; srnemrmrion forming part of as latent Nd. 605,121, dated June 7, 1898.

4 of the United States, residing at St. Paris, in

the county 'of Ohampaign andState of Ohio, have invented a new and useful Corn-Harvester, of which the following is a specification;

This invention relates to corn-harvesters, and has for its object to improve the general construction of this class of machines, Whereby thedraft is-lightened'and'a single horse and one man enabled to harvest two rowsat- In addition to lightening the draft the labor of the operator is reduced to such an extent that the services of one person advantages of the invention reference is to be had to the accompanying drawings and the following description. A

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction withoutdepartingfrom the principle or sacrificing any of the'advantages thereof, and to 'a full disclosure of the invention an adaptation'thereofis shown in the accompanying drawings',in which;

Figure 1 is a perspective viewjof= a corn; harvester constructed in accordance with this invention. Fig. 2 is alyiew of themachine inverted. Fig. 3 is? transverse section. Fig.5 4 is a-detail view of a cutter, showing the manner of disposing the blades whereby they mutually brace one another. Fig. 5 is a detail view showing the manner of mounting the folding arm. V 4

Corresponding and like parts are referred to in the following description and indicated in the several views of the accompanyi'ng drawings by the same reference characters.

The platform 1 is mounted at'itsfront endupon a ground-wheel 2 and at its rear end upon caster-wheels 3 and is braced by longitudinal sills 4, transverse beams '5, and diagonally-disposed bars 6. v A shaft 7, hav

ing the ground-wheel 2 secured at an intermediate point thereto, is journaled at its ends in the longitudinal sills 4t and is provided at its ends with bevel-gears 8, which intermesh with corresponding bevel-gears 9, applied to the lower ends of vertical shafts 10, stepped inbearings applied to the sills 4. f The front end of the platformis cut away at an inter- :mediate point, forming an opening 11', in the rear end of which operates the ground-wheel 2,

and this opening is closed at its front end by a transverse barl2, secured at its extremities to the front ends of the sills 4, and to which are applied the shafts 13. Other openings are provided at the front end of the platform upon opposite sides of themiddle opening 11, forming side passages 14, into whichthe stalks pass to thecutting mechanism. The inner ends of the side passages 14 are inclined in- ,wardly and rearwardly and have cutters 15 applied thereto.

Vertical shafts"16 ,parallel with the shafts the cutting mechanism and platform. 7

fllates 23 are located at the outer sides of the passages 14 and form vertical walls to support the stalks in' their rearward travel through the passages, and the front ends of these plates are deflected outwardly andmade tapering, so as to gather in and elevate leaning stalks. Extensions 24 are applied to thetapering ends of the plates 23'and "incline downwardly and outwardly and consist of lengths of wire doubled upon themselvesfand secured at their inner ends to the plates. Standards 25 have their lower ends bent and secured to the platform and have the plates 23 attached thereto, the upper end of the rear standards being deflected so as to form a j keeper 26. Guards'are located at the inner side of the passages 14 and are formed of wire secured at its front end to the platform and at its rear end to a horizontal bar 27, located midway of the sides of the platform and elevated therefrom and supported at its front end upon a standard 2* and at its rear end by means of an inverted-V standard 2!. The rear portion of the guards inclines inwardly and the front portion is bent to incline upwardly, inwardly, and rearwardly in an opposite direction to the outwardly-bent end of the adjacent plate 23, whereby a flaring month is formed to receive the stalks and direct them into the side passage. The lower ends of the guards are bent rearwardly and secured to the front ends of the sills 4, as shown at 30. The horizontal portion 31 of the guards extends parallel with the side plates and with the outer portion of the sprocketchains and serves to support the upper ends of the stalks in their rearward travel.

