IMPROVEMENT I'N GRAIN AND GRASS HARVESTERS.

Specilication forming part of Letters Patent No. 13,53, dated July 24, 1855; Reissue No. 882, dated l January 3, 18C0.

DIVISION A.

To all whom it 'may concern:

Be it known that I, JEssE URMY, ot' Wilmington ,in the county ofNew Castle and State ot' Delaware, have invented-certain Improvementsin Grain and Grass Harvesters5 and I do hereby declare that the following is a full, clear, and exact description of the principle or chaiacter which distinguishes it from all other things before known, and of the usual manner of making,modifying, and using the same, reff -erence beinghad to the `accompanying drawings, of which- Figure l represents a plan of my reaper and mower; Fig. 2, a side view showing the'gearing, Sie.; Fig. 3, a 4sideview of my partingboard; Fig. 4, a front view of the dogs b b; Fig. 5, the gearing, and shows the mode of adjustment; Fig. 6, a perspective section and side view of the cutting arrangement.

My invention consists in certain improvements in machines for reaping and mowing,

- a a of this last bevel-wheel acarries on its inner end a cog-wheel, which gears into the cogs c insidethe driving-wheel c. Bythese means the revolution of the drivin g-Wheel will revolve the beve1-wheels and the crank c', and impar-t the required reciprocating motion to the cutter-bar. The outer end of axis ava is supported by a crank-lever, d, which is pivoted to the frame d in rear of the driving-wheel and bevel-gearing, the front end of said crank-leverreachingunderneath thedriversseat,where it is pivoted to the lowest arm of a three-armed lever, bbb'. The fnlcrum of this three-armed lever is about in its center, and the driver, by pressing his foot on the oneor the other of the upper two arms of lever b b', causes the leverthe bevel-wheel a can be brought into or out of lgearing with the bevel-wheel b, thereby either causing or stopping the motion of the cutter-bar. The arrangement of the gearing and crank d outside of the driving-wheel allows the driving-Wheel to be placed at its proper distancefrom the cutting machinery, so that when coming round it willjust run in the track previously made by the dividing-boardf" instead of on the cut grain.

The tongue T is placed about in a line with the driving-wheel, soas to allow the horses to walk on the side of the standing grass, and it is attached to the part of the frame nearest to the cutting machinery by means of a bent bar, i', in order to prevent side draft.

Another feature of the machine consists in the arrangement ofv the rake R. The rake is attached to the rear end of ahorizontal rod, m, which is pivoted in m' to an eccentric, i. The front end of rod m has a slot in which plays a pin, h', which extends upward from a slot in a secondary horizontalrod, u. This rod u is pivoted to the frame about in its center in n, and its end n3, opposite to the end which car ries pin fn', is provided with a friction-roller which plays in the groove of an eccentric, c', below the eccentric above mentioned. The revolution of the double eccentric i i, in combination with the said arrangement of the adjustable rods m and n, imparts to the rake its' proper motion. An adjustable plate, k, servesl ing or diminishing the velocity of the'motion In rear of the drivingwhee1, andof the rake. on the outer side of the rake, there is hinged to the frame a guard-board, s, which is to prevent the grass from being thrown round by the rake under the driving-wheel. f

The dividing-board f is horizontally hinged,

so that its inner edge can be moreor less turned from a 'vertical toward a horizontal position, thereby gathering the grain or grass'more or e d sse less closely. There is fastened to this vibrating cutterbar a plate,f, the rear part ot` which lies flat and slides on the finger-board in order to keep the same clear. The upper sides of the finger-slots are 4provided with concave bed-plates ze, their concave sides being placed toward the knives. The knivestare also curved instead of lkin g flat, and their concave surfaces are placed toward the concaves of the bed-plate fw. Knives and bed-plates are on their edges in close contact, so that they will continually sharpen eachother. The bed-plates are adjustable so as to 'make up for the wearing of the plates and knives, and to keep them a1- Ways in proper contact. These bed-plates 'w are shoe-pieces of steel, which may be taken out and sharpened or adjusted when necessary. The concave guard z, in its rear'ot the bedplates, has projecting 'guides y y, between which passes projecting plate .r upon the rear of the knives t, for the purpose of clearing out the grass and dirt which may lodge there.

What I claim as my improvements in reap. ers and mowers is 1. 1n combination with the driving-wheel placed inside the gearing, as above described, the angular tongue i for preventing side draft, and at the same time allowing the horses to Walk on the side of the standing grass or grain.

2. The above-described use ot' the balanced dogs b b under the drivers feet, for throwing the cutting apparatus in and out of gear. f

3. Making the parting and gathering board fhinged and adjustable, as set forth.

4. Regulating the size of the sheaves by means ot' the several ranges ot' gearing p p within the driving-wheel, in combination with the adjustable pinion r, as set forth.
