GRAIN-SEPARATOR.

Specification of Letters Patent.

Patented March 24, 1908.

Application filed July 22, 1907. Serial No. 384,887.

To all whom it may concern:

I Be it known that I, JonN A. NEUFELD, a citizen of the United States, residing at Mountain Lake, in the county of Cottonwood, State of Minnesota, have invented certain new and useful Improvements in Grain- 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.

The present invention has reference to improvements in grain separators, and it aims to provide an exceedingly simple and effective machine of that class designed primarily for separating wild oats and cockles from wheat kernels.

More especially, however, the invention resides in the provision of a separating machine of the celled or pocketed type in which the revolving inclined cylinder carries within its interior a partitioned trough in which a pair of screw conveyers are arranged, the conveyers differing in point of length so as to permit fthe longer to discharge the cockles, which lodge in the smaller cells of the feed end of the cylinder and fall into the adjacent compartment of the trough, through the openings at the front or discharge end of the cylinder, while the wheat kernels which are dislodged from the larger cells and fall into the forward compartment of the trough, are discharged by the shorter conveyer through-a chute at the forward end of the cylinder, the wild oats being likewise discharged through the above-mentioned openings with the cockles.

With the above and other ends in view the invention consists in the construction, combination, and arrangement of parts, all as hereinafter fully described, specifically claimed, and illustrated in the accompanying drawings, in which like parts are designated by corresponding reference numerals, in the several views. I

Of the said drawings, Figure 1 is a side elevation of the improved separator, Fig. 2 is a longitudinal section therethrough, Fig. 3 is a front elevation, Fig. 4 is a transverse vertical section through the hopper, Fig. 5 is a similar section through the cylinder, Fig. 6 is a fragmental plan view of the cylinder, with a portion of the casing broken away to illustrate the position of the conveyers, Fig. 7 is a vertical section on the line 7 -7 of Fig. 6.

Referring more particularly to the drawings the numeral 1 indicates the skeleton supporting frame of the machine, upon the rear end of which is mounted a feed hopper 2, provided with a regulating slide 3 whose lower edge is slightly cut away to form a channel through which the grain passes into a curved feed plate 4, formed by an extension of one of the sides of the hopper. Disposed directly above this plate is a shaft 5, arranged longitudinally of the. machine and projecting at opposite ends through the front and rear walls of the hopper, as shown, one end of said shaft carrying a flanged pulley 6 and the other end a handle 7. Said shaft is further provided with a pair of oppositely extending blades 8 which are arranged longitudinally thereof directly below the abovementioned channel and are adapted to feed the grain feeding therethrough to a second hopper 9 disposed beneath the main hopper 2 and provided with a spout 10 through which the grain is discharged into an inclined separating cylinder 11. One or other of the hoppers is provided with a fan attachment for removing dust from the grain to a certain extent, prior to the passage of the grain into the cylinder, the fan being disposed within a casing fitted in one of the side walls of the hopper and driven from any preferred source of power, the opposite side wall having a screen set thereinto, through which the dust escapes.

The cylinder 11 which is inclined forwardly and downwardly of the machine, is secured at opposite ends to the rims of a pair of wheels 21 and 4l rotatably mounted upon a shaft l2 supported at one end by a bearing block 13 carried by a bracket 14 secured to the frame adjacent the lower hopper 9, while its opposite end fits in a vertical slot formed in a second bearing block 15 secured to a cross-beam 1G attached to the forward end of the frame, the projecting end of the shaft being squared at such point and carrying a lever 17 provided at its lower end with a pin 18 fitting interchangeably in a series of o enings formed in said block, by means of w iich the position of the troughs and conveyers located within the cylinder may be adjusted, as hereinafter described. The cylinder 11 is preferably constructed of sheet metal and its upper or rear half is provided on its inner face with pits or cells 19, while the front or lower half of the cylinder is provided with similar depressions 20 whose diameter is somewhat greater than those 'first-mentioned. The cells may be formed by means of ahemispherical punch or similar implement. The lower wheel 21 to whose periphery the'adjacent end of the cylinder is secured, has formed upon its hub, or rigidly secured thereto, a gear 22 which meshes with a simi lar gear 23 secured to the adjacent end of a shaft 211 disposed longitudinally of the cylinder and provided with a screw conveyer 25, the rotation of the cylinder itself being effected by a belt 26 which passes around 'the rear end of the cylinder and around the pulley 6 above-referred to.

