f omo JULIUs cremeren, or NEUsrADr-oN-.THE-HRDT, GERMANY APPABATUFOR THE FLUID TREATMENT F TEXTILE Application led February 21, 1929, Serial No. 341,678, and 'in Germany August 31, 1928.

In the fluid treatment of textile bers for the washing, bleaching, dyeing and the like operations, the common practice of. packing the fibers in a mass in a treatment receptacle and the removal therefrom for hydro-extracting after each liquid treatment consumes much time and the handling and method of treatment is liable to cause patchy dyeing or bleaching. The object of the present in- ,l vention is to provide means whereby textile fibers may be treated with any fluid oi` with -a series of fluids for the washing, bleaching, dyeing or the like Awith desired intervening hydro-extracting, without, handling or removal of the fibers from the position in which they were first placed within a treatment vessel.

With this object in view the treatment receptacle consists of a casing which is adapted to receive ina convenientform of packing the fibers-which may be short laps, or cotton raw stock, or be in any other form of preparation for the purpose-this receptacle having admission and emission means for fluid and having tted thereon an outer casing. The receptacle may thus serve as afluid treatment means f or the fibers andthe outer seating allows of such receptacle being placed in a treatment vessel for' any desired liquor treatment, with subsequent removal of' thesaid receptacle from the vessel and placing thereof 'in a hydrofextractor as a single unit, no unpacking or handling of the charge of fibers being necessary. The emission means for the fluid serve as part of the necessary channel for the uid circulation through the fibersduring treatment, and also as emission points for superfluousiiuid when the receptacle is placed ina hydro-extractor, the fluid being led away from'the extractor as usual.

The accompanying drawings show a very convenient form of carrying the invention into effect by way of example as to arrangement of mechanical details and the invention will now be described with reference to these drawings wherein:-

Figure 1 is apsection of the receptacle in position in a liquid treatment vessel, for instance a dyeing kieryFigure 2 is adetail to L a larger scale showing a means for mounting the fiber. packages in the receptacle; l and Figure 3 1s a section of the receptacle in position in a hydro-extractor.

Referring to Figure 1 and when necessary to Figure 2, 4 is the outer casing wall of the circular receptacle; 5 agbase therefor having formed centrally thereof a conical tubular seating 6, and 7 a central casing of metal having incorporated therewith a cover 8 which l in this space are the mountings for a' plu-` rality of fiber packages a; Figure 2. Referring to Figure 2 and also to Figure 1, the ends of perforated tubes 15 are secured in the casing Wall 4 by means of threaded nipples 16. These perforated tubes serve as the mountings for the fiber packages, and to mount the latter they are woundor placed on perforated tubes 17 Figure 2 adapted to slide over the tubes 15. There is provided at each package bearing point in the receptacle an end flange 18 with a boss 19 which lits within the nipple 16 and each tube 17 has an end flange 20 having the closed boss 21 bearing a spring member 22, which takes into the end of a perforated tube 15. By merely sliding the package w and tube 17 into position therefore the said package is firmly held.

In operation all the tubes 17 being charged' with their fiber packages @the cover 8 of the casing 7 is removed and the` tubes 17 placed in position as seen in Figure 1. The cover is then closed and secured in that position. The receptacle`4 is then placed in a treatment vessel 23 having the circular wall 24 Figure 1 and the movable cover 25, the

seating 6 of the receptacle fitting upon a conical pedestal 26 within the vessel. The conicalpedestal is hollow and is formed with the orifices 27. A rotary pump 28 supplies under pressure the desired treatment fluidwash water, bleaching or dyeing liquor, or steam for steaming purposesthe liquld passing as shown by the arrows into the pedestal 26 through orifices 27 into the annular space This direction of flow of fluid may be reversed.

The treatment being finished, the cover 25 of the vessel 23 is removed andthe receptacle lifted out. It is then placed in a hydro-extractor 29 Figure 3 which may be of known form and ris fitted with the central cone bearing 30, on a pedestal 31, with a. driving pulley o n its central shaft 33, and means for driving the shaft as shown in broken lines. The cone 30 of the hydro-extractor 29 receives the tubular seating 6 of the casing 4,- and the rod 11 serves to secure the latter in position if desired by the thread on the lower end thereof engaging in a tapped hole central of the upper end of cone member 30. The whole receptacle isnow Whizzed, and superfluous liquid is ejected from the package by way of the tubes 15 and 17into the extractor casing 23 and flows thence by the outlet 34.

The treatment of small fiber packages is advantageous as the usual method of treating a large fiber mass involves a high degree of pressure-or vacuum where vacuum is employed in the liquid treatmentwith unevenness of treatment, as the pressure or suction is greatest at the fluid inletsor outlets. The provision of the central casing 7 directs the liquid to the fiber packages and moreover chemicals and dyestuffs are saved in the complete treatment, as a smaller volume of fluid isnecessary than would be the case if this central space were left vacant to be filled with fluid. Nevertheless it will be understood that, especially for small quantities of textile bers, the provision of of outlets such as shown at1 the nipples 16, combined with the receptacle seating 6, would serve my purpose, and are deemed to be included in the appendedjclaims. Such a construction will be well understood without il;4 lustration as it involves merely the removal of the tubes 15 from the construction of Figure 1;

As a receptacle for the treatment with fluids of -fiber packages under pressure,`a casing and removable cover therefor, a plurality of perforated tubes forming mountings for fiber packages each such tube being fittedto the casing wall and opening to the exterior thereof, each tube bearing flanges one of which is removably held thereon, and an outer flangevconstituting a seating and fluid admission means upon the casing.

2. As a receptacle for the treatment of fiber packages with fluids under pressure a casing and removable Cover therefor, mountings therewithin for a plurality of fiber packages. each such mounting being' tubular and a sullicient qu antity means at the lower end of such casing, and a central casing within the receptacle, forming' with the outer casing wall an annular space vwherein the fiber package .mountings are situated, such annular space being open to the fluid admission means. Y

3. As a receptacle for the treatment with fluids of fiber packages under pressure, a casing and removable cover therefor, a plurality of perforated tubes forming mountings for fiber packages each such tube being fitted to the casing wall and opening to the exterior thereof, an outer flange constituting a seating and fluid admission means upon the casing, and a central casingy within the receptacle forming with the outer casing wall an annular space wherein the perforated tubes are mounted, such annular space being open to the fluidadmission means.

In testimony whereof I have hereunto set my hand.
