"' HULLER.

Application liled March 20, 1925. Serial No. 16,875.

This invention relates to a separator and huller and particularly to a separator adapted for the hulling of beans. It has for one object to provide a machine in which stones, dirt and foreign matter generally will be automatically removed from the material before it reaches the separating zone. Thus the impurities are separated out from the material which passes through the ma chine, and the machine itself is freed from foreign matter which might damage it or cause clogging or unsatisfactory operation of the machine itself. Another object is to provide a machine in which the foreign matter separated out from the material as it passes toward the final separating zone is thrown out of the machine entirely. Other objects will appear from time to time throughout the specification and claims.

My invention is illustrated more or less in the accompanying drawings. wherein:

Figure 1 is a vertical longitudinal section of a portion of the machine showing the stone picker mechanism and associated parts.

Figure 2 is a side elevation of tion of the machine; I

Figure 3 is a side elevation similar to Figure 2 showing the reverse side of the machine and particularly showingthe driving connection.

Like parts are indicated by like charac ters throughout.

A represents generally the housing which encloses the mechanism. B is the enclosing and supporting housing within which it conveyor preferably of the belt type is mounted and which conveys the material to the separating zone. C is the belt conveyor provided with slats or cleats C. It revolves at one end about a pulley C which is carried-upon a shaft C C is a floor beneath the belt. C is an extended covering member which forms in effect an extension of the floor C and is curved about the shaft C It serves among other purposes to prevent material that por-v which is brought in on the conveyor from falling down and escaping the stone picker drum.

D is a shaking pan. Its lower end is slidably mounted-on the plate D and adjacent its upper end it is engaged .by one or more 7 rocker arms D carried on the rock shaft belt pulley F".

separator frame. D is a'lever arm which is attached to the rock shaft D and connected at its 'free end to a pitman D which is carried upon a crank pin secured in the pulley D on a shaft D The pulleyan'd shaft are driven, in a manner which. will be described below.

E is a concave provided with removable teeth E and in co-operation with it is the cylinder F mounted on a shaft F which carries at its outer end a driving pulley F adapted to be driven-by the. belt F from any suitable power source. Mounted in the cylinder F are removable teeth F. The details of the concave and. its associated parts will not be described further as they form no part of the present invention. F is an additional driving pulley mounted on the shaft F and adjacent to. the pulley F At the opposite end of the shaft is a third Mounted above the shaker panon a shaft G' is a stone picker cylinder G provided with teeth G which may be removable and are preferably rearwardly bent as shown. The shaft G carries at its outer end a belt pulley G which i is in contact with and driven by a belt N.

H is a beater carried on-a shaft H It is mounted behind and slightly above the stone picker cylinder and nerally above the cylinder F. The shaft 1 carries at one end a belt pulley H Between the pulley H and the pulley D on the shaft 1)? is a crossed belt H On the shaft H? at the opposite end from that which carries the pulley H is a second belt pulleyH.

I is a belt tightening pulley carried in an arm I which is pivoted at I and provided with a handle extension I. positioned adjacent to a quadrant .1 provided with a locking nut I by means of which it may be locked in fixed position with relation to the quadrant.

Between the carrier and the stone picker cylinder and slightly below the carrier is a shield J. This shield runs transversely across the machine throughout substantially the width of the carrier. It may be flexible and under certain circumstances the members C of the carrierwill strike it and deflect it slightly downward, and it is to ermit this that it is generally preferably exible. It is removably fastened to a. transverse member J K-is a deflector plate The arm is situated in the upper part of the machine. It is preferably metallic.

L is a stone receiving compartment having an open side L in which is hung a swinging curtain L preferable flexible. In the top of the compartment L is hinged a cover L. The compartment L has in its bottom, raised slat members L. M is a swinging cover for aportion of the main casing which may be raised for inspectlon purposes and to permit entrance into the machine for repairs and other pur oses.

N is a belt which is mounted a out the pulleys F H, G and I. O is a sprocket on the carrier shaft O is a sprocket pinion on the shaftD and is a chain about the two 3 rockets by means of which the carrier 'sha t is driven from the shaft D". O is'a chain tightening sprocket pinion adjustably mounted at O.

P is a flexible downwardly depending curtain mounted at the mouth of the machine and depending downward toward the carrier belt and into the normally entering path of the material which is carried there by. When material is being fed to the machine this material is frequently deflected rearwardly. During the operation of the.

machine any material which may be driven toward the feeding opening of the machine will strike the curtain and will be deflected by it downwardly and be prevented from flying out of the machine.

Although I have shown an operative device, still it will be obvious that many changes might be made in size, shape and arrangement of parts without departing materially from the spirit of my invention; andv I wish, therefore, that my showing be taken as in a sense diagrammatic. Particularly where in the specification and claims I have used the word grain I mean grains of any sort. It might be wheat, oats, beans or any material which in growth is associated with pods, chaff, stalks and other matter from which it must be separated.

The use and operation of my invention are as follows:

When the machine is to be used, the mechanism is set in operation and material is placed 11 on the feeder and by it carried toward t e feed opening. Material passes off of the feeder carrier and against the stone picker cylinder. The teeth of this cylinder contact stones. lumps of dirt and other foreign matter and drive them upwards against the deflecting plate K and from this plate they are deflected against the upper curtain which hangs in the door way of the chamber L. the heavy material swings the curtain and passes into the chamber, and lighter material fails to swing the curtain and drops downward again into the machine and is carried forward toward the hulling and separating zone.

Some material will be deflected outward toward the feeding opening and would be driven out of the machine. To prevent this the curtain P is hung in the opening and material driven toward the feeding opening strikes the curtain and is deflected by it downward and drops into the stream of material coming into the machine and is prevented from flying from the machine. Thus means are provided both for separating foreign matter from the material to be liullcd and separated. and for preventing the accidental discharge of material from the machine by reason of the action of the stone picker.

All remaining material is, of course, caughtby the stone picker cylinder and carried upward and over, and thrown in the direction of the beater. The heater strikes this material and forces it downward again toward the concave and the threshing cylinder which co-operates with it. The heater also sets up an air current which further blows and diverts material downward toward the concaves and the threshing zone.

The driving mechanism operates as follows:

The main cylinder shaft F is driven from any suitable power source. From this shaft the beater shaft, and the stone picker shaft are driven. From the beater shaft H the shaft D is driven and from the shaft D the carrier shaft C and the shaker pan D are driven.
