Letters Patent No. 70,195, elated October 29, 1867.

IMPROVED UORN-SEELIIER.

TO ALL WHOM 1T MAY GONCERN:

Be it known that I, GEORGE GOEWEY, of the city of Philadelphia, Sta-te of Pennsylvania, have invented a new and useful Machine for Shelling Corn; and I do hereby declare that the following is a fulland exact description of-the construction and operation of the same, reference being had to the annexed drawings, forming part hereof, in which drawings- Figure 1 is a perspective view of the machine.

Figure 2, a transverse vertical section thereof on the line my of' fig. 1.

Figure 3,V a perspective of the corrugated cylinder detached.

vFigurefl, a similar view of three of the sections of the shell or concave detached; and

Figure 5, an end view of thcsame showing the springs.

Referring to the drawings, a, fig. 1, is the frame of the machine, which is formed of wood or iron. Z1, gs. 2 and 3, is a cylinder covered in at top, `as shown in flg. 2. e, figs. 2, 4, and 5, is the shell or concave, which is formed in separate sections, as shown, `and consists of a number of toothed parallel bars set diagonally, forming with the rim of theconcave an' angle of about forty-tive degrees. The parts marked d are springs; they are applied to each end of the concave. e, fig. 1, is a cogged wheel that turns upon a fulcrunbpin attached to the frame of the machine. Wheel egears into a smaller cog-wheel,f, on the end bf the cylinder-journal. g is a ily-wheel on the cylinder-journal; it is faced off so that it can be used with a belt as a pulley when it is 'desired to use power other than hand-power, the. wheel e in such case being either retained or removed, as

desired. h 7i' are two guide-boards, which slide in grooves formed in the fra-me of the machine. The cylinder In may be made of wood or iron, `solid or hollow. It is belted with parallel corrugations or ribs t', which are crossed by the longitudinal flanges c. The ribs are about three-fourths of au inch apart at their bases. They are about three-eighths of an inch in the cross-section at their bases, about three-sixteenths of an inch at their edges, and about one-half an inch in depth. The flanges k project about one inch beyond the ribs z',- they are about half au inch thick at their bases, tapering to three-sixteenths of an inch at their outer edges, which edges show a rounded surface. The angcs are about three inches apart, measuring between their bases. If the body of` the cylinder is of wood, the ribs t' and flanges c must be of iron fastened to the wood. substantially. The ribs and `ianges may'be cast together. The concave consists of several sections, the number of which equals lone-half the number of spaces between the flanges k. They extend from one end to the other end of the machine, and each section corresponds in width with the distance between the outer edges of flanges c. The extreme height of frame of the machine is about three feet,lwidth about twenty-three inches, length of cylinder about sixteen inches, diameter of cylinder abouteight inches, or including ribs and flanges about, nine and a half inches. The throat of the hopper m is of suilicient size to freely admit the ears of corn one at a time into the shelling-spaces of the cylinder. i Y

After the machine is put in motion the ears of corn are thrown into the hopper or opening m, and they fall upon the ribs z', one car at a time into each space between the ilangesA lc, which langesfimpel the ears forward and compel them to revolve. The shelled corn drops through the concave, and the cobs pass out through the opening on the side of the machine opposite the hopper. Each section of the concave acts independently, and thus allows several ears of corn to be shelled at the same time without interfering one with the others Having thus described my invention, I claim, and desire to secure by Letters Patent-- 1. 'The ribs z' for the purpose of enabling the ears of corn while being shelled to revolve freely and not clog.

2. The longitudinal flanges k for the purpose of compelling the ears of corn to revolve and prevent their getting crosswise in the machine while being shelled.

3. The concave c formed in sections with diagonal toothed bars, each section actingindependently of the other sections, and corresponding in width with thespaces between any two of the longitudinalhanges k at their outer edges, substantially as set forth.

4. The combination of the cylinder li. concave @and springs d, in the-manner and for the purpose substantially as set forth. I i
