A rotary sprinkler comprising a supporting structure and a sprinkler head mounted for rotational movement on the supporting structure. The sprinkler includes an arc controller for controlling the magnitude of the arc through which the sprinkler head can rotate and an arc adjuster for adjusting the arc controller to thereby adjust the arc through which the sprinkler head can rotate. The arc adjuster includes an arc adjust member mounted for rotation with the sprinkler head and drivingly coupled to the arc controller to adjust the arc through which the sprinkler head can rotate and an arc adjust driver for rotating the arc adjust member. The arc adjust member includes a plurality of seals integral with the arc adjust member and a pointer for providing an indication of one end of the arc through which the sprinkler head can rotate. The supporting structure has a marker for providing an indication of the other end of the arc through which the sprinkler head can rotate, and the sprinkler head has indicia for use with the pointer for indicating the magnitude of the arc through which the sprinkler head can rotate.

Rotary sprinkler with arc adjustment device

A rotary sprinkler including a sprinkler head, a drive motor and a drive train drivingly coupled to the motor and to the sprinkler head so that the motor can impart rotational movement to the sprinkler head. The drive train includes a shifter drivable between first and second positions for reversing the direction of the rotational output of the drive train. A buckling column spring provides the energy to move the shifter between the first and second positions. A one piece seal is used to provide a plurality of separate annular seals as well as to assist in mounting one or more components of the rotary sprinkler.
