10 Claims. (Cl. 19-159) This invention relates to a coiler mechanism and has particular relation to a coiler mechanism wherein a sliver of material is coiled into a rotatably mounted sliver can.

According to the present invention an improved turntable arrangement for a coiler mechanism is provided wherein a sliver can is rotatably mounted beneath a coiler head to receive a sliver therefrom which is coiled symmetrically within the can. In the present invention the sliver can is mounted on a turntable which is rotated by means of a novel driving arrangement. The present invention contemplates improved driving means forA the turntable whereby the latter can be adjusted in a horizontal direction relative to the coiler head in order to permit various sized sliver cans to be properly positioned with respect to the coiler head. The turntable drive includes also improved means for permitting a reversal in t-he direction of rotation of the turntable.

The improved drive means for the turntable includes a worm shaft which meshes with a worm gear secured to the turntable. The worm gear and turntable are rotatably supported by a bearing assembly which is adjustably secured to a base assembly. The bearing assembly together with the turntable may be adjusted to selected positions spaced in a direction parallel to the worm shaft.`

An object of the invention is to provide a coiler mechanism having a rotatable turntable for supporting a sliver can beneath a coiler head with improved driving means for rotating the turntable.

Another object of the invention is to provide a coiler mechanism including a rotatable turntable for supporting a sliver can beneath a coiler head with improved driving means for the turntable providing for adjusting the turntable in a horizontal direction relative to the coiler head to enable different diameter cans to be used and which will be correctly positioned relative to the coiler head.

It is a further object of the invention to provide a mechanism as defined in the preceding object wherein the driving means includes a novel arrangement for permitting a reversal in the direction of rotation of the turntable.

Other objects of the invention will become apparent from the following description taken in conjunction with the accompanying drawings forming part of this specification, in which Fig. 1 is a view in elevtion of a coiler mechanism embodying the teachings of the present invention;

Fig. 2 is a view taken along the line 2-2 of Fig. 3 with parts shown in section illustrating the driving mechanism for'rotating the turntable;

Fig. 3 is a partly sectional and plan view taken along the line 3-3 of Fig. 2 with certain parts broken away;

Fig. 4 is a view in section taken along the line 4-4 of Fig. 3; and

Fig. 5 is an elevational sectional view showing the idler shaft and gear forming a part of the driving mechanism.

Referring now to the drawings, there is illustrated in Fig. 1 a coiler mechanism for coiling a sliver of fibrous maare iiiatt rjce terial into a sliver can in a symmetrical manner so that the coiled material may readily be withdrawn from the can. The coiler mechanism includes a coiler head 1 which may be of conventional construction and which is supported at the upper end of a vertically extending hollow column 2, secured at its lower end to a base 3. The base 3 is adapted to rest upon a supporting surface such as a floor. The coiler mechanism also includes a turntable 4 which is arranged to support a sliver can 5 illustrated in Fig. 1 as extending upwardly from the turntable with its open end directly beneath the head 1. The turntable 4 is rotatably supported by the base 3 in a manner presently to be described.

The turntable 4 is rotated from a transmission yarrangement which is driven from an input shaft 6 shown in Fig. 2 as extending horizontally into the hollow of the column 2. The input shaft 6 is conventionally driven through a drive D from a carding or other textile machine with which'the coiler is being used. As illustrated in Fig. 2, the shaft 6 drives a transmission 7 within the hollow of the column which is drivingly connected to suitable gearing Salso within the column which in turn is operatively connected to the turntable so that the turntable is rotated in response to rotation of the shaft 6. The shaft 6 is also effective when rotated to effect rotation of a vertically extending shaft 9 which is drivingly connected to mechanism (not shown) in the coiler head 1. Inasmuch as the coiler head forms no part of the present invention the details of construction thereof will not be described.

The transmission 7 includes a bevel gear 10 secured to the shaft 9 which meshes with a gear carried by the shaft 6. The shaft 9 is journalled by spaced bearings 11 carried by an extension 12 projecting horizontally from the inner wall of the column 2. A gear 13 is fixed to the shaft 9 in meshing engagement with a gear 14 secured to a shaft 15 which is journalled by spaced bearings 16 supported by thel extension 12. The transmission 7 is drivingly connected to the gearing arrangement S by means of a drive shaft 17 which is located within the column 2.

In the present invention the drive shaft 17 is connected between the transmission 7 and the gearing arrangement 8 by means of

universal joints

18 and 19 which permit adjustment of the shaft 17 for a purpose appearing hereinafter. The joint 18 includes an extension 20 detachably secured to the lower end of the shaft 15 as viewed in Fig. 2, as by a press fit. The extension 20 projects into a recess formed in a fixture 21 attached to the upper end of the shaft 17. A pivotal connection is provided between the extension 20 and the fixture 21 so that the shaft 17 may be pivoted about a horizontal axis relative to the shaft 15. A similar connection is provided between the shaft 17 and the gear arrangement 8. As shown in Fig. 2, an extension 22 is detachably secured as by a press fit to the upper end of a shaft 23 with the extension 22 being pivotally connected to a fitting 24 attached to the lower end of the shaft 17.

