Abstract: The ferrule of a bristle brush includes an annular bead peripherally about the ferrule proximate one end thereof, and the bead has a sufficiently large cross-sectional profile and circumscribes a volume having a sufficiently large cross-sectional area relative to the cross-sectional area of the volume circumscribed by the major tubular extent of the ferrule in order to permit expansion of that part of the bristle hold located in the volume circumscribed by the bead. A hardenable liquid adhesive material poured into the ferrule after the bristle is positioned therein will permeate appreciably into the hold of the bristle thereby substantially to encapsulate the same and to secure the filaments thereof tenaciously to the ferrule.

Abstract: Roller cover support consists of blow molded sleeve having plural protruding ribs to frictionally retain the roller cover in place. The ends of the sleeve are molded to receive and mount end caps thereon which include suitable bearings for the roller frame shaft and provide some support against collapse or flattening out of the sleeve during use under pressure. The O.D. of the end caps and adjacent ends of the sleeve are slightly smaller than the I.D. of the roller cover for normal concentricity and guidance of the roller cover onto the sleeve, and the ends of the ribs are tapered to wedge the roller cover on. When the roller frame shaft extends all the way through the roller support, perforations may be placed along the length of the sleeve to provide for drainage of any water or other liquid that may seep into the interior of the sleeve through the end cap bearings during clean up.
