YARN-GUIDE.

I Patented Jan. 7, 1913.

To all whom it may concern:

Be it known that we, FRANK D. Hancock, and FEsrUs S. RAND, citizens of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Yarn-Guides, of which the following is a specification. v

Our invention'relates to improvements in threador yarn-guides for use on textile apparatus such as winding, spooling or other like machines.

Our invention is especially adapted for use with winding machines in which the yarn or thread leads to the thread-guide from above, and the object of ourimprovement is to provide a device with means to retain the yarnin the guide and to allow easy and quick threading of the guide with the use of one hand only. T

The invention is fully described in the following specification, illustrated by the accompanying drawings, in which Figure l is a front elevation of a winding machine, showing our improved threadguide applied thereto; Fig. 2, an enlarged elevation of the guide; Fig. 3, a side elevas tion of the same; Figs. 4, 5 and 6, perspective views of the main parts of the guide.

Referring first to Fig. 1, A designates the main frame of a winding machine, of well known construction and B represents the traverse-frame in which the threadguide- C is mounted: The thread-guide C is arranged to reciprocate in a horizontal path back and forth along the face of the tube m on which the thread or yarn is wound, and as the cop or package is built up thereon the traverse frame B swings back to allow the guide toreoede from the.

in which t e winding is discontinued auto-.

matically upon the breakage or exhaustion of any one of the supply yarns it is practically impossible to stop the machine'instantaneously and, therefore, vthe loose end is indentations (19 g'.

-guide holder E is bent f0rliable to be wound into the package if the supply-cop is placed closely adjacent to the thread-gulde. To guard against this contingency, while at the same time economizing space, it has been found advantageous to lead the yarn over a pulley or guidewheel placed some distance above the machine.

As shown in Fig. 1, the yarn y leads from .the supply-cop (not here illustrated) to the tension-device D, placed directly above it, and thence it is drawn up over the guidewheel and then down to the thread-guide C. When abroken yarn causes the machine to stop the end of the yarn cannot reach the thread-guide before the winding spindle ceases to rotate and, therefore, the broken yarn can be easily-found, usually between the guide-wheel d and the tension-device D, and the operator is enabled to repair the break or piece-up without delay.

It will be understood that with machines arranged as above described it is necessary to provide a thread-guide having means to retain the yarn in the guide-eye to prevent its pulling out from above and the preferred structure of our device whereby we gain the advantages before mentioned will now be described in detail.

Referring to Figs. 2 and 3, designates the guide-holder which is preferably con: structed of sheet metal and adapted to be secured at its base to the reciprocating traverse-bar F, see Fig. 1. upper end of the guide-holder E is the thread-guide proper G shown in detail in Fig. 4. The guide G is preferably con- Secured to the structed of vitreous material, such as por- I celain or glass, to adapt it to resist the abrasive action of the thread which drawsthrough its eye and as here shown is formed substantially in the shape of a button. The

front face 9 of the gui e has a smooth,

-which serves asan eye for the yarn. The

opposite face of the guide G is molded with a central boss g flanked by two slots or The upper portion 6 of the threa ward from the main portion and struck-u or formed with a (circular depression e adapted to receive the boss 9 of the guide 410 Secured to the back of the guide-holder E" is a thin, metal plate J formed with an upwardly extending portion terminating in the horizontally projecting arm or prong :5, see Fig. Q. Mounted on this prong j is an auxiliary guide-member K which acts to retain the yarn from drawing up out of the guide eye g. The auxiliary guide K is also preferably constructed of porcelain or glass and is formed with a transverse hole 70 through which the prong j extends, the two members being secured together by filling the hole with cement or shellac. The guide K is also formed with a guide-eye 70 for the yarn with a contracted opening 70 leading into the eye. Preferably the plate J is formed with asmall lug or ear 9' which extends upward from the main portion of the plate and abuts the end of the prong k of the member K. The ear 1' is provided to cover the joint between the bottom of the member K and the edge of the plate J and acts to direct the yarn up into the eye is and to prevent it from catching in the crack between the guide K and plate J.

' Between the back of the guide-holder E and the plate J is secured a bifurcated, wire loop-member L which acts as a threading guide to direct the yarn into the guideeyes of the members G and K. The loopmember L is formed with substantially parallel sides 1, Z, which are bent back in the loops Z and Z ALF the sides Z, Z are bowed out to form an opening for the screw it which projects from the back of the guideholder E and extends through a hole 7' in the plate J. A nut m is screwed on to the end of the screw 7:. and binds the plate J against the member L which, in turn is clamped tightly against the guide-member E. The loop Z of the member L extends some distance above the top of the auxiliary guide K and is crooked over toward the loop Z The loop Z is bent in the form ofwa shepherds crook with a rounded top reaching just above the top of the guide K.

It will be noted that the several parts of my improved guide are all secured together by a single screw and, furthermore, the arrangement is such that the guide'G is held firmly in place against side'playl This is of utmost importancesince the friction of the guide bearing against the surface of the cop 1s liable to cause side strain as the guide is reciprocated at a high rate of speed and the present arrangement prevents it from working loose and becoming displaced. The

auxiliary. guide K preventstthe yarn from pulling-up out of the guide-notch g and the loop-member L provides for quick and easy threading of the guide as now described.

In practice the operator draws the yarn or yarns up from the tension device and secures the ends to the tube on, or, in repairing a break in the yarn the end is tied to the loose end on the package. The yarn is then led up over the guide-pulley d and the portion 3 leading to the package is drawn into the thread-guide by a single movement of one hand. The operator simply gathers the several yarns over his fingers and draws them across the rounded top of the guiding loop Z against the loop Z. The loop I deflects the yarns down back of the auxiliary guide-member K and upon reaching the bottom of the rounded rong k they will enter the opening into t e guide-eye 7c. The guiding of the yarns into the eye 7c serves also to seat them in the notch g of the guide G so that they will lead therefrom directly on to the surface of the package and consequently the coils of winding are accurately controlled during the reciprocation of the guide. 7

It will be observed that our improved guide can be threaded with ease and des-, patch without particular care or skill onthe part of the operator; and, furthermore, only one hand is required for threading it so that the other can be employed in starting the machine through manipulation of the starting lever usually provided.-

It will be obvious that various modifications might be made in the structure and arrangement of the parts of our new device without departing from the spirit or scope of the invention.
