Abstract
A rotating barbecue grill for uniformly and automatically cooking frankfurters, sausages, hamburgers, steaks, and other food items through the use of rotating rods or rollers defining a grilling surface. One of the rods is directly driven by a motor with the remaining rods rotating in unison by a crank-type drive mechanism. A hot plate is positioned adjacent one of the end rollers so that flat items of food, such as hamburgers, which cannot be turned between the rollers, are moved by the rollers to the hot plate and deposited thereon so as to keep them warm without overcooking.
Claims11
A rotating barbecue grill for use with a motor, comprising:
- (A) a peripheral framework including two oppositely positioned apertured side members parallel to each other with their respective apertures aligned with each other;
- (B) an elongated substantially cylindrical member rotatably mounted through aligned apertures in said side members, having a first end protruding outwardly from the first side member, said first end shaped for removable continuous rotational driving engagement by said motor, and having its other end protruding from said second side member, with either end having a crank-like portion;
- (C) a plurality of elongated substantially cylindrical members passing through respective aligned apertures in the side members, each having a crank-like portion at the end thereof, corresponding to the end of the driven cylindrical member having the crank-like portion, these members in combination with the driven cylindrical member defining a grilling surface for the placement of cylindrically shaped food items between adjacent cylindrical members and for the placement of flat sided food items on top of at least two adjacent cylindrical members;
- (D) a drive member incorporating another plurality of apertures for rotatably receiving the crank-like portions of the driven cylindrical member and the other cylindrical members so that continuous rotational movement of the crank-like portion of the driven cylindrical member imparts similar continuous rotational movement in the crank-like portions of the remaining elongated members;
- and
- (E) a hot plate positioned parallel to one of the elongated members having only one adjacent elongated member so that flat sided food items placed on the elongated members move across the grilling surface and are deposited on the hot plate;
- whereby rotation of the driven cylindrical member causes all of the interconnected remaining elongated members to turn in the same direction and with the same speed as the driven member so as to form a grilling surface with rotating members;
- and whereby cylindrically shaped food items such as frankfurters are automatically turned by the cylindrical members while flat sided food items such as hamburgers are moved across the grilling surface onto the hot plate.

A rotating barbecue grill for use with an electric motor, comprising:
- (A) a plurality of parallel spaced apart cylindrical members, at least every other cylindrical member having a crank-like termination at one end thereof, said cylindrical members combining to define a grilling surface for the placement of food items thereon, and at least one of said cylindrical members with a crank-like termination including means for engaging with said electric motor so as to be continuously rotationally driven by the electric motor;
- (B) means, for maintaining the cylindrical members in the spaced apart parallel relationship to each other while allowing the cylindrical members to turn about their longitudinal axis;
- (C) a drive member rotatably interconnected with each of the crank-like terminations of the cylindrical members so as to impart continuous rotational movement from the cylindrical member driven by the motor to the other cylindrical members and thereby cause these cylindrical members to turn in the same direction at a uniform speed;
- and
- (D) a hot plate mounted to the means for maintaining the parallel spaced relationship of the cylindrical members and positioned adjacent to one of the cylindrical members defining the grilling surface whose upper direction of rotation is toward the hot plate so that flat food items placed upon the grilling surface move across the surface at a uniform rate and are deposited on the hot plate.

A barbecue device for cooking foods comprising:
- (A) means for containing a source of heat;
- (B) an electric motor;
- (C) a plurality of spaced apart rods or rollers, at least every other rod having a crank-like termination at one end thereof, said rods combining to form a grilling surface for the placement of food items thereon so that cylindrically-shaped food items, such as sausages, rest atop adjacent rods and flat sided food items, such as hamburgers, are supported across at least two adjacent rods, and at least one of said rods with a crank-like termination including means for engaging with the electric motor so as to be continuously rotationally driven by the electric motor;
- (D) means, for maintaining the rods in the spaced apart parallel relationship to each other while allowing the rods to turn about their longitudinal axis;
- (E) means, for maintaining the electric motor in engagement with the rod to be driven by the electric motor;
- (F) a drive member rotatably interconnected with each of the crank-like terminations of the rods so as to impart continuous rotational movement from the rod driven by the motor to the remaining rods having crank-like terminations and thereby cause all the rods with crank-like terminations to turn in the same direction at a uniform speed, with the rods not having crank-like terminations free to rotate about their longitudinal axis;
- and
- (G) a hot plate mounted to the means for maintaining the parallel spaced relationship of the rods and positioned adjacent to one of the end rods defining the grilling surface whose upper direction of rotation is toward the hot plate, so that flat food items placed on the grilling surface move across the surface and are deposited on the hot plate;
- whereby the cylindrically shaped food items, such as sausages, are automatically turned by the rods driven by the rod engaged with the electric motor while flat-sided foods, such as hamburgers, are moved across the grilling surface by these rods.
