PENCIL-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 760,749, dated May 24, 19.04. Application filed September 22, 1903, Serial No. 174,141.l (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. McFALL, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Pencil-Sharpeners, of whichthe following is a specification.

My invention relates to a new and useful improvement 1n pencil-Sharpeners, and has forv its object to provide a pencil-Sharpener which may be madefat a comparatively small price and yet will provide a Sharpener which is exceedingly durable and efficient and which will sharpen a pencil quickly and without soiling the hands.y

With these ends in view this invention coni sists in the details of construction and combinger and' supported by the second inger. The pencil is held down on a table or desk and 45 designed to be used as shown in Fig. 1.

Figure l is a .,-;perspective view of my im5 proved Sharpener in use; Fig. 2, aplan View of the same; Fig. 3, a section on the line 3 3 of Fig. 2.

The sharpenerrconsists of a Hat plate of steel stamped out in the form of an elliptical ring A, the inner edge at each end being beveled. and sharpened, so as to form cutting y edges, as shown at B. The ring is corrugated across its shortest diameter, as illustrated at C, so as to form a lateral grooveD upon each side. The concaved surfaces of these corrugations are roughened similar to a ile, so that the lead of the pencil maybe pointed by rubbing it in these grooves. The Sharpener Iis t is held between the thumb and first or index turned with one hand and drawing the sharpener gently over the pencil with the other hand, cutting as you would with a penknife.

With this Sharpener any shape point desired can be made, and the corrugations afford a firm grip of the Sharpener and also serve to hold the-Sharpener from lying Hat upon a fiat surface, so that it may be picked up easily at any time, and the corrugations also prevent,

I-Iavingy thus fully described my invention,

what I claim as new and` useful is* l. A pencil-Sharpener formed of a liat elliptical ring, the inside edges of the ring at each end of its longest diameter sharpened so as to form cutting'fedges, and roughened or filed surfaces formed upon each side of the ring, as and for the purpose specified.

2. A pencil-Sharpener consisting of a flat metallic ring, the inside edges of the ring at each end sharpened so as to form cutting edges, enlargements formed upon the ring at each. side of its shortest diameter, roughened or fiat surfaces formed upon each face of the ring, as and for the purpose specied.

3. A pencil-Sharpener consisting of a fiat elliptical metallic ring, the inside edges at each end of its longestdiameter sharpened to form cutting edges, corrugations formed in the end across its narrowest diameter, as and for the purpose specied. 1 y l' 4:. A pencil-Sharpener consisting of a flat elliptical metallic ring, the inside edges at eachend of the ring sharpened so as to form cut-v ting edges, corrugations formed in the .ring across its narrowest diameter, the concaved surfaces of said corrugations being roughened, as and for the purpose specified.

In testimony whereof I have hereunto af# fixed my signaturein the presence of two subscribing witnesses.
