lower of which runs partly submerged in a vat containing hot water, and it is equipped with forward and reverse movement, in order to be ableto wind `and unwind the fabric, whereas the upper cylinder is adapted to be raised and lowered and is loaded by weighted levers, so that it presses on the winding cylinder Wound more or less with the web of fabric, that is varying in diameter, and isY rotated thereby. A third, so called ductor .or take-o cylinder is yjournaled slidablyon an inclined plane in suchv a` manner that it always bears against the upper pressure ycylinder and is rotated thereby. VItV serves for vwinding the length of fabric to` be treated during completely from the lower cylinder, that is, vonly a comparatively small output can be obtained.

Contrary thereto, the machine according to the invention allows the simultaneous treatment Y of two lengths of fabric and consequently the at-V taining of double the output, in that during the unwinding of one length of fabric, a second .ength of fabric is already being wound.

The invention consists substantiallyy in `that Vthe upper pressure cylinder is arranged, not only so that it can be raised and lowered, but falso can yield towards both sides, over two winding cylinders, arranged in known manner side by .side and partly submerged in the liquid bath. Thus it bears on both winding cylinders and can at the same time .adapt itself automaticallyA to Ytheir actual diameter. TheV upper pressure cylinder is further of such weight or loaded by the weighted levers in such a manner that it transmits the rotating Vmovement of the one driven winding cylinder to the other loosely rotatable winding cylinder, thereby squeezing out' the wet web of fabric, and moreover bearing, arrangements are provided on both sides of the .upper pressure cylinder for the loose bearings of the ductor cylinder on the upper pressure cylinder in known manner so that the ductor cylinder can (CLS-1419)@ 'f n Y be journaled asdefsired on the one or the other side of thefupper pressure cylinder. l

Owing to this complete arrangement. according to the invention av webof fabric can be Wound on one `of the two winding cylinders and at the same time a second web of fabric, which hasbeen previously wound'on the other winding cylinder, can be unwound therefrom. The winding cylf inder, which is actually driven, rotates the kp'ressure cylinder, pressing 'tightly against it, Yin the 65 opposite direction lof rotation.l The pressure cylinder in turn rotates the second winding cylinder in the samedirection as that of the first winding cylinder. Accordingto Whether the fabricto be wound on the ductor cylinderY isunwound from 7o the one or the other winding cylinder, the ductor cylinder must be journaled either on theifront side oron the rear side ofthe pressure cylinder. The web of fabric unwinding alternately from the oneor the other winding 'cylinder is prefer- 75 lably guided at thetop around the pressure cylinder to the -ductor cylinder or takeoif. roller, journaled on the .opposite side. Thisfmethod of working presents. they advantage that the' web of fabric coming out of the bath is supported 80 and guided, that is held stretched by the pressure cylinder serving as bearing surfacealong its entire. path from the winding cylinder to the Vduetor cylinder. In the known simple boiling machine, in which the fabric web is conducted g5 from the winding 'cylinder directly aroundfthe ductor cylindenand is Ynot-'supported on such a bearing surface, a continual pulling j on the edges of the hot web of'fabriccoming from the bath is required. This constitutes a very disagreeable and tiring Work, in order to retain the width of the web of fabric, that is', toprevent the formation `of creases and for obtainingfthe uniform winding of "the, web on vthe'ductor cylinder. This workis saved by the particular arrangement of the bearing devices vfor the ductor, cylinder onlthe machine` frame and by the vabove mentioned methoduof employing themachine.v` l An embodiment'of the invention is illustrated 100 by way of `example in the accompanying drawings in which: n g y f f Fig. 1 shows the` machine in elevation, partly in section on line A-r-B of Fig.f2.""A Fig..2 is a side elevation, also partly in secg- 105 tion.

