UNITED STATES PATENT OEEICE.

JOHN MACMULLEN, OF NEW YORK, N. Y.

PENCIL-SHARPENER.

Specification forming part of Letters Patent No. 5 1,845, dated January 2, 1866.

To all whom it may concern.-

Be it known that I, JOHN MACMULLEN, of New York, in the county and State of New York, have invented anew and Improved Mode of Sharpening Pencils; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon.

The nature of my invention consists in providing boxes of three diiferent forms. i

N o. l is a box of any convenient size, in the center of which a detached portion rises up, and on this detached portion a file is securely fastened. The file a b, being entirely detached from the sides, allows all the filings to drop into the box, thus preventing any dirt from falling on the licor, desk, or table, or on any other place where this pencil-Sharpener may be used.

N o. 2 is a box of any convenient size, with a blade or cutter, c d, fastened securely at one end of the box, and so arranged that all the chips or cuttings may fall into the box, just as the filings do in No. l.

No. 3 is a combination of Nos. 1 and 2, and consists of a box of any convenient size, with a detached file, as in No. l, a b, and a knifeblade or cutter, c d, as in N o. 2, at the end, so that the wood part of a lead-pencil may be cut by the cutter and the point sharpened by the le.

A loose or false bottom may be attached to the center piece, so that when the box is fastened to a desk or otherwise the center piece and false bottom may be lifted out, bringing With them all the tilings or chips, and thus preventing the necessity of unt'astening the box.

What I claim as my invention is- 1. The isolation as well as the convenient form and arrangement of the file, and its combination with the dirt-box, as in No. 1.

2. The combination of the knife-blade or cutter with the chip-box, as in Figure No.2, so that the sharpening of pencils or crayons may not cause any dirt on the table or other place where it may be used.

3. The combination ofthe dirt-box with both the tile and the cutter, as in Fig. No. 3, for very often a different angle is required for the Wood from that required for the marking material, and this combination secures both of these, together-with the advantages of the dirtbox.

4. The modication ot making the boxes somewhat higher at the ends, so that books or papers may be laid upon the pencil-Sharpener' without receiving any soil from the ilin gs that may remain upon the file.