A holder 32 is mounted upon the rear portion of the platform and consists of a stout wire or rod having its end portions bent, forming a holder of U form, and having the end portions bent vertically and secured at their lower extremities to the platform, the rear end of the holder being secured to the standard 2.) in any desired manner. The purpose of this holder is to receive the stalks and support them upon the platform in such a position as to admit of them being readily removed for forming the shock. A space is formed between the rear edge of each side plate 28 and the front end of the holder to admit of the operator gaining access to the platform for removing the stalks therefrom, and this space is closed by a pivoted bar 33, whose free end is received and held in place by the keeper 26. \Vhen the pivoted bars 33 are projected across the spaces, the stalks pass rearwardly to the holder without escaping laterally through the side spaces, and when the operator desires to gain access to the plat forin the pivoted bars are turned back out of the way, as will be readily understood.

The horizontal bar 27 comes midway between the side arms of the holder 32 and prevents the stalks received upon one side of the platform from toppling over at their upper ends and falling upon the opposite side of the platform, which would interfere with the free operation of the machine. An arm Si is hinged or pivoted to the rear end of the horizontal bar 27, so as to fold upon the latter and be turned into a horizontal position when desired for supporting the shock during its formation. \Vhen the machine is cutting the stalks, the arm Si is preferably folded upon the bar 27, and when the machine is at rest and the shock being formed the arm 3% is turned into a horizontal position and extends beyond the rear end of the machine, the stalks being placed so as to rest against the said arm, and after the shock has been formed and its upper end bound the machine is drawn forward, so as to release the arm 31: from the shock, as will be readily understood. The arm when folded alines vertically with the horizontal bar 27 and serves to support the upper ends of the stalks as the latter are received upon the rear portion of the platform and into the holder. The arm 3t is extended a short distance beyond its pivotal connection with the bar 27, and its extremity is beveled to match with the rear extremity of the bar 27, whereby the pivoted arm is held in a horizontal position when in service, as indicated by the dotted lines in Figs. 1 and 5.

A rotary cutter is secured to the lower end of each shaft 10 and cooperates with the cutters 15 and is composed of a series of blades 35, grouped about the shaft 10 and having the inner end of each blade abutting against the rear edge of the forward blade, whereby the blades mutually strengthen and support one another, as clearly indicated in Fig. The front edges of the blades curve rearwardly toward their outer ends and act in opposition to the inclined cutters 15 to sever the stalks by a shear action.

The machine is advanced over the field between adjacent rows of stalks by a single horse hitched to the shafts 13 and walking between the said rows, and the stalks enter the side passages 14 and are moved rearwardly by the sprocket-chains 21. with their fingers and are cut by the mechanism described herein and are received upon the platform within the holder 32. After a sufficient quantity of the stalks has accumulated to form a shock the machine is stopped and the stalks are removed by armfuls from the platform and placed against the extended arm 3i, and when the shock is formed and bound the machine is again moved forward and operates in the manner set forth. It will thus be seen that the stalks accumulate upon the platform 1 without requiring any attention on the part of the driver, the bar 27 preventing the stalks upon one side of the platform interfering with the stalks upon the opposite side of the platform, and after a sufficient quantity of stalks has accumulated to form a shock the pivoted bars or gates 33 are opened and the driver or attendant removes the stalks from the platform, armful by armful, through the spaces normally closed by the said gates 33 and places the armfuls of stalks in the rear of the machine upon the ground and against the bar 34., which has been turned into a horizontal position, as shown by the dotted lines in Fig. 1. This bar S-i supports the stalks during the formation of the shock, and after the shock has been formed and bound the bar is withdrawn from the shock when starting up the team. This manner of forming the shock obviates the use of tilting platforms, cranes, or operating mechanism for automatically dumping the shock upon the ground, thereby enabling the machine to be of light construction and draft, and comprises a minimum number of operating parts. The operation of removing i the stalks from the platform can be quickly performed and in about the same time as is generally required for straightening the stalks upon the platform and operating the mechanism for automatically placing the shock upon the ground and resetting the said mechanism for the next shock of that class of machines in which the shock is formed and bound upon the platform and dumpedupon the ground by mechanical appliances.

Having thus described the invention, What is claimed as new is I i 1.
