CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 231,867, dated .August 31, 1880.

Application filed July 1, 1880. (Model.)

To all whom it may concern:

Be it known that I, J AMES W. Tant/TAN, of Manseld, in the county of Richland, State o f Ohio, have invented certain new and useful lmprovements in Oorn-Harvesters; andI do here by declare that the following is a full, clear, and exact description thereof, reference being had to the accoml'ianying drawings, makin ga part of this speciflcation,in which- Io Figure l is a perspective view of my machine from the front. Fig. 2 is a plan view of the upper side of the same, and Fig. 3 lis a cross-section upon line m w of Fig. 2. f

Letters of like name and kind refer to like i 5 parts in each of the figures.

The design of my invention is to enable corn to be husked while standing in the field and without detachin g the husks from the stalks; and to this end it consists, principally, in the 2o peculiar construction of the lnisking-rollers, substantially as and for the purpose hereinafter specified.

It consists, further, in the combination of the husking-rollers and gatherers, substan- 2 5 tially as and for the purpose hereinafter set forth.

In the annexed drawings, A and A represent the side bars of the frame of my machine, which bars are straight in plan view from their 5o rear ends nearly to their frontends, and at the latter points are curved inward, as shown in Fig. 2.

The bars A and A are connected together at or slightly in front of their rear ends by 3 5 means of a cross-bar, B, and at or'near their longitudinal center by means of a bridge-bar, D, while at or near the ends of the latter are provided axle-arms E and E, which receive two ground-wheels, F and F, that furnish a roll- 4o ing support for the machine.

Journaled within suitable bearings formed in or attached to the bridge-bar D and the front inward-curved ends of the side bars, A and A, are two rollers, G and G', which are arranged in parallel lines, with said roller G somewhat higher than said roller G', and with their peripheries but slightly removed from contact. Said rollers are provided with screwthreads g, which have relatively opposite leads,

5o and within said roller G is formed two longitudinal grooves, g', that circumferentially have the form of a saw-tooth.

At their rear ends the rollers G and G' are provided with pinions H and Il, which mesh with each other, while upon the projecting journal of said roller G is secured a bevel-pinion, I, that meshes with a bevel-gear, K, which is secured upon a shaft, L, journalcd in rear of and parallel to the bridge-bar D.

Upon'each end of the shaft L, outside of the 6o side bars, A an'dA, is secured a gear-wheel, M, which meshes with a larger gear-wheel, N, that is secured upon the inner face of each ground-wheel F, by which arrangement the motion of said ground-wheels, as the machine is moved forward, is transmitted to said shaft L, and through the same, the bevel-gear wheel K, and pinions l and H, to the rollers G and G', causing the latter to revolve in opposite directions, their inner peripheries moving 7o downward with uniform velocity.

Secured to and extending in a curve forward and upward from the front end of each side bar, A,is a shoe, O, within the front upper end of which is journaled one end of a shaft, P, the opposite end of which shaft is journaled within a bearing, d, attached to the upper side of the bridge-bar D. rlhe frontends of said shafts P are separated laterally, as shown in Fig. 2, while their rear ends are directly over 8o the rear ends of the `rollers G and G', are provided upon their rear ends with meshing pinions Q, and one of such pinions is arranged to mesh with and receive motion from one of the pinions H.

Secured upon the front end of each shaft l? is one end of a round rod, p, which extends rearward around said shaft in a spiral form that increases regularly in diameter, the rear ends of such spirals being at or slightly in 9o rear of the front ends of the rollers G and G', and having such dimensions at such points as to nearly come into peripheral contact.

Upon the left-hand side of the machine, between the side bar, A, andthe roller G', is an 95 endless apron, R, which atitslower endpasses around a roller, r, that is journaled to the frame at such point, while at its upperend said apron passes around a second roller, S, which is journaled upon the cross-bar B, and Ico is driven by means of a belt, T, that passes around a pulley, s, attached to the journal of said roller S, and around a second pulley, U, attached to the shaft L, the arrangement bcing such as to cause the upper face of said apron to move rearward and upward as the machine is drawn forward.

A second endless apron or carrier, V, is arranged transversely upon the rear end of the main frame, and is supported within a suitable frame, W, that at each end is provided with a roller, w, said frame W being caused to project laterally from one side of said main frame and havingan upward inclination in such direction. Motion is imparted tothe carrier V by means of a belt, X, which passes around a pulley, w, attached to the projecting journal of the outer roller, w, thence laterally to and around two guide-pulleys, Y,

2o journaled upon vertical axes upon the main frame, and lthence forward to and around a pulley, Z, that is secured upon and revolves with the shaft L, such arrangement of parts causing said apron or carrier to have an upward and laterally-outward motion of its upper surface as the machine is drawn forward. From each side bar, A, a short distance in front of the axle-arm E, is secured a bar, A', which extends forward and upward, and furnishes means whereby a horse or a span of horses may be attached to the machine for the purpose of drawing the same, such draft-journals being thus placed where they will travel in the spaces between the rows of corn.

The machine is now complete and operates as follows, viz: When in use the curved bars or shoes 0 rest upon the ground upon each side of a row of corn, and form bearings which support and guide the front end of the machine. When the machine is driven forward each cornstalk of the row being operated upon passes between the spirals p, by which its ears are moved rearward and downward between lthe rollers G and G', which rollers grasp the rier R deposit-s the ears of corn upon the carrier V, by which latter they are carried to and deposited within the box of a wagon or other 4suitable receptacle placed beneath its outer upper end. Where a wagon is employed for the reception of thehusked corn, such wagon may be driven alongside of the husking-machine, the movements of the latter being so regulated as to enable said wagon to travel upon ground from which said machine has removed the corn. The spiral grooves g of the rollers G and G serve to contain the stalks of corn and to pass the same rearward without injury, while the longitudinal grooves g enable the butt -ends of the ears of corn to pass for acertain distance downward between said rollers, when the sloping face of each groove g operates as a cam, and causes a pinching pressure, which looscns the ears of corn from their husks and forcibly ejects the former therefrom without mutilation or other injury to the kernels of corn. In addition to the ofce before described, the spirals operate to gather the fallen cornstalks and raise thc same for the operation of the husking-rollers, and also to regulate and equalize the feed of said stalks to said rollers.

Having thus fully set forth the nature and merits ot' my invention, what I claim as new 1s- 1. rlhe bushing-rollers G and G', provided with spiral grooves g, and one of said rollers having longitudinal grooves g', in combina-- tion with each other'and with means for simultaneously rotating said rollers in opposite directions and for moving the same forward, substantially as and for the purpose specified.

2. The husking-rollers G and G, provided with the spiral grooves g and longitudinal grooves g', andthe shafts I), provided with the spirals p, in combination with each other, and with means for causing said parts to simultaneously revolve, substantially as and for the purpose shown.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

JAS. W. TERMAN.
