Application filed Qctober 27, 1927. Serial No. 229,212.

This invention relates to drying apparatus.

and more particularly to a drying apparatus.

intended for use in hotels, apartment houses and the like for drying the shoes of the c- 5 cupants or visitors which have been partially or wholly wet through due to exposure to rain, snowor other moisture. It may alsobe used wherever it is desired to dry moisture from shoes-and similar articles- Among the objects of the invention are to provide a device which will quickly and efiiciently dryboots, shoes and similar-objects;

- to provide a device in which shoes may be dried by the application of heat to the interior thereof; to provide a device of this character which is simple, cheap and eflic'ient in operation; and generally to improve the art of evaporating any liquid from theshoes and other like objects either during the proces s of manufacture or afterward.

Other objects and advantages of the invention will be apparent from a reading of the following specification and subjoined claims when taken inconnection with the accom panying drawings,in which: Figure 1 is an elevation partly in vertical section of my device;

Fig. 2 is a section taken substantially on the line 2-2 in Fig. 1; and

Fig. 3. is a fragmentary seetionsimilar to Fig. 2 but showing a device. r

. I have found that it ismo r'e' eflicient to dry shoes by forcing the heated air used fordrying into the interior of the shoe'than subjecting the shoe to external heat, an. air blast or both. 1 This is due; in;the event that the moisture has enetrated to the inside of the shoe, to the act that external heat will 40 not evaporate the water from the inside to;

any material extent; and. in the event that the moisture has only partially penetrated I the material of theshoe, to the fact that if the drying is done from the outside, the sur face of the .leather dried first forminga relatively hard and substantially water-impervious skin which prevents the evapora-.

tion of water through the outside, 'the re- 7 sult being that if ,the shoe is dried out at all, the Water must pass completely through the leatherand out the inside of theshoe, this action resulting in a complete saturation for a time at least, of the entire thickness 0 theleather in the shoe, so that when it .is

modified form of the dried, the shoe is non-pliableand extremely again lilnbered up. By the use of my 55. uncomfortable to the wearer until- -it has been method, the heat is applied from the'inside H which "in the case under consideration is dr so that the water is evaporated through t e substantially liable-condition by the avoid- 6d outside of the shoe, leaving the leather in a' ance of the 's in effect above referred to; I

To .accomplishtheabove described results, I

#1 preferably make use of a means, such as a fan'blower, f0r forcing air in the desired direction, an ainheating' means and"suitahle air-conducting means for directing the heated air into't-he interior, of the shoe.

the accompanyingdrawings I have shown a device embodying my invention for carrying out the drying in a quick, cheap and efli'cient manner; i

Referring to-Figs. 1 and '2, Iemploy a cabinet generally indicated at 1 having suitable doors 2 to give accessito the interior thereof and havin' a artition 3'se arating the top chamber or air header 4 our the lower or drying chamber 5; Anydesired means such as a centrifugal fan blower 6 may be employed to force air into the chamber 4 preferably through anopening 7 in one end, the blower being driven by anysuitable I source of power, such as the electricmotor 8.

I- employ-anysuitable form ofair heating means, su'r'zhas an electric resistance unit 9, preferably located within the air header 4,

but it is to be understood that steam coils,v gas or coal burning devices and various other sources of heat may bensed if desired.

For the purpose of conducting theheated air from theheaderA into the shoe drying compartment 5, I employa' plurality of tubes or dupts 10 suitably secured inthe wall 3 preferably cut oil' obliquelyattheir, upper ends as shown at 1-1 and having the hlgh parts '12 of the obliquewalls turned-in the direction of the opening 7. This has the.

within the header 4, thus retarding it to some extent-and permitting it/to be heated ,to the desired temperature-by the heater -9.

effect of making turbulent the flow of the air The ducts "10 are extended downwardly and areopenat the lower'endtodirect the heatedair out at that point. The shoes, shownat 13 and 14 are supported in the desired position to receive the air inside; I support them in that positibn by providing 881d header from one end, an air said ducts havin hooks 16 directly on the ducts 10 which engage with loops or other supporting means on the shoes.

Referring to Fig. 3 in which certain parts are similar to the corresponding parts in the form shown in Figs. 1 and 2 and are correspondingly numbered I have shown a shelf 17 upon which the s des, one of which is shown at 18, may be supported in alignment with the jets of air comlng through the ducts 10. In this form, however, the shoe is completely below the end of the duct, which,

owever, is directed toward the opening therein, so that drying takes place from both the inside and the outside.

As it is obvious that many modifications and changes might be made in my device without the exercise of invention, I do not wish to be limited except by the scope of the appended claims.

I claim: l

'1. A shoe drier comprising a cabinet, a

v ,compartment at one side thereof constitute air into eater in said header, a plurality of ducts extending wall separating the header coming an air header, means for blowin g their ends within the hadercut ofi obliquely and their high sides toward the air inlet end of the header, whereby to cause a turbulent flow of the air and permit it tobe' thoroughly heated, and supporting means for the shoes to be dried soS arranged that one of said ducts may be extended into theinteriorof each shoe.

2. A shoe drier comprising a cabinet, a wall adjacent to the top thereof dividing the interior of the cabinet into an upper air header and a drying compartment therebeneath, an air blower communicatin with one end of said header, an air heater in said passing through the shoes to be dried so arran ed that one of said ducts may rior of each shoe.

3. A drier comprising a cabinet, a compart-ment therein constituting an air header,

be extended into-the intemeans for blowing air into said header from 4 one .end, an air heater,

extending throu compartment, said ducts 'havin their ends within the header cut off obli ue y and their high sides toward the air in ct end of the a plurality-of ducts gh the wall of the header header, to cause a turbulent flow of the air and permit it to be 'thorou hl supporting means for the be dried so agrangedjhat one of said ducts maylbe extended into the interior of each art1c e.

heated, and

4. A. shoe drier comprisin a cabinet hay-'- 111 walls enclosing it out! sides, a wall ad acent to thetop thereof dividing the interior of. the cabinet formed by said walls into an upper air header and m enclosed drying compartment 'therebeneath; an air blower communicating with one end of said header, an air heater in'said header, a ,duct saidfwall into the drying o ow article to v compartment, and means on said duct :for

suspending in said enclosed drying compartment a shoe to'be dried,-whereby the duct is adapted to direct heated air into the interior of the shoe fr ornwhich it escapes into the compartment. Z

In testimony whereof I have hereunto aflixed m. -si ature. Y?-
