My invention relates to twisting or spinning machines, and has particular reference to a yarn guiding device for use upon such machines, and adapted for other uses.

An important object of the invention is to provide a yarn guiding device for use on a twist ing machine which will eliminate the conventional flyer. v

A further object of the invention is to provide a device of the above mentioned character.

which may be used to eliminate the conventional traveler on a spinning or twisting machine.

A further object of the invention is to provide a device of the above mentioned character which is adjustable to obtain'the selected tension on the yarn.

A further object of the invention is to provide a device of the above mentioned character wherein an annular floating member engages with the yarn, taking the place ofthe usual flyer or traveler.

A further object of the invention is to provide a device of the above mentioned character re-v quiring no lubrication when in use, thus eliminating the disadvantage of the 011 being applied to the yarn.

Other objects and advantages of the invention will be apparent during the course of the fol- I lowing description.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 155 designates a vertical rotary spindle of a twisting machine, driven by any suitable means. This spindle carries the spool l6 vof yarn. The spindle i5 is mounted upon the spindle swing H, and a vertical post it is rigidly mounted upon the spindle swing, adjacent to each spool IE.

The numeral I8 designates a yarn guiding device as a whole, arranged adjacent to the'top end of each spool t6, and the top end of the spool projects into this *yarn guiding device for a short distance. This yarn guiding device takes the place of theconventional fiyer. The yarn guiding device comprises a yarn guiding ring 20, which is stationary in use. This yarn guiding ring is closed or free from any slit and is preferably formed of steel but may be made of any other suitable material, and is preferably polished so that the yarn will slide freely thereon. The device 19 further comprises a floating annular member or casing it, including comwhich are identical. The annular sections comprise outer opposed annular jaws 23, having their outer edges separate and spaced, as shown. These outer edges are preferably flared, as shown. These jaws are preferably formed of steel or any other suitable material, and the outer edges of the jaws are preferably polished.

. The jaws 23 have openings 28' formed therein so that the yarn maybe conveniently passed aboutthe yarn guiding ring 20. Preferably formed integral with the annular Jaws 23 at Figure 5 is an enlarged transverse section their inner edges are horizontal annular webs 2t, carrying opposed jaws 25 at their inner edges. The annular horizontal webs 2d are connected by pins 25', passing through openings 26 formed therein. Each pin is screw threaded at its opposite ends for receiving nuts 21. carries washers 28, disposed inwardly ofthe webs 2t and having reduced extensions 29, to enter a compressible coil spring 30. The reduced extensions retain thecoil spring spaced from the Pin 25. The springs 30 tend to spread the horizontal 'webs 24, and these webs are drawn together by manipulating the nuts 21, as is obvi-,

Each pin 25" ous. The jaws 25 receive between them an in- .ner connecting ring 3| and the jaws 25 clamp against the connecting ring 3|. The outer jaws 23 are curved in vertical cross section and are substantially concentric with the face of the yarn guiding ring 20, which is circular in cross section, but the jaws 23 are formed on a larger radius than the yarn guiding ring 20, affording a space between the jaws 23 and yarn guiding ring 26. The yarn i6 is passed over the outer edges of the jaws 23 and upon the inner side of the yarn guiding ring 20. By manipulating the nuts 21, the jaws 23 may be brought together, thus reducing the space between these jaws and the yarn engaging ring 26 and thereby regulatf ing'the tension of the yarn, by increasing the area of contact between the yarn and the yarn guiding ring 20. This adjustment also compensates for yarns of different thickness.

Rigidly connected with the yarn guiding ring is a radially extending rod 32. This rod is 4 arranged adjacent to one end of a sleeve 33,

33 near its forward end. The pin 36 has a transverse slot 42 in its screw threaded end and the rod 32' extends through this transverse slot. The sleeve 33 is rigidly mounted upon a coupling 43, in turn rigidly mounted upon the vertical post i8. By adjusting the nut 39, the tension of the spring 40 maybe regulated and the pin 36 and associated elements'form a pivot for the rod 32, whereby the rod 32 may be swung to the horizontal or vertical position and held in such position against accidental displacement.

