To all whom, it may concern.-

Be it known that I, PAUL SCHIRP, a citizen of the GermanEmpire, residing at Barmen, in the Province of Rhenish Prussia and Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Dyeing, Bleaching, Washing, and otherwise Treating Textile Materials; and I do hereby decla-re the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use same.

This invention relates to improvements inapparatus for dyeing, bleaching, treating with mordants,washing, and otherwise treating textile materials, and in which the liquid is forced through the apparatus in a circulating circuit. From known apparatus of this class my new apparatus, however, distinguishes itself by this, that the receptacle containing the material to be treated,and which in the following Ishall call tub, is mounted upon a frame which allows the same to be raised out of or sunk into the receptacle con taining the liquid,called in the following the vat, and that when it is raised out of this latter receptacle it can be transported or carried away from the same. This arrangement has the following advantages: The material to be treated can be more conveniently filled into the tub and taken out of it again, and it can be sunk or plunged into the vat in a reversed waythat is to say, with the close bottom above and the open side below, and thereby covering the fluid,` so that the admission of air is excluded from the goods during the dyeing or -other process where such is desirable, arrangements being pro-` vided so that the tub when raised above the vat and drawn away from it can be turned on horizontal pivots upon which it is suspended.

On the accompanying drawings the new dyeing apparatus it shown in various views and sections.

Figure 1 is a vertical section along line I I of Fig. 2. Fig. 2 is a view in plan of Fig. 1. Fig. 3 is a side view showing the tub raised out of the vat and drawn away from it. Fig. 4 is'a view at right angles to Fig. 3, partly in section and with the tub partly sunk into the vat.

.opening The tub 1 consists of a rectangular prismatical box which is supported on a frame 2 3 4 in such a manner that it can be drawn away from the vat 5, raised or lowered, and also turned around on horizontal gudgeons or horizontal pins 9, fixed to it. In order to be able to raise and lower the tub, the pins 9,

.supporting the same, are carried in the upper forked part 8 of therpistons 7 of a hydraulic lifting device consisting of the pressure-cylinders 6, bolted to the girders 4 of the frame and into both of which water under high pressure can be let by pipes 6 simultaneously, by which the pistons 7 are raised. These pistons are guided in the girder 2 of the frame. The frame 2 3 4 is mounted on rollers 4, which run on rails 4b.

. The turning of the tub is done by means of a crank l2 and a spur-wheel and pinion 10 11, keyed to the pin 9 and a 'spindle lla, respectively, the latter being carried in a side bracket 11b of the piston 7. A ratchet-wheel 14 on the crank-axle 11L and a claw l5 fix the tub in any height and prevent its arbitrary lowering by its own weight.

The two opposite sides 1S 19 of the tub form removable covers provided with chamfered edges 20, fitting to corresponding beveled edges 21 on the sides of the tub themselves, so that whenthe fastening-screws 22 are screwed tight the tub will be hermetically closed, because also in every other respect it is so constructed that the entrance of air can be excluded. Thereare openings 24 in the bottom 33 along the sides 18 19; but these, as well as the two other sides, are prolonged below the bottom 33, so that when the tub is lowered into the fluid these prolongations forma hydraulic or hermetical closure. The said openings 24 can be regulated in Width by throttle-valves 2,5, actuated by levers 26, which can be xed Vat any desired width of by a quadrant 28 and a bolt 27.

In the interior of the tub there are perforated walls or diaphragms 29 30, parallel to the covers 18 19, forming a central chamber 3l. This chamber communicates by a boring in the gudgeon 16 with the flexible pipe 17,coming from the pump 17a. On both sides of the chamber 31 there is a space 32, into which the material to be dyed is placed. Perforated false bottoms 33 are placed between ICO the material and the covers 18 19, which. can be pressed upon the material by springs 34, so that hollow spaces 35 are formed, which communicate at their lower end with the vat 5 by the openings 24 and through which the fluid streamingout of the material is returned into said vat 5.

Peep-glasses 36 are fixed to the covers 18 19, so that the circulation and the condition of the circulating dyeing fluid can be observed, allowing a conclusion as to the state of the dyeing operation.

