To aZZ whom t may concern.

Be itknown that I, EnWARo P. COLE, a citizen of the United States, and a resident of Chicago, county of jCook, and State of Illinois, have invented certain new and useful Improvements in Heaters, of which the following is a specication.

My invention has reference more Vparticularly to a heater of the reflector type which is capable of being used to furnish a current of heated air.`

Electrical heating devices comprising .a

heating element mounted in front of a heatv reflector so as to 'concentrate and project the rays of heat from the element havel come intoeXt/ensive use. These devices, however, as heretofore designed, have been capahle of transmitting heat only by reflection and could not be used to aord a currentot heated air, although the latter use is' often desirable, articularly for drying purposes,

the hair. The principal objects of my invention are to provide an electrical heater of the reflector type which may be used to supply a current or draft of heated air; to use my invention in connection -With heat reflectors of the present type; to ap ly same sol that it does not detract from the utility of the device as a heat reflector; and in'general, to rovide an inexpensive and convenient eater of the reflector type which is easily and quickly adaptable to circulation of heated air.

On the drawin s: Fig. 1 is a si e view of a heater constructed in accordance with 'my invention 'and having parts thereof insection, together with an electric fan placed in position to provide circulation of theheated air. Fig. 2, a similar view partly in section, showing a modified form of heater which is designed to be-used as an attachment for the ordinary electric fan, and

Fig. 3a side View partly in section, of another modification of my-heater.

Referring tothe drawin s, Fig. 1 shows my invention in the form m which heaters of this character are usually constructed and comprises a base 1 with an extension 2 pivoted thereto and adapted to be clamped irl-various positions of pivotal adjustment by a thumb screw or nut 3. At the upper end of the extension 2 is secured a parabolic reflector 4, which hasia heatin element 5 mounted in the base thereof so at the heat i llector directly in front of an electric permit or afford rays emanating :from the element are redirected by the reflector 4 out through the open end of the reflector.

The reflector thus described is substan-4 of the .inner surface of the reflector. This door may be mounted in any manner Which permits convenient opening and closing as for example, by the hinge 6, and there is also a knob 7 for manipulating the door and a latch 8 for holding same in the closed position.

This heater isv constructed so that the re- 4 is at a suitable height to be placed fan 9 of a standard type, videa draft or 'circulation of heated air the tan 1s placed in front of the reliector l substantially as shown in Fig. 1, and the door 25 is opened. Upon supplying current to the heating element 5 and operating the fan, the blast of air from the latter is directed into the reflector 4 into close contact with the heating element, and discharged through the openinoafforded by opening of the door 25, thus a Ording a blast of heated air from and when it is desired to pro 'Q the rear lo enings of the reector which may be utilize for drying the hair or for any other pnrpose.

lThe -construction shown in Fig. 2 is adapted to be used as an attachment for an elect-ric fan and comprises the shell 10 with the heating element 11 at the outer end and a cylindrical portion 12 at the other end of Suitable size to telescope onto the fan guard 13 of the tan 14, and this/shell 10 has an o ening 15 at'the outer end which may be c osed by a door 16, if desired.

This type ot heater has the su porting hase omitted so that it can he used) 1n connection With an oscillating fan and as it is not articularly ada ted to'be used apart from t e tan to provi e reected heat, the door 16 may be omitted or a plain dat plate used tor the door, as the latter is not required to serve as a reflectores in the construction shown in Fig. 1.

The; redector 17 shown in Fig. 3, is de signed particularly\ through the reflector by natural draft caused by the heating element, and this end is hinged on the base 22 so that it normally occupies an upwardly directed position with the opening 23 at tlaebottom through which air is drawn and circulated around the heat ing element 19. The hinged mounting of the reflector however, permits adjustment thereof to horizontal and other positions, so that it may be used as an ordinary heat reflector or in connection with a fan to provide a draft of heated air. nthe opening 23 is, therefore, preferably provided With a door ltl of curved form to complete the reflector surface when closed, and the open end of the reflector may also be provided with the cylindrical shell so that the device is capable of being mounted on a fan guard in the manner shown in Fig. 2.

While have shown and described my invention in a preferred form, l am aware that various changes and modifications may be, made Without departing from the principles of my invention, the scope of which is to be determined by the appended claims.

I claim as my invention:

L lin a device ot the class described, the combination of a concave heat reflector hay# ing an opening in the bottom, a ring-shaped to afford circulation' heating element Within the reflector and ex tending around the edge of the opening so as to afford a clear passage through the opening and heating element, and a door for closing said opening.

2. The combination of a concave reflector comprising an annular shell, the Wall ot Which is convergently curved to 'form a. large opening at one end to a smaller opening at the other end, a heating element positioned within the reflector so that the heat rays therefrom are redirected by the reflector out through the large opening thereof, aud a fan at the large opening of the shell and adapted to supply air into the reflector and discharge same hrough the smaller opening of the reflector.

8. ln a. device of' the class described., the combination of a concave reflector having a heating element mounted therein so that the ra-ys of heat emanating Jfrom said element are concentrated and projected in the direction of the focal axis ot the reflector, a fan adjacent the mouth of the reflector operable to propel a current of air in a direction opposite to that of the reflected heal` rays, and a restricted opening in the bottom of the reflector through which the current of air from the fan is discharged.,
