TWISTER RING James Joseph Kloran, Cumberland, Md., assignor to Celanese Corporation of America, a corporation of Delaware Application April 11, 1944, Serial No. 530,498 6 Claims. (o 57-120) This invention relates to twister rings of the self lubricating type especially rings employed in the down twisting of yarn or thread. j

An object of the invention is the construction of a ring in which is threaded a lubricating wick, the ring being so constructed that the life of the wick is reatly lengthened thus resulting in v a saving in the number of wicks consumed and in the-man-hours required for inspection and changing of wicks. 1

Another object of the invention is the construction of a ring of the self-lubricating wick type in which the capillary flow of lubricant through the wick is at a maximum thus extending the life of the ring and of the traveler and easing the maintenance of the desired tension on the yarn.

A further object of the invention i the construction of a ring of the wick lubricating type in which the wick may be drawn tight into the wick groove where it is snugly held without choking off the flow of lubricant therethrough and in which the wick forms no sharp protrusions into the path of the flyer or traveler.

Other objects of the invention will appear from the following description-and drawing.

In the drawing wherein is shown one embodiment of my invention:

Fig. 1 is a plan view of a ring with wick inoperative position, and- Fig. 2 is a cross-sectional view taken on the line 2-2 of Fig. 1.

Like reference numerals indicate like parts in both views of the drawing.

Textile devices for winding and twisting yarn that employ a ring and traveler are very common. As an example of such a device there may be mentioned the down twister which pulls a yarn from a source of supply such as a spool, down through a guide and/or tensioning device, through a traveler adapted to ride. around a ring and then on to the take-up package. example is the spinning machine which feeds a roving of wool or cotton fibers through drafting and feed rolls then as the twist is being inserted in the drawn roving, the roving passes through suitable guides, then through a ilyer or traveler mounted to ride around a ring surrounding a take-up bobbin or other package and then on to the take-up package. Many other types of winding and twisting devices are in use that employ a ring and traveler, either as a single unit or multi units where the ring are mounted in rows on a ring rail. To alleviate the great task of keeping the surface of the rings upon which the Another traveler rides properly lubricated, a self-lubricating ring has been devised employing a wick that dips into a well of lubricant and is threaded or laced about the ring so that the traveler contacts therewith and wipes a film of lubricant over the working surface of th ring. This invention is applicable to all such winding and twisting devices and is'a self-lubricatin ring that is fool proof, long lasting and produces less breaks in the yarn or thread being treated than rings heretofore employed.

In accordance with my invention, I construct a self-lubricating ring of the wick typewherein the wick is threaded or laced through holes in the ring, which holes are drilled or otherwise formed at an angle to the radius of the ring, and wherein the wick is drawn snugly into a wick groove formed in the ring. Such a construction has the advantages of allowing the wick to be drawn tighter without interfering with the flow of lubricant there'through. This permits the wick to be securely held in the groove, without forming a sharp angle in the path of the traveler at the working or inner face of the ring and without choking the flow of lubricant.

Referring now to the drawing for a more complete description of the invention, reference numeral l indicates a self-lubricating ring having a working face formed by the top 2, an inner face 3 and a portion 4, and having a supporting shoulder 5 provided on its outer face by which the ring is mounted in a ring rail (not shown) or other traversing or supporting element. On the inner face 3 there is formed a wick groove 8 while in the shoulder 5 or elsewhere on the outer face there is formed a wick guide 1. the wick groove and guide being connected at intervals with holes 8 through which a wick 9 is laced. The holes 8 are bored or otherwise formed at an angle to a radial line of the ring so that the wick 9 is bent only to an obtuse angle shown at II and II on the drawing, when the wick 9 is in operative position thus causing the wick to liein a straighter line than in the rings heretofore known. The obtuse angle formed by the wick allows the lubricant to flow freely through the wick even when the wick is drawn quitetight. It also forms a slanting protrusion at H for contact with the traveler thus eliminating the possibility of the traveler from being stopped or thrown out of its desired path at these points. which actions were the cause of many broken yarns on priordevices. The slanting surface II also greatly extends the life of the wick by preventing the traveler from hitting the projecting bend with a chopping or cutting action.

In the preferred embodiment of my invention, I

the holes are so formed that the distance between holes where the wick 9 lies in the wick groove 6 is from /m to /2a of the inner circumference of the wick groove 6 while the number of places the wick 9 lies in the wick groove may vary from 4 to 10. In this preferred embodiment, the holes 8 are formed such that axial lines A and B 8 with the radial line D'will depend'somewhat on the construction of the ring I, its thickness, its shoulder shape, the number of holes, and also the position of the wick groove 6 and wick guide 1, It is not necessary that the wick guide I be on the shoulder it may be located above or below the shoulder depending upon'the shape of the ring and the method of attaching the ring to the ring rail or other supporting device. Of course, the ring may be of any suitable Weight, shape and diameter for the particular twisting device upon "which it is to be used and may be made of any suitable material which is usually highly tempered steel.
