' improved machine of this character in which the cutter serves as a means for rotating and feeding the pencil to its proper position to be cut.

To this end and the accomplishment of other new and useful objects, as will appear, the invention consists in certain features of novelty in the construction, combination, and arrangement of parts hereinafter set forth and claimed, and shown in the accompanying drawings, illustrating an example of my invention, in which- Figure 1 is an end elevation of my improved machine. Fig. 2 is a longitudinal section on line 2 2 of Fig. 1. Fig.,3 is anenlar ed detail section of the end of the pencilsoc et, showing the end of a pencil in position to be sharpened. Fig. 4 is a transverse section on line 4 4 of Fig. 1. Fig. 5 is a section on line 5 5 of Fig. 1. Fig. 6 is an enlarged detail section on line 6 6 of Fig. 1, and, Fig. 7 is a detail perspective view of the point rest or support.

Referring to the drawings, the numeral 1 designates the body of the machine, which may be of any desired shape and material, but is preferably formed of metal cast into the desired shape and is provided with a socket or cavity 2, which is adapted toreceive the end of a pencil., Said socket extends from the periphery of the body in an inclined position to and through the side of the body, thus forming a slot 3. The socket is provided with a reduced. portion near its lower end to form an inclined wall or portion 4, and the extremity ofthe socket is tapered or con-l ical, as at 5. W`ith this construction of socket the slot 3, formed in the side of the body, will be in the shape of a keyhole-slot,

as shown, the particular advantage for which Y' will be set forth. l

The numeral 6 desi nates a ferrule or sleeve7 which is provide with a plurality of slots 7. A plurality of springs 8 are secured, preferably at their, upper ends, to the sleeve or ferrule by means of bolts or screws 9, and

said springs are curved around the outside of the sleeve or ferrule. -The ends thereof are bent at a substantially right angle to the body portion7 as at 10, and said bent portion is adapted to extend through the slots and into the ferrule or sleeve 6, the extremities of the bent portions being formed into an extended knife-edge 11 for the purpose of gripping a pencil to permit a longitudinal dmovement thereof through the ferrule or sleeve and to force it to rotate with the sleeve or ferrule when the latter is rotated. Said sleeve or ferrule is also provided With a plurality of radially-projecting and spaced iingers 12, located, preferably, intermediate the base of the slots 7 and the end 13 thereof. The upper portion of thel socket 2 is slightly enlarged, as at 14, and is adapted to loosely receive the lower end '13 of the sleeve or ferrule 6.y This enlarged portion is of such a depth that when the extremity 13 of the sleeve or ferrule 6 is mounted therein the radially-projecting fingers 12.Will rest u on the top of the body portion 1- and project eyond the side thereon in which is provided the slot 3.

`In order to prevent accidental displacement of the sleeve or ferrule 6, I provide the same with a circumferential groove 14a, which is adapted to register with a notch 15 in the body, and into the registering groove and notch I insert apin 16, which will permit said sleeve or collar to rotate,. but will hold it against displacement.

Mounted within the body 1 and transversely thereof is an axle or shaft 17, to one end of which l secure a crank 18 in any desired manner, and 19 designates a bushing in lwhich the axle rotates. The free end of the Shaft or axle .17 adjacent the face of the body 1, which is provided Withthe slot 3, is preferably enlarged, as at 20, and 21 is a recess in the body 1, within which said enlarged portion is adapted to stan/d, so that the outer face thereof is flush with the face of the body. A cutter 22 is secured to the end of the shaft 17by means of the screw 23 passing therethrough and into a threaded seat in the end of the shaft 17, and 24 represents a plurality of pins passing through the cutter and intothe end of the shaft to hold the cutter "firmly to the shaft to cause the same to rotate therewith. .The cutter rests against the fache of the body 1 and is provided with any desired number of blades or arms, each of which iS pro vided withacutting edge 25. The extrem- ITO tlm

ity oi each arm vis bent, as at 26, slightly out of the plane ol the body portion, and said arms are of such a length that the bent portion 26 thereof will engage the radial projecting fingers 172 when the crank i8 rotates the Shaft 17.

Removably seated in a transverse aperture 27 in the body l and at the base of the socket 2 is a pin or support 28, which has a portion thereof cut away, as at 29, to Jform a shoulder therein and upon which the lead of the pencil will rest. This rest or support is adapted to be rotated so that the point of the pencil will rest upon the cutaway portion or the periphery thereof, according to the size of the point desired. 'i I The ferrule or sleeve 6 is of such a size as to receive an ordinary or extra large pencil, and in order to accommodate the Sharpener to a smaller pencil and to hold. and guide the same when in position Yl provide a springsupport 30, which is secured, as at 31, to the body l. 'he upper end thereof is bent over the end. ot the sleeve or ferrule 6, with the grooved end 32 normally standing approXimately' o ver the diametric center ofthe opening in the sleeve or'lerrule 6. Said spring 30 is preferably provided Iwith a bifurcated portion or arms 33, adapted to stand astride of the sleeve or iicrrule 6 and rest upon the u per lace of the lingers or projections l2, vr ich will in holding said ierrule in position also permit of the easy movement of said spring.

fl. box or drawer Se is mounted in the base of the machine to catch. the shavings, and 35 represents guides to direct them into the box or drawer through the opening 36. c

The operation of my machine is as follows: The support or rest 28 is first laced into the desired position according to t e size of point desired, which may be'done by pushingv said support out of the aperture 27 from the face of the machine adjacent the cutter` pencil is then inserted until its end rests upon-the seat formed by the reduced portion or' the errule or sleeve and so that a portion of the pencil will extend through the enlarged portion of the slot and into the path of the movement of the cutting edges of the cuttenarms, as shown in Fig.v 3. T he knife-edges llof the springs 8 will grip the pencil and cause 'the same to be held in position. ,The shalt 17 is then rotated, causing one ot' the blades to cut oli the projecting portion of the pencil, the pencil being prevented from longitudinal movement by means of the reduced diameter oi the sleeve or terrule. Upon the completion of this cutting movement the bent end 26 of the next arm will engage one of the projecting fingers l2 and rotate the sleeve 6 and the pencil therein, thus bringing a new portion oi the pencil through the slot t'o be cut'. This operation will continue until the last portion of the pencil which projects seance through the upper part of the slot has been cut. Thecompletion 'of this last cut will serve to drawthe pencil through the springs 8 and down the inclined portion 4 of the socket, causing more of the pencil to protrude through the upper or enlarged portion of the slot, while 'the already cut portion will enter the conical portion 5 and extend through the smaller portion of the slot lower down. When the pencil has been cut, as before, the cutter making the last cut will draw the pencil still farther'into the socket until the lead or point thereof rests upon the support 28 and the crank rotated until the blades cease cutting or until all of the protruding portion of the pencil has been cut ofi, at vi hich time the pencil will have been completely sharpened. The pencil can then bewithdrawn from the sleeve or ierrule 6, the springs 8 permitting its easy removal.

rlhe springs 8 are of such a strength to firmly hold the pencil and cause the same to rotate with the sleeve or ferrule 6, yet they permit of an easy adjustment Without materially scratching or cutting the same.

Having thus fully described my invention, l desire it understood that I do not Wish to be limited to the exact size, construction, and arrangement of the several parts, as numerous changes may be made Without departing from the spirit of my invention.

Having thus described my invention, what l claim as new therein, and desire to secure by Letters Patent, is-
