Be it known that 1, CHARLES E. Taow- BRIDGE, of Whitinsville, in the county of Worcester and State of Massachusetts, have invented an Improvement in Machines for Mannfacturing Rings for SpinningMachines; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

The invention has particular reference to an organization of mechanism for simultaneously forming the inner and outer grooves of a spinning-machine ring. For this purpose 1 use, in combination with a rotary chuck for holding and rotating the ring-blank, two cutters at the or shafts fixed in a carriage having a capability of lateral movement in a plane parallel to the end or face of the ring, the cutters being in the plane of the ring, and so disposed that when one of them (in non mal position) is against the outside of the ring, the other is against the inner surface of the ring and diametrically opposite to the other, and so that if the carriage be then moved up, being rotated,) the two cutters will simultaneously form the two grooves, the first forming the outer groove an the other the inner groove.

The invention consists, primarily, in this method of forming the two grooves simultaneously, and in the two cutters so combined with the rotary chuck that, as they are fed forward, they simultaneously form the two grooves.

The drawing represents a machine embodying my construction.

Figure 1 shows the mechanism in plan. Fig. 2 is a vertical longitudinal section of it. Fig. 3 is a side elevation of it. Fig. 4 is a transsection through the cutter-car rier.

A denotes the main shaft, supported in bearings B B on a bed, 0, and having'at its inner end a chuck, E, for holding the ring-blank F, the blank being shown as grooved. Before the chuck is a carrier, G, in which are fastened the shanks of the two groovingcutters I K,

each cutter being preferably a solid piece of steel, with a face the periphery or edge of which is of the exact form of the groove to be cut by it. The shanks are relatively so posi tioned and the cutting-faces so arranged that the two cutting'edges are at the exact distance apart of the outer surface of the blank from the inner surface of the blank diametrically opposite thereto, and they stand in the plane of the grooves to be cut, and against the blank when in position for the operation to commence. The cutter-carrier is mounted upon a carriage, L, to which it may be fastened by a clampscrew, M, and nut a, said nut sliding in grooves b c, and the carriage L is supported and slides upon another carriage, mounted on the bed 0, and made capable of movement toward and from the chuck. The cutters being set and the carrier being fastened to the carriage L, and the carriage N being then slid up toward the chuck until the cutters are in theplane in which the grooves are to be formed, rotation is imparted to the shaft A and its chuck. The carriage L being then moved up to press the cutters against the ring, said cutters pare away the material (as they. advance and the chuck rotates) until the grooves are both sunk to the proper dept The carriage L may be moved by hand; but the carriage is fed up by mechanism, for which purpose a vertical hand-wheel shaft, 0, may be journaled in a hearing at one end of the carriage N, said shaft having a cam, 01-, against which bears a projection, e, from the carriage L, the carriage being pressed against the cam by a spring, f, and being pressed forward against the stress of the spring by the cam (to bring the cutters into action) as the hand-wheel shaft is rotated. The spring f is placed in a chamber, g, and bears at one end carriage L, and at the opposite end against a piece, h, projecting from the carriage N.

To make the operation wholly automatic the hand-wheel shaft and the chuck-shaft may be connected, for which purpose the shaft 0 is shown as having a worm-wheel, m, into which engages a worm, n, on a shaft, 0, supported in suitable bearings s, and connected by a belt, with the shaft A, the belt running over pulagainst the.
