Application filed February 2, 1923; Serial No. 616,572.

To aZZ whom it may concern:

Be it known that I, LLoYn H. LIIIPS, a

citizen of the United States, residing atv Bethlehem, in the county of Lehigh and State of Pennsylvania, have invented-certain new and useful Improvements in Apparatus for Spinning, of which the following is a come so caught breakage of the yarn is a very likely consequence. This makes it im possible to put a high twist in the yarn without the process being'made to proceed very slowly so slowly that in fact there willbe greater production if the spinning is performed in two operations (which is now the accepted and usual practice), the

first so that the yarn gets a low twist, i. e., suflicient to bind the threads together and close or lay the fibres on them, and the second to put in the high twist. The object of this invention is to put in the yarn a' high twist in a single high-speed operation, thus to considerably increase production. This I have found is possible by using the means hereinafter set forth and finally embodied in the appended claims.

In the accompanying drawing,

Fig. 1 is a front elevation of the delivery package, with its supporting and rotating means, the receiving spool and its supporting and rotating means, the thread traversing means and a flier embodying the invention;

Fig. 2 is a front elevation of the flier on a larger scale; and

Fig. 3 is a plan of the flier. v

a designates the delivery windings of yarn on a spool 79 which is carried and rotated in the usual manner by a vertical spindle a suitably driven at the requisite speed. (Z is the receiving spool having its axis horizontal and its trunnions e or equivalent guided in the brackets f, 9 being a driving wheel on which the spool rests and by which it is driven. h is a traverse rail reciprocating horizontally and having a guide 72/ for the yarn, and z is a fixed yarn guide substantially in vertical alinement with the spindle. All these parts are well known and in common use.

In the following description of the im' proved flier it will be understood that all the details specified are not indispensable: The body of the flier includes, in the illustrated example, a cylindrical metal shell j and a core j of wood or other lighter material, the object of this construction being to provide a hard peripheral surface on the body without unduly increasing its weight. The body has an axial hole whereby it may be slipped over the spindle c. There are two light somewhat elastic wire armsZ I and m, respectively bent to formeyelets Z and m. Arm Z extends horizontally from the top of the body 3' and arm 012.. extends.

first straight from the bottom of'body a and then is bent downward at right angles. They are secured to thebody both in the same way, to wit, as by grooving the end (upper or lower face of the body as the case may be) inward from its periphery, providing a hole in the body at the inner end of the groove, and then having bent down the inner end of the arm fitting'the arm to this groove and hole, as shown in Figs. 2 and 3. Arm Z is shorter and represents less mass than arm m and so to counterbalance the latter a weight n maybe embedded in the body 0. The eyelet Z stands in a horizontal plane, and eyelet m in a vertical plane. The extent of 'the downwardly bent free end of arm m is suchthat when in rotation the flier rises (in a manner usual with fliers that are free on the spindle, as in the present case) as an incident of the draft of the yarn thereon there will be clearance betweefrthe latter and the upper flange of the spool I) even when the uppermost windings a are delivering. The arm Zprojects but a short distance from body j, i. e., only. sufficiently far so that there will be set up no appreciable ballooning of the yarn between Z and i as an incident of the rotation of the flier.

the body. This is not indispensable, but it is probably the best way to provide the contact because it will continue effective and also result in an equable amount of friction This contact in being produced whatever angularity the stretch A of yarn assumes with reference to the stretch A between Z and i on account of the arm in practice springing outward or tending to straighten as shown in dotted lines in Fig. 2 due to the action of centrifugal force.

In short, my invention contemplates providing a surface for contact of the yarn therewith so that by such contact and at the point thereof the twist put in the yarn will be checked in working downward from the" take-up means (d) toward the delivery package (a) before it approximates and would thus catch the fibres of the windings of the package. Each guide of an ordinary flier at present tends to, though it does not actually, accomplish this purpose since the extent of contact is neither suflicient (and cannot be made so without unduly weighting the guidelnor is it steady enough. Wherefore my invention further contemplates affording this contact by means against which the yarn is held stretched between the two guides, and when this last condition exists it will be found that the spinning of yarn with a high twist can be performed in a single operation and with very materially increased production over known methods.

It is preferred that the guides maintain the stretched part A of the yarn at an angle acute to the plane in which each guide rotates, rather than at an angle acute to the axis of rotation, whereby wiping of the yarn on the said contact means occurs rather lengthwise than transversely of the yarn.

Itwill be understood that while the spool,

(Z is rotated from the wheel 9 to take up the spun yarn the spool a is by spindle 0 rotated clockwise as viewed in plan to put in the twist and that the flier is rotated in the same direction as the spool 0;, all as usual. When the normal speed is reached the flier will have risen under the draft of the yarn to about the dotted line position indicated in Fig. 1. p

Havingthus fully described my invention, what I claim as new and desire to secure by Letters-Patent is 1. A yarn spinning organism including, with means to take up the spun yarn and means coactive therewith to spin the yarn including awound package and means to ro tatethe same around the axis of itsf'windings, a pair of spaced guides freely rotative as a unit'on said axis and through which the yarn successively extends from the package to the take-up means, and means, in con- 7 2.
