It consists of an upright member 28 attached to the link by means of a screw 29. A movable arm 30 is attached to the upper end of the upright member by means of a screw 31. This arm is also provided with a yarn guide 32, preferably a porcelain eyelet somewhat smaller than eyelet 25. The two yarn guides may be placed in co-axial alignment, or thealignment may be altered depending upon the amount of tension to be placed on the unwinding yarn.

The specific cone gripping features of the invention will now be considered:

A hollow tapered core member 33 is mounted on spindle 12. It is threaded so that the core member may be moved up and down the spindle. Athreaded stud 34 extends through the shell of the core member so that the core may be securely locked to the spindle at a desired position. Referring more particularly to Fig. 5 it will be seen that the core member is provided with a plurality of longitudinal slots 35, 35', 35",

each of which is adapted to receive a cone grip- I ping finger '36. The core member is also provided with a circumferential slot 37, which is adapted to receive a coiled tension spring 38. Figs. 1, 2 and 3 show the gripping fingers 36, 36', 36" in position. In order to get a desired pivotal action, the cone gripping fingers are con-' structed as shown more particularly in Figs. 2, 3 and 4. They are elongated and narrow, the sides next to the core member being provided with a curved protruding shoulder 39. A depression 40 is provided at the juncture of the longitudinal slots 35 and the circumferential slot 37 in the core member to receive this protruding shoulder. The side of the cone gripping fingers opposite the protruding shoulder is provided with a transverse slot 41 adapted to register at least in part with the circumferential slot 37 in the core member. The cone gripping fingers are advantageously rounded at their upper ends 42 more readily to receive a cone.

'In operation thumb screw 20 is loosened, balloon link 1'7 is moved back out of the way, and the upper ends of the cone gripping fingers 36, 36', 36" are advantageously pushed toward the spindle 12 (see Fig. 2). The coned yarn 10 on its paper cone 11 is then moved in position over the spindle, and pushed downwardly over the cone gripping fingers. It is preferred that the cone be pushed down sufliciently far so that the coned yarn itself may rest on the base support 13. In case the cone is not then sufliciently gripped, the cone is elevated and the core member 33 is moved upwardly along the spindle and locked ina position adapted to give the required frictional resistance between the gripping fingers and the inside of the cone. It will of course be clear that if the core member is toohigh on the spindle to permit the positioning of the coned yarn on the base support 13, the core member should be moved toward the base of the spindle into a position best located to give optimum results. Due to the slanting direction of the cone gripping fingers in their normal position, the

' base of the cone may readily be pushed down over the fingers. Since the gripping fingers are pivotally mounted on the core member, they are promptly placed in face to face alignment with the inside of the cone.

I claim:

1. The improvement in a coned yarn support comprising a spindle, a core member, the spindle and core member being threaded so that the core member may be advanced on the spindle, said core member being exteriorly provided with a transverse slot and a plurality of spaced longitudinal slots, cone gripping fingers loosely mounted in said longitudinal slots, said fingers each being provided with a transverse slot which registers with the transverse slot in the core member, and a flexible ring mountable in said transverse slots to hold said cone gripping fingers in pivotal position.

2. The improvement in a coned yarn support according to claim 1, comprising a flexible ring of coiled spring wire to hold the cone gripping fingers in position.

3. In a coned yarn support, the improvement comprising a core member, said core member being exteriorly provided with a transverse slot and a plurality of spaced longitudinal slots, cone gripping fingers loosely mounted in said longitudinal slots, said fingers each being provided with a transverse slot which registers with the transverse slot in the core member, and a flexible member mountable in said transverse slots to hold the cone gripping fingers in pivotal position, said cone gripping fingers being provided with a cone contacting surface that extends substantially along their entire length to afford an optimum amount of frictional resistance between the gripping fingers and the inside of a cone.
