Abstract
Abstract A coin sorting and counting system which comprises a rotatable disc having a resilient surface for receiving mixed denomination coins and imparting rotational movement to the coins; means for rotating the disc; a stationary sorting head having a contoured surface spaced slightly away from and generally parallel to the resilient surface of said rotatable disc, the sorting head including a wall for queuing the coins on the disc into a single file of coins, and a guiding edge which engages selected edges of the coins in the single file and guides the coins along a prescribed path where the positions of the non-engaged edges of the coins are determined by the diameters of the respective coins; a counting station along the prescribed path for separately counting each coin denomination before the coins are sorted; and a sorting station spaced circumferentially from the counting station, in the direction of coin movement, for discriminating among coins of different denominations and selecting coins of different denominations for discharge from the rotating disc at different locations around the periphery of the sorting head.
