UNITED STATES PATENT OFFICE FREDERICK KLEIN, OF COLLEGE POINT, NEW YORK, ASSIGNOR TO SEEP-EASTWOOD CORPORATION, OF' IPAT ERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY Applicatlon filed March 27, 1981. Serial No. 525,801.

This invention relates to creelsfor supporting wound yarn packages from which yarns are drawn, as in the operation of'preparing a warp, and particularly to that class of creels in which there is provision for shifting any package from its normal yarn delivering position to a position convenient to the operator for substituting an exhausted package by a fresh one. One object of the invention is to construct the creel so as to accommodate as many packages in a given area as possible and yet allow the shifting of any package to the position for dofling and substituting a fresh one,with ample c earance for that purpose. Another object is to construct a creel so as to simplify thesame and reduce the cost of manufacture and of assembling its various parts and permit the ready placement of the elements of each unit involved in the delivery I of the yarn and its tensioning. or guidingmeans in different elevations on the frame or main supporting structure in any arrangement desired or required by the number of such units to be resent.

I attain my rst object by packages in groups of two and mounting each two packages on carriers which are pivotedon substantially parallel axes and, when the packages are in working or delivering position, lap (as cross) each other between their packages and their pivots..

I attain my second ob ect by constructing each yarn supply (which I here mean 'to include, with yarn tensioning or other guiding means, means to support the latter and also a yarn package with the axis of the latter substantially alined with said means) as a unitary structuregattached tothe frame, being preferably adapted to assume various posi-.

arranging the ply with the wound package shown in broken outline. g

1Fig. 3 is a rear elevation of two of the supp ies I Fig. 4 a plan thereof; 1

Figs. 5 and 6 a fragmentary plan'and rear elevation on a larger scale;

Figs. Z and'8 are a side elevation and plan showing ,wound packages .in the form of spools insteadof cones; and c Fig. 9 shows a modification. 4

Any suitable frame may be used. In the present example it is shown as including two upright converging rid-like structure's each i comprising a lower orizo'ntal rail 1, a top horizontal rail 2 and bars or uprights (as pipes or tubes) 3 rigidly connecting them, on y a fragment of one top rail appearing on Fig. 1. The ends of the structures ,may be connected by braces 4 (only the bottomone at the wider end of thecreel being shown) and atthe wider end of the creel there may be a reed 5 or equivalent means for keeping separated those yarns which lie all in the same horizontal plane.

Each yarn supply here includesv a bracket,

a wound package carrier -(in the preferred form two such carriers) mounted therein and atension (or guiding) means. It is attached to one of the uprights 3 as a unit and is capable of adjustment up or down thereon as such, as will appear.

The bracket includes a body part 6 and an arm 7 projecting rigidly and forwardly therefrom. The body part is adapted to bear against one of the uprights 3 and for this purpose it has a rear groove 8 to receive the same.- It forms one member'of a clamp the other member of which is a-U-shaped clip9 which embraces the upright andhas its ends threaded and pe'netratingthe' body part and provided with clamping nuts 10. At thetop it has an upstanding horizontal frontal ledge 11 to guide loose yarn ends and loops, the ends of w ich form upright rearwardlyfacing stops 11a, and at the top and back it has at each sidean upstanding lug 12, each lug being spaced from stop 11a by a notch 12a. It also has an open-top bearing hole 13 between end of the arm 7, and so that each may beswung back into convenient position for dofi'- v ing the package, and so that, further, the

