Abstract
Dispensing shelves for cabinet-type vending machines having a plurality of different sized helical feeder coils all on the same level for advancing articles interposed between the convolutions of the coils to a delivery opening. The width of the troughs holding the coils is variable on the same shelf level and the placement of the helical feeder coil within a trough is variable. The shelf is of either a sheet metal or a molded, high-density plastic type material. Drive units for the helical coils are removably mounted for operation without fastening devices and are adjustably laterally mounted within a single trough. A unique shelf support rail unit maintains the shelf side panels of the vending machine against lateral movement and bending. Further, a unique door closure member maintains the shelves in their vending positions at all times when the door is closed.
