Application led November 27, 1925. Serial No. 71,696.

*This invention pertains to apparatus useful in drying garments, rugs, textile fabrics of all sorts and is intended for `use in -laundries, drycleaning establishments, etc.,

it being equally adaptable to the'drying of clothes. that have been Washed or to drying'r and deodorizing of fabrics that have been cleaned by gasoline, benzine or the like.

Devices of this character usually comprise I a housing within which is arranged a foramvinous or perforated drum orbasket Within which the fabrics are placed and which is rotated or osoillated to tumble lthe garments about and thus togexpose.allportions thereofA to heated air. This tumbling of the garments produces a large amount of lint which sifts out of the drums `or baskets andtends 'to settleand collect Wherever a neighboring projection or a crevice produces an eddy or Y quiet zone in' the surrounding air. Usually heating devices, for-example steam coils, are arranged Within the `housing in close proximity to the drum and such heating coils afford many inaccessible places for ffthe lodgment of lint with resulting danger of iire and interference Withheat radiation from the coils and with the circulation of the air thereabout. Sparks or static electricity are frequently produced by friction in moving material orv contact lofjmetallic buttons etc., Within the drum and if any large .quantity of accumulated lint is present inthe apparatus av disastrous lire 'or explosion may and frequently does occur, such 4a danger being greater in cases When the lint is permeated with gasoline vapor or the like.

The casingr employed for housing the drum or basket is usually provided With thin Walls of sheet lmetal Which offer little resistance to the'passage of .heat from the interior of the structure so that a largel percent of the heatsupplied to the apparatus is radiated into the/Workroom. The temperature in the Work room is thus unduly increased, While from the heat standpoint the apparatus is extremely ineflicient.

The principal objects of the present invention are to provide apparatus of the class described in which the lint is delivered from the -d'rum into a-large and unobstructed settling chamber from which it may be removed frequently and Without difan independent source Outside of the housingv so that'tlie interior of the housing may be free from obstructions and so that oneA frequent cause of lire is eliminated; and to provide apparatusin -Which the heat supplied is employed economically and does not unduly raise the temperature ofthe Work room.`

.iFurther objects of my invention Willapy pear to those skilled in thev art from a reading of `the subjoined description in connectionwith the accompanying drawings Which are lto be considered as only illustrative of a preferred embodiment of my invention and 1n Vno Way as Vlimit-ing the scope thereof.'

-In the drawings;

Fig. 1 is a front elevationof my improved drying apparatus;

Fig. 2 is a transverse cross-section thereof; Fig. 3 is-,a longitudinal cross-section of the same; Y v j Fig. 4 is a transverse cross-sectional vieW of the drying tumbler drum; and

Fig. 5 isa detailed section. n l In the embodiment of my invention shown in the drawings, the Walls of the housing l comprise inner and outer sheathings 2 and. 3 With a space therebetween filled with any suitable heat insulating material 4V such as asbestos or the like. which extend to substantially the full height of the casing 1 -tit snugly so that When closed they make the casing practicallyairtight and When openedthey render practicallythe entireinterior thereof readily ac- The doors 6 and 7 ing 1 by a flared extension 15, While at the bottom of the casing is a longitudinal outlet pipe 17 which is preferably, considerably smaller in cross-sectional area than the inlet pipe. This pipe 17 extends in a substantially horizontal directionvthrough the lower part of the casing 1 at a substantial distance from its bottom and has the upwardly disposed intake lopenings 18 and 19
