CORN-HARVESTER.

SPEGIFICATION forming part of Letters Patent No. 570,832, dated November 3, 1896.

Application filed October 5,1895.

To @ZZ whom, 'it may concern:

Be it known that I, MASON 0. VERT, a citizen of the United States of America, residing at Poplar, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Corn-Harvesters; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, ret'- erence being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide a corn-harvester of such construction that two rows of corn can be harvested at the same time and in which the cutting mechanism can be raised and lowered so that the stalks can be cut at the desired height from the ground.

The invention consists in the particular construction and combination of the parts embodying the construction of a frame and adjusting means for the cutters, as well as the construction of the carrier belts between which the stalks pass and the tilting platform upon which the stalks are received and the shocks formed.

In the accompanying drawings, forming part of this specification, Figure l is a side elevation of a corn-harvester constructed in accordance with my invention. Fig. 2 is a plan view. Fig. 3 is a rear elevation. Fig. 4 is a detail perspective view of one of the endless chains, the upper part of the slats being broken away and indicated in dotted lines. Fig. 5 is a detail sectional View ofthe gear-wheel carried bythe main axle with the pinions in mesh with .the gear-teeth thereon. Fig. 6 is a detail view showing the manner of gearing the rotary cutters. Fig. 7 is a detail view of the sprocket-chains, illustrating the manner of arranging the vprojecting fingers thereof.

A designates the main 'frame of the machine, which is supported at its rear end upon the axle B of the supporting-wheels and at its forward end by a caster-wheel a', the stock of which bears in the transverse beam a of the main frame. The draft mechanism is connected to the beam a in any suitable manner.

The axle B is adapted to rotate with the supporting or driving wheels, and said axle Serial No. 564,726. (No model.)

has mounted centrally thereon a gear-wheel B', the rim of which is provided on its inner side with gear-teeth b and on its periphery with sprocket-teeth b', this gear-wheel being adapted to drive the stalk-cutters and endless carrier-belts, as hereinafter described.

Upon the axle B, on each side of the gear-l Vinclination by brace-rods b4, which extend to a movable part of the machine for the purpose hereinafter set forth.

Upon the forward part of the main frame A is journaled a transverse shaft D, having an operating-lever d, provided with a sliding dog, which engages a segment-rack d', projecting from the beam c, so as to hold the shaft in an adjusted position. The shaft D has rigidly secured thereto a rearwardly-projecting segment D', to which is attached a iiexible connection or chain (Z2, said chain being connected to the center portion of a transverse beam F to support the same with respect to the main frame.

Upon each end of the beam F is rigidly secured an upwardly projecting frame or bracket F', having bearings ff for a vertical shaft E, upon which a stalk-cutter Gis mounted, said stalk-cutter being in the shape of a disk having a serrated cutting edge. The vertical shaft E also has a bearing in the transverse beam F and the cutter lies between said beam and a horizontal portion of the upright or bracket F. It will be understood that this construction is duplicated at each end of the beam F. The upper ends of the shafts E are provided with bevel-wheels e, which mesh with bevel-wheels e at the en'ds of a transverse shaft E', which is driven from the driving gear-wheel B' by means of a sprocketchain c2 passing over a sprocket-wheel on said shaft. The shaft E passes through curved guides or standards a2, secured to the side pieces A of the main frame, and also through IOO the upper end of the uprights or brackets l1", so as to retain the gear-wheels e in mesh with the gear-wheels e. It will be noted that by the construction and arrangement hereinbefore described the height of the cutters G can be regulated by manipulating the lever (Z, and held in an adjusted position by causing the sliding dog on the lever to engage one of the rack-teeth of the segment-rack d.

H II designate longitudinal beams upon which the endless carrier-belts are mounted, and near their rear ends these beams rest upon the axle B, being loosely connected thereto by U-bolts or other suitable connections. The forward ends of the beams H are supported by brace-rods which extend from the axle B and adjustable crossbeam F and are connected to parts carried thereby, as hereinafter more fully set forth. Through the ends of the beams l-I pass vertical shafts I I', which extend a considerable distance above said beams and are provided with sprocket-wheels t' and t", around which pass sprocket-chains K, to which the slats 7.; of the endless carrier-belts are attached. There are two longitudinal beams II on each side of the machine and consequently two carrier-belts between which the cornstalks pass. The carrier-belts are driven from the shafts C C by the bevel-wheels c meshing with bevel-wheels 2 on the lower ends of the vertical shafts I, carried by the inner lon gitudinalbeams H ,the shafts I being geared to the adjoining shafts by gear-wheels t3, as shown in Fig. 3. This gearing is located at the rear end of the machine, so as to leave an unobstructed passage between the belts at the forward end. The carrier-belts are supported in a vertical position and parallel with each other by bracerods which extend from the upper ends of the shafts I and I to the axle B and crossbeam F, the brace-rods Z and Zr', which extend from the upper end of the shafts carried by the inner beam H, being connected to the cross-beam F, while the brace-rods Z2 and Z3, which extend from the shafts carried by the outer beams H, are connected to the outer ends of the axle B, a supplemental brace-rod Z4 extending from the upper end of the outer shaft I to the outer end of the beam F. By this manner of bracing the carrier-belts and connecting them to the vertically-adj ustable beam F, which carries the cutters, said carrier-belts are tilted when the beam is adjusted, and by means of the connecting-rods 114 the bevel-wheels on the ends of the shafts C are held in mesh with the bevel-wheels on the shafts of the carrier-belts when the parts are adjusted to any desired position.

M designates a tilting platform which is pivoted a little forward of its center to the axle B, and this platform is held in a horizontal .will be deposited upon the ground.

ported by the side pieces of the main frame and is provided with an operating-lever n and with rearwardly-proj ectin g arms n,which are connected to the catches by short chains n2. Upon this platform the attendants stand while receiving the c ornstalks from the endless carrier-belts and making them up into shocks, the stalks being placed against the sideboards m and guide-rail m2 until a suficient number have been gathered to form a shock.

In front of the tilting platform is located a supplemental rigid platform M', which receives the stalks, as hereinbefore mentioned, and upon this supplemental platform the attendant stands after placing the shocks at the rear portion of the tilting platform, and by operating the rock-shaft N said shocks The boards which make up the stationary plat-- form h are secured to the under side of the longitudinal beams A', and the forwardlyprojecting beams of the tilting platform rest thereon wh en said tilting platform is in a horizontal position and in engagement with the catches.

To the under side of the longitudinal beams II are secured guide-plates O, which extend from the cutters G in an upward inclination to the platform M. These guides receive the ends of the stalks after they leave the cutters and guide them to the platform.

Each alternate link of the sprocket-chain K is provided with an upwardly-projecting portion k, to which the slats lo are attached, and with an outwardly-projecting finger k2, which projects into the space between the carrier-belts and pushes the stalks along to the platform. The fingers of one of the carrier-belts are formed on the upper plates of the links, while those of the adjacent belt are formed on the lower. plates, so that when said fingers enter the passage-way between the belts the fingers of one belt will overlap the fingers of the other.

From the foregoing description, in connection with the accompanying drawings, the operation of the machine will be readily understood, it being borne in mind that two rows of corn are harvested at the same time and the draft-animals walk between the rows.

What I claim as new, and desire to secure by Letters Patent, is-
