ABSTRACT:
A cart conveyor and dispensing device (10) is a preferred embodiment of the invention and is described herein. The conveyor (10) includes means for propelling a cart (26) through the conveyor (10). The propelling means includes a continuous member that carries a member for releasably engaging the rotating portion of a cart wheel. In a preferred embodiment, a chain assembly (29) carries crosspieces (46) that engage the center wheel (52) of the cart (26). If the cart is precluded from progressing through the conveyor (10), the chain assembly (29) continues to move with the crosspieces (46) rolling past the center wheel (52) without damaging the cart (26). A plurality of conveyor sections can be interconnected to create, for example, a three-conveyor system (91) that may accommodate more carts (26) and presents a return end (12) at a locus more conducive to return of carts (26) for the appropriate rewards.
