PENCIL-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 328,671, dated October 20, 1885.

Application filed December 3, 1884. Serial No. 149,396. (ModeL) To all whom it may concern.-

Be it known that I, AZEL HATCH, of Lexington, in the county of Fayette and State of Kentucky, have invented a new and Improved 5 PeneiLSharpener, of which the following is a full, clear, and exact description.

My invention consists in a convenient device for sharpening pencils operating upon the principle of a file 0r rasp, and includes a broad flat file with a beveled surface on either or both of its side marginal portions, the broad fiat surface being of a rough or coarse file-cut to rapidly shape or reduce the wood of the pencil, and the bevel surface or surfaces being of a much smoother or fine file-cut for the purpose of afterward bringing the lead or marking material to a fine point. The invention also includes a double or reversible construction of the device, with its opposite faces shaped and file-cut as described, and with a handle at each end of the device, and further includes in such double construction a reverse diagonal arrangement of the file-cuts on the opposite faces of the tool to adapt it for use by both right and left handed persons.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a perspective view of a pencil-sharpener embodying my invention, showing the samein its single form or as only provided with one end handle, and Fig. 2 a transverse section of the same. Figs. 3 and 4 are opposite face views of the device in its double form, or as provided with opposite end handles, and with the file-cuts on its reverse faces arranged to incline in opposite direc tions.

In Fig. l of the drawings the file-cut pencilsharpener is represented as provided with asingle end handle, I), forming an integral portion or extension of the body of the device, which is made of steel. lts body presents a broad fiat surface, 0, having a coarse file-cut, and a beveled surface side marginal portion, d, having a much smoother or finer file-cut. Either or both of its opposite side marginal portions may be thus beveled and cut. The

cuts or file-teeth are arranged obliquely or diagonally, pointing toward either end of the tool. Both faces of the device may be similarly cut, to give it an extended wear and greater use; or the one face may be left bare. In Figs. 3 and 4 of the drawings the device is represented as having its opposite faces file-cut, each face presenting a broad fiat surface, 0, having a coarse file-cut and a beveled side marginal portion, (1, having a finer file-cut. Said Figs. 3 and 4 also show the device as provided with two handles, 12, one at each end, and as having the file-cuts on its opposite faces in reverse directions to adapt the tool for use by right and left handed persons.

In using the tool the pencil to be sharpened 6 is held in the one hand and the tool or sharpener in the other. The pencil is then first rubbed, and turned or rolled while being rubbed, over the broad coarse-cut surface 0, which rapidly reduces the wood of the pencil, and is next afterward rubbed and rolled over or on the finer-cut beveled surface (I to bring the lead or marking material to a fine point, the inclination of the surfaced serving to form a convenient angular bearing for the reduced 7 end of the pencil while finishing the sharpening of it.

A file pencil-sharpener constructed as described will sharpen the softest pencil without breaking its lead or point, and will give as fine a point as can possibly be desired, and this in a rapid and easy manner. Furthermore, the pencil may be brought to a graceful finish at its point, and be readily kept so, and the fancy of the operator be fully satisfied. Such a pencil-shar 'iener will be found of great service to artists and very convenient and advantageous for school use. It is applicable, too, to any kind of pencil.

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

1. A file pencil-sharpener having a coarsecut broad flat surface and a beveled finer-cut side marginal portion on either or both of its faces, essentially as described.

2. A file pencil-sharpener having handles at its opposite ends and coarse-cut broad fiat snrfaces and beveled finer-cut side marginal handles in reverse directions on the opposite portions on its opposite faces, substantiallyas faces of the sharpener, essentially as and for [O specified. the purposes herein described.

3. A file pencil-sharpener having handles at its opposite ends and coarse-cut broad fiat AZEL HATCH surfaces and beveled finer-cut side marginal Witnesses: portions on its opposite faces with the file S. L. MINER,

cuts or teeth arranged to run oblique t0 the A. H. HATCH.
