ABSTRACT:
A pattern control or programming device for a lawn sprinkler having a nozzle-equipped body rotating or oscillating on a generally vertical axis and having a movable guide element for controlling the elevation of discharge of water from the nozzle. A cam having a variable cam surface contour is engaged by a cam follower which imparts movement to the guide element to vary the elevation of water discharge from the nozzle at desired positions of the nozzle during rotary or oscillatory movements of the sprinkler body. A cam mounting structure operates to hold the cam in desired set contours of the cam surface.
