Abstract
Abstract A grill device is disclosed comprising a firebox including sides and a grid extending between the sides. Two side walls extend above the firebox and support a rotatable spit. A grease-drip pan extends upwardly from the back of the firebox between the side walls. Legs are fastened to opposite sides of the firebox. A warming chamber is positioned beneath the firebox and is adapted to receive one or more flat plates having raised peripheral walls and a handle. Auxiliary warming chambers are provided on the rear surface of the grease-drip pan. The firebox can be secured in either a horizontal plane or in a vertical plane by means of cradles carried by the legs. Each of the cradles includes a downwardly-extending opening and two stops which cooperate with a stub-shaft and transverse arm carried by the firebox.
