CORN-SHELLER.

SPECIFICATION forming part of Letters Patent N o. 484,474,'dated October 18, 1892.

Application filed March 26, 1892. Serial No. 426,514. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL STROUP, a citizen of the United States, residing at Elmwood, in the county of Cass and State of Nebraska, have invented certain new and useful Improvements in Corn-Shellers; and I do declare the following to be a full, clear, and exact dedescriptionof the invention, such as will enable others skilled in the art to which it appertains to'make and use the same.

This invention relates to improvements in corn-shellers of that class which employ a cylinder and a concave adapted to'dis'charge the cobs and to means for stacking the same at one end of the machine; and, among'other things, the invention has for its object, first, to provide an improved shelling mechanism in which the cylinder acts with great power against the corn-ears and serves, also, to feed the same quickly away from the receivinghopper secondly, to provide an improved contrivance for automatically feeding the ears directly from the crib to the primary hopper without constant attention on the part of the operator, and, finally, to so arrange the shoe {and cob-stacking mechanism thatthe dust and chaff are blown from one end of the machine, relieving the attendants from annoyance from the flying dust and chaff, while the cobs are discharged from the other end of the machine into the stacking mechanism. I

' With these and other ends in view the invention consists in the novel combinations of devices and peculiar construction and arrangement of parts, as will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation showing the machine in a condition for use. same. Fig. 3 is a longitudinal sectional view through the machine, showing the shelling cylinder in side elevation. Fig. 4 is a detached detail view of the crane for supporting the feeder-trough, which is shown partly broken away. Fig. 5 is a top plan view; and Fig. 6 is a transverse section taken in the plane indicated by the line a: :r of Fig. 1, looking in the direction of the arrow.

Like numerals of reference denote corresponding parts in the several figures of the drawings.

Fig. 2 is an end view of the This machine belongs to that class of cornshellers which are designed to be moved from one'place to another, and it is mounted on suitable wheeled tracks (not shown) for this purpose.

The main frame 1 of the machine has a primary hopper 2 in its upper front part, and longitudinally of the main frame is arranged the horizontal shelling-cylinder 3, which has its shaft or trunnions 4 4' journaled in suitable bearings at opposite ends of the main frame. The outer end of the shaft at the front of the machine is provided with a bevelgear 5,wh'ich meshes with a similar gear 6 on a'horizontal transverse shaft 7, which is suitably journaled in the frame 1, and to which shaft power is communicated byabelt 8, running around a pulley 9, or by any other convenient means.

Beneath the cylinder and extending longitudinally of the same is a concave 10, and the arrangement of said concave and the teeth on the front part of the cylinder are such that a quick feed of the corn-ears from the hopper is possible. The teeth 11 at the front part of the cylinder are made FF-shaped and arranged in two or more spiral series around said cylinder to effect the quick feeding of the corn-ears between the cylinder and concave, while the remaining teeth of the cylinder are the same as the ordinary teeth of corn-shellers. The cylinder is covered by a stout sheet-metal jacket 12, which extends from the hopper to the rear end of the machine, and the corn-cobs after the grains have been removed therefrom are discharged into a cob-receptacle 13, suitably fixed to the rear end of the frame to receive the cobs from the cylinder. This receptacle has a screen 14, onto which are discharged any grains that may be carried with the cobs to the rear end of the machine, and the grains from said screen are deposited upon a conveyor 15, operating in a trough 16, (see the dotted lines in Fig. 1,) said conveyer discharging into the hopper 2 at the front of the machine and being driven by a shaft 17, having a belt connection 18 with the fan-shaft, as shown by dotted lines in Fig. 1. The cobs are discharged from the receptacle 13 into a hopper 19 of the cob-stacker 20, which is arranged in an inclined position beyond the rear end of ICO the machine and with its hopper 19below the receptacle 13, so as to receive the cobs directly from the same. In this cob-stacker operates a conveyor, which is driven from a shaft 21, belted to a counter-shaft 22, which in turn is driven by suitable connections with the fanshaft presently referred to. The grains removed from the corn-ears by thecylinder and concave are precipitated upon the riddles of a shoe 25, which is suspended by links 26 below the cylinder and which extends longitudinally of the machine from the front to roar thereof. This shoe has the inclined end board 27 arranged in front of the fan or blower 28, which has its shaft 29 driven by a belt 30 directly from the transverse power-shaft of the machine, and this fan sends a blast or current of air from the rear end of the machine toward the front end thereof, so that the chaff and dust are blown out at the front end of the machine and the corn-cobs are discharged at the rear end thereof.

