  • Patent number: 5098339
    Abstract: The coin dispensing device is adapted to be disposed at the bottom of a vertical coin hopper and receives loose coins to be dispensed from the coin hopper. A first rotating agitator disk withdraws the loose coins from the coin hopper and feeds the coins through a central feed aperture in the first rotating disk. A fixed disk lies below the first rotating disk and has a dispensing slot therein that receives the coins from the central feed aperture. The coins to be dispensed are lined up in a row in the dispensing slot from the center of the fixed disk to the periphery thereof for dispensing through an exit slot in the fixed disk. A second rotating dispensing disk lies below the fixed disk and spring biased pusher balls on the second rotating disk push on the edge of each coin to push coins from the center of the fixed disk down the dispensing slot. The dispensing slot in the fixed disk sits adjacent to a coin tray where the loose coins that have been dispensed are accessible to the patron.

  • Patent number: 4934982
    Abstract: Coins lying on a driven rotary plate are displaced by centrifugal force into a discharge channel limiting a permissible thickness of the coins by its height. At a roll-off lug, the coins fed from the discharge channel are rolled off in an S-shaped movement during handling by a conveyor belt acting from above, and are finally conveyed away in a straight direction. The S-shaped movement is forced on the coins by an arrangement of elements which limits an outlet opening. Such an arrangement has the effect of ensuring a reliable and troublefree individual separation of the coins with few moving parts.
