Application June 3, 1949, Serial No. 96,962

The present invention relates to improvements in removers for corns and similar horny indurations and thickenings of the epidermisat the toes or for any other calluses.

One object of the present invention is the provision of a device of the character described which facilitates a smooth, effortless, and speedy grinding or abrading of a corn off a toe cr the like and which-while grinding off a corn-will wax and lubricate the area surrounding the corn, so that any injury or adverse effect upon the skin will be avoided.

Another object of the present invention is the provision of a device of the character described which is simple and inexpensive to manufacture, light in weight, easy to use, and highly efficient.

Still another object of the present invention is the provision of a new method of making the corn abrasive file.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred forms of the invention have been shown.

In said drawings:

Figure 1 is an end view of a preferred embodiment of my invention;

Fig. 2 is an end view of the partially completed device; and,

Fig. 3 is an elevation of a complete embodiment of my invention.

Similar reference characters refer to similar parts throughout the several views.

In the drawing the numeral I denotes a longitudinal body of cardboard, wood, plastic material, or the like, which preferably is tubular as in the instance shown, but which may be also of any other suitable shape and design. At the outer side of the body I there is an adhesive layer 2 of glue or the like, and a plurality of granular particles 3 of abrading'material, such as sand, emery, ground glass, corundum, Carborundum, iiint, pumice or the like is secured to the body I by the adhesive layer 2. VThe particles 3 are intermixed with and embedded into a soft layer 4 of wax, paraffin, or any other waxy or the like substance, so that the outer surface of the finished device is substantially smooth.

If the device is pressed upon a hard object, such 3 Claims. (Cl. 132-7624) as a corn 5 (Fig. 1) or the like the soft layer 4 recedes, allowing the sharp edges of the particles 3 to be brought into frictional engagement with the corn. The waxy substance I exerts a smoothening effect upon the skin, but does not interfere with the abrading effect of the granular particles 3.

I prefer to make my new and improved device in either one of the following ways: I provide the outer surface of the body I with an adhesive layer 2 and immerse it into a mass of granular material of the desired coarseness; then I allow the glue to dry so that the device appears as shown in Fig. 2; and after drying, I heat the article and roll it upon an even surface of wax, paraffin, or the like until the wax, paraffin, or the like adheres firmly to the device and surrounds the same. Or, I mix thoroughly the granular particles with Wax or paraffin particles, provide the body I with an adhesive 2, and roll the body in the mixture of the granular and the waxy particles; thereupon, the outer surface may be smoothed .by rolling the device on a hard, even surface.

Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having thus fully described my said invention,
