ABSTRACT:
An adjustable part circle sprinkler assembly including a sprinkler body structure and a sprinkler head structure mounted thereon for rotational movement in either direction about an upright axis. An interior water flow path from an inlet in the body to a stream discharging outlet in the head includes nozzles directing streams onto a reversible flow directing mechanism for driving an impeller selectively in either direction. The impeller is connected with the head to rotate the same by a gear driven speed reducer and a slip clutch. A part circle pattern control assembly is mounted in an open top of the head closed by a conveniently removable anti-vandal cap structure. The pattern control assembly cooperates with a lever and resilient post reversing mechanism for the reversible flow directing mechanism. Manual movements of the head are accommodated by the slip clutch which protects the gear driven speed reducer. The control assembly serves to automatically return the head to operation within the selected pattern when moved manually therefrom.
