'(01. a rs1) The present invention relates to a machine for treating material with liquors, and is designed to provide such a machine that achieves a better distribution of the liquors through the material,
one wherein the cost of operation is reduced, and
wherein the time necessary for the operation is reduced. The machine is especially applicable to dyeing fabric piece goods, although as will be apparent from the ensuing description, it is capabio of much more extensive uses, such as bleaching, washing etc. of such goods. The description is related to its use for dyeing; since this illus trates the principles involved.
In general, there are three kinds of, dyeing that are employed for coloring fabrics and the like,
These are direct color dyes, sulphur'dyes and fast or vat color dyes. It will be understood that there may be other categories, or the above may be grouped diflferently, but it represents a satisfactory separation. In direct color and sulphur color dyeing, the coloring material is put into vats where it exists in a solution of the proper concentration. In the third class, the color may be applied in the same way, or it may be padded 5 onto a fabric in pigment form and subsequently run through liquid chemicals that dissolve the color and impregnate the material with the solu-- tion. The present invention is adapted for use with any of these three kinds of dyeing. In view 30 of the obvious similarity in the processes, the
description will be limited to its use in connection with fast vat color dyeing, since this should clearly show how it wouldappiy to all of them,
' and will also demonstrate its applicability to other 35 operations such as those above noted.
As stated, the dye chemicals are reduced to a solution with water and located in suitable vats. The dye chemicals are normally insoluble in water, a condition necessary to their being fast, 40 particularly when used for washable goods. Consequently, in order to get the dye chemicals into solution, they are mixed with proper agents. Generally these are reducing agents, such as sodium hydrosulphite and caustic soda, the chemicals 5 employed being such that when thus reduced, they are soluble in water. The cloth to he dyed is then moved through the dye solution and in its passage therethrough the interstices between the fibers oi the material hecome charged with 50 the dye solution. After the material has been run through the dye solution enough es to ohtnin the proper coloration, it is subjected to oxidizing agents that react with the dye chcal unri set it in the cloth in a state that is not solu hie in The dyeing. action is any rnev chanical in the impregnation. of the cloth by the liquid and partially chemical, the latter including both the oxidizing function described and in all probability certain reactions between the chemicals and the fibers of the material. 5
The above dye materials are expensive. It. therefore, is an object of this invention to provide a method and apparatus reducing the quantity of materials necessary. I
In particular, air acts as an oxidizing agent I which will set the dye. Where the material is being run several times through the dye solution, it it is exposed to air in between these passages, the dye will at least partially oxidize, so that when it returns to the dye liquid, the reducing agents 15 there present will act upon the thus oxidized dye, thereby decreasing the concentration of the sup-- ply of reducing agents, Consequently, it is an object or this invention to substantially eliminate any exposure to air during the process of 20 impregnating the cloth with dye material.
It is a further object of the invention to reduce the time required for the dyeing process. Ordinarily the material is nm from one roll to another roll through a vat of dye solution, both of the rolls being out or this solution. Consequently, the time a given section of cloth is actually submerged in the dye solution is only a very small proportion of the total time or the operation of this old process. In the present invention, the cloth is almost constantly exposed to the solution during the entire time of the dye process.
It is a further object'oi this invention to produce superior impregnation of the coth by the dye. Where the cloth roll is outside of the dye vat, when the cloth is wound onto the roll, the tension in the cloth and the squeezing of it forces the liquid dye out. Instead of flow through the cloth, it has a tendency to flow toward the opposite edges oi' the roll, with the result that the 40 selvedges oi the cloth have greater concentration of dye than do the center portions. Furthermore, the spreading action is irregular. In the prt invention, it is an object to provide a squeezing or the dye through the cloth material M by a rolling action to cause superior impregnation and to avoid irrerity of e trihution oi dyeing mute-rial across the ease oi" the cloth.
it is n iurther ohiect oi the invention to design a mac, the shape at which reduces the unentity oi" dye material necessary. hnecihcnily, it is an ohject to provide such it machine wherein the displacement oi the dye solution, produced hy the increueing oi the roll oi cloth,
the levei oi the solution in the vet to he so as to be maintained above the roll, thus reducing the initial quantity of dye solution.
