APPARATUS FOR BLEACI-IING, DYEIN'G, 8w.

Application filed November 6, 1919.

T 0 all whom it may concern:

Be it known that 1, MAX Pon'rzsoH, a citizen of the United States, and a resident of Clifton, in the county of Passaic and State of New Jersey, have invented a newand Improved Apparatus for Bleaching, Dyeing, &c., of which the following is a full, clear, and. exact description.

This invention relates to an apparatus which eliminates or avoids permanent creases in a piece or string of cloth when dyeing, bleaching or washing the same, and also shortens the process involved.

Another object of the invention is to provide a construction wherein strings or strips of cloth are automatically changed and refolded in a more or less continuous action during the dyeing, bleaching or washing operation so that permanent creases will not be formed in the cloth.

A further object of the invention, more specifically, is to provide an apparatus with a roller which may be formed with raised and depressed portions alternately in a sealloped formation, and a spreading or refolding'member co-acting therewith for causing the cloth to be refolded as it passes over the rollerand thereby prevent the formation of permanent creases during the operation of the apparatus, whether it be dyeing, bleach-- ing or washing.

roller tothat shown in F ig. 2, the same being on an enlarged scale.

Referring to the accompanying drawings by numerals 1 indicates a support of any de- SII'GCl lIlHCl for a container 21which is substantially segmental in cross section as shown in Fig.1; this shape being provided merely for the purpose of convenience. Ar ranged in the container 2 is a supply'of liquid which may be dye, a bleaching; compound or washing liquid, said liquid being prepared for acting on the string of cloth passing therethrough for producing the results desired. Arranged above the container 2 is a comparatively large driving roller 4 accommodating the strips or strings of cloth 5. Any number of pieces of cloth may be caused to move over the roller 4, preferably a' comparatively large number so that a large quantity of cloth may be treated when used in any of the apparatuses .mena tioned, namely dyeing, bleaching or, wash ing machines, a plurality of pieces of cloth of any length, as for instance thirty yards connected in strings so as to make continu: ous belts. As many of these strings are placed on the roller or drum 4 as the same will accommodate, the strings being ar ranged so that most ofthe clothwillbe in folds 6 in the container@ as shown in Fig. 1, while the upper part of the cloth will pass over the drum or rollert, refolding roller 7 and spreading member 8. A guide 9, similar to that shown in Fig. 7 is used for maintaining the strings separate as they leave. the liquid. These guides are made from a suitable frame 10 having partitions 11, said frame being secured in place on the container 2'by any desired means, as for instance screws. Preferably a perforated division board 12 is provided near the wall 13,. though this is not always necessary. The refold roller 7 is what may be termed fluted as it is formed with reduced portions or sections 14 and with bulged or raised sections 15 alternately for the full length of the roller. This roller carries a suitable supporting shaft to which the sprocket 16 is secured, said sprocket accommodatinga chain 17 passing over sprocket 18. Sprocket 18 is rigidly secured to shaft 19 connected with the drum 4 and with a driving pulley 20. Pulley 2O accommodates a belt 21 which "passes over a small pullev 22 rigidly secured to the shaft 23 extending through the spreading member 8 to which it is rigidly secured. The member 8is substantially diamond shape in cross section as shown in Fig. 1 with the points rounded and with alternate depressions 24 and raised portions 25 arranged in line with the depressions and raised portions 14 and 15. The belt, 21 is arranged so as to drive the spreading member 8 at different speeds under different circumstances. Usually'when the spreading member is moving with the goods it moves slightly faster than the goods, but when moving in a directionopposite the direction of the movement of the goods'it moves much slower than the goods. By reason of the chain 17 it will be seen that the roller 7 moves always in ,one direction with the drum 4, and by reason of the size of the sprocket wheels 16 and 18 and roller 7 has the same peripheral'speed as the drum 4. If desired the peripheral speed of the roller 7 may be slightlymore than the drum 4 so as to assi'st'in spreading as well as refolding the cloth. As the roller 7 rotates and as the spreadingmember 8 rotates the cloth will have a tendency to move over the reduced portions 14 and 24 upwardly toward the raised portions 15 and 25 and thereby become folded longitudinally at a new'place. When any particular point of the string gets around again to the roller 7 it will not be folded at the same place that it was before, caused by the tendency of the cloth to climb to the highest point, and consequently permanent creases will be prevented. After the various strings 5 of cloth havebeen arranged imposition the apparatus is start ed and the strings are gradually moved through the liquid continuously for any desired length of time, as for instance from one hour to siX or eight hours, according to the liquidused, the cloth and other controlling circumstances. The apparatus may be driven by anysuitable source of power which is preferably connected to the driving pulley 26 secured to shaft 19.

