SAMUEL MCQU'ISTON, OF MORRIS, ILLINOIS.

IMPROVEMENT IN CORN-SHELLERS.

Specification forming part of Letters Patent No. 33,442, dated October 8, 1861.

To all whom it incty concern..-

Be it known that I, SAMUEL MoQUIsToN, of Morris, in the county of Grundy and State of Illinois, have invented a new and Improved Corn-Sheller; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in Which Figure 1 represents a sectional side eleva- Fig. 2 is a longitudinal vertical section of the same, taken in the plane indicated by the line a :c, Fig. 3. Fig. 3 is a transverse vertical section of the same, the plane of section being indicated by the line y y, Fig. 2.

Similar letters of reference in the three views indicate corresponding parts.

This invention consists in an improved arrangement of the shelling mechanism, cleaning devices, conveyers, and external casing, having for its object the more perfect separation of corn and cobs without waste of the former.

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

My corn sheller is inclosed in a case A, of wood or any othersuitable material. Its sides form the bearings for the axles a b of the shelling-wheel B and dish-wheels O. The ears are introduced through the chute D, and the bottom of this chute or the feed-board c is set in a position tangential to the dishwheels and radial to the shelling-wheel B, as clearly shown in Fig. 2. By this means each ear as it enters is carried directly over the dish-Wheel into the throat between it and the shelling-wheel, and presented to the latter in a radial position, which is most favorable to effect the rapid rotation of the ear and the instant removal of all the grain.

A machine in which each ear is conducted to the proper spot between the dish-wheels and shelling-wheel at once by the correct position of the chute or feed-board will do onethird more work than a machine of the old construction. An arm t', which is subjected "to the pressure of a spring 7', holds the ears in the proper position While being shelled.

Below the shelling mechanism and about in the center of the case A is the riddle E,

suspended from rods d, and a side shake is conducted to the riddle by inclined boards g,

attached to the sides of the frame A, as clearly shown in Fig. 2 of the drawings. The cobs are discharged over the side of the machine and the corn drops through the riddle on the inclined chutes h, and while passing over these chutes it is exposed to the blast of a fan-blower F. The chaff and other light par ticles which pass through the riddle with the corn are thus blown out on the end of the machine, and the good corn collects in the trough G, from which it is carried up by means of the elevator II to the spout I, through which itis discharged into bags or other suitable receptacles. The trough G and the ele vator II are situated on the side opposite to that on which the cobs are discharged from the riddle E, so that the corn and cobs are completely separated.

13y discharging the cobs in a direction trai'isversely of the wheels I am enabled to dispense with any apertures in the external casing in the plane of rotation of the wheels through'which corn could possibly escape. This arrangement, combined with that of the inclined boards 9 and h, precludes the possibility of'grain being ejected by the centrifugal action of the wheels, thus obviating a serious objection to many of this class of ma chines in common use.

This machine is very simple in its construction, and the working parts are so arranged that they do not easily get out of repair. Each ear is shelled to perfection,

and the cobs and the corn are separated, and the corn is also cleaned and sacked at one operation, so that no further attention is reciined boards 9 g h h, elevator H, and disquired. charging-spout I, arranged and operating in Having thus fully described my invention, the manner and for the purposes set forth. what I claim as new, and desire to secure by Letters Patent, is SAM.
