MOLLOY, OF APPONAUG, RHODE ISLAND, ASSIGNORS TO UNIVERSAL WTNDING COMPANY, 01 BOSTON, MASSACHU- SET'I'S, A CORPORATION OF MASSACHUSETTS- CBEEL Application filed July 14, 1928. Serial No. 292,872.

This invention relates to creels for holding cops, cones or packages of yarn, thread or the like to deliver the strand material therefrom in various processes of the textile art.

One object of the invention is to provide an improved creel adapted to support a plurality of nonrotatable cops, cones or in packages to adapt the strand material to be rawn off over the end thereof at a high rate of speed without interferencefrom ballooning and with a uniform tension on all of the ends. Another object of the invention is to rovide a creel in which the supplies are c osely associated to economize in space while permitting free access to the cops and their holders for convenience 1n iecing up the ends and in creelmg and An ther object of the invention is to provide a creel wherein the strand-governing or separating means'may be swung out of the way to permit access to be had to the supply-holders for the purpose of creeling and dofiing, and in piecing up.

Further objects of the invention are, in general, to (provide a creel from which the urn, threa or other strand material may warped or transferred at high speed while at the same time delivering the ends undera moreconstant and uniform tension to improve the quality of the finished prodnet.

The present invention may be embodied in a creel having a form of construction such as described in the following specification and illustrated by wayof example in the accompanying drawings. In the drawig. 1 is a front elevation of the improved creel shown as embodied in a preferred form of construction, duplication of the parts being omitted for the sake of clearness;

Fig. 2 is an end elevation of the creel structure shown in Fig. 1;

Fig. 3 is an enlarged plan view of a portion of the creel showing the strand-governing means or separators in both operative and inoperative position;

. Fig. 4 is a diagrammatic view illustrating the manner of creeling and dofiing the cops arators used on the creel.

In deliverin yarn, thread and other strand materia from non-rotatable cops or other supply packages the resistance to the draft on the strands varies considerably at different points in the delivery. When the cops or supply packages are full, the strands deliver with comparatively little resistance owing to the relatlvely large diameter of the package and the considerable amount of yarn contained in each coil unwound therefrom; while, as the package is reduced in diameter, the coils contain much less yarn and consequently mustuncoil much faster. This increase in the speed of unwrapping of the coils throws the yarn outwardly under the action of centrifugal force, producing what is termed ballooning.

For the purpose of controlling the delivery of the ends from the creel under a constant tension, the yarns are guided throughly the strands are thrown out or released from the tension-devices and become entangled in the projecting parts of the creel. As one feature of the present invention, the

creel is provided with means adapted to minimize the extent of ballooning of the strands and thereby prevent entanglement of the yarns, such means being so constructed that when it is necessary to piece up the ends or to doif and re-creel the supplies, the strands adjacent thereto may be separated or parted and the separators themselves moved out of the way to give access to the supplies and their holders.

Referrin first to Figs. 1 and 2 of the drawings, he preferred form of construction of the creel as herein illustrated comprises a framework or grill constituted by vertical rods or uprights 11 and 12. Th:v rods 11 and 12 may be supported in socketed feet 13 mounted on a suitable base 14: hearing casters 15 which permit the creel to be thereto by bolts or other means. The uprights 11 may be braced from the base 14' by inclined struts 20, the lower ends of which are received in sockets 21 fixed to the base 14, while their upper ends are fastened to the laterallyrojectmg arms of brackets 22 mounted on t e tie-rods 16. Preferably, the struts 20 are provided at each end of the framework as shown in Fig. 1.

As shown in Fig. 2, the rearward uprights 11 of the frame are of heavier construction than the forward rods 12, being adapted to support the supply-holders 23 for the cops or packages which are preferably in the form of cross-wound cones The cones C may be Wound on suitable coptubes or yarn-receivers which are slid onto the supply-holders 23 and retained in place by suitable means as usually employed for this purpose. Preferably, the supply-hold-.

. ers 23 are tilted upwardly so that the weight of the cones tends to hold them in place thereon.

In the present construction the supplyholders 23 are arranged in pairs to su port two cones from a single bracket 24. s illustrated in Fig. 3, the bracket 24 has a central recessed portion adapted to be clamped around the upright 11 by means of a U- k bolt 25. The looped portion of the bolt 25 endgages around the rod 11 opposite to the si e engaged by the recessed portion of the bracket 24. The arms of the bolt 25 pass through spaced openings in the bracket 24 and projecting therebeyond are threaded for the reception of nuts 26 which are screwed snugly against the bracket to draw the parts together.

The manner of mounting the brackets 24 on the uprights 11 is such that they may be adjusted vertically on the creel to locate the supply-holders 23 in proper relation with respect to their associated tension-devices or other strand-guiding means through which the yarns draw. It will be noted from Figs. 1 and 2 that the su ply-holders 23 are arranged on the uprig ts 11 in parallel rows, the construction of the brackets 24 and the spacing of the uprights 11 being such that t e cones C are uniformly spaced apart both vertically and horizontally. The use of duplex supply-holders for the pairs'of cones ing the material carrie by the creel. The

tension-devices 30 are preferably mounted in pairs on the smaller forward rods 12 of the creel frame. In the form as herein shown the tension-device .30, illustrated in detail in Fig. 3, comprises a pair of disks 31 mounted on a in or stud 32 projecting upwardly from a racket 33. The bracket 33 is provided with a central hub 34 adapted to embrace the rod 12, with a set-screw 35 em loyed for clam ingit in place thereon.

