3 Claims. (Cl. 15-257) This invention relates to wax polishing, bufling or abrading of lacquered surfaces, glazed or plated steel commonly used in automobiles, steel furniture, steel oflice equipment, steel walls and appliances such as refrigerators, stoves, washers or driers and the like, and of materials responsive to magnetic influences.

An object of my invention is to reduce the muscular force and effort required in the polishing, bufling or abrading of surfaces constructed of magnetizable materials or the like.

A further object of the invention is to permit the effective polishing of curved or irregular surfaces of magnetic material.

A feature of the invention is a polisher or the like containing magnets embedded in a flexible or articulated casing of non-magnetic material.

Another feature of the invention is a polisher or the like comprising flexible sections having magnets encased therein, whereby the attractive magnetic force holds the polisher firmly to a magnetizab-le surface and yet the polisher can easily be slid along the surface as it polishes.

' Another feature of the invention is an articulated pols Patent isher, having flexible casings for the magnets which are so tapered as to provide an effective hand grip for the operator.

'-In accordance with my invention, one or more magnets of such alloys as cobalt, nickel, steel or any combination thereof, also known as alnico or any other suitable magnetic material that will exert, and retain indefinitely, an attractive force of at least 16 ounces to 32 ounces or more per square inch of area, are encased within a durable envelope of rubber, plastic, wood, leather or cloth or any other non-magnetic suitable material or any combination thereof. The casing is articulated or arranged in segmented sections to provide for flexibility in one or several directions to allow it to follow contours of curved surfaces. The upper part of the casing with the included magnets forms an effective hand grip. One or several layers of a suitable material, such as cheesecloth are folded over the entire casing, and by gripping it firmly and rubbing lightly over the previously applied wax, bufling powder or abrading material applied to the magnetic surface, an easy and effective polishing may be accomplished. While it is necessary to exert from five to ten pounds of force to lift the device vertically from the surface, it is quite easy to slide it along the plane of the object to be polished without relaxing or diminishing the attraction of the magnets. By means of the magnetic forces involved, it is no longer necessary to press down hard against the metal surface since the magnets supply suflicient downward pressure to cause the wax to be well rubbed in, or to cause the buifing or abrading materials to remove desired surface layers of paint or dirt. Another important advantage of this construction is that the polisher device need not be laid aside when applying wax, polishing or abrading materials, but may be conveniently left adhering to the workice ing area, even on vertical members such as doors or sides of fenders and bodies within convenient reach.

For further comprehension of my invention and of the objects and advantages thereof, reference will be had to the following descriptions and drawings and to the appended claims in which the several novel features are more particularly set forth and enumerated.

In the accompanying drawing,

Figs. 1 and 2 are perspective views of the magnetic polishing device in accordance with this invention, with Fig. 1 showing it applied to an automobile,

Fig. 3 is a cross sectional view of Fig. 2 along a line 3-3 and showing the disposition of the magnets enclosed in the flexible casing,

Fig. 4 is a view taken along line 44 of Fig. 3,

Fig. 5 is a sectional view taken along line 5-5 of Fig. 3.

Referring to Fig. 1 of the drawing, the magneticpolisher device 15 of the invention is shown with a cheesecloth or chamois cloth 10 or the like wrapped around it for polishing a steel, iron magnetic material, such as the automobile body 5 and the like.

The magnetic polisher device 15, as-illustrated in Figs. 2, 3, 4, 5 consists of one or more magnets 12 of alnico or the like, each molded into a flexible rubber or plastic casing 11 to form articulated sections joined by an integral common flat base 13. Each section 11 is tapered upwardly from the flat base 13 and spaced from its neighboring section by a V-shaped depression to provide an effective flexible hand grip for the operator.

To polish enameled or lacquered steel surfaces, wax is first applied thereto by the operator. Several layers of cheesecloth 10 are then wrapped around the polisher device 15 as in Fig. l and over its bottom flat surface 13. The operator grips the polisher device by its upper flexible portion and in the customary manner rubs the wax to provide a polished surface. It is necessary only to move the polisher device 15 in a sidewise or rotary motion as the encased magnets 12 exert sufficient downward pressure on a steel surface to permit the Wax to be rubbed on effectively. It has been found that the magnetic polisher device 15 reduces considerably the muscular effort heretofore found necessary to obtain a high gloss finish. The device is likewise adapted for compounding with painters compound prior to polishing, or abrading surfaces with abrasive powders in a manner similar to that heretofore described.

The articulated sections 11 or a corresponding arrangement of segmented sections is capable of providing flexibility in one or several directions, whereby the magnetic polisher device 15 may follow easily the contours of curved or irregular steel surfaces, as for example, fenders of automobiles. The segmented sections may, if desired, be flat squares on top and bottom.

It should be understood that the polisher device disclosed may be used by means of a special holder in stationary or portable power driven equipment, which may oscillate or rotate the device over steel or other magnetic surfaces to be polished, buffed or abraded.

Further, the permanent magnets may be replaced by electromagnets which furnish the attracting force except that this species of device would be limited to areas where electric power is available, and by the length of the supply cord.

While I have described and illustrated the present and preferred embodiment of my invention, it is to be understood that -I do not limit myself to the exact construction herein described and disclosed, and reserve the right to make any changes and modifications regarding the size, strength, composition and number of magnetic materials as well as size, shape or composition of the encapsulating materials or any other such alterations that are within the scope of'this invention.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

1. A magnetic polisher device for waxing a magnetiz able. surface comprising a unitary molded, rubber casing having tapered segments spaced apart at their upper ends tov constitute a flexible hand grip, magnets imbedded in segments, and a flat non-magnetic, articulated base on said casing and joining said segments to act as a backing for a polishing cloth of like area, and to be slid easily over said surface Without altering the magnetic force appreciably, the magnetic force of said magnets being in the range of 1-2 pounds per square inch of flat base.

2. A magnetic polisher device for waxing magnetic surfaces comprising a unitary, molded casing of nonmagnetic, rubbery material formed into segments, trapezoidal in cross-section, a magnet embedded in each seg ment, and a flat non-magnetic articulated base integral with said segments for sliding over the magnetic surface wherein the magnetic force exerted by said magnets is in the range of 1-2 pounds per square inch to hold the casing to said surface transversely and permit the flat base to he slid laterally.
