METHOD OF SPINNING YARN.

Specification of Letter: latent.

Patented Apr. 29, 1 913.

Application filed July 95, 1918. Serial No. 711,414.

To all whom, it may concern:

Be it known that I, RANDOLPH CRoMr'roN,

IiiUnited States Patent No. 914,703 granted to me March 9, 1909 I show a shuttle e ui ped with means to sever the yarn drawn 0% fiom the filling carrier when a reversal in the direction of winding of the yarn is reached. The filling carrier wound for use in connection with such a-shuttle has a few winds laid thereon in one. direction sufficient for one or more picks of the shuttle,

across the lay, and the remaining winds of filling on the filling carrier were wound in a reverse direction. The mechanism shown and described in my patent operates in the loom with great accurac and with entire satisfaction, but the practical objection to its extended use has been due tothe fact that after the yarn has been spun upon a set of filling carriers in usual manncr it must be ro-wound upon a second set of filling carriers by means of a winding machine, in which the filling carriers are rotated first in one direction and then in the reverse direction. Heretofore it has not been possible to spin the yarn directly upon the yarn carrier with two windings in reverse directions, because the reversal of the winding reversed the twist in the am and thereby weakened and caused breakage of the yarn. In my efforts to overcome the objections hereinbefore noted I have discovered that b a simple manipulation of the filling carruns or bobbins in the spinning frame after the initial or primary winding of yarn is spun I can proceed with the spinning of t e secondary or final winding, in a reverse direction, and without any xalteration for variation in the twist of the yarn. By my present invention I am thus able to spin the yarn directly upon the filling carriers with two windings in reverse directions but with the same twist, so that the yarn is of uniform strength throughout. I am also able, by my present invention, to spin the yarn on any usual or well known form of ring spinning frame.

The novel features of my invention will be described in the subjoined specification and articular-1y pointed out in the following 0 aims.

igure 1 is a view of a suflicient portion of a usual ring spinning frame showing the filling carriers ositioned for the winding thereu on of tlie initial winding of the yarn: ig. 2 is a similar view, but showing the filling carriers inverted and in readiness for the secondary or final winding of the yarn thereupon, but before the rail is dopressed. Fig. 3 is an enlarged view in elevation of a filling carrier with the two windin s of yarn thereupon.

eferring to Figs. 1 and 2, 1 indicates a spindle rai, 2 the vertically reciprocating rm -rail, 3 rings mounted on the ring-rail an having avelers 4, through whici the yarn 6 is on from the usual drawing rolls (not shown) to the filling carrier or bobbin, and at 6.1 have shown rotating spindles mounted on the rail 1 and provided with suitable whirls 7, all of well known'or usual construction in ring spinning frames.

In accordance with my present invention I place the filling carriers or bobbins 8 on the spindles with their butt ends uppermost, and the frame is started, with the ring-rail in proper position to lay a primary or initial winding 0, Fig. 1, of yarn upon the filling carrier at the desired distance from the butt end thereof. A suitable amount of yarn is so wound, sufficient for one or more picks of the shuttle across the lay, and then the frame is stopped. I now dotf the frame, removing the artly wound filling carriers from the spint les, and I invert or turn the filling carriers end for end, and replace them upon the spindles with their tips uppermost, as is usual, see Fig. 2. The frame is now started up and the spinning opera.- tion is resumed, and a secondary or final winding 10 of yarn is laid upon the filling carriers until they are properly filled, as shown in Fig. 3, whereupon the oieration is completed and the frame is doil'ed, the filling carriers then being ready to be used in the loom. It will be observed that no change is made in the direction of rotation of the fillin carriers by my method nor is there any a teration in the relationship between the various parts of the spinning frame as the yarn is delivered. It is customary to wind yarn with the ri ht hand wind, and it is so laid upon the fil ling carrier 8 when the primary winding 9 is spun thereupon, but when said filling carrier is removed from the spindle and inverted it will be obvious that the yarn will have the left hand wind when drawn oil in the loom shuttle. The secondary winding 10 is laid with the right hand wind and it so remains, but the inversion of the filling carrier between the initial 'am final windings causes said windings to be laid with the wind in reverse directions, as will be apparent. nasinuch, however, as there is no chan e in the direction of rotation of the spind e or in the lead of the yarn from the ring to the fillin carrier there is no change or variation in the twist, either as to its direction or amount, and in consequence the twist of the yarn is the same, and uniform,'from the beginning to the end of the operation of spinnin 'lhe time requisite to dofi and invert the filling eariers after the primary winding has been laid is short,.the doiling is easily accomplished, and if performed with reasonable care no ends will be broken as all that is necessary is to provide enough slack yarn for the proper inversion of the filling carrier. 1

By the process hereinbefore-set forth 1 get a filling carrier having two windings of yarn thereupon with the winds in reverse directions and with the same twist throughout the winding, and without requiring any change in the structure-of the usual ring spinning frame, the filling carrier spun in accordance with my invention being at once ready for use in the loom shuttle in accordance with the disclosures in my patent hereinbefore referred to.

Copies of this patent mav be obtained for Havin fully described my invention, what I c aim as new and desire to secure by Letters Patent is:

1.. The herein described method of laying arn upon a filling carrier, which consists in spinning a desired quantity of yarn upon the filling carrier, arresting the s innin and turnin the filling carrier end or en and resuming the spinning to com lete the laying of yarn upon the inverted fil ing carrier, whereby the two windin s are spun with the same twist but with t e winds in opposite directions.

2. The herein described method of spinning arn upon a fillin carrier, which consists in rotating the filling carrier and spinning a desired quantity of yarn thereupon, stoiping the rotation of the filling carrier an turning it end for end, resuming the rotation of the filling carrier in the original direction, and completing the spinning o the yarn thereupon, whereby the primary and secondary windings will be laid in opposite directions but with the same twist throughout.

3. The herein described method of spinning yarn upon a filling carrier, which consists in placing the filling carrier on .a spindle, rotating t m latter, and laying a desired volume of yarn, with a predetermined t wist, upon the ii ling carrier, stopping the spindle and inverting the filling carrier thereon, resuming the rotation of the spindle and the inverted filling carrier, and laying a second volume of yarn upon the filling carrier with the original twist, the inversion of the filling carrier causing the two volumes of yarn to be wound thereupon in o posite directions.

"In testimony whereof, l have signed my name to this specification, in the presence oi two subscribing witnesses.
