NlTE STATES THEODOR O. L. SCHRADER, OF NEW YORK, N. Y.

PENCIL SHARPENER AND POINT PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 362,669, dated May 10, 1887.

(No model.)

To aZZ whom it may concern.-

Be it known that I, THEODOR O. L. Senna- DER, aresident of New York city,in the county and State of New York, have invented an Improvement in Pencil Sharpeners and Point Protectors, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings.

My invention relates to pencil sharpeners and pointprotectors; and it has for its object to make said device from one piece of sheet metal, as will be more fully hereinafter set forth.

In the accompanying drawings,Figure 1 is a plan View of one form of pencil-sharpener. Fig. 2 is an end view of the same. Fig. 3 is the form of blank from which the device shown in Fig. 1 is made. Figs. 4 and 5 are views of a modified form of pencil-sharpener, and Fig. 6 a view of the blank from which the same is made.

B in thedrawings representsa piece or blank of sheet metal, which has the offset i and open ing or indentation y'. This blank B is to be struck up on each side of the central line, b I), so as to iorin the two tapering cavities ZZ, corresponding to the taper of the point of a pencil. Serrations m m are cut in the walls of the cavities Z I, so as to form cutting-edges, which shave off the wood of the pencil when the latter is being sharpened. To form the pencilsharpener, the blank B is bent on the line b 1) until the two halves come together and form between them the conical recess 1 for the reception of the point of the pencil, and the offset z' is turned over the edge of the other half of the blank, securely holding the parts to gether. When the blank is thus bent, the indentation or opening y will be on one side of or near the end of the sharpener, which serves to determine when the pencil has been sufficiently sharpened, as the point of the lead in the latter case will project into the opening. This opening also allows the point of the lead to be dressed off with a knife, if necessary. In the form shown in Figs. 4, 5, and 6 the sharpener is shown as provided with two offsets, it, but only one offset need be used, as in Figs. 1 and 3.

In Figs. 4, 5, and 6 the openingj is shown as being a hole cut in the blank B; but this performs the same function as indentation j in the other figures, the mode of bending the blank in Fig. 6 necessitating the change.

The part of the blank which is not struck up forms a handle for operating the sharpener.

\Vhen I say that cutting-edges are formed in the walls of the cavities, I mean as distinguished from cutters formed along the edges of the metal, such being old.

Having now described my invention, whatI claim is- A pencil-sharpener, B, having the opening j, folded offset i, struck-up cavities Z, and series ofcutting-edgesm, formed in the walls of the cavities Z, the sharpener being made from a single piece of metal, substantially as de scribed.

THEO. O. L. SOHRADER.
