Claims.

This invention relates to yarn package supports, and is concerned more specifically with supports designed for axially hollow yarn packages useful in connection with creels from which multiple yarns are drawn, as in warp beaming operations and the like.

The aim of my invention is to provide a support for the stated purpose which is of simple and inexpensive construction; to which the yarn packages can be easily and quickly applied and from which they can be as readily removed; which will permit quick change over from packages of coned configuration to packages of cylindric configuration without requiring special adapters as was ordinarily the case heretofore; and which will permit complete rotations of the package in taking up the slack after the leading end of one package is tied by the creel attendant, to the trailing end of a package on an associated holder in the creel, for maintenance of a continuing supply of the yarn.

In the attached drawings, Fig. 1 is a fragmentary view, partly in longitudinal section, of a creel provided with one of my improved yarn package supports.

Fig. 2 is a transverse section taken as indicated by the angled arrows II-II in Fig. 1.

Fig. 3 is a view like Fig. 1, showing an axiallyhollow frusto-conical yarn package in place on the support.

Fig. 4 is another elevational view of the creel with two of my improved yarn package supports associated to provide a continuing supply of the yarn; and

Fig. 5 is a view, in turn like Fig. 3,showing the support arranged for the mounting of a cylindric yarn package.

Referring first more particularly to Figs. 1 and 2 of these illustrations, it will be observed that my improved yarn package support comprises an arm II! with a vertical axis fulcrum hub adapted to fit freely about a post I2 of the creel. At the bottom, the hub H has radial lugs 13 which normally engage radial V notches M in the top of a collar |5 fast on the post l2, so that the arm If! is releasably held in a definite position circumferentially of said post. Extending at a slight upward inclination to the horizontal from a boss I6 at the distal end of arm H1, is a round ended stem l1, and upstanding from said boss at right angles to said stem is a. projection l8 with forwardly projecting brush bristles l9 adjacent the top thereof.

Rotatable about the stem I! is a holder 20 which is adapted to receive and frictionally retain a frusto-conical yarn package P (Fig. 3) having an axially-hollow core 0. As shown, the holder 20 comprises a collar 2| which is bored to slide freely over the stem l, and from which radiate, at circumferential intervals, a plurality of longitudinally-elongate straight-sided friction loops 22. These loops 22 extend to substantially equal distances beyond opposite faces of the collar 2|, each being formed from a single length of stout spring wire with a coil,22a at one end for more effective resistance to easy flexure, and the terminals of the wire being aligned to meet centrally of the inner side portion of the loop within a longitudinal groove 23 at the periphery of said collar. For the purpose of securing the loops 22, the metal of the collar 2| is displaced inwardly from the opposite side walls of the grooves 23 as at 24 in Fig. 1, over the terminals of the wire,

Lodged within a straight-bottomed transverse slot 25 in collar 2| is a keeper latch 26 fashioned to hair pin configuration, see Fig. 2, likewise from spring wire. As shown, the arm 26a of the latch 26 is engaged, as at 21, with one end of the wire of one of the lo'ops 22 bridging the slot 25, while its other arm 26b normally rests in a circumferential groove 28 in the stem H, the free end of the latter arm being retroverted as at 260 so that it can be readily grasped and lifted, against spring action, from said groove when the holder 20 is to be removed. By virtue of the arrangement just described, the holder 20 is prevented from shifting axially from a definite location on the stem I.

In the use of the support, the yarn package P is forced over the holder 20 to the position shown in Fig. 2, incident to which the spring loops 22 yield to compression, and, as a consequence, thereafter frictionally hold the package in place with the bottom end thereof bearing against the brush IQ for restraint against free rotation as the yarn is drawn from it.

In practice, the supports of my invention are made as rights and lefts and intended for association in pairs as shown in Fig. 4, with the arms In and It) so positioned on the creel posts l2 and I2, that the axes of the stems l1, H are radial to a guide 30 through which the yarn is passed en route to the beam of the warper (not illustrated) with which the creel is employed. With this set up, the trailing end of the yarn Y of the package P is tied to the leading end of the yarn Y of the reserve package P. Upon exhaustion of the package P, it is replaced by a new package, and the leading end of the latter tied to the trailing end of the yarn of package P. In this way a continuing supply is maintained for beaming in a manner well known in the art. However, with my improved support, it is possible to turn the holder upon which the new package is placed, fully about the stem against the resistance imposed by the brush 19,

to take up the slack in the yarn after the leading end thereof has been tied to the't'railing end of the package from which the yarn is' being drawn at the time.

A further advantage of my improved support is the facility with which the holder 20 can be removed from the stem li upon retraction of the keeper latch 26, so that it may be used in supporting a cylindric yarn package'PZ a'sshown in Fig. 5, whereof the core C2 fits the'stem I1.

Due to rounding of the end of stern II, theholder can be easily replaced, incident to which the latch 26 will automatically seek its place Within the circumferential groove 28 in the stem.

I claim:

1. In a'support-for axially hollow'yarn packages; a mounting stem; and a package holder comprising a collar rotatively engaged on the stem, a plurality of straight sided radially-arranged elongate spring loops at'int'ervals circumferentially ofthe collar aligned in the direction ofthe-stem and extending in pp directions:

beyond'the collar to substantially equal extents;- said loops converging toward theouter end of the-stem and having the'capacity to yield to-compressionas the yarn package is slipped into place o've'rthe holder.

2; A yarn package support according toclaim l; in which each spring loop 'is' formed from a single length of wire'with the terminals thereofa nchored within a longitudinal groove in the periphery of the collar.

15 one arm ofsaid latch having its end engaged with th'e inneranchored side of one of the loops overlyingthe slot, and its other arm lying against thebottom of the slot While normally engaging a circumferential groove in the stem, and said other arm having its end projecting beyond the collar for convenience of manipulation in withdrawing said last mentioned arm from said groove-whenitis desired to remove the holder fromthe 'stem';
