ABSTRACT:
A coupling for removably affixing a brush to a rotatable drive shaft includes a drive hub affixed to the drive shaft, in which an axial projection having a cam surface is disposed on either the drive hub or the brush. The other of the hub and the brush defines a recess for accepting the projection and has a spring retainer affixed thereto. The projection and recess have an interfitting spline connection for preventing relative rotation between the drive hub and the brush. The cam surface is adapted to elastically spread the retainer to allow-the projection to be inserted within the recess. The retainer thereafter engages the shelf surface to prevent removal of the projection from the recess. The spring retainer is provided with tabs for elastically spreading the retainer to disengage the shelf surface and allow the brush to be easily removed from the drive hub.
