ABSTRACT:
A rotary brush construction, particularly for washing vehicles, having a pair of spaced collars mounted upon a shaft and supporting a plurality of elongated bristle holding members arranged in a cylindrical pattern concentric with the shaft. Each collar has an annular flange extending axially thereof, which flange has a plurality of circumferentially spaced slots extending axially inwardly from the free end thereof. The flanges of the collars are directed so that the slots formed in the plurality of collars all open axially in the same direction. Each bristle holding member has fastening elements, such as threaded fasteners, mounted on and positioned so as to be slidably received within a corresponding slot formed on a collar for permitting the bristle holding member to be fixedly secured to the collar. Since the slots all open in the same axial direction, the bristle holding members can be removed by loosening the threaded elements and then sliding the member lengthwise in a direction substantially parallel to the axis of the shaft. The bristle holding members can similarly be remounted on the collars in the reverse manner to that described above.
