  • Patent number: 4327843
    Abstract: A dispensing mechanism for singularly removing a cup from the bottom of a vertically nested stack of cups in a hopper is described. This mechanism, designed principally for beverage vending machines, has a pair of coacting jaws which each contact nearly one-half the periphery of the cup. Each jaw has sufficient flexibility to fully conform to the cup contour thereby grasping cups having varying dimensions. After the cup is grasped, the jaws are moved axially with respect to the cup to withdraw the cup from the stack. The jaws then open to release the cup and return to their initial position to be ready to grasp the next cup. A plurality of resiliently-biased fingers placed about the bottom of the hopper hold the stack of cups; however, when a cup is drawn away, they retract sufficiently to release that cup but grasp the next cup beneath the lip thereof.
