A sprinkler includes a riser, an impeller mounted in the riser, and a nozzle rotatably mounted at an upper end of the riser. A drive assembly including a reduction gear train couples the impeller and the nozzle. A friction clutch is located in the drive assembly between an output gear of the reduction gear train and an input gear of the reversing mechanism and provides a positive drive connection under a normal load and slips under an excessive load. An alternate embodiment utilizes the friction clutch in a rotor-type sprinkler in which the nozzle rotates continuously through a continuous 360 degree arc.

Friction clutch for rotor-type sprinkler

A sprinkler includes a drive mechanism mounted in a riser that rotates a nozzle at the top of the riser. The drive mechanism enables a user to select between oscillation of the nozzle through an adjustable arc and uni-directional full circle rotation of the nozzle. The sprinkler includes an automatic arc return feature that enables the nozzle to resume oscillation between a pair of original pre-set arc limits when the nozzle is twisted by a vandal outside of the arc limits.

Adjustable arc rotor-type sprinkler with selectable uni-directional full circle nozzle rotation

A sprinkler includes a drive mechanism mounted in a riser that rotates a nozzle at the top of the riser. The drive mechanism enables a user to select between oscillation of the nozzle through an adjustable arc and uni-directional full circle rotation of the nozzle.
