Patent number: 5647089Abstract: Plastic balls of the type used in recreational trampoline type pits are picked up by a hand held conduit and conveyed pneumatically to a sorting station where out of round balls are culled from the stream of balls to be washed.

Patent number: 5609173Abstract: A prewasher for sorting and soaking golf balls prior to entry into a ball washer has a tub for receiving the balls, a standpipe in the tub through which a stream of water moves the balls up out of the tub to deposit them in a track that carries only round balls to the ball washer. Broken balls and/or stones drop through openings in the track and are not delivered to the ball washer.Type: GrantFiled: June 9, 1995Date of Patent: March 11, 1997Assignee: Hollrock Engineering, Inc.Inventor: J.

Patent number: 5350260Abstract: A golf ball washer feeds wet balls into an air moving transport mechanism that drys the balls as they are carried to one of a number of dispensers. The wet balls move by gravity down an inclined infeed chute to a load station where each ball is supported on a flow disrupting ramp, and the transport conduit includes a necked down area at the load station which cooperates with the ramp to disrupt the air flow thereby avoiding the tendency of a spherical golf ball to remain suspended in the column of air rather than being moved downstream through the conduit. Each dispenser has an intermittently driven drum with radially outwardly open pockets to provide predetermined numbers of balls to a basket at the discharge station of the dispenser.Type: GrantFiled: April 13, 1993Date of Patent: September 27, 1994Assignee: Hollrock Engineering, Inc.Inventors: Richard H. Hollrock, J. Richard Hollrock

Patent number: 5332350Abstract: A driving range environment includes golf ball pickers to return the balls to a golf ball washer. The pickers are parked at a golf ball unload station where the balls are dropped through a grate onto a conveyor or chute for transport to the hopper of the ball washer. From the washer the balls travel through air filled tubes that dry the balls and transport the balls to dispensers where the golfer can again drive the balls at the range.Type: GrantFiled: December 15, 1992Date of Patent: July 26, 1994Assignee: Hollrock Engineering, Inc.Inventors: Richard H.

Patent number: 4805251Abstract: A golf ball washer has a cylindrical bristle brush rotatably supported in a rectangular tank to move the balls along a zig-zag dual track defined in the tank cover and in an insert provided in the tank. The balls move downwardly through a top opening in the cover and enter the dual track in end-to-end relationship. The track has segments oriented at oppositely inclined angles to abruptly shift the direction of motion of each ball and to accelerate each ball away from those following it.Type: GrantFiled: June 2, 1987Date of Patent: February 21, 1989Assignee: Hollrock Engineering, Inc.Inventor: J.
