YARN-GUIDE non srmnIne-munns.

To all whom it may concern:

Be it known that I, JOSEPH HILBERGER, a citizen of Germany, residing at Garfield, county of Bergen, and- State of New Jersey, have invented a new and useful Yarn-Guide for Spinning-Mules, of which the following is a cross section through my improved yarn guide and cooperatingiparts; Fig. 2 a plan of part of, a mule-carriage provided with the yarn guide, and; Fig; 3 adiagrammatic side elevation of theimulyeirriageandjcoacting arts.- p The numeral v v 'mulecarri'age which receives. helizon allyli,i'eciprocative movement in any Suitable manner. Carriage 10 is provided with aser'i'es ofconventional inclined spindles. .11 around which the spun threads 12=f.' are wound, in vconiform layers, said spindles being driven from a common transverse shaft 13 by means of cords 14.

The strands il that'go to make up each yarn or thread 12 are delivered from a suitable number" of spools 16 andare passed from a common idler 17 between a suitable number of draft r0lls'1'8. During the movement of carriage 10 away from said rolls, the yarn is twistedgbymeans of its fast rotating spindle 11, .whileduring the return movement of thej-carriage, the thread thus formed is woundjon said spindle to form a bobbin 19. The thread formed during each outward movement 0f carriage 10 ;is wound upon the previously finished bobbin section in the form of a=conical layer 20 by means J of arr-oscillating. yarnguide. 21, another guide 22 'being provided above guide 21.

withniylimproved construction, guide 21 is made in' the form of a transverse barshown to'be of oblongrectangular cross section, the bar being mounted in an inclined position relatively to the spindle-axes, so

that the yarn passes over one of the short sides or edges 2150i such bar. In other Specification of Letters Patent. Application filed June 18, 1913. Serial No. 774,303.

section lies substantially in the line dividing the angle that is formed between the two yarn-runs 12* and 12 (Fig. 1). Bar 21 is carried by the free ends of a series of'sickleshaped arms 23 fast on a rock shaft 2 1 that receives oscillating movement through lever ide the words, the longitudinal axis of the bar-cross-. I

yarn for winding the desired coni orm layers. By thepeculiar shape and position of guide 21, anyfibers which may occasionally become untwisted from the yarn, cannot possibly wind around the guide, by which winding the yarn would be held back, while slings'would be liable to be formed during the inward movement of the carriage.

It is furthermore necessary that all of-the bobbins be wound in the same sense, Fig. 2 showing all bobbins to be right-wound. It

is obvious that for this purpose all of the bobbin-spindles must receive ,a like motion through their cords 14 from shaft 13. But it frequently happens that upon the brealc age of anyone cord 14, the operator so refits said cord through carelessness,'that in lieu of the right-wound bobbin desired, a left-wound bobbin will result. In order to eliminate any such wrongly wound bobbins, I provide the bar 21 opposite each bobbin with a cutting member located in the range which the yarn would traverse while winding the bobbin-cone in the undesired direction. Thus for the right-wound bobbin shown, in which the yarn sweeps the range m 1 the cutting member should be placed opposite the range B -y, z. e. that range which would be swept by the yarn of a leftwound bobbin. Calling that art a of the bobbin-cone which takes up t e yarn from bar 21, the active zone, and that part b bobbin would be wound in the opposite sense, the inactive zone, the proposition may be so stated, that the cutter on" the bar is lo-' cated directly infront of the inactive zone, while clearing or not extending across the active zone. With the example illustrated, each cutter is formed by providing-bar 21 with a sharp-edged slit 27 that extends from edge 21 a limited distance into the body of said bar. It will be seen that by the construction described, the yarn will be automatically cut, whenever any spindle rotates in the wrong direction, so that the operator which would take up the yarn, in case thepair of yarns that owing to their whirling In order to adapt bar 21 to be set for leftwound spindles as Well as for right wound spindles, it is adjustably fitted to arms 23, so that cutters 27 may be made to face either the zones a or the zones b. For this purpose, bar 21 is shown to be slidably supported in arms 23 and to be held in the selected position by set screws 28.

Cutters 27 have the additional important function of cutting either one or both of a motion during twisting, may become entangled between the draft rolls 18 and guide 22. During the subsequent winding of the doubled yarn thus formed, the latter will be laterally deflected from the bobbins and then drawn over the cutters, so that in this Way the winding of defective bobbins is prevented.

lt claim:

In a device ,of the character described, a mule-carriage, a plurality of inclined bobbin-spindles rotatably supported thereby, a rock shaft journaled in the carriage, a plurality of arms secured to the rock shaft, 21 yarn-guide, means for adjustably securing said guide to the arms, and yarncutting means on the guide that are arranged side- Wise of the normal paths of the yarns and in front of the inactive zones of the bobbins.
