CORN-SHELLER.

Specification of Letters Patent No. 21,174, dated August 17, 1858i.

To all whom t may concern:

Be it known that I, CALVIN ADAMS, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Corn- Shellers; and I do hereby declare that the following is a full, clear, and eXact description of the construction and operation of the same, reference being had to the accompanying drawings, in which- Figure l, represents a perspective View of said corn sheller; Fig. 2, represents a perspective view of the same, as seen from the reversed side of Fig. l; Fig. 3, represents a longitudinal vertical section through the same; Fig. 4, represents a horizontal cross section through the same; Fig. 5, represents a perspective view of one of the feeding wheels and shafts. i

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, represents a metallic casing, composed of two parts, which are secured together by means of screw bolts and nuts B.

H, and H are two cogged wheels, each of which is formed on one side with a conical hub E, which fits snugly within the conical sleeve I, of the casing A, and thus serves as the bearing for said wheels.

C, and C represent the shafts of the feeding wheels and are furnished near their middle with feeding teeth S, which act against the ears of corn, and feed them through. The shaft C, is formed at one end with four pivots a, which rest within four corresponding holes of the hub E, and can have free play in said holes; the other end V, of said shaft is supported by the end of the hinged arm F, and can play therein freely. The arm F, Fig. l, is hung loosely at one end upon an arm or bracket G, on which it can turn as a fulcrum, while the other end which supports the shaft C, rests against the ends of guard K. The end V, of the shaft C, passes through the slot L, of the casing A, and can play therein freely when the arm F, is vibrated on its fulcrum G.-

K, represents a guard which is intended to prevent any longitudinal motion of the shaft C, when said shaft is rotated and vibrated by the operation of the machine.

N, represents a spring bar one end of which rests on the bracket O, while the other end thereof bears against the projection b, of the arm F.

e, represents a screw nut which is placed between the outer end of the guard K, and the spring bar N, the thumb screw P, passes through this screw nut, and by tightening the same, its vend will bear upon the spring bar N, and will press said spring bar against the projection 5 of the arm F, thereby moving the arm F, and shaft C, in the same direction. The shaft C, is free to assume any oblique position, and still to be revolved by the operation of the machine hy its four pivots a, playing freely within their bearings in the hub E.

Q, Q', represent the shelling wheels of the corn sheller. 'Ihey are formed with a number of arms el, each of which is of a concave or V shape, which strip the grains from the ear as it is fed along. eZ represents cogs which at the Sametime constitute the elongation of the arms al, with this dierence only, that they extend a shorter distance from the center of the shaft than the arms d. By these means, the wheel Q, is in gear with the wheel H, which latter is in gear with the wheel H, which in turn gives motion tothe shaft Q. The shafts C, and C together with their corresponding parts are duplicates and the wheels Q and H are similar to those of Q and H, above described.

W, represents a stationery guide secured to the bolt B; the object of this guide is to direct the ears of corn to the center of the machine, and from the upper to the lower shellers, when they are fed in and carried past the arms (l, of the shelling wheel Q, which is the upper of the two sets.

The operation of the machine is as follows -The ears of corn pass down through the hopper R, of the casing A, and drop with their ends between the feeding teeth S, of the shaft C, and the arms al, of the shelling wheel Q. By turning the crank T, which is fastened to the shaft U, the earsare fed in between and past the feeding wheel and the wheel Q; now if the shaft C, were perfectly rigid it is obvious that the machine could not adapt itself to the different sizes of the ears, but as the shaft C, is yielding and can be pressed against the corn with any desirable pressure, it follows that it can be set so as to eifectually shell the larger or smaller ears, and still render the machine easy to be worked. The corn after having passed between the upper feeding and shelling wheels is guided by the guide W, and passes between the lower feeding and shellceedingly cheap, while it is a very eiicient sheller.

l have described the connection between the shaft C, and hub E, as composed of four studs or pivots and four holes-there may be a greater or less amount-or the end of the shaft may be three or four-sided, and fit into a similarly shaped hole, but of somewhat larger dimensions than itself, so that there may be the necessary toggle or spring yielding mo-tion of the shaft, while it continues to rotate with said hub. The shelling wheels Q, Q run much more rapidly than the feeding wheels C, C and entirely strip the cob before it is fed through,-the difference in velocities may be as three to one.

Having thus fully described the nature of my invention what I claim therein as new 1. The combination of the pairsvof adjustable and yielding wheels C, and C with the pairs of shelling wheels Q, and Q when constructed and operating substantially in the manner and for the purpose described.

2. I also claim the manner of connecting the shafts C, and C with their respective cog wheels H H, by means of the pivots a, a and conical hub E or their equivalents, so that while they Vmay revolve together, the shafts may play back and forth to adapt the feeding wheels to the various sizes of the ears of corn Vto be shelled, substantially as described.

CALVIN ADAMS.
