2 Claims. ,(Cl. 242--157 T,his invention relates to guidesv and provides for a new and improved Vguide support as well asa new and improved guide.

The guides to which this invention relates are o-I the type employed generally in the winding of lamentary or strandular' material such as, for example, various textile materials, threads, yarns, cords, wires, etc, For Aconvenience in thev further description of this invention, referencey will be made toy a textile apparatus such as a yarn winding and twisting machine, although itis understood that the invention is also applicable to other types of machinery where guides are employed'. M

In textile yarn winding and twisting apparatuses,a `yarn or thread is pulledoff a supply package and passed through a yarnv guidewhich lays it'on a take-up package. `Guides employed in such winding and twisting apparatuses are usually made-fromY relatively brittle and'fragile materials, such as for example, porcelain, lava, etc. Consequentlya great deal of care mustA be taken mounting and securing them tothe reciprocating traverse bar whichv is part'of the winding and twisting apparatus. l If the guides areV tightened too excessively, the vadditional pressure may cause them tocrack or break. Also, if the guides are not securely fastened tothe traverse bar their proper functioning may be impaired.

An evenly wound package is formed. by pass ing'theyarn or thread througha securely mounted guide on the traverse bar. Since -a traversing motion is employed to form the wound package, such a motion will impart a substantial tension to the yarn. Further, if the yarn is being twisted, an additional tension is placed on it because ofthe ballooning action as it leaves the supply package. Lateral motion of a traverse bar also tends to vary the tension in the yarn, the tension becoming greater as the guide is moved farther from` a central or normal position above the yarn supply. Repeated lateral travel of the guide plus tensions resulting from the pull of the yarn, iirst from one direction then from an opposite direction will tend to loosen the guide. Should the guide Vbe of a type incapable of withstanding such opposite and repeated pulling it will loosen, and its function will be de strayed, the result being a poorly Wound package. Further, a loosening ofthe guide on such an apparatus is hastened because of vibrationv of the apparatus itself.

Because these yarns or cords are generallyl heavier than textile yarns, the tensions in them will be increased during the twisting and winding operations. The additional tensions thus encountered, coupled with the tension created by the motion of the guide and the traverse bar, places an added strain on the guide, whichwill more readily tend to loosen it, and consequently sov impair its function.

To overcome these and other difliculties' en countered with the use of such guides, thisrinvention advantageously provides for. a yarn guide support which is adapted to substantially permanently position ayarn guide on atraverse bar;v The construction of the guide supportisy simple;` it is adapted to withstand' torsional pull from any direction and it will resist loosening by vibra tion. The yarn guidef supporting member is advantageously constructed to conform to the contour of a traverse bar. Its form is such so as to substantially embrace the traverse bar in a clasping manner making it substantially self-surt porting. Wherel it is desirable to use al guide n separate from the support, the guide can be securely positioned in a support havingthe aforesaid attributes.

Thisinvention will be more fully described by reference to the accompanying draai/ing*l in which: f

Figure 4 is an isometric rear view of a modication of the yarn guide support;

Figure is an isometric rear view of a yarn guide integrated in the yarn guide support.

In Figure l of the drawing, is shown a section of a yarn winding and twisting apparatus l0 employing at each winding andtwisting Aposition two parallel spindles I4 having'mounted thereon supply packages or bobbins I3 carrying yarns I2 which are to be twisted. InA order `to produce rotation of the spindles It` to form a twist in the yarn I2 as it leaves thesupply package I3 the spindles I4 are driven by'means of the driving drum I6 through a belt I5.

I The yarns'I2 are twisted 'as they are being' pulled oft the rotating supplypackages I3` and passed through kflyers vII'I: positioned above the.

supply packages I3 on spindles I4. On leaving the yers I1 the yarns I2 next pass through pigtail guides I9 and then are gathered by the traverse guide 20 which is mounted on the traverse bar 2l. The traverse guide 20 thereafter lays the yarn in an orderly manner on a yarn collecting spool or bobbin 22 that is surface driven by the take-up roll 23.

