UNITED STATES EPEEAIM B. WELLS, 0E NEW YORK, N. Y.

IMPROVEMENT IN MACHINES FOR CUTTING CLOTH.

I Specification forming part of Letters Patent No. 117 ,352, dated July 25, 1871.

To all whom it may concern:

Be it known that I, EPHRAIM B. WELLS, of New York city, in the county and State of New York, have invented a new and Improved Machine for Cutting Cloth; and I do` hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

Figure 1 represents a side elevation of my im! proved cloth-cutting machine. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a horizontal section of the Same.

Similarletters of reference indicate correspond- I ing parts.

My invention consists in a new combination of instrumentalities to form a cloth-cuttin g machine, as hereinafter described and subsequently pointed out in the claim.

A in the drawing represents the frame of my improved cutting-machine. B C are two drums mounted, respectively, upon horizontal shafts a and b, which han-g in horizontal frames c and d, pivoted to an upright post e of the main frame A. The drums B C are in line with each other, and serve to hold an endless band o r belt, D, which is made of thin metal, with projecting lancetshaped cutters ff that are sharpened at one or both edges. The lower shaft b is, by a belt or gearing, connected with the drivin g-shaft E, hung in A, to receive rotary motion therefrom. rIhe back ends of the frames c d are connected with each other by a rod, F, carrying a nut, y, and a spring or piece of rubber, h, under the nut. AVllhe nut and rod serve to hold-the band tense, and the spring gives it the requisite degree of elasticity. From the post c projects an arm, i, carrying a grooved wheel, j, in which the band is guided, as shown, to prevent the swinging of the same. G is the platform on which the cloth is supported. This platform is of circular form, as Shown in Fig. 3, and is surrounded by an annular platform, H, which is, by wheels k k, supported on a lower projecting flange, m, of the platform l G, so that H can be turned aroimd G. Both platforms G and H are slotted to permit the removal and application of the band.

The cloth to be cutis placed upon the platform G and fed against the continuous cutter in the requisite direction; it then arrives Yin rear of the cutter, where it will, in part, be supported Y by the ring H, and can readily be brought in front of the cutter by turning the ring. This avoids, to a great extent, the labor of bodily carrying the cloth to the front, such labor being, at times, considerable when the cloth in its several thicknesses weighs one hundred pounds or more. Directly at the sides of the cutter are fastened to the platform G small metal plates 'l l, which have a slight lateral play, being slotted where the fasteningpins pass through them. These plates line the slot aforementioned in the platform just in line with the cutter, and yield slightly to the side whenever some cloth is dragged down into the Slot by the cutter. They therefore prevent the clogging of the machine.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The pivoted frame c d, rod F, spring h, drums B C, endless band`cutter D f, adjustable guideplates l l, stationary table G, and movable table H, all combined, arranged, and operating as and for the purpose described.
