SPECIFICATION formingpart of Letters Patent No. 466,018, dated December 29, 1891.

Application filed December 24, 1890. Serial No. 375,673. (No model.)

To all whom it may concern.-

Be itknown that I, MARION MOORE, a citizen of the United States, residing at Amanda, in the county of Fairfield and State of Ohio, have invented a new and useful Corn-Harvester, of which the following is a specifioation.

This invention has relation to corn-harvesters; and the objects in view are to provide a machine of cheap and simple construction that will harvest the corn, bundle the same into shocks, and which will spread the bases of the shocks so that they will readily stand after formation.

Various other additional minor features will hereinafter appear in the following description, and the novel features of the invention will be particularly pointed out in the claims.

Referring to thedrawings, Figure 1 is a plan of a harvester constructed in accordance with my invention. Fig. 2 is a front elevation, the machine being in the act of delivering a shock. Fig. 3 is a front elevation of the machine while in operation. Fig. 4 is a longitudinal section between the gathering-arms. Fig. 5 is a vertical transverse section. Fig. 6 is a detail in horizontal section of the shockcradle. Fig. 7 is a plan of the machine, the shock-cradle and elevator removed. Fig. 8 is a detail of the cranked cutter-shaft.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practicing my invention I employ a transversely-disposed oblong frame, comprising a front bar 1, a rear bar 2, and opposite end bars 3, connecting the front and rear bars, and to the former are secured the inner ends of a series of short bars 4, connected by a front bar 5, extending to one side of the adjacent end bar 3, and connected by a rearwardlydisposed end bar 6 to the corresponding end of the rear bar 2, and flush with the top of bars 3, 5, 6, and 2 is mounted a platform or covering 7. The front and rear bars are connected near their middle by a pair of rearwardlydisposed bars 8, which are in turn connected by a transverse bar 9'. Secured to the under side of the frame work is the draft-pole 10, of usual construction.

Upon a shaft 11, located at the left-hand side of the machine, is mounted for rotation posed shaft 19, through the medium of a pin- 7 ion 20, mounted on the shaft 19 and driven by the gear. The shaft 19 is provided at its front end with a bevel-pinion 21, which engages and drives a similar pinion 22, located at the inner end of a transversely-disposed cutter-shaft 23, mounted in suitable bearings located at the front of the frame-work. The cutter-shaft near its ends is provided with cranks 24, and loosely connected at their centers to these cranks are right-angularly-bent plates 25, to the lower ends of which are secured cutters or chopping-blades 26 outwardly and slightly upwardly disposed. The upper ends of the plates are hinged to the upper ends or pairs of straps 27, the lower ends of the strapsbeing hinged, as at 28, to the front bar of the frame-work.

Between the knives the shaft is covered by a forwardly-disposed platform 29, in the outer corners of which are journaled a pair of vertical rotatable shafts 30, having pinions within the platform meshing with and driven by worms 31 of the cutter-shaft. A similar pair of shafts 30 are secured to the front of the platform at eaclnside of the first-mentioned pair, and are also provided with gears engaged and driven by worms upon the cutter-shaft. Each of the vertical shafts 30 is provided near its upper end with a beveled pinion 33, and the two inner shafts at their upper ends above the pinions with radial gathering-arms 31.

In front of each of the vertical shafts 30 is secured an L-shaped standard 31, the outer ends of which are upturned and each end provided with abearing-opening 32. In each of the opposite bearings of each standard is mounted for rotation an inclined spiral feedshaft 33, the upper ends of the shafts extending beyond their bearings and there provided with small pinions 34, engaged with and driven by the pinions of the shafts 30. The two central L shaped standards have their horizontal branches converged toward each other and connected, so that they combine with the outer L'shaped standards to form converging guides for guiding the stalks of corn to the cutters or choppers, after which they are caught by the revolving arms of the shafts and thrown upon the endless carrier, which I will now proceed to describe.

designates a pair of opposite inclined side bars of an endless carrier, between the upper ends of which, between their lower ends, and between the outer ends of the front and rear bars 1 and 2 are mounted rolls 36, over which pass opposite endless chains 37 and an endless apron 38, designed to receive the stalks as deposited by the radiating gathering-arms and elevate the same over the discharge end of the elevator. The central roll of the rolls 36 has its shaft extended in rear of the bar 2 and there provided with a pulley 37, which is driven by a short endless belt 38, leading from a pulley 39, mounted upon the rear end of the shaft 19.

