METHOD OF AND APPARATUS FOR SHARPENING ELECTRIC RAZORS AND THE LIKE Filed June 15 1940 Patented Mar. 16, 1943 UNITED STATES PATENT METHOD OF AND APPARATUS FOR SHARP- ENING ELECTRIC RAZORS AND THE LIKE Arthur J. Roderick, Portland, Maine, assignor to OFFICE Electro-Sharp Mfg. 00., Portland, Maine, a

3 Claims.

This invention relates to a method of and apparatus for sharpening small cutting devices such as electric razors and the like.

It is an object of the invention to provide an efficient sharpening device which is convenient in size and shape and can be readily kept at hand where needed or carried about when traveling.

According to the invention, a finely divided abrasive substance is suspended in a suitable oil. A container of convenient size and shape is provided, this container having a felt pad therein which is saturated with sufficient oil to exude some of the oil when lightly'pressed. Such pad may be in a single layer or a plurality of layers as desired. When not in use, the felt pad retains the oil and prevents it from escaping from the container.

For a more complete understanding of the invention, reference may be had to the following description thereof, and to the drawing of which Figure 1 is a perspective view of an embodiment of the invention, showing an electric razor applied thereto.

Figure 2 is a transverse sectional view of the invention shown in Figure 1.

A container of suitable size, shape and material may be provided, this container having a length or diameter of sufficient size to receive the cutting head l2 of an electric razor M or similar instrument to be sharpened. As shown on the drawing, a circular container is provided by way of illustration, but it can just as well be in rectangular form. The container may be of metal, of molded plastic, or of any other suitable material. The container is preferably supplied with a removable cover it which may be frictionally attached to the container H) or may be secured thereto by other means. Within the container is a resilient pad [8 of absorbent ma terial such as felt which, as indicated in Figure -2, is preferably in two layers and is horizontally supported on the bottom of the container. This pad is thoroughly saturated with suitable oil, a mineral lubricating oil being satisfactory for the purpose. Suspended in the oil is a quantity of finely divided abrasive material such as carborundum dust or an equivalent. This pulverulent abrasive may be distributed throughout the oil before the oil is introduced into the felt pad, or may be deposited on the pad before or after oil is supplied thereto to saturate the pad.

Sufficient oil is employed to exude from the felt when the latter is pressed.

In using the sharpener, the electric razor or other implement to be sharpened is connected for operation, and the cover of the container is removed. While the razor is in operation, the cutter head is pressed lightly against the surface of the pad and held there for a sufficient interval of time. The light pressure of the cutter head against the felt causes oil to exude from the felt and to enter between the moving cutter element and the guard of the razor. The pressure of the head against the felt also holds the guard firmly against the cutting element. As the oil contains finely divided abrasive, such abrasive is carried into intimate contact with the guard and moving cutter teeth, causing the cutter to be quickly sharpened. The razor is then removed and the cutter head cleaned, after which the razor is ready for use.

It is evident that various modifications and changes may be made in the embodiment of the invention herein shown and described without departing from the spirit or scope thereof as defined in the following claims.

What I claim is:

1. A device for sharpening electric razors and the like, which comprises a container, an absorbent pad of substantial thickness horizontally supported on the bottom of said container, a quantity of oil in said container substantially saturating said pad, and pulverulent abrasive material distributed through said oil.

2. A device for sharpening electric razors and the like, which comprises a container, an absorbent pad consisting of a plurality of layers of felt of substantial thickness horizontally supported in said container, sufiicient oil in said container to saturate said felt so that light pressure on the top of said pad will cause oil to exude, and pulverulent abrasive material distributed through said oil.

3. A method of sharpening electric razors and the like, which comprises pressing the cutting head of the razor against a horizontally supported absorbent pad saturated with abrasivebearing oil to compress said pad and cause oil to exude therefrom, and operating the razor mechanism while the cutting head is so pressed in the exuded oil.
