Abstract

294,091. Steinbach, H. March 15, 1928. Pencil sharpeners.-In pencil sharpeners of the kind using a two-edged blade, more particularly a used safety-razor blade, the blade n is mounted upon a support g provided with a conical recess o into which one edge of the blade projects, while the ether edge protrudes through a slot in the flat upper surface of the support to enable the pencil to be trimmed upon it. The blade is held upon an inclined surface k by a plate secured by a nut m on a screw in the support. The device is preferably hingedly mounted upon a frame d secured within a box a provided with a hinged lid b, the upper edge e of the frame providing at one side a support for the pin upon which the member is hinged, and at the other side a seating for the member g. A chamber p for spare blades is provided in the body of the member g.
