The sloping section l6 termi nates at a heating chamber I 8, containing a 10 steam coil. I 9, into which the bath discharges, in its passage through the tub. The bath, after being heated by the coil i9, passes through a pipe 20 and is thence re-circulated, in the manner to be later described, through a flow box 2| which 15 is disposed above the bath at a point beneath the reel ll, so that the liquid is caused. to flow in the direction of travel of the material from the ?ow box 2|, through the bath, to the heating chamber it. A hood 22 encloses the entire‘ bath 20 and the reels so as to conserve heat and to pre vent escape of liquid or vapors. This hood is provided with windows 23 for the purpose set forth. The details of construction will be better un derstood by referring to Figures 1 and 2. In these ?gures, the tub Iii and'hood 22 are shown as supported by a framework comprising a plu . box and should be such as to provide a uniform discharge across the entire bath. Water is supplied when required to the bath by a suitable pipe 43 (Figures 5 and 6) which may terminate above the heating chamber l8. Water may also be introduced into the bottom of the tub . by pipes 44 which also serve as a drain when the tub is to be emptied. The pipes 44 are provided with valves 45 and communicate with a water supply pipe ‘6 controlled by ‘a valve 41 and with 10' a drain pipe 48 having a valve 49. By suitable actuation of the various valves, wash water can ._be admitted to the tub through the pipes 44 or the contents of the tub can _be drained through the drain pipe 48. 16 The dyestuil's and chemicals are supplied from a receiver 50, located at the side of the tub, and having a screen Ii. A plurality of pipes 52 and I! (Figure 1) of diil'erent capacities and having valves 54 and 55, respectively, are connected to feed the solution from the receiver 50 to the re circulation pipe 20. The valve 54 may be used for controlling the admission of dye liquid from this receiver, and the valve Si may be used to in troduce other chemicals which may be supplied to the pipe 20 at a more rapid rate. Other pipes of different sizes may be used or other means, such as differently sised ori?ces, may be used'to rality of uprights 25 by which the assembly is supported and joined by horizontal members' control the flow of liquid as desired, so that the 26, which support. the tub i0, and by horizontal rate of addition becomes a constant and is not members 2'! and 28 which strengthen the as dependent upon a variable valve adjustment. sembly and provide supports for- the hood 22. Obviously, water may also be introduced from The tub III is provided with a bottom ||, above _described, and with side members 30 which are the receiver 80, if desired. The pipes l2 and It may be connected to a ‘supported by the horizontal members 26. The pipe 2| leading from the heating chamber l8 discharge line It, having a draw-oil.’ valve II communicates with a pump section 32 (Figure 1) bath to be used for. mixing chemicals, and dyes having an impeller (not shown) therein, driven by a motor 32 which may be mounted above the level .of the bath on the outside of the tub (Fig ures 1', 3 and 4) andis connected to the impeller by a coupling mechanism 34. The ‘impeller is adapted to lift the liquid from the pipe 20 through a riser 35 ‘and to discharge the same through‘ a pipe 36 (Figure 4) into the ?ow box 2| ‘(Fig ures 5, 6 and 7). .The impeller is preferably designed to lift the liquid without agita tion and without introducing air therein so as to prevent deterioration of the bath. A standard type of impeller, capableof lifting the liquid with out applying centrifugal force may be used. . _ which provides means to draw water from the so that the total quantity of bath may be kept constant. A discharge pipe II, having a control valve ll, may be connected to the riser 3! to introduce re-circulated liquid-into the receiver 50 for use in ?ushing out the receiver, for as sisting in distributing the added dyestu?.’ through out the bath, or to provide liquid for mixing the dyestufl' or chemicals. This pipe 58 terminates short of the screen 5| so as to permit removal of said screen. / A discharge pipe ‘I, having a control valve 6|, may be connected to the pipe 28 to provide means for carrying away the wash water when washing upwardly from the pipes 44. Scum may be re moved .from the heating chamber I! by an over ?ow launder 62 (Figure 5) connected by a pipe 08 to the discharge pipe ‘I. The reels ii and I1 are supported by suitable The flow box 2| (Figure 5) is in the'form of an open-top box extending across the bath and is provided with a front plate 40, the bottom of which is shaped to form “a slot Ii, extending across the tub, through which the liquid dis charges to a lip 42 formed on the flow box 2| bearings (not shown) from the horizontal mem and terminating at the level of the bath.

The slot ll is shaped in accordance with the pressure distribution across the ?ow box 2i material from the tub at uniform rate. The so that a uniform distribution of liquid across speed of operation of the reels may be varied as the bath is obtained- It will be noted that the required.

