CORN-HUSKER.

SPECIFICATION forming part of Letters Patent N 0. 487,241, dated December 6, 1892.

Application filed April 11, 1892. Serial No. 428,687. (No model.)

To all whom it may concern.-

Be it known that we, OSCAR E. BEARDSLEY and OTTO BEARDSLEY, citizens of the United States, residing at Trempealeau, in the county of Trempealeau and State of Wisconsin, have invented a new and useful Corn-Husker, of which the following is a specification.

Our invention relates to a combined corn harvester and husker, the objects in view being totprovide a machine of cheap and simple construction adapted to strip the ears from the stalks, leaving the latter standing, remove the husks from the ears, to provide means for dumping the husks at intervals, and to provide means for delivering the ears after being husked.

Other objects andadvantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a plan view of a corn-husker constructed in accordance with our invention. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical longitudinal section of the same. Fig. 4 is atransverse section through the husking-rolls. Fig. 5 is a detail view of one of the spacing-blocks to maintain the proper intervals between the picker-bars.

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

1 designates the opposite side sills of the machine, and the same are connected near their front ends by a cross-sill 2 and near their rear ends by a cross-sill 3. Bearings 4 are formed on the under sides of the sills 1, and for rotation therein there is mounted a transverse axle 5, which extends to opposite sides of its bearings. Between the bearings 4. a ground-roller 6 is mounted fixedly upon the axle, and from the opposite ends of the axle, outside the bearings 4, extend forwardly-disposed hounds 7, the front ends of which are inwardly bent and embrace and are bolted to a draft-pole 8.

In bearing-eyes 9, depending from the under sides of the sills 1, near the front ends of the latter, there is mounteda transverse shaft 10, and the same also passes through a series of forwardly-disposed downwardly-inclined picker-bars 11, the upper sides of which,near their middles and toward their rear ends, are

cut out or curved, as at 12. The rear ends of the picker-bars are flat and rest against the front face of the cross-sill 2, whereby they are practically immovable. These bars are spaced apart by space-blocks 13, also perforated for the passage of the shaft 10.

Rising vertically from the sills 1 in rear of the centers of the same are opposite pairs of standards lat and 15, the latter being in rear of the former and slightly longer. The upper ends of these standards 14 and 15 are beveled or inclined toward the front, and each opposite pair is surmounted by an inclined sill 16, which extends at their front ends slightly beyond the side sills 1, before described. Bearing-eyes 17 are formed in the upper sides of the sills 16, and a transverse rock-shaft 18 is mounted for rotation in the eyes. Rockarms 20 are fixed to the ends of the rock-shaft outside the sills 16, and links 19 are pivoted at their upper ends to the rock-arms and at their lower ends to the hounds. A shaft-0perating lever is mounted on the rock-shaft 18 and designated as 22, the upper end of the lever being within easy reach of a driver perched upon the seat 23, placed upon the right-hand sill 16 for his accommodation. By operating the lever in the manner described it will be seen that the front end of the machine, at which the picker-bars are located, may be raised and lowered.

24 designates an inclined board, which is located between the sills 16 and is supported by the front pair of standards 14, and at its lower end by the sills 1, toward which it declines. This board has its upper surface covered with a series, of spurs 25. Above the board to the opposite inner sides of the sills 16 cleats 26 are secured, said cleats being inclined to the same degree as is the board 24, and to these cleats are secured the opposite edges of the upper inclined board 27, the lower face of which is like the upper face of the board 24, studded with spurs 28. The lower ends of the side sills 16 are arranged vertically above the curved or cut-out edges of the before-mentioned picker-bars andare provided with transversely-opposite bearings 29, in which is mounted a shaft 30. This shaft is provided with opposite loose sprocketpulleys 31. Near their upper ends the sills 16 are surmounted by transversely-opposite bearings 32, and in the same a transverse shaft is rotatably mounted, the ends of the shaft projecting beyond the bearings. Between its bearings the shaft 33 is provided with a pair of fixed sprocket-pulleys 34, and endless chains 35 connect the pulleys 34 and 31 and pass between the boards 24 and 27. The chains are connected by cross-bars 36, the whole constituting an endless carrier running in close contact with the upper sides of the picker-bars and inner sides or surfaces of the inclined boards 24 and 27.

