COMBINED PENCIL SHARPENER AND INK ERASER. No. 391,522. Patented Oct. 28, 1888.

'UNITED STATES HENRY EDGARTON, OF SHIRLEY, MASSACHUSETTS.

COMBlNED PENCIL-=SHARPENER AND INK-=ERASER.

SPECIFICATION forming part of Letters Patent No. 391,522, dated October 23, 1888.

Application filed November is, 1857. Serial No. 255,552. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY EDGARTON, of Shirley, in the county of Middlesex and State of Massachusetts, have invented an Improvement in a Combined Pencil-Sharpener and Ink- Eraser, of which the following is a specification.

The object of my invention is to provide a cheap, simple, convenient, efficient, and durable pencil sharpener adapted to cut the wood of a common lead-pencil lengthwise of the grain of the wood and of a curved form of shaving, so as to leave the tapering point portion round and smooth and of any taper which may be desired, and also serve the purposes of an ink-eraser and pencil-point protector and rubber-eraser holder; and it consists in the construction of a thin sheet-metal or steel tube provided upon one side with an opening forming a cutting-edge, and an open beveled end portion adapted asan ink-eraser, as hereinafter more fully described, and specifically set forth in the claim.

Figure 1 represents a perspective view of my invention in position as an ink-eraser. Fig. 2 represents a longitudinal section of the same in position as a pencil-sharpener.

A represents a thin sheet-metal or sheetsteel tube, which may be cut out from a flat sheet of steel and provided near'one end with an opening, B. The curved side portion toward the end is bent inwardly and beveled or sharpened to an edge, P, which projects slightly from the interior surface of the tube A, so that when the sharpener is placed in a horizontal position and the end of a wooden lead pencil, D, be inserted within the open end thereof, as shown in Fig. 2, and pressed down on the projecting curved edge and then drawn outwardly, a thin curved shaving will be cut from the wood body of the pencil,which may be presented to the cutting-edge on various portions around the point end thereof, so as to reduce the same to the desired point. It

will be seen and understood that the taper to be formed at the point end of the pencil is governed by the angle at which the pencil is held in relation to the interior cutting surface or line of the tube, the shavings passing out at the said opening 13, and, as the same are cut off in a longitudinal direction of the pencil, there is no liability of breaking the point of the lead, as is frequently the case with those which cut crosswise or around the point, as heretofore and in common use, and which form afixed taper. The opposite side portion of the tube A is cut away on a curved bevel, as shown, and is so formed as to provide a sharp cutting-edge, E, which serves as an inkeraser, when held in position as shown in Fig. 1. The opposite end portion of the sheetmetal tube A may be provided with a rubber head or pencil-eraser, O, which will also serve the purpose of a point-protector when the pencil D is inserted and forced within the tube, which is formed of suitable size and 'slightl y tapering and being open or slotted at one side, so as to permit it to spring outward, so as to snugly fit upon the body of the pencil, and thus hold the same together temporarily when placed in the pocket or other receptacle of the user, or as heretofore employed with similar devices now in use.

I am aware of the English Patent No. 8,222, June 8,1887. Therefore I do not broadly claim a combined pencil-point protector and cutter, as embraced in the said patent, as it would not fully serve the purposes contemplated in my invention, which is adapted to cut away the wood of the pencil by means-of a segmental cutting-edge, which is so formed in. relation to the interior of the metal tube that it serves to gage the thickness of shavings out therefrom, whereby the concave cutting-edge leaves the pencil in better form for use, the: point or sharpened portion being left cylindrical instead of many irregular angular cut surfaces.

Having thus described my invention, what I claim is- The pencil-sharpener and ink-eraser consisting of the sheet-metal tube A, having the inclined curved edge E and provided with the opening B, from which slightly projects the segmental cutting-edge P, which conforms to the interior surface of the tube, as shown and described.

HENRY EDGARTON.
