This invention relates to textile machines and more particularly to a yarn take-off and tension means for a doubling and twisting machine.

An object of the invention is to provide a simple, inexpensive and easily adjusted'tension device and take-oi! for the over end delivery of strands of yarn to the twisting or other operating elements of a textile machine.

Another object of the invention is to provide guiding means for individual strands in a textile machine comprising loops formed at the opposite ends of awire, the central portion of the wire being bent or coiled about a. supporting post or rod to resiliently and frictionally retain the guiding means in position thereon.

And finally it is an object to provide a clamp engaging the'ends of the bent wire forming the guiding members to retain these ends at a predetermined angle to each other and also to tightly clamp the bent or coiled portion of the wire about the supporting rod.

One feature which enables the above objects to be accomplished is that the tensioning means in the form of discs may rest upon the upper part of the clamping member for the wire forming the guiding means or directly upon the wire,

the discs being oppositely disposed so that the strand may pass between them and partially about the supporting rod or preferably about a sleeve surrounding the rod, the tension applied to the strand being extremely light and being adjustable by varying the weight of the upper disc.

with the above and other objects in view the invention includesthe features of construction and operation set forth in the following specification and illustrated in the accompanying drawing.

In the accompanying drawing annexed hereto and forming a part of this specification I have shown the invention embodied in a standard form of spool support or creel for a doubling and twisting machine, but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims appended to this specification being relied upon for that purpose.

In the drawing:

Fig. 1 is a side elevation of a part of a. doubling and twisting machine showing the present invention applied thereto.

Fig. 2 is a front elevation of the parts shown in Fig. 1. v

Fig. 3 is a plan view on a reduced scale of the strand guiding and tensioning means shown in Figs. 1 and 2:

Fig.4isanenlargedviewinelevation,parts being broken away to more clearly their construction; and Fig. 5 is an elevation of the take-oi! and tensioning means as seen from the right hand side .tion which is now'deemed preferable. but it is to be understood that changes and modifications may be made within the scope of the appended claims withoutideparting from the spirit of the invention.

Briefly, and in its-preferred aspect. the inven- 1 tion may include the following principal parts: first, a substantially vertical rod or post disposed in front of each vertical row of spools from which the strands are to be delivered; second, coiled wirescloselycontactingthisrodorpostsothat they are fri'ctionally retained in any position thereon, and there being as many coiled wires as there are delivery spools; third, thread guiding loopsor eyelets at the opposite extended free ends of each of the wires; fourth, discs supported on the individual wires so that a strand being delivered from a spool may pass between the discs and partially about the vertical rod as it passes from its spool and from one guiding loop or eyelet to the opposite loop or eyelet on the 5 opposite ends of a wire; fifth, a clamping member engaging over the opposite end portions of i the coiled wires to hold these end portions at the proper or any predetermined angle to each other and to firmly tighten the coiled portion of the wires frictionally against the vertical rod or post; and sixth. afelt or other member on the upper surface of the clamping member upon which the lower disc rests.

Referring more in detail to they figures-of the drawingthere is provided a delivery spool support in the form of a frame it having spaced pins Ii outstanding therefrom upon which the spools ii are mounted. In the drawing but one vertical row of spools i2 is indicated but it will be understood that there will be a plurality of similarly supported vertical row of spools in any machine to which the invention may be applied.

Directly in front of each row of spools I2 is a supporting bar or rod II. The lower end of this bar or rod It may be attached as shown in Figs. 1 and 2 to the support Ill and the upper end similar or in' any other preferred manner attachedto the support-ll or to an intermediate member (not shown). n the rod l2 and disposed substantially in iront oi each spool I2 is a take-oi! and tensioning means presently eyelet II. The loop I4 is disposed in a position to guide a strand from a spool l2 to tension discs I1 and It on the bar I! and the eyelet ll guides the strand after passing between the discs l1 and II and as it passes to a drop wire l9.

The discs l1 and I! referred to above are rod, spaced wires having a connecting portion dished as shown most clearlyin Fig. 4 and are oppositely disposed. Their central opening is large enough to permit them to pass over the rod l2 and over a sleeve of wear resisting material, also slidable over rod l3. To place a slight drag on the discs I! and I8 so that a slight but appreciable tension will be placed on the strands the lower disc I! rests on a pad 2| of felt or other fibrous material. This pad 2! may be of ring iormand fit within the concaved portion of disc ll. The pad 2i may rest directly upon the upper end of the coiled portion of wire it but preferably and as shown in the drawing rests upon a clamp member 22 and holds the disc-i1 slightly spaced-therefrom.

Clamp member 22 tits slidably over the rod l3 and forms a small platform for the pad 2|. This portion of the clamping member is plane and is disposed substantially horizontally and maintains the discs I! and It in their proper relative positions to their sleeve 20. From this central portion of the member 22 extend two downwardly extending clamping arms 22 and 24. Arm 2! clamps around the end of wire it upon which eyelet I5 is secured and arm 24 extends around or clamps the arm provided with the loop i4. As the arms 22 and 24 are integral with the central portion of the clamping member 22 the angle between the arms of wire l6 carryingthe guiding members l4 and I5 can becontrolled so that the guiding loop I4 and the eyelet I! can be positioned at any proper relative angles to each other for the particular disposition and guiding of the strands called for by the machine on which they are mounted.

In addition to positioning the guide carrying arms of wire it at their proper angles the clamp 22 serves to bind the coils of the wire i6 more tightly against the rod II to firmly hold the complete assembly irictionally thereon. To change the position of the assembly up or down on the rod it it is only necessary to release the clamp arms 23 and 24 of member 22 from the ends of wire I6, separate these ends slightly manually to slightly enlarge the opening within the coiled portion, and then slide the coil I6 to the desired vertical position. After the clamp 22 .is replaced in position the coil I will again firmly and resiliently engage the rod I2.

coiled about and irictionally engaging said rod to support said wires in adjusted positions thereon, strand guiding means at the opposite extended ends of said wires, and tensioning means for said strands supported in position by said coiled wires.
