A further object of the invention is to improve the character or mechanism of the particularly recited in the claims, the principal features of my invention being the rotatable detachable yarn spindle with ratchet disk, and the'detachable take-up and tension device. Y i

Connected with the pin 6 is a flangedisleeve 29 on which the spool or cop 5 with the usual cop tube 30 is mounted. This ro-.

tatable pin 6 is connected at its lower end with a ratchet disk 7, the disk being providedwith-notches or perforations 8 for j Instead of forming the tension 'device int'egrahwith: the base, the racer or foot is take-up stop-motion v slide '13 forced downwardb-y aspring 14 which has a bearing in ahead 15 fixed in the upper end of the tendevice. I Should the yarn break, run out orfunwind too fast, the stop-slide falls to the bottom of its slot where, as the carrier Ureacliesthe usual machine stop motion, it

comes in contact; with same and causes the machin to stop. The take-up slide is formed witha stop 17. 'In vthe fin is a thread-eye 16. jSecured to the tension device on one.

leasing devicecOnsists of'a collar 19, 'surround ng the tension deviceand formed at Thejouter end 23 of this lever is provided witha point or finger 24 adapted to engage a p with: the notches or perforations 8 in the 1 the tension device above the collar 19 and adapted to be adjusted by means of a vertically arranged split sleeve 26 which fric- J tionally engages with the tension tube and may be move up and down to regulate the pressure of'the spring 25. The head 1 5fis providedwitha yarn hook 26 and at one v so "side'the heaidihas a projecting arm 27 formed withi an open'eye 28. The'tension device is fixed" ingthefobt anda spool of yarn placed on the: yarnspindle. The yarn from the spool is slipped".under the hook 18, thence carried up over the yarn hook 265, down under the eyein the take-up fin 16, thence upward through theopen eye 28. .As draft is made upon the yarnthe take-up slide 13 is raised until the fin 16 engages with the, collar 19; then a continued upward move-' ment lifts the collar 19 raisingthefllever'21 and lifting the point 24 out of engagement with the notches 8, thus releasing the spool.

As soon as the spool is releasedthe tension on the yarn is slackened and the take-up slide moves downward under the action of the spring 14:. As soon as .it startsd-ownward the fin 16 moves out of engagement wlthv the collar 19., allowing the collar to drop and the lever to then engage the disk, and this movement is so rapid that the disk'will only move the distance fromnone notchito another, or from one perforation to another;

By providing the guide hook '18at about midway the height of the spool and then passing the yarn upward over the yarn hook 26 before engaging with the take-up slide,

' the slide can have greater movement'because i it oan go above the hook l8-and thus avoid 40 the common difficulty of breaking the yarn, thedraft on the yarn being-vertical, and also .allow' more length of thread between guide hook 18 and take-up and stop-motion slide l3 so that if for any reason should the lever 21 skip two or three perforations in .the ratchet disk 7, the take-up and stopmotion slide 13 would still not drop far enough.to unnecessarily stop the machine,-

--which is the case with carriers where the stop weight cannot rise higher than the cen I ter of the spool or tube. With my'device there is no wear on the spool .as it is rigid on the rotatable spindle, all wear coming on the spindle instead ofthe spool. Once suppliedwith the proper amount of spools they I will last a life-time. .In case a foot breaks or wears'out, it isonly necessaryto release the screw 11 and detachthe tension device, 'unscrew the pin 6 from the ratchet disk 7, remove the old foot and replace it with a new one and couple the'tension device and spool spindle to'the, new foot. The'expensive p'art'of the device is thetension mechanism and detachable spool spindle, which parts are preserved for use with any number of feet I claim-i l.
