Be it known 'that'l'; JACQUES Scrrrnirrr, 1a citizen oft-he Swiss"Confederation; residing at ()be1:--Winte1tl1u1',-Rychenbergstrasse 207, CantonZurich, Switzerlanch have invented new and useful Improvements in Machines for Treating Yarns in Hanks with Liquid, of which the following is'alspe cification.

The present invention relates to that of machinesfor continuously dyeing, washing and otherwise similarly treating yarn in hanks, in which a concentric series of tanks or rats have rotating above theln'a' concentric series of pairs of rollers upon and between which the hanks are suspended; By the rotation of the rollers upon their axes the hanks are continuously run throughthe liquor inthe' troughs or vats below, and" by the concentric motion" of the rollers the hanks aresuccessively transferred from one vat to the next through the series. V

In, such machines one of the rollers of one pair, the one carrying the hanks is pressed by suitable devices against the second roller of a pair which is driven by suitable gearing from amotor: The roller carrying the hanks is driven by friction atthe same time the liquid is squeezed out of the yarn which runs in and'out of the vat.

Accordingto the present" invention means are provided to adjust simultaneously and uniformly the pressure exerted on the yarn and" to prevent any excess of pressure. Moreover meansare provided to part the rollers at certain points of their circular pathto take-off andreplacef the hanks.

Inthe accompanying drawings one form of construction is shown byway of an example.

Themachine shown comprises a circular series of vats l'having'radial walls'or divisions 1 separating adjacent vats. Above the vatsl a series of pairs of

rollers

13, 21 is"arranged on a frame 12 'rotatably mounted ina stationary framed. The frame 12 is frame 6 andcarries at'its held fast in the frame 12;

Said bevel wheel 7 engages a bevel wheel-8 rigidly fixed to the bossof-abevel gear 9 on ashaft 10.v The shaft 10 runs in radial direction and isirotatably mounted in bearings 11' of the frame 12. Thebevel gear 9 engages'similar bevel gears 9' of ad jacentishaft's 10 which are allarranged in radial directions at equal distances apart eachshaft 10 driving thenext fo llowing by its bevel gearS). .On' the sleeve .18 of frame 6 a spur wheel" 17" is rotatably mounted which is in mesh with a spur wheel 16 keyed to vertical shaft 15., The latter is driven b .means of abev'elgear 1 1 by the gear 25 igidly fixed to the said-spur wheel 171is the frame .12 vwhichisj supported by rollers 19 journa lled on pins 20 of the frame 6. The frame 12 supports the bearings 11 for the shafts 10. On each shaft 10 {a roller 13 for instance of rubber is rigidly fixed. (looperatinglwith each roller 13 is ajroller 21 loosely'mo'unted on a shaft 61. The roller 21 and the shaft 61 run parallel to roller 13 and shaft 10. The shaft 61 isrigidly fixed to an arm 22-of a sleeve 62 rotatably mounted on a shaft 44. which shaft 4 1 is On the sleeve 62 a spur wheel 13 is'fastened' which is in mesh with a toothed segmentu42 rotatably mounted on the shaft .42. The said segmentlO is provided With a downwardly projecting noseelwhich nose 4:1 strikes against cams 39 adjust-ably mounted onthe frame 6 as soon as the frame 12 isrotated bythe said gear 2. If nose 41 strikes; against a cam 39 the segment42 rotates on shaft 10 and rotates the sleeve 62 by means of the spur wheel 43. The arm" 22and therewith shaft 61- and roller 21 is swungout (Fig. 5). The

rollers

13 and 21 are "moved apart and be placed on the roller 21. As soon asnosei 41 has passed the cam '39 the roller 21 falls down by its own weight and the brought in contact wit-h the roller 13 (Fig. 6

from one vat to the adjacent vat the roller 21 may be lifted to pass the hanks A clear over the partition walls.

0 press the roller 21 on to the roller 13 to press-off the liquid in. the hanks A a double armed lever 23, is rotatably mounted on the shaft 61. One arm 25 thereof projects downwardly, the other armrests on a slanting plane 38 of a double armed lever 26, 27 rotatably mounted on a vertical shaft 28. (in theframe 6 camsol are adjustably mounted which project the frame 12 rotates the arm 25 strikes against the cams 51 (Fig. 3) the lever 24 rotates on shaft 61, and the upper arm 24 slides along the slanting plane 38 rotating thereby the lever 26, 27 on its shaft 28 against the action of a spring 31. The spring 31 is interposed between a rod 29 linked to arm 27 and the bars 30 linked by a bolt 34 to the rim of a sleeve 33. Said sleeve 33 is rotatably mounted in the upper wall 32 of the frame 12. A lever 35 is fastened to the upper face of the sleeve 33, the free end of said lever 35 is bifurcated and embraces a nut of a screw-threaded spindle 37. A hand wheel 36 is fixed to said spindle 37 which is attached to a pivot mounted on wall 32. On turning the wheel 36 the nut is moved on it and the sleeve 33 is rotated compressing or releasing simultaneously the springs 31 of all the levers 26, 27. The pressure exerted by said springs 31 on the lever 26, 27 and on the roller 21 (if the

lever

24, 25 has been turned on its pivot 61) may be varied by rotating the sleeve 33, as the levers 26, 27 offer more or less resistance against turning by arm 24 according to the pressure of the spring exerted on it. If the arm 22 is raised (Fig. 5) the arm 24 moves along an extension 45 of the arm 26.

Th machine works as follows:

The frame 12 with the pairs of

rollers

13, 21 is intermittently advanced in such'a manner that the pairs of rollers remain. some time above one vat. The hanks on the rollers 21 are turned as soon as they are pressed against the power-driven roller 13 by the roller 21. The liquid in the hanks is squeezed-off as soon as arm 25 passess on the cam 51. The parts of the machine are adjusted in such a manner that the arm 25 rests on the corresponding cam 51 when the frame 12 comes to rest after an advance while the roller 13 is rotating. The hanks are turned and pass througi the liquid of a vat the liquid is continuously squeezedofi'. The gear 2 is constructed in such a manner that the direction of rotation of the rollers 13 is reversed each time the frame 12 is advanced. This change of direction of rotation is taken recourse to in order to prevent that the individual threads of the pair skeins or bundles get tangled up. Experience has shown that if a cord or yarn is held under tension in the same direction for considerable time, that is, if it is imder a rotary strain, some of the threads are advanced more rapidly than others. The threadsof the yarn, therefore, get tangled up and the yarn becomes useless. It is quite well known, and not claimed as novel in the present application, to change periodically the direction of movement of the device. The yarn is being moved for a certain eriod in one direction and for the same period in the opposite direction. The hanks A mov alternately in opposite directions in two consecutive positions and are kept in good order. \Vhile the hanks A pass from one vat to the other the roller 21 is raised by the cams 39 and gears 42, 43 as described and the hanks A remain at rest. After the hanks A have passed all the vats they may be taken-off, a cam 39 being provided to lift the roller 21 from roller 13 at this point.

The number of pairs of rollers and the number of vats may be varied according to requirement.
