7 Claims. (01. 118-59) This invention relates to improvements in the spinning art and particularly to the spinnin rings and bar travelers employed in connection with spinning machines.

One of its chief objects is to so design and construct the spinning ring and its bar traveler as to render the ring non-heat generating and to require no lubrication, and to assure a uniform and constant bearing of the traveler with the ring, as well as even tension on the thread.

Another object is the provision of a spinning ring for bar travelers whose body or bearing portion is constructed of a fiber composition or like non-metallic material, which enables the traveler to operate at high speed in an efllcient manner without lubrication, and which reduces wear of the traveler to a minimum.

A still further object of the invention is 'to provide a fiber composition spinning ring having novel retaining or holding means applied thereto for supporting it on the usual holder-base, and for protecting it against accidental breakage or injury.

In the accompanying drawing: Figure 1 is a top plan view partly in section, of a spinning ring embodying my invention. Figure 2 is an enlarged cross section thereof, taken on line 2-2, Figure 1. Figure 3 is a detached cross sectional view of the outer ring or collar of the retaining means. Figure 4 is a similar view of the fiber ring-body. Figure 5 is a similar view of the inner ring or collar of the retaining means.

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 to be twisted are delivered by feed rolls (not shown) to a take-up spool or bobbin 10 mounted on the usual revolving spindle. Traversing this bobbin is a vertically reciprocating bar 11, the spool extending through an opening 12 in the bar, as seen by dotted lines in Figure 2.

Mounted on the reciprocating bar 11 and surrounding the take-up spool 10 is the usual supporting base or holder 13 for the spinning or traverse ring upon which the bar traveler, indicated generally by the numeral 14, is adapted to revolve. During the operation of the spinning machine, the bar traveler assumes a more or less upright or outwardly directed position and revolves with and about the take-up spool, the thread passing under the traveler before being wound upon the spool and the bar 11 being reciprocated so that the threads are uniformly wound in layers upon the spool.

The holder 13 which supports the improved spinning ring may be stamped or otherwise formed from sheet metal, the same being in the form of a fiat, ring-like base having a neck 15 rising from its inner periphery and having yieldable clamping posts or brackets 16 rising from its outer periphery for detachably receiving andholding the spinning ring in place on the traverse bar 11. This holder is provided at its outer edge with the customary slotted ears 1'1 for securely fastening the same to the bar 11.

In its preferred form, the spinning ring for guiding the bar traveler about the take-up spool consists of an annular body 18 made of a fiber composition or like material, which is not subject to generating heat from the traveler riding over the same and which requires no lubrication. This ring body is shaped in the manner shown in Figure 2 and includes a substantially semi-circular inner peripheral bearing face merging into an outwardly and upwardly inclined bearing face 19 on its underside with which the traveler-arms are adapted to engage. Depending from its outer edge, the ring-body 18 has a rim or flange 20, and applied to such edge is a retaining or holding means for said fiber body preferably consisting of inner and outer rings or collars 21 and 22, respectively, which form a unitary structure with the fiber ring to not only protect it but to also enable it to be fitted to the holder base 13. The inner collar 21 terminates at its lower edge in an inwardly-facing flange or shoulder 23 which overhangs the lower edge of the depending rim 20 of the fiber ring and constitutes a stop for limiting downward displacement of the latter, the upper edge of this collar terminating short of the top face of the fiber ring. The outer retaining collar 22 is telescopically fitted over the companion inner collar 21 in clamping relation thereto and terminates at its upper edge in an inwardly facing flange 24 which overlies the adjoining top face of the fiber ring and not only forms a guard or protector therefor but prevents upward displacement of the ring relative thereto. The lower edge of this outer retaining collar extends below the companion inner collar and rests at its lower edge on the top side of the holder base 13 in the manner shown in Figure 2, affording sufllcient traveler-clearance between this base and the overhanging bearing face 19 of the fiber ring 18. The retaining collars are fitted to each other and to the fiber ring by a pressed fit, the whole producing a unitary structure which can be readily applied to and removed from gripping engagement with the bracket 16 ofthe holder base 13.

The traveler designed for use with this fiber spinning ring preferably has its cross bar 25 bent or deflected inwardly from its. opposite ends into substantially the form of a broad-shaped V, while the bearing arms 26 of the traveler project outwardly from the lower ended the between the inner periphery of the ring and the neck 15 of the holder base. By constructing the traveler in this manner, both arms 26 thereof have a uniform and constant bearing on the under-face 19 of the fiber ring, and the inwardly-bent cross bar 25 thereof properly guides the thread centrally of the traveler and assures balancing the same at all times, thereby affording a smooth and uninterrupted movement of the traveler about the ring and eliminating objectionable pounding of the traveler on the spinning ring. Furthermore, the provision of the fiber bearing ring renders lubrication unnecessary and assures the production of a uniformly clean product.

I claim:

1. In a device of the character described, the combination of a spinning ring having a fiber bearing face, and a bar traveler mounted on said ring and having depending legs terminating in outwardly deflected bearing arms engageable with said fiber bearing face and disposed obliquely to the plane of said legs.

2. In a device of the character described, the combination of a spinning ring having a fiber bearing face, and a bar traveler mounted on said ring and having thread-engaging cross bar bent intermediate its ends to form obtusely disposed portions directed inwardly from the inner periphery of said ring, said traveler having depending legs at the ends of its cross bar terminating in outwardly-facing bearing arms disposed at an obtuse angle to the adjoining cross bar portions.

3. A spinning ring, comprising a fiber body, and retaining means therefor including interengageable telescopically-fitted collars encircling said body, each of the collars having an inturned flange at one edge overlying the adjoining top and bottom sides of said body, respectively, the outermost collar having its unflanged edge extending below the flanged edge of the companion collar.

4. A spinning ring comprising a fiber body, and retaining means therefor including interengageable collars telescopically fitted one within the other, the inner collar encircling the periphery of said body and having an inturned flange at one edge constituting a shoulder for limiting axial displacement of the body relative thereto in one direction and the outer collar embracing the inner one and having an inturned flange at one edge constituting a shoulder for limiting axial displacement of the body in the opposite direction.

5. A spinning ring, comprising a fiber body having a bearing face on its underside and a depending rim encircling the same, a metallic collar fitted over the periphery of said body and having an inwardly-facing flange at its lower edge forming a stop shoulder against which the lower edge of said body-rim is adapted to bear, and a clamping collar encircling said flanged collar and having an inwardly-facing flange at its upper edge overlying the adjoining top face of the fiber body.

6. A device of the character described, comprising a substantially flat, ring-like base having a neck rising from its inner edge and brackets rising from the other edge thereof, and a spin ning ring for a bar traveler mounted on said base and consisting of a fiber body having retaining collars encircling the same in telescopic, clamped relation and each having an inwardly-facing flange at one edge overlapping the adjoining top and bottom sides of the body, respectively, to prevent axial displacement of the latter, the outer retaining collar extending below the ring-body and abutting at its lower edge on said supporting member, the periphery of said outer collar engaging the supporting member brackets.

7. A spinning ring, comprising a non-metallic, non-heat generating body having a substantially semi-circular inner peripheral bearing face merging into an outwardly and upwardly inclined bearing face on its underside for a bar traveler and a rim encircling the same, the metallic collars fitted over the periphery of said rim and each having an inturned flange at one edge forming a stop shoulder against which the corresponding top and bottom edges of said rim are adapted to bear.
