DEVICE FOR USE IN SHARPENING PENCILS- SPECIFICATION forming part of Letters Patent No. 770,053, dated September 13, 1904.

Application filed May 26, 1904:. Serial No, 209,821. (No model.)

To aZZ whom, it Wtay concern.-

Be it known that I, ALBERT DOUGLAS FAGRE- LIUs, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and 1mproved Device for Use in Sharpening Pencils, of which the following is a full, clear, and eX- act description.

The object of the invention is to provide a new and improved device for use in sharpening pencils with a knife, which is simple and durable in construction, cheap to manufacture, and arranged to permit convenient carrying in a pocket and to allow an accurate and quick sharpening of the pencil.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the improvement as applied. Fig. 2 is a plan view of the same. Fig. 3 is a plan view of the sleeve. Fig. 4 is a longitudinal sectional elevation of the same on the line A 4 of Fig. 3. Fig. 5 is a side elevation of the knifeguide. Fig. 6 is a longitudinal sectional plan view of the same on the line 6 6 of Fig. 5, and Fig. 7 is a perspective view of the improvement mounted on a stand.

The device for use in sharpening pencils with a pocket-knife or any other suitable knife consists, essentially, of a sleeve A and a knife-guide B, mounted to turn on the sleeve A, the latter being adjustably and removably held on the pencil O to be sharpened.

The sleeve A consists of a cylindrical body A, adapted to slide loosely on the pencil O and formed at one end with integral springprongs A pressing against the sides of the pencil to hold the sleeve A against accidental.

movement on the pencil C, but to allow the operator or user to shift the sleeve, and with it the guide B, along the pencil to bring the guide into proper position on the pencil for sharpening purposes, as hereinafter more fully described.

One end of the body A is formed with an annular flange or shoulder A", and a similar shoulder A forms the junction between the body and the prongs A The free ends of the clamping-prongs A are preferably bent outwardly to form a flaring mouth A to allow of conveniently slipping the sleeve on the pencil.

The guide B consists, essentially, of a cylindrical body B, mounted externally on the body A of the sleeve, so as to allow the guide to turn on the sleeve, the longitudinal movement of the body B on the body A being limited by the flanges A and A*, as will be readily understood by reference to Figs. 1 and 2.

From the body B of the guide B extend integrally guide-fingers B B having their edges formed with flanges B, the edges and flanges being formed with tapers B and B of which the tapers B are preferably somewhat longer than the tapers B as will be readily understood by reference to Figs. 1 and 5. The free ends of the fingers B terminate in points, it being understood, however, that the opposite edges of the fingers B are in alinement, so as to form a proper restingplace for the blade of a knife to pass over in cutting off the wood from the pencil, as will be readily understood by reference to Figs. 1 and 2.

When it is desired to use the device, the sleeve A, with the guide B mounted to turn thereon,is slipped onto the pencil O, as plainly shown in Figs. 1 and 2, and moved to such a position that the terminals or pointed ends of the guide-fingers B are opposite the corresponding end of the pencil to be sharpened. The operator now uses a knife and draws the same down over the corresponding tapering edges 13* or B according to the length of the point to be made on the pencilthat is, for a long point the operator uses the tapering edges B and for a short point the knife is drawn down over the tapering edges B The operator in drawing the knife down over the tapering edges B or B cuts the wood of the pencil, and as the operator can turn the guide B around on the sleeve A while the latter is held stationary it is evident that the entire end of the pencil can be readily sharpened to form an accurate point without danger of breaking the lead of the pencil. It will also be seen that by the arrangement described the operator does not soil the fingers in sharpening the pencil, as is so frequently the case in sharpening a pencil with a penknife, as heretofore practiced.

The device is very simple and durable in construction, can be cheaply manufactured, and can be readily slipped at any time in position on the pencil for sharpening the point, and after this has been done it can be removed and placed in a pocket or other place until again required.

By providing the edges with the flanges a broad surface is provided. for the knife to readily slide on without danger of dulling the knife used for sharpening the pencil, it being understood that the said flanges follow the taper of the edges, and the flanges may extend either inward, as shown, or outward.

If desired, the pencil-sharpener may be mounted on a suitable stand D, screwed or fastened. on a table or other suitable support, or provided with a heavy base for the stand to act as a paper-weight. On the upper end of the stand I) is arranged a clamp E for screwing and clamping the tubular body B of the guide B to hold the latter against turning. In using the device the pencil inserted in the sleeve is turned, the sleeve turning in the tubular body as a bearing, and the operator uses the knife along the edges and flanges 13* or B of the fingers B of the now stationary guide, as above described.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. A device for use in sharpening pencils, comprising a sleeve for removable and adjustable attachment to the pencil to be sharpened, and a knife-guide having oppositely-disposed guide-fingers, the guide and sleeve being mounted to turn one on the other.

2. A device for use in sharpening pencils, comprising a sleeve for removable and adjustable attachment to the pencil to be sharpened, and a knife-guide provided with oppositelydisposed tapering fingers, the guide and sleeve being mounted to turn one on the other.

3. A device for use in sharpening pencils, comprising a sleeve for removable and adjustable attachment to the pencil to be sharpened,

f and a knife-guide provided with oppositelydisposed fingers having tapering edges, the

guide and sleeve being mounted to turn one on the other.

a. A device for use in sharpening pencils, comprising a sleeve for removable and adjustable attachment to the pencil to be sharpened, and a knife-guide provided with oppositelydisposed fingers having tapering edges, the taper on one edge of a finger being longer than that on the other edge, the guide and sleeve being mounted to turn one on the other.

5. A device for use in sharpening pencils, comprising a sleeve having clamping-prongs for adjustably holding the sleeve on the pencil, and a knife-guide provided with oppositelydisposed fingers having tapering edges, the guide and sleeve being mounted to turn'one on the other.

6. A device for use in sharpening pencils, comprising a sleeve having a tubular body and spring-prongs extending integrally from one end of the body to hold the latter adjustably and removably on the pencil to be sharpened, a knife-guide having a tubular body engaging the tubular body of the said sleeve, and oppositely-disposed fingers extending integrally from the tubularbody of the guide, the fingers having flanges at their edges, the latter being tapering.

7 A device for use in sharpening pencils, comprising a sleeve having a tubular body and spring-prongs extending integrally from one end of the body to hold the latter adjustably and removably on the pencil to be sharpened, a knife-guide having a tubular body engaging the tubular body of the said sleeve, and oppositely-disposed fingers extending integrally from the tubular body of the guide, the fingers having flanges at their edges, the latter being tapering, the sleeve being provided with annular shoulders for limiting the longitudinal movement of the tubular body of the guide on the said sleeve.

8. The combination with a stand having a clamp, of a knife-guide clamped on the said clamp and provided with a bearing and oppositely disposed fingers having tapering flanges, and a sleeve mounted to turn in the bearing and provided with means for engaging and holding the pencil to be sharpened.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
