(or. 117-49) when l3. Fixedly secured to the-upper portion of whorl I3 is a lowerflier H which comprises i This: invention relates to a combined twister and packaging machine whereby the fliers impart two turns per revolution to the yarn being wound thereon, and is so designed as to stand in a vertical position and therefore being capable of being mounted on a conventional twisting fram roving frame and the like by the simple addition of atop bolster rail.

-;It-is an object of this invention to provide a acombined twisting and packaging machine for yarns wherein the yarn can be passedfrom the draftingv rolls in fiber preparation machinery twice as fast as in a twisting machine employing ring twisting because ringfltwisting imparts only one turn or twist perxrevolution whereas the present invention imparts two turns per revolution to the yarn being not only twisted, butpackaged at the same operation. It is another object of this invention to provide anapparatus adapted to be associated with,

fiber preparation machinery which will-wind and twist the yarn in one. operation and which is applicable to roving frames, spinning frames,

twisting frames and the like, the spoolinglopera tion'being eliminated as the yarn is twisted and placed on proper yarn holders such as tubes, spools and thelike, at the apparatus is applicable to roving frames, spinning frames, twisting frames and the. like, since ittakes the yarn directly from the drafting" rolls of thesefrarnesrand twists the same and packages it at oneoperation.

Some of the objects of the been stated, other objects will appear as the description proceeds-when taken in connection with 'the accompanying drawings, in which:-

Referring more specifically to the drawings,-

the numeral Ill denotes the lower rail of a twister which has mounted therein a flanged bolster II, this bolster being secured to the rail- ID by any suitable means such as nut l2 disposed beneath the rail. Bolster H has rotatably' mounted therein a spindle which l spindle has secured on the upper end thereof a the same operation, and

invention having member H and a counter weight member l6. Member l5 extends upwardly and is forked at its upper end. 1 i

Secured as at ll to one of the forked members is a flexible member I8 jwhich is composed of any flexible material such as rubber tubing and the like and secured to the upper end of member l8 as at I9 is arm 20 ofthe upper flier 2|, said upper flier 2| having a counter weight arm 22 integral therewith disposed on the opposite side of the V pivot point from member 20. y The upper flier 2| has a spindle which is rotatablymounted in bearing 29 which bearing is secured in top rail 30. Fixedly secur'edonthe upper, end of spindle 28 is another whorl 3| which is adapted to be driven by the same cylinder that drives the lower whorl l3. i

.Thellower portion of flier M has projecting up- ,spool rack remains stationary.

End thrust bearing 34 assumes the weight'of the spool rack as the flier l4 rotates;: Spool rack 35 has two arms 36 and 31 which extend upward- 1y and'thenagain laterally and are joinedtogether again at the hub portion 38. Fixedly se cured in. hub 38, by any. suitable means such as set screw isa vertically disposed rod 39, The

upper end of member39 is forked and has two projections 4| and 42 which are adapted to fit into cavities 43 and 44 respectively of locking device 45. -Member 45 has integral ther ewith an upwardly projecting member 46 which is adapted to fit into the central'portion of spindle 28. By

referring to Figural it is seen that the spindles in bolster H and *themember 39 are in direct alinement whereas, the spindle 28 which is rotatably mounted in the top rail isoff-center Since the spool rack remains stationary at all times, and the fliers l4 and 2| are constantly rotating, the resilient member I8 must be provided because the fliers l4 and 2| rotate about two different centers, in other words, the two fliers are not concentric. I 7

By placing the upper spindle 28 off-center from the lower spindle, and providing locking member 39 with prongs 4| and 42 thereon which fit into the second locking member 45, it is impossible for the spool rack 35 to rotate and it is thereby held in stationary position at all times, regardless of the speed of the fliers l4 and 2|.

The upper end of member l5 has a prong 53 which extends upwardly and laterally and has integral with the end thereof a collar 54, said 001- wardly from the central portion thereof, a collar lar 54 being adapted to rotate around the lower spiral gear 55 cut therein which is adapted to mesh with a pinion 56, said pinion 56 being fixedly secured on shaft 51. The shaft 51- has one end rotatably mounted in housing 58 and its other end rotatably mounted in the cover 59 which is secured to housing 58 by any suitable means such as screws 60. Pinion 56 also meshes with another pinion 6| which, in turn, is fixedly secured on shaft 62, said shaft 62 being also rotatably mounted in housing 58 and cover 59. A beveled gear 63 is fixedly secured on=shaft 62 wh=ich meshes with a second beveled gear 64 fixedly secured on shaft 65, said shaft 65 being rotatably mounted in a: bearing- 66 which is integral with the housing 58' and' another bearing 68 which is integral with the upper portion of spool rack 35'. The housing 58 encloses the gears- 55', 56, GI, 63 and 64 and normally rests on the top of spool rack 35 and isse'cure'd thereto: by any suitable means'such as stud bolts 69% Fixedly mounted on the end of shaft 55 is a worm gear 16' which meshes with apinion I'I'. Pinion 'ITis fixedly mounted on the upper end of shaft II? which shaft is rotatably' mounted in bearings 1'9and80 which are" integral with member 3t? of spool rack 35.

