Abstract
Abstract An article dispensing mechanism for a vending machine includes at least one serpentine track comprised of a pair of facing cusp-shaped vertical panels. These panels are supported on a pair of facing side plates. Each panel has a plurality of projections which extend horizontally from opposite side surfaces of the panel and extend into rectangular-shaped holes formed in both side plates. Each vertical panel is securely fixed on both plates by twisting the outer terminal portion of the projections which extend outwardly from the rectangular-shaped holes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
127 words
In an article dispensing mechanism for a vending machine including a pair of side plates facing one another at a predetermined spacing and at least one pair of serial cusp-shaped vertical panels disposed transversely between said side plates, said panels facing each other to define a serpentine track, the improvement comprising said vertical panels having a plurality of projections horizontally extending from each side surface, each side plate having a plurality of elongate holes located so that an outer portion of said projections penetrates and extends through said holes, said projections having an outer edge, and said outer portions of said projections are twisted to place said outer edge of said projections in contact with said side plates and fix said vertical panels to said side plates.
Claim 2
Dependent Claim
