DANIEL B. BROWNING AND JOHN J. BROWNING, OF FAYETTEVILLE, MO.

IMPROVEMENT IN HARVESTER-DROPPERS.

Specification forming part of Letters Patent No. 152,211, dated June 23, 1874; application filed September 6, 1873.

To all whom it may concern:

Be it known that we, DANIEL B. Bnownme and JOHN J. BROWNING, of Fayetteville, in the county of Johnson and State of Missouri, have invented certain new and useful Improvements in Oombin ed Mowing and Reap ing Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to certain improvements in combined mowing and reaping machines.

In the drawings, Figure 1, Sheet 1, represents a rear perspective View of our improved machine complete. Fig. 2, Sheet2, is a detached side view of the hinged cutter-b ar frame.

Fig. 3, Sheet 2, is a detached sectional view of the double cranks and pitmen for operating the cutter-blades or sickles. Fig. 4, Sheet 2, is a transverse section of the cutter-bar and blades. Fig. 5, Sheet 2, is a detached view of the handlever attached to the main frame of the machine for adjusting the inner end of the cutter-bar. Fig. 6, Sheet 2, is a detached view of the double or brace hinge for connecting the couplingarm to the main frame of the machine. Fig. 7, Sheet 3, is a sectional perspective view of the grain receiving and dropping devices, showing the parts in a reverse or open position from that shown in Fig. 1.

Our invention consists in certain combinations and arrangements of devices and appliances, as hereinafter set forth and claimed, wherein- A represents the main frame, constructed of such form as to admit of placing the groundwheel B in advance of the driving-wheel B, and braced by means of a stout metal plate, 0, which is cast in one piece with the axles for the wheels B B. E is the coupling-arm, and

E the finger-bar attached to the main frame by means of double joints or hinges e e, the first one, 6, being of the brace form shown in Fig. 6, serving to rigidly brace the cutter-bar at right angles to the machine and prevent lateral play. The second hinge, c, joins the parts E E together at the inner end of the cutting apparatus. These hinges, e 0, allow free and easy movement up or down of the parts E E, with relation to the machine, to compensate for irregularities in the ground. Attached to the reel-post E on the finger-bar E is an angle-iron, d, through which passes a set-screw, d, which set-screw impinges against the leaf of the hinge c. This is an additional means for regulating the flexibility or altitude of the cutter-bar. The cutting apparatus consists of two blades, placed together and operated in opposite directions by means of gearing from the machine, and by double cranks and pitmen, as hereinafter described. The top blade at is attached to the under side of a plate, I), and the bottom blade a is attached to the top of a plate, I), so that the blades a a come flush together. Between the plates 1) b, separating them and forming a Way therefor, is a tongue, d". The plates b b, with the blades attached, are held and guided in their proper position by means of cleats g engaging over the flanges g g on the plates 1) b. Guards f f are placed at intervals over the cutter-blades, and also at the grain-board G, to guide the cut grain and to protect the blades. Attached to the fingerbar E is a post, E, to which post the reel H, deliverer or dropper I, and the cut-off J, with their connections, are attached. The reel H receives motion from the ground-wheel B ,throu gh the band h and pulley h. The deliverer or dropper I is operated by foot or hand, through the medium of a cord, 1', attached to the post i of the dropper, and to the treadle i on the platform of the machine. This post 2" is supported at its lower end on the rear curved projection L, attached to and supporting the finger-bar E E. The dropper is returned to its original position by a spring, at the lower end of post a". i is a friction-roller running under a curved way, if. Attached to the post 'l' is a bent stop, i which presses against a weighted pawl, i which pawl engages at its upper end with the front side of the nose 70 on the end of the cut off J, so that when the foot-lever i is operated to bring the dropper to the rear and at a right angle to the cutter-bar, to discharge its gavel, the cut-off J, by the action of the spring j, swings forward to support the falling grain. M is a bevel-gear wheel, running on the axle of the driving-wheel B. This wheel M eugages with a corresponding small bevelgear wheel, M, on a shaft, on. On the opposite end of this shaft m is a larger gear-wheel, N,which engages with a small gear-wheel on the under side of the machine, on the doubleerank shaft N, Fig. 3, Sheet 2. These double cranks operate the knives or blades a a in opposite directions by means of the pitmen F. O is the drivers seat, (shown in the drawings as broken oiifl) placed in any desired or suitable position on the main frame, so as to balance the same and give the driver a complete View of the whole machine. The driving-wheel B and the bevel-gear wheel. M are provided with a pawl and ratchet, to prevent backward turning of the worhin g parts of the machine. The graindivider consists of a hinged board, G, the rear portion G being curved and provided with holes w, as shown. Iivoted to this divider G is the arm K of the roller G This roller is adjusted and held in position by a pin, which passes through the arm K and through one of the holes m. In mowing, the reel, dropper, and cut-off are dispensed with..

By means of the dropper and cut-off operating in conjunction, as described, the cut grain is deposited in separate piles or gavels at the rear of the machine and outside the grain line. The amount of grain in a sheaf, or the time and place for dropping the grain,

is determined and regulated by the operator from his position on the machine, through the medium of the foot-lever, &c.

Having thus described our invention, What we claim as new, and desire to secure by Letters Patent, is r 1. The cutting apparatus, consisting of the blades to a, plates 1) b, tongue 01*, and cleats and flanges g 9, arranged in the front of the finger bar E and protected by the fingerguards f, substantially as described.

2. The combination of the cut-off J, provided with springj and nose or lug k, the dropper I i, constructed as described and shown, and the weighted pawl i all substantially as and for the purposes set forth. 1

3. The combination with the cutoff J and spring j, for retracting it, weighted pawl '5 dropper I, and spring i", for returning the dropper-cord '13, and foot-lever i", substantially as set forth.

In testimou y that we claim the foregoing We havehereunto set our hands and seals this 29th day of August, 1873.
