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.

Dependent claims

In electrically operable apparatus for the application of a treating product and selectively for subsequent buffing up of the surface treated and the working of the treating product thereinto, having a working head comprising a central applicator element for the product to be applied, an annular rotary brushing and rubbing element disposed about said central applicator element, one of said elements being axially movable with respect to the other of said elements to permit bringing said one of said elements into an axially projecting working position, an electric driving motor, a rotary driving shaft coupled to said motor, one of said elements being coupled to said driving shaft, the improvement which consists in that:

a. said motor is adapted to be rotatable in a first and in a second direction, and
b. said two elements are coupled by a coupling system adapted to cause axial displacement of said one of said elements with respect to the other of said elements, in one axial direction and then in the other axial direction, as a result of reversing the direction of rotation of said element coupled to said driving shaft.
