To aZZ whont it ntay concern.-

Be it known that 1, DAVID HARRINGTON, a citizen of the United States, residing at Vorcester, in the county of W'orcester and Commonwealth of Massachusetts, have invented new and useful Improvements in Spinhing-Rings, of which the following is a specification, accompanied by drawings forming a part of the same, in which- Figure 1 represents a top view of a spinning-ring embodying my invention. Fig. 2 is a sectional view on line 2 2, Fig. 1. Fig. 3

My invention relates to the spinning-ring and traveler employed in ring-spinning; and it has for its objects to reduce the Wear upon the operating parts and to decrease the friction between the fixed spinning-ring and the rotating traveler, whereby a greater speed can be attained than hitherto possible with the travelers now in use; and I attain these objects by means of the construction and arrangement of parts as hereinafter described, and set forth in the annexed claims.

My present invention comprises four features which, so far as I am aware, are new in the practice of ring-spinning.

The first novel feature of my invention con- 'sists in employing a traveler capable of rotating in a peripheral track on the fixed spinning-ring, said traveler consisting of an integral ringloosely fitting the peripheral track, so that by a proper counterbalancing of the forces applied to the traveler it will be caused to rotate around the peripheral track, but out of contact therewitl The second novel feature consists in counterbalancin g opposite sides ofthe traveler by the employment of a hook or eye upon one side to engage the yarn and a counterweight upon the opposite side in order to overcome the centrifugal force of the hook or eye when the traveler is rotated at a high speed.

The third novel feature consists in the peculiar construction of the spinning-ring in telescopic parts, with an external groove between them to enable the traveler to be readily applied to and removed from its peripheral track, and the fourth novel feature consists in confining that portion of the peripheral track which is subject to wear to one of the telescopic sections only of the spinningr ng.

The above-enumerated novel features of my invention are hereinafter described, and illustrated in the accompanying drawings, in which- Figs. 1 and 2 show one form of construction embodying my invention relating to the fixed spinningring; Fig. 4, a modification, and Figs. 3 and 5 are views of two forms of travelers.

The spinning-ring is made in two sectionsan outer section A, provided with a flange B, adapted to be secured to the rail of a spin- 7o hing-frame, and an inner section (I, which in the present instance is adapted to telescope or slip within the section A and be held therein by frictional contact. The outer section A is preferably provided with an interior flange D, 7 5 upon which the lower edge of the inner section 0 rests. The inner sectionOis provided at its upperedge with an outer flange E, which overhangs the outer section A, forming a pcripheral track between the flanges B and E for a rotating annular traveler. In that form of construction shown in Fig. 2 a space is left between the flange E and the upper edge A of the outer section in order to expose the periphery of the inner section to the action of the rotating traveler, and thereby confine the wear to the inner section 0 of the ring, which can be replaced without removing the outer section A from the rail of the spinning-frame.

Amodificationofthespinning-ringisshown c in Fig. 4, in which the vertical wall of the outer section A is made thick enough to form a shoulder J, with an intervening annular space F between the shoulderJ and the flange E of the inner section 0, in which case the 5 wear of the rotating traveler upon the spinning-ring will be received upon the outside of the section A and upon the under side of the flange E. The telescopic section 0,

whether placed outside or Within the section A, is preferably held in place by frictional contact and is provided with slits C in order to increase its elasticity.

The traveler G (shown as detached in Fig. 3

ripheral track.

consists of anintegral ring,preferably formed from a single piece of wire and provided on one side with a hook H, or in lieu thereof an eye, to engage the strand I of yarn. The wire is twisted together at H, below the hook H, and is bent in an annular form at H 11 with the ends of the wire twisted together, forming a projecting spur H of sufficient weight to act as a counterpoise to the weight of the hook H and twisted section 11, so that when the traveler is rotated at a high speed the centrifugal force of the hook H and twisted section H, which would tend to draw the opposite side of the annular traveler against the peripheral track ofthe spinning-ring, will be counterbalanced by the centrifugal force of the spur H The interior diameter of the annular traveler is somewhat larger than the diameter of the peripheral track about which it rotates, so that when a high speed is given to the annular traveler the counterbalanced centrifugal forces, due to the momentum of the hook H on one side and the spur H upon the opposite side, will cause the annular travelerG to rotate free from contact with the pe- When the annular traveler is rotated at a low speed and the centrifugal forces operating upon the traveler are at a minimum, the strain exerted by the yarnstrand I as it is wound upon the bobbin tends to draw the traveler G toward the center of the spinning-ring and carry the hooked side of the traveler into contact with the peripheral track of the ring, producing a friction between the spinning-ring and the traveler;

but as the traveler is placed upon the outside of the spinning-ring it is free to assume a position eccentric to the spinning-ring without being deflected from its circular shape, which is not the case when the traveler rotates upon a track upon the inside of the spinning-ring. G rotated upon a track on the inside of the spinning ring instead of the outside, the strain of the yarn exerted upon the hook at a low speed would carry the opposite side of the traveler against the spinning-ring, tending .to compress the ring into an oval shape and crowd itagainst the track.

I am aware that annular travelers have been employed with spinning-rings provided with an interior track; but such a construction produces an undue friction, owing to the deflection of the traveler from its true circular shape, requiring that the traveler be made unduly heavy in order to secure sufficient rigidity. By placing the track upon the outside or periphery of the ring and making the traveler larger in diameter than the diameter of the track I am able to rotate itat eithera high or a low speed without producing undue friction of the traveler upon the surface of the spinning-ring, and by properly counterbalancing the traveler I am enabled to attain an extremely high speed and rotate the traveler practically free from frictional contact with the ring.

If the annular traveler The traveler Gr is made from a piece of fine steel wire of about one-fiftieth of an inch ,in diameter or less, which is bent at its central section into the hook H and twisted together at H and H with the sides bent in a circular shape to inclose the peripheral track, with the diameter of the traveler greater than the diameter of the peripheral track, but less than the diameter of the flange E, and the traveler is readily inserted in the track or removed therefrom by withdrawing the section 0 of the spinning-ring from the section A.

I am aware that a spinning-ring has hitherto been made in telescopic sections, and I do not claim such broadly; but I deem it to be new to construct a ring in sections, each having a cylindrical telescoping portion with an exterior flange upon one section by which the ring is attached to the rail and an exterior flange upon the other section to prevent the removal of the traveler. Any of the ordinary ringholders may be used to secure the outer section A to the rail of the spinning-frame, or it may be conveniently attached by means of screws K,passing through slots K in the flange B, in order to allow the ring to be adjusted concentrically to the bobbin.

While I prefer a single hook II, more than one hook may be used, as shown at L L, Fig. 5, beneath which the yarn-strand can be car ried, as shown by the broken line M. The hook H is bent upwardly to carry it above the flange E. I
