ABSTRACT:
An irrigation sprinkler which may include a pop-up assembly driven by a water-flow powered motor. A nozzle is mounted on the upper end of the pop-up assembly and is rotated through an adjustable arc to irrigate a sector of a particular size, and it is automatically reversed at the end points of the selected irrigated sector to oscillate back and forth across the sector. The sprinkler is constructed so that if the pop-up assembly is rotated forceably beyond its preset arc of coverage, either by vandals or others, the sprinkler itself is not damaged, but it will automatically reset itself into its previously preset arc of coverage.
