CHARLES E. TROWBRIDGE, OF WVHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO THE WHITINSVILLE SPINNING RING COMPANY, OF SAME PLACE.

SPINNING-RING.

SPECIFICATION forming part of Letters Patent No. 438,660, dated October 21, 1890.

Application filed April 8, 1890. Serial No. 347,042. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES E. Tnow- BRIDGE, of VVhitinsville, county of WVorcester, State of Massachusetts, have invented an Improvement in Spinning-Rings, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention, relating to spinning-rings, has for its object to combine with a spinningring having an annular groove in its body a traveler-clearer having a portion inclined in the direction of the motion of the traveler on the race of the ring, the traveler-clearer having a spring-like portion to clasp the ring in its annular grooved part.

I have shown my invention as applied to that class of ring known as double race, it having an annular body with a raceway at each end thereof. The clearer shown consists of a piece of spring-wire bent to substantially surround the body of the ring, one end of the ring being inclined upwardly near the line of progress of the traveler, as clearly shown in application Serial No. 347,041. To retain the clearer in position upon the body of the ring, the latter has an annular projection which, as shown, is located substantially midway between the raceways, thus leaving a groove both above and below said annular projection to receive the spring part of the clearer, the said projection preventing the clearer rising from its true working position.

One part of my invention consists in a spinning-ring having an annular groove or depression at its outer side, combined with a traveler-clearer consisting of a portion inclined in the direction of the motion of the traveler on the race and having a spring-like portion to clasp the ring in the said annular groove to operate as will be described; also, in a ring composed of a body having raceways at its opposite ends and an annular projection between the said raceways, combined with a traveler-clearer consisting of a portion inclined in the direction of the motion of the traveler on the race, and having a springlike portion to clasp the ring between the said annular projection and one of the races thereof, as will be described.

Figure 1 in side elevation represents a ring embodying my invention with aclearer thereon. Fig. 2 is a section through one side of the ring. Fig. 3 is a view of the ring shown in Fig. 1,1ooking at the same from the right; and Fig. 4: is a modification showing a section of the ring wherein the body is provided with an annular projection at one side.

Referring to the drawings, the body of the ring has at each end a race, as a b, on which may run any usual traveler (Z, and substantially midway the said raceways the ring is provided with an annular projection b, leaving a groove above and below the same into which a part of the traveler-clearer may be sprung, according to which end of the ring is used uppermost.

The traveler-clearer herein shown consists of a piece of wire-like material 0, inclined upwardly in the direction of the movement of the traveler on the race of the ring to operate as described in my application Serial No. 347,041, the said upwardly-inclined portion being part of a spring-like clasp c,which partially embraces the ring entering the groove thereof between the projection and the under race upon which the traveler is not running.

The ring will be held in any usual ringholder, which latter will be attached to the rail in any usual manner.

The annular projection b may be made upon the outer and inner sides of the body of the ring, as in Fig. 2, or may be solely upon the outer side of the ring, as in Fig. 4, the said annular projection, whether upon one or both sides of the ring, in addition to keeping the traveler-clearer in proper position with relation to the ring, also serving to strengthen the ring, so that the body portion thereof is less liable to spring when hardening.

I claim 1. A spinning -ring having an annular groove or depression at its outer side, combined with a traveler-clearer consisting of a portion inclined in the direction of the motion of the traveler on the race, and having a spring-like portion to clasp the ring in the said annular groove, to operate substantially as described.

2. A ring composed of a body having raceways at its opposite ends and an annular projection between the said raceways, combined In testimony whereof I have signed my with a traveler-clearer consisting of aportion name to this specification in the presence of inclined in the direction of the motion of the two subscribing Witnesses.

traveler on the race, and having a spring-like CHARLES E. TROWBRIDGE. 5 portion to clasp the ringbetween the said an- Vitnesses:

substantially as described. ARTHUR F. WHITIN.
