UNITED STATES PATENT QT'FIGE.

CHARLES D. SMITH, OF \VASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO IIIMSELF AND JOHN A. VVIEDERSHEIM, OF PHILADELPHIA, PA.

COMBINED ERASER AND PENCIL-SHARPENER.

Specification forming part of Letters Patent No. 58,558, dated October 2, 1866.

To all whom fit may concern:

Be it known that I, CHARLES D. SMITH, ot' the cityT and county ot' VashngtOn, in the Distriet of Columbia, have invented a new and usefulComhined Eraser and Pencil-Sharpener; and I do hereby declare the following to be a i'ull, clear, and exact description of the nature, construction, and operation ot the sam-c, reference being had to the accompanying drawing, which is made a part of this specilication, and which represents a perspective View, partly in section, ot' my improved device.

The object ot this invention is to combine as one the two instruments which have hitherto been employed separately, for the respective functions of erasing ink and sharpening pencils; and by this language my invention may be readily distinguished from erasers in which the blade or cutter is constructed with a tilegroove or a cutting-edge, especially designed t'or sharpening pencils. The pencil-sharpener, which constitutes an element ot' the present combination, consists of a conical metallic cutter-that is to say, a device having a conical ,interior essentially, and an internal knife,

straight, spiral, or of any other suitable form, and adapted by rotation to give the desired taper or conical form to the end of the pencil when introduced.

I construct an eraser by securing the erasing` knife or cutter A in one end of the handle B in any suitable manner. In the other end of this handle I insert, and secure in any desirable way, a pencil-Sharpener, C, which may be constructed in any manner, so long as it is adapted to receive the end of' the pencil and by rotation cut the same, so as to give it the required taper or conical form. The pencilsharpener, thus inserted, may have its edge or mouth iiush with the end ot' the eraser, if preferred, and, under any mode ot application, the end ot' the eraser may be strengthened by a metallic band or otherwise.

The coinbination may be effected in other ways, substantially the same as the method above described-as, for instance, the pencilsharpener maybe constructed with a threaded collar adapted to be screwed onto the end ot' the handle B, and thus permit the pencil-sharpener to project beyond the said handle. In the former case-*thatis to say, when the pencil-sharpener is inserted in the end ot' the haudie B-the latter is slotted, as at c, so as to allow thegehippings from the pencil to find ready egress i'rom the interior ot' the pencilsharpener while the latter is in opera-tion.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with an eraser, of a pencilsharpencr having substantially the characteristics herein specified.

CHARLES D. SMITH.
