CORN-SHELLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 236,894, dated January 25, 1881.

Application filed May 27, 1880. (No model.)

To all whom it may concern Be it known that I, FRANCIS M. KENT, of Grand Ledge, Eaton county, Michigan, have invented an Improvement in Corn-shelling Machines, of which the following is a specication.

The nature of this invention relates to certain new and useful improvements in the construction of machines designed for shelling corn; and the invention consists, first, in the peculiar construction of the shelling-jacket; and, second, in the peculiar construction, arrangement, and combinations of the various parts, all as more fully hereinafter set forth.

Figure 1 is a perspective view. Fig. 2 is a vertical section through elevator. Fig. 3 is a vertical longitudinalv section. Fig. 4 is a vertical section through the hopper. Fig. 5 is a detached perspective of one of the sections or staves of the jacket. Fig. 6 is a cross-section of the same.

In the accompanying drawings, which form a part of this specification, A represents a suitable frame, to the top of which is journaled the main shaft B, upon which is secured the conical cylinder C, in the periphery of which are secured the ribs a. and teeth or studs b. A hopper, D, the bottom of which terminates in a perforated jacket, D', incloses the ribbed end of the cylinder C, the inner end of said jacket and hopper being formed in a ring or ange, E.

At the larger end of the cylinder is secured in the frame a iianged ring, F, and between these two rings surrounding the cylinder is formed a shellingjacket, G, which is constructed as follows: c are sections or staves, provided with indentations d upon both edges sufficiently large for the passage of kernels of corn, but too small for the passage of cobs, and plates g, which latter are placed in proper openings in the rings E and F, there being a sufficient number used to entirely surround the cylinder, thus forming the shelling cage or cylinder. These staves and the inner face of the jacket D are provided with longitudinal ribs o o. At the discharge end of the jacket there are interposed between the ends of the staves c and the flange of the ring F suitable springs, h. This construction of the 5o shelling-cage allows the staves to adj ust themselves independently to the various sizes of ears, and to give77 in case any hard substance should accidentally get into the machine.

Below the shelling cage or jacket G D is suspended, by proper hangers, a screen, H, below which is secured a bottom board and collecting-chamber, I. A short shaft, J, is journaled in the frame, carrying upon one end a disk and wrist-pin, t', which is connected to the screen-frame by a shaker-rod, p. The opposite end of this shaft J has secured to it a' bevel-wheel, j, which meshes with a similar wheel, 7s, which is driven by means of a belt from the main shaft on the pulley m, this mechanism being designed to impart a longitudinal shaking movement of the screen.

The collecting-chamber is provided with a spout, n, which delivers the corn to the elevator K, which discharges the corn into any desired receptacle, while a fan in the case L draws all light particles of cob, dust, Ste., up through the duct M and discharges the same outside the machine.

N represents a cover to inclose the shelling- 75 cage.

Corn in the ear, being fed into hopper, falls upon the cylind er, which, in its rotation,knocks 0E the kernels of corn, which fall through the cage and screen into the collecting-chamber, while the cobs pass out of the cage and oft' at the end of the screen.

I am aware that a shelling-jacket composed of separate staves surrounding the shellingcylinder, each stave being hinged at its upper end to the frame of the sheller, and having a coiled spring interposed between its lower end and the frame of the sheller to allow the staves to adjust themselves to the various sizes of ears, has heretofore been employed; and I therefore lay no claim, broadly, to such construction, my invention being confined to the details of construction of my shelling-jacket, as pointed out in the claims.

What I claim as my invention is- 1. The combination, with the shelling-staves c, each having indentations d on both its 1ongitudinal edges, plates g on its ends, and a rib, o, on its inner face, of the cylinder (j, proas described, slotted rings E F, and springs h, vided with studs b, slotted anged rin g F, substantially as described, and for the pur 1o slotted ring E, and springs h, substantially as pose sei; forth. described, and for the purpose set forth.

5 2. The combination, With the conicallyshaped cylinder C, provided with studs b and Witnesses: ribs a, ofthe hopper 1), perforated jacket D', GEO. B. BROWN, having ribs o', shelling-jacket G, constructed J. L. MCPEEK.
