Abstract

A coin cleaning device for separating foreign objects from a mass of coins, comprising first and second shelf portions arranged at first and second heights, vibration means for vibrating both the first and second shelf portions to cause coins on said shelf portions to be conveyed along said shelf portions, said shelf portions each being perforated by apertures of transverse dimensions smaller than a predetermined minimum diameter of coins to be handled by the device, whereby foreign matter of transverse dimensions smaller than the perforations can fall through said perforations, said first shelf portion having an upstream end and a downstream end, said second shelf portion having an upstream end and a downstream end, said shelf portions being arranged in series with one another whereby coins fall from said downstream end of said first shelf portion to tumble downwards to lie on said upstream end of said second shelf portion, and a coin outlet positioned beneath said downstream end of said second shelf portion whereby coins conveyed along said second shelf portion fall into said coin outlet.
