IMPROVEMENT IN CORN-SHELLERS The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Be it known that I, ,HAnMon W. CORNELL, of Owego, in the county of Tioga, and State of New York, have invented a new and improved Oorn-Sheller; and I do hereby declare that the following is a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings making part of this specification, in which- Figure 1 is an elevation of the top of the machine, showing the arrangement of its gearing;

Figure 2 is a vertical elevation of the front side;

Figure is a vertical section through the receivingtube; and

Figure 4 is-a transverse section of receiving be, througlrwhich corn passes, the two shelling-cylinders, and spring.

The nature of my invention consists in placing two cylinders, constructed as hereinafter described, paral-. lel to and near each other, both turning in the same direction, but one moving at a greater velocity than the other, and are so arranged that as a springholds ears of corn against both cylinders, the one moving slowest allows them to turn, while the fastest-running cylinder strips off the corn, and also draws the ears through the machine. To enable others skilled in the art to make and use my invention, I will describe its construction and operation.

On a suitable frame is hung a shaft, n, on one end of which is a wheel, A, which has two rows of teeth or cogs, one set of cogs about half the distance from the centre to the outside of the wheel, and the other set at its periphery.

Engaging in each of these series of teeth are small pinions, on the ends of horizontal shafts d It.

Shaft d, which turns with the greatest velocity,

while the machine is in operation, extends across to the opposite side of the machine, where, on the end projecting beyond the frame, is fixed the fiy-wheel G.

On shafts d k, which are parallel to each other, and on the inside of the frame B, are small bevel or mitre-gears c c, fig. 1, which engage in similar gears or "wheels, on two vertical shafts directly under shafts practically covered with spiral hooked teeth.

Thev vertical shafts have each a cylinder, D E, which are parallel and close to each other. One cylinder E is simply corrugated its entire length, while the other c'ylinderD has narrow grooves surrounding it, leaving short elevated portions between them, and these elevations are also corrugated, but the corruga tions are spiral, and the surface of this cylinder is (See figs. 3 and 4.) i"

A receiving-tube, H, formed in a wooden block, F, I conducts ears of corn down between the shafts d and k, to the cylinders, while a spring, 0, inside the tube presses them into the angle formed by the cylinders,

to be'acted upon by both in the process of shelling.

The spring 0 (figs. 3 and 4) does not force corn against both cylinders equally, but is turned (fig. 4)

in such a manner'as to force-the corn hard against the cylinder D, while the motion of this cylinder presses it sufficiently hard against cylinder E.

The spiral teeth on cylinder 1) areinelined in such a direction that they draw ears of corn through the machine, while the length of the cylinders is sure toremove all corn from the cob, and their small diameter,'allowing the work to be done near the centre of motion, greatly lessens the power required to use the machine. I

What I claim as my invention, and desire to secure by Letters Patent, isp 1. The combination of cylinder E, corrugated as described, and cylinder D, constructed with grooves and spiral corrugations, as shown, said cylinders being arranged parallel to one another, and running at dif--' ferent velocities, for the purpose specified.

2. The arrangement of wheel A, shafts n d k, and fly-wheel O,in combination with the corrugated shelling-cylinders D and E, when constructed and arranged in the manner and for the purpose herein specified. HARMON W. CORNELL.
