Claim:
A grill assembly for cooking human food comprising: a housing, said housing comprising a support frame; a plurality of tubular cooking members rotatably mounted with said support frame; a drive assembly for driving the tubular cooking members to rotate relative to the frame, comprising; an electric motor having a drive shaft; a drive chain; a drive sprocket drivingly connected with the motor shaft, the drive sprocket having teeth and being positioned for engaging the drive chain so that rotation of the drive sprocket in engagement with the drive chain pulls the drive chain; the tubular members having sprockets with teeth for engaging the drive chain so that movement of the drive chain in engagement with the sprocket teeth of the tubular members rotates the tubular members relative to the support frame; a drive chain tensioned assembly having a first idler sprocket and a second idler sprocket mounted to a cam assembly; the support frame having a structural reinforcement member, and the idler sprocket being rotatably mounted to the reinforcement member; and wherein the structural reinforcement member has a first and a second rear extension, with an opening between the rear extensions, so that the drive chain can extend from engagement with a tubular member sprocker and pass through the opening about the idler sprocker, and then extend through the opening to be engaged with the drive sprocket.
