ABSTRACT:
A shower header type spraying device having an elongated spray header with a plurality of laterally-spaced nozzles and an elongated cleaning brush assembly supported in said spray header for cleaning inlet apertures of said spray nozzles. The cleaning brush assembly includes an axially extending rod and a plurality of brush elements each mounted on the rod by means of a self-aligning member that has an arcuate shape corresponding to the outer circumference of the rod for orienting a row of brush bristles of the brush element in predetermined relation to the elongated axis of the rod. The illustrated brush rod assembly includes a plurality of brush rod segments each having a self-aligning coupling at an axial end thereof such that joining of adjacent rod segments automatically orients the brush elements in predetermined angular offset relation to each other.
