RING TRAVELER ANDy SUPPORT THEREFOR Filed Sept. 6, 1955 vPatented June 12, 1934 UNITED STATES PATENT QFFICE RING TRAVELER AND SUPPORT THEREFOR George H. Gilligan, Providence, R. I., assigner toV U. S. Ring Traveler Company, a corporation of Rhode Island My invention relates to ring travelers for use upon the rings of spinning and twisting machines.

The essential objects of my invention are to insure an upright position of the traveler in its course around the ring; to avoid gripping contact and consequent excessive wear; to induce a smooth undeviating and gliding horizontal movement of the traveler as it describes its path; and to effect these ends in a simple and inexpene sively formed structure.

Other objects and advantages will be apparent to those skilled in the art by an inspection of the following specification.

My invention consists, therefore, in the parts and combinations of parts which fall within the scope of the appended claims.

In the accompanying drawing,

Figure l is a plan view of my traveler and of a ring and holder by which the traveler is supported,

Figure 2, a section taken on line 2 2 of Fig-v ure 1,

Figure 3, a fragmentary section taken on line 3 3 of Figure 2,

Figure 4, a perspective view of my traveler,

Figure 5, a section taken on line 2-2 of Figure 1 omitting certain of the rings, and showing in side elevation a modiiied form of my ring,

Figure 6, a fragmentary section on line 6 6 of Figure 5,

Figure 7, a perspective View of a modified form of traveler.

Similar reference characters indicate similar parts throughout the views.

My traveler l2, the material of which may be of any usual or preferred cross section, includes the usual upright irregular shank 14 and vertical inwardly directed upper and lower horns 16 and 18 respectively. Integral with the interspaced ends of the horns 16 and 18 are parallel guide or bearing lingers or lugs 20 and 22 respectively, each projecting in the direction opposite to that of the other, and, therefore, at right angles to the common plane of the shank and horns.

The traveler is herein shown in operation upon a structure including an expansible annular ring holder 24, split as at 26, and adapted to be sup ported in a rail opening by an external shoulder 27. A plurality of vertically interspaced rings 30 are supported one above the other in the holder by flat annular projections or lips 32 upon the holder which enter annular slots 33 in the sides of the rings.

In this multiple ring structure vertical rings of different lengths are employed according to the different counts of the yarn beingoperatedon. In this instance the traveler 12 which is of a length to embrace two rings is employed, namely the two uppermost rings. By reference to Figures 2 and 3 it will be observed that the guide or bearing fingers 20 and 22 slidably bear respectively upon the top face of the upper projection 32, and

the bottom face of the lower projection. It is evident that the lingers prevent any tilt of the t5 traveler in the direction of its movement.

In Figures 5, 6 and 7 is shown a modied form of my invention embodied in the arched type of traveler 35. In this construction the shank 37 is in a vertical plane but in shape is regularly curved or arcuate, having vertical upper and lower terminal horns 39 and 41 respectively, interspaced a shorter distance than the horns of traveler 12.

The lateral guide or bearing lugs 43 and 45 upon the ends of the horns 39 and 41 respectively are severally oppositely directed and parallel with each other.

The traveler 3'? is purposed for use upon a single ring and is shown applied in Figure 5 to the i forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. I n combination, an annular ring holder, a

plurality of vertically interspaced annular projections upon the holder, rings upon the projections, and a ring traveler comprising a vertical shank extending at its upper end over the topmost ring, and extending at its lower end below a lower ring, a downwardly directed horn upon the upper end of the shank, an upwardly directed horn upon the lower end of the shank, a lateral lug upon the upper horn slidably engageable with the topmost annular projection, and a lateral lug upon the lower horn slidably engageable with the projection associated with said lower ring.

2. In combination, an annular ring holder, an annular projection upon the holder, a ring upon the projection, and a ring traveler comprising an upright curved shank extending above and below the ring, a downwardly directed horn upon the upper end of the shank, an upwardly directed horn upon the lower end of the shank, a lateral lug upon the upper horn slidably engageable with the top of the projection, and a lateral lug upon the lower horn sldably engageable with the bottom of the projection.

3. In combination, an annular ring holder, an annular projection extending transversely from the inner surface thereof, a ring seated on said projection, and a ring traveler comprising a shank and horns at the ends of the shank directed toward each other, one of said horns having a projection at the end thereof extending laterallyY sidewise and seating on said annular projection.

4. In a ring traveler, a shank having its upper portion oiset rearwardly, theends of the shank terminating in horns extending forwardly and directed towards each other, one of said horns having a lug extending from its end and laterally therefrom.

5. In a ring traveler, a shank having its upper portion offset rearwardly, the ends of the shank "terminating in horns extending forwardly and -horns having-a lug extending from its end and laterally therefrom, said lugs being oppositely s directed.

A8. In a ring traveler, a curved shank, the ends of the shank terminating in horns extending forwardly and directed towards each other, each of said horns having a lug extending from its end and laterally therefrom, said lugs being oppositely directed.

GEORGE H. GILLIGAN.