It is a further object to provide a dye machine having no crevices on the inside thereof that collect the dyestuffs and resist cleaning.
It is a further object of the invention to provide a special safety control device that releases anyone becoming entangled with the rolls.
Other objects will appear as detail discussion proceeds. In the drawings: 2

Fig. 2 is an end elevation with a portion broken away on one of the roller axes.
Fig. 3 is a section on the line 3-3 of Fig. 2.
Fig. 4 is a plan view of Fig. 1.
Fig. 5 is a section on the line 5--5 of Fig. 3.
Figs. 6-9 are views showing successive steps in the operation of the device.
In the drawings, l8 indicates a frame support secured to the floor or other foundations, the frame comprising four legs I I formed in pairs, one pair being joined across the top by a horizontal cross member l2 and the other pair being joined by a corresponding horizontal cross member I3. Projecting upwardly from the cross member I2 is an upright i4, and projecting upwardly from the cross member I3 is an upright l5. Each of the uprights is provided with paired brackets, providing a vertical track l6 in which a roll is supported with its center core stayed by the elements of each bracket.
A dual vat member 20 having two sections 2| and 22 is supported by the legs Brackets 23 extending from opposite legs are welded to the bottoms of the sections 2| and 22 and bolted to the legs. The vat member 2|], in section 2| has an end wall 24.. In section 22 it has an end wall 25. A common intermediate partition wall 26 joints the section 2| with the section 22 and it not as high as the ends walls for a reason to be described. The section 2| is provided with a semi-cylindrical bottom wall 21 and the section 22 with a similar bottom wall 28. The brackets 23 are secured to the outside of the bottom walls '21 and 28.
Side walls 29 and 36 extend across both sections. Each of these side walls is provided with a cutout 3| extending downwardly from the topthereof, into which cutouts are fitted plates 32, the plates being bolted to'the walls by bolts 33. Preferably the bolts terminate short of the inside face of the respective walls as shown in Fig. 5, thus avoiding the presence of irregularities in the inner surface of the vats. The plates 32 are provided with flanges 34 through which the bolts 33 extend and each is also provided with an oifset 35 extending in flush with the inner face of the vat wall, so as to provide smooth inner surfaces for the vats.
Each plate 32 is provided with an opening 36 adapted to receive a packing gland 31 that may be removably secured in place as by bolts 38. Through the pair of packing glands 31 in the vat 2| extend the axle ends 46 of the roller 4| Through the packing glands 31 of the vat 22 extend the axle ends 42 of the roller 43. These axle ends are journaled by removable bearings 49 in the horizontal cross bars l2 and I3 of the supporting frame I. As is shown, the packing glands extend a certain distance into the respective vats. In order to accommodate for this and to reduce the width of the device, the rollers 4| and 43 are countersunk; providing pockets as at 44, in Fig. 5, to receive the packing glands 31.
Each of the rollers 4| and 43 comprises a spacer element 45 fixed to its axle, outside of which is a supporting shell 46 and a suitable coating material 41. The coating material may extend around into the pockets 44, providing a close fit with the packing glands 31. The coating material may be any desired substance, such as rubber.
A roller 50, having an axle 5| is journaled in the uprights 4 and i5. The supply roll of cloth 52 rests upon the roller 50, is supported thereby, and guided in the track l6.
Outside the cross bar |2 of the frame, the axles 40 and 42 have secured thereto clutch members 54 and 55 respectively including the beveled elements as shown. A shaft 56 is supported by brackets 51 and 58 on the cross member I2. Slidably, but not rotatably, mounted on the shaft 56, are a clutch member 59 complementary to clutch member 55 and a clutch member 60 complementary to clutch member 54. An operating bar 6| extending all the way around the machine is supported on the cross member |2 of the frame by slide bearings 62 and to the cross member l3 by slide bearings 63. A fork 64 engages the clutch 59 to slide it on the shaft 56 and a fork 65 engages the clutch element 60 for such movement. It will be seen that when the clutch element 59 is in engagement with its element 55, the clutch element 68 will be out of engagement with the element 54 and vice versa. Also a neutral position may be assumed wherein both rolls are free. The shaft 56 is driven from a suitable power source. If desired, an end bracket 66 may be secured to the frame for additional support for the shaft 56.
