GUIDE FOR YARN.

Application filed March 5, 1925.

T 0 all 107mm it may concern:

Be it known that I, lsinon Bnnnnons, acitizen of the United States, ands resident of the borough of Brooklyn in the county of Kings, city and State of new York, have invented certain new and useful Improvements in Guides for Yarn, of which the following is a specification.

My invention is adapted more especially for use in cone winding machines although it will be apparent that the same may be used on other types of machines in which yarn or similar. material is unwound from a skein. In the drawing T have shown my invention applied to a cone winning machine, only such parts of the machine being shown as is necessary to illustrate the application of my invention. In cone winding machines it is customary to place the individual skeins of yarn upon a pair of reels and a series of reels are generally arranged in double rows at the front and back of the machine. The yarn is taken from each skein and is wound into the form of a cone or bobbin and as the yarn is drawn from the skein the latter moves around like a belt upon its reels. The skeins cannot be placed under great tension between the reels as there would be too much resistance or tension upon the yarn, which would cause the latter to break, so a light tension is usually furnished by making the lower reel of the pair swing by gravity on a pivoted arm. Owing to the light tension on the skein of yarn, one or more of the strands often jumps over the flanges of the reels and the strands of adjacent skeins often entangle with each other interfering with the operation of the winding machine.- The object of my present invention is to provide a simple and inexpensive guide for straddling the upper and lower runs of each skein of yarn to prevent the yarn from jumping over the flanges of the reel and also to prevent the yarn of adjacent skeins from becoming entangled. It is not practicable to enlarge the flanges of the reel beyond certain reasonable limits as this increases the weight of the reels and thereby increases the tension of the yarn beyond practical limits. The present device, while serving to guide the skein and avoid the difiiculties mentioned above, nevertheless does not increase the tension upon the yarn.

Figure 1 is a side elevation showing the parts of a cone winding machine with which my present invention is associated,

Figure 2 is a sectional View thereof-taken on the line 22 of Figure 1,

Figure 3 is an end view of the parts shown in Figure 1, and

Figure is a perspective view of the guide detached from the machine.

In the drawing I have shown the central shaft 1 on which are mounted brackets 2 for supporting the diverging arms 3, lwhich form the supports for the inclined skeins of yarn, the arms 3 being directed obliquely toward the front of the machine and the arms l being directed obliquely toward the rear of the machine, in the usual manner. These arms are pivoted to the bracket 2 on the pivots 5 the inclination of the arms being adjustable by means of pins inserted in the apertures 6 of the bracket. As the several arms in the machine are duplicates of each other a description of one will suffice for all. Usually each arm 4 supports a pair of reels at each side of the arm, each pair of reels serving to hold a skein of yarn.

each other to support and guide a skein of yarn 9. At the opposite side of the arm l there is a similar pair of reels 7 and 8 serving to support another skein of yarn 10. There is a clamp 11 which is adjustable along the arm i and it carries the angular bracket 12 which projects away from the arm 4 and on its outer end it supports a shaft 13 on which both reels 7 are adapted to freely revolve. By adjusting the clamp 11 along the arm 45 the reels 7 may be separated from the reels 8 the required distance to hold any size skein upon the reels. In the form shown herein each reel comprises a hub 14 on which are mounted parallel flanges 15 which are connected by cross spokes 16 with which latter the skein engages.

The lower reel 8 of each pair is mounted to revolve freely upon the shaft 17 which is carried on the free end of a bracket 18 which is pivoted at 19 to the arm 4. The reels 8 tend to swing from the pin 19 as the center and this gravitational action places the skein In the drawing I have shown anupper reel 7 and a lower reel 8 1n hne with which is supported upon the reels 7 and 8 under light tension. A strand of yarn 2O usually is taken from the skien near the upper reel, '7. The improved guide shown herein is preferably mounted by means of a bracket 21 and a clamp 22 upon the arm and the position of the bracket may be adjusted along the arm at by means of the set screw 23. In the free end of the bracket 21 there is journaled a short shaft 24 the position of which may be adjusted and fixed by means of a set screw 25. A pair of guides may be supported upon this shaft 2% for the skeins at opposite sides of the arm 4 and as these guides are duplicates of each other a description of one will apply to both. This guide is preferably made of wire or red bent into the form o'l a series of loops in the manner described below. The upper horizontal end :26 oil the guide extends through an aperture in the shaft 24. From the portion 26 the wire is bent downwardly at 2? thence looped at 28 to form a return portion 29 ex tending parallel to the portion 2?. it the upper part of the portion 29 the rod is bent at an angle to form a cross piece or connection 30 extending substantially at right angles to the portions 27 and 29, and the rod is again bent downwardly to torm a portion 31 parallel to and spaced from the portions 27 and 29. At 32 the rod is again bent into a loop and it then extends upwardly to form a part 33 which is parallel to the parts 27 29 and 81. The loops 28 and 32 are preferably turned outwardly in divergent relation as shown in Figure 3 to facilitate the placing of the guide over the skein.

When skein of yarn is being applied to the reels 7, 8 the guide as a whole, together with the shaft may be swim so that the guide is out of the way while the sliein is being mounted, or. the skein may be inserted between the sides oi the guide from below. In either case the skein may be' attached as quickly it the guide were not present. When the skein is in place on the reels 7, 8 the guide will straddle both the upper and lower runs the )ortions 27 and 529 of the guide eittending downwardly on one side of the skein. and the portions 31. 33 extending l wnwardly at the opposite side of the skein the cross member 30 ng above the upper ru oi. the skein. its the space between the sections 2? and 29 and the sections 31, 33 is apprznzimately the same as the distance between the flanges l5 of the reels there will be approximately no friction between the guide and the yarn. it there is a tendency for the yarn to jump the flanges of the reels or for the yarn of adjacent reels to flop sidewise, this will be opposed by the guide. It is preferable to make the guide extend below the lower run of the skein as shown in the drawing in order to protect any dropping strands oi the yarn. The guide may be adjusted in its position along the arm 4; and its angular relation to this arm may be adjusted by means out the set screw 25 which controls the rocking oi? the shaft 2%. By this simple and double adjustment the guide may be arranged. to control the yarn at the critical point regardless of the length of the skein and the angle of inclination of the arm 4.

Having described my invention, what I claim is:

1. A guard for guiding a skein of yarn while being unwound on a pair of reels, comarising guiding members adapted to straddle the runs of the skein of yarn between the supporting reels a cross member connecting said guiding members above the yarn, said guiding members being free or disconnected below the yarn, and means for supporting the guiding means.

2. A guard for guiding a skein of yarn while being unwound on a pair of reels, comprising guiding members adapted to straddle the runs of the skein of yarn be tween the supporting reels, and means for supporting the guiding means, said supportin." means bein adjustable in the direction oil. the length of the skein of yarn and adapted to permit the guiding means to be swung out of the path of the skein.

A guide for yarn comprising a wire or red bent to form a plurality oi? loops connected by a connecting portion whereby the said loops may be disposed on opposite sides of a skein of yarn during the unwinding thereof to guide the yarn.

4-. A guide for yarn comprising a wire or red bent to form a U shaped loop the arms of which are substantially parallel. thence crosswise to form a connecting member at one end of said loop and thence bent to form a second U shaped loop the arms of which are substantially parallel, said ll shaped loops being spaced apart in substantially parallel relation.

The combination with a yarn winding machine having an arm supporting a pair of spaced reels for holding the sl-cein of yarn, a support adjustable along said arm, and guide carried by said support and comprising members arranged to straddle the skein of yarn between said reels and to prevent lateral displacement of the yarn.