The working of this apparatus is as follows: For filling and emptying the tub it is raised out of the vat and turned so that the covers 18 19 form the top and bottom sides. It is then drawn away from the vat and lowered again. The covers 18 and 19, respectively, are then taken off and also the false perforated bottoms 34, when either of the said operations can be carried out. When one of the spaces 32 is filled and the respective 'false bottom 34 is put upon the material, the cover 18 or 19 is screwed tight. Then the tub is raised and then carried over the basin, and it is then turned and lowered and brought in the position shown in Figs. 1 and 4, but of course as deep down as possible, and in any case so deep that the bottom edges ofthe side walls are completely immersed into the dyeing liquid. Now the pump is set to workand forces the liquid into the chamber 31, from which after this has been completely filled the fluid is forced through the perforations in the false bottoms 29 30 and flows uniformly through the material to be dyed, coloring the same equally in all its parts,and by the spaces 3.4 and the openings 24 it flows back into the basin 5. If it should happen that the color or the appearance of the liquid as seen by the peep-glasses is different at both sides, this would indicate that the coloring or dyeing effect is not equal on both sides of the chamber. Then the flow of theliquid through the material must and can be regulated by the throttle-valves.

The dyeing apparatus shown and described has the great advantage that besides the possibility of regulating the stream of the liquid pressed through the same the fluid need not be lifted high, because the tub 1 is immersed into the vat 5, the tub covering the vat nearly completely. There is very little evaporation and cooling of the liquid. Its peculiar construction allows absolute exclusion of airfrom the dyeing material while the dyeing is going on. The filling and emptying of new and finished material, respectively, is most convenient, because the tub can be Withdrawn from the vat and lowered into the most convenient position for these operations.

Having thus described my invention, I declaro that what I desire to be secured by Letters Patent is- 1. In an apparatus for dyeing, bleaching,

washing and otherwise treating textile materials by liquids in combination with a fixed vat containing the liquid, a tub 1 containing the material to be treated with the liquid, said tub being supported on a'lifting apparatus capable of lowering the same into basin or raising it out of it, `while the lifting-gear itself is carried` on a frame 2, 3, 4 on wheels 4LL for the purpose of withdrawing the raised tub together with the lifting-gear away from the basin l, as described and illustrated.

2. In a combination with the tub 1 a frame 2, 3, 4, 4, pressure-cylinders 6 fixed on girders 4 of said frame, pistons 7 in said cylinders, forked bearings 8 formed at the top of pistons 7 to carry the tub l on pins 9 projecting from two opposite sides of the tub, a bracket 11b extending from the side of one of the pistons 7, a spindle 11 carried in said bracket, a spur-wheel 10 keyed to the end of pin 9 and gearing into a pinion 11 on spindle l1, a crank 12 at the end of spindle 11, a pipe 6 leading into the pressure-cylinders G, the whole as described and illustrated an d for the purpose set forth.

3. In an apparatus for dyeing, bleaching, washing and otherwise treating textile materials by liquids in combination with a basin 5, a pump 17, a flexible tube 17 and a movable tub 1, said tube 17 being connected at one end to the boring of a gudgeon 16 leading into the interior of said tub the whole as described and illustrated and for the purpose set forth.

4. In an apparatus for "dyeing, bleaching, Washing and otherwise treating textile material with liquids, in combination with a tub 1 perforated diaphragms 29, 30 in the middle of the same and forming a chamber 31 between them for introducing the liquid therein and free spaces 32r at both sides of this chamber, false perforated covers 32 for each of these spaces, closing-covers 18, 19, peepglasses 36 fitted insaid covers 18, 19 respectively, bevels 2O along the edges of' said covers tting to corresponding bevels 21 along the respective edges of the tub 1, fasteningscrews 22 for pulling the covers 18, 19 tight against the edges of the tub, the whole as described and illustrated andfor the purpose set forth.

5. In combination with the tub 1 having outlets 24 between the bottom 33 and the covers 18 and 19, the throttle-valves 25 actuated by levers 26, bolts 27 and quadrants 28, for regulating the Width of the outlet of the liquid from the tub back into the vat, the whole as described and illustrated.

In testimony whereof I have aflxed my signature in presence of two witnesses.

PAUL SCHIRP.
