LEICESTER P. KING, OF NEW CASTLE, INDIANA.

CORN-SHELLER.

SPECIFICATION. forming part of Letters Patent No. 237,755, dated February 15, 1881.

Application filed December 11, 1880. (Model) 1'0 all whom it may concern:

Be it known that I, LEICESTER P. KING, a citizen of the United States, residing at New Castle, inthe county of Henry and State of Indiana, 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 same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l is a top-plan view of my invention; and Fig. 2, a side elevation, partly in section.

The present invention has relation to certain new and useful improvements in that class of rotary corn-shellers in which yielding shellerclaws are connected to ahorizontally-rotating gear-wheel, in addition to independent yielding holders for the cob arranged below the shellerclaws, to hold the cob from revolving while bein g operated upon.

The object of the invention is to provide means whereby the tension of the springs connected to the sheller-claws and the holders can be adjusted and regulated at pleasure, in addition to the peculiar construction of the holders and the various parts of the device, whereby a simple, practical, and effective corn-sheller is obtained at a comparatively small cost. These objects I attain by the construction shown in the accompanying drawings, and

- hereinafter described.

In the drawings the frame, which is of cast metal, is composed of two sections, A B, each of which is formed with a leg or support, a. These sections A B have flanges b, by which they are connected together by bolts and nuts 0 d, the sections being also cast with box-sections 0, to form a bearing, when together, for the shaft f of the bevel-gear wheel C, said shaft being provided with the usual crank-handle, D.

The sections A B are cast with grooves 9, so that when the sections are bolted together an annular groove will be secured for holding the circumferential or annular shoulder it upon a horizontal gear-wheel, E, thereby supporting the same and admitting of its rotating horizontally within its groove-bearing by the rotation of the wheel C, the teeth of which engage with the teeth upon the wheel E. The wheel E has arms 1' diametrically opposite each other, to which are pivoted the shanks 7c of the shelling-claws F. The arms tare cast with lugs 1, through which pass the screw-threaded ends of rods m, and through holes in the shanks k, the ends of the rods having thereon screw-nuts n. A coiled spring, 19, passes around the rods m, between the heads thereof and the lugs 1, thereby the tension of the springs 19 being regulated by the adjustment of the nuts it upon the screw-threaded ends of the rods, to adapt the shelling-claws F to the various sizes of ears of corn, or for other purposes.

Jaws G, having a concave fluted surface upon their inner faces, bear. against the cob or car of corn to prevent it turning while the shelling-claws are being revolved. The shanks r of the jaws G are pivoted at their lower ends to lugs s, projecting from the inner sides of the legs or supports a, and below these pivotal points the shanks r terminate in stops t, which rest against the legs or supports and hold the jaws in position when closed, also preventing the springs to from pushing either jaw beyond the center or out of position, which is considered of great importance where yielding cob-holders are employed in this class of corn-shellers.

The lower ends of the springs to are secured to the shanks r of the jaws Gr, their upper ends bein g free, but bearing against set-screws y, said screws regulating the tension of the springs. I

The yielding pressure of the jaws Gr upon the cob or ear of corn is regulated by the tension of the springs to, thereby making every provision for a complete and successfully operating device for shelling corn.

Having now fully described my invention,
