ABRADING-MACHINE.
Specification of Letters Patent.
Patented Mar. 28, 19.16.
Application led December 4, 1915. Serial No. 65,099.
is particularly adapted to the'sharpening of pencils.
blades ofV any description, and which in addition kthereto is capable of sharpening Another object of this invention is to provide ak device of this character which will sharpen a pencil in the form of a perfect cone and without the liability of breaking the lead during the sharpening operation. Y Further objects of the invention will'appear as the following description is read in connection with the accompanying drawingswhich form .a part of thisapplication, and in which Figure 1 is a front elevation. Fig. 2 is a vertical section of the same. Fig. 3 is a top plan view.
Referring to the drawings in detail, A designates the standards which comprise a pair of vertically extending members 1, which are arranged in parallel spaced relation and which are preferably formed of metal. Connecting the lower ends of the vertical members is a plate 2 which is provided on one of its sides with laterally extending jaws 3 which Aare arranged in spaced relation. The lowerfjaw is provided with a transverse opening which is adapted to threadably receive a thumb screw 4 the screw extending through the lower jaw and disposed between the lower and upper jaw. The two jaws are adapted to forma bracket so as to receive Aany suitable support, the thumb screw adapted to hold the standard rigidly thereupon. Formed upon the medial portion of each of the vertical members 1 and connecting the same is a plate 5 which is provided with a transversely extending bearing 6. Jo'urnaled within the bearing is a shaft 7, one end of which is provided with .a head 8, while the opposite end is provided with a horizontally extending bore 9. It will be noted that one extremity of the shaft is mounted within the bearing while theremaining portion of the shaft extends laterally from the'standard of y the side opposite to the side upon which the laterally extending jaws arev formed. Rigidly mounted upon the shaft is a beveled gear 10 which is held in spacedy relation to the standard A by means of a collar 11, theY collar being provided with an lannular flange which isadapted to engage the gear and which cooperates with a secondv collar 12 to hold the gearl in proper spaced relation rigid upon theshaft. The bore 9 formed in the outer extremity ofthe shaft is adapted tothreadably receive a screw v13` ywhich is provided with an enlarged head 14,
the underside of the enlarged head adapted to abut the outer edge of the collar 12 whereby it will be yforced into engagement Vwith the gear to hold the latter rigidly upon the shaft. Y
-Formed integrally withy the outer ex` tremities'of the standard and connecting the parallel members is a horizontally Var,- ranged bracket 1'5 provided with a bearing 16 at a point medially of the .two vertically extending members of the standard, said bearing adapted to receive a vertically arranged shaft 17. This shaft 17 extends above and below the bracket 15 and hasV rigidly mounted thereon a pinion 18, said pinion being arranged Vadjacent the under-y side of the bracket, and is adapted to mesh with the large bevel gear 10. VThe upper vextremity ofthe shaft 15 is provided with .a frusto-conical shaped emery wheel 19, the
wheel being heldin spaced relation to the bracket by means of washers 2O,` Vwhile threadably mounted upon the upper extremity of the shaft is an inverted frustoconical supporting memberV 28 which 'en-` f gages the upper facefof the wheel. This member V28 is relatively smaller than fthe l emery wheel so-that a sharpeningY surface is presented between the lower edge of the member and the outer edge of the wheel.
i v.It will be seenvfrom this construction that upon rotation of the beveled gear and by means of va handle 22, rotary motion will be embodied to the pinion'` 18, and the klatter being rigidly mounted' upon the shaft 17 will cause the emery'wheel Vto be rotated above the bracket 15. c 'y' Referring more particularly tothe bracket 15, the same is formed substantially `T- shaped, the head -portion thereof being indicated as at 23, and the stem as at 24. ItV
will be noted that the head portion23 is vof i indicated at 27, the depression being of suchsuch a length as to extend beyond the lower edge of the emery wheel, the said extensions being provided on the upper face :thereof with longitudinally extending grooves 25, each of the grooves beingsubstantially semi circular in cross section. The stem 24 of the bracket is `provided on its upper face with a longitudinally extending depression 26 which is substantially semi-circular in cross section and which has its lower wall inclined upwardly toward the shaft 17 as a length as to extend ,under the emery wheel and terminating at a point adjacent the shaft 17. Y
lVhen it is desired to use this device Jfor the sharpening of -blades of any description, the bla de is placed withinl one of the grooves 25 so as to cause the cutting edge thereof to lie at an angle to the surface of the emery wheel whereby. upon rotation of the wheel through the medium of the pinion and bevel gear as has been described, the abrading surface of `the `wheel will contact with the cutting edge of the blade and thereby cause the latter to be sharpened. It will be noted that lthe ends of the grooves 25 are open so asto permitthe moving of the blade to be sharpened longitudinally so as to present different sections of the cutting edge to the surface ofthe wheel.
In the sharpening of pencils'7 the pencil is placed within the depression 26 as shown in Fig. l of the drawing, the bottom wall ofv the depression. causing the pencil to engage the undersurface of the emery wheel.
By exerting pressure `upon the outeriend of the pencil, the end to be sharpened may be within full control vof the operator, that is, by exerting more downward pressure upon the outer end of the pencil corresponding upward pressure will be transmitted to the opposite end whereby the pencilA will be caused to engage the under surface of the emery wheel at a corresponding pressure.` In order to more effectively v'sharpeny pencils the underface of the emery wheel has a surface of a. coarser grade than that of the. sides thereof. This ymakes a very keen cutting surface for the pencil and causes the and neatly sharpened.
When it is desired to sharpen shears or the .like the same Vare opened to their yfull pencil to vbe quickly.
ycapacity whereupon the outside edge of one of the blades is laid *.iiat against theside wall of the truste-conical supporting member, ,thev wall beingA of such an inclination as ltc cause 'the cutting edge of the blade tolcontact with thetop surface of the emery wheel at'an angle corresponding to that of the side wall of the supporting member.` Having-placedthe bladeY of theshear to the emery wheel `in the above described manner, the large gear is then rotated to: cause the rotation of theelnery wheel, the direction of rotation being from left to right,`
or from the inside of the shears outward thereby causing the blade to `be sharpened-` with the usual beveled edge. Owing to the fact that the emery wheel rotatesfr'om left to right, any possible chance'of 'producing` a wire edge upon the blade is prevented.
From the foregoing taken in connectiony with the accompanyingdrawings, the con.- l
struction and operation of `my devicer'will be apparent to thoselskilled in the art with-` out i furtherY description,` and that minor changes in size, shape, proportion and minor Y details'qoi construction may be.` made with` out departing from :the spirit and scope! of the appended claims;
lVhatI claim is l. An abrading `machine comprising; a-
hollow krectangular standard, a. clamping bracket formed. on the lower end of 2said standard, a transverselyextending bearing.
formed at themedial portion of said standard, a V'shaft journaled in Vsaid bearing,I a beveled gear rigidly` mounted upon :said shaftv and lying'parallel tosaid: standard, a verticallyextending shaftfyjournaled in the upper end of said standardand extend-- ing above and into said. standard, a pinion keyed tothe said verticalshaft and meshingwith the beveled gear, an abrading V wheell rigidly mounted on the upper ex-` tremityl of said verticalshaft, and an article supporting.Y bracket formed on the u pper end ofsaid standard andl disposed in close. proximity to the under surface ofsaid wheel and extendingk beyond the pe-l ripheryA of said wheel.' n
