ament.

T 0 all whom it may concern: I 1

Be it known that I, CHARLES J. TARRANT, a citizen of the United States, residing at Central, in the county of Pickens and State of South Carolina,have invented certain new and useful improvements in Spinning- Rings and Ball-Bearing Travelers Therefor, of which the following is a specification, reference being had to the accompanying drawings. 7

This invention relates to spinning rings, and particularly to the travelers thereof.

In the spinning ring as ordinarily constructed, the traveler in its rotation on the ring wears the ring unevenly and the travelers have to be changed from two to three times a month and the rings, because of this uneven wear, last only from two to five years. Of course, uneven wear on the ring due to the operation of the traveler, impedes the smooth and easy action of the traveler and puts an undue drag on the yarn, and further this unevenness which the ring assumes, acts to wear the traveler itself, and because of the unevenness, the traveler wears the ring. Furthermore, and most ,importantly, the travelers as ordinarily constructed on spinning rings are very liable to fly oif- They may fly off in ten minutes time after they have been put on, or it may be a day before it flies off, but in every case wherever a traveler flies off, the machine must be stopped and a new traveler put on, thus wasting time. Furthermore, the ordinary traveler exerts a relatively hard pull or drag on the yarn and pulls harder when the traverse is at the lower end of its stroke than at the top of its stroke, thus giving an 7 This uneven tension is likely to break the yarn, and furthermore, with the present traveler dofhng must take place about every two and a half hours.

The general object of my invention is to improve the construction of the ring and traveler so as to secure a traveler which will not wear the ring unevenly, in which the traveler and the ring will last indefinitely because of the even wear, and even this wear is but very slight.

A further object is to provide a traveler which cannot fly off and which will exert an even tension on the-yarn at all t mes, whether the traveler and ring are oppo- Specifleation of Letters Patent. Patented Mar. 9, 192T Application filed. July 2, 1919. Seriallio. 308,124.

site the upper portion of the bobbin or opposlte the lower portion of the bobbin.

A further object is to provide a traveler and ring which, due to their construction.

will wind the yarn more firmly on the bob twisted and wound with my ring and traveler has a much less number of knots and tangles than yarn twisted and wound on bobbins by the usual spinning ring and traveler.

Other objects will gappear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure l is a transverse sectional view of a spinning ring constructed in accordance with my invention, showing it in its applied position;

Fig. 2 isa top plan view of the spinning ring;

Fig. 3 is a fragmentary vertical section enlarged to show the action of the traveler. My improved spinning ring and traveler are designed to be used precisely in the same manner as the ordinary ring and traveler, andll have, therefore, thought it unnecessary to illustrate the ring spinning frame and all its arts. The ring is traversed and the bob in rotated in the usual der 14 which then extends upward, as at 15,

this face with an inwardly extending shouland then is concavel curved upward, as at 16, the faces 13 an 16 meeting at a relatively acute angle; The ring 17 is formed with a base portion and has practically a uniform interior diameter 18 from the top to the bottom, but the outer face of the ring is reduced above the base portion, then extends upward to form the body of the ring, as at 19, and 'is formed with a relativel sharp-edged flange 20 at its upper en The depth of this ring 17 is such that the base portion 18. of the ring will rest upon the shoulder 14 of the holder, whilefthe flange 20 will project toward and be exactly opposite the sharp edge at the upper end of the shoulder. There is thus provided an annular chamber 21 between the ring and th holder with an annular slot leading from the upper end of this annular chamher. The traveler, as illustrated in Fig. 3,

consists of a piece of wire bent to form a straight. shank 22, which terminates in a head 23 at one end, the other end of the shank being bent to form alaterally disposed loop or eye 24. Loosely surrounding the straight shank and normally bearing against this head is a ball 25 which may be made. of hard steel or like material, and which has a diameter greater than the widtlrof the slot between the ring and the holder.

In the use of this device, the holder is, of course, disposed upon the usual ring supporting frame, which is vertically reciprocated by the traverse motion in the usual manner. The yarn (1 extends downward. as

usual, from the bobbins mounted on the spinning frame and passes through the eye 24 andthen extends to the bobbin 7). The bobbin 18, of course, rotated at a high speed and as a consequence the traveler travels around the ring 17 and acts to twist the yarn and wind it upon the bobbin in the usual manner of a spinning ring. The loop or eye-24 is always upward and inward and the eye 24 is always directed toward the bobbin. The ball 23 is so proportioned to the annular chamber 21 and the slot leading therefrom, that the ball will at all times ,ride against the side walls of the slot and project slightly upward through the slot. and the shank 22-will not, under these circumstances, come in contact with the side walls of the slot at any point.- The only part of the traveler which bears upon the ring and upon the holder is the ball 25, and

as this ball is freely rotated relative tothe shank 22, it will be obvious that it acts as an anti-friction element and permits the that the shank shall project upward -and v that it leans over toward and follows the bobbin as it moves up and down, thereby winding the yarn more firmly on the bobbin than-it is possible to do with the ordinary traveler and putsmore yards of yarn on a and that these are verygsimple and bobbinbefore'the bobbin has to be dotted.

