PENCIL-SHARPENER.

` Specification of Letters Patent.

Application filed October 25; 1911. Serial N o. 656,577.

To all whom it may concern:

Beit known that 1, FREDERICK A. FRICKER, a citizen of the United States, residing at Scranton, in the county o f Lackawanna and State of Pennsylvania, have invented new and useful Improvements inv Pencil-Sharpeners, of which the following is a specification.

The invent-ion relates to Sharpeners and more kparticularly to the class of pencil sharpeners.

r1he primary object of the invention is the provision of a device of this character in which pencils may be readily and quickly sharpenedwithout. requiring the use of an ordinary knife or the like.

Another object of the invention is the provision of a Sharpener in which the end of the pencil to'be sharpened is held in a' guard which prevents the possibility of the displacement of the said endor the break.- ing of the point of the lead in the pencil when being sharpened.,k

A further object of the invention is the provision of a sharpener which is simple in construction, thoroughly reliable and etlicient in operation, and inexpensive in manufacture.

With these and other objects in view the invention consists inthe construction, combination and arrangement of parts, as will be hereinafter more fully described in de-l tail, illustrated in the accompanying drawings andpointed out in the claim hereunto appended.

ln the drawings -Figure lis a side elevation of a Sharpener constructed in accordance with the invention, the case being partly broken away; Fig. 2 is a vertical longitudinal sectional View of the same; Fig. 3 is a sectional view on the line 3-3 of Fig. l..

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings by numerals the Sharpener comprises a base. of circularshape which is formed f with a circular shaped boss 10, at the center thereof, the boss being surrounded'by means of a; collar having inner and outer 11p-standing

flanges

25 and 26, providing an annular pocket 27 to receive pencil shavings. A cylindrical casing 6 is provided, the lower end'thereof being fitted in the pocket 27 for engagement with the iiange 26, being closed at' its upper end by a rotatable disk forming a top*7 which the base 5 at the'center thereof, the boss at its upper face 'being provided with periph.-

eral gear teeth 11 meshing with a beveled pinion 12 fixed to a shaft or stud axle 13 having one end journaled in a bearing 14 formed on the stem 8 and projecting from one side thereof, while the opposite end of this shaft or stud axle 13 is journaled in a bracket 15 integral with and depending from the rotatable top 7, it being seen that on the rotation of the latter' the pinion .l2 will be driven vthrough the medium of the stationary gear teeth 11 formed on and rising from the boss 10 upon the base 5 of the device for apurpose presently described.

Integral with the top 7 on the casing 6 and project-ing above and below t-he same is a pencil guard comprising a tapering sleeve 16 provided with a pencil receiving socket 17, the lower end portion of the sleeve being cut-away to provide a gap 18 at one side thereof so as to project the end of a pencil inserted within the socket 17 into the path of movement of a cutting element, presently described.

Fixed to the shaft and stud axle 13 is the cutting element comprising a disk or wheel 19, the side thereof facing the gap 18 in the guard or sleeve 16 being provided with beveled sharpened cutting teeth 20 which are adapted to cut away the wood of the pencil and the lead therein for the sharpening thereof lwhen inserted within the guard during vthe rotation of the top 7, it being understood, of course, that the pencil is gripped by the hand of an operator and is caused to turn in the socket 17 thereby intermittently presenting to the cutting element an un-sharpene'd or un-cut surface whereby on the continued rotation of the top 7 the end of the pencil will be completely sharpened to present a pointl thereto.

1t will be noted that the guard will prevent any possible displacement of the end of the pencil when being sharpened by the cutting element and also the said end will be protected by the guard so as to obviate Patented sept. 1o, I1912. l

the breaking of the sharpened end during i the sharpening operation of the device.

The sleeve 16 at its upper end is split at 21 so as to provide yielding portions 242,v

the outer surfaces of whichare provided with screw-threads 23 engaged by a binding collar 24 which causes the slight contracting of the split end of the sleeve so that a pencil will fit closely within the socket 17 therein yet freely turn in the socket during the rotation of the top 7 for the sharpening of the pencil end. It is evident that by adjusting the collar 24 upon the split end of the sleeve, the same may be adjusted to accommodate different sized pencils and avoid the wabbling or displacementof the pencil as -well as hold it in perpendicular position.

From the foregoing it is thought that the construction and operation of the invention will be apparent, and therefore,- a more extended explanation has been omitted.

What is claimed is:

A pencil Sharpener comprising a base having a centrally located boss rising therefrom, a collar having inner and outer upturned flanges to provide an annular pocket, said collar surrounding the boss, a cylindrical casing, the lower end of the same being fitted in the said annular pocket, a standard rising from the said boss, a cog gear fixed to the boss concentrically with respect/to saidy standard, a rotatable disk having a depending hollow stem surrounding the standard, bearingsy on the casing and the said stem, a stub axle in said bearings, a beveled gear fixed to ,said stub axle and meshin with the cog gear, a cutting element fixed `to said stub axle, and a pencil receiving means intersecting the top of the casin speci ed.

In testimony whereof I aix my signature in presence of two witnesses.