The axle 5 is provided with a sprocket-.pul-

ley 37, and the same is connected by an endless chain 38 with a similar sprocket-pulley 39, located upon the stubble end of the transverse shaft 33, so that motion .is conveyed from the axle 5 to the shaft 33 and endless .carrier.

versely-opposite bearings 40 apair of parallel shafts 41 are journaled, and each shaft has rigidly mounted thereon a pair of contacting husking-rolls ,42. The rear shaft is extended beyond its hearing at the right side of the machine and carries a sprocket-pulley .43, which by a sprocket-belt 44 is engaged with and driven by a sprocketpulley 45, mounted on the corresponding end of the shaft 33.

Above the rolls 42 the front and rear pairs of standards 13 and 14are provided with longitudinally-opposite bearings 46,and in the same short longitudinal shafts 47 are mounted. Each of these shafts carries a small pair of sprocket-wheels 48, and they are connected by sprocket-chains 49, which at intervals are connected by cross-bars 50,the barsand chains constitutingan endless carrier. A pairof transverse bars 51 connect thefront standards to each other and rear standards to each other between the belt just mentioned, and at the' left side of the machine these bars are connected for about half their length by a platform 52.

Opposite the left end of the huski'ng-rolls a pair of hooks or brackets 54 project from the sill 1. These brackets removably engage with an endless inclined elevator or carrier 53, having the usual drive-wheel 54, which is connected by a chain 55 with a sprocket-pulley 56, located on one of the shafts 47.

' This completes the construction of the ma- .chine, and its operation is as follows: The machine moving toward the standing corn, the stalks thereof are gathered between the picker-bars 11 and coming in contact with V the cross-bar 9 or shaft upon which the bars are supported are bent down toward the ground. At this moment the ground-roller 6 reaches the stalks and serves to hold them, rolling along thereover while the cars which are too large to pass between the picker-bars are stripped rapidly from the stalks. As they are stripped they are received in the upper recessed edges of the picker-bars and are prevented from falling therefrom by the Between the standards 14 and 15 in ,transcurvature given the bars. At this point they are caught by the cross-bars 36 of the endless carrier and carried between the boards 24 and 27, where their husks are materially loosened. After passing through the boards they are delivered by the endless belt over the rear end thereof upon the platform 52, where they are caught by the cross-bars 50 of the transverse endless belt and dropped from the right-hand edge of the platform upon the husking-rolls 42. The same belt that delivers them to the husking-rolls also carriesthem over the rolls,

wh,ich,revolvin g inwardly, tear the husksfrom the ears, and as thus husked they are delivered by the aforesaid belt to the inclined endless carrier, heretofore described, located at the side of the machine, and by the latter are elevated and delivered into a wagon or other receptacle secured to the upper end of the carrier or following thereafter.

From the foregoing description itwill be seen that-we have'provided a machine of great simplicity and composed of few and simple par-ts and which is adapted ;to thoroughly gather and strip the ears of corn from the stalks and in such manner as to prevent pulling up of the latter, which willthoroughly loosen or slit the husks, and'fiually deliver them in such condition to the husking rolls, whereby their operation is facilitated and completed. By reason of the roller 6 it will be seen that the cornstalks will be held down against being removed from the ground as the ears are removed therefrom. A beveled pinion 60 is mounted on the end of the shaft 33 at the side of the sprocket-pulley 45, and the same drives through the medium of a second beveled gear 61 a shaft 62, carrying at its lower end a beveled pinion 63, which engages-and operates the gear v64 on the end of shaft 47. This shaft 62 is mounted in suitable bearings 65.

If desired, I may locate under thesills land below the husking-rollers a receptacle66, having a hinged bottom 67, which may be opened downwardly by a lever 68, extending up within easy reach of the operator. In this manner the husks may be delivered at intervals.