A further toothed .he shaft g3 at a distance el y1 and meshes with a 150 isc like-sized toothed wheel fyfi looselylmounted` on the shaft g4 and forming on its inwardly directed face also one half of a claw clutch. A claw clutch sleeve e is shiftably, yet not rotatably mounted on the shaft 114 between thetwotoothed wheels y2 and ys and has on its .end faces claws,l which fit-in the claw clutch halves formed on the toothed wheels y2 and ys. The claw clutch sleeves can be coupled as desired either with the toothed wheel y2 or with the toothed wheel y@ by meansofa fork lever el mounted'on the machine frame and having two pins which engage in an 'external annular groove in the clutch sleeve'z andl is provided on each side with engaging rods a2. Thus either the one or the other of these two toothed wheels y2 and ya can be rigidlycoupledfto the shaft g4. A belt pulley z3, shown infinixed lines in Fig. 1, is keyed ontheshaft 3/4 and serves for driving the machine by means of a belt. If the clutch sleeve z is coupled with the toothed wheel ye, and if the shaftyl is rotated in vthe direction indicated bythe arrow in Fig. 1, the two toothed wheels g5, y1 rotate in the opposite direction and consequently cause the toothed wheel y keyed on the axle of the lower squeezing cylinder h, and also the squeezing cylinder-h, to rotate in the direction of the arrow shown in Fig. 2. However the upper squeezing cylinder bearing on the lower squeezing cylinders h, z' is thereby 'rotated in the opposite direction, and through the intermediary of the upper squeezing cylinder lc the lower squeezing cylinder is rotated in the same direction as the lower squeezing cylinder l1.. By coupling the. clutch sleeve .e

' :l with the toothed wheel y2, thedirection of rotation of the shaft g4' remaining the'same, the three squeezing cylinders and k will be rotated in the opposite direction to the varrows shown on the drawings." The take oif cylinder u, bearing on the upper squeezing cylinder 'lc 'and rotated thereby, is always rotated in the opposite direction -to that of the cylinderlc.Y

When the three squeezing cylinders are driven in the directions indicated in the drawings, a pieceof fabrc E, piled on the left side of the machine as shownin Fig. 2, is rst conducted between the adjustable stretching device u1, u2, u, w1 and between the spreading device r1, s, s1, s2 arranged above same, then downwards around the stay rod m1, and then between the lower squeezing cylinder h and the upper squeezing cylinder lc, so that it can be wound on the squeezing cylinder h. During this winding operation a second piece of fabric F, which has been previously wound on the lower cylinder rotated in the opposite direction, is at the same time unwound from this cylinder i over the upper squeezing cylinder 7c and wound on the take off cylinder u mounted for this purpose above the lower cylinder h. During the passage of the piece of fabric F between the cylinders i and 7c, the liquid present therein `is squeezed out at the same time by the upper squeezing cylinder 7c. The operator can observe from his stand situated on the left side of the machine simultaneously the piece of fabric E winding on the lower cylinder h and also the piece of fabric F coming from the lower cylinder 'i and winding on the take off cylinder u. When the piece of fabric F is completely unwound from the lower cylinder i andwound on the take off cylinder u and if, during this time, the piece of fabric E has completely wound on the lower cylinder h, the operator inserts a second take off cylinder u in the bearing provided above the lower cylinder i,

take off cylinder'. He `then passes dfrom the other side of the machine a fresh piece of fabric G, previously folded at this=point, over the vstretching device u1, u2, a3, n4, the spreadingr device r, s, s1, s2, from'below overthe stay' rod x2 and between the squeezing cylinders z'and lc, so that this piece of fabric G winds onthe lower cylinder i.

In the drawings the machine is shown in the condition,iin whichfthe' drive ofthe machine is disengagedby bringing the clutch sleevewe into its central position, a piece of fabric beingpartly wound'on 'the lower squeezing cylinder h in the direction indicated bythe arrow and another pece of fabric rbeing partly unwound from the lower squeezing cylinder i and wound on the take off cylinderiu-mounted above the squeezing cylinder h.A f i Y For the purpose of facilitating the introduction intoV the machine' ofthe pieces of fabric to be treated, the` arms r, 11, lafter Vthe pins q Ihave been removed from the machine frame, are swung, togetherwith the stay rods of the spreading devices carried thereby, out of their horizontal working position into a downwardly inclined position, so thatv at the same vtime the stay rods m1, x2 arranged in the hot water vat g are swung upwards. Thepieces of-fabric"`to be treated can then be conducted without 'much difficulty over the stretchingand spreading devices. After the introduction of the pieces of fabric into thesey devices the spreading devices, and'therefore the stay rods :c1,"2, are swung back into their former horizontal position andY locked in this position by inserting-the pins q in corresponding bores of the machine frame. The inserted pieces of fabric are then'stretched and their tension lcan be regulated within certain'limits by suitably adjusting Ythe stretching devices u1, u2, a3, 11.4.
