CORN-HARVESTER.

SPECIFIGATION forming part of Letters Patent No. 688,167, dated December 3, 190i. Aipplication filed March 11, 1901. Serial N0- -621. (No model.)

To all whom it may concern:

Be it known that I, JOHN THOMAS GREEN, a citizen of the United States, residing at Lagrange, in the county of Lagrange and State of Indiana,have invented certain new and useful Improvements in Corn-Harvesters; and I do declare the following to be a full, 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in corn-harvesters; and it consists in the provision of apparatus whereby two or more rows of corn may be simultaneously cut and after being bound deposited upon the ground.

The invention will be hereinafter more fully described, and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form part of this application, and in which drawings similar letters of reference indicate like parts throughout the several views, in which- 7 Figure 1 is a perspective view of my improved corn-harvester. Fig. 2 is a top plan view. Fig. 3 is a sectional view taken on line 3 3 of Fig. 2. Fig. 4 is a front elevation. Fig. 5 is a detail of the dividing attachment. Fig. 6 is a detail view of means for holding the clamping-rope. Fig. 7 is a detail in perspective of a portion of the hinged frame and looking means therefor. Fig. 8 is a detail view in perspective of the means for pushing back on the table the stalks as they are cut.

Reference now being had to the details of the drawings by letter, A designates the platform of the machine, and B the drivingwheels, which are mounted on the axle B. Said axle has a gear B which is adapted to be thrown into mesh with a gear B by means of a clutch-lever B whereby said axle may be caused to rotate with the driving-wheels B. Mounted upon the platform are the upright rods 0, which are connected together at their tops by means of rods 0, forming a support for the hinged frame, which is mounted upon the top of the frame. any suitable location are the beveled gearwheels D, which mesh with the beveled pinions D, which are keyed to rotate with the vertically-disposed shafts D These shafts D have keyed near their lower ends the cuttin g-disks E, and immediately above said outting-disks are the fingered stalk -engaging disks F, the ends of which are adapted to project beyond the circumference of said cutting- .disks and to engage and feed rearward the stalks of corn as they are cut by said disks. It will be observed upon examination of the drawings that there are two sets of these outting-disks with upright posts similarly constructed and so located as to come opposite two rows of corn, which are adapted to be cut at the same time. Said shafts D are hollow and are journaled upon the upright posts 0 of the frame of the machine, and secured to and rotating With said shafts D near their upper ends, are the fingered disks F, which are similar in construction to the disks F, be fore described. These disks F are for the purpose of causing the upper ends or tops of the stalks to be fed rearward after the same have been cut. Said platform is made up of a series of parallel beams A,which are spaced apart, and in the spaces between said beams are the hinged tables A there being two of these tables between each pair of beams. Said tables are hinged at their outer edges to said rods A and journaled in the apertured ends of links G, mounted upon the axle B, is a shaft G, which is parallel to the axle B, and keyed to said shaft G is a crank G, having connection with the operating-lever H by means of link connection H. Also keyed to rotate with the shaft G are the crank-arms G3, which have chain connections G with the free edge of each of said hinged-tables, whereby as the operating-lever H 'is drawn back said tables are drawn to horizontal positions with their free longitudinal edges adjacent to one another, and on the reverse movement of said operating-lever the tables are allowed to drop down into vertical positions,as shown in dotted lines in Fig. 4 of the drawings.

The dividers for receiving the hills of corn each consist of a vertical rod K, which is journaled at its lower end in suitable bearings in one of said beams A, while its upper Keyed to the axle B at end is journaled in a bearingv carried upon the framework of the harvester. Secured to each end of said rod is a dividing member K,

having two curved arms K which merge toagainst one side or the other of the straight projecting portion K and the impact or the slight pressure of the stalks against said straight end will cause the member to tilt laterally, so that its opposite side will strike against one of the curved geared irons C of the framework. As the hill of corn strikes one of the curved arms the dividing member will be partially rotated, so that its free straight end K will be thrown againstthe oppositecurved rod 0 thus-allowing the next hillitoengage the curved arm on the opposite side, thus alternately dividing the hills onone side or the other of the central bar 0.

