GEORGE N. CLEVELAND, OF FREELANDSVILLE, INDIANA.

'CORN-HARVESTER.

SPECIFICATION forming partof Letters Patent No. 500,055, dated June 20, 1893. Application filed May 28, 1892. Serial No. 434,782. [No model.)

To all whom it may concerm Be it known that I, GEORGE N. CLEVELAND, a citizen of the United States, residing at Freelandsville, in the county of Knox and State of Indiana, have invented certain new and useful Improvements in Corn-Harvesters,

View looking toward the right from the dot' ted line 3 3 in Fig. 1; Fig. 4 a detail view of one of the adjustable boxes carrying the larger wheel; Fig. 5 a detail sectional view of the adjustable box carrying the smaller wheel, and Fig. 6 a detail horizontal sectional view looking downwardly from the dotted line 6 6 in Fig. 3.

i In said drawings the portions marked A represent the frame-work of the machine; B and O the smaller and larger carrying wheels, respectively; D an intermediate shaft driven from the shaft of the larger wheel; E the vertical shaft to the cutter and reel; F a rotating bar, which is the main member of the rack for receiving the corn as cut, and G the thills or shafts whereby the machine is drawn.

The frame A is of suitable form to carry the mechanism, a preferred form being illustrated in the drawings. It is provided with bearings and supports for such mechanism, as will be explained in connection with the description thereof. Standards S extend up from this frame near the reel, and a guidebar S, of a form to aid the reel in gathering in the corn, is mounted thereon.

The smaller wheel B is mounted on a bearing block B, which is vertically adjustable in a preferably dovetailed groove or way in the adjacent portion of the frame A. The adjustability is provided for so that the cutting mechanism may be positioned nearer to or farther from the roots of the corn being out, according to circumstances.

The wheel 0 is larger than the wheel B, is fast on its axle, and carries the greater portion of the weight of the machine, and of the driver. A toothed pinion c is mounted on its driven.

axle O by means of which the mechanism is Said axle is mounted in adjustable bearings c 0 which are carried in segment: shaped ways ct a on the frame-work, whereby this side of the machine may be raised or lowered in positioning the cutting apparatus.

The shaft D has a pinion d by which it is driven from the pinion c on the axle 0'. At the other end it has a beveled gear wheel 61 which engages with a similar wheel on the shaft E, and thus drives said shaft and its mechanism.

The shaft E is arranged in a verticalposition, with its lower end stepped into a bearing 0. in the cross bar A of the frame-work, and its upper endv supported by a bearing a in the upper end of the bracket A which is mounted on said frame-work, and extends up wardly, as shown. Near the lower end it carries the beveled gear Wheel 6, by which it is driven from a similar wheel 61' on the shaft D; and below that is arranged a circular cutting knife or sickle E. Said cutting knife is circular in form, with blades somewhat similar to saw teeth. The cutting edges of these bladesare so inclined that when they come near to the stationary blade A below them,

in the final act of cutting, their points will be very slightly closer to said blades than their heels. They naturally force the stalks to be cut, somewhat to one side before actually cutting them, and this, together with the action of the reel, as will be presently explained, gives a shearing direction to the out, which is more certain, and requires somewhat less 'power than a direct cross-cutting movement.

There are two blades A and A secured upon the cross bar A of the frame-work directly below this cutter or sickle, which diverge from each other, and thus serve to gather the corn stalks to the apex, where they come in contact with said sickle and are cut. The blade A has a sharpened edge directly at the point where the sickle operates, which aids in the cutting operation. At the upper end of the shaft E is a reel composed of a hub, a I

greater extent than they are by said sickle and so, when said stalks are brought around to position for cutting, the ring and arms aid in securing the slanting direction most' desirable for the shearing out, as above stated.

This reel may be adjusted up and down on the shaft E by means of the hand-leverE or otherwise, so that it will operate more efficiently with the varying heights of stalks, it

being, of course, adjusted nearer the top ofthe shaft for the higher stalks, and farther down for the shorter ones. Above the knife or sickle E and surrounding the gear wheel e' constitutes a part of the frame-work, and which extends out parallel with the" bar F, also has arms a similar to the arms f which extend up and form the other side of the rack. Upon the end of the bar F is an arm J from which a connecting rod f runs forward and connects with the lever (preferably foot-lever) F The operation is, when the desired quantity of stalkshave been cut and deposited in the rack; that the driver releases the lever F permitting the bar F to rock in its bearings, which dumps the corn contained in the rack onto the ground. If desired, a laborer may come up behind the machine and lift the corn from the rack in his arms, instead of having it dumped onto the ground, as above de- 118th day of May, A. D; 1892.

The shafts G are similar in general form to those for many kinds of vehicles. They are scribed.

secured to the frame-work A by the pivots 9.

They extend back, however, beyond said pivadjusted to suit the varying heights ofani mals that draw the machine.

The machine as a whole is a simple and effective device for the purpose, requiring only a comparatively moderate amount of power to drive it, and it is easily kept in order, and adjusted to the required uses..

Having thus fully described my said invention, what I claimas new, anddesire to secure I by Letters Patent, isextend up therefrom. The timber A which i The combination, in a corn harvester, of the upright shaft E carrying the rotary sickle upon the lower end, the two blades A A se-' cured to the frame-work and converging toward the cutting point of said sickle, to one side of the shaft, a reel upon the upper end of the shaft, composed of arms, anda ring or center larger than the sickle, whereby the stalks are pushed outwardly toenable said sickle to have a shearing out, and a guide S mounted upon standardsiand curved to guide the stalks between the arms of the reel and.

around to the rearthereof onto the dropper, said several parts being arranged and operating substantially asshown and described.

In witness whereof Ihavehereunto set my hand and seal, at Indianapolis, Indiana, this GEORGE N. CLEVELAND. .[L. s.]' Witnesses:
