BrieiiyA described, the invention embodies fatfgrain separator wherein a plurality of 'Vibratory screens is arrangedwithina casing,ithe screens being arranged'in super,-

posed relations and ofrelativelyincreasing "finer mesh ,toward the lower screen, the Vupper ,screens being given alternating re-` ciprocatory vibratingv motionswhile the lower screens are carried by mounting plates attached to lvertically ldisposed crank shaftsk for imparting a circular vibratory being gradedgbyvthescreens for `delivery pinto separate compartments provided with jmotion'thereto. A .fan blower is arranged Y in onel-end of thelcasing, and is employed forgdirecting theblast of air over. the -.screens |to remove `therefrom the chaff, the I grains and belt connections, theseveral Ascreens and v fan are-driven from a single 'source ofpower 7 while the grain. delivered -to the screens is Acontrolled by a manuallyloperable zgate. grain separator constructed in :accordance ,Referring more in detail to .thev accompanying drawings and particularly-to |Figure 3,;ther`e is illustrated agrainseparatorembodying a casing comprisingside walls l, a bottom ywall'2-and 'a top wall, onel end of Athe casing being open as indicated fat 4 whilethe other end thereof'is', closed vby an outwardly archedvwall', the casing beingsupported onl corner legs 6.

An open-ing isprovidedin the upper wall A pairof separating screensisl disposed within "thecasing, adjacent the upper end` thereof and directly beneath the hopper i for vibratory reciprocating movements, these screens being more clearly shown in Figures 3 and 8, each including a rectangular frame embodyingside bars 9 and transverse end bars 10 and 11, the transverse bars l0 and 1l carrying end extensions 10 and 11 for purposes presently to appear. The frames are provided with wire screens 12 and '13, the mesh of the screen 13 being relatively liner than the mesh of the screen 12, while the screen 13 and its supporting frame is of greater length than the superposed screen to insure the deposit of all grains sifted through the screen 12. The mounting of the reciprocating-screens embodies transversely extending U-shaped brackets 14 clearly shown in Figures 3, 4, and?) having the ends thereof supported in the upper wall 3 of the casing. .Adjusting screws 15 extend perpendicularly through the brackets 14 and are vertically adjustable therein by the nuts 16 threaded on the screws 15. As shown in Figure 6, the lat-eral extensions 10 and 11 of the frame supporting the lower screen 13 extend laterally of the extensions of the frame supportingl the upper screen 12, each extension carrying an eye bolt 17 to be engaged by links 18 and 19, 'the other ends of the links being attached to the lower ends of the adjusting screws 15. The forward transverse bars 11 of each screen supporting frame are provided with elongated slots 20 to permit the end escape of the small grains for delivery into a suitable receptacle to be later described.

A circularly moving shaking or vibrating screen construction is disposed beneath the reciprocating screens 12 and 13 and is shown more clearly in Fioures 3, 6, and 7, the side walls 1 of the casing having bracket arms 21 secured thereto and projecting inwardly in opposed relations with longitudinal strips 22 extending between the inner ends of the bracket arms. vertically disposed crank shafts 23 are journaled in the bracket strips 22 with the crank portions 23 constituting supports for the shaking screen frame. This frame embodies side plates 24, shown in de tail inl Figure 7 ,carrying outwardly directed flanges 25 having'the edges thereof notched as at 26 for Areceiving the crank portions 23 of the crank shafts 23 with the open ends of the notches suitably closed by a strap or other device. The inner faces of the plates 24 are provided with longitudinally extending inclined guide cleats 27 between which the screens 28 are slidably mounted, the screens being of relatively lincreasing finer meshes extending from the upper screen to the lower screen.

A shaft 29 extends transversely of the casing adjacent the arched end 5 and has seeuredthereto a fan wheel 30 travelling in the direction of the arrow as indicated in Figure 3 for purposes of separating the chaff from the grain and for separating the grains when sifting through the lower screens 28.

