Title: Stream reversing director

Abstract: A stream director is disclosed adapted for mounting on a rotary sprinkler head to redirect the water stream during a segment of the rotation of the sprinkler from its intended portion of the irrigation area to another portion. A plurality of closed adjacent smoothly curved channels are employed to confine and redirect the stream emanating from the nozzle prior to its break-up whereby the spray pattern from the sprinkler is substantially as if the sprinkler were rotating through only a portion of a circular area.
