WILLARD A. PE'ITEYS, OF" WILGOX, NEBRASKA.

GRAIN CLEANER, SEPARATOR, AND DRIER.

To all whom it may concern:

Be it known that I, WILLARD A. Pn'r'rnYs, a citizen of the United States, residing at lVilcox, in the county of Kearney and State of Nebraska, have invented certain new and useful Improvements in Grain Cleaners, Separators and Driers, of which the follow ing is a specification. f This invention has for its object to provide .an apparatus for the treatment of grain including a novel type of, hood provided with a series of internal baffles over which the grain is caused to travel and which is -which the foreign matter is separated from the grain and conducted to a separate discharge spout in the receiving hopper.

With the above and other ob ects 1n view,

. as will appear as the description proceeds,

the invention comprises the various novel features of construction and arrangement of parts which will be more fully described herein and set .forth with particularity in the claims appended hereto.

Reference is had to the accompanying drawings forming a part of this application, in which like reference characters indicate the correspondin parts throughout the several views, in whic Figure 1 represents a front elevation, partly in section and partly broken away of the improved cleaning, separating and drying device,

Fig. 2 represents a perspective view of the receiving hopper detached, V

Fig. 3 represents a vertical sectional view through the ventilating hood, and

Fig.4- represents a vertical sectional view through the receiving hopper.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates generally the ventilating hood which consists essentially of front and rear walls 6 and a top 7 having a hinged section 8 facilitating access-to the interior of the'hood. The sides of the hood are open and thefront and rear walls are maintained in spaced relation by bolts Specification of Letters Patent. Patented J 11g 29 192() Application filed May 3, 1919. Serial No. 294,387. I i

9 to which the pulley supports -10, to be hereinafter more fully described, are attached.

The upper portion of the rear wall of the hood is formed with an inlet opening 11 through whichgrain is introduced into the interiorof the hood and a series of inclined and staggered bafile plates 12 is arranged beneath the opening 11 andis designed to cause the grain to pursue a circuitous course through the hood.

Aseries of hinge rods 13 is secured'to the opposed edges of the front and rear walls and pivotally support groups of ventilating shutters 14. The shutters',,when closed, lie in overlapping relation, as clearly shown in Fig. 3, to prevent the entrance of water intofthe hood and, as the bafiles 12 are arranged in spaced relation air is permitted to circulate through the hood to accelerate drying of the grain flowing therethrough.

A pair of pulleys 15 is supported at the outer terminals of the supports 10 and cables 16 are arranged thereover.

The front terminals of the several hinge rods 13 are directed angularly as at 17 and the angular terminals of each group of ventilating shutters are arranged in parallel relation and are connected by a rod 18 whereby the several shutters are caused to move in synchronism. One of the hinge rods of each group is also extended rearwardly of the hood 5 and is directed angularly and connected with one of the cables 16 for'convenience in adjusting the shutters to control the passage of air through the hood.

The lower open discharge end 20 of the hood is supported upon and communicates with an inclined chute 21 the lower terminal of which is supported upon the receiving hopper 22 and-a separator screen 23 is arranged within the chute 21 above the inclined bottom thereof and extends upwardly beneath the discharge opening in the hood wherebythe grain discharged therefrom is deposited upon the screen and moved downwardly thereon by gravity.

The receiving hopper 22 is provided with a vertical internal partition 23 dividing the interior of the hopper into the chambers 24 and 25. The lower edge of the separator screen 23 is extended over the top edge of the partition 23" whereby the clean grain is directed into the chamber 24 and is conducted therefrom through a laterally projecting discharge spout 26. The dirt and other foreign matter which falls through the separator screen 23 and moves down-- wardly upon the inclined bottom of the chute 21 is deposited in-the chambers and is conducted therefrom through the discharge spout 27. 7

What I claim is:

1. In a device of the character described, a receiving hood having a receiving opening therein, a plurality of inclined and staggeredly arranged bafi'les arranged in the v hood beneath the opening therein, hinge tilating shutters hingedly rods arranged in the hood groups of vensupported upon the rods in the opposite sides of the hood to control the passage of air therethrough, one

hinge rod at each group being extended and directed angularly, operating means connected with the angular terminals of the rods, and means connecting the opposite ends of the rods of each group whereby simultaneous adjustment of the several shutters of each group is affected.

2. In a device of the character described,

' a hood provided with ventilating openings,

hinge rods arranged transversely of the openings, opposed groups of shutters pivotally supported upon said rods and nor mally retained in closed position by gravity, one rod of each group being directed angularly, a flexible operating element having its terminals connected with the angular terminals of said rods, the opposite terminals of the rods of each group being directed op positely to, the first mentioned angular terminal, and means connecting the last mentioned angular terminals of the several rods of each group whereby the shutters of such group are simultaneously adjusted.

3. Ina device of the character described, a hood including front and rear Walls and provided with open sides and bottom, one

of said sides having a receiving opening in the upper portion thereof, hinge rods extending between'and maintaining the-front and rear walls in spaced parallel relation, and opposed groups of shutters carried by the rods and adapted, when closed, to lie in overlapping relation to form closures for the open sides of the hood. c

In testimony whereof, I afiix my signature hereto.

WILLARD PETTEYS.
