UNITED STATES PATENT OFFICEe PETER R. ERLING, OF CHICAGO, ILLINOIS.

PENClL-SHARPENERn SPECIFICATION forming part of Letters Patent No. 263,776, dated September 5, 1882. Application filed January 23, 1882. (Model.)

To all whom it may concern: i

Beit known that I, PETER It. EELING, of Chicago, in the county of Cook and State of Illinois, have invented certain newand useful Improvements in Pencil-Sharpeners; and I hereby declare the following to be a full,

lclear, and exact description thereof, which will enable others skilled in the art to which my invention relates to make and use the saine, reference being had to the accompanying drawings, forming a part hereof, and in which- Figure 1 represents an inverted elevation of the device as seen from the back. Fig. 2 is a plan view of the same. Fig. 3 is a front view of the cover detached, Fig. 4 representing a front view of the Sharpener. Fig. 5 is an end view of Fig. 2 with the cover turned at Fig. 6 is an enlarged cross-seclionfof Fig. 2 on the line a: with a pencil, p, applied.

Like letters ofrei'erence indicate like parts.

The object of my invention is to produce a pencil-sharpener which shall eut the wood incasing the lead in a smooth and regular manner, and Without injury to the lead, and which may afterward be shaved and finally filed to thefinest and most desirable point Without danger of breaking the lead, and in which theknife can be resharpened and adjusted at pleasure, all as hereinafter more fully speciiied.

In the drawings, a represents the body of the instrument, provided with a blade having cutting-edge o, and file cut into the blade at d. Said blade is held in its place by thehook e1 at one end aud a set-screw, e3, at the other, pressing against it, threaded in the head e5, into which it may be conntersunk. The back of. the body is formed into an inclined plane, o3, upon which the blade o d rests, the edge e of which runs parallel with the sides of the body a. The end e5 has a notch, o2, which forms a stop for the lid b, provided with a corresponding notch, b2. The other end of the body a has a head, e', provided with a round .and solid part, e, through which a pin to hold the lid b passes, and upon which it turns. The lid has a stop or pin, b,which, when the lid is opened, strikes against the end e', and

the lid thus forms a handle for the apparatus.

The throat c in front of the knife is made wider at the outer end, as shown, so as to pass larger shavin gs, and for this purpose, and also for the further purpose of cutting shavings of varying thickness, the part in front of the knife is out back from the plane of the base o3, so as to form both an angle and an oifset'with it, and said oset is out deepest at the end on the line :v m and shallowest at the other end of the cutting-edge, as indicated at o2 and o.

When so constructed my pencil-Sharpener will 'eut large shavings when applied at its outer end, which may bel gradually reduced to finer asthe operation becomes more complete by applying the pencil p more toward the handle, Where nally quite a line shaving of wood and exposed lead is cut without danger of breaking the latter, whichl may then ultimately be finished with the le d.

Immediately over the parto o2 a knife-blade or eraser, to open and close, may be attached. It is shown open at o2 and closed at o3. A hook like the one shown at e may be attached to the head e5 to hold the other end of the blade o, and then one or two set-screws, as shown dotted in Figs. 2 and 5, may be passed through the inclined plane o3 to press against the under side of the blade and press it against said hooks, and thus hold it in place.

What I claim isl. Inapencil-sharpener, in combination with a combined knife and file, cd, the body a, having throat c', heads e @5,inc1ined plane o3, and cover b, substantially as specilied.

, 2. In a pencil-Sharpener, the body a, having inclined plane o3, throat o', and offset plane o o2, in combination with a knife, o, substantially as specified.

3. A pencil-sharpener consisting of the body a, provided with inclined plane o3 and adjustable combined file and knife c d, eraser o2, and cover b, provided with stud b', substantially as specified. 4. In combination with the adjustable knife and file 0 d, the body a, having throat c' and heads e and substantially as speciled.