This reduces waste and reduces all chance of tan led yarn. l urthermore, with my device, here is no need of inseparator, as the yarn will not balloon, as" it does with the,

ordinary spinning ring. Inasmuch as the yarn is wound more firmly upon the bobbin and more yarn can be placed u )on a single bobbin than is the case witht e ordinary spinning ring. it follows that the bobbins have to be dotted less treql-iently, thus reducing thenumber of dotier boys used. In actual practice I have found that by the use of my improved spinning ring, it is only necessary to doti' the bobbins once in every five hours, whereas with the ordinary spinning rings, it is necessary. to dofi' the bobbins every two and a half hours. Inasmuch as the niachincs have to be stopped while the bobbins a re being dofl'ed, it is obvious that there is asaving in not only the number of employees required to doii' the bobbins, but there is a saving in time, which amounts to a good deal in the course of a day. l urthermore, a very great saving is secured in the fact that thcse travelers cannot possibly fly off as the ordinary traveler.does, with the consequent stoppage and delays. Of course, as before explained, these rings.'conse('p1ent on there being no friction upon them, will last indefinitely. The ring may be easily disassembled from the holder in order to put in a new traveler whenevcr required.

In actual practice, it has been found that my traveler will not wear the ring, nor will the traveler be worn to any extent through long periods of time, so that thus a saving is accomplished in the number of travelers used, which is very great in large mills.

lam aware of the fact that a spinning ring has been devised whet-em a traveler 'is used haying-ashank provided with a rotatable ball, but the ring and traveler are so formed that there is more or less constant wear on the shank of the ring and on the wall of the slot, which would cause the rings to become uneven in a relatively short time.

With my device, the traveler is at all times pulled upward against the slot between the ring and the holder, and is not drawn laterally so far that the shank will bear against the side wall of the slot. Furthermore, my device is very readily assembled and disassembled and consists of but very few and simple parts, claim in a spinning ring, a holder and a ring cer coacting with the holder and formed to pic-ride an annular chamber, there being an annular slot extending from the horizontal face of the spinning ring into saidphamber, traveler comprising a shank exter in through the slot into said chamber and -aving an eye at its upper end, and an 'riction ball rotatably mounted on the inner end. oi? the shank and disposed in said chamber, said slot having'a width slightly less than the extreme diameter of the ball,

whereby the tension of the yarn passing through the eye will hold. the ball into contact wit l the upper wall of the chamber and projecting partially through the slot to thereby permit -l ree lateral oscillation of the ,111 spinning mechanism, the combination with a ring rail and a bobbin, of an annular ring holder mounted upon the rail, an annular ring disposed within the ring holder and resting thereon, therin and holder being cut out to form a circumferential chamber having a relatively wide, annular slot extending into said chamber from the upper face of the holder and ring, the walls of said slot being beveled, a shank extending downward into said chamber, and

the upper end of the shank being bent to form an eye, and a ball rotatably mounted upon the shank and disposed within the chamber, the slot having a diameter slightly less than the diameter of the ball, whereby the tension on the yarn passing through said eye will hold the ball against the upper wall of the chamber and projecting slightly through said slot to thereby permit the free lateral oscillation of the shank.

3. in a spinning ring comprising a holder formed to provide a cylindrical portion adapted to seat within a ring rail and having its inner face cut away to provide an annular shoulder and above the shoulder becut away to form one wall of an annular chamber and having an inwardly extending,

tapered flange at its upper end, a ring dis-- posed within the holder and formed to prov de a base portion resting upon the shoulder and cut away upon its outer face to form the inner wall of said chamber, the nner wall having an outwardly pro ecting, beveled flange at its upper end, the two flanges be the slot, whereby to permit the tension of the yarn passing through said eye to hold the ball in the upper portion of the chamber with a portion of the ball projecting through the slot to thereby permit the shank to have free lateral oscillation to a considerable degree.

4:. A spinning ring comprising a holder and a ring proper coacting with the holder and formed to provide an annular chamber and a relatively wide, annular slot leading into said chamber, and a traveler comprising a shank extending through theslot and less in diameter than the width of the slot, a retatably mounted anti-friction element carried on the inner end of said shank and disposed in said chamber, the outer end of the shank being bent to engage the aim, the anti-friction member having a wi .th transversely slightly less than the width of the slot and normally bearing against the walls of said slot and projecting partially there-- through, and the shank thereby having osto a considerable degree.

5. A, spinning ring having a circular race way on its upper face, the raceway having overhanging walls, a holder for the spinning ring, and a traveler moving in the circular raceway and beneath said overhanging walls, the traveler having an upwardly extending shank formed with an eye and being freely oscillatable between the overhanging walls through a relatively large arc in directions radial to the axis of the spinning ring and in the direction of the circular movement of the traveler.

in testimony whereof I hereunto and): my signature in the presence of two witnesses.
