ELEVATOR'FOR CORN-SHELLERS. I

SPECIFICATION forming part of Letters Patent No. 355,212, dated December 23, 1886.

Application filed January 29, 1886. Serial No. 190,214. (No model.) I

To all whom it may concern.-

Be it known that I, OYRUs RoBER'rs, of Three Rivers, in the county of St. Joseph and State ofMichigan, have invented new and useful Improvementsin Elevators for Corn-Shellers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a new and useful improvement in elevators for combinedhuskers, shellers, and separators; and the invention consists in the improved construction and arrangement of the mechanism for carrying away to a place of deposit the different products obtained by the separation. The object of the improvement is to enable the operator to carry these products at his will in any desired direction to a place convenientforfilling them in bags or depositing them otherwise, all as more fully hereinafter described and claimed.

In thedrawings which accompany this specification, Figure l is a side elevation of a combined corn, husker, sheller, and separator. Fig. 2 is a cross-section of the tail end of the machine. Fig. 3 is a detached perspective view of the hinged platform upon which the lower end of the cob-carrier is supported. Fig. 4 is a detached perspective of the cob-carrier. Fig. 5 is a detached perspective View of. the cob-spout.

The drawings represent a known type of machine arranged to husk, shell, and separate corn. In this machine A represents the elevator for carrying off the clean corn. B isthe conveyer which carries the corn into the lower end of this elevator, and G is the dischargespout of the elevator. This discharge-spout is made in two sections, the upper one being stationary and connected with the discharge endof the elevator, while thetitower section is movable by being connected to the upper section by means of a universal joint. This joint consists of the hanger D, which is secured to the upper end of the movable section of the discharge-spout, and ispivotally hung from a loose collar, E, which latter is, swiveled onto 50 the lower end of the stationary section of the dischargespout. All these parts are so arranged that the movable section of the discharge-spout may be easily turned by the operator in any direction, so as to deliver the corn to either side of the sheller into a wagon I or to ruin it into gunny sacks, if desired.

G is the cob-carrier, placed at the tail end of the machine to receive the cobs discharged from the machine and carry them to a place of deposit. This cob-carrier is made shifting, so as to deliver the cobs on either side of the sheller, and,when not shelling in husk, to deliver them also in the rear, if desired. To this end the cob-carrier is arranged as follows:

H is a platform, hinged to the tail end of 6 the machine in any convenient'manner, and provided with suitable hangerssuch as the straps Iforsuspending it at different heights above the ground. Upon this platform is journaled in boxes the shaft J, which is pro- 7C vided at the outer end with a chain-wheel, K, and at its inner end with a bevel-pinion, L, which meshes with the bevel-wheel M. This latter revolves on a vertical shaft, 0, secured near the middle oft-he platform,and also serves 7 5 as a pivot for the arm N,which is sleeved upon its lower end, so as to rest on the platform The outer end of the arm N is provided with boxes or bearings P, in which the box R, on the lower end of the couveyer-trough Q, is re.- 3 movably secured, so as to form a pivotal support for said trough. TheboX R forms the bearing for the shaft to which the drive-wheel S of the conveyer-belt T and the bevel-pinion U are secured. 85

In practice the motion for operating the conveyer-belt is applied to the chain-wheel K, and is derived by suitable chain-gearing (not shown) from the machine, and by means of the intermediate connections described it is transo mitted to the wheel 8, over which the conveyer-belt passes and carries the cobs to the discharge end of the cob-carrier. It will be seen that the cob-carrier can readily be shifted in any direction at either side of the sheller, 5 and thefree end of the conveyer-trough can be raised or lowered by supporting it at the desired height, by means of suitable braces, from the ground. All the parts are thus kept out of the way of the flying husks of the corn, which, too as usual in such machines, are blown out at the tail end above the cob-spout.

The advantage of my improved cob-carrier is that its gear for transmitting motion to the conveyer-belt is very simple, and is not liable to be obstructed by any debris which may find its way out of the lower end of the conveyertrough, as the gear is not underneath it, but

- is all placed to one side thereof. Another advantage is that when shelling wet corn, when the wind cannot carry the husks so far, the cob-carrier can be moved to theposition shown in Fig. 2, where it is entirely out of the way of the husks. The adj ustability of the platform H permits of its being raised any distance required above the ground when the machine has to be transported, or for the purpose of keeping it out of the mud.

To prevent the cobs on their way to the cobcarrier from getting choked up in the cobspout, I construct the cob-spout V in a novel manner. Instead of constructing it in the usual form of a hopper with a bottom discharge, I make it more in the form of a V- shaped trough having inclined walls for directing the cobs toward the center and to a discharge-opening, W, formed in the bottom and inclined walls of the spout, through which the cobs can pass out freely in the longitudinal direction of the machine. In this manner the cob-spout forms the tail end.

discharge-opening get choked, the cobs would still be discharged by falling over the tail end of the spout.

What I claim as my invention is- 1. The combination, with the elevator A,

having stationary part 0 of the spout rigid.

therewith, of the loose collar E, swiveled onto the lower end of said part 0, the hanger D, pivotally hung from said collar, and the movable part 0 of the spout secured to and supported by said hanger, substantially as and for the purpose specified.

2. The combination, with' the shoe, of the cobspout forming the tail end thereof, said spout being in the form of a V-shaped trough, the walls of which incline toward the tail end of the machine, and provided with a central discharge-opening through the bottom and said
