INVENTOR. RALPH RAGAN ATTORNEY FIG 7 limited States Patent f SPINNING RING AND TRAVELER THEREFOR Ralph Ragan, Atlanta, Ga. Application October 12, 1954, Serial No. 461,782

3 Claims. (Cl. 57-120) My invention relates to rings for spinning and twisting yarn, and more particularly to an improved spinning ring and traveler therefor.

Heretofore, spinning rings have been machined, and the process was laborious and expensive; and the rings thus produced required separate holders for mounting them on the ring rails, and the oil sumps were provided in the holders.

An object of my invention is to provide a spinning and twisting ring stamped out of sheet metal whereby the ring may be very inexpensively made.

A further object of my invention is to provide such a ring incorporating novel lubricating means whereby adequate lubrication is provided without hazard of soiling the twisted yarn, and without the annoyance of accumulating lint and oil to impede the smooth operation of the traveler.

A further object of my invention is to provide a ring of the class described in which an oil sump is incorporated integrally into the ring, and for which no separate holder is required.

A further object of my invention is to provide an improved traveler.

A further object of my invention is to provide a spinning ring that offers the least possible resistance to operation, and which will be long lasting and wear evenly.

A further object of my invention is to provide a spin ning ring which will present a smooth outer surface to obviate the collection of flying lint thereon.

Other and further objects and advantages will be apparent from the following description taken in conjunction with the accompanying drawings in which like characters of reference designate corresponding parts throughout the several views, and wherein:

Fig. 1 is a vertical cross-sectional view of my spinning and twisting ring in operation.

Fig. 2 is a partial section on an enlarged scale showing an optional mounting for my ring.

Fig. 3 is a plan view of the cover plate of the device.

Fig. 4 is a top plan view of my spinning and twisting ring.

Fig. 5 is an enlarged broken cross-sectional view similar to Fig. 1 showing the oiling wicks and oil holes.

Fig. 6 is a fragmentary cross-sectional view taken along the line 6-6 in Fig. 3.

Fig. 7 is a fragmentary cross-sectional view showing an alternative means to supply oil to my ring.

Fig. 8 is a cross-sectional view taken along the line 88 in Fig. 7.

Fig. 9 is an elevational view of my improved traveler.

Referring now to the drawings more in detail, Fig. 1 shows my new stamped metal ring and improved traveler in a conventional setting wherein the traveler is mounted on the ring which is carried by the ring rail 10 for cooperation with the spindle 11 which rotates to build up a package of yarn on the bobbin 12, the yarn 13 being threaded through the traveler as will be well understood by those skilled in the art.

2,924,066 Patented Feb. 9, 1960 in a horizontal manner to form the supporting edge 18.

which may conveniently rest upon the ring rail 10. At

spaced intervals the supporting edge 18 is provided with slotted lugs 19, 19' for securely attaching the rings in place on the rail by means of the customary bolt means 24? generally provided for such purposes. As previously stated, the supporting edge 18 may rest directly on the ring rail 10; or, if desired, spacer blocks, such as the block 20 in Fig. 2, may be provided between the ring rail and the attaching lugs so as to space the twisting ring above the ring rail to provide clearance to facilitate cleaning and to prevent accumulation of loose fiber fly.

Oil holes 21, 21' are provided through the upstanding wall section of my twister ring for communication from the oil sump 17 to the inner wall periphery 15, and wick material 22, of ordinary construction, is provided in the oil sump 17 in sufiicient quantity to extend partially into the

holes

21, 21 to carry oil thereto but not so as to project through to the inner wall periphery 15 for a purpose hereinafter to be described.

A generally ring-shaped cover plate having a horizontal supporting edge 23 matching the supporting edge 18 and supporting lugs 24, 24- matching the

lugs

19, 19 is provided for covering the oil sump 17 and the wick material 22 therein. Near the central opening in its center, the cover plate tapers slightly upwardly at 23 and fits snugly about the outside of the upstanding body portion of my ring in a manner to seal the oil sump from fiber fly and dust. While the cover plate will be held snugly in place by means of the bolts 20, it may also be gued, or other wise afiixed, to the horizontal supporting portion IS of my stamped metal ring.

