  • Patent number: 4747478
    Abstract: A coin sorter is described for sorting coins of different denominations by means of ramps and flaps, the sorted coins being directed to different chutes, one chute being provided for each coin denomination, the chutes and coin exit openings at the ends of chutes as well as the ramps being formed in two complementary parts of the coin sorter. The sorter may be provided either in a coin operated assembly for use in an existing coin operated vending machine or in a new machine and in either case is best used in conjunction with a coin totalizer having a ratchet wheel, a price cam and at least two circular cams, the price cam and circular cams being rotatable with the ratchet wheel when the latter is rotated by a trip wire-lever, the degree of rotation being determined by the chute through which a given coin passes.
