6 Claims; (Cl. 57 120) This invention relates to certain new and use ful. improvements in the spinning rings and tra'-'-- elers employed in connection with spinning machines.

It has for one of its objects to so design and construct the ring and its traveler that a smooth and uniform thread tension is obtained at all times during the vertical reciprocation of the ring and traveler assembly relative to the bobbin.

Another object of the invention is to pro' ide a ring and traveler wherein the bearing faces of the ring are so disposed as to provide for a down.

ward and outward thrust or pressure of the tray eler against the ring to counteract any tendency of the thread to exert an upward pull on the traveler during the spinning operation and to correspondingly design the traveler that its weight is distributed uniformly at opposite sides of its thread-engaging portion to substantially assure a balancing of the traveler to obtain uniform thread-tension and eliminate chattering.

A still further object is to provide a ring and traveler construction whose respective bearing portions are so disposed as to bring the threadgaging portion of the traveler below the top edge of the ring.

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 drawing:

Figure 1 is a side elevation of the improved spinning ring and traveler, the'same being asso-.

ciated with a traverse bar and bobbin. Figure 2 is an enlarged top plan view of the spinning ring and traveler mounted in place upon the ringholder. Figure 3 is an enlarged cross section taken on line 3-3, Figure 2.

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

Referring now to the drawing, l0 indicates the take-up spool of a spinning machine and traversing the same for reciprocation axially thereof is the usual traverse bar H on which'is mounted a supporting member or holder l2 of substantially ring-like form and alined with an opening l3 formed in the bar. Removably applied to this holder is the spinning ring 14 upon which the traveler l5 revolves.

The holder I2 is substantially L-shaped in cross section, including a base flange l6 which is adapted to rest fiatwise on the traverse bar and has slotted attaching flanges li projecting outwardly therefrom for detachably securing the holder to such bar. The spinning ring is detachablyapplied to the holder, and as shown in Figure 3, has a horizontal flanged portion 18 adapted to rest at its marginal bottom side on the top edge of the upright flange of the holder. A clamping element which may be in the form of a split ring I9 is engageable' with the marginalv top side. of the ring-flange l8 and is detachably anchored ingrooves 20 formed in the inner faces of upstanding lugs 2| constituting a part of the holder. a

The main body or web portion of the spinning ring I is preferably of the cross section shown in Figure 3, wherein the lower bearing face 22 is flared downwardly and outwardly or frustoconical in shape while the upper bearing face, 23 thereof extends upwardly and outwardly at substantially right angles to the lower bearing face. As shown in Figure" 3, these bearing faces are relatively displaced in spaced horizontal relation with the upper edge of the lower bearing face 22 being disposed inwardly of the opposing lower edge of the upper bearing face 23. The horizontal space between the opposing upper and lower edges of these bearing faces isprovided with an inwardly-opening annular channel or groove 24.

constituting a lubricating channel in which a suitable wick 25 is arranged for efiecting the distribution of the lubricant about the ring to effectually lubricate the traveler during spinning operations. The outer faces of the web or bearing portion of the ring ll are spaced from the surrounding wall of-the holder l2 and the bottom edge of the ring is spaced above the holderfiange l6 and provide ample clearance for the operation of the traveler.

The traveler i5 is made of a single piece of wire including an upper bearing leg 28 and a lower bearing leg 21, substantially right angles to each other for hearing engagement with the corresponding upper and lower bearing faces of the ring. The bent portion or vertex 28 of the traveler assumes a position on the ring wherein it is disposed below the top edge of the latter and wherein such vertex sub- I By constructing the ring and traveler in the these legs being disposed at manner herein shown and described, the weight of the traveler is distributed evenly above and below its point of thread-contact and which point is below the top edge of the ring, thereby assuring a balancing of the traveler to'provide a uniform thread tension at all times and eliminat- "ing chattering.

I claim as my invention:

1. A device of the character described, comprising a spinning ring for a traveler having upper and lower bearing faces extending upwardly and outwardly and downwardly and outwardly, respectively, from a plane between the upper and lower edges of the ring, the upper bearing face being displaced upwardly and outwardly from the opposing upper end of the lower bearing face to provide a horizontal space between such faces, and a traveler mounted on said ring and having singularly-disposed portions engageable with said ring-bearing faces, respectively, the bearing legs at their point of junction subtending said horizontal space and forming therewith an opening'for the thread.

2. A device of the character described, comprising a spinning ring for a traveler having a lower bearing face disposed obliquely to the horizontal and extending outwardly and downwardly from a plane below the top edge of the ring, and an upper oppositely inclined bearing face disposed at substantially right angles to said lower bearing face and having its lower inner edge ofiset upwardly and outwardly from the opposing top edge of the lower bearing face.

3. A device of the character described, comprising a spinning ring for a traveler having a lower bearing face disposed obliquely to the horizontal and extending outwardly and downwardly from a plane below the top edge of the ring, and an upper bearing face displaced upwardly and outwardly from the. opposing upper end of the lower bearing face, the inner wall of the ring between said relatively displaced upper and lower bearing faces being provided with a lubricant channel.

4. A device of the character described, comprising a spinning ring for a traveler having a lower bearing face disposed obliquely to the horizontal and extending outwardly and downwardly from a plane below the top edge of the ring, and an upper bearing face displaced upwardly and outwardly from the opposing upper end of the lower bearing face, the inner wall of the ring between said relatively displaced upper and lower bearing faces being provided with a lubricant channel, and a traveler mounted on said ring and having bearing legs disposed in substantially the same relative angular relation as said bearing faces, the bearing legs at their point of junction subtending said lubricant channel and forming therebetween an opening for the thread. 5. The combination with a spinning ring for a traveler having a lower bearing face disposed obliquely to the horizontal and extending downwardly and outwardly from a point below the upper edge of the ring and having an upwardly and outwardly extending upper bearing face displaced horizontally above the upper edge of the lower bearing face to provide a space between the opposing edges of such faces, and a traveler adapted for application to the ring and having bearing legs disposed in substantially the same relative angular relation as said bearing faces with its vertex extending inwardly of and subtending the, space between the opposing upper and lower edges of said upper and lower bearing faces, respectively, to provide a thread-engaging opening disposed at all times below the top of the ring, said traveler during its spinning movement about the ring being centrifugally urged downwardly and outwardly along said oblique bearing face to counteract any tendency of the thread to exert an upward and inward pull on the traveler. J

v 6. A device of the character described, comprising a spinning ring for a traveler having a lower bearing face disposed obliquely to the horizontal and extending outwardly and downwardly from a plane below the top edge of the ring, and an upper oppositely-inclined bearing face disposed in spaced horizontal relation to said lower bearing face, the upper edge of the latter being disposed inwardly of the lower edge of the upper bearing face.
