Abstract

Abstract A food broiler in the form of a home appliance and a commercial appliance employs a food gril-holder suspendable on a retaining means in a broiling chamber formed by three cooking elements for broiling food. The broiler includes a food broiling channel or chamber formed by the broiling elements, a food grill-holder and a means for suspending the grill-holder in the broiling chamber. Broiling or cooking is controlled by temperature or time of exposure or both. Switch means is provided for electrically coupling the heating elements selectively for varying the heat intensity in the cooking chamber, as desired.

Claim 6
Dependent Claim 40 words
A food broiler as in claim 4 and further providing means for controlling the speed of said drive means for controlling the speed of rotation of said capstan for controlling the time said grill-holder is in said circular broiling chamber.
Claim 7
Dependent Claim 192 words
A food broiler having a broiling chamber adapted to broil food on both sides at the same time, said broiler including; first and second heating elements spaced to Provide a vertical chamber between them, a third heating element spaced above and substantially between said first and second heating elements, said first and second and third heating elements forming a three sided broiling chamber, means coupled to each of said heating elements for selectively coupling each of said elements to an energy supply for providing energy to heat said elements as desired, means for controlling the energy provided to said heating elements for controlling the temperature within said broiling chamber, rod means extending horizontally along said broiling chamber for supporting a food retainer within said broiling chamber, food retainer means adapted to be supported by said rod means for suspending food in said broiling chamber, said food retainer means including a first part and a second part hinged at one end and openable about the axis of said hinge and; a pair of cooperating members adapted to receive said food retainer for holding said first part and said second part in closed position.
Claim 8
Dependent Claim 192 words
A food broiler having a broiling chamber adapted to broil food on both sides at the same time, said broiler including; first and second heating elements spaced to Provide a vertical chamber between them, a third heating element spaced above and substantially between said first and second heating elements, said first and second and third heating elements forming a three sided broiling chamber, means coupled to each of said heating elements for selectively coupling each of said elements to an energy supply for providing energy to heat said elements as desired, means for controlling the energy provided to said heating elements for controlling the temperature within said broiling chamber, rod means extending horizontally along said broiling chamber for supporting a food retainer within said broiling chamber, food retainer means adapted to be supported by said rod means for suspending food in said broiling chamber, said food retainer means including a first part and a second part hinged at one end and openable about the axis of said hinge and; a pair of cooperating members adapted to receive said food retainer for holding said first part and said second part in closed position.
