SPECIFICATION forming part of Letters PatentNo. 481,018, dated AfhfgtlstA 16, 1892.

Application iiled May 10, 1892. Serial No. 432.409. (No model.) I

T @ZZ whom it may concer/t:

13e it known that I, FRANK E. hnnee, of N ew VYork city, in the county and State of New York, have invented a new. and Improved Pencil-Pointer, of which the following is a full, clear, and exact description.

My invention relates to an improvement in pencil-pointers, and has for its object to provide a machine capable of rapidly and perfectly pointinga pencil of any description and of producing a point thereon as long as may be desired.

Another object of the invention is to construct a machine capable of pointing pencils expeditiously, and also capable of being conveniently manipulated.

A further object of the invention is to construct the machine in an exceedingly simple and economic manner. y

The invention consists in the novel construction and combination ofthe several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanyingr drawings, forming a part of this speciiication, in which similar figures and letters ot' reference indicate corresponding parts in all the views.

Figure lis afrontelevationol' the machine. Fig. 2 is a partial vertical section through the body of the machine, the grinding-disk and drive-wheel being in edge view. Fig. f3 is a vertical section through the pencil-clamp and a front elevation' ot' the body of the machine, theV driving-wheel and grinding-disk being removed. Fig. 1 is a side elevation of the grinding-disk. Fig. 5 is an enlarged vertical section through the pencil-holder, and Fig. U

's' a section taken practically on the line C f5 Iii lg. 3.

The body or casing A of the machine is mounted upon a base .I3 of any approvedeonstruction, and the body or casing consists o l a face-plate 10, the upper portion of which is more or less cylindrical, the lower portion heing somewhat tapering or wedge-shaped, and a marginal flange 1i,cxtcnding around the top and side portions ol' the plate to an engagement with the base. In the upper ccntral portion of the Ilange ll of the body an `is best shown in Fig. 3.

opening 12 is made, and adjacent to that opening upon the outer face of the flange a pinion 13 is pivoted. Upon the inner face of the plate of the body, immediately below the opening 12 therein, a socket-plate 14 is located, being rigidly secured to the body, as This socket-plate provided with a conical vertical bore 15, eX- tending from top to bottom, the bore being visible from the front ofthe socket-plate, as that portion of it is conically eut from top to bottom, as shown in Figsf and 6. IThe taper of the bore 15 corresponds to the taper of a properly-sharpened pencil, and the outer face of the socket-plate is beveled from the top downward, the upper line being indicated at a, in Fig. 6, and the lower line at a,'

and in the front or outerface of this socketplate a series of transverse grooves or channels 16 is produced, adapted as conduits for the dust created by the sharpening of the pencil. l

In addition to the casing a drive-wheel 17 is employed. attached crank 18, whereby it is rotated. rlhe inner face of the Wheel is provided with teeth 1), beveled so as to mesh with the pinion 13, and the spokes 20v of the wheel are carried inward and are made integral with a disk 21, the in ner face of which disk is beveled from its center in direction of its periphery,- as shown in Fig. i2, and upon the beveled surface of the disk a correspondinglyshaped strip 2 ot sandpaper, einery, or other material of an abrading character is adapted to be secured by glue, cement, or otherwise, the attachment between the grinding material and the disk being so made that one may be removed from the other when the grinding material has become damaged, so that othermaterial may be substituted for that worn out. 'lhe bevel of the inner face of the disk 21 and the bevel of the outer-face of the socket-plate 11 is the same, as is also shown. in Fig. 2, as

This wheel is provided with an the surface of the disk carrying the grinding IOO Y of this cup is iade somewhat concaved, inv

sists of a tube 26, having 'a threaded upper end and provided with a head 27, the lower end o f the tube being made tapering or split', forminga chuck-section 28. The thread upon thetube 26 is exteriorly produced and is pref-` erably a left-hand thread, as it is adapted to receive a socket29, the upper portion of which socket is threaded to receive the thread upon the tube, while the lower portion of it is reduced in such manner that when 'the sleeve or socket is screwed upon the tube the jaws of the chuck-section of the tube are'forced.

inward to clamp any articleY placed between them, the pencil 30 to be sharpened being passed down through the tube and out between the jaws at the lower end of the tube. The sleeve 29of the clamp has a beveled pinion 31, produced upon its outer face, and this beveled pinion is adapted to mesh with the pinion 13 upon the body when the lower end of tliesleeve has been entered into the opening 12 at the top of the body, as shown in Fig. 3.,

In order that the dust from the pencil as it is being sharpened maybe prevented from dropping uponthesupport a cup 32 `is located within the lower portion of the body A, be

ing attached in any suitable' mannereitherv to the base orto the body. The upper face order that itmay lit snugly in the bodyand yet admit of the revolution of the drivewheel17. In theioperation of the-pencil pointer or 'Sharpener the pencilis placed in the vclamp beingI passed downward through the tubesection 26 of the clamp, an'd the end to be sharpened is made to extend a predeterinin'ed distance beyond the chuck end ofthe tube; as shqwn in Fig. 3.. Before this is done the sleeve 29is partially unscrewed from the tube-scction'of tim clamp, so as to admit of the-jawsof the latter being opened; but after the pencil has been placed in position the sleeve-isscrewed upward upon the tube-section, closing the `)aws of the chuck portion ofthe -tube around the pencil. The lower end of the sleeve-of theclamp is now passed into the opening 12 at the top of the casing, and the gear` l31 upon fthe-sleevewill engage '.-with the bevel-gear 13 of the body, and by exerting downward pressure upon the head 2"? of the clamp and turning the handle 18,

attached to the drive-wheel 17, the latter will revolve-the clamp through the medium of' the'pinion 13, and will also turn the disk carrying the abrading material, and this material, being brought in yconstant engagement while revolving with that portion of the wood and lead'of the pencil exposed through the vertical cut in the socket-plate, will sharpen the pencil, give it the proper shape, and taper the wood above the point, and this Ais especially so as the pencil while being subjected 4to the action of. the abrading material isalso revol 'edf This device is simple, durable, and economic, and is capable of being operated succes'sfully by any person. As the material `is, rubbed from the pencil during the process of sharpening, it passes-olf through the channels A16 in the' socket-plate 'and drops downward into the cup 32. l.

Having thus described my invention, I claim as new and desire'to secure by Letters Patent- I 1.
