IMPRQVEMENTIIN HARVESTERS.

The Schedule referred to in these Letters Patent and maldng part of,A thesame.

To all whom it may concern Be it known that I, HENRY WATERMAN, of Williamsburg, in the county of Kingsand State of New York, have invented an Improvement in Machines for Reapiflg and Mowing; and I -do hereby .declare that the following is a full, clear, and exact description thereof", referencevbeing had to the accompanyingdrawing. making part lof this specification, in Which- Figure 1 represents a section taken vertically through the center of the machine;

Figure 2 is a'plauef the machine;

Figure 3 is one of the fingers, showing the' knife in'section; and t Figure 4 is a detached view ofthc fiexible detlector.

My invention consists in .certain improvements iu machines for reaping and mowing, whereby thc cutting-is facilitated and clogging prevented, andthe rlhe cutter-bar is connected at eachend by. pivot'- joints to the arms a a, which vibrate about thelixed centers b b.

The end c of the cutter-bar is attached by a pivot'- joint to the-'connecting-'rod d,- which takes hold of the bell-crank e upon the pinion-shaft i, which last receives its motion from the'main drivingwheel g, through the medium of the inner gear h, pinion i, and bevel-gear It t'l From this mode'ofittaching' and operating the cutter-bar, it will be seen that it, with its knives, has au advancing and retreating curvilinear' motion, 'which secures the advantage ofa draw-cut, and is the motion -best suited to clear the spaces between the knives and the lingers. The range of motion being greater than in the straight reciprocating'cut, I adapt the cutting and clearing-edges 'ofthe knives'to their proper action by using two sets of knives or cuttingedges, viz., the projecting knives b' b andl the inter-I mediatev knives or edges a a.`

Both these knives perform the otiices of'cutting and clearing, and while the cut is effected with more ease than with the usual rectilinear motion of the cutter'v bar, the clearing is e'ected in a very perfect manner.

The knives may be`made in auygot the well-known forms not inconsistent :with my pecular action, and the lingers m m, 85o., I in ake elastic, instead of make' ing them firm and unyielding, as they are` usually from being made of cast-iron.

A twofold purpose is thus accolnplished bythe elastic ngers,'viz., when sticks or any obstructing material get between the lingers and knives, the spring of the fingers admits ofits being easily dragged out by 'the retracting motionI of the knife.

For the purpose of depositing the grain on the ground in given quantities, the grain, as it4 is cut and -delivered by the reel falls upon a cradle, and when the required quantity has been collected, the cradle is libn erated to drop its load of grain, and as this is being delivered, the gra-iu which is being cut is caught and held by an interposed cradle.

The mode of construction in which this mode of operation is embodied, consists of .four cradles, p p p p,

composed each of a seriesof parallel bars, attachedto arms projecting from a shaft, n, mounted to turn in suitable bearings, as represented in the accompanying drawing.

Near one end of the shaft n there is a count-wheel, r, having fourholes sin its periphery', at equal dis tances apart, to receive a check-pin, t, on a spring1 u, and the holes for the check-pin are so located rcln- Atively to the cradles as to-hold any one of them in thc required position to receive the grain when cnt and thrown back by the reel operating in the usual way;

Nearvthe seat of the driver, so as to be easily reached and operated by him, there is a handle, e', on the end o f a sliding rod, s, hy means of which, so soon as a Sutlicient quantity of grain for a-gavel, has been collected on the cradle, the driver can depress the spring u, and thereby disengage the checkpiu from one ofthe holes in the count-wheel, so that the weight of thegrain which `has accumulated on the cradle may turn it, and be discharged, and in sodoing the next cradle is brought. in line and stopped by the check-pin cnterin g the next hole in the count-wheel. In this way, the discharge of one gavel brings into position another cradle, to catch the next cut grain, to be in turn discharged in like manner..Y

As the grain is laid across the swath, it is turned so as to lie in the direction of the swath 'and .be out of the way'of the horses at the next cut, by means of a detlectorof a peculiar description. This'defectory is.

attached to the rear end of the guard or side-board,

and is made of a flexible strip, a', of metal or other larities and obstructions .upon the lsurf-atleet" the field.

l I do not claim the advancing and retreating curvi-v linear motion of the cutter-bal', but

I claiml. The combination of the two sets of knives de scribed, with the cutter-bar having a curvilinear mo- -t-ion, as set forth.

2. The shifting-cradles; substantially as described, nounted on the frame or platform of `a. reaping-machine and placed across it. so as Vto -be parallel, or

as set forth.

nearly so, with the cutter-bar, and so arranged,- as described, that when one of them is liberated `to discharge a gavel of grain, another shall take its'place to catch the grain that is next to be cnt, as setforth.

3. The iiexible deector, constructed and operating HENRY WATERMAN. Witnesses:
