ABSTRACT:
An oscillating wave type lawn sprinkler having a spray tube that is angularly oscillated about its axis by a spray tube linkage assembly that is driven by a water-actuated motor. The linkage assembly is coupled to the spray tube by a releasable coupling that disengages whenever the spray tube is subjected to an external force which exceeds a predetermined magnitude, thereby permitting the spray tube to angularly deflect out of its normal alignment. Normal alignment of the spray tube is restored by manually rotating the spray tube until the coupling is again engaged.