When the shaft 17 is rotated about its axis such rotation is imparted through the joint 19 to the shaft 23 which is journalled by spaced bearings 25 secured to an upwardly extending section 26 of the base 3. The shaft 23 has fixed thereto a gear 27 which meshes with an idler gear 28 (Figs. 2 and 5) attached to an idler shaft 29 which is rotatably mounted by spaced bearings 26a carried by the section 26. As will appear hereinafter, the

gears

27 and 28 may be selectively driven by adjustment of the shaft 17 for permitting a change in the direction of rotation of the turntable.

At its lower end as viewed in Fig. 2, the shaft 23 has xed thereto a bevel gear 30 which meshes with a bevel gear 31 secured to the left hand end of an elongated worm shaft 32 which extends horizontally through an 3 opening 33 of the base 3 beneath the turntable 4. The shaft 32 is journalled by spaced sections of the base 3 and carries a worm 34 which meshes with a worm gear 35 secured to the turntable therebeneath, as best shown in Fig. 4.

The gear 35 is secured as by screws 36 to a support 37 which is attached by screws 38 to the turntable 4. The gear 35 and the turntable 4 are mounted for rotation as a unit with respect to the base 3 by a bearing arrangement 39 including a circular outer bearing race 40 which is carriedby the support 37 and a circular inner bearing race 41 supported by a block 42 in spaced relation with the race 40. Bearing balls are positioned in the space between the races 4t? and 41 to complete the bearing arrangement. The block 42 is attached to the base 3 so that when the shaft 32 is rotated the gear 35, the outer race 40 and the turntable 4 will be rotated as a unit relative to the inner race 41, the block 42, and the base 3.

According to the present invention the turntable 4 is arranged for adjustment relative to the base 3 and relative to the coiler head 1 so that various sized sliver cans may zbe properly positioned with respect to the coiler head. The turntable 4 is configured so that sliver cans of different diameters may be supported thereby. In Fig. 4 a sliver can 5 is illustrated in broken lines as `being supported by the turntable. However, a sliver can of smaller diameter than that illustrated may be carried by the turntable by means of an annular groove 4' formed in the turntable for receiving the lower edge of the smaller can. A sliver can of larger diameter than that illustrated may be supported by an attachment 4a detachably secured to the turntable 4 and having an annular groove 4b to receive the lower edge of the larger can. The attachment 4a may comprise a plurality of separate grooved attachments, if desired. It is apparent that the turntable can be designed to support sliver cans having various diameters.

In order to permit adjustment of the turntable, the -block 42 is adjustably carried by thebase 3 by means of a screw 43 extending through an opening 44 of the block 42 into threaded engagement with a member 45 of T-shaped cross section having its crosshead portion 45 positioned within a crosshead portion 4-6' of a horizontally elongated T-shaped slot 46 formed in the base 3. In Fig. 4, the block 42 is shown clamped to the base 3 by means of the screw 43 and the member 45 which has its portion 45 drawn upwardly into tight engagement with a shoulder of the base 3.

If it is desired to adjust the turntable 4, it is only necessary -to rotate the screw 43 to loosen the member 4S and rotate the shaft 32 in the proper direction so that the member 45, together with the block 42 and the turntable 4, may be moved along the slot 46 in the desired direction to any selected position along the length of the VWorm 34. The block 42 then may be clamped to the base 3 by tightening the screw 43. It is noted with reference to Fig. 3 that the direction of adjustment of the turntable 4 is parallel to the direction of extension of the worm shaft 32 and that the adjustment is conveniently effected without the necessity of removing the shaft 32 and the gear 3S from their operative positions, and disengaging the worm 34 and the gear 35. To effect 'the adjustment the turntable is moved in the desired direction along the slot which causes the gear 35 to rotate along the worm 34. The adjustment may also be made by holding the gear 35 against rotation and rotating the worm 34 to therefore effect movement of the gear 35 and the turntable along the slot 46. As best shown in Fig. 3, the slot 46 terminates at its right hand end in a circular opening 47 through which the member 45 may be withdrawn to allow detachment of the turntable 4 from the base 3.

As described previously, the worm shaft 32 is driven through bevel gears 30 and 31 from a shaft 23. In the present invention the direction of rotation of the shaft 32 and of the turntable 4 resulting from a given direction of rotation of the shaft 17 may be reversed by driving the shaft 23 and the gear 27 from the idler gear 23 rather than directly as illustrated in Fig. 2. As shown in Fig. 2, the gear 27 is driven directly from the shaft 17 to establish a given direction of rotation of the turntable for a given direction of rotation of the shaft 17. This direction of rotation of the turntable may be reversed without reversing the direction of rotation of the shaft 117 by merely detaching the extension 22 from the shaft 23 and attaching the extension 22 to the upper end of the idler shaft 29 as shown in broken lines. Such adjustment of the shaft 17 to the broken line position is permitted by means of the joints f8 and i9 and is readily accomplished manually. The extension 22 may be exposed for the adjustment through an opening of the column which may be normally closed by a suitable closure.

Although the invention has been described with reference to certain specific embodiments thereof, numerous modifications are possible and it is desired to cover all modifications falling within the spirit and scope of the appended claims.
