SOLOMON RICH, OF JOPLIN, MISSOURI.

MACHINE FOR CUTTING OUT GARMENTS.

SPECIFICATION forming part of Letters Patent- No. 291,776, dated January 8, 1884.

Application filed October 12, 1883.

To all whom it may concern.-

Be it known that I, SOLOMON RICH, of J oplin, in the county of Jasper and State of Missouri, have invented a new and useful Improvement in Machines for Cutting Out Garments; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical section through the line x w of Fig. 2, looking in the direction of the arrow. Fig. 2is avertical section through the line y y of Fig. 1, looking in the direction of the arrow; and Fig. 3 is a cross-section on a large scale of the endless flexible belt-knife. Fig. 4 is a detail of a plate, H.

The object of my invention is to provide a machine for cutting cloth for garments, which shall out the material in a continuous operation, and through several thicknesses, thus cutting several patterns at once, and doing the work much more expeditiously than by any other machine in the usual way.

To this end my invention consists in the com bination, with a cutting-table, of an endless flexible knife-belt passing through slots in the table and around a pulley above the table, and another below it, against which belt-cutter the material is advanced as it is cut, and a pressing-roller for keeping the material free from wrinkles or plaits as it is cut; and in means for guiding the belt-knife, as will be fully described hereinafter.

In the drawings, B represents the stationary table-surface, to which may be hinged an adjustable leaf, 0, for holding large pieces of material, and which may be dropped down to give closer access to the cutter. This hingeleaf, however, is not necessary, and in many cases will be dispensed with. Underneath the table, in suitable bearings upon the floor A, is arranged a driving-pulley, D, which re ceives power from any suitable source, and transmits it through a belt, J, to another smaller pulley, E, arranged in bearings upon the floor A. On the same shaft with this pulley E is a pulley, I, having a flanged periph- (No model.)

ery, around which passes a flexible belt-knife,

'i, which passes through two slots, j j, in a plate, H, on the table, and extends around a pulley, I, above the table, which has a flange like the pulley I below. The flexible beltknife 2' has one edge very sharp, (see Fig. 3,) and its other or rear edge fits against the flange of the pulleys I I, and in passing through the plate H also bears against backthrust rollers a, which prevent the knife from being strained out of its path when the material is pressed against the knife. The upper flanged wheel, I, is journaled in a supporting-frame, K K, which overhangs the table a sufflcient distance to allow plenty of room for turning the material. This frame is composed of two metal rods, the terminal ends of each of which rods are firmly secured to the table by being screw-threaded and having nuts above and below the table clamping the bent rods to the latter.

Instead of using a frame for sustaining the pulley I like that just described, this pulley may be swung in a frame attached to the ceiling. G is a spring holding at its lower end a roller, G, which bears upon the cloth .on the table in front of the belt-knife and holds it flat and clear of wrinkles or plaits. This springis attached to the table at one end, and is then bent up with a gradual curve, then down and around, and at its other end is jointed to a link-rod, G through which linkrod the spring passes, and which link-rod serves to stiffen and brace the spring and its roller against lateral motion, still allowing, however, a free up-and-down movement for said roller. Instead of supporting the roller G and the springs upon the table, they may be attached to the ceiling or secured overhead.

I am aware that an endless knife-belt has been arranged to pass around pulleys above and below a work-table, and I do not claim this feature, broadly.

Having thus described my invention, what I claim as new is- 1. The plate H, with slots j j and back thrust roller a, in combination with the table,
