SPINNING-RING.

SPECIFICATION forming part of Letters Patent No. 782,228, dated February 14, 1905.

Application filed March 30, 1904. Serial No. 200,706.

To (M7 whom if m/n HUI/087721:

Be it known that I, Tnnonoan P. FARMER, of Southwest Harbor, in the county of Hancock and State of Maine, have invented certain new and useful Improvements in Spinning Appliances, of which the following isa specification.

This invention has relation to ring-spinning machines, and has for its object to provide a mechanism to be employed in lieu of the ordinary ring and loose traveler in high-speed frames.

The invention has therefore for its object to provide a spinning appliance of the utmost simplicity and cheapness of construction.

Upon the accomymnying drawings, forming a part of this specification, and on which similar reference-letters indicate like parts or features, Figure 1 represents in perspective view a spinning appliance embodying the invention. Fig. 2 represents a vertical section through the same. Fig. 3 represents a horizontal section. Fig. represents a perspective view of the combined ring and traveler. Fig. 5 represents in plan view the blank of which the ring and traveler are constructed. Fig. 6 represents the antit'riction-bearing. Fig 7 represents in perspective view the metallic casing or holder in which the bearing is inserted.

The appliance consists, essentially, of three members-to wit, the casing or holder, the antifriction-bearing, and the combined ring and traveler. The casing or holder and the combined ring and travelerare especially designed to be stamped or died out of sheet metal, whereas the bearing is formed of some suitable antifriction material, such wood treated with oils. The casing itself consists of an annular portion a with a flat peripheral base-flange u. The annular or cylindrical portion a is formed with a plurality of ears or lugs If, which when the blank is first formed are upstanding, as shown in Fig. 7.

The bearing is indicated at .7). It is ring-like in form and is provided with a peripheral groove 6, the internal diameter of the bearing being such that it fits tightly around the annular portion a of the bearing, where it is held in place by bending down the ears or lugs upon it, as shown in Fig. 1. The peripheral groove 7/ is so formed that its bottom wall 1; is flat, whereas its upper wall 7) extends upwardly and then outwardly, the groove thus being substantially wedge-shaped.

The combined ring and traveler, as shown in Figs. 4 and 5, is not circular, being substantially elliptical in plan with its major axis considerably longer than its minor axis. It is formed with a tongue 0, which is bent into spiral form, so as to extend above the top of the bearing and constitute a hook through which the yarn is adapted to pass to the bobbin. The tongue 0 is in alinement with the major axis of the ring, and the portion of the ring which is opposite it is somewhat enlarged to form a counterbalance for the hook.

The diameter of the ring along its minor axis is substantially equal to the diameter of the inner wall of the groove, whereas its major axis is somewhat greater, so that the ring is adapted to be sprung into place in the groove and is also adapted to move along its major axis to a limited extent with relation to the bearing. The thickness of the ring is substantantially equal to the width of the groove [1 at the bottom thereof, the exact thickness of the ring not being shown upon the drawings, since it is necessary to exaggerateit somewhat for the purpose of illustration.

hen the parts are assembled together, the ring is adapted to rotate about the bearing, being so supported that the yarn-hook is capable of moving toward and from the axis of the bearing and also in a direction substantially parallel to the said axis. This provides for the yarn-hook yielding somewhat to unbalanced strains of the yarn. By thus mounting the ring in a wooden bearing properly treated with an oil composition it is adapted to rotate freely and without material wear.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it maybe made, or all of the modes of its use, I declare that What I claim is- 1. A spinning appliance comprising a hearing and a substantially elliptical rotary ring supported by said bearing, said ring beingfree to move bodily in the lines of its major axis but held against transverse movement along the lines of its minor axis.

2. A spinning appliance comprising a hearing, and an elliptical rotary ring encircling said bearing and having a yarn-hook located substantially in alinement with its major axis.

3. A spinning appliance comprising a nonmetallic annular bearing having a peripheral groove, a thin flat ring adapted to be sprung into said groove, said ring having a hook for the yarn, and a metallic casing or holder having a base-flange, an annular portion encircled by the bearing, and tongues or lugs projecting across the upper face of the bearing to hold it against the base-flange.

L. A spinning appliance comprising an an nular bearing having a peripheral groove, a

thin fiat ring adapted to be sprung into said groove, said ring having a hook for the yarn, and a holder having an annular portion extending into the opening in said annular bearing.

5. Aspinningappliancecomprisingaholder having a base-flange and an upstanding annular portion, an integral annular bearing encircling the annular portion of said holder and having a peripheral groove, and a resilient ring adapted to be sprung into said groove.

6. A spinning appliance comprising a holder having a base-flange and an upstanding annular portion, an integral annular bearing encirclingthe annular portion of said holder and having a peripheral groove, and a substantially elliptical ring adapted to be sprung into said groove.

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

THEODORE P. FARMER.