4:1 designates a movable platform or table provided at one side with a hinged arm 42 for supporting the cradle while being filled, as will hereinafter appear, said platform being mounted upon the fixed platform 7 at one end or side of the machine, and being connected at the inner edge of the same to the bar 3 by a pair of straps 43, pivoted at their outer ends to the platform 41, diagonally disposed to the rear of the machine and pivoted at theirrearends to the bar 3. The platform *1 is locked in position by means of a spring catch 44, which takes over the under edge of the hinged arm 42, which latter at its extremity is provided with a notched standard or saddle 45, which supports the small end of the cradle, hereinafter described, and at the outer rear corner of the platform is located a swiveled rotatable key The mechanism just described is designed to support in a movable manner the cradle in which the shock is formed subsequent to the delivery of the stalks by the elevator over its delivery end into the cradle. The cradle consists of a central beam 46, provided with a transverse restbar 47 to steady it, the front end of the central beam terminating in a rounded tenon or head 48, removably connected by spring 50 with the outer end of a swinging bar 4:9, pivoted to the front bar 5 of the frame-work. Behind the transverse bar 47 a recess is formed in the under side of the bar 46, and therein located is a loose roller 51. The cradle consists of two halves 52 of a coneshaped cylinder, hinged at their lower edges, as at 53, to the opposite sides of the bar 16, one-half of said cylinder being provided at its upper edge with a hinged door 54, designed to form a continuation of the cradle when locked in position by means of a pair of hooks 55, secured to the opposite section. The cylinders are adjusted so as to open and close by a U-shaped bail 56, pivoted at its center transversely in the bar 46 and having its opposite branches inwardly turned to bear against the opposite cylinder-sections. In front of the bail and in the under side of the bar 46 is formed an oblong socket 57,

adapted to fit loosely over the upper end of the swiveled keytti Between the cylindersections there is secured to the upper side of the beam 46 a vertical partition 58, to the front edge of which is hinged at opposite sides a pair of semicircular wings 59, having hinged near their outer ends a pair of straps 60, which straps are loosely pivoted at their inner ends opposite the front end of the partition to the front end of a rod 61, adapted to operate the wings by spreading them laterally from the partition or folding them substantially in line therewith. At one side of the beam 46 asmall basket 62 is located, and in bearings 63 upon the upper side of the beam is mounted a windlass (it to receive the tying-cords from the basket.

In operation, after the stalks have been fed to the cutters, cut, and delivered upon the endless apron they are carried by said apron over the delivery end of the same, where they are dropped into the cradle, the door of which is swung back and the sections of which are separated or swung open, so as to admit the stalks. The wings 59 are set so as to extend laterally from the partition, and the partition serves the function of equalizing the distribution of the stalks to the opposite cylinders. The butts of the stalks become disposed in a circle around the edges of the wings and are thus spread or diverged from the center of the shocks, so as to form a flared base upon which the shock can safely rest after its formation and withdrawal from the cradle. By pulling the rod the wings 59 are opened, and by pushing the rod it, through the medium of the connecting-bars G0, which are hinged both to the rod and wings, serves to close or swing the wings together in the direction in which the rod travels. During the operation of forming the shock the wings are spread, but after the shock has been formed they are closed. After a sufficientquantity of stalks has been deposited in the cradle, the binding-cord is passed around the end of the same, which, it will be observed, projects beyond the small end of the cradle, and by means of the Windlass said bindingcords are drawn taut and their ends tied, after which they are cut and the operation of delivering the shock begins. The attendant grasps the handle 47 of the keel-piece or rib of the cradle and draws the same with the platform and cradle to the rear and to the right, and the cradle is then turned'so that the broad end of the cradle is toward the carrier. lVhen moving to this position, the keel-piece swings upon thepivot 46*, and the bar or arm 4-9, swinging rcarwardly upon its pivot, reaches aposition nearly in line with the keel and automatically disengages at its hook end with the rounded end of the keel. In the movement of the cradle the small end thereof is supported by the hinged bar 42 in the cradle, at the free end of which rests the roller on the under side of the rib. After reaching the position mentioned above, the movements of the cradle and bar 42 are continued until the small end of the cradle is to the front, at which time the roller of the keel thereof leaves the saddle of the arm 42, and the movement of the cradle serves to ride the roller and small end of the cradle up the inclined guide 65, so that the cradle is inclined until the rounded end of keel thereof rests upon the ground, the keel pointing toward the opposite side of the machine, after which the cradle and the shock are lifted to a vertical position. The cradle is now removed from the shock, which latter is left standing, and the parts replaced.

From the above it will be observed that I am enabled to construct a comparatively cheap and simple machine, adapted to automatically gather the stalks, chop the same, deliver the stalks upon an apron and thence into a shock-forming cradle, and finally deliver the stalks from the cradle, all in one continuous uninterrupted operation. It will also be noticed that the knives are outwardly and upwardly disposed, so that they cut upon an incline and in an upward direction away from the roots of the stalks, and hence have a tendency to facilitate a complete severance, more so than when chopping down, which is liable, provided the knives are not in prime condi-- tion, to mash the stalks or bend them to the ground.

Having thusdescribed my invention, what I claim is- 1. In a corn-harvester, the combinatiomwith.

a horizontal cutter-shaft, means for operating the same, cranks formed in the shaft, cutterplates hinged at their centers to the cranks and loosely connected at their rear ends to the frame-work of the machine, horizontal knives secured to the lower edges of the cutter-plates, and gears mounted on the cuttershafts, of a series of vertical rotatable shafts mounted in suitable bearings, provided at their lower ends with gears engaged and driven by the gears of the cutter-shafts, pinions mounted on the upper ends of the shafts and gathering-arms mounted above the pinions, an L-shaped standard secured in front of each vertical shaftand provided at its ends with bearing openings, and spiral shafts mounted in the bearing-openings of the brackets and each provided at its upper end with a beveled pinion engaged and driven by the gear of its adjacent vertical shaft, substantially as specified.
