GRAIN CLEANER, SEPARAT'OR, AND DRIER.

To allwhom it may concern:

Be it known that I, VILLARD A PETTEYS, a citizen of the United States, residing at Wilcox,in the county of Kearney, State of Nebraska, have invented a new and useful Grain Cleaner. Separator, and Drier; and I do hereby declare the followingto be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved machine for screening, separating and dry ing grain, as wheat and corn and other grains and one of the objects of the invention s to provide a machine of this kind especially adapted for use in connection with grain elevators.

A further object of the invention is to pro-"" Vide a trough member provided with a plurality of screens of different mesh, each'being inclined relative to the trough, and arranged and the amount of air to be permitted to circulate through the grain during the screening and separating process and also to catch and convey the dockage that drops through the screens into a receptacle at the lower end of the trough.

A further object of the invention is the the provision of means for supporting screening trough, whereby the inclination of the trough may be varied for facilitating the screening, separating and drying of the grain.

In practical fields the details of constructionmay necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination ofparts as hereinafter set forth shown inthe drawingsand claimed.

In-the drawings Figure 1 is a view in side'elevation of the V bolts 21 extend.

improved screening and separating machine constructed in accordance with the invention.

Fig. 2 1s a plan view.

Specification of Letters Patent. P te ted Nov. 29, 1921. Application filed June 4, 1918. Serial No. 238,155.

Fig. 41 is a sectional view on line 4-4: of Fig.

F 1g. 5 1s an enlarged, fragmentary, sectional view of the discharge end of the.

trough or chute.

Referring more especially to the drawings, 1. designates an elongated trough shaped chute or member comprising the sides 2 and 3. The upper portions of the sides 2 and 3 are connected and braced by transverse channel bars 41, through which the bolts 5 extend.

On the'outer faces of the sides are vertical reinforcing bars 6, through which the'bolts 5 also extend, said bolts having nuts, for drawing the parts together and reinforcing the sides of the trough shaped chute. These bars have additional securing means such as screws 7. Secured to the inner faces of the sides are a series of opposed angle bars, 8, 9,

10, 11, 12 and 13, 14, 15 and 16, which are arrangedin stepped relation and overlying each other, thereby providing guides for two series of screen members, designated 17 and 18. These s'creenmembers consist of upper and lower frames, which are rectangular,

and provided with wire fabric material 19 or perforated metal which is secured to said frames in any suitable manner. The mesh of the wire fabric of the members 17 is larger than the mesh of the wire or metal fabric of the members 18, which may be removed, for the purpose of screeningcorn and the like. In fact by providing the'upper and lower screens with finer and coarser mesh, grain may be separated according to various sizes. The angle bars are inclined withv relation to the trough shaped chute, in order to hold the screen members inclined as shown. By disposing the trough shaped member on an inclination and owing to the stepped relation of the screen members, the grain may pass from one screen member to the other. The screen members may be re movedfrom their guides (in which they are frictionally held) by sliding the screening members in the directions of the arrow at.

The angle bars forming the guides for the screenlng members are secured tothe inner faces of the sides of the trough shaped chute "by means of screws or the like 20. However, through certain of said angle bars rod Pivoted upon the bolts 21 at the opposite ends of the trough shaped chute are bail shaped men Surrounding the rod bolts v21are sleeves 22 which are interposed between certain opposite angle bars.

bers 23, which are provided with eyes 2 1, in

which are secured the ends of ropes or cables 25. By means of these ropes or; cables and 26 the trough .shaped chute or screening machine may be supported on anyf desired grain elevator (not inclination from a v shown) to any one of a plurality oi' bins (not shown), so that-various grains when dumped into the hopperi27 may pass through a screening process during the passage to the bins. The cableior re e25 as well as the rope or cable26 may be adjusted, to alter the inclination of the screening machine-or trough shaped chute. Suitable open frames 28 are lunged at 29 to the side 3 of the chute. These frames 28 are interposed be- 7 tween the channel bars 4. there being flanges 3O onthe channel bars to support the 28 when closed.

by the longitudinal strips 34, which are secured to the lower edgesof the sides 2 and 3' by means of suitable screws 35; The shafts 33 are provided with shutters 36 which are as shown inarranged to overlap each other Fig. 3..

