@glatt-uit Qy, (ittica Letters Patent No. 83,767, dated November 3, 1868.
MROVEMENT IN MOWER LND REAPER-KNIFE SHARPENERS.
The Schedule referred to rin theme Lettera Patent and making part of the same.
To all 'whom fit may concern.
Be 'it known that I, WILLIAM B. DEUEL,of Ithaca, Tompkins co'nnty, New York, have invented an Improved Mower and Reaper-Knife Sharpener; ,and IA do hereby declare that the followingr is a full and ac-` at the proper angle or inclination, the knives of a mower or reaper upon the plain ordinary face vof a common and any-sized grindstone. v y v This I accomplish by making a wooden or metallic side piece or plate, which I attach, usually, onveach side of the frame of a common stone. To this side piece or plate, by the series of holes in the same, I adapt an arm or projecting piece, which has dowels, pins, or hooks fitting into any two or more of the holes in the side plates, and thus I make an approximation to fitting the knives to the stone.
On this arm or projecting piece I fasten, by setscrews, the holder for the cutter-bar and knives, making the closer approximation of thebevel bf the knives by turning the holder on a bolt or joint, aided by a straight orv curved slot`iu the arm.
l' When one side of the knives is ground, I raise the dowel-pins or hooks out of the Aholes or mortises in the side plates, and pnt them in the corresponding holes of the same or oppositeside of the stone, and thus' I grind and sharpen each side ofthe knives as I move them on in the hollow of the holder. l
I make the holder with a V-shaped or rounded deep cavity, to it the varying thickness of varied cuttei'-, bars, and by clamps and set-screws hold the cutterbar by-its upper edge, yand thus dt any thickness and Width of cutter-bars.
These parts are seen iu the drawings, where, in g. l, A A is the frame of au ordinary grindstone; B, the stone; C, the plate attached to the frame; and D, the holes in the same, for receiving the hooks or pins, E, of the side piece F, which has th'e bolt G through any convenient-shaped slot in it, with the set-screw H holding the bolt in its place in the slot, and having the holder I on the upper end of the bolt, held bya set-A screw. The clamps L andL hold the cutter-bar M by its edge in the hollow of the holder.
It will be readily seen that the dowels, pins, tenons, or hooks E are adjustable to any two of the holes D and D in the side piece or plate C, thus making the approximate fitting to the stone, be it of any size, and at either end of the stonefrarne. And by the set-screw H, the holder can be set at any place in the slot,.in the arm or side piece F, thus moving the knives to or from the stone. And by the upper set-screw ofthe boltvG, above the arm or side piece F, the'holder I can beset at any angle to thestone. And by allof these parts the knives are ground on the common plain face of a common grindstone, be its 'size and thickness what they may. And by a plate, G, on each side of the frame A, each side of a thick stone can be used, and the stone wear evenly, and in the ordinary way, or by bevelled surfaces.
In iig. 2 the same letters indicate the saine parts, and, by what has been said, its parts are easily nndeistood.
In iig. 3 is seen a section of the cutter-bar, knives, and the knob for the clamp, and clamp attached. In it, I is the section of the deeply-grooved holder, with a hollowed V-shaped bottom, and M is the cutter-bar in it, with the knives attached to it, held by L, the clamp on its edge, and I is the clamp-knob, with vset-screw at its base. 1 v
In iig. 4, G is the bolt through the slot FY', in the arm F, held in place by the immovable collar O and the set-screw H, andvI is the projection from rthe holder I, binding the holder fast at any angle to the stone, by the setscrew J, and having either one plain loose collar, N, or two angled or oblique collars, N, between the holder I and xed collar O ofthe bolt G.
, The use of the double Vand inclined collars N is to set the holder I at any lesser Obliquity or angle to the stone, and thus iit the bevel of the knives more per'- iectlyto the stone.
The uses and advantages of my invention are clear and apparent to those skilled in the art to which it appertains.
C latins.
1. The arrangement and applicatipn, to the sides of an ordinary grindstone, of the'plate or plates O, made with holes or mortises, to receive the pins or hooks E,
lI?, with the pins or hooks E tted to two or more of the holes in the'plate C, and adjustable anywhere in the series of holes in the same, and sustaining the bolt Gr in its slot in the arm, and the cutter-bar holder, as set forth. y
3. The cutter-bar holder I, when fnade with the deep Vand hello-wed V-shaped bottom cavity, substanf tially as set forth. l
4.' The bolt G, when held in place in the arm -Fby the set-screw H, and adjustable for the holder I by the set-screw J, and the collar or collars N, bevel or ob liqnely, as described.
The clamps L, so arrangedas tovhold the cutter- A bar M in the cavity of the holder I, by the edges of the cutter-bar, and on the rear oi' the knives, thereby leaving the faceof/` the' kniyes free, and open to the stone, as described.
6. The combination of the plates C, arm F, bolt G, and holder I with the frame of an ordinary grindstone, constructedand arranged to operate as setforth.v
