ABSTRACT:
An adjustable circular brush having a variable effective working diameter comprising a brush having radially projecting flexible bristles and an annular sleeve having a diameter less than the diameter of the bristles; the sleeve being selectively, axially movable between a first position in which the sleeve is retracted away from the bristles of the brush so that the bristles project freely in the radial direction in order to establish a maximum effective working diameter for the brush, and a second position in which the sleeve is extended to at least partially surround the brush so that the bristles are compressed in order to establish an effective working diameter for the brush which is less than the maximum effective working diameter. The brush is particularly suited for cleaning the points in the interior of a distributor cap and may be adjusted to clean various sizes of distributor caps.
