, OF DETROIT, MICHIGAN, A CORPO- ELECTRIC COOKER.

Specification of Letters Patent.

Patented July 1 7, 1 906.

To all whom, it may concern:

Be it known that I, GEORGE J. SCHNEIDER, a citizen of the United States,.residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Electric Cookers, of which the following is a specification, reference being had therein to the accompanying drawin s.

The invention relates to electric cookers, and is more particularly designed for use in broilers. Y

The invention consists in certain novel features of con'struction,'as will be more fully hereinafter set forth.

- In the drawings, Figure 1 is a cross-section through the cooker. Fig. 2 is a perspective view of one of the removable heaters detached. perspective viewof the complete heater.

As shown, A and B are two end plates, preferably formed of cast metal and preferably having lugs or standards C formed integral therewith. The front frame A is provided with an opening D, which may be closed by hinged doors E, the latter being slightly cut away at the center to form an inspection-opening F.

G is a sheet-metal casing connecting the framesA. and B. and preferably secured to inwardly extending'marginal flanges thereon.

The electric heaters are arranged within the casing C and preferably at each side thereof upon opposite sides of the o eningD in the frame A. These heaters are ormed of suitable hi h-resistance electric conductors capable of eveloping the required heat when an electric current is passed thepethrough.

To prevent danger of direct contact between the heating-conductors .and the food placed within the casing, I have devised a grate ofthe following construction: H is a gratin or 0 on frame extending parallel to the si e of t 1e heater between the front and rear frames A and B. This grating forms a mounting for the'heating-conductor I, which is preferably in the form of coils of wire.- These coils are arranged on the rear side of the grating that is, on the side adjacent to the side of the casing-and the coils are so arranged as to expose the greater part thereof in line with t e openings in the -grat1ng.

ing H.

The grating itself is preferably formed of metal, and to insulate it from the heatin coils it is preferably enameled with a suitab e insulating material.

In the specific construction illustrated in Fig. 2 the grating H is formed of a substantially rectangular outer frame a, a longitudinally-extendlng central bar 6, and a series of vertical bars 0, extending between the top and bottom bar and the centralbar, these vertical bars beingstag ered on opposite sides of the central bar. If the insulation is suflicientlv perfect, the heating-coils may be strung directly upon the grating H, and the latter may be provided with integral pins or lugs d, around which the wire at o posite ends of the coils is passed. If desire further security in insulation may be provided by arranging insulating-spools upon these pins in addition to the enameled facing. It is desirable to have a construction in which the grating may be easily cleansed when necessary, and to this end I have mounted the grating H so as to be easily removable from the casing.

screws engaging the lugs M on the grating to the lugs J on the front and rear frames. The electric connections for the heating-conductors are automatically established upon the positioning of the grating by providing insuated contact-pieces N, mounted on the frame, and cooperating contact-pieces Oon the grat- These are so arranged that when the grating is in the position indicated in Fig. 1 the members N and O are in contact. From the contact-pieces N the current is conveyed through insulated conductors P, leading to suitable binding-posts Q on the outside of the casing. 1

I/Vith the construction described the radiation from the heating-coils I will pass through the spaces between the grate-bars-c and will be protected against the food which is entered throu h same I time lilie heating-conductors are effec- ICU the door-opening D. At the tually guarded from contact with the food or with the holder therefor by the grating H.

What I claim as my invention is 1. In an electric cooker, the combination with a heating-conductor, of a protecting-' back and. forth opposite the spaces between said bars. I

3. In an electric heater, the'combination with a grating of a heating-conductor mount-' ed upon one side of said grating, exposed to radiate its heat through the opening in said grating.

4. In an electric cooker, a grating having parallel bars and a heating-conductor mounted u on said bars arranged to extend back .and orth thereon opposite the openings between said bars.

5. In an electric cooker, a grating provided with parallel bars and a heatin -conductor comprising coils extending back and forth across said grating between said bars and mounted upon the grating.

6. In an .electric cooker, the combination with a casing, of a grating removably secured within said casing, and -a heatingconductor mounted upon said removable grating.

7. In an electric cooker, the combination with a casing, of a grating removably secured within said-c casin a heating conductor mounted upon sai grating and removable therewith and cooperating contacts upon I said casing and grating, through which current is conveyed to the heating-conductor.

8. In an-electric cooker, the combination with a casing, of a grating secured within and parallel to one side of said casing, and a heatin -conductor arranged in the space between said grating and the side of the casing and exposed to radiate its'heat through the opening in the grate. 1

- 9. In an electric cooker, the combination with acasing having an opening at one end thereof, of a grating within said casing parallel to the side thereof and adjacent to said opening, and a heating-conductor arranged in the space between said grating and the side of the casing and exposed to radiate its heat through the openings in the grating.

10. In an electric cooker, the combination with a casing having parallel 'side walls, an opening in one end thereof, of a pair of gratings arranged upon opposite sides of said opening within said casing, and heat-conductors arranged in the space between said gratings and the adjacent sides of the casing and exposed to radiate heat through the openings in the grating.

In testimony whereof I afiix my signature in presence of two witnesses. GEORGE J. SCHNEIDER.
