Abstract
A visually interesting coin sorter and bank receives a group of random coins in a coin receiving chamber and ejects the coins one-at-a-time to roll to the bottom of a rotatable transparent spiral elevator plate or wheel. The spiral wheel lifts the rolling coins toward the center of the wheel until caught by size restrictions in the spiral to be then moved through an arc and to drop through a proper slot to form sorted stacks of coins. The spiral wheel is driven through an electric motor which is automatically turned on as soon as one or more coins are dropped in the chamber. Aftet the last coin is sorted the motor is automatically turned off. A coin sensing lever in the coin receiving chamber releases a cycle timer to close a switch to start the motor. The rotating spiral wheel drives an ejector slide to eject the coins one-at-a-time from the chamber. When the last coin is ejected the lever sensing the absence of a coin engages the cycle timer which is driven by the wheel to turn the motor off after such last coin is sorted.
