The inner end of the fabric winding is secured to the periphery of the inner drum or core I!) oi the roll as indicated at H. The outer end portion ii of the roll of material is unattached, whereby the roll is free to unwind when the roll is rotated.

Atthe start of the operation the outer end portion it of the fabric winding hangs freely as illustrated in dotted lines in Fig. 2, but upon rotstion of drum ill, sold fehric portion it is impelled by centrifuged force towerd the inner surface of the outer drum it, end is thereby caused to proiect through the liquid L contained in 01mm it into engagement with sold inner surface oi the outer drum.

For the sake of clearness, only a few convolutions of the windings are illustrated and the convolutions are shown spaced from each other radially of the center of the winding. but it will be understood that in actual practice the convolutions of the windings on the inner and outer drums are adjacent each other.

After the fabric is completely unwound from the inner drum ill, into the form of a roll RA in the outer drum, said fabric is re-wound on inner drum it. This is accomplished by continuing the rotation of the inner and outer drums in the same direction and at the same relative speeds, that is the inner and outer drums rotate in the same di rection but outer drum i2 continues to rotate faster than inner drum it. This re-winding oi the material from the roll EA to the roll R on the inner dum iii accomplished as just stated without altering the direction or relative speeds of rotation or" said drums, takes place by reason of the fact that the inner end of the material of the winding is as previously stated fixed to the periphery oi the inner drum. Fig. 6 of the drawings illustrates the step of rewinding the material from the roll RA to the roll It on. the inner drum it, and it will be observed that the direction of winding of the material on the inner drum is at this stage 01 the process opposite to the direction of wind of the material of roll R at the start of the process illustrated in Fig. l.

After the material is re-wound on the inner drum iii, in the stage of the process just previously mentioned, said material is again caused to unwind from said inner drum it and to again arrange itself in the form of a winding RA adjacent the inner surface of the outer drum i2. This is accomplished without interrupting the rotation of the inner and outer drums and without changing the direction of rotation of said drums, but by now reversing the relation of the speeds of rotation of said inner and outer drums, in other words by now rotating the inner drum iii faster than outer drum [2. Fig, 7 shows the material partially unwound from the roll R at this stage of the process, that is by rotating inner drum Ill faster than outer drum it, the different revolutions per minute between said drums being about the same as at the start of the process. Fig. 8 shows this stage of the process completed, the material being completely unwound from the inner drum l0 and arranged in the form of a winding RA on the outer drum 12. Then the fabric is again rewound on the inner drum I0 by continuing the rotation of said drums in the same direction, with inner drum I0 rotating faster than outer drum 12 until the material is again completely re-wound on said inner drum. At this stage of the process the winding of the roll R of material on the inner drum is in the same direction as it was at the start of the process as herein described. This is illustrated in Fig. 9.

The above described steps are repeated as often as is desired or necessary for the proper treatment of the material, or as will be readily understood, in some cases it may be necessary merely to unwind the material from the inner drum and to arrange it in the form of a winding in the outer drum, or to complete only one cycle consisting of unwinding the material from the inner drum, arranging it in the form of a winding in the outer drum and then rewinding the material on the inner drum.

The apparatus which will now be described and whichis illustrated in Figs. 1 and 2 of the drawings is well adapted for performing the above detions of said drums.

scribed method. As here shown, the outer drum i2 is carried by a sleeve or hollow shaft 20 journalled for rotation in bearings 22, said outer drum 52 being thus mounted for rotation. The inner drum it or core of the roll of material is mounted for rotation within outer drum i2 and for that purpose is, as here shown, carried by and for rotation with a spindle or shaft 2d which extends through sleeve ll'ii into drum i2. Shaft 2a is mounted for rotation within and in relation to sleeve 2a in any suitable manner, as for example by means of roller bearings 26 mounted within sleeve 29. Sleeve it has a gear 28 fixed thereto. Said gear is driven by a gear Eli fixed to a rotary shaft 32 driven in any suitable manner, as by a pulley 3d operated by a belt 36 driven by a motor lvl'.

Provision is made for rotating the inner and outer drums at different speeds, more specifically by rotating said drums so that one alternately r0- tates faster than the other. For this purpose shaft 26 is provided with relatively large and small gears and dd, respectively, which mesh with relatively small and large gears 32 and dd, respectively, on shaft 32. A two-way clutch 46 is splined to shaft 24 whereby said clutch can move longitudinally of the shaft but not circumferentially thereof, said clutch being thus rotatable with shaft 26. Gears 38 and 38, on the other hand, when disengaged from clutch fit can move freely about said shaft but are fixed longitudinally thereof. Gears i2 and dd are fixed to shaft 32' longitudinally thereof and rotate with said shaft, and are at all times in mesh with companion gears 38 and tit, respectively.

