METHOD 01E HANDLING YARN AND MACHINE THEREFOR.

Application filed nil-gust 28, 1919. Serial No. 320,505.

To all whom it may concern:

Be it known that I, ARTHUR L. REMING- TON, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful In'iprovement in a Method of Handling Yarn and Machines Therefor, of which the following, together with the accompanying drawings, is a specification. a

My invention relates to a method of handling or preparing yarn and a machine for carrying out the same.

The object of my invention is to provide a new method of handling or preparing yarn by means of which the yarn may readily be dyed while it is on a spool. A further object of my invention is to provide a machine for carrying out my method.

In dyeing yarn which is to be wound on a spool, it has been found to be most desirable to be able to dye the yarn while it is on the spool, as this procedure saves much labor and insures that the yarn will not be disturbed after it has once been wound on thespool. To this end, it has been proposed to dye yarn on the spool by placing the spool in a tank filled with dyeandputting the tank under sufficient pressure to force the dye into the yarn. In order that the dye may properly percolate through the yarn on the spool, it is necessary that the yarn be wound comparatively loosely there-.

winding the yarn so that it may readily be dyed under pressure and at the same time be used on the spool.

By my invention, I propose to provide a novel method and'a machine for winding the yarn from a standard jack spool onto a dunt my spool, in sucha manner that it may be readily dyed under pressure, after which the yarn may be rew-ound on the standard jack spool.

, In the accompanying drawings, Figure 1 is aview in side elevation of a machine for carrying out my method.

Figure 2 is an end view of the machine shown in Fig. 1.

parts in the different figures.

Referring to the drawings, the machine comprises a frame 1 provided at oneend with bearings 2 for r'ota'tably supporting a jack-spool 3. A guide roll '1 is rotatably mounted at the other end of the frame 1 and is adapted to be driven from a suitable source of power by the pulleys 5 and abelt 6, as best shown in Fig. 2. A dummy roll 7 is rotatably supported between trunnion arms 8 that are pivotally mounted at one end on the upwardly extending projections 9 of the frame 1. The dummy spool 7 is thus adapted to rest upon the surface of the guide roll 4: with its end flanges 10 spanning the same.

The surface of the guide roll' 4 is provided with a plurality of V-shaped grooves 11, as best shown in Fig. 2, each groove passing entirely around the roll and at an oblique angle with the axis of the roll, the pitch of each groove being equal to the distance between the strands of yarn, and the number of grooves being equal to the number of strands, for a purpose to be hereinafter described. The particular form of the guide rolltforms no part of my present invention, but is substantially the same 'as the roll shown and described 111 Pat. No. 631,867 fora winding machine. The dummyspool 7 comprises a hollow cylindrical shell 12 that is provided with a plurality .o'fperforations 13, for a purpose to be herek inafter described. 1

on, and difficulties have been encountered in The pressure between the dummy spool 7 and the guide roll-4 is adapted to be adjusted by means of a; plurality of weights 14-, that are mounted in side by side relation upon a shaft 15 carried between the legs 16 of the frame 1. The shaft 15 is connected to the pivoted trunnion arms 8 by means of links 17 and 18, so that turning of the shaft 15 under the influence of the weights 14 will cause the trunnion arms 8 to be moved about their pivots with respect to the guide roll 1 and thereby regulate the pressure between the guide roll 1 and the dummy spool 7 The weights 1 1 are loose on the shaft 15 and are adapted to be fixed atany given position i i p I thereon by means of set screws 19. A brake Like reference characters refer to like arm 20 provided at one end with abrake shoe 21 adapted to engage the yarn on the jack spool 3, is mounted on a shaft 22 rotatably supported between the legs 23 of the frame 1. The shaft 22 is provided with weights 24 for causing the brake shoe 21 to engage the yarn on the jack spool 3 with a pressure which may be varied in the same manner as with the weights 14-. A handle 25 is also mounted on the shaft 22 for the purpose of quickly releasing the brake shoe 21.

Having thus described the various parts of my machine the operation thereof in carrying out my method. is as follows z-The jack-spool 3 is first wound with the yarn to be dyed, after which the spool is placed between the bearings 2 and the brake arm 20, so adjusted by means of the weights 2% that the brake shoe 21 will exert an appreciable pressure upon the jack spool winding. The empty dummy spool 7 is then placed between the trunnion arms 8 and the weights 1-1 are so adjusted on the shaft 15 as to cause a slight pressure between the dummy spool 7 and the guide roll 4. The yarn 2G is then led from the jack spool 3 over the roller 27 to the dummy spool 7, after the strands thereof have been placed in the grooves 11 of the guide roll 4. The guide roll l is then driven, which in turn drives the dummy spool T and causes the yarn to be Wound thereon. As the yarn is being wound, the grooves 11 cause a traversing movement of each individual strand, thereby preventing a given strand from occupying the same position on the dummy spool 7 during two successive revolutions of the spool 7. As the dummy spool 7 engages the guide roll l with only a slight pressure the resulting winding upon the spool 7 will be comparatively loose and considerably larger in diameter than the original winting that was upon the iaclr spool 23. Furthern'iore, the traversing movement of the individual strands of the winding results in a winding upon the spool F that is more or less open. After the yarn has been transferred from the jack spool 3 to the dummy spool 7, the spool 7 is removed from the machine and is placed in the pressure dyeing tanlr. The perforations 13 permit the dye to percolate through the yarn quite easily.

After the yarn on the spool 7 has bee dyed and allowed to dry, it is ready to be rewound. The empty jack soool 3 is then placed between the trunnion arms 8 and the dummy spool '7, with the yarn thereon, is placed between the bearings 2, thereby reversing the former positions of the spools. The weights 14: are then set so that inaxi mum pressure will be exerted. between the jack spool 3 and the guide roll l, as indicated in dotted lines. The PTPSSHTG exerted by the brake shoe 21 upon the winding of the dummy spool 7 is also increased. The yarn is then rewound upon the jack spool 3 in the same manner as previously t escribed. and as the pressure under which the yarn is wound is greatly increased, it is obvious that the winding will be much tighter and will be substantially the same diameter as the original winding upon the incl: spool 0. The jack spool 3 with the dyed yarn wound tightly thereon is then ren'ioved from the machine for further use.

From the foregoing it is apparent that the use of my method and of my chine, it is possible to wind yarn fro; standard jack spool upon a dummy in such a manner that it may be readily dyed by the pressure method. In addition, by my machine, it is possible to rewind the yarn, after it has been dyed, upon the ori inal jacl: spool, in such a manner that it will have the same com )actncss as the original winding.

l Vhile l have shown my method as being carried out by a specific type of machine, it is obvious that it is not so limited, but may as well be carried out by different machines which may be designed to carry out the same method. I desire therefore that only such limitations be imposed thereupon as may come within the scope of the appended claims.

I claim,

1. A method of preparing yarn which consists in first winding yarn upon a jack spool, then loosely rowinding the yarn upon a dummy spool with superimposed layers of yarn crossing each other, then dyeing the yarn on the dumn'iy spool and finally in. rewinding the yarn compactly upon the jack spool.
