CORPORATION OF ILLINOIS.

ELECTRICALLY-OPERATED LAVATORY DRIER.

Original application filed November 29, 1927, Serial No. 236,490. Divided May 7, 1928. Serial No. 275,718.

This application is a division of application, Serial No. 236,490, filed Nov. 29, 1927.

This invention relates to that type of lavatory driers in which a blast of heated air is discharged as a drying means by an electrically operated air mover or blower, and the present improvement has for its object:

To provide a structural formation and combination of parts involving the enclosing shell or casing, the air blower and the operating motor and controlling switch, whereby the supply of air to the air blower is taken from a point remote from motor and from the controlling switch, in order to avoid contamination of such air with the odor and other offensive properties of the oils used as a lubricant on such mechanisms, all as will hereinafter more fully appear.

In the accompanying drawing:

Fig. 1, is a transverse section on line 1,-l, Fig. 2, of an apparatus embodying the preferred form of this invention.

Fig. 2, is a longitudinal section on

line

2,2, Fig. 1.

Like reference numerals indicate like parts in both views.

In the preferred form of the invention shown in the drawing, the enclosing housing 1 of the drier is of an open bottom rectangular shell form, provided on its top wall with an outlet nozzle 2, preferably arranged in an oblique manner as shown in F i 1. The open bottom of the housing 1, is adapted to enclose a base plate 3, fixedly secured to said housing with such base plate forming a support for the hereinafter described air mover or blower, electric motor for such air mover and the switch mechanism controlling such motor.

The shell or casing 5 of the air mover or blower above referred to, is arranged centrally within the enclosing housing 1, of the apparatus, with the electric motor 6, ar-

ranged at one side of the casing 5 and the controlling switch 11 for said motor arranged at the opposite side of said casing 5,

K as illustrated in 2.

As in a former application, Serial Number 114,058, filed June 7, 1926, a heating element 7, of the electrical resistance type is and this application filed arranged in the outlet neck of the shell or casing 5 of the air mover or blower, said outlet neck having communication with the heretofore described outlet nozzle 2, of the main housing 1.

a closed supply trunk 9, having communica- 131011 with an opening 5 of the casing 5, the inlet opening 10 of each trunk 9, and preferably at the lower end of the same, extending down through the base plate 3. With such arrangement pure air from beneath the main housing 1, of the apparatus, remote and free from contamination of lubricant odors, etc. of the operating mechanism of the apparatus, is supplied to the air mover or blower and is in turn discharged in a heated condition through the outlet-nozzle 2 for lavatory drying uses.

The controlling switch mechanism 11, shown in the drawing for controlling the supply of electricity to the electric motor 6, and heating element 7, forms the subject matter of a prior application for patent, Serial Number 236,490, filed November 29, 1927, and of which the present application is a division.

I claim as my invention:

In an electrically operated drier of the type described, the combination of a main enclosing housing having an open bottom, a base plate fitting the open bottom of said housing, an air mover having its enclosi casing mounted at the mid-length of base plate and having an outlet extending through a wall of the main housing, a heating element arranged in said air mover casing, a motor for said air mover arranged at one side of its enclosing casing, a switch E 1,7ao,aa7

mechanism controlling said motor and arbase plate and openin at one end through ranged at the other side of the air mover said base plate with Its other end having casing, and a closed inlet trunk arranged communication with the interior of the air 10 between the motor and the air mover casing mover casing.

5 with a wall of said casing having a bearing In testimony whereof I hereunto aflix my orifice for the shaft of said motor, said closed signature. inlet trunk being carried by the-aforesaid v GEORGE A. BURGESS.
