4 Claims. (Cl. 57-59) The present invention relates to yarn spinning apparatus.

An object of the present invention is to provide a spinning apparatus for imparting a twist to yarn as the yarn is unwound from a package or bobbin and guided to either feeder rolls or to another bobbin or spool.

Another object of the present invent-ion is to provide a yarn spinning apparatus which lends itself to. rapid and ready adjustment of the speed of rotation of the flier am about the bobbinor spool for imparting the desired number of twists to the yarn as it is unwound from the bobbin or spool. i

A further object of the present invention is to provide a yarn spinning apparatus which is of simple structure, one sturdy in construction requiring little or no maintenance, one economical to manufacture and assemble,

and one which is highly effective in action.

These and other objects and advantages of the present invention will be fully apparent from the following description when taken in conjunction with the annexed drawings, in which:

Figure l is an isometric View of a portion of a twister frame head showing the spinning apparatus of the present invention installed thereon, the arrows indicating the direction of movement of the yarn;

Figure 2 is an isometric View of the spinning apparatus of the present invention apart from the twister frame head, the dotted lines indicating outlines of a bobbin or spool supported on the shaft of the apparatus;

Figure 3 is a sectional view, on an enlarged scale, taken on the line 33 of Figure 2;

Figure 4 is a sectional view taken on the line 4-4 of Figure 3; and

Figure 5 is a sectional view taken on the line 5-5 of Figure 3.

Referring in greater detail to the drawings in which like numerals indicate like parts throughout the several views, in Figure l a portion of a twister frame head is shown and is designated generally by the reference nu meral 10. The yarn spinning apparatus according to the present invention is designated by the reference numeral 12 and comprises a vertically disposed rotatable spindle 14 (Figure 3) carrying a pulley 16 adapted to embracingly receive a drive belt for imparting rotational movement to the spindle 14. A driven collar 18 projects from one face of the pulley 16 and is fixedly secured to or formed integrally with the pulley 16. A driven boss 20 projects from the face of the collar 18 remote from the aforesaid face of the pulley 16 and is fixedly secured to or formed integrally with the collar 18.

A blade or shaft 22 projects vertically from and is fixedly carried by or formed integrally with the spindle '14 and the boss 20 and forms a means of support for a bobbin or spool 24 having yarn wound thereon, such bobbin or spool 24 being circumposed about and connected to the shaft 22 by means of a cooperating keyway and key provided on the spool 24 and on the boss 20,

2,948,102 Patented Aug. 9, 1960 respectively, for effecting the movement of the bobbin or spool 24 with the shaft 22 when the latter is caused to rotate by the drive means operating in the pulley 16. The key is shown most clearly in Figures 2 and 3 and designated by the reference numeral 26.

A flier arm 28 is positioned in vertical spaced relation with respect to the spool 24 with means connecting the flier arm 28 to the bossfor rotation therearound. This means embodies an inner bearing race or member 30 carried by the boss 20 and an outer bearing race or member 32 is circumposed about and connected to the inner bearing member 30. A horizontally disposed arm 34 connects the lower end of the flier arm 28 to a ring 36 which is circumposed about and secured on the outer bearing race or member 32. A plurality of spaced ball bearings 38 are interposed between the inner bearing 1 member 30 and the outer bearing member 32 in the conventional manner and support the outer bearing member 32 on the inner bearing member 30.

Projecting outwardly from the ring 36 at a point op posite to the arm 34 is a second arm 40 with a horizontally disposed sleeve on its lower end, the sleeve being designated by the numeral 42. Within the sleeve 42 is a coil spring 44 having one end bearing against the head of an adjusting screw 46 and having the other end hearing against a cylindrical carbon braking pin 48 which is sl-idably mounted within the sleeve 42 and has the end exteriorly of the sleeve 42 frictionally engaging the exterior face of the collar 18. j The flier arm 28 is provided with means for receiving and guiding the yarn from the spool 24 to a take-up roll or spool, or other processing component, designated by the reference numeral 50 in Figure l. Specifically, this means consists in a sliding ring 52 mounted upon the flier arm 28 and a hook or eye formation 54 at the top of the flier arm 28.

The portion of the spindle 14 adjacent the lower end is housed in a spindle housing 56 having bearings 58 and 60 supporting the lower end of the spindle 14 for rotation within the housing 56. The spindle housing 56 is provided with ears 62 for securing the spindle housing to the side of the support bar 64 of the twister frame head 10, as shown in Figure l. I

Conventional means is used to removably secure the spindle 14 within the housing 56 and consists in a threaded pin 66 carried on the free end of a bracket 68 spool 24, the friction of the yarnthrough the traveling ring 52 or eye formation 54 causes the traveling arm or flier arm 28 to rotate in an orbit about the spool 24. This rotational movement of the flier arm 28 about the spool 24 twists the yarn 70 as the latter is wound upon the take-up spool 50 or conducted to another manufacturing component or process. With the end of the cylindrical carbon pin 48 bearing against the collar 18 and the spindle 14 driven by the conventional drive means, the flier arm 28 is caused to rotate at a greater speed than when drawn in the rotational path by the friction of the yarn 70. The frictional engagement of the pin 48 on the collar 18 enables the operator to effect the rotation of the flier arm 28 at a speed proportional to the rotation of the bobbin or spool 24 and to thereby impart into the yarn 70 a desired number of twists for the type of yarn being manufactured. This twisting of the yarn 70 saves one or more manufacturing steps in the production of such yarn and eliminates the necessity for transferring the yarn from the bobbin or spool 24 to a cone and then to additionalprocesses of spinning, twisting or drawing of the yarn 70. The yarn as twisted may be taken from the spool 24 and led immediately from the spool 24 to the .warp beam, winder, creeler, or any additional twisting operation without the necessity of taking 'the yarn 70 from the spool $24 to another'bobbin or-spool. .Thus, time-and money will be saved by the use of "the present invention in the manufacture of twisted yarns.

Whileonly a single embodiment of the present invention has been shown and described, other embodiments are contemplated and numerous changes and modifications may be made therein without departing from the spirit of the invention as set forth in the appended claims.
