IMPROVEMENT IN MACHINE PoR .eRINDINe THR oUTTRRs- 0I'I IIIOWINc-MAGIIINBS. A

To' ALL wHoMIT MAY coNoERN:

Be it known that we, HENRY F. PHILLIPS and HENRY `LEONARDofvAuburn, in the county 'ol'Caynga, and State of New York, haveinventcdcertain new and useful Improvements in Macliinesfor Grinding Mowin'g and Reaping-Machine Sections; and we do hereby declare the following to be afullclear, and exact description of the sama-reference being had to the accompanying drawings, making a part of this specification, in which-j- Figure 1 represents an 'end elevation ot" the machine.

Figure 2 represents a side view of thc same.

`Figure 3 represents a top plan, and' i y Figure 4 represents a vertical section, taken at the red line w of iig. 2.

Similar letters of reference, where they occur `in the'separate figures, denote like parts of the machine in all of the drawings. I

Our invention relates topa machine for grinding harvesting-'machine sections,` whereinthestone is fedup to the sections whilst the latter' is rigidly held, or in feeding up the sections whilst the stone is rigidly held; and it further relates to a rocking or rolling motion given to the frame, for adjusting thedp or inclination of' the stone, as well as its sliding motion, to tix the position of thestoneyand it further relatesto th'e arrangement Afor holding-and controlling the knives`or sickles and their bar whilst being ground. i

` To enable others skilled inthe art to inake and use our invention, we will proceed to describe the same with reference to the drawings.

On a bed, A, is arrangedda block, B, so that it may be movedgnided, and held on said bed, it being moved -betwcen guides a a, and firmly held, when properly adjusted, by the screw-bolt b. On top of the block B, and in a rounded bed or bearing prepared thereon,is placed the yoke-0r bracket C, for forming'bearings c c for the shaft D of the grindstone E to turn-in. Thisbracket orbearer C is held to the block B by the screw-bolt 6, which passes through a slot, d, in the bracket, so that the bracket rnaybe inclined to give an inclination. or pitch to the grindstone, when necessary to do so,v and when adjusted, it is firmly held by the lscrewfholt b. On tho shaft D there is a collar, e, which, when adjusted, is held to the shaftby a set or clamp-screw, f,'and in ,the rear hearcrc there is a mortise, through which an arm, g, moves, the forward end ot'said arm being forked and straddling Ythe collar e in groove, k, therein.. There is also o n the .arm g a mortisc, opening, or shoulder, c', in pr against which, and against the rear bearer e', a wedge, 1c, (shown in dotted lines in fig. 3,)'is slipped, to force, and at the Vsaine time rigidly hold, the grinds'tone against the sections. This feeding up and holding ofthe stone 'against the sections, or cz'ce versa, prevents any vibrations which tend to wear the, stone out of round, or from causing it to jump, when a -hard spot inthe stone strikes the metal. On top of the rearbearer cf (and there, hy preference, simply for convcnience,) there is a'. set-screw7'.` -which can he run down against the arm g, so as -tohold said arm from moving, and in thus holding said armv the stone'or itsshafL-having no end motion allowed to it, will revolve in a fixed position. This arrangen'icnt is necessary when the grindstone is used (which it canhe) for any o f the ordinary purposes of grinding. i

`In front of the grindstone, and upon the'hed A, there 'is a hollow hub or column, F, in which a spindle, l, onthe holder G, tits and mayturn, and in this hub or socket F there is a' ring-clamp, through which the spindle passes, and by which it'may be restrained in turning by a nut,-m, run up on thc` thrcaded portion n of said ring-clamp. A p

Upon the top of the hub or column F,'and underneath the beareror holder` G, there isa plate, H, the outer ends of which, I I', are formed into arcs, making a support or tablefor the holder -to rest upon. Onon'e of the arcs, I, there is an upright arm, o, adjustable thereon by a. set-screw, p, which passes-through a slot in the ae or table I, so as to be set up more towards or from the stone, as the case may be.. I`n -the top ofthisnpright arm dther'e is dect-screw, q, which bears against the back ot' the holder G, and keeps it in its properly-inclined position. In the holder, at or near the rim of the other arc or table, I', there-is a hook-headed bolt, r, which takes under the edge of the arc or' table, and' whilst it allows the holder to turn on its spindle, it prevents it from rising from the'tablc. l l

anios 2 In a recess, s, in the face, of the holder G, the baron which the knife-sections t to be ground. are fastened,

is placed, and clamped by hook-headed clamps, which are drawn up by thumb-nuts u u, on the rear of the holder, and so that the sectionst shall project above the holder, and allow the corner and face of the stone to come clear down into the corners or angles formed bythe sections. The holder G having been gauged to the required Obliquity, or'the stone havingbeen set, inclined, or dipped, by the rocking bearer C, and then clamped, or by bothI of these adjustments in part, the necessary position of holder and stone having been attained, so as to get theIproper-grinding angle and bevel, the cutter-barand cutters are slid along in the recess s, and clamped by the clamps u u, and then brought to the action of lthe stone and ground. l

When the stone is adjusted, and its shaft retained so that it revolves in a permanent' position, that is, without being fed np tothe sections, then, by means of the vset-screw q, the sections may be fed up with a positive unyielding motion 'to the stone, yto prevent jumping, and consequent uneven wearing of theV stone. This is simply reversing the feed-motion, and feeding up thc sections to the stone, instead of the stone to the sections, but in both cases the feedis rigid, 'for one and the same purpose, viz, tocanse the stone' to wear true, and not out of round, as is the case when not rigidly fed up and controlled. y

Having thus fully described our invention, vwhat we claim therein as new, and desire to secure by Letters Patent, s-

1. In combination with the curved or hollowed-outblockB,the rocking and adjustable bearer c, for adjust'.

ing the shaft of theA grindstone, substantially as .and for the purpose set forth. Y

2. We also claim, in combination with the shaft D and its stone E, the collar e and arm g, so that the stone may be fed and heldup to the sections by a'. positive and unyieldng feed, or' be held rigid by said arm, substantially as land for the purpose described. l

3. We also claim` the combinationof the table or arcs I IA with th holder G, for guiding, holding, and gauging the'inclination of said holder, by devices connected therewith, substantially as described.

' We also claim, in combination with a fixed position of rotation of the stone, the screw q, as a feedingscrew, to feed theisec'tion to the stone and rigidly hold it against jar or motion, and thus prevent thestone from Wearing out of vround, substantially-,as described. v f
