9 Claims This invention relates to yarn package supporting frames or creels such as are used, for example, in connection with apparatus for beaming or balling warp yarns in preparation for weaving or subsequent processing.

My invention is in part directed to refinements in yarn package supporting and yarn guiding means that favor greater structural compactness of creels with proportionate enlargement of their capacities.

Another object of my invention is to provide, in connection with creels, simple and reliable means for restraining and preventing entanglement of fly and also coils of yarn prematurely released from the packages in consequence of inherent springiness or to twist reaction of the yarns. My invention is thus particularly advantageous in warping stiff yarns, for example of rayon, as well as closely twisted yarns of other materials.

I also aim to facilitate overend withdrawal. of the wraps from the yarn packages through provision, in association with individual supports for the yarn packages, of a novel form of guide which is easily threaded, and capable of maintaining an even tension on the yarn while redirecting it as it leaves the creel.

Still other objects and attendant advantages of this invention will be manifest from the following detailed description of the attached drawings, wherein Fig. I is a fragmentary elevation showing a section of a multi-wing creel embodying the present improvements.

Fig. 11 is a plan view of the creel section.

Fig. III is a fragmentary illustration, viewed as indicated by the arrows III-J11 in Figs. I and II and drawn to a somewhat larger scale, showing in greater detail one of the yarn package holders and associated yarn guides.

Fig. IV is a view on a still larger scale showing one of the yarn guides in plan.

Fig. V is a detail cross-sectional view of the guide taken as indicated by the arrows V--V in Fig. IV.

Fig. VI is a fragmentary plan view of a reserve supply or magazine creel embodying my present improvements; and,

Fig. VII is a fragmentary elevation of the creel shown in Fig. VI.

Referring first more particularly to Figs. I and II, the numeral 10 comprehensively designates one section of a creel and 11, eye boards such as are ordinarily employed with creels in a warping apparatus. The frame of the creel 10 comprises a base board 12 from which rise a series of rod uprights 13, 14 which are joined at their tops by a horizontal 15 which is connected in turn by cross horizontals, whereof one is indicated at 16 Fig. II, with the top horizontal of a similar. creel section not illustrated. Secured with provision for vertical adjustment on each of the uprights 14, is a series of brackets 17, each of which has a pair of arms 18 that project horizontally outward in opposite directions, see Fig. III. Upstanding from the terminal bosses 19, at the ends of the bracket arms 18, are studs or stems 20 whereover the cylindric yarn packages P are mounted with capacity for axial freedom, for a purpose later on explained. Engaged between a shoulder on each stem 20 is a member 21 of dished cross-sectional configuration which has substantial circumferential projection beyond the yarn package P. As shown in Fig. III, the member 21 has a lining 22 of felt or like material, and serves to support the yarn package P upright, resting on its lower peripheral edge, with capacity to gravitate incident to diametral contraction of said package as the yarn Y is unwound therefrom.

Overend withdrawal of the yarns Y from the packages P is determined by arm-like guides 25, of which there is a pair associated with each holder bracket 17. As shown, each pair of these guides 25 serves the yarn packages P on the bracket 17 immediately beneath them, this being true of all in the series on each of the creel verticals 14. In order that they may be individually moved out of the way to facilitate replacement of the yarn packages P upon exhaustion, the guides 25 are adj ustably secured to vertical pivot pins 26 engaged, with freedom for rotation and axial shifting, in bearings 27 respectively afforded by the arms 18 of the holder brackets 1'7, such bearings being cqui-distant from the central anchorage bosses 28 of said brackets. For the purpose of maintaining the guides 25 yieldingly in active position above the yarn packages P and in line with the brackets 17, I provide means including, in each instance, a collar 29 at the top of the pivot pin 26, said collar having a cam lug 30 to engage a notch 31 in the bracket 17. When a yarn package P is to be replaced, the corresponding guide 25 is simply swung on its pivot pin 26 out of the way, incident to which the cam lug 30 will ride readily out of the notch 31 of the bracket 17, in a manner obvious from Fig. III.