Said last mentioned gears are provided with clutch engageable elements ill and 50, respectively, for eiiecting rotation of said ears when engaged by said clutch. A yoked lever 52 pivoted as at 58 is provided for moving clutch 46 into en gagement with gears 38 and. 4B alternatively. It

will be understood that when the clutch is in engagement with gear 38, shaft it rotates more slowly than sleeve 2t with the result that outer drum 52 rotates faster than inner drum l0. When, however, it is desired to reverse this relation of speeds of rotation of said inner and outer drums, clutch 6t is disengaged from gear 38 and is engaged with gear 46, and in that case shaft 24 rotates faster than sleeve 20 and of course inner drum Ill rotates faster than outer drum l2. Y

In accordance with the present invention, provision is made for automatically periodically reversing the relation of speeds of rotation of the inner and outer drums, or more specifically to automatically rotate one drum faster than the other after a predetermined number of revolu- A mechanism suitable for this purpose is illustrated in Fig. 1 of the drawings. As here shown, said mechanism comprises a worm gear 52 fixed to and rotated by shaft 32.

Said worm gear meshes with and drives a worm wheel 54. Said worm wheel is provided with a metal segment 56 connected in series with the winding W'of an'electro magnet 58. More spefore, that when-electro-magnet 58 is energized,

llii

which is the case as long as brush 68 is in engagement with segment 58, armature 8B is attracted and holds clutch 46 in engagement with gear 38. When, however, after a predetermined number of revolutions of shaft 32, brush, 66 is disengaged from segment 56 so, that the circuit through windlug W of electro-magnet 58 is interrupted, spring 12 is effective to actuate the yoked lever 62 whereby to disengage clutch 48 from gear 38 and to engage said clutch with gear 40. Thereafter as worm wheel E l continues to rotate, brush 86 again engages segment 66 to complete the circuit through winding W of the electro-magnet 58 for attracting the armature 68 on yoked lever 52, thereby disengaging clutch 46 from gear 48 and engaging said clutch with gear 38.

As illustrated in the drawings, provision is made for supplying liquid to drum l2 and the liquid supplying device is such in accordance with the preferred form oi the invention that the supply may take place during rotation of the drums. For this purpose a fluid delivery pipe it, pivotally mounted as at it on a supply pipe I8, is provided. Said delivery pipe i i has a bent portion 89 which extends through opening ill in the front of the drum it to a point adiacent the inner surfaces of said drum. It will be understood that opening it is large enough to permit the passage of the bent portion iii of delivery pipe it to said opening into and out of the drum, said delivery pipe being turned on its pivot it for such purposes. A pipe arrangement similar to the arrangement for sup-=- plying liquid is preferably provided for exhausting liquid from drum l l. Thus as here shown an enliaust pipe 32 similar to delivery pipe M is mounted on pivot lit for turning movement about a pipe Exhaust pipe it has a bent portion it which passes through opening It and terminates adjacent the inner surface at outer drum it. Thus both delivery pipe it and exhaust pipe iii are associated with the apparatus so that liquid may be supplied to and removedlrom drum it during the rotation thereoi. Accordingly, circulation of the dye or other liquid may take place during the treatment of the material while the latter is on wound from roll it and rewound into said roll.

It will be understood that the front of the drum in which the opening it is provided is preferably removably secured to the front peripheral edge of outer drumlt. as here shown, said front end of the drum is provided with an observation opening sealed by a glass or other transparent win dow d'i. The front wall of drum i2 is removable to permit the insertion and removal of the fabric roll R, the inner drum I or core of the roll being removable from spindle or shaft 23, suitable provision being made for fixing said inner drum to said shaftso as to rotate with the latter. It will he understood that as herein described the inner drum it may be a member which remains permanently on the shaft 24 or may be the core of the iabric roll.

Thus it is seen thatthe method and apparatus hereihbefore described are well adapted to accomplish the obiects of the present invention. It will he understood that while the present method and apparatus are intended primarily for use in the dyeing oi fabrics, especially broad iabrics, the method and apparatus may be used for other purposes, for example for washing fabrics or other materials or for subjecting said fabrics to treatment by gases, vapors, or other fluids, the present method of winding and unwinding the fabrics being especially suitable for thus exposing successive portions of a roll of material to the action of various fluids. It will be understood also that while I have illustrated and described the preferred form of the method and the preferred form of the apparatus, variations in both method and apparatus will occur to skilled artisans in view of the present disclosure. Therefore, I do not wish to be limited to the method and apparatus or to either of them, as herein specifically shown or described, except as may be required bythe scope of the appended claims.
