Y shaft 38.

A member 4l is placed below back board 31, and forms with the lower portion of the liront wall of chamber 26, a tunnel-like opening 32. Member 41 also serves as a brace Lt'or the inverted V-shaped hump formed by incline 27 and back board 31.

A fan 42 is mounted on a shaft 43 disposed in the upper part of chamber 26. Shaft 43 is supported in bearings 44 located in the side walls of chamber 26, and is prevented from endwise displacement by collars 45. A casing 46 surrounds the suction fan 42, openings 47 being provided for ingress of air and an opening 48 for the exhaust. Vertically movable dainpers 49 at each side et casing 46 permit partial closing ot the openings 47, to regulate the suction of the fan. Pulleys are provided at each end of shaft 43.

' One of the pulleys on shalt 43 is connected to a suitable source ot' power (not shown), and the other pulley is coupled by a belt 50 to a pulley on shaft 19. Belt 51 in turn couples the otherv pulley on shaft 19 with the pulley on shaft 38. As is clearly shown lin Fig. 3,'the sizes of these various pulleys are so chosen that lshafts 19 and 38 will rotate at suitable speeds with respect to shat't 43. Of course, as will be readily understood, gearing might be substituted lor the pulleys, andv many `other changes might be made Without affecting the spirit of my invention.

In the operation of my separator, power is applied to cause rotation of shaft 43, which in turn, as above described, rotates shafts 19 and 88. Corn cobs are dumped on the vibrating screen 14 by some suitable means (not shown), such as a conveyor or a hopper, and the shelled corn drops through the openings in screen 14 into hopper 1G. A suitable bin (not illustrated) may be placed beneath the hopper 16 to receive the shelled corn. f The sieve may have perforations of any size suitable Jfor this purpose, andvmay be made of wire' mesh cloth.

The reciprocatory movement of the screen shakes the tailings down onto the tailboard 29. Here the powerful suction of fan 42 pulls upon the cobs and pulls them up ineline 27, at the 'same time stripping the remnants of liusks from them. VThese husks, together with all dust and dirt, pass through the fan and are rdischarged from opening 48 into ay suitable dust collector (not shown), from which the shucks may be removed for baling.

- TheV bin or hopper 32 is closed tightly by door 38, and opening is kept closed by the canvas strip and the material on the screen, so that the fan draws substantially all of its air through the channel iormed by openings and 2S. The corn cobs are not held in suspension by the tan, but are merely pulled or rolled up the incline 27, and then allowed to drop down into bin 32. They are discharged from this bin at periodic intervals by the operation of cam 4l), arm 3G and wire S35. which open the door 32? once tor each revolution of shailt. 3S, as above described.

'.lhe opening- 28 is too small to permit the corn cobs to drop thcrelln-ough, but thc heavy foreign materials, such as iron.A stones, concrete and the like, are not liflted by the lian and drop oil the Jiailboard 29 through the openings 2S and 42 into a. suitable receptacle (not shown) which may be placed 'to receive them.

A complete separation of shelled corn, toreign material, husks and dust, and cleaned cobs, is thus ell'ccted by my apparatus.

The member 27 may be made adjursttable to vary the incline up which the robs move as described. The meansl Alor this purpose may comprise a hinge 52 mounted at tlu` apex ot members 27 and 31, and an adjusting screw 533 threaded through a bracket secured to member 31 and held in a swivel socket attached to member 27. The member 27 is thus positively held in the desired position by the adjusting screw.

lllany changes might be made in mv invention within the spirit 'licrco' and I do notl wish to be limited except by thc prior art and the scope oil.3 the appended claims.

Having thus described my invention what l claim as new and desire to be secured by Letters Patent is:

1. An apparatus :tor separating shelled corn, husks and like particles from corn cobs, comprising in combination, a vibratory sieve for separating the shelled corn, chamber arranged at the tail end ot said sieve and having an opening through which the ren'iaining material passes from said sieve into the chamber, an upwardly directed incline arranged in said chamber adjacent said opening and the tail end ol`; said sieve so that the cobs are required to pass upwardly over the same upon enteringr the chamber, a settling chamber into which the upper end of the incline delivers, and means for creating a forced draft up said incline to lift the cobs over the same to permit them to drop into the settling chamber and to simultaneously draw oil the husks and like particles.

2. An apparatus for separating shelled corn, husks and like particles from corn cobs, comprisingin con'ibination, a vibra` tory sieve for separating the shelled corn, a chamber arranged at the tail end ot said sieve and having an opening through which the remainiiig material passes vfrom said sieve into the chamber, an upwardly di` Leearee rected incline arranged in said chamber adjacent said opening and above the tail end et said sieve so that the cobs are required to pass upwardly over the saine upon entering the chamber, a settling chamber receiving trom the upper end ot' said incline and suction tan arranged in the upper portion of said chamber and serving to create a forced draft up said incline to litt the cobs over the same and permit them to drop into said settling chamber and simultaneously dra-W oil the husks and like particles.

3. rlhe combination as claimed in claim l., in 'Which the settling chamber lor receiving the cobs after the same pass over said incline, is provided with a normally closed door, and automatic means Jfor periodically opening said door, whereby the greater part of .the draft is preserved7 in deliveringthe settled celos.

Il. in apparatus for separating shelled corn, like particles and husks from corn cobs, comprising in combination, Vibratory sieve for separating the shelled corn, a chamber arranged at the tail end ol said sieve and having an opening through which the material passes from said sieve into the chamber, an inverted ll-shaped hump in said chamber, one side of said hump terminating adjacent said opening and positioned to cause the eobs to travel up the same alter they enter said chamber, the other side of said hump delivering to a settling chamber and means for creating' a forced draltthrough said opening and up the side of said. hump to lift the corn cobs over the hump mail to tall into the settling chamber and to simultaneously draw ott the husks and like particles 5. 'lhe combination as claimed in claim d, in which said side oli the hump adjacent said opening is adjustable to Vary its angle with the horizontah d 'llhe combination .as claimed in claim et, in which the settling chamber tor reeeiving the cobs after they pass over said hump, is provided with a `normally closed door adjacent the bottom thereol and automatic means l'or periodically opening said door whereby the interruption oi the draft is reduced to a minimum in delivering' the settled cohs.

7. in apparatus tor separating shelled corn, husrs and like particles from corn cobs, comprising in combination, a Vibrator-y sieve for separating the shelled corn, a chamber arranged at the tail end ot said sieve and having an opening through which the remaining material passes :from said sieve into the chamber, said opening being restricted to minimize the admission of air, and an upwardly directed incline arranged in said chamber adjacent said opening and so positioned that the cobs are required to pass upwardly over the same upon entering the chamber, and means lor creating a forced draft up said incline to liit the cohs over the same and to simultaneously draw oil the husks and like particles.
