ABSTRACT:
A water sprinkler develops any of several predetermined patterns of water coverage of regular or irregular shape and of varying sizes. The sprinkler includes first a plurality of pattern-defining apertures which are contoured to pass varying but predetermined amounts of water from a fixed sampling aperture as a sprinkler nozzle rotates in either or both angular directions about a vertical axis.
Pattern size is incrementally adjustable in one embodiment by a member having tapered apertures of varying sizes interposed between the fixed sampling aperture and the pattern-defining apertures. Pattern size and shape are finely adjusted by a parallel flow line including a valve for providing small additional or slightly reduced flow volumes. Rounded patterns are effected entirely through the parallel flow line.
