A grill assembly for cooking human food comprising:(a) a housing, said housing comprising a support frame;(b) a plurality of tubular cooking members rotatably mounted with said support frame, with each of the tubular members having an axis;(c) an electric motor having a drive shaft;(d) a drive chain;(e) 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;(f) an idler sprocket rotatably mounted to the support frame, said idler sprocket having an axis and having teeth for engaging the drive chain so that movement of the drive chain in engagement with the idler sprocket teeth rotates the idler sprocket, the axis of the idler sprocket being aligned with each of the axes of the tubular members; and(g) 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. 44. The grill assembly of claim 43 wherein the sprockets of the tubular members have approximately the same diameter, and the diameter of the idler sprocket is appro ximately the same as the diameter of the tubular sprockets. 45. The grill assembly of claim 44 wherein the teeth of each of the tubular members have a circumference and the teeth of the idler sprocket have a circumference with the upper portion of the idler sprocket circumference being aligned with the upper part of the circumferences of the tubular members. 46. The grill assembly of claim 43 wherein the teeth of each of the tubular members have a circumference and the teeth of the idler sprocket have a circumference with the upper portion of the idler sprocket circumference being aligned with the upper part of the circumferences of the tubular members. 47. A grill assembly for cooking human food comprising:(a) a housing, said housing comprising a support frame;(b) a plurality of tubular cooking members rotatably mounted with said support frame with each of the tubular members having an axis;(c) a drive chain;(d) a drive sprocket rotatably mounted to the frame, the drive sprocket having teeth for engaging the drive chain so that rotation of the drive sprocket in engagement with the drive chain pulls the drive;(e) an idler sprocket rotatably mounted to the support frame, said idler sprocket having an axis and having teeth for engaging the drive chain so that movement of the drive chain in engagement with the idler sprocket rotates the idler sprocket, the axis of the idler sprocket being aligned with each of the axes of the tubular members;(f) the tubular members each having a sprocket with teeth for engaging the drive chain so that movement of the drive chain in engagement with the tubular members sprockets rotates the tubular members relative to the support frame; and(g) an electric motor, the motor having a drive shaft drivingly connected to the drive sprocket so that the motor can rotate the drive shaft and the drive sprocket with the drive sprocket pulling the chain to move in a direction from the tubular members thence toward and about the idler sprocket and thence toward the drive sprocket. 48. A grill assembly for cooking human food comprising:(a) a housing, said housing comprising a support frame;(b) a plurality of tubular cooking members rotatably mounted with said support frame;(c) an electric motor having a drive shaft;(d) a drive chain;(e) 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;(f) an idler sprocket rotatably mounted to the support frame, said idler sprocket having teeth for engaging the drive chain so that movement of the drive chain in engagement with the idler sprocket teeth rotates the idler sprocket, the idler sprocket having a circumference with an upper portion; and(g) 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, each of the sprockets having a circumference with an upper portion with the upper portion of the idler sprocket being aligned with the upper portions of the sprockets of the tubular members. 49. The grill assembly of claim 48 wherein the circumference of the idler sprocket is approximately equal to the circumferences of the sprockets of the tubular members.
