Be it known thatwe', FRANCIS M. WIDER- Our invention relates to an improved corn- A further object is to provide an improved A further object is to provide a corn-har- `With these objects `in view the invention ln the accompanying drawings, Figure 1 is Fig. Bis a Fig.`

Fig.

1 represents a series of parallel longitudinal to the transverse iron 2nM by a bolt 7 and nut 8, as clearly shown in Fig. 8, the opening in the iron 2 for the passage of bolt 7 being of sufficient size and the metal around the same beveled to permit of a slight hinged movement of the standard in any direction. The standard 6 is supported about midway between its ends in a bracket 9, having a threaded sleeve 10 therein,in which is mounted a screw l1,sup ported at its ends by inclined bars 12, secured to the bar 2-,and a crank 13 is provided on one end of the screw 11 to turn the latter and adjust the standard 6 laterally, and another screw 14, supported by an upright rod 14a at the front end of the frame, is swiveled into rhe bracket9 and provided with a crank-arm 15 to turn the screw and adjust standard 6 longitudina'lly of the frame, and it will be seen that by adjusting screws 11 and 14 the standard 6 can be supported in a vertical position regardless of the incline of the ground on which the machine is being operated.

A sleeve 16 is adjustably secured near the upper end of rod 6 by a set-screw 16a and carries another sleeve 17, preferably integral therewith and disposed at an angle thereto, or, in other words, approximately parallel with the platform'of the machine when adj usted to lie transversely of the machine and is provided with a set-screw 18 to secure a stalk-supporting frame 1da in place, which latter comprises a horizontal rod 19, carrying at its rear end a semicircular rod 2O to form a support for the corn, so as to dispose the same inL circular formation to form the shock,

as will more fully hereinafter appear. A hook 21 is provided on the rear end of rod 19 for the reception of a rope` or cable stay or brace 22, secured to the respective sides of the platform, so as to steady and brace the supporting-frame 18a, but which can be readily removed from the hook when the shock is to be dropped. l

The platform of our improved machine lcomprises a series of .hinged sections 23,' arranged, preferably, in pairs, two sections having their hinged edges disposed beneath each intermediate longitudinal iron 1 and each section comprising a board 24e, having one long edge madeconcave for the reception of a tube or pipe 25, and bolts 26 are passed through ICO the board and pipe to secure them together, as clearly shown in Fig. 9. The pipes 25 project beyond the boards at their forward ends and are supported in bearings 27 and 28, secured to the lower faces of forward irons 2 and 2a, and the hinged sections 23 are supported at their forward and rear ends when in their closed position by transverse bars 29, carried by L-shaped arms 30, secured on shafts 31, the shaft 3l at the forward end of the machine mounted in bearings 31u, secured to iron 2, and the shaft 31 at the rear end of the machine supported by a hinged frame 4l, as will be hereinafter explained. One arm 30 at each end of the frame of the machine-is provided with an upwardly and outwardly projecting lever 32, and a rod 33 is pivotally connected to the lever 32 at the forward end of the machine and adapted to be disposed in the bifurcated upper end of the lever 32 at the rear end of the machine and held therein by a pin 34, as shown, and a beveled shoulder or enlargement 35 (see Fig. 6) is provided on rod 33, against which the rear lever 32 abuts, to hold the same in its outward position to maintain the arms 30 beneath the closed sections 23. When it is desired to drop the hinged sections, it is simply necessary to disengage the rod 33 from rear lever 32 by withdrawing the pin 34, when the weight of the platform and the shock thereon will cause the rod 33 to rise by engagement of the beveled shoulder 35 with the lever 32 and force the hinged sections downward and permit the shock to drop, and beveled bars 36 are provided on the upper face of irons 1 to deliect the stalks and compel the shock to drop to the ground. In order to raise the hinged sections to their closed position, we provide each pipe 25 with an arm 37, projecting at right angles thereto and at an acute angle to the hinged section carried by the pipe, the arm 37 on every other or alternateV section being disposed parallel and connected at their free ends to rods 38 and 39, respectively, each of which is provided with a lever 40 for moving the rods laterally, and hence turning the pipes 25, through the medium of arms 37, to raise the hinged sections to their closed position, when the bars 29 are moved into position beneath the respective ends thereof, as above explained.

