PENCIL-SHARPENER.

Application filed February 23, 1917.

To all whom it may concern Be it known that I, W ILLIAM C. CUTLER, a citizen of the United States, residing at North Glendale, in the county of Los Angeles and State of California, have invented new and useful Improvements in Pencil- Sharpeners, of which the following is a specification.

My invention relates to pencil sharpeners; and the objects of my invention are, to provide a sharpening device on a pocket holder for pencils; to cut the wood only of pencils while the lead is filed; to provide different and separate means for sharpening the wood part and for sharpening the lead part in a pencil; to provide the cutting blade on a spring like member on the device not -cutpressed upon; to provide a clasp fitting longitudinally slidably on a pencil with pencil sharpening means; the invention consisting in the construction, combination and arrangement of devices hereafter more fully described and claimed, and illustrated in the accompanying drawing, in

Figure 1 is a side view of my device.

Fig. 2 is a top view of my device.

Fig. 3 is a top view of my device slightly modified, the cutting blade being suitably spring member.

Fig. 4 is a front end view of my device.

Similar numbers refer to similar parts throughout the several views.

The body 1 of my device is made to easily 1 slip over a pencil. The end 2 of the body is provided with slots 3 making this end adaptable for difierent sizes of pencils. The other end of the body is provided with two projections 4 and 5. The projection 4 is o formed to allow the attaching of the cutting blade 6, and, at the farther end 7 of the lead sharpening means 8. The cutting blade 6 is placed on the projection 4 in an inclined position to the center line of the device as shown in Fig. 2, causing the cutting of the wood in a pencil in a natural manner from the outside toward the center in a downwardly direction toward the pointed end of the pencil.

The projections 4 and 5 are formed as spring members allowing a bending of these projections toward the center of the device, normally springing back to a position keeping the cutting blade free from the pencil. end 7 of the projection 4, a lead sharpening means is secured compris- Specification of Letters Patent.

ing a small file, emery cloth, or other suitable material.

Pressing the two projections 4 and 5 toward each other, brings the cutting blade 6 in engagement with the wood of a pencil, if such is inserted into the body 1 of the device, and, by turning the pencil, the wood is cut off in a similar manner as by sharpening a pencil with a common knife, instead of crosswise to the grains in the wood as in most of the other pencil sharpeners. Besides this, the springing capacity of the projections 4 and 5 allow the disengaging of the cutting blade from the wood any time it is desired, this making it possible to cut a long slender point or a short strong point just as desired, for a heavy hand it usually being desirable to have a short point on a pencil as this while the light hand of a draftsman prefers the long slender point as it lasts longer before it has to be resharpened, but which requirements usually cannot be fulfilled with pencil sharpeners now known.

Having cut the wood part of the pencil, the projection 4 with the cutting blade 6 is released, allowing the pencil to pass through the body 1 far enough that the lead part of the pencil comes below the sharpening means 8. Then the farthest end 7 of the projection 4 is bent until it comes in contact with the lead, and, by turning the pencil, the lead is sharpened; I prefer to sharpen the lead by other means than a knife or cutting blade, as these usually cause the lead to break, but, by using a small file, emery cloth or other suitable means, the lead can be sharpened more easily and to a better point as will easily be understood.

To prevent the cutting blade 6 from cutting too deep into the wood, the projection 5 is provided with a suitably shaped end 9 projecting past the lead coming in touch with the cutting blade after this has cut off the wood from the pencil leaving the lead in the pencil untouched.

A slight modification of my device is shown in Fig. 3, the cutting blade 6 being mounted in a slot 10 secured by small screws 11 to the projection 4, which, in this slight modification, is equally wide from the body 1 to the end 7 and so much stronger compared with the device in Fig. 2. At the same time, this slightly modified construction offers a certain protection to the user of the pencil sharpener, as the chips naturally pass does not break so easily, I

through the slot, and the user can keep the lingers out of the way.

More yet, by having the cutting blade mounted in the slot, the chips will naturally be equally and evenly cut, and, by providing slots 12 in the cutting blade, for adjusting the blade, the cutting of the cutting blade can easily be controlled.

After having sharpened the pencil, the device is slipped back on the pencil to form a clasp to hold the pencil in the pocket, the projection t forming the holder, while the projection 5 with the sharpening means rests behind the pencil opposite to the holder.

la ing thus described my invention, I claim 1. A pencil sharpener of the type described comprising a body fitting slidingly over a pencil having pencil engaging members formed on one end by having this end slit and having on the other end extensions formed on opposite sides normally project ing in a straight line from the body by the springing capacity of the extensions, one of the extensions forming a pencil holder when such pencil is carried in the pocket and the other extension forming the support for a cutting knife and pencil sharpening means.

2. A pencil sharpener of the type described comprising a body fitting slidingly on a pencil, an extension end on the body projecting 0d the body parallel to the center line of the body forming a pocket holder for the pencil when carried in the pocket, another extension end on the body also projecting oft the body on the same end with the first named extension end on the opposite side of the center line of the body, and sharpening means secured to the second named extension end adapted to cut and sharpen the pencil when the two extension ends are pressed toward each other.

3. A pencil sharpener of the type described comprising a body fitting slidingly over the pencil, an extension end formed on one end of the body forming a spring member, a cutting blade secured to the extension end for cutting the wood of the pencil, lead sharpening means also secured on the extension end beyond the cutting blade, the lead sharpening means and cutting blade being placed on the extension end adapted to be pressed toward the lead or wood of a pencil when so desired, and a second extension formed on the body on the same end with the first named extension on the opposite side of the longitudinal center of the body forming the counter part for pressing the extensions toward the pencil adapted to form a pencil holder when carried in the pocket.

at. A pencil sharpener of the type described comprising a body fitting slidingly over a pencil, an extension end on the body forming a spring member, a cutting blade secured to the extension end With the forward projecting cutting edge in a suitably inclined position to the longitudinal center line of the device pointing tangentially to the center of the device, the base of the cutting blade being normally held parallel or nearly parallel to the center line of the device, and a second extension end also on the body forming a counter spring part for pressing the cutting blade toward the inserted pencil.

5. A pencil sharpener of the type described comprising a body fitting slidingly over an inserted pencil, an extension end on the body forming a spring member, cut-ting means secured to the spring member, and a second extension end on the body forming also a spring member having a suitably formed end projecting in a U-shape over the sharpened end of a pencil toward the sharpening means on the opposite and first named extension end adapted to prevent the cutting means from cutting deeper into the wood of the pencil than desired.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

WILLIAM C. CUTLER.
