PENCIL-SHARPENEE.

Specification of Letters Patent.

Application filed June 28, 1909.

Patented July 26, 1910. Serial No. 504,857.

To all whom it may concern:

Be it known that I, EDWARD B. WELLns, citizen of the United States, residing at Asheville, county of Buncombe, and State of North Carolina, have invented certain new and useful Improvements in Pencil- Sharpeners, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a pencil sharpener, and particularly to a structure provided with a shaving knife mounted to cut longitudinally of the pencil.

The invention has for an object to provide a novel and improved construction whereby the pencil holder is provided with a shaving blade movably mounted thereon, and a movable support beneath the pencil point said support being adapted to form a gage for the insertion of the pencil for the preliminary cutting of the wood thereof.

A further object of the invention is to provide a novel and improved construction of pencil holder having a pivoted lever carrying a shaving blade and a rotatable pencil clasp adapted to be operated in the movement of said lever in one direction to turn the pencil within the holder laterally between the shavin operations of the blade.

Other and furt er objects and advantages of the invention will be hereinafter fully set forth and the novel features thereof defined by the appended claims.

In the drawing :-Figure 1 is an elevation of the invention; Fig. 2 is a detail vertical section; Fig. 3 is a side elevation of the sharpener; Fig. 1 is-a vertical section thereof showing the sharpened pencil in position; Fig. 5 is a detail plan of the blank from which the point support is formed; Fig. 6 is a similar view of the blank from which the pencil holder is formed, and Fig. 7 is a detail perspective of the cutting blade.

The pencil holder 10 is formed in any desired manner or configuration, preferably being formed from a blank of sheet metal, as

shown in Fig. 6, bent into tubular form and the meeting edges 11 thereof secured together. These edges are provided with extensions 12 which form pivoting lugs for the lever 13 carrying the cutting blade 1 1. The blank is also provided with a tapering aperture 15 over which the lever 13 oscillates, and the side edges 16 of this aperture are adapted to contact with the blade 14 as hereinafter described. The holder 10 is also provided with a finger hold 17 at one side and secured thereto in any desired manner, for instance, by the apertures 18 to receive the lugs 19 of the finger hold 17 The outer end of the holder 10 forms an inclosing casing 20 one end of which is bent or crimped inward, as shown at 21 to form an abutment for the tension spring 22 disposed within the casing. Slidingly mounted in this casing is the point support 23, which may be formed in any desired manner, and is provided upon its upper face with a depressed port-ion 24 adapted to receive the point of the pencil, as shown in Fig. 1. A preferable form of constructing this support comprises the blank, as shown in Fig. 5, the opposite ends 25 of which are curved and bent at an angle to the body to conform to the interior of the holder in which it reciprocates. For the purpose of operating this support by hand, a lug 26 is extended from one side thereof between the side walls 11 of the holder which at that point are spaced apart, as shown at 27 in Fig. 3. The support 23 is normally held in the position shown in Fig. 4 during the sharpening of an already pointed pencil, but when a new or uppointed pencil is inserted, this support is forced into its inclosing casing, as shown in Fig. 2, thereby forming a gage determining the extent to which the pencil shall be inserted.

The sharpening lever 13 is pivotally mounted upon the lugs 12 by means of the bolt or pivot 28 extending therethrough, and for the purpose of permitting a yielding movement of this lever during its return travel, a spring washer 29 surrounds the shank of the bolt 28 and is secured in position by means of a nut 30, as shown in Fig. 3. The lever is provided with flanges 31 to receive the opposite ends of the blade 141: which is secured in position by means of the screw 32 or other fastening device. This blade may be of any desired character, but is preferably formed with each of its longitudinal edges 33 inclined in opposite d1rec-- tions so that it may be reversed in position to secure new cutting edges, and these edges retained in sharpened condition by their contact with the pencil lead and the side walls 16 of the aperture in the holder. The lever is provided with a handle portion 34 having the aperture 35 therethrough so that the thumb and finger of the user may be brought into contact through the aperture and a firm hold thus secured.

For the purpose of imparting an intermittent rotary movement to the pencll between the shaving actions of the blade thereon a clasp 36 is provided and is rotatably mounted upon the holder by means of thecrimped edge 37 thereof which enters a circumferential recess in the clasp, as shown in Fig. 4. This clasp may be of any preferred construction for retaining the pencil therein, such, for instance, as the series of separated spring portions 38 which engage and retain the pencil within the clasp by their tension thereon. This clasp is also provided with a series of ratchet teeth 39 upon its end next the cutting lever and these teeth are adapted to cooperate with a pawl or projection 40 carried by the under side of the lever, as shown in Fig. 1.

In the operation of the invention, the pencil to be sharpened is inserted in the holder in the position shown in Fig. 2 at which time the pencil support is forced inward to form a gage to determine the extent of insertion of the pencil- The lever and cutting blade are then oscillated toward and from the end of the holder, as shown by dotted lines in Fig. 1. For partially rotating the pencil upon the return movement of this lever the pawl engages the ratchet upon the pencil clasp and imparts a partial rotation to the pencil so as to present a new surface. In order that this return movement may be effected without tension upon the pivot of the lever or binding in contact with an angular surface upon the pencil the spring washer is provided and permits a yielding of the lever upon its pivot during the return movement. As the sharpening action progresses and the wood of the pencil is sufficiently removed, the spring forces the point support beneath the point of the pencil, as shown in Fig. 4 thus absolutely preventing breaking of the lead and permitting a completion of the sharpening action with the under side of the pencil point supported.

The finger hold upon the holder permits the tain the holder and pencil in proper relation user to secure a firm grasp which will reto each other during the sharpening of the wood of the pencil which is also automatically rotated in the alternate movement of the lever during the sharpening action. It will be seen that the invention is adapted to be formed from sheet material properly stamped and shaped so as to provide a simple, economically constructed and very efficient pencil sharpener in which the blade may be reversed and retained in sharpened condition. During the cutting action of the blade the beveled edge thereof contacts with the lead of the pencil, while during the return movement this blade is brought into contact with the edges '16 of the aperture in the holder. When it is desired to further sharpen a pencil already pointed the point support may be withdrawn by means of its operating lug to indicate the extent to which the pencil shall be inserted in the holder. The support is then released and thrown by the spring beneath the point of the pencil so the pencil to be sharpened to provide a support therefor.
