ABSTRACT:
An electrically driven hand-held apparatus, for applying a treating material, such as wax, to a surface and for subsequently buffing up the surface or working the treating material thereinto, has a central applicator element surrounded by an annular buffing or brushing element, these elements being relatively displaceable axially so as to present one or the other in a projecting working position. The elements are rotatable by a bi-directional motor, and are coupled by an arrangement which ensures that reversing the direction of rotation automatically causes the relative axial displacement of the two elements. The applicator element may have a reservoir for the treating product, and a spring-loaded feed piston therein. The reservoir may have a valved inlet, and a stem may be inserted for filling the reservoir from an aerosol can. The applicator element and the buffing or brushing element may be removable and replaceable as an assembly.
