SPECIFICATION forming part of Letters I'atent No. 287,718, dated October 30, 1883.

` Application led May 19, 1883. (No model.)

To aZZwhom it may concern.-

Be it known that I, GEORGE PEIGHAED, a citizen of the United States, residing at Prichardville, in the county of Barry and State of Michigan, havey invented certain new and useful Improvements in Cor11-Shellers5 and I do declarethe following to be aV full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this speciiication. Figure l of the drawingsv is a representation of a top view of the cylinder, the top casing being removed. Fig. 2 is aj vertical longitudinal section of the machine. Fig. 3 is a transverse section of the machine, and Fig. 4 is a detail view.

This invention has-relation to power cornshelling machines; and it consists in the construction and novel arrangement of devices,

as hereinafter set forth, and particularlypointed out inthe appendedclai-in.

In the accompanying drawings, A designates a strong bed-frame provided with the sides B, which are somewhat inclined upward and outward on their inner faces.

C C are the cast ends of the frame, ,tog

which the sides are bolted. The cast ends are formed with seats d, for the journals e of the shellingLcylinder F, and caps g are bolted to said ends, which are made with perforated iiange's h to receive the bolts.

'On ledges or bearings O, at the lower edges of the sides B, is supported the separatorgrating K, which is of elongated form and transversely concave.` This grate or separating-bottom is cast with side bars, Z, and transverse curved bars m, which are of V form in cross-section, so that they will deliver the grain freely in discharging. The side bars, Z, are formed with longitudinal angular faces f, which project somewhat inwardly from the said bars Z of the grating, and serve to assist the action of 'the cylinder in Ytaking the corn from ,the

cobs. The cylinder F consists, mainly, of the circular ends N, which are cast with slots p on j opposite sides of theircentral bearings, near their margins. vThe shaft R passes through the central bearings of these ends or heads, as

shown inthe drawings/ The journal por'- s s indicate semi-cylindrical or partialcyk lindrical plates, which, when tted to each other, form 'the shelling cylinder. These yplates 's are Vformed with externally-projecting studs t, which are preferably of angular form, kfrustumshaped, and somewhat tapering outward from their bases. Each plate s is formed with a tongue, o, at each end,which,`

when the cylinder is put together, enters the corresponding slot, f, in the head of the cylinder, so that when the heads N are keyed on `the shaft the Vplates s will be secured in position. I

H represents the top of the frame or case, which Y`is madeY Vwith sides a .and a top, b, somewhat-inclined downward from the hopper end to the discharging end.

The hopper c projects from the end portion of the top and forms a part thereof, as shown. Within the top are the corner strips or projections, d, which extend full length of and form a part of said top, and are designed to approach thecylinder sufficiently to co-opcrate therewith in rubbing the corn off -the cobs. The front ends of therubbing-ribs d are located just in rear of the sides of the hopper-opening e', and are rounded to facilitate the feeding..

In the rear end wall, g', of the top is made an opening, z, ,through which the cobs arer discharged. Strong hooks h', or other common fastenings, serve to secure the top to the bedf frame.

Having described this invention, what I claim, and desire to secure by Letters Patent, isf Ving the end hopper, c', the rotating shaft R, and the curved cylindriform stud plates s,

connected to said shaft by the end plates, N, slotted at p to receive the ends o of the stud-A plates, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
