  • Patent number: 4412607
    Abstract: A vending machine including a plurality of receptacles in which articles to be vended are stored and releasing mechanisms that selectively release the articles from the receptacles. An enabler counts money or other tender deposition in the machine and enables the releasing mechanisms associated with those receptacles containing appropriately priced articles as successive predetermined totals are reached. The money is temporarily deposited in an escrow chamber from which it is released into a bank only after a sensing device determines that an article has in fact been released.
