IMPROVEMENT IN CORN-HARVESTERS.

The Schedule referred-to in these Letters Patent and making part of the name Be it known that I, HENRY Fnnsnnn, of Springfield, in the county of Sangamon and in the State of 11- linois, have invented a new and useful Improved Corn- Harvester; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making a part of this specification, in which- Figure l is a top plan view'of my corn-harvester.

Figure 2 is a bottom plan view of the same.

Figure 3 is a side elevation of the same.

Like letters of like kind denote like parts in each figure.

- My'invention relates to a class of devices by which standing Indian corn is out, bound in shocks, and deposited upon the ground in a standing position at one operation; and

It consists, principally, in the general construction and arrangement of the various parts of the device, as hereinafter set forth.

It also consists in the arrangement of the droppingtables and of the devices for operating the same, as is hereinafter specified.

' In the drawingi A represents a suitable platform or body, mounted upon two traction-wheels, B, and'provided at its front, a little to one side of the longitudinal center, with-a notch, O, flaring outward, into which the standing corn may be guided by means of suitable jaws, not

,shown in the drawings.

The top of the platform all around this notch is armed with suitable sheet metal.

The rear of the platform is also provided with 'an opening, D, through which the shocks are dropped 'upon the ground.

This openingis-covcred with two dropping-tables, E and E, each'of which is semicircularin form. fit ting together so as to make a complete circle.

Each of these tables is pivoted at the center of its periphery to a lever, F, which in tnrnis provided with a cross-piece, G, the ends of which are pivoted upon the top-of the standards H, springing" from the cor here of the opening I).

For convenience of operating both levers at once, a cord, I, extends looselyfrom the top of one to the top of the other.

The inner corners of these tables are provided with rollers a, which traverse back andv forth in grooves I), provided in the front and rear upper sides of the openin D.

A guard, K, nearly a whole cirolejn form, with an opening toward the front of the machine, is constructed-ofsuitable hoops, in parallel horizontal rows, attached to bent standards, which spring from the corners of theopening D, and bend inwardly and then upwardly a sufficient distance, leaving the center of the space inclosed by the'guard directly over the center of the opening-D.

The hoops of the guard are also bent outwardly and form flaring jaws beyond the opening in said guard, and toward the front of the machine.

The rear end of the platform is furnished with two doors, L, meeting at the center, where they are fitted tightly, so as to remain closed, unless some force is used to open them. i

Upon the platform A, and directly behind the notch O, is the rack M, with suitable. standards, in parallel rows, to receive the falling stalks of corn, and retain them in place while being bound.

On the inner side of the rear end of the notch G, and playing horizontally close to the platform and over said notch from front to rear, isthe three-bladed knife N, constructed-with three curved blades, springing from a common center-plate, with their inward curves sharpened, with the cutting-edge downward.

This knife is properly secured to the vertical shaft 0, which passes down through said platform.

On each side of the notch O, and near its inner end, are placed the vertical reels P, composed of standards passing down through the platform, provided with inwardly-curved arms 0, which in their revolution pass by one another, and over the whole length of the notch O.

The operating-mechanism ofmy device is constructed as follows:

The axle Q, to which the traction-wheels B are firmly secured, passes through and is secured to the center of a vertical bevel-gearwheel, R, with its teeth on the side toward the notch G, which engage with and give motion to a beveled pinion, S, upon a suit able longitudinal'shaft, in proper hearings upon the under side of the platform.

The front end of this shaft is provided with another beveled pinion, T, which engages with and gives motion to a beveled pinion, U, in the lower end of the cutter-shaft O, and this rotates the knife N.

Upon one'side of the gear-wheel It another vertical beveled gear-wheel, V, is secured to the axle Q, at a point nearly in a .line with the standard of the reel P, which gear-wheel engages with a beveled pinion, d, on

the end of a longitudinal shaft, in suitable bearings upon the under side of the platform, the other end' of which shaft is provided with another beveled pinion,

- e, which in turn engages with and gives motion to a beveled horizontal gear-wheel, W, secured to the bottom of the standard of the reel 1?.

- A similar vertical beveled gear-wheel, X, secured to the axle Q, in a line with the standard of the reel P, gives motion to said wheel, through beveled pin ions f and g and beveled gear-wheel T, in the same manner-. that motion is given to the reel P The method of operation of this device is as follows:

Being driven afield with a suitable team, and in position such as will bring the rows of standing corn -nearly in a line with the notch U, the turning of the traction-wheels and the axle brings the reels into ro- 'tary motion inwardly, by the mechanism described,

the arms of which sweep the corn-stalks into the notch, where they are caught and severed by the blades of the rotating knife, to which motion is also imparted by the turning of the traction-wheels.

The stalks, when out, fall together into-the rack M, where they are bound into shocks by the helper, who stands in the rear of the reel P.

When a shock is bound, the helper stands it up upon the tables E resting against the guard Kuntil the spaceinclosed by said. guard is entirely filiedl Then, by pulling upon the cord I, the tables E E'-roll back in opposite directions, and the shocks fall through the opening D, resting on the ground in an upright posisition, convenient for curing or for removal. The tables E E then return, by their own weight, to their former position and close the opening D.

If the stalks are very tall, they will throw open the doors L by their pressure against them, which doors may then be closed by any convenient method.

By these devices great convenience, speed, and effectiveness will be gained at small cost, and without 7 great weight for a team to draw.

Having thus fully described the purpose, construction, operation, and merits oi my improvement,

l/Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The hereinbefore-described corn-harvester, consisting of the platform A, provided with the gatheringnotch O and the. opening D, the traction-wheels B, the dropping-tables E and E, the pivoted levers F and G, the standards H,, .the guard K, the gates or doors L, the rack M, the revolving cutter N, the shaft 0, the reels '1 and P, the shaft or axle Q, and the operating-gears, when the several parts are constructed and arranged to operate substantially as and for the purpose specified. V

Also, the arrangement of the dropping-tables E and E, provided with the rollers a and pivoted levers F and G, and working in the grooves b, substantially as and for the purpose set forth.

In testimony that I claim the foregoing, I have hereunto set my hand this 18th day of February, 1870.

HENRY FLESHER.
