  • Patent number: 4483459
    Abstract: A dispensing machine particularly for dispensing bottles or cans. The machine has a storage area formed by a plurality of parallel vertically spaced inclined shelves and at the lower end of each shelf is a pick-up station. A carrier mounted on a carriage moves vertically past the pick-up stations and can receive a bottle from any selected one by operating a release mechanism when it is adjacent the required pick-up station. The carriage takes the selected bottle to a dispensing station at the top of the machine where the carriage tips and rolls the bottle into a fixed position from which it can be removed by a customer.
