PNEUMATIC SEPARATOR.
Specification of Letters Patent.
Patented Sept. 17, 1907.
Application filed September 25,1906. Serial No. 336,089.
To all whom it may concern:
Be it known that we, ANDREW M. ANDERSON and CORNELIUS QUESNELL, citizens of the United States,
residing at Moscow, in the county of Latah and State of Idaho, have invented a new and useful Pneumatic Separator, of: which the following is a specification.
This invention relates to pneumatic separators for use in cleaning grain after it has been threshed.
The object of the invention is to provide simple and efficient means whereby the grain may be discharged into an air blast and all the chaff or light particles blown therefrom while the desirable product is discharged by gravity and conveyed to another similar separator whereby the separation is completed.
With the above and other objects in view the invention-consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.
In the accompanying drawings is shown the preferred form of the invention.
In said drawings: Figure 1 is an elevation of the separating apparatus; Fig. 2 is a section througlrone of the separator tubes; Fig. 3 is a section through the other tube; Fig. 4 is a detail of a portion of the tube and showing the outlet chute; Fig. 5 is a plan view of the complete apparatus.
Referring to the figures by characters of reference, 1 is a fan casing having a fan 2 therein for driving air through flues 3 and 4 and one of these fiues 3 opens into an elongated tubular casing 5 which is disposed at an incline and has a downturned upper end 6 which constitutes an outlet for the air blast. The hopper 7 is disposed upon the upper inclined portion of the tube and communicates with the interior of said tube through an opening 8. An outlet opening 9 is formed in the lower inclined portion of the tube 5 at a point below the open ing 8 and a tubular extension 10 projects therefrom and constitutes a discharge spout. A baffle plate 11 extends into the tube from the lower portion of the opening 9. The spout 10 is adapted to discharge grain into a screen A which may be of any desired construction preferably such as described and claimed in a co-pending application filed by us in the United States Patent Office. From this screen it is discharged into a trough 12 in which is arranged a worm 13. This worm will convey the grain to the feed hopper 14. of a tube 15 having its upper end downwardly curved to form an outlet while this lower end is enlarged as at 16 to permit a sack to be fastened thereto. The flue 4 opens into the tube 15 between the hopper 7 and the enlarged lower end thereof. An elevator 17 of any desired construction is arranged to hoist grain and discharge it into the hopper 7 and this elevator is adapted to be driven by a shaft 18 having a sprocket 19 thereon. A chain 20 serves to transmit motion from this sprocket to a sprocket 21 on a shaft 22 which is connected by a universal joint 23 with the worm 13. Any suitable mechanism may be utilized for driving the fan 2 and illustration and detailed description thereof is deemed unnecessary.
In using the separator herein described the fan 2 is set in motion in any desired manner and will force blasts of air into the tubes 5 and 15 through the fiues 3 and 4. These air blasts will discharge through the upper outlet openings of the tubes. The elevator 17 will discharge the grain into the hopper 7 from which it will fall by gravity through the opening 8 and on to the lower inclined surface of the tube 5. In dropping upon this surface of the tube the grain must necessarily pass through the air blast and therefore any chaff or light particles commingling with the grain will be blown from the outlet 6 while the desirable material will roll downward along the lower inclined face of the tube and on to the baffle plate 11 which will direct it into the chute 10. This baflie plate not only constitutes a stop for directing grain into the chute 10 but also serves to hold the blasts away from the lower surface of the tube so as to not unduly interfere with the downward move ment of the grain. The grain is discharged from the chute 10 into the separator A which, as hereinbefore set forth, may be of any preferred construction and may operate in any desired manner. From the separator the grain is discharged into the trough 12 and conveyed by the worm 13 into the hopper 14 of the tube 15. Upon being discharged into this tube the grain is met by the blasts from flue i and any additional chaff commingling therewith will be blown through the top of the tube 15 while the heavier and more desirable product will fall into the sack which may be fastened to the enlarged end of the tube 15. It will be seen that by employing pneumatic separators which are arranged in this manner the grain will be thoroughly cleaned and any undesirable particles which will not be removed by the blasts in the first tube 5 will be driven from the grain while in the second tube 15.
The preferred form of the invention has-been set forth in the foregoing description but we do not limit ourselves thereto as we are aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and we therefore reserve the right to make such changes as. fairly fall within the scope of the claims.
What is claimed is:
1. A pneumatic separator comprising a casing, means therein for establishing an air current, fiues extending upward from the casing and having air outlets at their upper ends, a hopper upon the upper wall of each flue at a point between its ends, said hopper opening into the fine, and an outlet spout depending from the lower wall of each flue, the material admitted to the fines from the hoppers belngmovable by gravity across the fiues and into the outlet spouts independently of the air current within the fiues.
2. In a pneumatic separator the combination with a casing, and means therein for establishing an air current;
of upwardly extending flues extending from the casing and having air outlets at their upper ends, a feed hopper opening through the upper wall of each flue at a point between the ends thereof, an outlet spout extending from the lower Wall of each flue and disposed to receive material discharged by gravity from the hopper and across the flue, means for supplying material to the hopper of one of the fiues, and means for conveying material from the spout of said flue to the hopper of the other flue.

In testimony that we claim the foregoing as our own, We have hereto affixed our signatures in the presence of two witnesses.