Disposed interiorly of the cylinder and extending approximately from end to end thereof, is a metal trough 27 whose opposite end walls are rigidly secured to the shaft 12. This trough is, 1n turn, provided with a second trough 28 whose rear wall 29 is in the nature of a partition of the first-named trough and is disposed in direct alinement with the dividing line between the forward and rear sets of cells, as shown in Fig. 2. T he forward wall 30 ofthe trough 28 which likewise forms that of the trough 27 is provided with an opening through which the shaft 24 extends the rear end of said shaft passing through a similar opening in the wall 29. This last-mentioned shaft is likewise provided upon its rear end with a gear 31 which is arranged exteriorly of the trough 28 and meshes with a gear 32 carried by a shaft 33 whose opposite ends extend through openings formec 1n the wall 30 and in the rear wall of the trough 27. The shaft 33 carries a screw conveyer 34 oppositely-arranged with respect to the screw conveyer 25. Both the troughs are approximately semi-cylindrical in shape and are so arranged that the bottom wall of the trough 27 lies in spaced relation to the inner face of the cylinder 11 while that of the short trough 28 is likewise spaced from the inner face of the first-mentioned trough. The cylinder 11 is further provided towards its front or lower wall with an inwardly directed annular flange 35 slightly in the rear of which is formed an annular series of circular openings 36, directly below these o enings is disposed a discharge chute 37 carried by the frame 1. The front wall 30 of the upper trough 28 is likewise provided with a discharge chute'38 which extends across the edge of the flange 35 and delivers the grain discharged thereunto by the conveyer 25 onto a third chute 39 which is likewise carried by the frame of the machine.

In the operation of the machine the grain is fed from the hopper 2 onto the platform or plate 4, from which it is discharged by the blades 8 into the second hopper 9 from which it passes into the separating cylinder which is slowly rotated by the belt 26. During the rotation of the cylinder the cockles, which are fed thereinto with the wheat will lodge in the small cells 19 and will be carried around with the cylinder being discharged from the cells at a certain point-in the rotation of the Acylinder into the rear portion or compartment of the trough 27 whence theyl are carried by the action of the screw conveyer 34 tothe forward end of said trough and are discharged through the opening 40 which is formed in the front wall of saidtrough; the cockles discharged through this opening fall through the openings 36 onto the chute 37, whence they are discharged into a receptacle, not shown. The wheat kernels, which are too large to become lodged in the cells 19, are gradually worked down towards the rear end of the cylinder until the cells 20 are reached, in which cells they become lodged and are carried around by the rotation of the cylinder and are discharged into the trough 28, passing through an opening in the front wall thereof onto the chute 38 and from thence to the chute 39. The oats and other foreign seeds are too large to become lodged in either set of cells, and, in consequence, travel directly along the inner face of the cylinder until they reach the openings 36 through which they fall onto the chute 37, together with the cockles. The provision of the annular flange 35 prevents the oats which may pass between the openings 36 from reaching the chute 39 and being discharged with the wheat kernels.

The shaft 12 which carries the

troughs

27 and 28 is capable of an adjustment by means of the lever 17 secured to the forward end thereof so as to dispose said troughs and their conveyers in proper position within the cylinder.

Vhile a duplex arrangement of trough and conveyer has been described and illustrated, it is to be understood that where the machine is designed merely to separate the wheat from the cockles one trough and one conveyer only will be made usefof, the operation of the machine in the last mentioned instance being similar to that above-described.
