SPINNING RING AND TRAVELER THEREFOR- Application May 28, 1937, Serial No. 145,245

3 Claims.

This invention relates generally to certain new and useful improvements in the spinning art but more particularly to the spinning rings and bar travelers employed in connection with spinning machines.

One of its chief objects is to so design and construct the ring and traveler as to effectually control and guide the traveler in a true and uniform path to maintain an even and constant thread-tension, and to provide for a downward and outward thrust or pressure of the traveler against the ring to counteract any tendency of the thread to exert an upward pull or thrust on the traveler during the spinning operation.

Another object of the invention is to provide a ring and traveler construction whereby chattering of the traveler on the ring is eliminated and wear of the parts is reduced to a minimum.

* A still further object is to provide effective means for retaining the traveler in a suspended position on the ring and to so construct the traveler that it is open-ended and may be adjusted to any length to suit the tension desired.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanyingdrawing:- Figure l is a side elevation of the spinning ring and traveler embodying my invention, the same being shown associated with the traverse bar and bobbin. Figure 2 is a top plan view of the ring and traveler. Figure 3 is an enlarged central cross section of the ring and associated parts.

Figure 4 is a side view of the traveler depicted in the previous figures. Figure 5 is a fragmentary cross section showing a modified form of my invention. Figure 6 is a side view of the traveler depicted in Figure 5.

Similar characters of reference indicate corresponding parts throughout the several views.

In spinning machines of the character to which my invention is particularly applicable, the threads are delivered by feed rolls (not shown) to a take-up spool it and traversing the same is the usual vertically-reciprocating bar I l. Mounted on this'bar surrounding the take-up spool is a supporting member or holder l2 of substantially ring-like form and which is alined with an opening l3 formed in the bar. Applied to this holder is the spinning or traverse ring M upon which the traveler I5 is adapted to be-revolved.

Rising from the holder-body I2 is an annular flange I6 which is provided with an internal seat or shoulder H, the spinning ring I4 being fitted within this flange and resting at its bottom edge upon such shoulder in the manner shown in Figure 3. This spinning ring is detachably held within the holder by means of a clamping memher which may be in the form of a split ring l8 detachably fitted within the holder-flange It in bearing contact with the top side of the con-' tiguous portion of the ring.

The ring 14 and traveler l5 are preferably so designed as to have a tendency to impart a down 10 ward and outward movement of the traveler relative to the ring, whereby the pressure of the traveler on the ring is from the top down and from the inside out with the result that chattering'and undue wear of the parts is reduced to 5 a minimum and, further, any tendency of the thread to pull upwardly on the traveler during the spinning operations is effectually counteracted by the aforesaid relative disposition of the ring and traveler. To this end, the spinning ring 20 M is preferably of the cross section shown in Figure 3, wherein the inner bearing surface l9 thereof is flared downwardly and outwardly or frusto-conical in shape, while the top terminates I in a laterally ofiset orv inwardly-directed, an- 5 nular flange 20 having a substantially'flat bearing face 2i in a plane at right angles to the axis of the ring. The inner edge of the ring-flange may be beveled or flared outwardly, as indicated at 22. The traveler H5 is made from a single 30 piece of wire and is of substantially the shape shown in Figures 3 and 4, the same including an outwardly-inclined bearing leg 23 which bears against the companion inclined bearing wall 59 of the ring, anda horizontal bearing bar 24 which 35 bears upon the top face 2! of the ring, the inclined traveler leg being disposed at a more or less acute angle to the top bearing bar. The traveler leg 23 is straight and free of any projections or the like at its lowerend while the top bar 24 termi- 40 nates at its outer end in a downwardly and outwardly-bent lug 25 and at its inner end in a looplike portion 26 joined to the leg and which embraces the adjoining flanged portion of the spinning ring, the bar and loop constituting a retaining or suspension hook for the traveler and possessing sufiicient resiliency to be sprung over the ring-flange 20. As shown in Figure 3, the thread engages that portion or loop 26 of the trav- 50 eler formed at the junction of the traveler leg 23 and bar 24, and in the normal position of the traveler on the ring this thread-engaging portion of the traveler subtends the flared edge 22 of the ring-flange 20, thereby providing a clearance or 5 space between these parts for the unobstructed travel of the thread.

By this construction, the traveler bears firmly with its leg 23 and bar 24 against the companion inclined and horizontal bearing faces l9 and 2| of the ring, respectively, with the lower arm of its looped portion 26 hearing against the underside of the ring-flange 20, whereby to properly guide and prevent chattering of the traveler, as well as to retain the traveler on the ring particularly when starting up. Furthermore, during the spinning of the traveler about the ring, the pressure exerted thereon, due to centrifugal force, tends to urge the traveler downwardly and outwardly against the respective ring-bearing surfaces, and this resulting force on the traveler effectually counteracts any tendency of the thread to pull upwardly on the traveler.

In the modified form of ring and traveler shown in Figures and 6, the ring 21 is substantially the same as that previously described, with the exception that the top of the ring terminates in an outwardly-directed flange 28 and the traveler is shaped to provide the same downwardly and outwardly-inclined bearing leg 29 and bearing bar 30, with the latter, however,-shaped at its outer end, as indicated at 3|, to extend beneath the flange 28. At the junction between the leg 29 and the bar 30 is a thread-engaging loop 32. As with the previously described construction, this modified form of my invention performs those same results of creating a downward and outward thrust of the traveler to prevent chattering and provide an even bearing for the traveler at all times.

It will be noted that the bearing legs 23 and 29 of the respective travelers heretofore considered are straight ended, being free from retaining or hooking engagement with the respective rings. By this construction, the travelers may be made in varying lengths or their legs cut off to suit, whereby the travelers are readily adaptable to the thread tension desired under different working conditions. The longer the traveler-legs, the greater the increase in tension created, and the bottom of the ring is sufficiently clear of the holder l2 so that the traveler legs may extend below it in the manner shown in Figure 5.

In applying the travelers to the rings, they are merely snapped over the flanged tops of the rings in an obvious manner.

I claim as my invention:---

1. A device of the character described, comprising a supporting member through which a takeup spool is adapted to extend, a spinning ring for a bar traveler, said ring having a base portion mounted on said-member and a portion rising therefrom of substantially frusto-conical shape to provide an outwardly and downwardly sloping bearing face for the traveler, the top of said ring terminating in a laterally-offset annular flange, and a traveler mounted on said ring and having a bearing leg engageable with said ring-bearing face and terminating at its upper end in a bearing bar engageable with the top of said ringflange, said bar being joined with said leg by a loop portion disposed in the plane of said flange and spaced from the adjoining portion thereof to form a thread-receiving loop.