The lower end of shaft [8 has fixedly secured thereon a beveled gear 8*I which meshes with" another beveled gear 82 said beveled gear 8'2 being fixedly secured on one end of roller 83. 'Roller 83 has its ends rotatably mounted in members 36- and 3'! of spool rack 38, and a tube of yard 8d- 35 normally contacts this roller. andiis rotated there'- by. The tube' of yarn is rotatably' mounted on a transverse shaft 85- which is sl-idably mounted in slots 86 and 81' cut in vertically disposed members 36 and 31 respectively. These slots are identical' in all respects and a showing of one is deemed sufficient. (See Fig. 2

One end of shaft 85' has a tension spring 88' se'-r cured thereto whichextends' downwardly and is secured to member 35 as at 89; The other end of shaft 85*hasa similar spring 99 secured thereto which also extends downwardly and: is secured as at 91 to'vertically'disposedmember 37. It is seen: that these springs normally pull the shaft 85' and the tube of yarn 84, which is rotatably mounted therein, downwardly incont'act' with the roller 83 at all timesand as the roller rotated the tube of yarn to cause the yarn to uniform rate; v

Beveled: gear 82 also meshes with another beveled gear 92" which is fixedly secured on the shaft 93,- this shaft 93' is rotatably mounted in bearings 84 will also be rotated be wound on the spool at a 94' and 95 which are integral with the vertically disposed member 36: I

Fixedly secured on the lower end of shaft 93 is a beveled gear 96 which meshes with a beveled gear 91, said beveled gear 9'! being fixedly'mounted-on one end of traverse 98. Traverse 98 has its ends rotatably mounted in members 36 and 31, and has a suitable reversed groove cut therein which is engaged by one end of traverse 99. Traverse 99 is slidably mounted on bar I09, which bar has itsends secured also in vertically disposed members 36 and 3'1. Rotatably mounted 'intheleft-hand end of traverse 99"; (Fig. 4),

is a plunger I'BI: which has a flattened lower end fitting into the groove in traverse 98 and since this member I I' has a flattened portion engaging the groove when it comes to'one' end of the reverse groove, the member is free to' rotate and to start the traverse travelling in the opposite direction on the rod M8. The right-hand portion of traverse 99, as seen in Figure 4, has pivotally mounted therein a thread guide I62 which projects upwardly and has an eyelet I93 in the upper end thereof through which the strand passes to the spool of yarn 94. A bar I04 supports the member I92 and prevents the clockwise rotation of thread guide. 99 about the rod I90 and likewise has its ends fixedly secured in members 36 and 31.

It is seen in Figure 1 that as the traverse 98 is rotated that the thread guide I02 will be travversed back and forth due to the reverse groove in the traverse 98, and cause the yarn to be wound properly upon the" spool of yarn 84 A strand of yarn I05'is fed to the apparatus through the bore its in the spindle 28'.

From the spindle 28 the yarn passes through eyelets I97 which are mounted on fliers II and I4 and then goes into another bore H18 in the lower side of flier I4. From this bore the yarn passes through a vertically disposed bore me in the lower portion of spool rack 35 and upwardly to another eyelet I I0 secured were thread guide I92. From this point the yarn goes- 'through the eyelet. we in the upper end of the thread guide I92 and'onto the cone of yarn 84 For each revolution of fliers I4 and 24 the yarn I95 is given two turns twist.- The first twist is given as the yarn leaves the drafting rollers to" enter bore it and the second twist is' given be-- tween bore I99 and eyelet I93; Since this appa' ratus provides two turn twist per revolution of the flier, the production is doubled because" the" yarn can be passed from the drafting rolls twice as fast in the process of ring twisting where one turn twist is given per revolution of the ring traveler.

As the fliers I4 and 2I are rotated. the collar 54 and worm gear 55 are likewise rotated, thereby .rotating the pinions 56 and 6| and the beveled gears 63 and 64. This will cause the shaft 65 with the worm gear I6 on the end thereof to likewise rotate which will, in turn, rotate the shaft 78, the'bevel'ed gears BI and 78-2 to caus'ethe roller 83 to rotate the tube of yarn 8'4 and to draw the thread thereon.

In themeantime, the beveled gear 92 will ro tate the shaft 93 and cause beveled gears 96 and 97 to rotate traverse 98 and traverse the thread guide 96 to properly place the yarn on the tube. It is thus seen that means have been provided whereby the spool rack 35' can be held stationary at all times as the flier frames I4 and- 2t rotate at a very high speed.

This is done by placing the top spindle on adifferent center from the bottom spindle and providing the locking device shown in Figures 4 and 5-. This construction also allows the spool rack and spindles to be operated in a vertical position instead of a horizontal position. When mounted in a horizontal position the spool rack has hereto-- fore been held in stationary position by means of weights or gravity, which is not satisfactory due to varying frictional forces in the bearings.

Since my apparatus winds and: twists the yarn in one operation and is applicable to roving, spinning and twisting frames, the spooling operation is eliminated. The apparatus is applicable to roving, spinning and twisting frames since it of these frames.