The shaft 3l at the rear end of the machine is supported in a frame 4l, (of which the rear transverse bar 2 forms a part,) hinged at one side of the machine and connected at its other end by a hinged bolt 42, having a set-nut 43 thereon to lock the frame 41 in place, but

which can be readily swung out of engagement with the frame 4l and permit it to be swung on its hinge, and hence be out of the way of the dropped shock.

To the front end of the machine, at each side thereof, a cutter-supporting casting 44 is provided, which latter are made with eyes or loops 45, supported on rods 46, carried by perforated lugs 47 on the forward iron 2, so as to permit the casting and mechanism carried thereby to be folded back on the frame and out of harms way when the 'machine is being moved from place to place and also permit of lateral adjustment of the casting and cutter carried thereby, as will now be explained. Each casting is made with slots 48, through which project threaded bolts 49, carried by iron 2, and set-nuts 50 are mounted on said bolts and adapted to be forced against the casting to lock the same against accidental displacement, but which can be loosened to permit the casting to be adjusted slightly or folded back on the frame out of the way. Each. castingis made with a bearing for a vertical shaft 51, on the lower end of which is secured a rotary cutter 52, and a protector is provided for said cutter comprising a series of fingers 53, bent over at their outer ends to inclose the cutter and present a blunt edge to the cornstalks, so asto deiiect the same into the 'cutter and not knock them down, as would be the case were the fingers straight and pointed, and these curved fingers also serve to protect the cutter from rocks and the like, as will be readily understood. Beveled gears 54 are secured on shafts 5l and mesh with beveled gears 55 on shafts 56, supported in bearings in the castings and carrying sprocket-wheels 57, which latter are connected with sprocket-wheels 58 by sprocketchains 59. The sprocket-wheels 58 are secured on short shafts 60 at the sides of the machine, and said shafts carry gears 61, meshing with internal gear-teeth on the wheels 4, so that the rotation of said' wheels bythe forward movement of the machine will operate the cutters.

The frame is provided at each side with downwardlyand outwardly projecting diverging guide-arms 61 to guide the stalks to the cutter, and said arms are connected to uprights 62 on the frame by rods 63, as shown, the uprights 62 serving as handholds for the operators or braces for their bodies while operating the machine.

Our machine is of such light draft that a single draft-animal is all that is necessary to draw the same, and hence we provide shafts 64, hinged to the frame, as shown, so as to permit the same to be swung up when not in use.

The operation of our improvements is as follows: A man stands at each side of the machine and grasps the stalks as they are cut by the cutters 52 and passes them back against the supporting-frame 18a until a sufficient number of stalks have been gathered to make a shock, when the machine is stopped. The shock will then be bound, the supportingframe 18a removed from the shock by either removing the rod 18a from the sleeve 17 or removing the sleeve 16 from the standard 6, the stay-rope 22 released therefrom and the hinged sections 23 of the platform dropped by releasing rod 33 from rear lever 32, the weight of the shock and hinged sections serv IOO IIO

4ing to force the'latter to fall. The rear hinged position and secured by the bolt 42 and the levers 40 operated to raise the hinged sections 23. The rod 33 is then secured in position to hold arms beneath the hinged sections and the latter in their closed position.

The corn-supporting frame 18a is then secured in position and the machine is ready to gather another shock.

Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of our invention, and hence we would havegit understood that we do not wishtto limit ourselvesl to the precise details set forth, but consider ourselves 'at liberty to make such slight changes and alterations as fairly fall within the spirit and `scope of our invention.
