A machine particularly adapted for dispensing light items packaged in pliable pouches or packets having a machine graspable crowned carrier. The items are propelled in a queue through a tubular cartridge along a track having a ratcheting mechanism to be individually dispensed. A motorized reciprocation bolt engages the mechanism at the back of the cartridge. Multiple cartridges can be grouped together in an expandable array using an interlocking bar and T system to form a removable magazine. Each cartridge can be selectively addressed and activated by its dedicated motorized bolt. In a preferred embodiment of the ratcheting mechanism, the heads of the package carriers are held within a C-shaped track and propelled by the alternating back-and forth motion of a crenelated drive rack successively pushing a sled at the rear of the package queue. A self-engaging brake impedes backward movements of the sled and packages during a return stroke of the drive rack. A coupler is provided for conveniently transferring a batch of products temporarily mounted on a storage and transportation rail directly onto the ratcheting mechanism from the back of a vending machine.
