Abstract
An improved oscillating sprinkler comprising a frame having a sprinkler tube mounted for oscillating movement on the frame. An inlet water housing is mounted on the frame and supplies water to the sprinkler tube. The sprinkler tube is driven in an oscillating path by a crank arm, and an eccentric gear mechanism driven by the water being supplied to the sprinkler tube is operably connected to the crank arm. The eccentric gear mechanism is constructed to provide a variable speed output that balances the varible speed output of the crank arm to provide a substantially uniform velocity of oscillating movement for the sprinkler tube. The sprinkler also includes a mechanism for varying the effective length of the crank arm to change the arc of oscillation of the sprinkler tube, and a slip clutch mechanism interconnects the inner end of the sprinkler tube to the housing to permit the sprinkler tube to be manually rotated to shift the spray pattern to one side or the other.
