To all whom it may concern.-

Be it known that I, GEORGE MEADER, a citizen of the United States, residing at Fowler, in the county of Benton and State of Indiana, have invented certain new and useful Improvements in Corn-Huskers; 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.

This invention relates to corn-huskers, and one of the objects of the same is to simplify the mechanism in machines of this character and to economize in weight and cost of manufacture.

' Another object is to improve the construction of the gathering, snapping, and cleaning rollers in machines of this character.

Still another object is to provide means whereby the elevator may be swung to the side of the machine or to the rear end thereof and the discharge end raised or lowered to the required height to discharge into wagon-boxes of varying heights.

These and other objects are attained by means of the construction illustrated in the accompanying drawings, in which Figure 1 is a side view of a corn-husker embodying my improvements, the draft-tongue being broken away and the adjusting-lever being removed to better show the construction. Fig. 2 is a plan view of the same, the guideboards at the rear end of the frame being removed to better illustrate certain details. Fig. 3 is a rear end elevation of the machine and showing the elevator and means for adjusting it. Fig. 4 is a detail elevation of a lever and rack for adjusting the inclination ofthe frame of the machine relatively to the draft-tongue. Fig. 5 is a detail plan of one of the gatheringrollers and the universaljoint connection thereof. Fig. 6 is a plan view of the snapping and cleaning rollers detached from the machine.

Referring to the drawings by numeral for a more particular description of my invention, the numeral 1 denotes a suitable frame of general rectangular shape and of box-like construction mounted upon wheels 2 and 3, the wheel 2 serving as a drive-wheel for the rollers and the endless carrier of the elevator. nected to one corner of the front portion of the frame 1 is a draft-tongue 4, pivoted to a bracket 5 and provided with a brace 6, piv- Gonoted at 7, and a brace 8, one end of which is pivoted at 9 to the draft-tongue and its opposite end connected pivotally at 10 to an ad justing-lever 11. The lever 11 is pivoted at 12 to the side of the frame of the machine and is provided with a sector-rack 13 and a springprojected locking-rod 14 to engage the notches 15 in the sector-rack 13, as is clearly shown in Fig. 4.

The gathering-rollers 16 each consist of a i central shaft 17 and a spirally-arranged screw 18, the front end of the shaft 17 being journaled in a bracket which extends outward and downward from the shaft and is connected at its rear end to the frame portion of the machine.

Upon reference to Fig. 2 of the drawings it will be seen that the gathering-screws diverge at their outer ends. the inner ends of the shafts 17 being connected by universal joints 19 or suitable flexible connections to shafts 20, j on rnaled in brackets 21, secured to plates 22, spaced apart to forma passage for the stalks.

The shafts 20 at their upper ends are connected to the combined snapping and cleaning rollers 23 24, with which they revolve. The rollers 23 24 are provided with conical front ends 25, at the rear of which the rollers are provided with right and left hand spirallyarranged ribs 26. It will be noted that the ribs 26 at the front end of the rollers 23 24 are intermediately disposed one to the other, while at the rear portion said ribs are substantially parallel or oppositely arranged, as shown. At the termination of the rib portion of the rollers 23 24 said rollers are slightly enlarged in order that the rib portions of said rollers may set at the required distance apart to perform their function, while the enlarged rear ends of said rollers which form the cleaning or stripping rollers may be substantially in contact. The cleaning portions of the rollers 23 24 are grooved spirally toward the rear, the grooves 27 28 being oppositely arranged in order that they may register when oppositely rotated. Wound within the groove 27 of roller 23 is a rope or-cable 29, which fills the groove and extends beyond the periphery of the roller to engage the groove 28 in roller 24. Instead of arope or cable, as 29, I may use rawhide, barbed wire, or other materials, depending upon the character of work to be done and the condition of the field. At their rear ends the rollers 23 24 are provided with gear-wheels 30, and the rear ends of the shafts 20 are journaled in brackets or standards 31, secured at their lower ends to the frame 1 of the machine. A guard-plate oserves to prevent the corn from being caught between the gear-wheels 30. The shaft 20 of roller 24 carries at its rear end a beveled gearwheel 32, which meshes with a similar gear 33, fixed to ashaft 34, provided with asprocketwheel 35, connected by a chain 36 to a sprocketwheel 37 on the axle of the drive-wheel 2.

