Abstract
A wobbling sprinkler head has a sprinkler head main frame having a nozzle base having a nozzle therein and at least one arm extending therefrom supporting a deflector supporting base. The nozzle base is attached to a water supply and has a water inlet for directing water through the nozzle and against a water deflector head. The water deflector head has a shaft movably riding in the deflector supporting base and has a water deflecting surface attached to one end of the shaft and positioned to deflect water being emitted from the nozzle and a counterweight attached to the other end thereof to dampen vibrations. The water deflecting surface has a predetermined shape to cause rotation of the water deflector head responsive to water being directed thereagainst and has a protrusion extending therefrom to force an initial tilt and wobbling action.
