QlEFICEQ ADOLF BSLEG, (33f RURSCHAOH, SVFITZTEFZJLANED.

Application To all wlzcm it may concc'm:

Be it known that 1, Bloom BOLEG, engineer, 2i subject of W'iii-temhei'g, Germany, and 110W residing at L0. 9 Bur-:gstrasse, Rorschach, Switzerland have invented new and useful Improvements in Methccis of ancl Apparatus for Drying llextile and ether Mziierials, of which the following is specification. I

Textile fabrics, such new-eel cotton rim the like, are generally {hi by mews of Warm air, which is forceil c1" drawn through such materiel.

Wet meter W1 The circumstance that the same iii all i the current cit e12: has to peneerz te n'mtcrial between lies; and the sec-0nd. source 0i heat only vc This method very fir/arable icthe 7 h. is caused to travel in I whole of the Wetmaterial a current of air which is highly heated by two sources ofheat and is consequently very capabldof absorbing moisture. The material being dried is then further conveyed in layers in the direction of the current of air. The progressive drying cannot injure the material, as it is effected by the air which has been already cooled and moistened by the wet layers of material.

,The material to be dried is fed in the direction of the current of air as long as the air, which is gradually becoming cooler, can absorb moisture. When the current of air a saturated with moisture, thatis to say, pent, the material is withdrawn from the action thereof, but is then immediately exposed to its influence again at the place at which it is only heated by one source of heat, being conveyed in counter-direction to it in layers, and then again withdrawn as soon as the drying is ended. The completion of the drying is thus effected in accordance. with the economical counter-current system, but the injurious action of the latter process on the color and spinning capacity of the material is obviated, as in conse uence of the division of the total source heat, only moderately heated air is applied.

Apparatus suitablefor drying according to my new pr ample, in the accompanying drawing, in which Figure 1 is a vertical section, and Fig. 2 a horizontal section.

A heating chamber a, a drying chamber 6, a heating chamber a, and a drying cham ber d are arranged adj acently to one another. The heating chambers a and 0 are furnished with heating devices e, and in the drying chambers b and d superposed openwork or erforated receptacles f are provided. The

eating chamber a communlcates with the drying chamber 6, by means of openings 9, while the heating chamber a communicates with the drying chambersf-b and (1, through the openings 71, and 2'. Moreover, an opening that is closed by a folding door or flap is is. provided in the partition between the heating chamber 0 and the drying cham- 55 ber'd. 1 v v The current of air flows through the heating and the dryingchambers in the direction indicated by the broken lines along which arrows are shown.

The dryin chambers b and a? are provided with oors l and m, through which the lowest receptacle f can be'withdrawn from the chamber 5 and after bein J wheeled on the trucli n in front of the cham- 65 her d and introduced into the latter,

ocess is shown, by way of'ex- The receptacles f can be moved collectively downward in one chamber 6 and upward in the chamber d by means of any ordinaryactuating mechanism suitable for the purpose. 1

The uppermost receptacle f in the cham ber (Z can be introduced into the chamber 6 through the door by means of a suitable device, such, for example, as an endless chain.

The complete course or circuit, as it were, traversed by the receptacles f is indicated by the full lines in which arrows apear.

p The action of the apparatus is. as follows: In the course of the continuous drying o oration the material which is most neary dry is contained in the bottom receptacle f in the chamber 6. When this material is thoroughly dry, the bottom receptacle f is taken out of the chamber 6 through the door land placed on to the truck n. The mechanism for operating the receptacles f now comes into action, raises the receptacles in the chamber d all to ether throu h a distance equal to the heig tof one oft em, and introduces the top one into the chamber 6. l-Iereupon the receptacles f in the chamber 6 are lowered 'throu gh a distance equal to the height of one of them.

Meanwhile, the

dried material is removed from the recep- 95 tacle f that is standing on the truck 01., and wet material placed in this receptacle. The truck n is now wheeled in front of the chamber d and the receptacle f filled with wet material thereupon pushed into the chamber at through the door m. The truck is then wheeled back in front of the chamber 6 again, from which the now lowermost receptacle 7", containing dry material, is removed, and so on. Thus in the chamber 7), which is heated by a single source of heat, the drying-air flows in a contrary direction to that of travel of the material being treated, while in the chamber of, which is heated by two sources otheat, the air flows in the same direction that in which the material being dried is traveling.

My new method is very favorable 'for the aterial -to be dried, fully utilizes the dryg capacity ofthe air, and consumes but little steam, and the apparatus employed incarrying it out need have only two drying I chambers. The im roved method, therefore, combines all the a vantages of the countercurrent and the graduated processes, without having any of the defects of those two methods. 1

Having thus described my invention, I declare Chat what I claim as new and desire to secure by Letters Patent is:

1. Apparatus for drying textile and other materials, comprising two heating and two drying chambers arranged in alternation with/each other and all in communication,- 1 and means for'feeding the material in suc- 1 0 a in session thmu 'h said inleis from the heating chambers 10 the dry-- inguinnnlrers are situated at the opposite em!
