ABSTRACT:
A rotary brush includes a generally cylindrical, sheet metal core having fittings arranged to be inserted into both ends thereof for the reception of conventional brush drive means, e.g., a rotating drive shaft adapted to extend through the core or stub shafts which are adapted to extend only into the ends of the core. The fittings are comprised of an elastomeric material having a Shore scale A hardness within the range of from about 85-100, and the tubular core is provided with radially inwardly extending circumferentially spaced projections adjacent each end thereof which are adapted to slidably fit within axially extending grooves formed in the outer surface of the fitting and to resiliently engage the fitting to thus lock the fitting against relative rotation. The fittings, which are adapted to be snugly and resiliently secured to the aforementioned brush drive means, may be readily replaced when desired simply by sliding them out of the ends of the core.
