Patent ID: 7850094

Claim:
An irrigation sprinkler rotor having a full-circle and a part-circle operation mode, the irrigation sprinkler rotor comprising: a housing with an inlet for receiving fluid for irrigation; a riser stem mounted to the housing and movable between a retracted position and an elevated position relative to the housing, the riser stem having a longitudinal axis therealong; a turret mounted for rotation relative to the riser stem; a drive mechanism for rotating the turret in one of a full-circle or a part-circle operation; at least a pair of arc stops disposed in a first operational plane relative to the longitudinal axis and mounted for movement with the nozzle turret; a shiftable transmission powered by the drive mechanism and operable to oscillate the turret in part-circle operation between the pair of arc stops; and a trip lever arranged and configured to be shifted in an axial direction from the first operational plane to a second operational plane, the second operational plane spaced an axial distance from the first operational plane; when the trip lever is positioned in the first operational plane, it is configured to be shifted by the arc stops in order to shift the transmission to oscillate the turret in part-circle operation; and when the trip lever is positioned in the second operational plane, it is configured so that the arc stops bypass the trip lever for rotation of the turret in full-circle operation.
