SEPARATOR.

Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed January 21, 1915. Serial No. 3,529.

To all whom it may concern.

Be it known that I, JAMEsD. Moonn, a citizen of the United States, residing at North VVilkesboro, in the county of Wilkes and State of N orth' Carolina, have invented a new and useful Separator, of which the following is a specification.

This invention relates to separators, one of its objects being to provide a structure of this type particularly designed for use in the separation of grits from bran and meal, novel means being provided whereby the separation is effected accurately and readily, the machine being of a simple and compact construction.

l/Vith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a vertical longitudinal section through the separator. Fig. 2 is a plan view thereof. Fig. 3 is a section on line AB Fig. 1. Fig. 4 is an end elevation.

Referring to the figures by characters of reference 1 designates a main supporting frame having hangers 2 suspended therefrom and connected to the side walls 3 of the separator. These side walls are arranged between the sides of the frame 1 and can be connected in any suitable manner, there being a screen 41 extending longitudinally of the separator structure for a portion of the length thereof and merging into another or coarser screen 5 likewise extended longitudinally. The meeting ends of the two screens 4: and 5 may be mounted on a cross strip 6.

Suitably mounted under the fine screen 4 is a hopper 7 for the reception of meal passing through said screen, this hopper being adapted to discharge its contents into any suitable receptacle provided therefor.

Extending under the screen 5 is an inclined board 8 adapted to discharge screenings into a flue 9 which is inclined downwardly and inwardly under the board 8, there being an outlet spout 10 in the bottom of said flue 9 at its lowest point and through which grits are adapted to be discharged. An outlet spout 11 is provided at the outer end of the flue 9 and the top of this outlet spout is curved upwardly and inwardly, as at 12 and terminates adjacent the discharge end of the screen 5, there being a passage 18 between the said screen and the top 12 for the reception of tailings. An arcuate wind shield 1 1 extends across the upper end of the flue 9, the upper end of this shield being extended into the space between the screen 5 and the inclined board 8, while the lower end of the shield is extended into the spout 11. A blower casing 15 is arranged under the hopper 7 and has an outlet flue 16 which discharges into the flue 9 close to the outlet 10. It will be seen by referring to Fig. 1 that the flue 9 has its top bowed upwardly above the outlet 10, as shown at 17 thus to provide a deflector for air entering the flue 9 from flue 16. A pitman 18 is connected to the frame 3 of the separator and receives motion from a disk 19 secured to a shaft 20 which is adapted to be actuated in any suitable manner. Thus it will be seen that rotation of the disk 19 will result in the reciprocation of the separator screen 4-5.

In using the apparatus the parts are set in motion, after which the materials to be separated are placed on the screen 4. The finest grade of material such as meal. will gravitate through the screen 4t and into the hopper 7, while the coarser material will pass onto the screen 5 where a second separation will be effected, the grits passing through the screen and onto the inclined board 8 while the coarser material, such as bran, will be discharged as tailings from screen 5 and onto the shield 14 and be directed into the spout 11. The grits discharged onto the board 8 will gravitate into the upper end of the flue 9 and will drop across the upper portion of the flue onto the screen 21 which will operate to spread the grits so that said grits and any particles of bran which may be adhering thereto will be separated and will then fall downwardly through the screens 21 and onto the bottom of flue 9. As the air enters the lower end of flue 9 from flue 16 it will strike the curved top wall 17 and thus be deflected downwardly so as to thoroughly agitate the grits before they pass outwardly through the outlet 10, this agitation being sufiicient to separate from the grits any bran which may be adhering thereto so that said bran will thus be blown outwardly against the wind shield 14: and be deflected downwardly into spout 11 where it will commingle with the bran discharged into said spout from the end of screen 5.

Especial importance is attached to the particular arrangement of the curved top 17 so that the air current is deflected downwardly onto the bottom of the flue 9 at a point above the outlet 10. The screen 21 is of the same mesh as screen 5 and, therefore, as before stated, the grits, when discharged from the board 8 will fall onto this screen 21 and will be scattered transversely within the flue 9 before falling through the screen 21, thus insuring the separation from the grits of any bran adhering thereto so that the light bran will be blown from the flue 9 while the grits will gravitate as before described.

What is claimed is 1. A separator including alining fine and coarse screens, means for receiving screenings from the fine screen, an outlet spout, means for directing tailings into the outlet spout from the coarse screen, a flue extending downwardly away from the spout, an inclined board for directing screenings from the coarse screen into the flue, a blower casing, and means for directing an air blast from the blower casing and longitudinally of said flue, said flue having an outlet between its ends, the top of the flue being curved upwardly in the line of the air cur rent thereby to deflect the current downings into the flue, means for directing an air blast longitudinally through the flue and against the wind shield into the spout, said flue having its top bulged upwardlyadjacent the outlet thereby to deflect the air current downwardly against the bottom of the A flue at a-point above the flue outlet. 3. A separator including a screen, an inclined board thereunder, an outlet spout,

means for directing tailings from the screen and into the spout, a flue extending down-- wardly from the spout, and a screen of the same mesh as the first named screen for receiving material from the inclined board, said screen being located inthe upper end portion of the flue, and means for directing an air current longitudinally within the flu and into the outlet spout.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses. V
