GRAIN-SEPARATOR.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed June 24, 1907. Serial No. 380,624.

To all whom it may concern:

Be it known that we, JOHN L. BLACK and LEO KIPPING, both citizens of the United States, and residents of St. Louis, Missouri, have invented certain new and useful Improvements in Grain-Separators, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to a grain separator, our object being to construct a simple, inexpensive, and eflicient screening or separating apparatus whereby all foreign matter and substance, such as wild onions and cheat is thoroughly separated from wheat and the like, thus thoroughly cleaning said wheat and leaving it in a high grade condition for milling or market purposes.

To the above purposes, our invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in the claims, and illustrated in the accompanying drawings, in which 2- Figure 1 is a vertical section taken through the center of a separator of our improved construction; Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1; Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 1; Fig. 4 is a vertical section of the blower nozzle made use of in our improved separator; Fig. 5 is a plan view of the nozzle; Fig. 6 is an enlarged vertical section taken on the line 66 of Fig. A; Fig. 7 is a transverse section of the upper screen of our improved separator, and illustrating the manner in which the grains of wheat ride thereon and pass through.

Referring by numerals to the accompanying drawings :1 designates a housing, preferably constructed of timber in rectangular form, and arranged in the top of saidhousing, at the right hand end thereof, is a vertically disposed chute 2, which receives the unscreened grain; and vertically disposed in said chute is a plate 3 hingedat its upper end, as desi 'nated by 1; and pivotally connected to the ower portion of said plate is a rod 5, which extends through one of the walls of the chute 2, the outer end of said rod being screw threaded and receiving a wing nut 6. liocated on said rod, and interposed between the wing nut and the wall of the chute 2, is an expansive coil spring 7, which arrangement allows the lower end of the plate 3 to yield rearwardly, and thus regulate the discharge of grain through the chute 2, corresponding to the amount of grain delivered into said chute.

Arranged within the housing 1, a short distance below the top thereof, is a rectangular frame 8, which is inclined, with the highest end. immediately beneath the chute 2; and arranged for rotation on the end timbers 9 of this frame is a series of pins or keys 10, which carry the ends of longitudinally disposed wires 1.1, which "form the upper screen of our improved separator.

Journaled for rotation in the side rails of the frame 8, adjacent the upper or right hand end thereof, is a shaft 12, one end of which extends through the side walls of the housing 1, and fixed on said extended end is a pulley 13. Arranged on this shaft 12 is a sleeve 14 which carries a flexible tab or flange 15, the end of which strikes against the wires 11, thus continuously vibrating the same when the shaft 12 is rotated.

Arranged immediately beneath the screen frame 8 and occupying a plane parallel there with is a row of transversely disposed slats 16, the same being obli uely positioned so as to deflect the grain am like matter toward the left hand as it falls from the wires 11 on to said slats.

Fixed to the lower end of the screen frame 8 is a chute 17, in the form of a plate, which leads downwardly and discharges into a receptacle 1S.

Arranged a short distance below the slats 16 is a rectangular frame 19, which is positioned at a greater angle of inclination than is the frame 8, and arranged on the end tinibers of this frame 19 are keys 20, which carry the ends of longitudinally disposed wires 21, which are arranged closer together than are the wires 11 of the upper screen.

Arranged beneath both ends of the frame 8 are plates 22 forming chutes which deflect the grain discharging through the end slats onto the wires 21.

Leading from a point immediately above the lower end of the screen frame 19 is a plate 23, which discharges into the receptacle 1S, and arranged immediately above this plate 23 is a curved deflector plate 24.

Arranged immediately beneath the lower end of the screen frame 19 is a receptacle 25, and immediately beneath the lower end of ately beneath the wires 21; and below the space between the plates 23 and 24. Arranged within this nozzle 30 is a triangular deflector plate 31,which is hinged at its ends, as designated by 32, to the end walls of the deflector plate 31, and theend walls of said deflector plate terminating in the lower end of the nozzle 30 immediately above the discharge end of the inlet pipe 29. This plate 31 is bent slightly at its center, as designated by 33, in order to bring the center of said plate against the front wall of the discharge nozzle, whereas the ends of said plate lie immediately adjacent the rear wall of the nozzle. This arrangement of the deflector plate provides for a more even distribution or discharge of the blast of air through the nozzle. Arranged in the pipe 29 is a damper, or valve, 34, by means of which the blast through said pipe is accurately regulated. The shaft on which the fan 28 is mounted eX tends through one of the side walls of the housing 1, and fixed on said extended end is a pulley 35 and connecting said pulley with the pulley 13 is a belt 36, thus providing means for rotating the shaft 12.

hen our improved separator is in operation, the shaft carrying the fan 28 is rotated, and as a result, a blast of air is forced through the pipe 29 and discharges from the mouth of the nozzle 30 and passes from thence between the wires 21 of the lower screen; and from thence upward and between the deflector plates 23 and 24. At the same time the shaft 14 is rotated, being driven by the belt 36, and the flexible tab or flange 15 engages the wires 11, causing the same to vibrate continuously.

The grain to be cleaned and separated is delivered in any suitable manner into the chute 2, and when a sufficient amount has accumulated therein, the weight thereof will force the lower end of the plate 3 rearward, and a quantity of the grain will discharge onto the upper end of the upper screen. The wires of this screen being continuously vibrated cause the grain to gradually move toward the lower end of the screen, and during this action the particles of dirt, small seeds, and smaller kernels of grain pass between the wires of the screen, between the slats 16, to the lower screen, and, after passing therethrough, fall onto the plate 27 and pass thereover into the receptacle 26.

The wires 18 are so spaced as that under ordinary conditions the grains of wheat cannot readily pass between said wires; but as said wires vibrate and the grains of wheat travel toward the lower end of the screen, as a result of said vibration, said grains of wheat tend to assume positions with their greatest lengths parallel with the wires 11, as this is the position of least resistance in the travel over the wires.

Each wheat grain is provided with a longitudinally disposed groove, and sooner or later during the travel of the wheat over the screen, the grains will so adj ust themselves as that the wires of the screen occupy the grooves in said grains; and, when so posi tioned, the grains will turn or fall to one, side or the other, and thus readily pass through the spaces between the wires 11. After thus passing through the upper screen, the grain strikes against the slats 16 and is deflected thereby outward onto the lower screen, which, being finer than the upper screen,

holds the full sized marketable grain, which in turn discharges over the lower end of the lower screen into the compartment 25.

All straw, leaves, or like material falling onto the lower screen will be quickly removed by being blown therefrom by the blast of air issuing from the nozzle 30, and said like material will pass between the plates 23 and 24 and be deposited in the receptacle 18.

The wild onions, cheat, and similar refuse, which are usually larger in diameter than are the grains of wheat, will not pass through the upper screen, but will be carried thereon and finally discharge at the lower end thereof and be carried over the plate 17 into the compartment 18. Thus, the refuse, consisting of wild onions, cheat, dust, straw, leaves, and undersized grains, is easily and 'quickly separated from the wheat, the latter after passing through the machine being in prime condition for the market or milling purposes.

The tension of the wires of both screens can be accurately regulated by manipulating the keys or pins 10 and 20, and the degree of vibration of the wires 11 of the upper screen being regulated by the amount of tension on said wires.

The deflector plate 31 arranged in the nozzle 30 provides for an even distribution or blast of air through said nozzle 30, and the damper 34 regulates the blast through the pipe 29 to the nozzle 30.

Our improved machine requires practically no attention after being set for opera tion, and possesses superior advantages in point of simplicity, durability, and general efficiency.