The plates 61 are provided for guiding the material onto the reel l5 when the material is withdrawn from the bath directly onto this reel. 15 These plates are also slidable and are- provided with rows of holes 18 which are similar to the holes 89 in the plate 66. Two separate plates 81 are used because the space is not su?icient to permit sliding adjustment of one large plate. 20 to the reel I'l in'the manner above described; As The hood 22 comprises sides ‘II, ends 12 and a top 13, all of which are suitably supported by the framework. The windows 23 are mounted in doors 14 which slide in channels 15 located at the , ends 12 of the tub andare operated by suitable 25 hydraulic lifts, such as cylinders 18, mounted above the doors ‘[4, and having pistons (not shown) connected to rods ‘H which are attached at the lower part of the doors ‘I4. Fluid issup plied to the cylinders 16 by a pipe 18 controlled 30 by a two-way valve 19 connecting the pipe 18 to a supply pipe 80 or a discharge pipe 8|, The doors are sealed hydraulically by a hose 82 held in a channel 83 which surrounds the door opening and bears against the door around its 35 entire periphery when distended by ?uid pres sure, making possible the treatment of material 7 at temperatures above the boiling point and the retention‘of valuable vapors in certain processes. The hose 82 is connected to a suitable source of ?uid pressure (not shown), such as a water main or a compressed air line. When the seal is to be effected, the fluid is supplied to the hose 82 until it is expanded or distended to make a tight con tact around the entire door. When the pressure within the hose 82 is released, the door can be moved freely. Obviously, other types of seal may be used, particularly if a tight seal is not essen tial. A take-off reel 84 of any desired type, such as 50 a vacuum reel, may be positioned at one end of the tub and supported by an arm 85 attached to one of the uprights 25. This reel may be used for removing the batch of material from the tub and at the same time extracting excess water 55 therefrom. One or more longitudinal partitions (not shown) may be provided in the tub so as to divide the same into two or more compartments, which may be used separately or together de-' pending upon the size of the batch being treated. 60 Side bars 86 (Figure 6) are provided to keep the material out of contact with the sides of the tub. A conveyor belt or chain 81, carrying samples of the material, is mounted above the heating chamber I8 and is driven by a belt 88 from the reel II. This belt 81 dips in the bath and re , ceives treatment similar to that .of the material on the reels [5 and H. The door 14 is provided with a port 89 through which‘ the belt 81 may be viewed and which may be opened to‘ permit re moval of samples for observation or test. In the operation of this device, the dye solu tion is prepared at the proper concentration and temperature according to the requirements and is circulated through the bath while the material is being passed therethrough from the reel l5 by mixing the dye solution in the receiver 58 and 10 introducing the same into the pipe 20 by suitable actuation of the valves 54 and 55. In this way, the dye is thoroughly dispersed in a large volume of solution before it is introduced into the tub, so that the dye cannot contact the material in a 15 concentrated form. The rate of addition of the dye can be adjusted with respect to the rate of circulation of the liquid and the number of rev olutions of the reel so that a suitable distribution is obtained. Furthermore, the flow box 2| holds 20 a substantial quantity of liquid and provides a further opportunity for the dye to be thoroughly dispersed in the liquid before it is s‘uppTied to the bath. ' The ?ow of liquid through the tub assists in 25 the removal of impurities, such as lint, lime soaps, etc. into the heating chamber, where they are removed by the launder. Since the tub is shaped to conform to the path of the material, the amount of excess dye bath 30 is reduced to a minimum. The cost for dyestuffs and chemicals and the cost of heating the same are correspondingly reduced. Furthermore, the maintenance of a uniform temperature through out the bath eliminates local variations in tem perature which occur when the bath is heated without forced circulation. This permits an ac-_ curate control of the dyeing conditions and re duces the possibility of injuring the material or dyestuffs by improper temperatures. By suitable adjustment of the operating char acteristics, the dye may be added at a rate de termined by the speed of travel of the material through the tub. In this way, an accurate con trol of the color and condition of the material may be obtained. The washing of the material is facilitated be cause the water may be introduced by the pipes 44 and caused to ?ow with the'material, thence into the heating chamber l8, whence it is re moved through the pipe 60 or it may be intro-I ‘ duced into the tub by the pipe 43 and caused to ?ow in a reverse direction and out through the pipes 44 and 48 for ?ushing out the .tub and washing the material. By providing the various controls, including the receiver 50, on the out side of the machine, the dyestu?'s or chemicals may be mixed and introduced when the tub is operating without opening the hood or otherwise interfering with the continuous operation of the dyeing process. During the run, samples may be taken from the belt 8'! without stopping the machine. When it is desired to raise the doors 14, the hose 82 is first collapsed by releasing the ?uid therein and the valve 19 is actuated to supply ?uid pressure to the-cylinders 16. The bath is then accessible for adjustment or for inserting or removing the material. When the doors are closed and sealed, escape of vapor or fumes is prevented and the 70 atmosphere of the dye house is kept free from mist. , I have found that some dyeing operations are a-function of the speed of the material. By clos ing the doors ‘I4, I am able to run the material 75 4 2,188,828 . at a high speed, it necessary, without throwing _ liquid from the tub. This is of particular im portance with some kinds of materialr By washing the material in the normal direc tion of ?ow, the impurities are removed to the launder and are prevented from contaminating the material and necessitating subsequent clean ing. The scum is removed continuously by the launder 62 and pipe 83. A screen may be mount ed above the heating coil IO, ii desired, to prevent ‘ impurities from being re-circulated. It is ‘to be understood that the heating cham ber may be at a higher level than the flow box to obtain gravity ?ow oi liquid, in which case . a pump may be used to raise the liquid from the bath to the heating chamber.
