Abstract: An article dispensing mechanism for a vending machine is disclosed which includes a pair of side plates which face one another at a predetermined spacing. One pair of serially cusp-shaped vertical panels are disposed transversely between the side plates to define a serpentine track. An upper, open end of the serpentine track is connected to an article loading space and a lower, open end of the serpentine track is connected to an article dispensing space. A spacer member extends vertically and is movable horizontally within a space defined between either one of the side plates and the serpentine track. At least one bracket is connected with the other side plate and, adjacent fixing plates on the spacer member. At least one of the spacer fixing plates or brackets are provided with projections, e.g. screws that can be tightened. At least the other one of the spacer fixing plates or brackets are provided with apertures.
