' '3 laims. (dim-42s view toward dispensing with the intermediate spooling "step in the usual prevalent methods of pabkagiiigyarns in preparation for weaving or knitting processes. This objective is realized in practice, as hereinafter more fully disclosed, through provision of a simple dispensing means including a holder by which the yarn skein is stationarily maintained in expanded condition and the yarn is so controlled as to be evenly withdrawn from the skein under the pull induced, incident to being wound upon the rotating cop, without danger of becoming snarled or tangled en route to the latter.

Another object of our invention is to provide a simple retractable support by which the skein holder is normally sustained in operative position in the winding machine, and from which said holder can be easily and quickly removed for application of the skeins thereto.

Other objects and attendant advantages will appear from the following detailed description of the attached drawings, wherein:

Fig. l is a fragmentary view in front elevation of a cop winding machine with a skein yarn dispensing means conveniently embodying our invention.

Fig. 2 is a fragmentary view of the skein holder and its support, likewise in front elevation, with a portion of the holder broken away and shown in axial section.

Fig. 3 is a view in elevation looking as indicated by the arrows III-III in F ig. 2.

Fig. 4 shows the skein holder itself in side elevation unloaded.

Fig. 5 is a perspective view showing the skein holder partly in elevation and partly in axial section; and

Fig. 6 is a fragmentary view in perspective of the holder support.

The winding machine illustrated in Fig. l is generally of Well known construction, the same having a frame 9 with legs whereof one is designated 10, a rotated spindle 11 at the top of the frame for the cop C onto which the yarn Y is wound, a tensioning means 12 through which the yarn passes enroute to the cop, and a Weighted follower arm 13, the latter being pivoted at 14 and carrying the traverse 15 whereby the yarn is distributed as it is wound onto the cop.

The yarn dispensing means with which the present invention is directly concerned is comprehensively designated 16, and, as shown, comprises a skein holder whereof the member 17 is fashioned to shallow conical cross sectional configuration from suitably stilt smooth-surfaced rigid sheet material which may be metal. At its periphery, the member 17 is formed with a rounded ring bead 18, and the edge of its relatively small central orifice 19 is similarly beaded as at 19a to ring form. For a purpose later on explained, member 17 is provided with a plu- 7 2,723,809 assented Nov. 15,1955

'rality-of button hole shaped apertures 20, which are equally spaced ,an'nularly about the central orifice 19. Secured within the hollow of. member ;17 by rivets21 are annularly-arranged inwardly-bowed semi-circular bracket straps, 22 whereto. are welded or otherwise permanently allixed in offset relation, two laterally spaced round sec- .tion concentric rings or annuli 23 and 24 to form asp'oollike. skein mounting. Continuously wrapped zig zag fashion circnmferentially about the. annuli 23 and 24 is a fiat elastic strand 25 0f rubber or the like.

The holder 16 .is sustained upright in the machine as shown in Fig. l, i e., with its axis horizontal, by a support in thef'orm of a lever 26 which is fulcrumed on a cross rod 27 extending between brackets such as the one indicated at .28 inpF-ig. ,l, on theframe legs 10 adjacent the'bottom ends of the latter. Atits distal end, lever 26 has, a lateral boss projection .29 with three equally-spaced radial arms 30 respectively provided, at their terminal ends, with headedstuds 31 corresponding to the similarly spaced annularly arranged button hole apertures 20 surrounding the central orifice of member 17. 1 Associated with each stud 31 is a slide washer 32 which is backed by a iieli cal compression spring 33. Lever 26 is normally held in upright position by a releasable latch hook pivoted at 36 to the upper end of a vertical arm 37 fixed upon rod 27. Upon lifting of latch hook 35, lever 26 can be swung outward in the direction of the arrow in Fig. 3 toward the observer in Fig. 1, to bring the holder 16 into the clear for convenience of loading, this outward swing being limited through engagement of a lateral lug 38 on the fulcrum boss 39 of said lever with the bottom of a lateral segmental recess 40 in a collar 41 secured to rod 27. Anchored on the boss of lever 26 is a pigtail guide eye 42.

Operation With the supporting lever 26 swung outward of the machine, as above explained and with the holder 16 in the clear, said holder is removed and a skein S of yarn is impaled over the annulus 23 and engaged upon the ring of crosswise segments of the rubber strand 28 between said annulus and the annulus 24. By the elasticity of the 6 segments of band 25, the skein is maintained in expanded condition as the yarn Y is drawn from the holder. In initially threading it, the end of the yarn Y is drawn from the skein over the ring bead 18 of member 17 thence inward and through the axial opening 19 in said member across the ring bead 19a of the latter, then outwardly from within said member, then through guide eye 42, then through the tensioning means 12 of the winding machine, then through the guide of traverse 15, and finally attached to the cop C. With this preparation, the holder 16 is swung upright to normal operative position in which it is shown in Fig. 1, whereupon the machine is started. By the pull induced through rotation of the cop C, the yarn is continually drawn from the supply skein S, its direction of movement being indicated by the arrow heads thereon. As the yarn is payed out, the loop thereof indicated at L in Figs. 1, 2 and 3 travels, i. e., gyrates about the peripheral bead edge 18 of member 17 as will be readilynnderstood from the drawings. The yarn is thereby definitely controlled and evenly dispensed from the holder. Due to the devious course followed by the yarn in passing about the large and small diameter annular beaded edges 18 and 19a of member 17, it is sub jected to a certain amount of tension which may be sufficient for the winding of certain types of yarn. In such instances, the use of the tensioning means 12 of the machine may be dispensed with and the yarn passed directly through the guide of the traverse 15 on its way to the cop.

Removal of the holder 16 is effected simply by first turning it slightly to bring the large ends of the button hole apertures into registry with the heads of the studs 31 on supporting arm 26, and then moved laterally clear ofis to keep the member 17 pressed against the headsof the screws 31 for firm support of the holder by the lever 26. The holder of our invention is not necessarily limited to use in connection with winding machines since, by suitable modifications within the scope of the appended claims, it can be adapted in other instances for use as a dispenser for maintenance of a supply from which the yarn can be withdrawn as and when needed. It is to be further understood that we do not consider ourselves" restricted to the precise details of construction herein shown and described by way of example, since these are capable of variation as will be readily understood without departing from the spirit of the invention.

Having thus described our invention, we claim:

1. A dispensing holder for skein yarn or the like, a hollow coned member fashioned from sheet metal having a smoothly-rounded peripheral edge bead, and a small central orifice with a smoothly-rounded circumferential edge bead; a coaxially-arranged spool-like member disposed in laterally-offset relation at the hollow side of the coned member, said spool-like member comprising a pair of laterally-spaced rings somewhat smaller in diameter A than the coned member and fashioned from stout wire, a .plurality of annularly-spaced inwardly bowed transverse bracket elements by WhiChrthfl two rings are rigidly connected and by which the spool-like member is secured to the coned member.

2. The invention according to claim 1, wherein a strand of rubber or the like is continuously wrapped zig-zag fashion back and forth about the two rings of the spoollike member as and for the purpose described.

3. The invention according to claim lywherein the coned member is provided with a plurality of annularlyarranged button hole-shaped apertures around its central orifice to correspond with similarly-arranged headed studs on a supporting bracket whereby upon registry of said apertures with said studs and subsequent partial turning of the holder, the latter is removably locked to the bracket.
