DYE-TUB APPARATUS.

of dyeing apparatus in which a vat is employed in conjunction with driving and conveyer rollers.

The invention has special reference to dyeing apparat-us which is employed in the dyeing of textile fabrics and especially in' the form of strips, bands or sheets, and has for its object to accomplish a uniform dyeing of the materiall from end to end and from side to side. Great diiculty has been experienced hitherto in dyeing fabric uniformly on account of the strength of the dye bath varying during the operation of dyeing.

Another obj ect ofthe invention is to over- A come this difficulty by means -of which constant strength of the dye bath. is practically assured.

Another object of the invention is to apply the dyeing liquid to the fabric in such a manner as to produce a uniform acti-on on every part of the goods.

Another object of the invention is to recover the water used for power 4for the purpose of washing the goods.

Another object of the invention isto utilize the condensation of the steam used in heating the dye bath-for power.

Another object of the invention is to provide an improved dye tub apparatus means of which goods may be removed from the tub without loss of time. A

the gates. Fig. 6 is an enlarged view, in cross section, on the line y-g/, Fig. 3, dis- Figs. 7 and 8 are detail views yof the means for disconnecting the driving rollers from the operating mechanism. Fig. 9 is an end view of the apparatus. Fig. 10 is a detail view in perspective showing the branch pipe utilized in washing the goods. Fig. 11 is a detail view of a portion of one ofthe conveyer rollers and its pivotal support at one end of the Fig.v l2 is a detail view showing a portion of the operating mechanism.

In carrying out the invention,-'I provide a vat 1, preferably having metallic ends 2, wooden sides 3, and a wooden bottom 4e, with an outlet 3 and stopper 4', said metallic ends being secured to the wooden sides and bottom by means of a flange. 5 and bolts 6 extending through j said tiange 5 and the wooden sides and bottom and through a metallic strip I7, which strengthens and reinforces the vat. The sides 3 are secured to the bottom 4 by bolts 8 extending fro-1n top to bottom of the sides.

- Any suitable mechanism may be employed for operating the driving rollers of the apparatus, and as here shown in Fig. 6 a water motor 9.is employed mounted in a casing 10 supported on a shelf or extension 11 of one of the met-allie ends of the tub, said shelf being braced bv brackets 12 secured to the metallic ends o-f the tub. In conjunction with the water motor .an operating mechanism is employed mounted in a casing 13 on the shelf 11'` and in end casings 14the shaft 15 :of the water motor having on its end a worm gear 1,6 meshing with a worm wheel 17 mounted on la shaft 18 which is connected to a shaft 18 by a locking joint hereinafter described.

vThe shafts 18 and 18, extend through the ends of the casing 13 and each has on its outer end a beveled gear wheel 19 meshing. with a beveled gear wheel 20, said beveled;

gear wheel 20 being mounted on a shaft 22 slidably connected therewith, as hereinafterdescribed, which shaft 22 is provided at its outer end with a knob or handle 23, the inner. end of said shaft 22 being detach .bly connected to the shaft of the driving roller by means of a coupling joint formed of the two interlocking parts 24 and 25, the part '25 being on the outer end of the `bearing spindle 26 of the shaft 27 and projecting from the driving roller 28, the spindles 26 of the shafts 27 ofthe driving rollers detachably resting in vertical U-shaped seats or bearings 29. The beveled gear wheel 20 is held from turning on its shaft 22 by means ofsa spline 30 which enables the shaft 22 to be moved longitudinally through thecasing 19 by means of the knob or handle 23, to engage or disengage the shaft 22 from the shaft of the driving roller 28. It will be seen that by means of this construction the driving rollers may be disconnected from the operating rmechanism and lifted out of their bearings when it is necessary to remove them. The shaft 18 and beveled gears 19 and 20 may be' disengaged from the worm 'wheel 17 by means of the coupling joint 31, and a lever handle 32 projecting up through the casing 13.

Water may be supplied' to the'water motor 13'by means of a pipe 33 connected with the motor and controlled by a valve 34. The motor may be driven by means of the water of condensation of the steam which is passed through a heating coil located in the bottom of the vat, the water of condensation flowing from said coil primarily and secondarily when the water of condensation has been emptied from the coil by the eX- haust from said coil.

.Thepipe for heating the dye yliquid consists of a steam pipe 35 which enters the vat-at the end opposite to the motor and entends over the bottom of the vat in folds. or convolutions, said pipe 35 passing out the other end of the vat and connecting with the-motor through the pipe 33, the passage of water to the pipe 33 being controlled by a valve 36. The steam being admitted at one end ofthe vat through the pipe 35 and passing through the convolutions or coils, which extend through the cold dye over the bottom'of the dyevat, is condensed thereby and is then conveyed directly to the motor, the valve 34 being closed and the valve 36 being open. As the motor 13 operates, the water is discharged therefrom through a tapering discharge passageway 37 to which is connected, by means of a coupling 38, branch pipes 39 having end portions 40 which project through the end of the vat into the same, and which are utilized for washing fabric. Said coupling 38 is also provided with a discharge pipe 41 through which the waste water may be carried olf to a sewer or. other place of discharge.

