CORN-SHELLER.

` SPECIFICATION forming part of Letters PatentNo. 761,068, dated May 31,1904.

' Application filed January 22,1903. Serial No. 140,070. (N o model.)

To all whom, it may concern,.-

the countyof Lasalle and State ofIllinois, have invented certain new and useful Improvements in Oorn-Shellers, of which the following is .av

. specification.

My invention lrelates 'to corn-shellers, and particularly to that class wherein a shellingdrum revolves within a suitable shelling-cylinder.

new and improved deliector located on the cylinder or casing at or near the exit end ofthe machine, whereby the c'obs are positively discharged froin the machine.

` In the accompanying drawings, which form a part of the application, and in which the same reference-letters denote the same or corresponding parts in the various views, Figure 1 is a vertical sectional View of a corn-Sheller with the shelling-drum in side elevation pro# vided with my improvement. Fig. 2 is a vertical cross-sectional view of Fig. l at the exit end of the drum. Fig. 3 is a sectional view on the line 3 3 of Fig. 2, the view beingtaken in the direction of the small arrow. Fig. 4 is a detail perspective of the deflectorof the preceding figures. Fig. 5 is a detail view showing a modification; and Fig. 6 is a horizontal section on the line 6 6 ofFig. 2, showing the inclination of the deector with respect to the shelling-drum, the latter being illustrated ink broken lines.

p any suitable width to allow the chafl` and Be it known that I, JOHN HGILMAN, a citi- .zen of the United States, residing at Ottawa, in

and revolves within the cylinder inthe direction of the large arrows of Figs. l and 2, being driven by any suitable means. The drum is provided with a plurality of rows of shelling-teeth b, arranged spirally along the length vof the drum, as clearly shown in Fig. 1, and at its feed or inlet end with oppositely-disposed curved plates b. Near the rear or outlet end of the drum I prefer to employ oppositely-disposed curved wings 62, the plates and wings acting as shelling elements and being suitably bolted to the drum, so as to present their plainsides or faces to the material in the machine, and being disposed and shaped tobe in extension of the spiral lines of the teeth b.

At the front or feed end of the machine the frame Ais preferably extended upwardly, and the hood O of the casing or cylinder is securedpto this portion of the framework inclosing the feed-aperture and extending overa portion of the drum to form a hopper for feeding the ears into the machine, the sides of this hood being suitably secured at their The upper portion of the casing or shelling-cylinder is in the form of a semicylindrical cover O," which is secured at its front end Vto the roof of the hopper and at its rear end to the frame;

work, being attached at its sides to the'side bars a3; '1 I Y Near the exit or dischargeend of the'rlna# chine and preferably upon thel cover'I locate a suitable deiector D, as'shown in Fig. 6, which is setobliquely at an angle to the axial line of the drum and to form a more or less drum. The deiector is supported on the cylinder near the rear end and in any suitable manner. For example, as shown in Fig. 5, the deector is provided with a flange ci, by

which it is bolted to the cylinder, it beingv understood thatthe flangel is preferably upon the rear side or inoperative face of the delector, or the deliector may be supported by a suitable housing d, which is bolted to the cylinder and receives the deiector. The delector may be made adjustable, as by providing the housing with a slot or guide d2 to receive the deector, which may be moved therein by any suitable means, such `as the hand-wheel d3, which is revolubly mounted and v'supported against displacement on the housing', as by means of the opposite bearings d5 and Z6 or any other suitable means, and has a threaded engagement with the stern d4, which is suitably connected to the lupper portion of the deiiector. In practice the deector may be'formed with an integral upper h ead d?, which enters the guide of the housingv a sufficient distance to have an extended bearing therein,y whereby the delector is securely held against displacement against the Y impact of the cobsas they are swept against it. The housing need not be of the same length asthedeector, in which case ythe delector may project through theend of the housing, as at cls.l By rotating the handwheel in one direction the deflector may be set down to operativeposition, and byy reversing the rotation oi' the wheel it may be withdrawn within the housing, it being apparent that 'its adjustment with relation to the drum vmay be varied and regulated as the occasion requires and that it is securely held in any desired position. When corn is badly husked, the delector is set down nearer to the cylinder than when clean corn is treated, as in the former case the husks chokev the machine at the discharge end unless the dei'lector is employed. It is obvious that the means of adjusting the delector may be. varied without departing from my invention and that the form of the delector may be changed.

In the operation of the machine the ears of corn are fed into the hopper, and as the corn is shelled between the drum and cylinder the cobs are carried by the spiral plates and teeth ltoward the rear of the machine,l the shelled corn dropping through the skeleton bottom of the shelling-cylinder. When the cobs approach the exit of the machine, they are swept and carried bythe teeth .against the deflector, which acts to positivelyfexpel them at the rear. It is obvious that when unhusked corn is treated the husks will be expelled by the deflector in like manner as the cobs. In practical work the cobs have a tendency to clog at the discharge or outlet, whereby the machine becomes quickly choked and obstructed, and the provision of the oblique deflector overcomes this objection, as it obviates all danger of congestion by the cobs by reason ot' the fact that, in conjunction with the spiral projections on the drum, it forms a. chute or channel that gradually is reduced in size as the point where the projections cross the deiiector approaches the rear end, and the cobs are crowded along this channel and positively directed out of the machine. It is obvious that rear wings b2 are of advantage in cooperating with the delector, as their action in carrying the cobs against the dei-:lector is `more certain than that of the teeth, and for this reason I prefer to employ them.

In the construction of the machine it is obvious that the deiiectcr may be set at any angle to the axial line of the drum or to the pitch of the projections thereon.

In practice the shelling of the corn takes place' at all points between the drum and cylinder, and under normal conditions the corn is all shelled oii thecobs before the cobs and husks reach the deflector andrnost ofthe corn has passed through the openings in the lower part vof the cylinder. There are times, however, when the corn is in such condition as to make the shelling of it more diiiicult, and when in this condition aportion of the cobs reach the location or position of the deflector with some corn still on them. When this condition prevails, the deflector is not desired, and it is then kentirely withdrawn into its housing or removed, according to the form employed, to permit the retention of the cobs in the cylinder to complete the shelling operation. The absence of the deiiector greatly reduces the capacity of the machine and is not resorted to except in extreme cases. It is obvious that for. this purpose the deliector of Fig. 5 will be removablyattached to the cylinder.
