ELECTRIC DRIER.

Application filed February 25, 1926. Serial No. 90,479.

This invention relates to new and useful improvements in electric driers, and particularly to driers of that type in which in addition to means for generating hot and cold blasts of air, a source of heat and light in the form of an electric lamp is provided.

It is the object of the present invention to provide a drier of simple construction and one in which both sources of heat may be utilized to the greatest possible advantage.

With this object in view, I provide a light reflector so constructed that it serves for the double purpose of projecting a concentrated beam of heat and light from the lamp and acts also as a fan for propelling air. This is preferably accomplished by providing openings in the reflector through which, by means of blades mounted on or forming parts of the reflector, preheated or cold air maybe drawn past the reflector. The lamp is arranged in the focus of the reflector in the path of the blast of air, whereby the heat generated by the lamp will be more readily delivered at the desired point.

The following is a detailed description of a preferred embodiment of my invention.

' In the drawings, Fig. 1 is a vertical crosssection of the drier forming the subject matter of the present invention; Fig. 2 is a front view of the combination blower and reflector; Fig. 3 is a sectional view taken along lines 33 of Fig. 2; and Fig. 4 is a sectional view taken along lines 44 of The device is enclosed in a casing composedof acast-iron ring or drum 1 and a sheet metal cylinder 2 fastened to the former. The casing ends in a tapering tube 3,

- to the free end of which a directing nozzle 4 may be removably attached by means of spring clips 5. The inlet opening of the casing is covered with a wire net or screen 6 fastened to the drum 1. Two or more turns of resistance wire are mounted on drum 1 by tangentially with respect to the reflector.

The blades 16 and reflector 14 present pockets which are substantially V-shaped in horizontal and vertical cross-section. The upper part of the V (near the edge of the reflector) is closed at 17 and the pockets open at 18 in the direction of rotation of the shaft 10. The openings 15 are within the confines of these pockets. When the reflector 14 is rotated, the blades 16 force air drawn in at the intake through the openings 15 in the reflector towards the outlet of the casing. By means of longitudinal blades 19 provided on the inside of tube 3, the circular motion of the air blown out is caused to take a substantially rectilinear motion. By means of the heating. element 7, the air drawn in by the blower may be heated. It will be apparent that when the element 7 is heated, the air impinging on the rear of reflector 14 is in a preheated condition and that theblades 16 draw on a supply of heated air which has previously received its quota of heat from the rearwardly located heating element 7 prior to the moment when the air reaches the rear face of the rotating reflector. It will be obvious to those skilled in the art that the shape and positioning of the blades 16 may be varied to suit operating requirements.

An incandescent electric light bulb 20 is mounted by means of a bracket 21 on the casing 2. The lamp 20 constitutes a source of radiant energy which is focused with respect to the reflector 14 so as to concentrate its rays at the desired point. Air forced through the openings 15 will sweep past the lamp 20 and carry the heat developed by the lamp towards the outlet. The switching system 11 is so arranged that the speed of the motor 9, the heating of element 7 and the lighting of lamp 20 may be suitably conopenings through which air may pass, a motrolled and correlated in the well-known manner.

What I claim is:

1. In a drier, a reflector provided with openings through which air may pass, a motor for rotating said reflector, an incandescent electric light bulb at the focal point of said reflector and a heating element located behind said reflector rearwardly ofits axial point, whereby the propulsive efleot developed in the openin of the rotating reflector is exercised Wholly air which has previously received its q ta of heat from the rearwardly located heating element prior to v the moment when the air reaches the rear face of the rotating reflector.

2. In a drier, a reflector provided with tor for rotating said reflector, a heating element behind said reflector, and an incandescent electric light bulb at the focal point of said reflector. p

3. In a drier, a casing having inlet and outlet openings, means including a reflector for projecting a stream of air from said inlet through said outlet opening, a motor for rotating said reflector, an electric light arranged in said casing at the focal point of said reflector, and a heating element behind said reflector'and adapted to heat the air to be projected through the casing.

name to this specification, this 23rd day of February 1926.