Referring to Figure 2 of the drawing, there is shown a traverse guide 20 mounted on a substantially rectangular traverse bar 2l. The traverse guide 20, as shown, incorporates a yarn guide 25 and a yarn guide support 21 mounted on the traverse bar ZI and it is secured to the bar ZI by the bolt 29. The support 21 is constructed so that it tends to embrace the periphery of the traverse bar 2| and substantially supports itself thereon. The elements 33, 34, and 35 of the body 32 of support 21 extend along and about the periphery of the traverse bar 2| to prevent lateral and circular displacement as wellas displacement in a perpendicular plane to the traverse bar.

. As shown, a substantially rectangularly constructed guide 25 is held by the support 21. The support 21 can be modified to provide a support for the guide 25 should it havea form othei` than that shown. In Figure 2, the guide 25 is held between a pair of spaced arms or projections 39 extending outwardly from the support. These arms are spaced slightly less than the width of the guide in order that a firm hold of the guide can be had. The arms 39 are supported at their sidesk by the tapering sections 38 attached to the laterally extending elements 33.

The guide 25 is additionally fixed in position bya bolt 29 extending through a slot 26 in the yarn guide 25, through the traverse bar 2|, and then through a slot 36 in the yarn guide support 21. The guide 25 is thus, advantageously, held by the arms 39 at its upper portion and by the bolt 29 at its lower portion.` The mounted guide 25 will thus resist displacement in` any direction. n

Figure 3 further illustrates the construction of the yarn guide of Figure 2 as seen from the back. lThe yarn guide support 21 comprises a main body 32 having laterally extending arms 33, an intermediate portion 34 and a lower extension 35. The support'contour conforms vto the shape of the traverse bar 2I so that the laterally extending arms 33 and lower portion 35 arenadapted to embrace the traverse bar periphery in a clasping manner. The laterally extending arms 33 serve not only to prevent displacement of the guide support but also to carry the outwardly projecting guide aligning, supporting, and protecting members 38. An additional vertical support is provided for the guide by means of arms 39 projecting from members 33. Lateral adjustment for the guide support 21 is also provided by the elongated slot 36 in the intermediate portion 34.

Illustrated in Figure 4 is Ia further modiiication of the support 21 whose frictionally bearip g portions 32 are arcuate to conform with the periphery of ya round traverse bar. Advantageousfly the support extends at least 180 degrees Qrmore about the periphery of the traverse bar tothereby` enable the guide support to clasp the bar. and ,substantially frictionally support itself thereon. In this .modification of the support, the arcuate-mainbody portion 32 comprises a laterally extending element 3 3 and an intermediateportion; '4 I. ,..Lateral` adjustment `of the` yarn guide support 21 is provided by the elongated slot 36 in the peripherygof the intermediate arcuate portion 4I.

A further modification of the support 21, which can be mounted either from the bottom or the top of the traverse bar, is illustrated in Figure 5. The main body 43 comprises a laterally extending body portion 44, an upwardly extending portion 45, and a pair of upwardly extending guide aligning and embracing elements 41, having outwardly projecting therefrom guide clasping members 48. The form of the body 43 is such so that portion 45 and sections 41 substantially embrace the traverse bar 2| to frictionally support itself thereon. Lateral adjustment for the yarn guide support 21 is provided by the slot 46 in the portion 45.

Figure 6 shows another modication in which the yarn guide is integrated into the support and Where such supportiis mounted on the front of the traverse bar. The yarn guiding element 55 is advantageously made of the same material as the support 50 and it is advantageously plated with a wear-resisting metal. The support 50 comprises a body portion 5I having a pair of laterally extending elements 52, an intermediate portion 53, and a lower portion 54. The upwardly extending element 55 of body portion 5I extends above the traverse bar so that a guide 56 can be formed therein. The guide 56 may be formed by bending and forming a portion of the top edge of the element 55 to a desired contour. Lateral alignment of the yarn guide and support 50 is obtained through slot 51 in the intermediate body portion 53.

Reference to yarn in the specication and claims is intended to include generally any iilamentous or strandular material which is subjected to a winding operation or a 'winding and twisting operation. Although the foregoing description of the invention has reference to the use of a yarn guide support in connection with a yarn winding vand twisting apparatus, the invention advantageously can be used in other types of winding apparatus. Further, it is to be understood that the yarn guide support may be i modified in various ways Without departing from the spirit of this invention.