he tension-bracket 33 is preferably of duplex construction having similarly formed C, shelf-portions 36 disposed on opposite sides of the hub 34. Each portion 36 of the bracket 33 is rovided with an angularly formed arm 3 carrying a guide-hook 38 for the strand 3 The inner portion of the arm 37 has an opening 39 therein through which the strand 3 draws as it leads from the cone 0. From the guide-hook38 the strand y passes between the tension-disks 31 and around the pin 32', and thence draws outwardly therefrom around a second guidebook 40 on the bracket 33. After the strands y from the whole series of supplies or cones C have been threaded through the tensiondevices in the manner as above explained the ends are drawn oil to one side as shown in Fig. 3 and carried to the warping machine or other apparatus in which the yarn is to be converte Due to the high speed at which the strands draw through the tension-devices 30, the unwrapping of the coils from the cones C causes the strands to fly outwardly under. centrifu al force, resulting in the ballooning of t at portion of the ends extending between the supplies and the tension-devices 30. The balloonin may vary considerably during the unwin ing of the yarn, alternately increasing and decreasing as the resistance is lessened or augmented, res ctively, at the cone. Frequently, the bal oonin becomes excessive and the strand is whip d forwardl toward the tension-device so t at it is liab e to become entangled on the pins 32 and guide-hooks 38 and 40. Should the strand become caught or entangled in the parts of the tension-devices, further delivery of the end from the creel would be prevented 1mm a and the yarn strained and broken. In such case the process for which the yarn is being delivered must be stopped to piece up the broken strand or strands. Frequent interruption in the operation of the apparatus from such causes will therefore greatly reduce production and increase the cost of the product. It is therefore desirable to provide the creel with means for reventing excessive ballooning of the stran s to eliminate entanglement and breakage of the ends and the present invention provides an improved device forthis pur ose.

In the preferred form 0 construction as herein shown the means for preventing excessive ballooning of the yarn in the creel comprises a series of vertically disposed baffle-plates or separators 41 which are arranged in the path of the strands drawing between the cones C and the tension-devices 30. The separators 41 are preferably constructed in the form of rectangular strips of sheet-metal, see Fig. 5, and are perforated along their length to provide a plurality of opemngs 42 through which the strands are adapted to lead. The openings 42 in the sefparators 41 may be circular in shape and o generous size to facilitate the threading of the ends therethrough. The separators 41 are hinged to the frame of the'creel by means as next described to adapt them to be shifted in position for a purpose as later explained.

As shown in Figs. 3 and 5, each separator 41 is provided with a plurality of U- shaped yoke-members 43 constituting the hinges on which it turns. The hinge-members 43 are preferably constructed from sheet-metal and attached tothe metal strip 41 by means of rivets, bolts or the like, the arms of the members being provided with alined openings 44 for receiving the hingepins. A separator 41 is disposed at the rear of each vertical series of tension-devices 30, and for the purpose of hingedly mounting them on the creel the forward rods 12 carry brackets 45, one for each of the hingemembers 43 on the separator.

The bracket 45, shown at the right in Fig. 3, has a notched or yoke-shaped portion 46 embracing the rod 12 with a setscrew 47 therein for clamping the bracket to the rod. An arm 48 projecting laterally from the clamp-portion 46 of the bracket is provided with an offset lug 49 adapted to be straddled by the arms of the hingemembers 43 on the separators 41. Preferably, the arm 48 extendsoutwardly and rearwardly from the rod 12 and the hingemember 43 of the separator 41 is joined thereto by means of a pin 50 passed through its openingsand a hole in the lug 49. The arm 48' terminates in an angularly disposed stop-finger or abutment 51, against which the side of the separator 41 bears when 53 having an opening 54 into which is,

hooked one end of the spring 55. The opposite end of the spring 55 is anchored to 'the end of an arm 56 projecting laterally from a collar 57 surrounding the rod 12 and secured in position by means of a setscrew 58.

The cones C or other yarn supplies are applied to the creel from the front, there being sufiicient space between the pairs of associated tension-devices 30 to permit the operator to pass the full packages inwardly therebetween. But with the separators 41 arranged in operative position at the rear of the tension-devices the open space be tween the rods 12 is reduced to such an extent as to prevent the free passage of a full package through the front of the creel. Accordingly, when'it is necessary to doff the exhausted packages and re-.creel new cones, the separators 41 may be folded rearwardly on their hinges to position them at substantially right-angles to their normal relationship on the rods 12, as shown by full lines in Figs. 1 and 4, and by broken lines in Fig. 3.

s the separators 41 are folded rearwardly their inner edges will engage a step or shoulder 60 on the bracket 45 as shown most clearly in Fig. 3. Inasmuch as the spring 55 is secured to the outer portion of the separator 41, when the separator is folded rearwardly the spring will be carried from one side of the hinge to the other, thereby tending to hold the separators against the .step 60. The retention of the separators 41 in boththeir 0 erative and inoperative positions is there ore automatic, the operator being only required to swing the separator to a slight extent to carry the spring across center.

In the operation of the creel the plurality of ends from the cones C or other supplies livers may be carried on at a faster rate of production and with less wastage of the 3., It will be observed that in addition to the advantages above pointed out the present improved creel provides a most compact and efficient device for the purpose specified. The improved apparatus permits warping yarns at a maximum rate of speed, and when it is necessary to stop the machine for the purpose of replenishing the supply, the empty cone-tubes or yarn-receivers may be eas ly and expeditiously dofied and fresh su plies creeled in their place. The improve construction of the creel further provides means for partingthe rows or banks of strands passing through the tension-devices to facilitate the finding of broken ends and the operation of piecing them up. The invention therefore greatly increases production and efi'ects further economies in the cost of labor.

While we have herein illustrated and described a preferred form of construction of the improved creel, various modifications may be made in the structureand arrangement of its parts and its method of application to various processes of the textile art without departing from the spirit or scope of the invention.
