SHARPENING DEVICE I Filed Dec. 51, 1954 Inventor ,6 J. a f F-Q/ fIy j/Er/ Attorney Patented May 7, 1935 UNITED STATES PATENT OFFICE 1 Claim.

This invention is a device for sharpening the blades of hair cutting machines, such as hair clippers, and. is adapted for use in grinding or sharpening the blade of either electric or hand operated hair clippers.

An object of the invention is to provide a device of this character characterized by simplicity of construction and economy of parts.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawing wherein:

Figure 1 is a top plan view of the device.

Figure 2 is a longitudinal section view taken substantially on the line 2-2 of Figure 1.

Figure 3 is a transverse sectional view taken substantially on the line 3-3 of Figure 1.

Referring to the drawing by reference numerals it will be seen that the device comprises a substantially rectangular frame 5 formed of wood, metal or other suitable material in which is fitted and secured in any suitable manner, a base block 6. The block 6 is disposed at an incline to present at opposite sides of the device sloping surface I. Resting on and secured in any suitable manner to each surface I of the block 6 is a sheet 8 of emery paper or any other suitable material.

Also disposed at opposite sides of the block or base member 6 are longitudinal dividing strips 9 that have beveled or sloping edges to conform to the slope of the base member 6.

From the above then, it will be seen that the device is substantially the same at either side thereof presenting at both sides two elongated 5 chambers of a width suitable to accommodate the blade of hair clippers.

In use, the blade of the clippers to be sharpened is removed from the clippers and the teeth of the blade are placed against the selected 10 abrasive surface 8 and the blade moved downwardly from the upper to the lower end of the abrading surface. This operation is repeated any desirable number of times until the cutting edges for the teeth are obtained. 15

As is thought obvious, when a sheet 8 becomes worn and of no further use, it may be readily replaced with a new sheet.

Having thus described the invention, what is claimed as new is: 20 A device of the character described comprising a substantially rectangular frame, a plate member combined within the frame and disposed at an incline, an abrasive sheet covering each side of the plate member, and longitudinal dividing 25 strips arranged in the frame at opposite sides of the plate member and spaced equi-distantly inwardly from opposite sides of the frame.
