IMPROVEMENT IN PENCIL-SHARPENERS.
Specification forming part of Letters Patent No. 156,625, dated November 3, 1874; application filed July 20, 1874.
To all whom it may concern:
Be it known that I, WILLIAM A. YOUNG, of Jacksonville, in the county of Duval and State of Florida, have invented a certain Improvement in Pencil-Sharpeners, of which the fol-4 could be applied only to pencils of ordinary thickness, and to t them to larger sizes it was necessary to trim the pencil down with a knife.
My improvement consists in forming on the upper cylindrical end of the sharpener, which is preferably made of a single piece of sheetsteel, a small cutter, designed to' trim down pencils of unusual thickness in the act of littng the sharpener4 upon them, and to cut its own Way up as the pencil is decreased in length by use and pointing.
The drawing represents a perspective view of a pencil provided with my improved sharpener, Which is marked A. The main body of the sharpener is cylindrical, having a bore iitting the ordinarysized pencils, and being milled on the'outside to facilitate turning it when the pencil is to be pointed and sharpened. lts lower end, made tapering, as usual, con tains the customary slit, which terminates in an enlarged eye, and has one edge, a, slightly bent inward and ground to a sharp edge to form the cutter for pointing and sharpening the pencil. A gap, al, is formed in the upper cylindrical end, the edge c2 of which, running preferably at a slight angle to the axis of the sharpener, forms a cutter for trimming the body of pencils of more than ordinary thickness down to the capacity of the bore of the cylindrical part of the sharpener, so that it will not be necessary to first remove the sharpener and trim the pencil with a knife, so that the sharpener may slide upon it every time the pencil is to be sharpened. The cutter a? shaving oft' only to the extent of its required end motion every time the sharpener is` Operated, the appearance of the pencil will remain above the sharpener uninjured.
What I claim as my invention, and desire to secure by Letters Patent, is
Apencil-sharpener of the character stated, provided with a cutter, a2, at its upper end, substantially as and for the purpose specified.
In testimony whereof I have signed my nameto this specication in the presence of two subscribing Witnesses. y y,
WILLIAM A. YOUNG. Witnesses:
Jos. T. K. PLANT, B. EDW. J. EILs.