At the front end of the machine, below the primary hopper 2 and the receiving end of the shelling-cylinder, is arranged an inclined grain-board 31,. which directs the grains of corn onto the riddles of the shoe. This shoe is given an endwise shake by means of a cam 32 on a rotary transverse shaft 33, which is suitably journaled in the main frame 1, and

- is driven from the power-shaft 7 by chaingearing consisting of sprocket-wheels on the shafts 7 33 and an intermediate chain. (See Fig. 2.) Around the cam 32 fits a yoke 34,

which is connected by an arm 35 to the suspended shoe. (See Fig. 3.) The shoe discharges the grain to a transverse horizontal receptacle 36, arranged below the shoe, and in this receptacle operates a worm or screw conveyor 37, which delivers to an inclined elevator 38. This elevator is arranged on the outside of the machine, as is usual, and at its upper end it has a swinging mouth 39, adapted to be adjusted to discharge into the hopper 2, so that if the grain is not cleaned satisfactorily on its first passage through the shoe the same can be carried to the hopper 2, so that it can pass to the grain-board 31 and be again subjected to the cleaning action of the shoe.

The front end of the machine is left open for the escape of the dust and chaff blown from the riddles of the shoe by the fan, and this open end is adapted to be closed when the machineis not in use byahingod board40. In use this board is raised and is sustained in place by the swinging supports or leaves 41, which are hinged to the main frame so as to turn horizontally, while the board 40 is hinged to swing vertically. When the board 40 is raised, the leaves are turned outwardly beneath the board, so as to sustain the same in its elevated position,and to lower the board the leaves are turned inward toward each other and theboard 40 drops down and conceals the leaves from view.

I provide novel means for supplying or feeding the ears of corn directly from a crib to the receiving-hopper 2 and only require one attendant instead of the two attendants, which are usually necessary with ordinary corn -shellers. This feeder consists, essentially, of a trough 45, which is pivotally connected at its upper end on a short shaft 46. This shaft is journalel in'suitablo hearings on a horizontally-swinging crane 47, having vertical trunnions, which are stopped or pivoted in suitable hearings on the side of the main frame. This crane is pivoted on the machine, so that the feeder can be swung alongside of the main frame, as indicated by dotted lines in Fig. 2, when the machine is to be moved from one place to another; but when the machine is in use the crane is swung around, as in Figs. 1 and 2, so that the upper end of the feeder-trough is immediately over the hopper 2 and the feeder extends outwardly from the frame. (See Fig. 2.)

In the feeder-trough is arranged an endless couveyor 48, which is operated by means of the short shaft 46, and at one end this shaft is provided with a bevel-gear 50, which when the crane is adjusted to bring the feeder into operative position meshes with a similar gear 51 on a counter-shaft 52, which that the conveyor of the feeder is operated from the counter-shaft and power-shaft. As the feeder-trough is pivotally connected to the shaft 46, the feeder can be raised or lowered to accommodate the corn-crib, and when adjusted in position, so that its shaft 46 is driven from the shaft7, a single attendant is only required to remove the corn-ears to the hopper of the feeder, from whence the ears are carried to the hopper 2.

The operation of my invention will be readily understood by those skilled in the art from the foregoing description, taken in connection with the drawings.

Having described my invention, what I claim is 1. In a corn-shelling machine, the combination, with the main frame having the hoppers, the shaft 52, and the beveled gear 51, of the swinging crane pivotally connected to the main frame, the feeder-trough 45, carried by the crane, the shaft 46, journaled in the upper end of the feeder-trough, the endless conveyor 48, arranged in the trough, taking around the shaft 46, and the beveled gear 50, fixed upon theshaft 46 and adapted to engage the gear 51 when the feeder-trough is swung into a position at right angles to the main frame, substantially as specified.

2. In a corn-sheller, substantially as specified, the combination of a main frame, a hopper, the longitudinal cylinder, the concave, the cob-receptacle at the rear end of the frame, having the screen 14 and a lateral spout, and .the endless conveyor traveling beneath the mouth of the spout and adapted to receive the grain from the screen 14 and. discharge the is driven by gear from the main shaft 7, so

same in the hopper, substantiallyv as and for the purpose set forth.

3. A corn-sheller, as described, comprising the following instrumentalities, in combination, viz: a main frame, a hopper, a longitudinally-arranged shelling-cylinder, the concave, the cob-receptacle at the rear end of the frame, having the screen 14, the endless cobstaoker adapted to receive the cobs from the cob-receptacle, the endless conveyer adapted to receive the grains from the screen 14 and discharge the same in the hopper, the shoe arranged beneath the concave, the fan arranged in rear of the shoe, the transverseconveyer arranged in advance of the fan, and the endless elevator adapted to receive the grain from the transverse eonveyer, all as and for the purpose specified.

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