Referring now more particularly to Figs. IV and V, it will be observed that each guide 25 is in the form of a casting with a hollow shank 32 to receive a stem 33 that reaches (as shown in Fig. III) laterally from the pivot pin 26, and a horizontal annular head 34 in continuation of the flattened portion 35 of said shank which is pierced, as at 36, with provision of an eye to receive the yarn Y from the package P. The guide 25 is moreover formed with a substantially semicircular guard 37 which is concentric in respect to the annular head 34 and occupies a plane slightly above that of said head. As shown, the guard 3'] lies at right angles to a line intersecting the eye 36 and a boss 38 sustained centrally within the head 34 by radial spokes 39, said boss supporting an upstanding stud 40 of porcelain or the like. On this stud 40 is placed a pair of frcely-revolvable opposingly-cupped tension disks 41, 42 whereof the peripheral edge of the lowermost one 42 rests, as shown in Fig. V, upon the spokes 39 of the head 34 so as to bear thereagainst with a slight amount of friction.

In the operation of the creel, since the packages P rest on their lower peripheral edges, they continuously settle downward in the dished supporting members 21 under the influence of gravity concurrently with diametral contraction as the yarn Y is unwound from them. Accordingly any fly or coils of yarn Y prematurely released as a consequence of inherent springiness or twist reaction in said yarn is prevented from entering beneath and becoming entangled under the package P. Here, the felt covering 22 orthe dished supporting member 21 performs an important function in that it restrains the expansion of prematurely released coils of the yarn Y sliding down along the surface of the package P, and thereby prevents them from expanding beyond the confines of said members. With the guides 25 in the active positions illustrated, the

eye 36 is in each instance coincident with the axis of the package P beneath, with determination of overend withdrawal of the yarn Y from such package. In issuing from the eye 36, the yarn Y is angularly diverted enroute to the tension disks 41, 42, as a consequence of passage about a rounded abutment 44 at the region of mergence of the guard 37 with the shank 32 of the guide 25, as shown to best advantage in Figs. IV and V, the aforesaid abutment being glazed in practice to provide a smooth long wearing anti-frictional surface. By passage around the porcelain stud 40, the yarn Y is again redirected so as to leave the guide 25 substantially at a right angle on its way to one of the eye boards 11, incident to which it is passed under the guard 37. By cooperation with the abutment 44, the guard 37 confines the angular travel of the yarn Y to a horizontal plane, substantially coincident with the meeting plane of the disks 41, 42. By virtue of such compound angular diversion of the yarn Y and subjection to the action of the disks 41, 42, it is maintained under light but uniform tension as it is pulled away from the creel. In threading, the yarn end, from the package P is first drawn through the eye 36 of the guide 25, a loop then formed therein which is carried up through the interval between the guard 37 and the head 34, and the loop finally engaged between the tension disks 41, 42 around the porcelain stud 40.

Referring now to the magazine creel shown in Figs. VI and VII, the yarn packages P are mounted in pairs on the horizontal extremities of swivel members 45, which are swingable about upstanding pivot studs 46 in the ends of brackets 18a secured in vertically-spaced relation to the uprights 14a of the creel. The center studs or pins 20a for the yarn packages P are inclined toward each other with their axes intersecting the eyes 360. of the guides shown at 25a. These guides 25a. are exactly like the guides 25 of Figs. I-V, but in this instance they are immovably secured to the brackets 18a for maintenance of their eyes 360. in vertical alignment with the pivot studs 46 of the swivel members 45 immediately beneath them respectively. Here again, I individually associate with the studs 20a, felt lined saucer-like yarn package holders 21a which permit gravitation of the packages P and function to check the fly of the yarns Y in the same manner as described of the holders 21 in Fig. 111. In use of the magazine creel, the leading end of the yarn Y of one package P of each pair is spliced to the tail end of the yarn Y of the other package P, as shown in Fig. VII, for continuance of the supply when the first package P is exhausted. When replacement becomes necessary, the attendant simply swings the individual swivel member 45 to a transverse position, as shown at the center of Fig. V, whereupon access is readily had from opposite sides of the creel for interchange of a new yarn package P for the empty package core.

