ToalZ whom it may concern.- 5 1 Be' it known that 'I, ADELBERT R. CLIZBE, a citizen of the United States, and a resident .of Plymouth, in the county of Marshall and 5 .State of Indiana, have invented certain new and. useful Improvements in Grinding-Ma} chines,of which! do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forminga part of this specification.

The object of the present invention is to provide an improved constru'ction'of grinding machine which, while capable of use for a variety of other purposes, is more especially der5 signed for the grinding of barrow-disks, re-

- ,volving plow-colters, and the like.

The invention consists of the various novel features of construction hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the claims at the end of this specification. .Figure 1 isa plan view of my improved eonstruetiomshowing the parts in position for grinding a dished -harrow-disk.- Fig.2 is a view in sectional elevation of the same on line 2 2 of Fig, 7. Fig. 3 is a detail sectional view on the line 3 3 of Fig. 1. Fig. 4 is a view in side elevation of a part of the structure shown'iuFig. Fig. dis a detail sectional 3o yiew online 5 5 of Fig. 1. "Fig. 6 is a detail view of apart of the structure shown in Fig. 3; and 'Fig. 7 is a view similar to Fig. 1, showing thepart in position for griudinga flat disk.

The frame of the machine consistsof a bedplate A, provided at either end with castings B B, secured thereto by bolts 0 C, and to which are suitably fastened the supportinglegs D D Mounted on a circular plate or casting E is a gear-support F, both of which are secured to the bed-plate by bolt 0. 'lhesupportF consists of side pieces 10 ana11, eurvea end pieces 12 and 13, and central plate 14, all preferably cast integrally. The plate 14 is provided with a downwardly-projccting circular rib 15', which fits within a corresponding depression 1'6 in the plate E. By loosening the nu on bolt C the support 1" may beadjustcd rotatably to any desired angular position.

are the drive-shaft 17, carrying the gear 18 Mounted in suitable bearings in support F and operating-handle '19, the counter shaft" 20, carrying pinion 21 and gear 22, and the grinding-wheel shaft 23, carrying the grind-, ing-wheel G and pinion 24. The pinion 21 ,55 gears with the gear-l8 and the-pinion 24 with, the gear 22, so that by means of the handle 19 the grinding-wheel G may be driven at a high speed. The outer flat face of the wheel G is employed as a grinding-face, and in order to provide for wear this face is provided with a recess 9 (see Fig. 5) for the nut g, by which the wheel is secured to the shaft 23. The support F and wheel G are set atan augle to the length of the bed-plate A, so that the grinding-face of the wheel will accurately engage with the bevel of the disks to be ground. The extent of this angle, as before stated, is adjustable to provide for grinding disks of varying sizes. In order that the '70 wheel G may accommodate itself to'disks hav ing irregular edges, either because they have been sharpened in the usualway by a blacksmith or because they have been bent in any way, the shaft 23 is loosely mounted. in the bearings and permits of a certainamount of longitudinal movement, limited by thepinion 23 and the collar 25 on either side of one of the bearings. A light cushion-spring 26 is placed about the shaft 23 between the collar 25 and one of the sides of support F, which tends to push thewhecl G outwardly against .the disks to be ground.

The end of the base-plate A opposite'the gear-support is provided with a longitudinal slot (1, above which is mounted the circular disk holder support II. ,Bolts 27, having winged nuts 28, pass through the slot 0, in the base-plate A and through arc-shaped slots Jt in the disk-holder support II, by means of which the support may belongitudinally adj usted to and from the gear-support F and wheel G to providefor disks of varying sizes and rotatably adj ustcd about a vertical axis, so that the disk shall be presented at the 5 proper angle to the grinding-wheel G.

Loosely mounted in suitable hearings in they support II is the disk-holder I, so as to be rev; oluble and longitudinally movable therein: The holder I is provided at one end with the fixed flange 29 and the flanged hand-nut 29, by means of which tl i disk Kisheld in place.

IOO

5 vided with a grooved collar 31,"which is surthe circular support 11 andprovided with prolike, the combination with a frame, of a grindrounded by the bent forks 32 of handle 33. These forks are pivoted toprojections 34: of

jections 35, engaging the grooved collar 31.

IO By this means the disk-holder may be moved 4 longitudinally by hand to suitably press the disk to the gro g instthe grindingsface of the spri'ngFpressedwh a Mounted npon'd rive-shaft 17 is a bevel-gear" r5- 36, engaging a second bevel-gear 37 on ashort part 13 of support F. This shaft 38 is con-- I shaft-38, angularly mounted on ajbeariug in uc cted by anniversal joint 39 to the inclined rounter-shait 40, which passes through bear- 2o ings in the castingor gearsupport 41-,mounted on lhoshaltofthe revoluble disk-holder I Between bearings for the counter-shaft 40 in the casting orgear support 41" and keyed to the shaft 40 is the worm-gear 42,110 as tube;

longitudinally movable upon but revoluble .l holder 1-, and one of the bearings thereof is with-said'shaf t. The worm-wheel 42 engages the gear 43, 'keyed to the shaft of the diskholder, whereby the latter" is revolved;'-v but said shaft is longitudinally movable through said gear 43. It will be seen that the flexible universal connection betwcen'th'e drive-shaft and the shaft of the disk-holder permits the longitudinal adjustment 'of the frame H in order to accommodate disks'ofvarying sizes. In order to permit the angular adjustment of a the supports F and H to properly present the disks to. the grinding-wheel, the casting 41 is looselymounted on the shaft of-the diskiu ihe. form of a longitudinal slot 4*, (see Fig.- 6,).so that the support '11 may be angularly adjusted relatively tothe shaft 40 and to support F. r I

I It, is obvious from the foregoing that disks of. varying sizes and shapes'may be secured to the disk-holder and the parts adjusted and operated to suitably sharpen the edges of such disks. In Fig. 1 I have shown the parts adjusted to grind .adished disk K, such as as are used in stalk-cutters, &o.

are .used in disk harrows, eultivators, and the like.- In'Fig. 7 I have'shown' the parts adjusted to grind alarger plate-disk K, such The parts are preferably adjusted so as to bring the edge of the disk to begronnd opposite the center of the wheel G5 a In the operation of the device the handles 19 and 18 are so arranged that the parts may be operated with the right hand and the disk pressed against the grinding-wheel with the left. In the operation of the grinding-machine ,the wheel G will be revolved at a high speed to rapidly grind the edge of the disk, and the disk itself will. be slowly-and uniformly revolved to present its entire circumference to the grinding-wheel.

' It is obvious that the-parts of the structure '3." In a gri may be varied by the skill of the mechanic without departure from the essentials of the invention and that feature of ,thesame may be employed without its adoption in its en tirety. T Whatl claim-as new, and desire to secure by Letters Patent, is- 4 1.