In Figs. 3 to 6 inclusive will be seen a slight ,modified form of the invention in which the different construction consists in the use of a special form of spreading means 27. The spreading device 27 consists in a flat section 28 having a scalloped edge 29' for causing a movement of the cloth laterally of its direction of travel. To better accomplish. this result the spreader is connected to a rotating disk 30 through a link 31. The disk 30 is securedto shaft 32 which carries a worm wheel 3 33 meshing with the worm 34. The worm 34 issecured to the shaft 35, said shaft carrying a sprocket 16 and the re-folding roller 7. In this way as the drum 4 and roller 7 are rotated, the spreader 27 will be movedback and forth, said movement being preferably slow compared to the rotary movement of the roller 7.

In Figs. 8 to 10 inclusive will be seen a further modified form of the invention in which the modification consists in the use of a modified form of spreader 36. This spreader consists of aflat plate or board 37 having a plurality of spaced eyelets 38. The board 37 is supported on a suitable frame work 39 by pivotally mounted connecting links 40 and 41 whereby as the board 37 and associate parts are moved back and forth the board will be moved up and down also. The length of the links 40 and 41 andthe spacing of the eyelets 38 are such that the center of the eyelet will move from the center of he enlarged portion 15 to the center of the reduced portion 14 of the roller 7 during the operationof the machine. This back and forth motion of the eyelet will assist the roller 7 in refolding the string continuously so that the string or cloth will not be folded twice in the same place and thereby will not form permanent creases. The means for reciprocating the spreader 36 may be any suitable means but preferably it is the same arrangement of eccentric and link structure described in respect to Figs-4 and 5 so that it will need no additional description.

In Fig. 11 willbc seen a preferred form of roller 7. It is, of course, evident that the roller 7 could be turned from one piece of wood or other material, but preferably it is constructed as shown in Fig; 11, wherein there is provided a central base42 which may be wood or other. material and extends for the full width of the vat2. This base is provided with aswelled section 43 adjacent each bulged or raised portion 15. Each of the swelled sections 43 is provided with stepped formations 44 and 45 and a central raised portion 46 which receives the central block 47, which block is wedge shape. 011 each side of the block 47 a number of disks 48 are provided, each disk being successively smaller as they recede from the block 47 so as to produce the rounded or bulged portion 15. The reduced portion 14 is preferably made from a solid piece of material, as for instance wood, though if desired it could be made from other material. Preferablythe central portion 44 and the blocks47'are secured to the base 42 in any suitable manner, as for instance by screws or keys, while the disks 48 are permitted to freely rotate on the stepped formations of'the base. The base 42 may be connected with a rotating mechanism as shown in Figs. 2, 5 and 10, or may be held stationary so that the cloth'will rotate the disk. When the base 42 is held sta- V tionary it is preferably positioned So'flthat the cloth .will first engage the disk near the sharpened endAQ of the block 47; whereby as it passes over the disk toward the roller. or

drum 4 it will be spread positively so that it tinuous movement, and means for longitudir na'lly. refolding the: cloth each time it passes over said feeding means.
