]Be it known that Ill, SILAS E. BAILEY, a citizen of the United States, and resident Ghemung county, State useful Improvements in Guide and Tension Devices for Removing Snarls, Kinks, &c.-,

the followin' is a specification.

fiiy invention relates to guide and tension devices for yarn and thread.

It is well known that when thread or yarn a cop or cone upon is pulled or drawn from there will be more which it has been wound or less slack in the thread on account of the twist given to the thread when it is wound on the top or cone, When unwinding the slack will cause kinks, loops, snarls and so forth to form in the thread. The yarn or thread, carrying snarls, kinks, etc., must not be delivered in this condition to the knitting or sewing yarn will be caught in the needle, the goods will be damaged, and other damages and delays will result.

The principal object of my invention therefore is to provide a simple form of a combined guide and tension device which is especially adapted to remove these snarls,

k nks, loops,

before it is delivered to theknitting, sew- .ing or other machines in which it-is used. I

The above and other objects and the novel features of my invention will be apparent from the nection apart of this application and in which Figures 1 and 2 are perspective views of guide and tension devices embodying my in-' vention and showing the same mounted on suitable supports; and

Figs. 3 and 4 are enlar ed side views of parts of the guide and tension devices shown 1n Fi s. 1 and 2 respectively.

Re erring to the drawing, lF'ig. 1 illustrates a guide and tension device and its mounting adapted for use with two-thread sewing machines and Fig. 2 shows a similar guide and tension device adapted to be set upon the table of a single thread sewing machine.

Referring to Fig. 1 the heavy metal base B has a vertical standard S secured at its machines in which it is used, else the thread or upper side 18 of the etc., from the yarn orthreadv following description taken in conwith the drawings which constitute the guide eye Gr when the tensiondevice D-consists of a single are connected. Theseeach other in all reupon which is wdund The upper end of length of comparativelystifi, resilient and fits into and downwardly and rearwardly as at-15. At the'lower end of the part 15 the wire is bent downwardly and forwardly as at 16 to form the lower side of the guide eye or loop Gr. At the lower end of the part 16 the wire is bent at 17 rearwardly and upwardly parallel to the part 16 to form the guide eye G. The sides 16 and 18 of th guide eye G are spaced apart.

At the upper end of the side 18 the wire is bent upwardly as at 19 and then downwardly and forwardlyas at 20 substantially parallel to the side 18 of the guide eye G. It will be noticed that the bend 19 is spaced from the part 15 to leave a narrow inlet p assage 21 at the upper. end of the guide eye G through which the thread or yarn may be passed when the eye G is threaded. prevents the thread T from jumping out of there islconslderable slack in the thread T. I

The forwardly extending part 20 of the wire constitutes the shank portion of a'hookshape tension member, the free orflhook end 22 of which extends upwardly on a curve which is substantially a continuation ofv the curvature ofthe shank portion '20. The hook portion 22 prevents the escape of the threador yarn as it is drawn from the tension member even though the yarn is runnin loosely. H

In t 0' form of device shown in Figs. 2 and 1, which is designed for single thread The lower end of'the part 15' Smooth wire circular ,in cross section. One end of the straight portion 14 of the wire is secured in the central opening in the end of the horizontal bar 13. At the outer end of the straight part 14 the wire is bent I D The guide an machines, the heavy metal base B is pro-" The base B hasa standard S mounted thereon and an L-shaped coupling member 24 at the upper end of the standards carries the combined hide and tension device tension device I) is in most respects similar to the guide and tension devices D, D. The tension device D consists of a single length of metal wire circular in cross section and of such a diameter that it will be comparatively stifl'. The wire forming the tension device D has a straight portion 25, the inner end'ofwhich fitsinto and is secured in the opening in the hor zontal part of the coupling member 24. At the up -er end of the straight part 25 the w1re is bent vertically downwardly as at 26 to form the rear side. of the guide eye or loop G. At the'lower end of the side 26 the wire .is bent forwardly as at 27 and then it is bent upwardly as at 28v parallel to but spar-ed from the part 26. The bend 27 forms the bottom of the guide eye G and the upwardly extending part 28 forms the front side of the same. The guide eye or loop G is open at its upperend at 29 so that it may be readily threaded.

At the upper end of the side 28 the wire is bent forwardly as at 30 and then downwardly, and forwardly on a curve as at 31. The part 31 of the wire constitutes the shank portion of the hook-shape tension member of the guide andtension device. The free end of the wire is bent upwardly'as' at 32 on a curve which substantially forms a continuation'of the curvemade by the shank portion 31. The hook portion 32, as explained before, is to prevent the escape of the thread or yarnas it is drawn from the device.

The thread or yarn T may be readily threaded in the guide eyes G or G of the tension devices .and it is then given-oneor Hie-Te tw1sts'W around the shank of the hook shapetension member, the number of twists depending on the tension desired ou the thread when it leaves the guide and tension dew ice. The thread or yarn 1S delivered do wnwardly at about an angle of 45 to the I be ztraightened out since the sides of sewing or othermachine. The pull of the sewing or other machine draws the yarn or thread T from the cone or co upon which it has been wound and t ere is usually some slack between the cone or cop and the tension device. On account of the twist given to the yarn or threadwhen it is wound on the'cone or cop, the unwinding operation and slack will permit the forma tion of snarls, kinks, or loops-L therein. As the thread '1. passes through the guide eye of the device, the loop or snarlL wi 1 usually the e e wili catch the loop and hold it until he runs around and 'bottom of the guide eye and the adjacent part of the shank of the tension member and in its travel across this space all the snarls,

kinks and loops which have not previously been removed will disappear. The device is threaded so that the thread passes under one of the parts 18, 20 in Fig. 3 and over the other part and the device in Fig. 4 is threaded so that the thread passes under one of the parts- 28 and of the eye G and over the shank 31 of the hook portion of the device.

. Due to this arrangement the thread is locked in the device of Figs. 1 and 3 by the invertedloop formed by the sides'l8, 20 and the bend 19 and cannot jump out of this loop. In Figs. 2 and 4 the inverted loop formed by the sides 28,- 31 and thebend 30 locks the thread in the device. The guide eyes or .loops G, G are. deep so as to prevent the escape of the thread or'the kinks and loops therefrom and also to prevent the loops becoming caughtat the bends 19 or 30 at the upper ends of the guide eyes, since if. the

loops are caught on any projections the thread oryarn will break and cause damage and delay; The upper end of the hook portion of each of the tension members of the devices is also ata considerable distance above the part of the shank upon which the thread is twisted so that none of the loops or snarls will get caught on the free end of the device, which would also cause breakage of the thread. The free end of the guide and tension device is resilient and will accommodate itself to slight variations in the tensionon the thread and will thus also prevent some breaks.

It will be seen that the combined guide and tension device is simple in construction and that it may be used with either right or left twisted yarn or thread, since the thread may be twisted on the tension member of the device in either of two ways. The ordinar pig-tail guide is adapted for use only witi yarn or thread twisted one way and the free end thereof is usually whereit will catch kinks in the yarn twisted the other \Xhile I have shown and described the construction in detail it is to be understood that various modifications may be made therein without departing from the 'spirit of the invention. c
