CHARLES IVIACHACEK, JR., OF TABOR, SOUTH DAKOTA.

CORN-SHELLER.

To all whom it may concern:

Be it known that I, CHARLES MACrracnK, Jr., citizen of the United States, residing at Tabor, in the county of Yankton and State of South Dakota, have invented certain new and useful Improvements in Corn- Shellers, of which the following is a speciiication.

This invention relates to corn shellers, and has for its object to provide a simple and an effective means for preventing the cobs from returning along the elevator of the sheller when they have arrived at the delivery end thereof. By such an arrangement much of the annoyance usually found in corn shellers is avoided for the reason that it frequently happens that cobs will return along the under run of the conveyer belt of the elevator and will enter the buckets of the grain elevator and choke the same, or injure them by becoming wedged between the buckets and fixed parts of the machine.

In carrying out the invention, I provide fingers of peculiar configuration which are adjustably located at the delivery end of t-he cob elevator trunk and which have portions that extend up under the rotating members that carry the chain belts and eX- tremities curved in a downward direction from the said upcurved portions and eX- tending away from the elevator belts.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which:

Figure 1 is a longitudinal sectional view of a corn sheller with the improved attachment applied; Fig. 2 is an enlarged detail sectional view through the attachment; Fig. 3 is a perspective view of the attachment.

Corresponding and like parts are referred to in the following description and Vindicated in all the views of the accompanying drawings by the same reference characters.

To better understand the invention it is illustrated applied to a corn sheller indicated at l which is provided with an elevator trunk 2 along which chain belts 3 are Specification of Letters Patent.

mounted for movement. At the upper end of the trunk 2 the belts 3 pass around disks or wheels It which are mounted upon a driven shaft 5, any suitable means being provided for driving the said shaft. A cross bar 6 is located at the upper end of the trunk 2 under the shaft 5 and the wheels 4..

The devices for preventing the return of the cobs along the under runs of the chain belts 3 consistl of fingers which are mounted upon the cross bar 6. Each finger is provided with a shank portion 7 having elongated openings 8 through which securing bolts 9 pass. The said bolts 9 also pass through the cross bar 6 and b v loosening the bolts the Shanks 7 may be adjusted in a direction longitudinally of the trunk 2. The shanks 7 are located under the disks or wheels 4.

The material of which the fingers are formed at the rear ends of the shanks is carried up into a hump l0 which extends approximately concentric with relation to the shaft 5 and the wheels 4. From the hump the material is carried down and away from the wheels i forming a curved extremity 1l. There is sufficient space between the upper surfaces of the fingers and the lqwer portions of the peripheries of the wheels 4t to permit the chain belts with their attachments to pass between, but not sufficient room to permit the chain belts to carry cobs through the said space. Consequently as the cobs are carried up on the upper runs of the chain belts 3 to the delivery end of the trunk 2, the cobs will come in contact with the upper portions of the humps 10 and will be knocked from the chain belts and will fall down along the curved extremities 11 away from the machine. Thus the possibility of the cobs returning with the lower runs of the chain belts is prevented and the damage to the machine and its parts incident thereto is eliminated.

Having thus described the invention, what is claimed as new is:

l. In combination with a corn sheller having a trunk with belts mounted for orbital movement along the same, means for preventing the return of cobs along the trunk consisting of spaced fingers adjustable longitudinally of the trunk at the delivery end thereof, said fingers having humps which extend up under the delivery ends of the belts.

2. In combination with a corn sheller having a trunk provided With chains mounted Jfor orbital movement along the same, means for preventing the return of oobs along the;

trunk consisting of spaced fingers mounted at the delivery end of the trunk and havingj humps Which extend up under the delivery ends of the belts, and Curved extremities extending down from the said humps away and around the delivery end of the chain belt.

4. ln combination With a corn sheller having a trunk with a chain belt mounted for orbital movement along the same, means for preventing the return of oobs along the trunk Consisting of a finger providedat one end with elongated slots, securing bolts passing through the slots and through the trunk, said finger having hump extending up and around 'the delivery end of the ohaiini'belt ln testimony whereof l :affix my signature in presence of two Witnesses.
