GARMENT DRIER Application filed January 17, 1929. Serial No. 333,175.

This invention relates to certain new and useful improvements in garment driers and has for its primary object to provide garment drying apparatus in the form of a casing or a 5 housing in which sill; and other garments are suspended upon a rotatable hub with heating means and air draft devices associated with the casing or housing to facilitate drying the garments.

A further object of the invention is to proide a garment drier comprising a housing inclosing a rotatable garment supporting frame and wit-h a heating element adjacent the top of the housing and a fan blower communicating with the bottom of the housing for drawing heated air from the upper end of the house and delivering the same into the housing at the lower end thereof andfor rotating the garment drier supporting frame.

A further object of the invention is to provide a garment drier of the above type having a perforated false bottom with the air supply means located beneath the false bottom resulting in a wide spread and diffusion of air blown upwardly through the housing over the garments suspended therein, the top wall of the housing having a screened inlet for the admission of fresh air and an outlet for the exhaust of parts of the heated air.

iVith the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings?- Figure 1 is a side elevational view of a garment drier constructed in accordance with the p resent invention;

Figure 2 is a horizontal sectional view taken on line 2 2 of Figure 1, showing the rotatable spider frame for supporting garments to be dried and the perforated formed bottom in the housing;

Figure 3 is a vertical lonigtudinal sectional view of the garment drier showing the steam heated coil located in the dome-shaped cover of the drier housing, the rotatable frame,

fan blades carried thereby and the air motor or fan for operating the same; g 1

Figure 4 is a horizontal sectional view, similar to Figure 2 with the perforated false bottom broken away to illustrate the angle iron floor structure support therefor;

Figure 5 is a detail sectional view showing the end thrust ball-bearing mounting, for the upper end of the rotatable shaft of the garment drying frame;

Figure 6 is a detail sectional viewshowing the end thrust ball-bearing for the lower end of the rotatable shaft, the fan wheels seatingthe shaft and the perforated false bottom through which the shaft rotatably extends; and H I Figure 7 is a detail sectional view showing the end bracket mounting of the angle iron lower structure.

The garment drier comprises a circular housing 1 of suitable dimensions and proportions, preferably of the size approximately seven feet in height and six feet in diameter, the housing 1 having an inset bottom wall 2 and an upwardly arched dome-shaped cover 3 provided with a central outlet 4: for heated and spent air. A glass closure door 5 is hingedly mounted as at 6 in the side wall of the housingl to permit entry of a person into the housing for adjusting garments upon drying racks and for other purposes. A screened air inlet 7 is provided in the cover 3 as shown in Figure 1 for the admission of fresh air to be circulated through the housing,

A garment drying rack is rotatably mounted in the housing 1 and comprises a vertical shaft 8 having a ball thrust bearing 9 at its lower end upon the central portion 11 of the spider frame 12 that is located below the bottom wall 2 as shown in Figures 3 and 6, while the upperend of the shaft 8 has a ball thrust bearing 13 with the central portion 14 of the upper spider frame 15 extending horizontally across the housing 1 as shown in Figure 3. Radial arms 16 are carried by the upper end of the shaft 8 and have concentric garment supporting rings 17 fixed thereto in spaced relation as shown in Figure 2.

A heating device is associated With the housing 1 and comprises a coiled pipe 18 located in the upper end of the housing 1 above the spider frame 15 as shown in Figure 3, the coiled pipe 18 having an inlet pipe connection 19, valve controlled as at 20 and an outlet pipe connection 21, valve controlled as at 22. Steam is admitted through the pipe 19 and flowing through the coil 18 heats the upper end of the housing 1 and exits from the coil through the pipe 21.

An electric motor 23 and fan blower 24 are mounted upon the bracket 25 carried by the lower end of the housing 1 exteriorly thereof and said fan blower 24: has an outlet pipe 26 tan entially entering the housing 1 at a int a ove the bottom wall 2. A fan whee 27 is fixed as at 28 to the lower end of the shaft 8 ad'acent the bottom wall 2, the blade 27 exten ing to points adjacent the side walls of the housing 1, the fan blower rotating the fan blades 27 for rotating the shaft 8 and drier frame comprising the arms 16 and rings 17. A pipe 29 communicating at 30 with the upper end of the housing 1, and more particularly the cover 3 leads to the fan blower 24 for drivin the heated air from the upper end of the housing and delivering the same into the housing at the lower end thereof. The motor 23 is connected with a suitable source of electric energy and the s ed thereof is controlled by the rheostat 3fthe amount of air drawn through the pipe 29 being controlled by the damper 32.

A false bottom is disposed above the bottom wall 2 and comprises a plurality of parallel horizontal angle irons 33 having opposite ends thereof bent to form brackets 34 secured as at 35 to the side walls of the housin 1, the angle iron bars 33 supporting a perforated false bottom plate 36 above the fan 27. Heated air blown into the lower end of the housin is driven by the fan 27 upwardly throug the perforated false bottom 36 for even distribution through the housing and onto and over the garments suspended and rotated therein.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, it being noted that air entering the uper end of the housing through the screened inlet 7 is heated upon coming into contact with the steam coil pipe 18 and the heated air is withdrawn from the upper end of the housing by the fan blower 24 through the pipe 29 to be delivered into the lower end of the housing for upward diffusion through the perforated false bottom plate 36 to contact the arments suspended in the housing. The fan blower 24 operates the fan wheel 27 for rotating the shaft 8 and garment drying frame and the speed of rotation of said frame may be controlled by the rheostat 31 controllin the speed of rotation of the motor 23 an damper 32 in the pipe 29. Excess air exhausts through the outlet 1 in the cover 3, While a constant supply of fresh air enters through the screened inlet 7 due to draft or suction created in the housing.

IVhile there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

I claim 1. In a garment drier, a housing, a rotatable garment drying frame in the housing, a heater at the upper end of t is housing, means for withdrawing heated air from the upper end of the housing and delivering the same to the lower end of the housing for upward movement therein, and a fan wheel impeller on the rotatable drier operated by the current of air entering the lower end of the housing.
