CORN-SHELLER.

SPECIFICATION forming part of Letters Patent No. 247,173, dated September 20, 1881.

, oted'thereto, as indicated.

My invention relates to that class of handshellers which consist of a revolving annular frame through which the ear is passed, provided with internal teeth to remove the corn,

and contracted at the sides to catch and retain the loose kernels.

The invention consists in various improvements in the details, as hegeinafter described.

Figure 1 is a perspective view of my device in an operative condition. Fig. 2 is a vertical central cross-section of the same. Fig. 3 is a transverse vertical section of the same. Figs. 4 and 5 are detail views.

The device consists, essentially,of an annular body, A, provided with an internal jaw, B, and with a lateral handle, O,by means of which the body is revolved around the ear.

Referring to Figs. 2 and 3,'it will be seen that the body A is of an annular or ring-like form, with a prolongation or extension, 0, on one side to receive the handle 0, whichis piv- The body A is composed, as shown in Figs. 2 and 3, of two substantially equal parts, b and 0, united at the upper end by means of a lip, (1, formed upon one part, and engaging in a recess in the other part, and united at the lower edge by means of a rivet, 6, passed through one of the, parts into a lip upon the other part. also be observed that the two sides of the body are contracted, leaving on each side a circular hole or opening of less diameter than the interior of the body, so that when the ear of corn is passed lengthwise through the body an annular chamber or space will exist therein around the ear to receive the loose corn. This peculiar formation of the body enables the same to catch and retain the corn as it is removed from the ear, preventing the same from being scattered and thrownabout, as commonly happens in the use of the ordinary shellers of this class.

For the purpose of removing the corn from the ear I provide the body A with rigid 0blique blades fat the lower side, and provide the sliding jaw B with corresponding blades or ribs, f.

The jaw B is sustained and guided at its It will.

(ModeL) end by means of vertical rods or pins y, se-

cured to the body by means of lugs h, which are bent downward over their ends, as indicated in Figs. 1, 2, 3, and 4, the rods being inserted and then secured by bending the lips downward around them. The jaw Bis also guided and urged downward by means ofa spiral spring, E, the spring being seated at its lower end around a stem or spindle, c, upon the jaw, and seated at its upper end against the interior of the body A, as shown. The spring is held and guided at its center by means of a lug, k, cast on the interior of the body A. This lugis preferably divided in the center, and bent inward from the two sides in order to clasp around the spring. By thus forming the lug I am enabled to avoid the expense of drilling or coring the device when cast. The spindle upon the jaw is of such length as to extend upward almost to the lug is, when the jaw is in its lowermost position. 1n assembling the parts the spring is applied to and compressed around the stem t of the jaw, the jaw then placed in position and the spring permitted to expand through the lug k and against the top of the body A. When thus applied the spring and the spindle i give each other a mutual support and guidance.

The entire device will be made of malleable cast-iron, brass, or other similar material.

I am aware that wrenches and other devices have had various parts secured to each otherby means of malleable lugs or lips, and this I do not broadly claim. I am not aware, how- 'ever, that any one has hitherto constructed an annular body in the form and manner herein represented.

Having thus described my invention, what I claim is- 1. In a hand corn-sheller, the annular body provided with the lug 7c, in combination with the sliding jaw provided with the short stem 4;, and the spiral spring E, mounted upon said stem and extending beyond the same through the lug k, substantially as shown.

2. In a corn-sheller, the combination of a movable jaw provided with a stem or spindle, and aspiral sprin gmounted upon said stem and extending beyond the same through a guide upon the body, substantially as shown.
