Abstract

Abstract Flat pad applicator includes a base member having a pair of laterally spaced apart tapered pins between which the hub portion of a handle is snapped into position for rotatably mounting the handle on the base member. The hub portion has a plurality of circumferentially spaced indexing notches in the outer periphery thereof which may be selectively engaged by an indexing locking rib carried by a cantilevered tongue on the base member for releasably locking the handle in any one of several angularly adjusted positions. The pad assembly itself includes a backing plate made out of a magnetic material to permit a magnet to be used for easy attachment and removal of the pad assembly from the base member for cleaning and/or replacement.