The iow -of liquid through the branch l pipes 39 and 41 is controlled bya valve 42 operated by means of a thumb nut or handle 43 so that when it is desired to use branch pipes 39 and 40kto convey water to wash the goods in the vat, the pipe 41 is closedf by meansof said valve 42, which also serves to close the branch pipes 39 when desired to permit the water discharged from the motor to pass oft' through the waste pipe 41. By e means of the main supply pipe 33 with its controlling valve 34 and the steam pipe 35 with its controlling valve 36, either the water of condensation from the steam'may be utilized to drive the motor 13, the valve 36 being open and the valve 34 closed; or else by closing the valve 36, the motor 13 may be driven by Water passing through the main supply pipe 33, the valve 34 being open. The steam is admitted in one end of the coil, and as it passes through the coil, which is in direct contact with the cold dye, condenses and is then conveyed directly to the motor, for the purpose of furnishing power; or may be conveyed to a reservoir or storage tank thereby storing up a supply of water, which may then be conveyed to the motor or various motors which may be employed throughout the dye house. By means of this utilization of the water of condensation in the steam pipe or by means of the Water from the main supply pipe, a battery of four tubs or vats may be driven with one motor, the power from the motor being transmitted to the driving rollers and thc other vats by means of alined shafts and suitable gears.

In addition to the driving rollers 28 which are mounted on the top of the ends of the vat, conveyer rollers 43 are employed having their bearings in the ends of the vat and located toward the top of the vat and adjacent to its sides, and other conveyer rollers 44 are located adjacent to the bottom of the vat and at a distance from its sides with their bearings mounted in the ends of the vat. The fabric 45 is mounted, as shown, on the driving rollers 28 and extends downward over the tubular rod 46 which, adjacent to its ends,.is mounted on transverse rods 47 projecting through a post 48 and extending to the sides of the ends 2, said y rod 46 being held in yielding position by means of a spring 49 against the fabric 45. The fabric y45 extends down over the rollers 43 and 44 when it is yto be washed, as shown in dotted lines in Fig. 6.

As shown in Fig. 6, the branch pipes 40 project into the vat through one end thereof, each above a conveyer roller 43, and, in conjunction therewith gates 50 4are em-` ployed, which consist of longitudinal strips of metal extending from end to end of the vat and hinged by means of rodsv51 having their ends mounted in the end of the vat at each side of the branch pipe 40. Both of said gates bear against the roller 43, the fabric 45 passing between' one of said gates and the roller 43. It will be seen that by means of this arrangement a discharge of water passing out of the branch pipes 40 is discharged between the gates 50 onto the fabric as it passes over the rollers 43. `Oneshown in Fig. 9 by means of an arm 52 on I `one end of the vatr and held up against a .lll

stop pin 53 by means of a spring 54 connected to the arm 52 atr one end and at its other end to the rod 47. f

In order to retain the driving rollers 28 in position, their shafts are each provided at one end with a grooved .pulleyr 28', over which extendsa looped cord 29', the loop 29 depending from`the roller 28 and having suspended therefrom by means of a hook 30 or other suitable device, a weight 31, as shown in Fig. 9. By this means the shaft of the roller 28 will be prevented from jumping out of its bearings. Y r In order to overcome the diticulty of uneven dyeing, I employ an endless belt 55 of material that has great absorbing power, said belt extending over and depending from a roller 56 centrally located in the vat at a little distance from the surface ofthe liquid dye 57 with its bearings in the metallic ends of the vat, said belt being of suitable width and of a length adapting it to depend in and be partly immersed in the liquid dye 57, as shown in Fig. 6.

As shown in Fig. 6, the fabric 45 passes down over one of the conveyer rollers 43 and then over the conveyer roller 56 and bearing upon the belt 55 and then over the other conveyer roller 43 and up .to theother vdriving roller 28. Owing to the pressure of the fabric upon the endless belt 55, there will be sufficient friction to cause the belt 55 .and its roller 56 to rotate, thereby conveying a constant supply of dye from the bath to the fabric, the fabric coming in direct contact with the absorbing belt 55 so as to dye conveniently from side to side and from end to end.

By means of this device, no other tank or vat is necessary to prepare or mix the dye in as the dye may be mixed in the same yat in which the goods are placed.

Hitherto, at ithe beginning of the operation of dyeing, the fabric is rolled on a Wooden roller on a separate machine` for that purpose; it is then placed on a shaft which is mounted in a pair of open hearings some distance above the open bearings 29 at the "ends of the vat, and then is rolled off on one of the top rollers 28 which have hitherto been stationary on the vat before it can be dyed, which takes up considerable time. When the goods have been dyed and washed,

the same process must be` gone through before the fabric can be removed from the tub, which likewise consumes a great amount of time. I

Referring to Fig. 2, the shaft 27 of the driving roller 28 is provided with a notch 58 which is engaged by means of a spring catch 59 mounted in a recess 60 on the roller 28. By means of this device, the shaft will be held against longitudinal movement. The

vin the steam goods may be rolled up on this improved roller and placed directly on the dye tub shaft ready for the process of dyeing, theredischarge passageway from said motor, branch dischargepipes extending from said passageway and projecting into the vat, and a steam pipe entering the vat, extending in undulations over the bot-tom of the vat, and pass-ing out of the vattto the main supply 0f the motor.
