ELECTRIC HEATER AND COOKER.

Application filed February 10, 1928. Serial No. 253,382.

This invention relates to heaters oi" the type in which a reflector is supported on a stand with the optical axis of the reflector normally laterally directed, but in which the reflector may be tilted so that its optical axis is directed upwardly, an electric heating element being supported from and in front of the reflector. My object is to provide a heater or this t pe with supporting means on which, a kettle or the like may be set while the reflector is positioned with its optical axis laterally directed and which, when the reflector is positioned with its optical axis upwardly directed, may be ad justed to provide a large or small supporting area for cooking utensils, whileat the same time the support forms a guard for the heating element.

,flector adjacent its rim a grid, the surface of the grid lying substantially in the plane or the rim of the reflector and hingedly connecting with said grid wing members which when swung outwardly will extend beyond the rim or" the reflector to provide a large horizontal supporting area when the reflector is positioned with its optical axis directed upwardly. I also hingedly con nect with said grid a support which is adapted tooccupy a substantially horizontal position when the reflector has its optical axis directed laterally, one of the other wings being adapted to be engaged therewith to form a rest for the'outerend of the support. I

The heater is constructed substantially as,

hereinafter described and illustrated in the.

accompanying drawings in which Fig. l is a plan view of the heater with the grid in normal or unextended pos1t1on,.

the optical axis of the reflector being vertical; I

Fig. 2 1s a similar view showing the grid extended; 7

7 by the grid.

The stand isprovided with stops 8 and 9, the stop 8 being adapted to limit the move ment of the head in one direction and the stop 9 to limit the movement of the head in the other direction. This avoids the necessity of providing a frictional locking engagement between .the head and stand, and

thus eliminates danger of the head slipping when weight is applied thereon.

Secured to the head is the reflector plate 3, which is of circular concave form, and may by rocking the head on the stand,.be positioned so that its optical axis is either vertically or laterally directed.

At the centre of the reflector is mounted a heating element 4, which may be of any or dinary construction and need not, therefore,

p v be described in detail. I attain my objectby securing tothe re-.-

Secured to the reflector adjacent the rim is an openwork frame or grid 5, which forms a guard for the heater, and also, when the:

eral utensils at the one time, I hingedly mount on the grid 5 the extension members 6 and 7, which, when swung outwardly as shown in Fig. 2, result in a considerable increase in the total supporting area provided In order that the heater may be used for boiling a kettle or the like whenthe reflector has its optical axis laterally directed, I secure to the inner face of the grid a platform extension 10, which when the reflector is in, the position shown in Fig. 4, lies over the heating element. A portion 11 of the grid is hingedly mounted on the main part, and is adapted, as will be seen from the said Fig. 4, to be swung atan angle to the main part of the grid to form a platform, this platform, being provided with projections 12 which engage a cross bar of the extension when said platform is in alinement with the extension. adapt-ed to be swung up and engaged with the platform ll'adjacent its outer end to form a support therefor, and its inner surface, when in said position, maybe used as a toast rack.

The platform 11 and member 7 are each provided with handles 13 of fibre or other The extension member 7 is also receive the platform 11, and the extension members 6 and 7, so that when the latter are in their folded up position, their outer surfaces are flush with the outer surface of the main part of the grid.

From the above description it will be seen that I have devised a grid which may be used to support cooking utensils whether the optical axis of the reflector is directed laterally or vertically, and which may be opened up to provide a supporting surface having a much larger area than when folded.

What I claim is:

1. In an electric heater, the combination of a stand; a concave reflector mounted on the stand; an electric heating element supported in said reflector; a grid secured adjacent the rim of the reflector and having its outer surface substantially parallel to the plane of the rim; and a platform hingedly mounted on said grid above the element whereby it may occupy a position parallel to the grid or extend outwardly at an angle thereto in the path of the heat reflected by said reflector.

2. In an electric heater, the combination of a stand; a concave reflector mounted on the stand; an electric heating element supported in said reflector; a grid secured adjacent the rim of the reflector and having its outer surface substantially parallel to the plane of the rim; a platform hingedly mounted on said grid above the element whereby it may occupy a position parallel to the grid or extend outwardly at an angle thereto in the path of the heat reflected by said reflector; and means for supporting the platform in said extended position.

3. In an electric heater, the combination of a stand; a concave reflector mounted on the stand; an electric heating element sup ported in said reflector; a grid secured adjacent the rim of the reflector and having its outer surface substantially parallel to the plane of the rim; a platform hingedly mounted on said grid whereby it may occupy a position parallel to the grid or extend outwardly at an angle thereto; and a fixed extension of said platform on the inner side of the grid.

4. In an electric heater, the combination of a stand; a concave reflector mounted on the stand; an electric heating element supported in said reflector; a grid secured adjacent the rim of the reflector and having its outer surface substantially parallel to the plane of the rim; a platform hingedly mounted on said grid whereby it may occupy a position parallel to the grid or extend outwardly at an angle thereto; and a supporting member hingedly mounted on said grid whereby it may occupy a position parallel to the grid or engage with the platform adjacent the outer end thereof when the latter is in extended position.

5. In an electric heater, the combination of a stand; a concave reflector mounted on the stand; an electric heating element sup ported in said reflector; a grid secured adjacent the rim of the reflector and having its outer surface substantially parallel to the plane of the rim; a platform hingedly mounted on said grid whereby it may occupy a position parallel to the grid or extend outwardly at an angle thereto; a supporting member hingedly mounted on said gritil whereby it may occupy a position parallel to the grid or enga e with the platform ad jacent the outer end thereof when the latter is in extended position; and a fixed extension of said platform on the inner side of the grid.

6. In an electric heater, the combination of a stand; a concave reflector mounted on the stand; an electric heating element supported in said reflector; a grid secured adjacent the rim of the reflector and having its outer surface substantially parallel to the plane of the rim; a platform hingedly mounted on said grid whereby it may occupy a position parallel to the grid or extend outwardly at an angle thereto; and a fixed extension of said platform on the inner side of the grid, said grid being recessed to re ceive the platform and supporting member whereby when they are in folded position heir outer surfaces are substantially flush with the outer surface of the grid.
