6 Claims.

The present invention relates to creels or spool stands, and has for its object to provide an improved yarn delivery arrangement, whereby yarn ends leading from a large number of separate packages or spools may be delivered to a twisting or other textile machine, without the individual yarns rubbing against each other, in advance of the twisting or other operation.

According to the invention, the improved delivery arrangement is characterized by the fact that each yarn is withdrawn endwise from its package, and is guided separately through an individual tensioning device, to the point of twisting. As a result, yarn ends from adjacent packages in the creel, do not come into contact with each other until they reach the point of twisting, thereby eliminating any chafing or rubbing between separate yarns, such as would produce defects in the twisted product. The above and other advantageous features of the invention will hereinafter more fully appear from the following description, considered in connection with the accompanying drawings, in which:

Fig. 1 is a view in side elevation of a portion of a creel provided with a yarn delivery arrangement embodying the invention.

Fig. 2 is a View in front elevation of the parts of Fig. l, as viewed from the left.

Fig. 3 is a fragmentary view illustrating individual adjustment of the yarn guides for the spindles.

Fig. 4 is a horizontal sectional view along the line 44 of Fig. 2, looking in the direction of the arrows.

Fig. 5 is a fragmentary view, in perspective, of a yarn guide arm and its holder.

Referring to the drawings, the creel consists of a base I providing a number of upright frames 2, each carrying spindles 3 in spaced vertical alinenient. The spindles 3 carry yarn packages 4 of usual form, and the present invention contemplates an improved delivery arrangement for conducting individual yarn ends 5 to the top or feed rolls 6 of a twisting machine T, of any desired type, for twisting two or more yarns together as they are drawn from the packages 4.

As best shown in Figs. 1 and 2, a series of brackets 1, extending upwardly from the base I, provide lugs 8 for receiving and supporting vertical rods 9 spaced at intervals adjacent to each row of yarn packages 4, as supported by a frame member 2. Each rod 9 carries a series of spaced collars I0, corresponding to the number of yarn packages 4 in a vertical row, with each collar Ill serving to support an arm ll carrying at its end a yarn guide l2 in the form of a pigtail, having its opening or eye substantially coinciding with the axis of a spindle 3. Each arm II is bent to provide an end portion 13 extending substantially parallel to the axis of the associated spindle 3, with the guide l2 extending laterally from the portion l3. Each arm H is turnable on its supporting rod 9, and the collar I 0 on which the arm rests, provides means for supporting the arm II in different angular positions.

To this end, each collar It) provides a notch l4 for receiving a projection l5 provided on the under side of the associated arm II, and normally, the weight of the arm I l is sufiicient to maintain the projection l5 in engagement with the notch I4. Each collar It) provides a set screw It for engaging the rod 9, and by setting the collars H) for a vertical series of arms I I with their notches I4 in slightly different angular relation on the rod 9, the associated yarn guides l2 can be ofiset horizontally with respect to adjacent spindles 3, as shown in Fig. 3, for a purpose which will shortly appear.

Referring again to- Fig. 1, a rail H is horizontally supported by brackets l8 beneath the brackets 1, and supports a series of yarn tensions IQ, of the type providing lightly engaging surfaces 20, between which yarn may be drawn, to exert a retarding effect thereon. As best shown in Fig. 4, th tensions 19 are arranged in pairs in symmetrical relation with respect to a series of guides 2| mounted on a rail 22 supported by the brackets l8 in front of the rail H. A single guide 2| is thus provided for each pair of tensions l9, while a rail 23, behind the rail I'l, carries a series of guides 24 corresponding in number and spacing, to the tensions l9.

Referring now to a vertical row of yarn packages 4, such as is shown in Fig. 2, the yarn I from each package is led endwise to the guide I2.

of the associated arm II, and then downwardly. Due to the differences in the angular settings of the collars ID on the rod 9, the guides I! are spaced horizontally as viewed in Fig. 2, and so the yarns passing therethrough are appreciably spaced apart. This spacing between yarns 5 is maintained positively as they pass to the guides 24 by a multiple guide l2a on the lowermost arm I l, which as shown in Fig. 2, provides a series of spaced eyes. The yarns then pass forwardly through a pair of tensions l9, and come together at the single guide 2|, through which they pass to the feed rolls 6 of the twister. Therefore, when a given pair of yarns are drawn from the of their associated collars It, so as to horizontal ly offset the guides 82 not only withrespect to' each other, but also with respect to the guides l2 and I2a of the pair of yarn packages immediately below. As a result of such adjustment of the guide arms H, the yarns 5 leading downwardly from all of the packages of any vertical series, engage the lowermost multiple guide lZa at different points, definitely spaced from each other by the separated eyes, from which the yarns pass downwardly to the individual guides 24 leading to the associated tensions l9. Cerisequently, there is no interference between the yarns prior to their being led together in pairs, substantially at the point of twisting, 1

As best shown in Fig. 2, the spindles 3, as supported'on alternate frame members 2, are staggered with respect to each other, as indicated by the dotted line showings of packages 4, on opposite sides ofthe vertical series of packages, shown in full lines. By reason of this staggered arrangement of the spindles, it is possible to readily doff any spindle 3, by swinging its associated guide arm- H into the dotted line position. This leavesthe spindle being doffed absolutely clear, thereby making it possible to place a fresh yarn package in position thereon, without in any way interfering with the with drawal of yarn from the packages as supported in adjacent vertical series of "spindles. guide arm H is swung back for doiiing, the projection -l5 thereon readily lifts itself out of the notch M on the associated collar ill, and when the arm has been turned through 180, the projection again seats itself, to frictionally maintain the arm H in. the dofiingpositio'n. V From the foregoing, itis apparent that by the present invention, there is provided an improved delivery arrangement for creels, particularly adapted for use in connection with twistelrs, whereby yarn ends that are tobe twisted together, are. drawn from the yarn packages and conducted individually to substantially the point of twisting, without rubbing or chafing.

We claim:

1. A yarn delivery arrangement for creels, comprising means for supporting a plurality of yarn packages one above the other, meansfor drawing individual yarns from said packages to a point of twist, and a plurality of yarn guides angularly adjustable with respect to an axisat right angles to the parallel axes of said packages for causing endwise withdrawal of separate yarns from said packages, and their passage to said point of twist in spaced relation.

2. A yarn delivery arrangement for creels, comprising a plurality of spindles for supporting yarn packages one above the other in a vertical row, a multiple eye guide bar extending horizontally be- .low a row of spindles, and a series of yarn guides individually adjustable with respect to the axes of said spindles, for causing the endwise withdrawal of separate yarns from said packages and conducting said yarns to spaced eyes on said guide bil while entirely separated from each other.

3. A yarn delivery arrangement for creels, comprising a plurality of spindles for supporting yarn rows, with the spindles of one row offset with respect to spindles in adjacent rows and a series of pivoted yarn guides for each row of spindles, with each guide movable into the space between spindles of an adjacent row, for dofling of a spindle.

5. A yarn delivery arrangement for creels, comprising a plurality of spindles for supporting yarn packages one above the other inspaced vertical rows, with the spindles of one row vertically offset with respect to the spindles in adjacent rows, and a series of pivotally mounted yarn guides for each row of spindles, with each guide angularly adjustable with respect to the axis of its associated spindle, and movable into the space be tween spindles of an adjacent row for dofiing of FRANK B.
