ABSTRACT:
A collection, washing and dispensing apparatus for lightweight balls. A pneumatic transport receives the balls and transports the balls to an elevated storage hopper which has an angled bottom surface terminating in a downchute for feeding the balls to a scrubbing element. The scrubbing element has a rotating drum mounted in a semicylindrical mating rack immersed in a fluid tight washtub. The opposing surfaces of the drum and rack are covered by a compressible pile to provide a friction engagement of balls between the drum and rack. The rotation of the drum urges the balls around the rack to an exit lip of the tub. A gravity feed race adjacent the lip carries the balls to a collection funnel. A sterilization spray is mounted over the race for spraying the balls. A pneumatic transport is connected to receive balls at the funnel for dispensing.
