Claim 6

Apparatus for heating and dispensing food articles supported on elongated skewers, said apparatus comprising: conveyor means defining an elongated path of travel between skewer receiving and discharging stations, said conveyor means including a pair of endless conveyors spaced transversely from each other relative to the length dimension of said path; driving means operatively associated with said conveyor means for moving said endless conveyor along said path; heating means disposed adjacent said path; a plurality of skewer support means secured on and spaced longitudinally along each endless conveyor, each skewer support means on one of said conveyors being paired and transversely aligned with a skewer support means on the other of said conveyors, each skewer support means comprising a bracket member having a closed end for loosely carrying a skewer portion while travelling along said path and an open end which is sufficiently wider than the thickness dimension of said skewer portion to freely receive said skewer portion when the skewer portion is dropped into said bracket member at said receiving station and to permit the received skewer portion to drop freely of its own weight from the bracket member at said discharging station; wherein said bracket members are oriented on said conveyors such that said open end is directed generally upward when passing said receiving station and generally downward when passing said discharging station; wherein each of said bracket members includes a pair of edges which mutually diverge from said closed end toward said open end; and means for continuously rotating said skewers in said bracket members as said skewers are carried along said path, said means for continuously rotating comprising; an elongated gear track disposed adjacent said path; at least two spaced roller bearings secured in each bracket member for rotatably supporting the received skewer portion; and means continuously urging the bracket members disposed in said path toward said elongated gear track to positively engage the supported skewers in direct contact with the gear track at a skewer location intermediate the bracket members.

Claim 7

Apparatus for heating and dispensing food articles supported on elongated skewers having an elongated, smooth support portion of substantially constant thickness on which at least one food article is supported, said apparatus comprising: conveyor means defining an elongated path of travel between skewer receiving and discharging stations, said conveyor means comprising a pair of endless conveyors spaced transversely from each other relative to the length dimension of the path; driving means operatively associated with said conveyor means for moving said endless conveyors along said path; heating means disposed adjacent said conveyor means along said path; a plurality of skewer support means spaced longitudinally along each endless conveyor, each skewer support means on one of said conveyors being paired and transversely aligned with a skewer support means on the other of said conveyors, wherein each skewer support means comprises a bracket member having bearing means for rotatably supporting a portion of a skewer while travelling along said path and skewer receiving means extending from said receiving station and permitting the received skewer portion to freely fall onto said bearing means; and means for continuously rotating said skewers in said bearing means as said skewers travel along said path, said means for continuously rotating comprising a rack gear disposed adjacent and in substantially parallel spaced relation with said path, and means continuously urging said bracket members toward said rack gear to positively and directly engage the elongated smooth support portion of each skewer in said path with said rack gear.

Claim 8

Apparatus for heating and dispensing food articles supported on elongated skewers having an elongated, smooth support portion of substantially constant thickness on which at least one food article is supported, said apparatus comprising: conveyor means defining an elongated path of travel between skewer receiving and discharging stations, said conveyor means comprising a pair of endless conveyors spaced transversely from each other relative to the length dimension of the path; driving means operatively associated with said conveyor means for moving said endless conveyors along said path; heating means disposed adjacent said conveyor means along said path; a plurality of skewer support means spaced longitudinally along each endless conveyor, each skewer support means on one of said conveyors being paired and transversely aligned with a skewer support means on the other of said conveyors, wherein each skewer support means comprises a bracket member having bearing means for rotatably supporting a portion of a skewer while travelling along said path and skewer receiving means extending from said receiving station and permitting the received skewer portion to freely fall onto said bearing means; and means for continuously rotating said skewers in said bearing means as said skewers travel along said path, said means for continuously rotating comprising a rack gear disposed adjacent and in substantially parallel spaced relation with said path, and means continuously urging said bracket members toward said rack gear to positively and directly engage the elongated smooth support portion of each skewer in said path with said rack gear.