From the foregoing it will be seen that I have provided a system of yarn package supports and associated guides for both plain and magazine creels which greatly facilitate replacement of the yarn packages and threading of the yarns, and which, moreover, permit very close grouping to the advantage of greater compactness of the creels and proportionate enlargement of their capacities.

Having thus described my invention, I claim:

1. In a creel, individual holders to support cylindric yarn packages, individually-associated proximately-positioned guides each having an eye coincident with the axis of a subjacent holder to determine overend withdrawal of the yarns from the packages, a pivotal support for each guide to which the latter is adjustably secured, and means whereby each pivotal element may be axially shifted for rotation so that each guide may be moved out of the way to facilitate replacement of the packages upon exhaustion.

2. In a creel, individual holders to support cylindric yarn packages upright, individuallyassociated proximately-positioned superposed guides each having an eye coincident with the axis of a subjacent holder to determine overend withdrawal of the yarns from the packages, an upright support for each guide to which the latter is adjustably secured, and means whereby each upright support may be axially shifted for rotation whereby the respective guides are movable out of the way to facilitate replacement of the packages upon exhaustion.

3. In a creel, individual holders to support cylindric yarn packages upright, individuallyassociated proximately-positioned superposed guides each having an eye coincident with the axis of a subjacent holder to determine overend withdrawal of the yarns from the packages, a vertical support for each guide to which the latter is adjustably secured, and yieldable means coacting to effect vertical axial movement of said support for rotation to enable independent horizontal swinging movement of the guide out of the way to facilitate replacement of the packages upon exhaustion.

4. In a creel, holders to support cylindrical yarn packages, individually-associated proximately-positioned guides each having an eye 00- incident with the axis of a subjacent holder to determine overend withdrawal of the yarns from the packages, a vertical support for said guide to which the latter is adjustably secured, said support being mounted with freedom for vertical shifting and rotation to enable independent horizontal movement of the guide out of the way to facilitate replacement of the packages upon exhaustion of the same, and individual means to yieldingly-maintain the respective guides in active position.

5. In a creel, a series of vertically arranged brackets including holders for supporting cylindric yarn packages in upright position, a yarn guide adjustably supported by a pivotal pin from each holder bracket proximate to a yarn package on the subjacent bracket and having an eye coincident with the axis of said package, and individual gravity cam lug and notch means normally maintaining the guides yieldingly in active position, said cam lug when moved out of the notch axially shifting the pivotal pin for free rotation.

6. In a creel, a series of vertically arranged opposing brackets with terminal holders, each bracket supporting a pair of cylindric yarn packages in upright position, a pair of pivotal pins journaled in the opposing brackets each supporting an adjustable yarn guide proximate to the yarn packages on the subjacent bracket, each said guide having an eye for adjustment into coincidence with the axis of the associated yarn package, to facilitate replacement of a package upon exhaustion of the same, and means afiording the respective pivotal pins individual rotative and axial movement.

7. In a creel, a series of vertically arranged holder brackets each supporting a pair of cylindric yarn packages in upright position, a pair of yarn guides supported by vertical pivot pins journaled in each holder bracket proximate to the yarn packages on the subj acent bracket, means whereby each yarn guide is adjustable to bring the eye therein into coincidence with the axis of the associated yarn package, a gravity cam lug on each pivot pin, and coacting notch means in the brackets, said cam lugs when moved out of the coacting notches enabling said pins to be rotated but when engaged in the notch means yieldingly maintaining the individual guides in active position.

8. In a creel a laterally and vertically-adjustable guide with an eye therein to determine overend withdrawal of yarn from an upright cylindric package, said guide being supported by a pivot pin from a bracket, a collar on the pivot pin having a cam lug for coaction with a notch in the bracket whereby said pivot pin is adapted for simultaneous vertical and horizontal rotative movement, and a holder on the bracket affording the package axial freedom while preventing lateral displacement thereof.

9. In a magazine creel, a series of verticallyarranged brackets with swivel members each adapted to carry a pair of yarn packages positioned at an inclination to each other for overend withdrawal of the yarn from said packages in succession, associated guides at the intersection of the respective package axes, each said guide being supported by a pivot pin from the superjacent bracket, means whereby said guides may be vertically and horizontally adjusted, and individual package holders on the swivel members.
