Abstract

A reversible, adjustable arc sprinkler head comprising a sprinkler body incorporating a fixed nozzle; a spray plate mounted on one end of a support cage for rotation with the support cage in one or the other of two opposite directions about a first axis arranged coaxially with a stream emitted from the nozzle, and for back and forth tilting motion about a second axis perpendicular to the first axis, an opposite end of the support cage secured to a sleeve rotatably mounted in the sprinkler body, the spray plate having a pair of substantially parallel grooves for selectively receiving the stream, wherein the direction of rotation of the spray plate about the first axis is determined by the tilting motion of the spray plate about the second axis; and a shift lever formed with an aperture sized to receive the stream, the shift lever mounted at one end on the sleeve for rotation about a third axis parallel to the first axis, the shift lever enabled to shift the stream from one of the pair of grooves to the other of the pair of grooves to thereby reverse the direction of rotation of the spray plate.