The shafts 33 adjacent one of the sides of the chute are providedw1th right angle extendin arms 38 and 89. The arms 38 of the.

b 7 lower series of shafts have ivoted thercto I a connectlng bar 40. A connectlng bar 41 1s pivoted to the ends of the arms 39' of the upper series of shafts. Certain of thearms 38' and 39 respectively are extended to pro-- vide le'vers42 and 4-3, which havehandles 44c.

Se ment racks as are secured on the outer face of the side 2 of the trough shaped chute,

' whereby the'teeth of which may be engaged by the ribs 46 of said levers, to'hold the levers in different adjusted positions. alt is to be observed that the lower series of shutters maybe opened ind pendently of'theupper seriesand vice versa. By openin both series of shutters a current of air is'allowed to pass through the chute throughout its, entire length, and it is apparent that upon opening either one of theseries of shutters, a current ofairis allowed topass throughonly a portion of the chute. In the operation the ma--' chine isytilted, substantially on a forty five degree inclination whereby its hopper end will become positioned under an elevator spout (not shown) of an elevator drive way, and the lower end may be disposed to discharge or dump into suitable bin (not shown). Such a bin may comprise compartframes hese frames'28 are cov eredby pieces of wire fabric or mesh work S1, to prevent the grain when passing from a one screening member 17 to the next'screendrying" the grain as it passes through the chute, and also blows the chaffand dust, dirt and like'from thesame; The pounding and rubbing thatthe grain is subjected to as 1t rushes through the machine, at the same time the air cleans, scours and dries it assists inremovimg the chaff or other particles from the grain. The chaiiis 'forcedout and the weed seed and shrunken kernels, usually called doclrage are separated. I This dockage is worthless and when retained at the elevator establishmentthe freight-is saved which has been he'retofore paid on shipping thesame, andthe dockage so retained maybe sold as screenings. The grain thuscleaned raisedthe grade of the grain, andconsequently commands higher price; Gravitationdraws the grain :through the machine and if greater or less'speed in the screening of the grain is-required either end o-fthe machine maybe raised or lowered. 'Qne of the shutters 36 such as indicated at amay bore moved, for'lea'ving a space. This'space when the shutter as mdlcated at a is removed allows the dockage to pass therethrough into a receptacle (not shown). This'space will also permit a current ofair to pass through the chute for cleaning the grain; However,

when this space is closed by the shutter as indicated'at'a the grain or the like is conveyed'to the lowerend'of the chute, fordischarging into asecond' receptacle. 3

Theinventionhaving been set forth what is claimed as new and useful is 1. In a grain separating structure comprising a trough shaped rectangular chute, upper andlower spaced series of screening members, each of said screening'members' having upper and lower parallel-inclined guides secured to the inner sides of the chute, screening frames of different mesh supported by the said guides, an upper and lower independent series of hinged shutters constituting a flooring for the chute and baffie plates-for the upper and lower series of screening members,"and independent means to selectivelyopen either seriesofshutters to regulate the airdraft-within the chute. i 2. A'grain separating structure comprising a reotangular'itrough, upper and lower spacedYscreen-ing members in said trough, each of said screening. members havin incl'i-ned,.overlapping guides fixed-to the inner 130 sides of said trough, frames provided with wire mesh of different size supported by said guides, an upper and lower series of independently hinged shutters constituting a flooring for the chute and baffle plates for the upper and lower series of screening members, transverse rock shafts for selectively operating and angling either series of said shutters to regulate the air draft within the upper or lower portion of the chute, segmental racks and vertical arms extending from said rock shaft for engagement with said rack whereby the said shutters may be maintained in their predetermined position.

3. A grain separating structure comprising a chute, upper and lower spaced screening members within said chute, hinged open frames above said screening members, each of said screening members having overlapping, parallel inclined guides secured to the inner sides of said chute, wire frames of different mesh supported by said guides, an

upper and lower series of independently hinged shutters constituting a flooring for the chute and baffle plates for the upper and lower series of screening members, rock shafts for selectively operating and angling either series of said shutters to a predetermined degree to regulate the air draft within the upper or lower portion of the chute, segmental racks on one side of said trough, vertical arms extending from said rock shaft for engagement with said racks whereby the shutters may be maintained in their angular set position and flexible means for supporting the ends of the chute in its inclined, operative position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