An endless belt 38, carrying fingers or flights 39, serves to carry the stalks upward from the rear ends of the gatherers between the rollers 23 24; The belt or chain 38 at its front end passes around an idler or sprocket 40 and at its rear end is carried by a sprocket-wheel 41, mounted upon a vertical shaft 42, having a bevel-gear 43 secured thereto, as shown in Fig. 3, said gear 43 being in mesh with a gear 44, mounted on the end of a stub-shaft 45, journaled in brackets on the frame and provided with a gear-wheel 46, which meshes with gear 30 on the rear end of roller 24.

The elevator comprises a chute 47 in which is mounted an endless belt or chain 48, carrying fingers or flights 49, said belt or chain passing over an idle sprocket 50 at one end and at the opposite end over the sprocketwheel 51, connected to a shaft 52, provided with a universal joint 53, connected to the lower end of shaft 42, said shaft being journaled in a bracket 54, secured to a cross-bar on the frame of the machine. The chute 47 is pivoted at 56 to swing laterally froma position at the side of the frame, as shown in Fig. 3, to a position extending outward at the rear of the machine, and the discharge end 57 of the chute may be raised or lowered to accommodate receivers or boxes of varying heights by means of a rod or bar 58, secured to the under side of the chute 47 and extending into a tubular keeper 59, provided with a bind ing-screw to hold the rod 58 in adjusted position. The keeper 59 is formed on or secured to a bar 61, mounted to swing upon the pivotal point 56.

Guide-boards 62 are supported upon suitable brackets 63 above the rear ends of the rollers 23 24, and the fingers 39 on the chain 38 assist in carrying the corn over the gearwheels 30 to discharge it upon the inclined board 63 and into the chute 47, whereby it is conveyed to the discharge end by means of the fingers or flights 49.

The operation of my machine may be described as follows: The machine is drawn by horses attached to the pole or tongue 4, a row of corn passing between the gatherers 16, which run near the ground to pick up the down corn and convey the stalks between the plates 22 to a position to be carried backward between fingers 39 on the chain 38 to the snapping-rollers 23 24 and backward between the cleaning-sections of the rollers 23 24, the

stalks and husks being carried downward to the ground and the cleaned ears passing backward to the rear end of the rollers 23 24, where they are discharged into the chute 47 and conveyed between the fingers 49 to the discharge 57 of said chute and dropped into a wagon attached by its tongue to the machine in position immediately over the discharge portion of the chute. If the elevator is arranged, as shown in Fig. 3, to discharge at the side of the machine, I may provide a box or receiver into which the corn may be discharged, and this box or receiver may be discharged into a wagon when filled. To tilt the frame upward at the rear, the lever 11 is operated and locked to the sector 13 in adjusted position.

From the foregoing it will be observed that the machine is comparatively simple in construction and is light and easy of draft, that the combined snapping and cleaning rollers are reliable and efficient for the purpose, and that the discharge-elevator may be adjusted to suit varying conditions of service.

Various changes in the shape, proportions, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this in- Vention.

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

1. In a corn-husker, oppositely-disposed spiral gatherers in combination with combined snapping and cleaning rollers provided with spirally-disposed ribs on their forward portions, spirally disposed and oppositely arranged grooves upon the rear portions of said rollers, the grooves in one of said rollers being wound with material to extend into the groove in the other roller, substantially as described.

2. A combined snapping and cleaning roller comprising a spirally-ribbed front section and a spirally-grooved rear section, the grooves in said rear section being wound with a material adapted to project beyond the periphery of the roller, substantially as described.

3. In a corn-husker, a pair of snapping and cleaning rollers comprising spirally-ribbed front sections, said ribs being intermediately disposed upon the rollers at their front portions and arranged to register at their rear portions, spirally-disposed grooves in the rear portions of said rollers, the grooves in one of said rollers being wound or filled with a material adapted to strip the corn-husks from corn, said material extending into the grooves of the other roller, substantially as described.

4. In a corn-husker, gatherer-screws having opposite spirally-arranged"body portions mounted upon shafts journaled at their front ends in diverging brackets, universal joints connecting the rear ends of said shafts with the shafts upon the front of the snapping and cleaning rollers in combination with the snapping and cleaning rollers comprising spirallyribbed front sections, spirallygrooved rear sections, the grooves in one of said rollers being filled by a rope or cable Wound Within the grooves and extending beyond the periphery of the roller to engage the groove in the other roller, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
