ELECTR IC HEATER Filed July 28, 1950 Patented Jan. 12, 1932 UNITED STATES AIL-BERT SEALE, OF MIDDLESBORO, KENTUCKY ELECTRIC HEATER Application filed July 28,

This invention has as an object to utilize the stand of an oscillating fan as supporting means for a heater, thereby assuring a distribution of the heat and the provision of an article susceptible of use either as a fan or heater, the stand being common to both adaptations.

In accordance with the invention, the fan and the heater elements are interchangeable and attached directly to the oscillating portion to move therewith in order to distribute the air currents of the one and the heat rays of the other.

WVhile the drawings illustrate a preferred embodiment ofthe invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design m y be varied and changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spiritthereof.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which:

Figure 1 is a perspective view illustrative of an embodiment of the invention.

Figure 2 is a side view thereof, partly in section, and arts broken away.

Correspon ing and like parts are referred to in the following description and designat ed in the several views of the drawings by like reference characters.

In both views of the drawings, the motor and stand illustrated are of Well known construction and are parts of a conventional form of'electric fan of the oscillating type.

As shown in the accompanying drawings,

7 the fan and guard are replaced by an elec tric heater which comprises a reflector 1,

guard 2, arms 3, and heating element including a core 4 of refractory material and a resistance 5 supported thereon.

An opening 6 is formed centrally of the reflector 1 and the base of the core 4: extends thereover. A hollow projection 7 extends rearwardly from the reflector 1 and is attached thereto in line with the opening 6. An electric cord 8 passes through an open- 5 ing formed in a side of the hollow projec- 1930. Serial 110. 471,172.

tion 7 and is connected to the terminals of the resistance 5. The cord 8 terminates in a plug 9 which is adapted'to engage a twoway plug 10 included in an electric cord 11 of the usual fan motor. A lug 11 projects from the rear side of the reflector 1 and the cord 8 is connected thereto. A finger piece 12 is provided upon the upper rear side of the reflector 1 for convenience of handling the heater when placing it in position or removing it from the stand. The arms 3 are of a length to properly support the heater and are attached to the housing of the motor in substantially the same manneras the arms of the fan guard when the latter is in place. The rear end of the hollow projection 7 has an opening formed therein for the passage of the shaft13 of the motor. When the heating attachment is removed, the fan (not shown) is mounted upon the shaft 13 in the usual manner.

The stand comprises a pedestal 14 and a head 15 pivoted thereto. The fan motor is enclosed in a housing 16 which is pivoted to the head 15 to oscillate about a vertical axis.

A link 17 is pivoted at one end to the head 15 and its other end has a wrist pin connection 18 to a vertical shaft 19 which is connected to the motor in any determinate manner to insure an oscillation of the housing 16 when the motor is running. These parts are of well known construction in an electric fan of the oscillating type." The electric cord 11 supplies current to the motor from a suitable sourceand thetwo-way plug 10 is included in the length thereof to admit of connecting the heating element in circuit with the motor.

In accordance with the invention, the usual fan is removed from the shaft 13 and the guard therefor detached from the motor housing 16. These parts are replaced by the heater attachment, the arms 3 of which are connected to the motor housing 16 by the same means provided. for securing the fan guard when placed in position for service. The heater element is connected in the motor circuit by haying the cord 8 connected to the plug 10 in {the length of the cord 11. When the ci'rcuitlis completed, the current flows through the resistance Sand motor, and the 109 i heater is oscillated in substantially the same manner as the fan, thereby throwing the heat rays at different angles to insure a better distribution of the heat. The end of the shaft 13 is protected by entering the hollow projection 7 and when the arms 3 are detached from the motor housing 16 the usual fan and fan guard (not shown) may be readily placed in position and the device utilized as an electric fan in the manner intended, as will be readily appreciated.

What is claimed is:

An electric heater comprising a stand, a motor housing mounted on the stand and adapted to oscillate, and a heater connected with the motor housing to oscillate therewith, said heater including a reflector in which is formed a central opening, a core of refractory material having a base covering the opening in the rear of the reflector and secured to the latter, a resistance mounted upon the core, a hollow projection extending rearwardly from the reflector in line with the opening thereof and having an opening in its outer end to receive the end of the motor shaft, and an electric cord passing through the hollow projection and connected to the terminals of the resistance.

In testimony whereof I afiix my signature.
