SPECIFICATION forming part of Letters Patent No. 582,078, dated May 4, 1897.

Application filed J 1 118 20, l 896.

T0 aZZ whom it may concern:

Be it known that 1, CHARLES MoOARRIQK, of Tivoli, in the county of Dutchess and State of New York, have invented newand useful Improvementsin Pencil-Sharpeners, of which the following is a full, clear, and exact d.e-

scription.

My invention relates to improvements in pencil-Sharpeners, and has for its object to combine with a sharpener proper a suitable guide or holder for the lead of a pencil, so that a true point may be readily obtained.

The improved pencil-sharpener is particularly adapted for use in connection with pencils comprising a suitable casing and a lead adj ustably held therein.

The invention will be fully described hereinafter and the features of novelty pointed out in the claims.

Reference is to be had to 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 plan View of the blank from which thebody of the holder is formed. Fig. 2 is a front View of the said holder. Fig. 3 is a side View thereof. Fig. 4 is a perspective View of a collar adapted to be inserted in the holder and serving as a guide for the sharpener proper. Fig. 5 is a perspective view of the sharpener proper. Fig. 6 is a front elevation of the complete device. Fig. 7 is aside view thereof; and Figs. 8, 9, and 10 are sectional plans taken on the lines 8 8, 9 9, and 10 10, respectively, of Fig. 6.

The improved pencil-sharpener consists, mainly, of three parts, namely, the sharpener proper, the holder for the sharpener, which also forms a guide for the lead of the pencil, and a ring or collar secured to the holder and adapted to receive one end of the sharpener proper.

The holder is made of a strip of sheet metal, such as shown in Fig. 1, said strip having a rounded portion A at its center with an aperture A. The strip is adapted to be folded along the lines ca a, forming thereby a central or head portion A At a predetermined dis tance from the said central portion the strip is provided with apertures A for a purpose stated hereinafter. A second bend is made in the strip at points indicated by the lines Serial No. 596,277. (No model.)

b l), forming between the lines a ct and b b the side portions A. Between the apertures A and the lines I) b the side portions A are provided with oblong apertures A Exteriorly the lines I) I) and c c are bent toward each other, so that the two semicircular recesses A will form an approximately circular aperture, as shown in Fig. 10. The strip is then return-bent above and along the portions A and a further bend is made adjacent to the side members A on the lines cl 61, forming return portions A between the lines o c and (Z (Z. The ends of the strip are formed with notches or recesses A whose sides extend approximately at an angle of forty-five degrees to the longitudinal axis of the strip. The two notches when brought together, as shown in Figs. 2 and 6, form a square, the sides of which are approximately equal to the diameter of the lead. Between the bend made on the lines at d and the ends the strip is bent inward at e e, forming loose longitudinal members A and transverse end members A forming a yielding lead holder. The longitudinal members A are slitted, forming on each a tongue A which is bent into the form of a handle, as shown in Fig. 2, said handle projecting through the apertures A of the side members A The sharpener proper consists of a body B, having a longitudinal conical bore 13 and a v segmental recess B in which is set the sharpener-blade O. The said blade, instead of ranging parallel to the axis of the sharpener, is arranged obliquely thereto, as will be seen best in Fig. 5. The upper end of the sharp ener is provided with a milled head B which has a screw-threaded aperture 13 into which is adapted to fit a screw D, which passes into the central aperture A of the holder. A

washer E is interposed between the head B and the central portion A of the holder.

The lower or free end of the sharpener fits into a collar or sleeve F, which is provided with projections F, forming clips to hold the said collar or sleeve on the holder, the said projections being inserted through the holes A in the side members A of the holder.

The operation of my improved sharpener is as follows: The pencil is introduced from the end of the holder opposite to that carrying the sharpener proper, so that the lead G will project into the bore 13' of the sharpener and will engage the notches A of the transverse end members A while the case H will be engaged by the curved walls of the recess A The lead is then pointed by turning the milled head B so that the blade 0 sharpens the pencil in the ordinary manner.

It will be observed that the lead is held firmly and in an invariable position relatively to the sharpener. It will also be observed that the guide formed by the members A A", and A is located in advance of that end of the sharpener into which the lead is adapted to enter-that is, the lead is engaged by the guide before it enters the sharpener. The sharpener proper may be readily removed by removing the screw D and the washer E, whereupon the sharpener may be slid longitudinally on the holder until it comes out of the sleeve F.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a holder having a pencil-guide at one end, a rotatable pencilsharpener at the other end of the holder, and a ring or collar secured to the holder and adapted to receive that end of the sharpener which is nearest the pencil-guide, substantially as described.

2. A pencilsharpener, comprising a holder formed of a strip bent into rectangular form, said holder having a pencil-opening at one end and provided with inwardly-projecting and recessed members spaced from the end formed with the pencil-opening and forming a lead-holder, substantially as described.

3. A pencil-sharpener, comprising a holder formed of a strip bent into rectangular form, said holder having a pencil-opening at one end and provided with inwardly-projecting members spaced from the end having the pencil-opening and having recessed ends forming a lead-holder, and a sharpener mounted in the opposite end of the holder, substantially as described.

4:. In a pencil-sharpener, the combination of a holderhavin g spaced and alined openings at one end, a ring secured in the holder, a sharpener having its lower end fitting in the said ring and a screw passing through the holder into the body of the sharpener, substantially as described.

5. In a pencil-sharpener, a holder formed of a centrally-apertured strip bent at each side of the aperture to form an end and two side members, the lower portions of the side members being bent inwardly toward each other, then return-bent, then bent upwardly approximately parallel with the side members and then bent inwardly, the inwardlybent portions being provided with opposite recesses forming openings, substantially as described.
