Abstract
A step-by-step rotary sprinkler having a combined stream coherency diffuser and distance control baffle member formed of sheet metal to include an arm portion disposed generally vertically having an aperture extending horizontally through one end thereof, a baffle portion bent outwardly at generally right angles from the opposite end of the arm portion and a relatively small diffuser portion bent outwardly at right angles from the free edge of the baffle portion and a manual engaging tab also bent outwardly at right angles from the arm portion, and a pivot assembly extending through the aperture to mount the arm portion on the sprinkler body for pivotal movement into any desired position of adjustment within a predetermined range wherein the radially outermost point of the member is disposed radially inwardly of the radially outermost point of the drive spoon, the positions of adjustment within the range including (1) a diffused only position where the diffuser portion extends into the stream when the drive spoon is out of stream engagement dividing the same generally vertically so that the stream is spread horizontally without the same engaging the baffle portion and (2) a diffused and baffled position wherein both the diffuser portion and the baffle portion extend into the stream when the drive spoon is out of stream engagement so that the stream is both spread horizontally and deflected generally downwardly.