The operation of the device is as follows. The yarn guiding device I9 is positioned adjacent to the upper end of the spool, so that the top of the spool passes into the same. The yarn guiding ring 26 is horizontally arranged and the annularmember or casing 22 is also horizontal. The yarn I6 is passed over the outer edges of the jaws 23 and about the inner side of the yarn guiding ring 20, and passes above the spool l6, to be rewound upon another spool. Due to the rotation of the spool l6, the yarn slidably engaging the yarn guiding ring 26 will freely travel around the'station'ary yarn guiding ring and will also. travel circumferentially about the casing or annular member 23. This casing or annular member floats in operation. The yarn guiding device may beused in a twisting machine to remove theyam from the spoolor to apply the yarn to'the spool. The yarn guiding device may be used in connection with spools, bobbins, quills, spindles or other devices.

In Figures 6-12 inclusive, I have shown a second form of yarn guiding device embodying my invention. In these figures, the numeral 44- designates a stationary annular member or casing including upper and lower annular sections 45.

These sections include inner opposed jaws 46, which are curved in vertical cross section. The

free edges of these jaws are preferably flared.

These jaws are preferably formed or steel, but

, may be formed of any suitable material, and the horizontal annular webs 41, preferably formed integral therewith. At the outer edges of the horizontal webs '41 are opposed jaws 48, preferably integral therewith, and curved in vertical cross section. The horizontal webs 41 are adjustably connected by the pins 25', described in connection with the first form of the invention, and the same springs 36 are employed. By manipulating the nuts 21, the webs 41 may be drawn together and the outer jaws 48 clamped to a connecting ring 49, having an opening 50 formed therein. The rod 32 is rigidly connected with the connecting ring 49 and engages the same pin 36, described in connection with the first form of the invention. The rod 32 is therefore adapted to be swung to horizontal and vertical positionsand to be held in such positions against displacement.

Arranged between the jaws 461s a floating yarn guiding 'ring 5|, which is preferably formed of steel but may be formed of any suitable material,

I and the ring 5| is polished so that the yarn will not have undue frictional engagement therewith. This ring 5| is continuous and free from any slit. The jaws 46 are curved in'vertical cross section and the floating ring 5| is circular in vertical cross section, and the jaws 45 are formed upon a larger radius than the ring 5|, thereby affording a space between these jaws and the ring 5| for the passage of the yarn. The yarn i6 from the spool is passed'about the inner edges of the jaws 46 and about the outer side of the floating yarn guiding ring 5| and then extends above the yarn guiding device to be wound upon the next spool. The floating ring 4| may be formed solid, as shown in Figure 5, or I may employ a hollow floating ring 5|, Figure 5 When a hollow floating ring is employed, the

inner side is preferably cut away to render the same light. In this form of the invention, the

yarn engaging ring 5| floats, .while the outer annular member or casing 45 is stationary.

The outer annular member or casing 46 may not be provided with the openings 23, to facilitate threading the yarn about the yarn engaging ring 5|. For this reason, the casing 46 may have a transverse diagonal slit 52, so that the .yam may be threaded through this slit about the outer side of the floating ring 5| and brought into engagement with the inner edges of the jaws 46. v The pull upon the yarn when being wound upon the spool above the yarn guiding device is radially inwardly and there will be little tendency for the yarn to reenter the slit 52. However, the inclination of the slit 52 with respect to the rotation of the yarn will, prevent the yarn re-entering the slit, and this relative inclination is maintained by'inverting the yarn guiding device, for the right or lefttwist upon the yarn.

In Figurev 8, the edges of the slit 52 are arranged in connection with the first formpof the inven- .tion, the slit 52 may be omitted.

The operation of thesecond form of the invention is as follows.

The yarn I6 is passed about the inner edges of' the jaws 45 and about the outer side of the floating ring 5| and extends to the spool above the guide device, upon which the yarn is wound.

The yarn guiding ring floats and the yarn travels freely circumferentially of this floating ring 5 i By adjusting the nuts 21, the jaws 46 may be drawn together and, the tension increased upon the yarn, by increasing the areaoi contact between theyarn and the floating ring.

While I have shown my yarn engaging device as used in connection with a winding machine for dispensing with the conventional flyer, yet it is obvious that it may be used in connection with a spinning frame for dispensing with the conventional traveler. The device is not restricted in use in connection with a twisting machine or a spinning frame, but may be used in various other places wherein it is desired to guide yarn.

Asis well known, some yarn is twisted right, while others are twisted left, and my yarn guiding device takes care of this situation, as it may be readily inverted. The device is inverted by slightly loosening the nut 38 and turning the shaft 32 upon its axis. 7

The guiding device is adapted to handle all kinds of yarn, such-as cotton rayon, silk, wool, etc.

The yarn guidin jaws may face horizontally inwardly or outwardly, upwardly or downwardly.

It is to be understood that the forms or my invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
