To all whom it may concern:

Be it known that l, SILAs HoUTs, a citizen of the United States, residing at Weeping Water, in the county of Cass, State of Nebraska, have invented certain new and useful Improvements in Corn-Sheller Separators; and I do hereby declare the following to be a full, clear, and exact description of 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 conveyers for corn shelling machines and has for its object to provide a simple device of this nature which will, during the process of conveying, effectually separate the shelled corn, cobs and weed seeds and deposit them in separate receptacles.

The invention resides in the provision of an endless chain conveyer, which is mounted in a frame, a flooring included in the frame, a screen arranged in the flooring intermediate its ends, and a grille carried by the flooring. p i i The invention further resides in the provision of a novel form of grille and in a novel manner of securing the grille rods to their support.

1n the accompanying drawings, Figure 1 is a plan view of the conveyer. Fig. 2 is a vertical longitudinal sectional. view therethrough. Fig. 3 is a detail transverse vertical sectional view through the same, and Fig. 4 is a'detail perspective view of the grille end of the `conveyer flooring.

Referring more specifically to the drawings, the conveyer comprises a frame including side boards 5 which are connected by means of a flooring 6 which extends `from the rear end of the side boards 5 to a point adjacent the forward ends thereof and in a plane intermediate the upper and lower edges of the side boards 5. Journaled in the side boards 5 adjacent their forward and rear ends respectively are shafts 7 and 8 upon which are secured pairs of sprocket gears 9 over which are engaged sprocket chains 10, the said sprocket chains being mutually connected by means of conveyer slats 11 which are secured at their ends to suitable links in the chain. The shafts 7 and 8 are journaled in such position that the upper stretch of the conveyer thus formed will travel over the flooring 6 with the slats 11 in contact'therewith to convey the shelled corn, cobs, etc., over the said flooring 'for a purpose to be hereinafter described. A sprocket gear 13 is secured upon the shaft 8 outwardly of the adjacent side board 5 and with the said sprocket gear is connected a sprocket chain 14 leading from a similar gear or a drive shaft (not shown) journaled in the shelling machine to which the conveyer is attached.

An opening 15 is formed in the floorof the conveyer,

and secured to the floor and extending over` the opening is a wire screen 16, although a sheet of any foraminous material will answer the purpose equally well. The function lor this screen will be presently explained in connection with the description of the operation of the conveyer.

As stated, the forward end of the floor 6 terminates short of the forward ends of the side boards 5, and extending from one to the other of the said side boards in advance of the forward end of the floor and slightly rearwardly of the shaft 7 is a cross piece 17. Secured at their rear ends to the upper face of the floor 6 at its forward end and resting upon the cross piece 17 with their forward ends extending beyond the same and above and beyond the shaft 7 is a series of spaced parallel rods 18 which form a grille. The connection of these rods 18 with the floor 6 is had by threading the rear ends of the said rods as at 19 and bending them at right angles as at 20 to extend through openings in the oor, there being nuts 20 engaged upon the said threaded ends of the rod and bear against the under side of the floor.

ln operation, the shelled corn, cobs, etc., are deposited upon the conveyer floor 6 and are carried along the same by means of the conveyer slats 1l and over the screen 16 and grille formed by the rods 18.` Any weed seeds that may be among the shelled corn and corn cobs will fall through the screen 16, it being understood that the mesh of the screen is too fine to permit passage of the grains of corn therethrough, and the said grains of corn will fall through the grille and into a suitable receptacle. The bars forming the grille are so spaced that, although the grains of corn may pass therebetween, the cobs cannot do so and are therefore carried over the grille and deposited from the conveyer beyond the shaft 7.

What is claimed as the invention isz- A device of the class described comprising a frame including a floor, van endless conveyer having one of its runs arranged for travel over the floor, said floor being provided with openings, a screen disposed upon the floor and across one of the openings, and rods each having one of their ends engaged through the floor at the inner edge of the other opening and threaded, a nut engaged upon the threaded end of each rod and arranged to rigidly connect it with the floor, said rods being extended above the 0pen ing and beyond the corresponding end of the door and having their ends turned slightly downwardly outside of the end of the door.

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