ABSTRACT:
An extendable-bristle brush having a hollow, tubular handle containing a folded bundle of fibers, the free ends of the fibers extending from an open end of the handle as bristles. The bundle is formed by folding a half-bundle of fibers about a hooked drawpiece and drawing the fold of the bundle into the handle so that both ends of each fiber protrude from the same end of the tubular handle to form the bristles of the brush. Folding of the bundle creates a bulge in the bundle which is slightly larger than the inner diameter of the tubular handle. Drawing the bundle into the handle compresses the bulge, resulting in a holding force which frictionally locks the bundle within the handle. The bundle may be advanced by pulling out the exposed bristles. As the bundle is repeatedly pulled out and cut off for additional uses, the holding force does not change significantly with shortening of the bundle or the handle. The handle is preferably resilient and may be corrugated into a bellows, the perstaltic extension and contraction of which can expose new bristles. The bellows also permit the handle to be bent so that the brush may be used in awkward situations. A plurality of individual brushes may be ganged to provide a larger brush.