In order to compress-the shocks for bind-- ing, a rope L is secured at one end-to the frame, while its opposite or free end isheld within convenient reach of-the operator, whose seat is mounted nearthe central part of the platform, as shown in thedrawings, the top of said'seat being swiveled, so as to allow the operator to have access-to the various parts ofth-e machine while in operation. Thiscompressing cord or rope is secured at one" end to a block M, Fig. 6, having a clamping member M, pivoted over aslotted portion therein", in whichslotted portion the free end of the rope iscaught'and held by saidcla'mping member temporarily while the shock is being boundi In compressing the shock the operaton'passes the rope about the stalks and draws the cord tau t, and to hold the purchase while the shock 'isbeing tied the rope is caught in the slotted end of the. block Maud the pivoted tongue swung to the'position shown in Fig. 6. There are two of'these ropes similarl'y adjusted and loosely laid upon the-top of the frame to receive the stalks as they are cutby the disks.

Hinged to the collars O on the top rods'G of the frame is a hinged frame- N, which is adapted to swing away from the top of the frame: The longitudinal swinging endof the hinged frame'is adaptedto normally rest over the topof the frame adjacent -'to itsrear end, asshown'clearly in the drawings; This hinged frame isprovid'ed for the purpose of holding the stalks-and the shock" before the latter have been deposited upon the ground. To n'or-' mally hold thehinged frame in a locked relation'with reference to the frame, a catch Q is provided, which normally engages" a stop on-.one of the upright rods 0 of the frame. An 'operating lever Rispivoted to'thehinged frame,- as-at O andpasses through a loop S, which loopis-pivoted to one of the cross-pieces scene? of the hinged frame, as shown clearly in Figs. 1 and 3 of the drawings. Connecting said catch with the lever is a rod T, which as the lever is raised so that it contacts with the upper end of the loop S will cause said catch to -be released from the stop or lug on the frame and allow the hinged frame to be raised ver tically by a further forward movement of the operating-lever B, said hinged frame being lifted by the top as the lever is thrown forward. The shafts of the machine consist of two poles J,which have their rear ends forked and provided with bearings J, which are journaled over the axle B. These poles are preferably made, as shown in the drawings, adjacent to the drivingwheels, so that horses which are hitched onthe outside of each pole will be on-opposite sidesof the two'in'terve-ning rows of corn, the forward ends of the poles being connected together by means of the curved bar or yoke J which iscurved, as shown, for the purpose of clearing the tops of the stalks. I

In order to push the stalks rearward" from the disks as they are cut,I provide-push-plates W, which are L-shaped and are'mounted on spring-arms W,which are secured to the links G, connecting the two'parallel shafts B and G. As the wheels D rotate, the pins D ,.car ried thereby,will strike against the lug W ,secured to said plates'W, which will caus'ethe latter to spring back, and with theplatesth e stalks of corn will be forced rearward. As said arms are tiexible,they will return to their normal positions, which are as shown in the drawings.

In'op'eration thehills of corn in two rows are cut simultaneously, and at each-revolu-' tion of'the beveled gear-wheels the pins-D carried thereby will throw the presser-p'lates rearward; which will push-the stalks of corn onto the tables, and'when asuflicient quantity of corn has accumulated, resting upon said tables held in horizontal positions-and leaning against the swinging end" of the hinged frame, the machine is-stopped. The operator, grasping the free end ofthe compressing-ropecarrying theblock M, bywinding theropeonceabout thebunch of stalks and catching the rope-inthe slot-in the block M, compresses the shock by pulling the rope through the slot in said block andafterward bindsthe'samewith a-cord, and'turningup'on his seat binds the second shock, after which he pushes forward on theoperating-lever H, which through the-link H", connectedto the crank G, (the'latter being, keyed to the shaft G,) will cause the latter to rock; and with it the cranks G Fig. 1,- which have chain connections with the free edges :-of the hinged dumping-tables. As each tableA has similar connections with the shaft G, these tables A are thrown downward and the shocks fall tothe ground. By throwing the lever R upward the hinged frame'is thrown to a vertical position tofreethe tops of the stalks which arebound into shocks and the latter fall over upon the ground, after which the tables are thrown to horizontal positions and the hinged frame thrown down to a horizontal position.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

1. In a corn harvester, the combination with the platform,the gear-shaft and driving wheels, the upright frame, the rotary cutters and the fingered disks as described, the dividing mechanism mounted adjacent to the cutting-disks adapted to automatically throw the hills of corn alternately on one side or the other of the upright bars or rods of the framework, as set forth.

2.
