PENClL-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 295,296, dated March 18, lSl.

' Application filed October 24,1883. (no model.)

To all, whom it may concern Be it known that I, ALBERT M. SMITH, of the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Pencil-Sharpeners, of whi oh the following is an accurate description.

The nature of my invention consists in an improvement in pencil-Sharpeners, the object being to so construct it that it can be readily and easily resharpened, to facilitate the operation of sharpening the pencil, and to be enabled to bring it to a finer point, to avoid getting the hands and fingers soiled with the dust from it, and the danger of breaking it in so doing.

In the accompanying drawings, making a part of this specification, of which similar letters of reference indicate like parts.

Figures 1, 2, and 3 are front views, Figs. 4 and 5, sectional views.

A is the sharpener; B, the cap 5 O, the end for sharpening lead-pencils; D, for slate, and E the file-surface.

In order to enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The sharpener is made of any material that will afford asuitable cutting-edge, and in one, two, or more parts, and also the cutting portion of it, sidewise and edgewise, straight or curved, as shall be best adapted to the different purposesre'quired; but generally it is made of steel, andin two parts, having the cutting portion of it, sidewise and edgewise, straight, as shown in Figs. 1 and 2.

The end of the sharpener, 0, designed for sharpening lead-pencils is made to operate on theprinciple of a draw-knife, having its outting-edge on the inside of the curve, as at c, and the end, D, for sharpening a slate-pencil having its cutting-surface V-shaped and its outting-edge square, as at b b. On the body of the sharpener a file-surface, as at E, is made, for the purpose of sharpening the lead part of the pencil. This surface is made to cut down toward the point of the pencil in the ordinary way, or up from it, necessitating the teeth standing in an opposite angle, as shown, from what they would to cut in the other way, there by enabling a finer point to be made.

' be got at.

YVhen the sharpener is made in two parts, it is constructed as at Figs. 1 and 2, the parts being held together by a rivet or screw, as at c, the file-surface being so arranged as to come on the inside of each part, in order that the hands and fingers may not come in contact with it while being held to operate it, so as to become soiled with the dust and lead remaining on it, the ends of each part of the sharpener forming the end C being locked together, as at d, the other ends, forming the end D, be ing simply Qbrought close together, as at e. The parts are held in this position by catches on each part of the end D, as at ff, Fig. 2, so made as to lock together, as at 9, Fig. 1; or it is made as at Fig. 3, the two parts coming together in the center, as at k, and held in place by a cap, B, which also answers the purpose of protecting this arrangement of the file-surface, as in the former construction 5 or it is made as at Fig. at by only using one part of the sharpener, as shown, covering the file-surface with the cap B, as in Fig. 3, or using it without, as desired.

The sharpener is used on the lead-pencil by holding it with one hand against the desk, table,

or some solid object; or it can be held in the hand pressed against the person, to keep it steady. Then place the cutting-edge of the sharpener over the end of the pencil, and draw toward the person, continuing the operation until the wood part of the pencil is cut away sufficient to expose enough of the lead to form the point, as desired. Then by opening the sharpener, which can be done by springing the two parts of the end D apart a trifle, the filesurface is exposed so that the lead part can be sharpened on it, as desired.

The slate-pencil is sharpened by'drawing the point of the pencil through the aperture D toward its smaller end and against its outtin -edge on each side.

The cutting-edges of the sharpener can be sharpened the same as the ordinary knife, as by opening it exposes them so that they can Thus it will be seen the pencil can be sharpened with much greater ease and facility than in the ordinary way without getting the hands or fingers soiled with the dust and lead of the pencil, and without any danger of breaking the point; also, a much finer point can be made than when sharpened in the A and E, riveted together, having sharpening ordinary way. devices at each end, and an intermediate file- Having thus described my invention, now, 1 surface, all substantially as described. therefore, What I claim, and desire to secure by 3.