The power mechanism for operating the screens 12, 13and 28, andthe fan wheel 30 embodies a power shaft 31 carrying a motor driven pulley uw and a gear wheel -b-, the shaft. 31 being journaled in one of the side walls of the casing as shown in Figures 2 and The shaft 29 j ournaled transversely of the vcasing has secured to one projecting end thereof, as shown in Figure 4, a pinion c in engagement with the gear Ziand is further provided with a stepped pulley CZ- arranged adjacent they pinion Uw.y the opposite end of the shaft 29 projecting from the other side of theca-Sing carrying a stepped pulley 'e-. As shown in Figures 2, 3, and 4, the crank shaft 32 extending,transversely of the casing is provided upon one projecting end thereof with a stepped pulley -f having a belt connection 33 with the stepped pulley e-, the vcrank portions 34 of the shaft 32 having link connections 35 with the brackets 36 upon the transverse bars 10 of the vibrating screen frames, thecrank portions 34 ofthe shaft 32 extending in opposite directions to create an alternating reciprocating movement of the screens 12 and 13, as clearly shown in Figure3.

il stub shaft 37 journaled in one sidewall of the casing carries the stepped pulley g upon the outwardly projecting end thereof that has a beltV connection 38 with the stepped pulley -d-. The lower ends of the crank shafts 23 as shown in Figures 5 and G carry gears 39 meshing with a central gear 40 which in turn carries a bevel gear 41 for engagement with the bevel pinion 42 upon the` inner `end of the stub shaft 37, the rotation of the shaft 37 communicating motion4 to the crank shafts 23 in an obvious manner.

The grain in the hopper 7 is delivered to the upper screen 12 under control ofthe sliding gate 8, thescreens 12 and 13 being alternately vibrated in opposite directions by their' link connections 35 with the'crank shaft 32. lThe air draft created by the fan will separate the chaff from the grain and discharge the same through the open end 4 of the casing as illustrated in Figure 3. The grain will sift through the screens 12 and 13 and the air draft will cause the finest grains to be discharged from the ends of the screens 12 and 13 into the hopper43 as shown in Figures 2 and 3, the hopper beingy provided with a lateral outlet chute 44. rlhe grain sifting through the screens 12 and 13 will be received on the upper screen 28 of thelower screen construction, the screens 28 carried by tht side plates 24 being given a circular shak-v i hopper provided with the inclined bottom wall 45 and laterally discharged through the side chute 46. The grains remaining on the lower screen 28 will fall by gravity, due to the shaking motion of the screens and by the reverse inclination thereof as shown in Figures 3 and 6, into the discharge chute 47 shown in Figure 3. It will` therefore be seen that the reciprocating screens and the rotatably movable screens as well as the fan 30 are driven from a central power shaft, it also being noted that the relative positions of the screens 12 and 13 are readily changed by adjusting the screws 15.

The air draft created by the fan 30 will completely separate the chaff from the grain and discharge the chaff through the open end 4 of the casing, the finest grains being separated from the chaff by falling into the end receptacle 43 as above described. Byvproviding reciprocating and rotary motion screens, the screens are given a complete shaking motion providing for a better cleaning and grading of the grains, the quantity of grain material fed to the machine being controlled by the sliding gate 8. A receptacle 4 8 disposed at the rear end of the machine may be employed for storing the screens or tools and like devices for use in the operation of the machine. To provide for a continuous draft through the casing, one side wall thereof is provided with an opening 3 adjacent the fan 30 to afford a air inlet for the fan.

While there is herein shown and described the preferred embodiment .of the invention,

it is nevertheless to be understood that minor changes may be made` therein without de` parting from the spirit and scope of the invention as claimed.

What is claimed as new is:

1. In a grain separator of the type described, a casing, a feed hopper for the upper end thereof, a set of screens within the casing arranged `beneath the hopper, means for moving the set of screens in a circular path, said. means including perpendicular side plates for removably supporting the screens, vertically disposed crank shafts carrying the side plates, and means for rotating said crank shaft.

2. In a grain separator of the type de,

cleats carried by the opposed faces ofthe side plates, sifting screens slidably positioned in the cleats between the side plates, vertically disposed crank shafts positioned outwardly of the side plates, outwardly directed horizontal flanges carried by the .sidev plates, and having notched edges receiving the crank portions of the shafts, and means for rotating the crank shafts to impart a circular motion to the sifting screens.

In testimony whereof I aflix my signature in presence kof two witnesses.