At the middle of the shaft 56 is a two-way clutch device comprising two opposite clutch elements 61 and 68 mounted'for rotation with the shaft, and slidable therealong. A lever 69 is provided for actuating this clutch. Either of thesetwo elements 61 or 68 may then, by oper ation of the lever 69, be brought into engagement with a driven element 10, on the end of a vertical shaft The shaft 1| is journaled to the upright H by suitable journals I2 and 13. At the upper end of the shaft H is a bevel gear 14 meshing with a corresponding bevel gear 15 on the axle 5| of the intermediate roller 50. It thus is apparent that the roller 56 may be rotated in either direction by operation of the lever 69, or may idle when the lever 69 is in a neutral position.
0n the opposite ends of all of the axles 40, 42 and 5| are pulley wheels 86 over any of which may be looped a brake strap 8| having a weight 62 at one end thereof. The strap is secured at its other end to a peg 83. The weight 82 causes friction and by such braking action prevents the rolls, over which the strap is looped, from overriding.
A dye by-pass drain 99 controlled by a valve 9| is connected to a pipe 92 leading from the vat 2| through a control valve 93; and to a pipe 94 leading from the vat 22 by way of a control valve 95. As will be shown, these valves provide for directing dye solution from either vat to the other, from either vat to drain into pipe 99, or from both vats to drain into pipe 90.
The operation of the device is as follows:
Referring first to Figs. 3 and 6-9, wherein the operation is disclosed sequentially, the operation may be explained. In Fig. 3, a supply roll of cloth, 52, is placed in the track l6 to rest on the intermediate roller 59. The level L| within the vat 2| is raised until it just covers the roller 4|.
The clutches are at this time all in neutral position. The end of the cloth from the 'roll 52 is then drawn down and wrapped around the roller 4|, as shown in Fig. 3. If desired, the liquor level may be maintained below the roller until the cloth is thus started thereon, and then brought up over the same. Such procedure obviates the necessity of the operators dipping his hands into the solution. The brake strap 8| is looped over the pulley 80 of the roller 50. The bar 6| is shifted to engage the clutch elements 54 and 60 to rotate the roller 4| in a counterclockwise direction. This causes the cloth to be drawn off of the roll 52 across the roller 50 now operating as an idler, retarded by the brake strap, and to be wound onto the roller 4|. At this time, of course, the roller 43 is not operating. The cloth being drawn through the dying fluid becomes inpreghated. thereby. As the diameter of the roll of cloth on the roller 4| increases, its displacement of the liquid increases and the level L| thereof is raised, as shown in Fig. 6, so that this level always remains at least slightly above the top of the roll. Rotation of the roller 4| is continued until the cloth is entirely wound thereon.
Shortly before all of the cloth is wound onto this roller 4|, the level L-l will have been raised to such a point that a certain portion of the fluid within the vat 2| will have been displaced over the center wall 26 into the vat 22. When the entire roll 52 is wound onto the roller 4| the core of this roll 52 may be removed, if desired.