equipment comprising the carriers and packages will occup the minimum of space and not interfere with each other when either is moved from or to either working or dofling position. Each carrier has a trunnion to enter a bearing hole 13 and a spindle portionto en: ter the axial hole of the package A. It is here a piece of heavy but resilient wire having a that when the packages are in wor body part 14, one end portion bent off in one direction to form the trunnion 15 and the other and considerably longer end portionbent off in the other direction to form a stand ard or upright portion 16 and itself bent off and formed with a tapering return 17 which constitutes what I have termed the spindle to enter the axial hole of package A which is assumed to have such hole too smallto admit the tapering spindle without jamming, which thus gri s and holdsthe package. An important eature of my invention is here to be noted: The arrangement of the two carriers for any bracket is such (Figs. 1, 4 8 and 9) king posi-' tion the spindle and trunnion of each carrier are atopposite sides of the upright 3, so that their body parts 14 lap each other (or here intersect), thus producing a most compact arrangement while permitting each loaded carrier to be swung to dofling position (dotted lines Fig. 4) with ample clearance for dofling and without interference with the other loaded carrier. Otherwise stated, in the working position each pivoted carrier here crosses the corresponding upright 3 betweenits pivot and package or load carrying portions. In the worln'ng position of a carrier its body part is interposed between up right 3 and lug '12; when it is in dofiing position it is between lug 12 and stop 11a, or engaged in notch 12a. To move it from either position requires simply sufficient force to cam it over the lug. Since the pivoting level of the two carriers is here the same the body part of one may have a portion. thereof bent downward, as at 14a, Figs. 2, 5 and 6, to clear the corresponding portion of the other when they are in their crossing relation-to each If the package is not a cone, as in Figs. 1 to 4, with a large axial hole, but consists of windi gs on a spool or other core B having a small ole, as the spools in Figs. 7 to 9, the bent-off portion 16 may have its bent-off ex- (0 tremity or. spindle plain, or without the return, as at 17 a in these latter figures.

With respect to a radius from its pivot at 13 each carrier has its package supporting portion or means 17 arranged to support the 76 package with its axis crossing and substantially perpendicular to such radius and the yarn package is arranged on said means so as to be crossed substantially midway of its length by said radius. Therefore, while each yarn package may stand in delivering position with its axis alined with'the yarn guiding means at the end of arm 7, in swinging 1 from that. position the arc of travel of. the extreme point of the entire swinging structure is one of the shortest possible radius, whereby a greaternumher of such structures side 'by side can be accommodated in the frame than would otherwise be possible.

The tension means (incidentally also a guiding means) hereih set forth for example, and preferred, is essentially the same as that set forth in my copending application Serial No. 525,600, filed March 27, 1931. For the present purpose it is suf'ncient to describe it 05 riefly as follows: On the end of arm 7 is a plate 18 having a depending le 18a in which a spindle 19 is pivoted to roc toward and from the observer in Fig. 2, being suitably limited to a short are of movement and normally urged from the observer, as by gravity. On this spindle is a revoluble pulley 20 sub ject to the braking action of a weighted nonrevoluble disk 21 resting on the'pulley and pressing it against a non-revoluble support .22 on the spindle. The yarn .O extends from the package A (or B) to and around the puliley in at least one completeturn and then toward the observer (compare also with Fi 1). Draft on the yarn, if the pulley 1s snubbed thereby, is opposed (here) by two .forces, i. e., the force normally holding the spindle and pulley from the observer in Fig. 2 and the braking action exerted on the pulley. This snubbing is here effected by a 115 light drag on the yarn between thepulley and package A (or B) produced by two superposed disks 23 confined in superposed relation to each other by three pins 24, but not so that gravity acting on the top disk will not be free to urge it toward the lower disk with consequently a certain degree of pressure on 1 the yarn (which travels between them and is bent in an angle around the central pin) and thus creates the drag. I

In Figs. 1 to' 8 one such tension (guiding) means serves two packages, and the spindles of the latter are arranged so that the axes of said packages converge toward such tension means, common to them. In Fig. 9 the arm 130 7 has a cross-extension 25 carrying two such means, one for each ackage, whose spindles are so arranged that t e axes of the two packages are alined with the respective tension means.

When the creel is tends from one of supply to and around its tension (guiding means and then to and through the reed or equivalent (Fig. 1). The supplies may be superposed on each upright in any number (Fig. 3), those at any one level delivering their yarns in a horizontal sheet. That pack age of any supply which at a given time is delivering yarn has its tail end (or the end first wound in forming the package) spliced, as at C by the attendant to the leading end (or end last wound on) of the companion package according to the well known custom. When the first package is exhausted the yarn will'thus proceed to deliver from the second one without interruption, the attendant then replacing the first package by a fresh one and splicing the tail end of the yarn of the second package to the leading end of the fresh package; and so on. The attendants position for these purposes, it will be seen, is outside of the creel.

In a creel, the combination of support- .ing structure and a pair of yarn package carriers vpivoted therein on substantially parallel axes and lapping each other and each pivotally movable on 1ts pivoting axis, said carriers having means with the package axes extending in the same general direction when the carriers lap each other.