In order to supply oil to the oil sump, the cover plate is provided with an oil projection which rises above the level of the supporting rim 23 and then turns inwardly and downwardly to provide a small circular oil pit which terminates in a central opening 25 for the easy application of the spout of an oil can (not shown), and any oil remaining on top of the projection will drain through the opening 25 into the oil sump 17. It will be noted that the holes 21, 21' are provided through the upstanding wall section of the ring in such position that the opening 25 is between them so that oil from the opening 25 can reach both of the holes 21, 21' by going around the oil sump 17 in either direction, and the wick material 22 may be raised slightly off of the bottom of the oil sump 17, as shown in Fig. 5, for the free passage of oil therebeneath.

If use of the oil sump 17 is not desired, and sometimes be placed between the cover plate edge 23 and the supporting edge of the ring so as to project partially into one of the holes 21, 21', as best seen in Fig. 7, in which case the cover plate 23 would be pressed about the tube 26, as shown in Fig. 8, to form a tight seal and hold the tube 26 securely in place, the outer end of the tube 26 being attached to the one-shot lubrication system tubing indicated at 27. The traveler for use with my stamped metal ring is shown in Figs. 1, 5 and 9, and while conventional travelers may be used, I have provided an improved traveler which afiords extremely smooth operation with but very little wear, thus assuring long and etficient life. This improved traveler has canted sidewise when in operation.

a shank 28 provided at its lower end with an outwardly extending hook-shaped portion 29 and provided at its upper end with an outwardly extending hook-shaped portion 30, the hook-shaped portion 29 being formed to fit about the smoothly curved bottom wall 16 .of my ring, and the hook 363 being formed to overhang the rounded upper edge of the vertical wall portion 14 of my ring. The shank 28 has an upper end portion 28 which is bent inwardly to form clearance between the traveler and the ring for the passage of the yarn 13. In addition, according to my invention, my traveler also has this upper portion of the shank bent sidewise, as shown in Fig. 9, to counteract the tendency of the traveler to be By bending or offsetting the upper portion of the traveler in the direction of travel, the canting of the traveler is minimized and the drag of the traveler on the ring is also minimized, thus assuring smooth operation and long life.

In operation, oil from the sump 17 is carried by the wick material 22 to the openings 21, 21' through the wall section of my stamped metal ring, but it will be observed that I do not permit the wick material to extend through the holes 21, 21' so as to come into contact with the shank 28 of the traveler. Instead, the wick material 22 terminates short of the inner opening of the holes 21, 21', and oil is sucked through these holes by the passage of the traveler shank 23 thereover in close proximity thereto, thus providing ample oiling for the entire interperiphery of my ring without the danger of feeding an excess of oil and without the deleterious elfect of burning the wick. As a matter of fact, the wick material in my ring lasts indefinitely and needs no replacement because it is not consumed in the use of my ring and the associated traveler.

My rings are completely formed by stamping all machining operations being obviated, and the cover plate is similarly formed by stamping; and while my ring is preferably stamped from sheet steel material, the cover plate may be stamped from aluminum or other like material of a thinner gauge.

It will be obvious to those skilled in the art that I have provided an extremely novel and highly advantageous spinning ring and traveler therefor, and that 4 many modifications and adaptations may be made in the embodiments shown and described without departing from the scope of my invention as defined in the appended claims.

I claim:

1. A spinning ring of stamped sheet metal comprising in combination a horizontal supporting flange, an annular channel portion formed integrally therewith, said channel portion having an inner wall extending upwardly and inwardly at an angle of approximately 10 from the vertical and terminating in a substantially vertical ring portion to form a conical raceway for a traveler, said inner wall having an aperture therethrough, means extending partially through said aperture for supplying lubricant therethrough, and a ring shaped cover plate fitted snugly about said wall and overlying said channel portion, said cover plate having a horizontal outer portion matching said horizontal supporting flange and being in sealing engagement with said flange throughout the radial width thereof;

2. The device of claim 1 in which the means extending partially through said aperture is a wick which also extends into said annular channel portion, said cover plate being provided with an upstanding projection having a central pit terminating in an opening communicating with said annular channel for supplying oil thereto.

3. The device of claim 1 in which the means extending partially through said aperture is a hollow tube which passes between said horizontal supporting flange and said horizontal outer portion of said cover plate.
