8 Claims. (Cl. 8-19) This invention relates to the treating of skeined yarns and particularly skeined rayon yarns with liquid re-agents.

It is common where skeined yarns are treated with liquids as in the washing, bleaching and dyeing thereof to hang the skeins on rolls and to advance the rolls either in a step by step or in a continuous manner through liquid baths or through showers of suitable liquids, and to rotate the rolls so that the skeins thereon are rotated and all portions thereof are more or less equally subjected to the liquids. If the skeins are rotated continually in the same direction on a roll it is possible for the yarn-to cling to the roll and wind up thereon thereby damaging the yarn. This is particularly true of fine rayon yarns. Hence an object of the present invention consists in rotating the skein supporting rolls first in one direction and then in the other as the skeins are advanced so that the skeins can not become permanently wound up on the rolls and damaged.

A further object of the invention is an im-- proved machine for treating skeined yarns with liquid re-agents, which machine is arranged to 2.5 advance the skeins and at the same time to rotate them alternately in opposite directions.

Another object is generally to improve upon skein-handling machines and methods.

Fig. 2 is a plan view of the machine of Fig. 1.

Fig. 3 is a section taken along line 3-3 of Fig. 2.

Fig. 4 is a sectional detail taken along line 44 of Fig. 2.

Fig. 5 is a perspective detail of a link of a carrier chain.

Fig. 6 is a perspective detail illustrating particularly the mechanism for reversing the rotation of the skeins.

Fig. 7 is a detailed side elevation of a modified form of mechanism for reversely rotating the skeins.

The skein washing and bleaching machine embodying the present invention includes a pair of spaced horizontal parallel side beams 10 which support parallel tracks 12 that constitute guide ways for the lower passes of a pair of skein-advancingchains 14, said chains comprising a plurality of pivotally connected links 16 having depending lugs 18 which are slidable in grooves 20 of the guide ways 12, see especially Fig. 4. The lugs are provided with inwardly directed pairs of vertical ribs 22 which provide channels 24 that are open at the top and the bottom and are adapted to receive the ends of a plurality of skeinsupporting rolls 26 which are extended transversely of the guide ways between the chains. Each roll at the same end thereof is provided with a spur gear 28 that meshes with the teeth of and rolls on a rack 30 that is secured to one of the side beams 10 and is extended parallel with the associated chain guide way 12. The other ends of the rollsrest upon and roll freely over a supporting plate 32 that is secured to the other side beam 10 beneath the rolls.- The two chains pass over sprockets 34 that are fixed to a shaft 36 that is suitably journalled on the side beams and, as here shown, is rotated in a step by step manner by means including Geneva wheels 38 which are fixed to said shaft. Said wheels are intermittently advanced by a continuously rotating shaft 40 that is suitably journalled on the side beams 10 and is driven by a gear 42 that is in mesh with a worm 44 fixed to a continuously rotating drive shaft 46. Said shaft 40 is provided with arms 48 having pins 50 that enter the successive radial slots 52 of the Geneva wheels whereby to advance them intermittently in the usual manner. The shaft 40 is also provided with circular discs 54 which engage the peripheral portions of the Genever wheels and hold them against rotation in a well known manner except when they are rotated by the arms 48.

Skeins a are hung from the rolls 26 and are advanced by the chains under a succession of pans 56 or other devices which provide showers of suitable reagents through which the skeins are moved, the waste liquid of the showers being caught by tanks 58 that are disposed under the pans and surplus liquid dripping from the skeins in passing from one shower to another falling into troughs 60.

As the chains are advanced the skein-supporting rolls 26, which are engaged with the rack 30, are caused to rotate, the direction of rotation in the apparatus herein shown being counterclockwise. The rotation of the rolls consequently causes the skeins to rotate and, if the rotation were continually in one direction, there would be considerable danger that the skeins might wind upon the rolls and become damaged.

It is an object of the present invention periodically to rotate the skeins in an opposite direction so as to unwind any skein that may become wound upon a roll. The mechanism for reversing the direction of rotation of the skeins includes spur gears 62 which-are inserted at frequent intervals along the length of the rack 30 and between interrupted portions or sections thereof, the upper portion of the teeth of the gears being in line with the teeth of the rack so that they can mesh with the teeth of the gears 28 of the skein-supporting rolls when said rolls are thereabove. Said gears 62 are fixed to shafts 64 that are suitably journalled in the side beam 10 that carries the rack and are driven at suitable speed by

intermeshinggears

66 and 68 from the drive shaft A6. The gears 62 preferably are so located that they are engaged with the gears of the skein-supporting rolls at times when the carrier chain is stationary. The position of the gears 62 and their speed of rotation also preferably is coordinated with [the rate of advance of the chains in such manner that the skeins are rotated equally in opposite directions, the ad-' vance of the skein-supporting rolls over the rack 30 causing the rolls and the skeins to rotate in one direction until the rolls are brought into engagement with the gears 62 whereupon the chains become stationary and the gears 62 thereupon rotating the rolls and the skeins in the opposite direction.

The chains automatically pass upwardly out of engagement with the rolls as the chains pass about the sprockets 34 and the rolls roll down inclined guide ways 70 and come into a final position convenient for their removal from the machine.

For some purposes it may be convenient or desirable to have the carrier chains 14 advanced in a continuous manner instead of in the intermittent manner above described. For such a movement of the chains, the skein-supporting rolls may not be in engagement with the reversing gears 62 long enough to reversely rotate the skeins the desired amount. Under such condition the modified reversing mechanism, illustrated in Fig. 7, can be employed. In this figure the reversing gearing 62 is replaced by an endless chain 72 the links of which have continuous gear teeth on their outer faces, which gear teeth are in line with and form in efiect a continuation of the gear teeth of the rack 74, which rack corresponds to the previously described rack 30. The chain 72 is mounted upon a driven sprocket 76 and is passed about an idler sprocket '78. The length of the upper pass of the chain 72 and its speed is adapted to be such that it rotates the continuously-advancing skein-supporting roll the desired amount in the desired direction during the time that the roll gear 28 is in engagement with the chain.
