ABSTRACT:
An improved range controlled rotary sprinkler of the type having an impact arm-nozzle assembly including a bearing spring mounted on a bearing nut-sleeve assembly. The improvement includes a cam plate, having an outer contour of desired shape, which is horizontally and rotatably mounted on the nut-sleeve assembly, and a lever with deflector and cam follower. The bearing spring is mounted over the cam plate to place a downward bias on the top surface of the cam plate. The cam plate is provided with a downwardly extending tab which is operable to engage a selected side of the nut-sleeve assembly. The cam plate may be positioned to control the directional range of water spraying from the nozzle by retracting the cam plate against the bearing spring, rotating the cam plate, and releasing the cam plate. The cam follower follows the contour of the cam plate to vary the pitch of the deflector to control the range of spray.
