  • Patent number: 5106337
    Abstract: A coin sorter and dispenser includes side-by-side vertical coin chambers for sorted coins. The stacks of coins are supported on respective friction wheels which are exposed at the bottom so that a user may engage the bottom of a selected wheel and rotate it so that the top of the wheel slides the lowermost coin in a stack through an exit clearance to drop into the hand of the user. The friction wheels engage the stacks near the front edge and the rear edge of the stack is supported on sloping ramps to ensure that the lowermost coin slides forwardly through the clearance. Coins are fed through a top slot to be size sorted into the respective chambers. The sorter is formed of injection molded snap together front and back parts with a snap-on cover plate over the slightly inclined upper sorting portion of the front part. The front part is transparent so the number of coins in each chamber may be seen.
