ABSTRACT:
A golf ball dredge which comprises a shallow draft, buoyant support vessel in the form of a pontoon boat that provides a floating platform from which the dredging apparatus is supported. The pontoon boat has a small outboard motor mounted at its bow for providing a means for propulsion and steering of the boat. A relatively high pressure, gasoline powered, centrifugal water pump is mounted on the pontoon boat with its suction intake located below the water level. The pump provides a high pressure water outlet discharge that is supplied through eductor tubes into the inlet end of a bottom suction intake piping system. The bottom suction intake piping system also is supported on the pontoon boat with its inlet end submerged below the surface of the water to a suitable depth for lightly contacting the bottom of the waterhole. The high pressure water discharge from the pump is supplied through the eductor tubes to the inlet end of the suction intake piping system for creating a suction action that draws water and any entrained solids such as golf balls into the suction intake piping system. The suction intake piping system discharges under relatively high pressure water and any entrained solids into the inlet end of an automatically operable golf ball separator means supported on the pontoon boat for automatically separating out golf balls from liquid and other entrained solids contained in the suction intake piping system discharge without requiring the need for human intervention in the separating procedure.
