SPINNING RING AND TRAVELER Harvey E. Herr, Buffalo, N. Y., assignorto Herr Manufacturing Company, Inc., Buffalo, N. Y., a corporation of New York Application December 3, 1945, Serial No. 632,319

4 Claims. (01. 57-120) This invention relates to certain new and useful improvements in spinning rings and travelers employed in connection with spinning machines.

It has for one of its objects to so design and construct the ring and the traveler wherein the bearing faces of the ring are so disposed as to provide for an upward and outward thrust or pressure of the traveler against the ring at all times to counteract or eliminate any tendency of the traveler to jump up and down on the ring during the spinning operation and accordingly insure a smooth running traveler and uniform thread tension.

Another object of the invention is to provide a ring and traveler construction of this character wherein the traveler is so designed as to provide maximum thread room between it and the ring and wherein the weight of the traveler is so distributed as to obtain proper balance.

A further object is to provide the ring with improved self-contained means for feeding at all times a constant flow of lubricant to the inner bearing face of the ring to efiect maximum lubrication with a minimum of oil consumption.

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 accompanying drawings:

Figure 1 is a top plan view of the improved ring and traveler in place on the ring-holder. Figure 2 is an enlarged sectional side elevation thereof. Figure 3 isan enlarged side view of a modified -form of the traveler. Figure 4 is a section side elevation similar to Figure 2, but showing a modified form of the invention. Figure 5 is an enlarged side view of the traveler employed in such modification.

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

Referring to the form of my invention shown in Figures 1-3, inclusive, i0 indicates the holder which is adapted to, be mounted on the traverse bar of a spinning machine, and H indicates the spinning ring which is detachably applied to the holder and upon which the traveler I2 revolves. The holder may be ring-like in form with its opening i3 adapted to receive the lower portion of the spinning ring in a snug flt, and it has slotted attaching flanges projecting outwardly therefrom for vdetachably securing the holder to the traverse bar. Formed integrally with the holder at one side thereof is a lubricant-receiving well It.

The upper or traveler-engaging portion of the ring is preferably of the cross section shown in Figure 2, wherein the top and bottom faces I! and l5, respectively, are substantially parallel to each other in horizontal planes with the bottom face in approximately the same plane as the top side of the holder or at right angles to the axis of the ring. The inner bearing face I! of the ring is straight and oblique to the horizontal, being flared upwardly and outwardly or of inverted frusto-conical shape, while the outer portion l8 thereof may be substantially V-shaped, as shown, to provide an outwardly-flaring rim IS. The top side of the ring is substantially flat.

The traveler i2 is made from a single piece of wire and is of substantially V-shape, as shown in Figure 3, including a bearing leg 20 for straightwise engagement with the inner bearing face I! of the ring and terminating at its free or lowerend in an outwardly-bent lug or foot 2i-for hooklike engagement with the bottom face I 6 of the ring, and a complementary symmetrically and angularly-disposed leg 22 which, during the operation of the traveler, clears the top face i5 of the ring and jointly with the leg 20 provides a threadengaging loop spanning the top side of the ring and with the vertex thereof positioned outwardly of the bearing face l'l. At its free or outer end the leg 22 terminates in an inwardly-bent lug or foot 23 in correlation to the rim l9 of the ring and in opposing relation to the companion foot 2i. In the operative running position of the traveler on the ring shown in Figure 2, it will be observed that the bearing leg 20 and its foot 2| snugly engage the corresponding bearing faces l1 and I6 of the ring to provide a true, uniform and steady guiding path for the traveler with the outwardly-fiaring contour of the bearing face i! exerting a constant upward and outward action or thrust on the traveler, resulting in an even and constant thread-tension and preventing any tendency of the traveler to jump up and down on the ring.

During this action, the traveler leg 22 and its foot the traveler. In applying the traveler to the ring 7 it is sprung over the same in an obvious manner.

For the purpose of effectually lubricating the bearing face ll of the ring, I preferably provide the lower portion of the ring I l contained within the holder ill with an annular lubricant-receiving channel 24 which communicates with the lower end of the well It through a duct 20 formed in such holder. Leading upwardly from this ringchannel 20 and intersecting the bearing face ll of the 'ring approximately midway thereof are one or more discharge ports 20 each containing a wick 21 extending into the channel and of the proper density for regulating the feed of the inbricant'to the bearing face.

If desired, as shown in Figure 3, the leg 22- of the traveler may be arched upwardly, instead of being straight, to thereby provide more space for the travel of the thread. a

In the modified form of the invention'shown in Figures 4 and 5, the upper portion of the spinning ring is of a cross section to provide an inner bearing face 20 which is straightand oblique to the horizontal and is flared upwardly and outwardly, while its lower bearing face 29 is horizontal and its top side or face 30 slopes inwardly toward the ring-axis. At its upper end the ring terminates -in an outwardly-extending rim II. The traveler 32 is substantially of the same shape as that shown in the previously-described construction, except that its vertex is more oblique and its upper leg is substantially at right angles to the ringwardly and outwardly from the inner edge of the lower bearing face in oblique fashion to the horizontal, and a traveler of substantially V-shape mounted onsaid ring and having the legs thereof terminating in oppositely-bent feet, one of the traveler legs and its foot, during the operation of the traveler, engaging flatwise and coextensively along the inner and lower bearing faces of thering, respectively, in contiguous fashion, and the complementary traveler-leg and its foot being clear of the top portion of the ring and with the vertex of the traveler positioned outwardly of said inner bearing face.

2. A device of the character described, comprising a spinning ring having a lower bearing face at substantially right angles to the ringaxis and an inner bearing face extending upwardly and outwardly from the inner edge of the lower bearing face in oblique fashion to the horily of said inner bearing face during the operation of the traveler, one of said legs straightwise engaging said inner ring-bearing face and terminating at its free end in a horizontally-extending foot engaging said lower bearing face,

iii

and the complementary leg clearing the top side of the ring and terminating at its free end in a foot in opposing relation to the foot of the other leg. 4

3. A spinning ring for a traveler. comprising a ring-body having a lower bearing face disposed at substantially right angles to the ring-axis and an inner bearing .face extending upwardly and outwardly from the lower edge of said lower bearing face in oblique fashion to the horizontal.

4. A device of the character described, comprising a spinning ring having an upper face. a lower bearing face and an inner bearing face,

the latter extending upwardly and outwardly,

from the inner edge of the lower bearing face to the companion edge of the upper face in oblique fashion to the horizontal, and a traveler for said ring having angularly-di'sposed legs defining a thread-engaging loop at the vertex thereof disposed outwardly of said inner bearing face during the operation of the traveler, one of said legs engaging flatwise and ooextensively along the inner face of the ring and terminating at its lower end in an outwardly-facing and acutelybent foot engaging the lower bearing face of the ring.