The end of the cloth'from the roller 4| is now carried over the roller and looped onto the roller 43. The dyeing liquor level L--2 within the vat 22 may now be raised until it comes just over the top of the roller 43. This raising may be effected by closing the valve 9|, and opening valves 93 and 95 so that liquor from vat 2| will seek its level in the vat 22, and any necessary additional liquor added to provide the proper level and concentration within the vat 22. However, this operation of transferring from one vat to another may be restricted, since it is desirable to maintain the roll of. cloth on roller 4| submerged so as not to be exposed to air. The controller arm 6| is now shifted to disengage the member 60 from the member 54. The brake strap is now looped over the pulley 80 of the roller 4|, this roller being free in the next operation. Following this, thearm 6| is further shifted to engage the member .59 with the member 55 so that the roller 43 is rotated clockwise and the roller 4| is free. The cloth is then wound, as shown in Fig. 7, from the roller 4| onto the roller 43, the level L--2 rising with the increasing displacement of the cloth wound onto the roller 43 and the level L-| dropping correspondingly with the decreasing displacement of the roller 4|. The supply of liquor in. the container 2| will be reduced to some point such as shown in Fig. 8, since a portion thereof is carried over into the vat 22 by the cure the desired dyeing. Since the leading end originally run onto the roller 4| from theroll 52 is immersed longer than the trailing end rolled thereon, the back and forth action between the n rgllers should always end after winding onto the roller 43 since this compensates the above effect,
as the trailing end becomes the leading end with respect to the roller 43. After the cloth has been run a suitable number of times, as described, the core of the roller 52 is replaced within the track l6, and the trailing end of the cloth is then run over the roller 50 and wrapped around the core. The shifting arm 5| is moved to neutral position so that both the rollers 4| and 43 may be idle. The brake strap at this time is hung over the pulley 80 on the roller 43. As the cloth is wet, it will adhere to the core 52. The lever 69 is shifted to rotate the roller 50 in a clockwise direction. As the core 52 rests upon the roller 50,
it will be rotated in a counterclockwise direction and will take up the clutch, unwinding it off the now brake retarded idling roller 43.
It will thus be seen that the cloth throughout the dyeing operation is always entirely submerged in the dyeing fluid-save for the small amount in passage over the roller 50. Consequently the time of operation of the dyeing processis substantially reduced since the absorptionof dye is a function of the time the cloth is exposed to the liquor. Furthermore, the oxidation of the dye materials by exposure to air is reduced to an insignificant quantity, giving a more even coloration and eliminating the waste of chemicals. The evenness of coloration is further aidedby the fact that, as the cloth is rolled onto one of the submerged rollers, a pocket between the on coming cloth and the roller is formed. This pocket catches and holds liquor that is squeezed directly through the cloth uniformly across the width thereof as it is wound onto the roll. This is in contra-distinction to the action of rolls suspended in the air, wherein, as previously described, the tendency of the squeezed liquor is to flow laterally toward the edges of the bolt. In the present device squeezing the liquid through the cloth causes superior impregnation, and more even distribution of the dye.
In addition to the above, the necessary quantity of chemicals is reduced. The peculiar shape of the vats, so as to employ the displacement of liquor caused by the increase in diameter of the rolls, reduces the required quantity of dyeing fluids to a minimum. Likewise in shifting from one vat to another, the overflow across the middle wall 26 saves in chemicals, since this overflow contributes to the quantity of dye available for a subsequent operation of rolling the cloth onto the other roll. In addition to this, dye may be passed from one vat to the other by operation of the valves 9|, 93, and. 95. Also, the rollers are extended substantially to the side walls of the device, the pockets 44 permitting the use of packing glands without in creasing the volume of'the vats.
As will be evident from the previous description, the interior of the vats is almost entirely smooth. Crevices and pockets are reduced to a minimum, the interior surface of the vats be-- ing entirely smooth and all of the working parts being on the outside. It will be observed that there are no frameworks or bearings within the vats where they would be subject to the destructive action of the dyestuffs, and also would involve the presence of many pockets and crevices. Crevices and the like, if present, will entrain quantities of dye material that in any event necessitate completely washing out the machine every time it is used. However, in most cases, these quantities of entrained dye elude the washing action and remain pocketed. Should the machine be used for a different color or a different shade, this entrained dye will gradually come forth and mix in indeterminate quantities with the mass of liquid within the vats, affecting the color of the dye and even causing streaks and specks in the material. This problem has been minimized by the construction and design of the present device, wherein crevices are eliminated.
.When it is desired to remove the rolls, the plates 32 may be unbolted, the bearings 49 removed and the rolls lifted out. The stufling boxes are likewise detachable, by removal of the screws 38.
The provision of the shifting bar 6! extending all the way around the machine is a factor both for convenience and safety. Obviously, it may be shifted from any side of the machine. Should the operator, when manipulating the cloth onto either roller 4| or 43, become entangled, he will be drawn against the bar and will shift and disengage the respective clutch. If he strikes the bar with sufficient force, he will not only dis engage the one clutch, but will engage the other clutch and reverse the action of the machine.
