T0 aZZ whom, it may concern.-

Be it known that we, NELs LOGAN and IVER I. FLO, citizens of the United States, residing at Albert Lea, in the county of Freeborn-and State of Minnesota, have invented a new and useful Corn-Harvester, of which the following is a specification.

Our invention is an improved corn gatherer and husking machine; and the object of our improvement is to produce a machine which can be driven through a corn-field, covering two rows of corn at a time, strip the corn from the stalk, dispose of the latter to the rear of the machine, husk the ears, and then elevate them into a wagon accompanying the gatherer and husker.

Another object of our invention is to devise a machine of this kind light enough to be drawn by two or three horses, according to the nature of theground and the stand of corn.

In brief, our device comprises a wheeled frame adapted to move across the field transversely to the rows of corn, of a drum mounted thereon carrying grabbers, a blade for tearing the ear from the stalk, and means arranged in the rear of the drum for stripping the husk from the ears and depositing the latter in a wagon-box, all of which is fully shown in the accompanying drawings, in which- Figure 1 is a plan view of our machine complete. Fig. 2 is a rear view of the same. Fig. 3 is an enlarged detail view illustrating the relation of the horizontal and obliquely-arranged huskingrollers. Fig. 4 is an end view of the complete machine. Fig. 5 is an enlarged detail view illustrating the means for tilting the machine. Fig. 6 is a detail view in perspective of the guide-brackets between which the rear end of the draft-pole iits. Fig. 7 is an enlarged plan view showing the arrangement of the gears and sprockets for operating the husking rollers and COHVOIYGY- belts, respectively. Fig. 8 is an enlarged sectional view drawn through the husking-rollers. Fig. 9 is a detail view of one of the cleats that are fastened to the conveyer-chain. Fig. 10 is a detail perspective of one of the fingers that are fastened to the drum for the purpose of stripping the ears of corn from the stalk. Fig. 11 is a detailed perspective Serial No. 137,900. (No model.)

view showing the projecting platform and' rods.

In carrying out our invention we employ a frame A, through which passes a revoluble axle B, the axle being rigidly secured at one end to a bull-wheel C and at its opposite end carries loosely mounted thereon an ordinary wheel C; Rigidly secured on this axle between the frame and the wheel C is a sprocketwheel 1). Journaled in suitable bearings E in the upper part of the frame is an axle E, the end toward the wheel C projecting outwardly and carrying a sprocket E Mounted upon and rigidly secured to this upper axle is the revolublehollow drum F. Upon this drum are sets of fingers F, formed integral with the plates F which are bolted to the drum and curved to lie parallel to but at some distance from the outer face of the drum. The lingers are arranged in two series, sets being located adjacent each end of the drum, each set being in alinement with the other sets of its series and the various sets being ninety de grees apart. The length of the drum and arrangement of the lingers is such that each series will engage the cornstalks growing on adjacent rows. ivlounted above the drum is a frame G, supported by the inclined arms G, and the frame is curved to correspond to the curvature of the drum and is a suflicient height above it to permit the lingers F to pass freely beneath it. Adjacent each end of the frame are secured the oppositely-inclined cutting blades G adapted to sever the ears from the stalk and cast the latter to one side.

In the rear of the sprocket I) is journaled in the frame A a short shaft H, which carries at its outer end a sprocket-wheel H. Intermediate its ends this shaft carries a bevel-gear H, which meshes with a gear H, to be hereinafter described. At its inner end the shaft H carries a gear H, which engages a gear H mounted on one end of one of the huskingrollers described below.

At right angles to the shaft H is the shaft H which carries the beveled gear H at its outer end, and on this shaft are rigidly secured the sprocket-wheels I the shaft being rotated through the medium of the bevel-gears If. H3.

To the rear of and below the drum are two sets of coacting rollers J J, reduced at the ends and journaled in the frame A adjacent the frame A. The reduced end of the roller J carries the gear H and derives rotary motion therefrom. The roller J is journaled in yielding bearings J the roller being held in contact with the roller J by a spring J bearing at one end against the frame and at its opposite end against the bearing J and the rollers are thus adapted to momentarily separate and permit hard substancessuch as sticks, gravel, and the liketo pass between them. At the outer end of the rollers J J is an elevator A, supported by uprights A and in this elevator, journaled in its upper and lower ends, are the rollers K K, corresponding to the rollers J J, the adjacent ends of the rollers J and K being connected by a universal joint L, the roller K being similar in construction to the roller J. All of these rollers are circumferentially grooved, as shown at M, and adjacent these grooves are arranged a row of pins, the pins on one roller alining with the grooves on the coacting roller, and as the length of the pin is slightly in excess of the depth of the grooves the rollers are alternately separated and brought together again by means of the action of the pins h and springs J At the upper end of the elevator are mounted two sprocket-wheels I, corresponding to the wheels H, and an endless link-chain conyeyer N runs over these wheels, passing upwardly above the rollers J J K K and downwardly beneath them. At the junction of the rollers the link chain passes over the idle sprockets O. Cleats N connect the two chains and complete the conveyer, the inner face of the cleats extending centrally inward, presentinga wedge-shape appearance in cross-section, the tapering point N traveling between the upper surfaces of the coacting rollers.

In front of the machine is located a fender supported from the main frame, comprising a forwardly and downwardly projecting platform P, formed with an edge P, the sides tapering to a point P. On either side of the platform are a series of downwardly and forwardly extending rods P, the rods being graduated in length, the inner ones the shortest. Flanking these rods and secured to the main frame are the side guards Q, which are inclined downwardly and forwardly and then project forwardly in a line parallel with the ground. The object of these various parts is to gather the cornstalks that may be bent over, broken, 01' lying upon the ground.

A tongue R and the usual trees are secured to the frame, and supported by a suitable spring-bracket S is the seat S. Pivoted to the rear of the seat and extending to one side of it is the lever S. A supplemental lockinglever S is pivoted to the lever S at the handle portion and is connected to a spring- ,To drive the mechanism described, a

sprocket-chain T passes over the sprocketwheels D E H and the idler T.

In operation the harvester is accompanied by a wagon having a box-bed, which is driven upon the conveyer side of the machine. The platform or fender P passes between the rows of corn, throwing such stalks as may be in its path to one side. The guards Q will pass on the outer sides of the two rows and at a point low enough to catch and pull over all corn that might be bent away from the path of the machine. The stalk will be caught between two of the fingers and will slip through same, the ears being separated from the stalk by the blade G and carried beneath the drum. The ears will then fall upon the rollers J J and the shuck will be caught between same and stripped from the car, which will of course be carried at the same time toward the Wagon by the cleats moving above the rollers. By the time the corn reaches the upper end of the conveyer it will be husked clean and will then be dropped into the wagon. movement is imparted to the axle B by the wheel C, thence to the sprockets D E shaft Rotary E, and the drum F. The exact operation is dependent somewhat on the nature of the soil and the character of the season. Where the soil is heavy or packed, a quick upward jerk on the ear by the fingers F will pull it from the stalk, or if the corn is of suflicient height the ear will be carried against the blade and severed from the stalk. In a sandy loose soil or during an excessively wet season the ear will have a stronger attachment to the stalk than the roots will have to the ground and the stalks will be pulled up by the roots, the fingers drawing the ears to the blade and the latter severing the ears from the stalks, and the stalks will be cast to one side. The sprocket imparts motion to the rollers through sprocket-gears H, H and H and the shaft H and to the sprocket-wheels H of the conveyers and to the rollers through the gear H, shaft H, and gears H H H Having thus fully described our invention, What we claim as new, and desire to secure by Letters Patent, is
