After being sharpened the blade may be just as easily returned to its place within the opening 11 and by proper manipulation of the adjusting screw 21, be brought to the desired position.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of'tlie same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub-' joined claim.

Having described my invention, I claim: A pencil sharpener of the character de scribed, comprising a handle provided at one end with an enlarged head having a longitudinally extending opening formed therethrough which has one side wall thereof vertically inclined and provided with a screw-threaded opening arranged near one side of the longitudinal opening, a cutting this patent may be obtained for Copies of five cents each, by addressing the WashingtomD.
