HAND CORN-SHELLER.

EPECIFICATION forming part ofLetteqs Patent No. 349,327, dated September 21 1886,

Application filed August 16, 1884.

To all whom it may concern:

Be it known that I, THEOPHILUS \VEAVER, a citizen of the United States, residing at Han risburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Hand Corn-Shellers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. This invention relates to hand corn-shellers, and it has for its object to produce a convenient and improved sheller whereby the corn is shelled from the cob; and to this end the invention consists in the novel construction and arrangement of devices, as will behereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents an edge view of my sheller. Fig. 2 represents a side elevation of the same with the front section of easing and the handle removed. Figs. 3, 4, and 5 represent, respectively, the movable shelling-j aw, the stati on ary shelling-j aw, and the handle-shaft.

'In the description and drawings like letters denote like parts in the several figures.

The letters P and Q denote the sections of the casing, the former of which is the front part of the casing, having in its enlarged annular por tion an opening, a, into which the ears of corn are presented to the shellingjaws. The other section, Q, is the rear part of the casing, having in its annular portion the opening a, which is the outlet for the cobs from said jaws, and both of said sections are secured together by bolts or rivets, as shown at L and t.

The letters R R denote correspomling tubular abutments on the annular portions of said sections of the'casing, which form the socket R, in which is located the outer end of the spiral spring M. The inner end of this spring is sup ported on a short stud, (l, on the movable jaw D, as hereinafter more fully described. The outer ends, S S, of said abutments are come spondingly recessed in their meetin g faces, forming, when united, a cutaway spherical socket, S in which is loosely swiveled the ball K on the inner end of the handle-shaft K, which carries the op eratinghandle H, which is j ournaled loosely on said shaft in a manner to allow it to Serial No. 140,733. No model.)

revolve. Even if perch ance said handle becomes stuck on said shaft, the shaft itself may revolve axially. The ends S S are provided with coinciding transverse slots WV, forming a way for guiding therein the shank K of said shaft, 'it being adapted to be swung therein for reversing the position of the handle H. The ends of said way serve as stops for said reversing movement, causing said handle, when stopped, to stand at right angles to the plane of the parting-line of the casing-sections P Q. The handle H will stand right for rotating the sheller when it is taking in the point of an ear of corn, and may be adjusted to reversed position when the sheller is reversed, for shelling the last part of the car, without taking the hand off the handle. The handle-shaft proper or stem, K, is illtegral with the parts K K so that it may not work loose. The shank K serves to add strength to said shaft at a point where it is most needed to resist bending.

The stationary jaw G is distinct from the casing, and has parts a a, adapted to take hold in abutments on the casing-sections at four nearly equidistant points, and said parts are kept in place by the said sections when secured together. It is more expedient to make some of said part-s, as parts a, in the form of pins, so as to set in holes,and to make others of said parts, as parts a, in the form of lugs, so as to simply fill the space between two corresponding abutments,in order that accuracy may not be required to fit said parts to their bearings. v

Outhe jaw C are the parallel arms or extensions A A, which act as guides for regulating the movement of the movable jaw D located behind them. The shelling-lips B B on the jaw 0 present their inner edges nearly in line with the circle of the exit-opening X in the casingsection Q, thus assisting to steady the implement in its rotary movement. The movable jaw D has on it the shelling-lipsE E, between which and said lips B B is the opening or throat. The parts 6 e of the movable jaw are slides, to ride laterally :against the guides A A on the stationary j aw, and the portions G G of the movable jaw serve as bearings upon the guidesA A to keep said jaw applied to the parallel guides A A. Said jaw isprovided with a short stud, d, as the support for the inner end of the spiral spring M. Between said spring and the outer support, R, and its inner support, 11, a space intervenes, which is occupied only by the unsupported middle portion of said sprin Through the opening an in casing-section I the spring is readily applied to the socket R and the Stud 01, and can be easily removed therefrom through said openin The object of this arrangement and construction of the openingis, that said spring may be replaced by another when worn out or broken withoutundoing the the rivets or bolts which join the casing-sections together, and that the work of fitting up the machine may be facilitated, as the parts can be more easily held in place by riveting before the spring is inserted. Distinct from said spring-support d on said jawis the arm or extension D, arranged parallel with and outside of the socket R, having its hearings in notched places I) in the casing-sections. On said arm is the lateral projection D, so an ranged that the operator with one hand can operate handle H and said projection simultaneously, and thereby retract said movable jaw, and thus enlarge the opening or throat between the shelling-jaws,so that blunt ears may be more readily started into the implement. On the peripheries of the annular portions of the casing-sections are notched places, at Q Q Q Q, constituting apertures, at which detached grains may drop out as the sheller is rotated. At the parting-line of the casingsections one of them has on it a projection adapted to enter a recess in the other section, whereby the rivets or bolts L t are assisted to resist lateral strain tending to displace said sections from their superimposed position.

I claim 1. In a hand corn-sheller, the casing-sections provided with extensions having on their meeting faces corresponding recesses constituting a cut-away spherical socket,and having in the shell of said socket a transverse way, in combination with an operating-handle and a shaft having a ball on its inner end loosely swiveled in said socket, and a shank between said ball and handle adapted to swing in said way for guiding and sustaining said handle, substantially as set forth.

2. In a hand corn-sheller, the combination, with the easing-sections having recessed abutments which form the tubular socket R, of a stationary shelling-jaw having parallel extensions which are supported in bearings at the parting-line of said sect-ions, a movable shellk ing-jaw having extensions which are guided against and by said parallel extensions, and also having a short stud axially in line with said socket, and a spiral spring with one end inserted in said socket and its opposite end applied to said stud, as and for the purpose set forth.

3. In a corn-sheller, the combination of the casing provided with the recessed or tubular extensions It It, forming the socket R, and the stationary and movable jaws, the latter having a short stud, d, thereon, with a spiral spring, M, having its inner end supported by said stud and its outerend fitted in said sockct, the construction and arrangement of the parts being such that said spring can be removed and replaced without removing other parts, substantially as described, and for the purpose set forth.

4. In a hand corn-sheller, a stationary jaw having shelling-lips, in combination with a movable jaw having shelling-lips forming a throat between them for admitting ears of various sizes, said movable jaw having arm I) thereon, provided with projection D, the easing-seetions, and an operatirig-handle, H, substantially as set forth.

5. Ina hand corn-sheller, the combination of the casing-sections I Q, secured together and formed with socket R, and provided with the operating-handle H,with a stationaryjaw provided with parallel guides A A, the movable jaw having parts adapted to ride against said parallel guides, and the removable spring M, having its outer end in socket It and its inner end supported on the movable jaw, substantially as and for the purposes set forth.
