizing material by hand to the goods to prevent ravelling at the cut edges.

It is consequently an object of this invention to provide a cutting machine with means for applying a sizing liquid to the edges of a plurality of sheets of a lay of cloth at one time immediately after cutting the same.

It is also an object of this invention to mount on the cutting machine a container for the sizing liquid and also a discharge device from which the sizing solution is discharged immediately after the knife has passed through the material.

In the accompanying drawings:

FIG. 1 is a front elevation of a cutting machine having applied thereto a sizing liquid-dispensing means embodying this invention.

FIG. 2 is a side elevation thereof.

FIG. 3 is a transverse, sectional plan view thereof on an enlarged scale on line 33, FIG. 2.

FIG. 4 is a side elevation of the standard detached from the machine to which my improvements are applied.

My improvements may be applied to any desired type of cloth cutting machine having a vertically reciprocating knife. The machine shown in the drawings by way of example includes a base 7 formed to rest on and be moved about on a table which supports the lay of material to be cut. This base, in the use of the machine, is moved underneath the material.

An upright standard 8 is rigidly secured to the base and extends upwardly therefrom and supports the frame 9 of an electric motor 10 which reciprocates the knife 11 in a vertical guide slot at the front of the standard 8. The standard may be secured to the base 7 in any suitable manner. For example, the standard may be provided at its lower end with an enlarged foot portion 12 which is rigidly secured to the base 7 by a screw threaded connection, as shown in FIG. 4. The cutting machine is provided with the usual handles 13 and 14 by means of which it is guided during its movement to effect cutting.

In order to apply the sizing solution correctly to the edges of the material of the lay immediately after it has been cut, I provide at the rear end of the standard 8 a tube or pipe 15 rigidly secured to the rear of the standard. The tube, of course, is of materially smaller diameter than the thickness or transverse dimension of the standard so as not to interfere with a passage of the standard through the material after the same has been cut. The lower end of this tube may be soldered or otherwise secured at 16 to a foot part 12 of the standard. The standard 8 is preferably provided at its rear edge with a recess 24) into which the front portion of the tube 15 fits and the tube is securely held in this recess in any suitable manner, for example, by providing the upper portion of the tube seams 21 of solder or the like which firmly connects the upper portion of that part of the tube which extends along the rear of the standard. The portion of the tube between the welds or soldered seams 21 and the connection 16 at the base of the standard is provided at opposite sides thereof with a large number of small openings 24 through which the sizing solution is directed to the edges of the material which has been cut. By seating the tube within the recess in the standard none of the material whihch has been cut will become lodged in the space between the tube and the standard.

A sizing solution may be supplied to the distributing tube 15 in any suitable manner, and in the construction shown by way of example, the upper end of the tube 15 may be bent to form an integral extension 25 which connects wtih a suitable reservoir or tank 27 for the solution. This tank may be mounted on the cutting machine in any suitable or desired manner, and in the construction shown the tank is shown as supported by means of a bracket 26 secured to the motor frame and to the tank. The tube 25 is provided with a valve 28 which may be opened at will by the operator to admit sizing solution to the dispensing portion 15 of the tube. This valve may be of any suitable or desired form which can be easily actuated by the operator. The valve 28 is connected by tubing 30 with the lower portion of the tank or reservoir 27.

In the use of my improvements, when the operator starts a cut, he opens the valve 28 to admit sizing solution to the distributing pipe 15, whereupon he proceeds with the cutting in the usual manner. After completing a cut, he can close the valve 28. It will be noted that if it is desired to make cuts without applying a sizing material to the cut edges, it is merely necessary for the operator to keep the valve 28 closed, since none of the sizing equipment interferes with the ordinary use of the machine.

By means of my improvements as deescribed, no separate operation for preventing ravelling of the material is necessary since the spraying of the edges of the cotton fabric is effected simultaneously with the cutting of the same.

It will be understood that various changes in the details, materials and arrangements of parts which have been herein described and illustrated in order to explain the nature of the invention may be made by those skilled in the art Within the principle and scope of the invention as expressed in the appended claims.
