Be it known that I, FRED I-IAZEN, a citizen of the United States, residing at Marysville, in the county of Union and State of Ohio, have invented a new and useful Improvement in Corn-I-Iarvesters, of which the following is a specification.

My invention relates to an improvementin corn-harvesters; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims. l

In the accompanying drawings, Figure l a top plan view of a corn-harvester embodying my improvements. Fig. 2 is an inverted plan view of the same. Fig. 3 isa side elevation. Fig. 4 is a longitudinal sectional view taken on the line a: of Fig. l. Fig. 5 is partly an end elevation and partly a vertical transverse section taken on theline y y of Fig. 1. Fig. 6 is a vertical transverse sectional view taken on the line w fw of Fig. 1. Fig. 7 is a detailed view of a modified form of the cutter-plate. Fig. S is an edge view of a portion of the sickle-bar.

A represents a pair of parallel longitudi-l nal beams, connected at their rear ends by a transverse beam B, the ends of which 'extend beyond the outer sides of the beams A for a suitable distance. s j

C represents a transverse beam of the same length as the beam B, which connects the beams A at a suitable distance from their, front ends. A pair of longitudinal beams D are secured 011 the ends of the beaml O and proj ect forward therefrom. Arranged in line with the beams D are a pair of longitudinal side beams E, which have their rear ends se-- and provided at the inner portions of their convex surfaces with longitudinal grooves I, and at the outer portions of their convex surfaces longitudinal grooves K are made in beams E. f (See Fig. 5.) l Transverse slits or openings L are formed near the front and rear ends of the convex sides of the platform, extending down into beams of the frame.

- M represents a pair of longitudinal pintlerods, which are arranged parallel. with the beams E, and extend through openings in the beams B and in the knees F, and on the said pintle-rods, near their ends, are pivoted arms N, which extend through and operate in the .transverse slits L.

O represents a pair of side platforms, which have their inner edges concave and provided with flanges l?, adaptedto enter the grooves I when the side platforms are in a vertical position, and with side Aflanges R, adapted to enter thegroovesK whenvthe side platforms are in a horizontal position. The said platforms are secured to the outer ends of the arms N, and are thereby pivotally connected to the sides of the central platform G.

The front end of each side platform is rounded and inclined downward, as shown. and said rounded portion is covered by a metallic plate S,the function of which is to prevent wear on the front end of the platform. Projecting from the front end of each side p latformare a series of fingers T, of the usual construction, in which slide cutter-bars U and cutter-plates V, which are secured on the upper sides of the cutter-bars bymeans of bolts or screws W. The front edges of the cutterplates are serrated, as shown, and the alternate serrationsor teeth XhaveA their edges beveledin opposite directions, as at a b, whereby they cut both ways. At the inner end of each cutter-bar is avertical yoke Z,provided with a vertical slot A.

B represents a driving-shaft, which is journaled in suitable bearings near the front ends of the beams A and D. To the central portion of the said shaft is secured a driving and supporting wheel O', having a broad tread. AThe upper side of the said wheelextends throutgrhV an opening in the head of the platform. Rigidly secured to the shaft B are a pair of Vbeveled gear-wheels D', whichV are arranged IOO between the beams A and D and face outward in opposite directions and have their upper sides also extending through openings in the head-platform.

E represents a pairof longitudinal shafts, which are journaled in bearings near the ends of the beam C. To the front ends of the said shafts are keyed beveled pinions F, that engage the wheels D', and rigidly secured to the rear ends of the said shafts are crank disks or wheels G', having the wrists H', which work in the vertical slots A' of the yokes, and thereby cause the cutter-bars and cutterplates to reciprocate when the machine is drawn forward,as will be very readily understood.

Under the rear corners of the main frame are arranged a pair of runners or shoes l', the front ends of which are curved upward, as shown. Vertical longitudinal openings K' are made in the rear ends of the said runners, and in the said openings are arranged circular disks or wheels L', which are mounted on shafts M', secured in the sides of the runners, the edges of the saiddisks or wheels being beveled on opposite sides, and thereby adapted to cut into the ground, so that the runners or shoes will slide upon the ground and support the rear corners of the machine and cause the disks or wheels L' to eut so deeply into the soil as to effectually prevent sidewise movement of the machine, and thereby direct the saine in a straight line parallel with the rows of standing corn, the machine having its main platform arranged between a pair of such rows of corn and its side platforms extended in line with and across the rows'of corn, so that as the machine advances the cutting apparatus at the front ends of the side platforms will cut two rows of corn simultaneously, as will be very readily understood.

On the front end of the main platform are arranged a pair of guard-frames M', at the innerends of which are inclined rods or standards O', on which are fitted adjustable kneerests P', the same being provided with setscrews R', by means of which they may be secured on the rods at any desired adjustment. A rod S' connects the rear upper ends of the guard-frames, and is provided at its ends with handles T' for the purpose to be hereinafter described. Y

Near the rear end of each side platform is arranged abundling-frame U', the said frame having the arms V' and the semicircular rearward-extending head WV' at the upper end of the said arms. The lower ends of the arms are hinged or pivoted to keepers X on the platform, and to an eye formed at the center of each head lV' is pivoted a supporting-rod Y', the lower end of which is adapted to engage a keeper Z on the platform, and is provided with an opening to receive a pin A2, whereby the rod may be secured in such manner as to support the bundling-frame in a vertical position on the platform. ly disengaging the lower ends of the rods Y from the keeper Z' the bundling-frames may be folded forward on the side platforms before the latter are turned upward vertically. on the sides of the main platform. When a sufficient quantity of the corn has aceumulated in one of the frames, it is tied into a bundle by hand and thrown from the harvestingemagehine, either upon the ground or onto a wagon, which may be trailed in rear of the harvesting-machine and attached to clevises C2 on the rear end of the main platform.

The guard-frame, with its handles and adjustable knee-rests, enables the operators to so firmly maintain themselves on the platform that there will be no danger of their falling onto the cutting apparatus and being injured thereby.

In practice one knee of each operator rests against one of the knee-rests p and one hand grasps one of the handles T', so that the l1a bility of an accident by reason of an operator losing his balance is avoided.

D2 represents a pair of rods, which have their rear ends pivoted to keepers E2 on the main platform, near the front end thereof, the said rods extending forward from the platform and having hooks F2 formed at their front end. Before bending the said rods to form the said hooks they are passed through a cross-bar G2, which serves to maintain. the rods parallel .to each other. The traces of the horse or draft-animal are attached to the hooks F2.

112 represents a curved guard supported on the platform and arranged over the wheel C', and I2 represents a pair of similar but smaller guards arranged over the wheels G.

In some instances it may be found desirable to dispense with the serrated cutterplates V and to substitute cutter-plates K2, having plane front beveled sharpened edges, therefor. One of such cutters is illustrated in detail in Fig. 7, these cutters reciprocating like the ones illustrated.

Having thus described my invention, I claim* l. The corn harvester having the main platform, the side platforms hinged thereto, the cutting apparatus on the front ends of the side platforms, and the bundling-frames on the said side platforms, having bow-shaped horizontal portions with legs bent down therefrom and hinged at their lower ends to said platforms, whereby the bundling-frames may be folded against the said side platforms, substantially as described.

2. The combination, in a corn-harvester, with the main platform and the side plat forms hinged thereto, of the bundling-frames hinged on the side platforms, having bowshaped horizontal portions with legs bent down therefrom and hinged at their lower ends to said platforms, the supporting-rods Y', hinged to the bundlingframes, and keep ers on the side platforms to secure the lower IOO IOS
