SPINNING-RING.

SPECIFICATION formingpart of Letters Patent N 0. 714,966, dated December 2, 1902. Application filed February 20, 1901. Serial No. 48,122. (No model.)

To ttZZ whom, it may concern:

Be it known that 1, MICHAEL E. SULLIVAN, of New Bedford, in the county of Bristol and State of Massachusetts, havein vented certain 5 new and useful Improvements in Spinning- Rings, of which the following is a speciflcation.

This invention has relation to spinningframes, and more particularly to rings therefor, having for its object to provide certain improvements therein whereby the friction on the end of the traveler will be reduced to permit the more rapid rotation of the bobbin and a consequent increase in the production of the frame.

In carrying out my invention I employ a fixedi. e., non-rotary-ring, but interpose between it and the outer end of the traveler a movable race or traveler-support. This support is illustrated as in the form of a flat ring which encircles the spinning-ring and which rests loosely upon antifriction members, so that when the traveler is thrown outward and downward by centrifugal action during the rotation of the bobbin its end rests upon the rotary support, which is free to rotate with it, and thereby relieve it from frictron.

On the accompanying drawings,which illustrate one embodiment of my invention, Figure 1 represents a plan view of a ring embodying my invention. Fig. 2 represents a vertical section through the same when the bobbin and traveler are at rest. Fig. 3 represents a similar section, but shows the position of the traveler when moving at high speed.

Referring to the drawings, a indicates a spinning-ring having the external flange a 0 and the internal flange a which constitute races for the traveler b. A holder 0, which is adapted for attachment to the rail, is countel-bored to receive the ring, the latter having a snug friction fit therein and projecting a short distance thereabove to leave a groovelike space between the flange a and the upper face 0 of the holder.

When the traveler is moving swiftly around the race during the rapid rotation of the bobbin, the outer end I) thereof is forced outward and downward from the race a by contrifugal action, as is well known, and engages the periphery of the ring-body. Consequently both ends of the traveler are in engagement with the ring, and the frictionengendered thereby increases with the speed of rotation of the bobbin. This has hitherto limited the speed at which the traveler could trar'el without becoming annealed and burned, and a relativelylow production ofyarn upon a frame has been the result. I find, however, as pro viously stated, that by interposing between the periphery of the ring and the end of the traveler a movable race or traveler-support that the friction may be reduced to such an extent as to permit a relatively great increase in the speed ofthe traveler without a material increase in friction.

The traveler support in the illustrated embodiment of the invention consists of a fiat ring d, which loosely encircles the ring a and lies between the flange a and the face of the ring-holder. A space is left between the upper face of the support and the under face of the said flange a, into which the inturned end I) of the traveler projects and which is greater than the thickness of the traveler to permit one side of said end of the latter to leave said flange a, as shown in Fig. 3, and the other side to engage the movable race. The support or movable race is free to move laterally in any direction to a limited extent, and it rests upon antifriction-balls e, placed loosely in sockets 0 formed at regular intervals in the face of the holder 0. Each ball 6 rests upon another ball 6' and projects above the face 0, as shown, to maintain the support above and out of contact with said face.

In operation the initial rotation of the bob bin causes the traveler to move slowly around the race; but as its speed increases the end I) of the traveler is thrown downward until it rests upon the rotatable race. The engagement of the traveler with the support or rotatable race causes the latter to rotate slowly 5 at first and then with increasing speed until it appears to be moving in unison with the traveler.

Having thus explained the nature of the invention and described a way of construct- I00 ing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is- 1. In combination, a non-rotary spinningring having two flanges forming a travelerrace, and a rotatable traveler-support.

2. In combination, a spinning-ring having two flanges forming a traveler-race, a ringholder, and a movable traveler-support.

3. In combination, a spinning-ring having oppositely-extending flanges forming a traveler-race, and a rotatable traveler-support encircling said ring.

4. In combination, a non-rotary spinningring, having two oppositely-extending flanges forming a race, and a rotatable traveler-support encircling the ring below said race.

5. In combination, a spinning-ring having two oppositelyextending flanges forming a traveler-race and means supported independently of the traveler for reducing the friction between the traveler and the ring.

6. In combination,a non-rotary ring having oppositely-extending flanges forminga traveler-race, and means supported independently of the traveler, and rotatable therewith for reducing the friction of the traveler.

7. In combination, a non-rotary ring, having oppositely-extending flanges forming a traveler-race, a traveler, and a flat travelersupport rotatable with the traveler but located below the end of said traveler.

8. In combination,an inner non-rotary ring,

a traveler, and an outer rotatable ring disposed in such relation that the under side of one end of the traveler engages one ring and the other end of the traveler engages the other ring.

9. In combination, a non-rotary ring having a race, a traveler, a rotatable race located below the end of the traveler, the traveler being moved by centrifugal force into engagement with the movable race when moving at high speed.

10. In combination, a fixed ring having inner and outer races for the ring, and a surrounding rotatable ring having a traveler-race adjacent one of the races of the fixed ring.

11. In combination, a fixed ring having outer and inner races for the traveler, and a rotatable ring having a race for the traveler, and a traveler, the latter being caused to engage the movable race by centrifugal force.

12. In combination, a ring having flanges 15. In combination, a fixed ring, a traveler adapted to be engaged on its inner side by said ring, and a movable bearing to cooperate with the outer and under side of the traveler.

16. In combination, a ring having an external flange against which the traveler may bear, a ring-holder, and a rotatable member adapted to cooperate with the traveler, interposed between said flange and said holder.

17. In combination, a fixed ring having an external flange, a rotatable member below said flange, and a traveler having an inturned end adapted to alternately engage the flange with one side of its said end and the member with the other side of its said end.

In testimony whereof I have aflixed my signature in presence of two witnesses.
