cated improved means for feeding the ce-,

cal material to the improved cleaning and separating mechanism, which in turn feeds the same to a grading construction Without intermediate manual handling and with substantially automatic action.

One of the'features 015 the inventionconsists in the adjustable i eederinterposed be tween the hopper and the cleaning and separating mechanism.

Another feature of the invention consists "in the arrangement of the several parts and separatingmechanism and also the construc- 1 tion and adjustability ofthe same.

A further feature of the invention consists in the provision of a grading construction into which the cleaning and separating construction is adapted to discharge a part of the contents passingtherethrough.

One feature of the invention consists in the gei'ieral arrangement of the several indiv'idual mechanisms incorporated therein, wl'rereby the machine may be adjusted for various degrees of separation, dependent upon the cereals tobe separated from the cereal material supplied thereto and at a relatively high rate.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings, Fig. 1 is a side elevational view or a cereal cleaning, separating and grading machine embodying the features of the invention. Fig. 2 is a central sectional view of the machine showing the interior thereof. Fig.3 is an enlarged plan view showing a portion of one of the separating screens and the agitating means tlun'elor. Fig. l is a sectional View of the parts shown in Fig. 3 and is taken on the line 4 st of Fig. 2) and in the direction of the arrows. Fig. 5 is a sectional View of the parts shown in Figs. 3 and l and is taken on line 55 of Fig. 4; and in the direction of the arrows.

In the drawings indicates a plurality of upright standard members suitably supported by being provided with base mem tending plates or sides '19 and "-20.

termediate saidtransverse spacing members is an additionaltransverse member "I l. The

side trames'l ormed by thetransverse mem hers and the standards support 1n spacedie ration the-hopper, the cleaning andseparatin compartment including-the screens,"and

grading screens therein, all in superposed relation. In addition to the'foregoing compartments, the frame members suitably support/the suction ran 15 associated 'with the cleaning compartment and a second fan or blower 16 associated with the cleaning and grading screens. 7

:ln thcprescnt embodiment 'ot'the inventron the hopper compartment 17 -1s comprised o'l apair of side plates 18'su itably secured to the standards 10; Thesends of said hopper and'the base or bottonrare"coinposed of two inwardly and downwardly ex- The plate '20 terminates-short of theplate 1'9 and aperture 21 therebetween after passingthrough a feeding table 9. Interposed in said aperture and su'1ta'bly-secured to the plate -as by means of the hinges 23 is a closureplate 24 which is provided with agitating means.

The plate agitating means comprises a bracket plate'25 suitably secured, as in the present instance to the cleaning compart- .ent 22 so as to transnnt movement from the same to the closure member 24. fSecured to the outer side of the closure member is a pivot support 27 by which a connecting rod 28 is pivotally secured to said closure member. The rod 28 extends through the bracket plate '25 and carriesnpon its outer end a wing nut 29 "for 'adjustablysecuring the same'thereto- A suitable tension spring 30 is interposed between the outside "of the closure membe-rand the bracket plate 25, and in the present instance is concentric with and surrounds the rod 28'to maintain the closure plate in closed position as soon as released from the open -position'by the movement of the plate 25.

lit) thereof and-are received upon the table 9, which table is provided with suitable sides 8 and a backplate 7. By means of the bolt and wing nut constructions 6, the position of the table 9 can be adjusted to supply grain uniformly throughout the width of the compartment'22, whereas, due to any inclination of the floor, the table normally would discharge to one side of the, compartment. Said discharge therefor can be adjusted to secure uniformity of discharge by altering the inclination thereof through the bolt and wing nut constructions illustrated thus generally. An adjustable control plate 26 is also associated with the table and the amount of opening 26 determines Since the table 9 is carried by the compartment 22, it also will be agitated with the agitation of the compartment as hereinafter described.

In the drawings the cleaning compartment 22 is shown pivotally supported upon said frame by means ofa pair of links 31, see Fig. 1, pivoted upon the side wall 18 at 32 and pivoted to the compartment 22 at 33 to support said compartment upon the frame. The supporting brackets 34 suit-- ably supported upon the standards 10 and secured thereto, pivotally support at 35 a rocking lever 35. Said lever is pivotally and suitably connected tothe cleaning compartment casing 22 at 36. The rocking levers 35, as shown clearly in Fig. 1, support one end of the compartment while the other end is supported and suspended by the levers 31. In the present instance the pivot 36 upon each side of the compartment is suitably secured in a bracket 137, the same being rigidly secured to. an adjusting plate 138. The plate 138 is provided with a longitudinal slot 139 through which the pins 140 extend, said pinsbeing rigidly secured to the compartment wall 22 and being adjustably and rigidly secured in said slot 139 hymeans of the wing nuts 14 1. Thus, the angle at which the compartment 22 supported may be adjusted by means of the plate 138.

. When the lever 35 isrockcd by suitable means hereinafter to be described, the cleaning compartment as a whole is reciprocated. rocked or cradled, which in turn oscillates the closure memberor plate 24 through the rod 28 and about the hinges 23 as a center. and oscillates the feeding table positioned beneath the hopper. I

The means for rocking the lovers 35 comprises a large driving wheel 40 -mounted upon a stub shaft 41. suitably secured to the side frame, and in particular ,one of the transverse bars 12. As shown in Fig. 1, the stub shaft 41 is adjustably supported upon the machine by means of the rigidly mounted and arcuate supporting bracket 42; the latter being pivoted to the transverse member 12 at 43 and being adjustably and rigidcharge or exhaust conduit 57.

1y secured thereto at 44. by any suitable means. The driving wheel 4.0 is provided with a pulley portion 45 by which said wheel is turned. The driving wheel 40 is provided with a toothed periphery 4:7 and a sprocket chain 48 is driven thereby, which in turn drives a sprocket pinion 49 rigid with the shaft 50, see Fig. 2, suitably supported upon the framework. The sprocket pinion 49 carries the eccentric pin 51, which in turn supports the eccentric, crank arm, pitman or lever 52, the other end of which is connected tothe depending end ofthe lever 35. The shaft 50 extends entirely across the machine and upon each side of the same is positioned one of the. levers 52 which rocks the respective lever If desired, the power pulley 45 may be removed and replaced by a crank and eccentric so that the machine may be hand-operated,

lVithinthe cleaning compartment 22 is secured a plurality of cleaning members in spaced relation with each other and inclined at an angle to the. horizontal. The cleaning members are also offset from each other in such a manner that each succeeding member extends downwardly and beneath the upper or superposed member. In the present instance the cleaning members are so formed that the same are seatable one upon the other and may be readily removed from the compartment or from the remaining members. interchangeable. Furthermore, the members are readily detachable so that all that is necessary to separate the particular types of grainsor cereals from the general mixture, is to position in the compartment 22 the particular set of cleaning members. This will be readily understood for example when it is desired to separate from one mixture oats, and at another time to separate from the mixture wheat, the screens for each product will vary having the necessary requirements to secure the desired separation.

The conunirtment 22 supported previously described is provided with an inclined forward face 53. A chute member 5% communicates with the compartment 22 tl'nrougl'i an opening 55 at the free end thereof and is suitably secured thereto by means of the wing nuts 55. \Vithin the aperture is a second opening or aperture 56 which communicates with the suction blower or fan 15, the latter being provided with a dis- The fan Likewise, .the members are all.

filnithe present instance :a spring member 73 is:shown securedxto. ahook or adjustable bolt .74 which carries :a 'nut172 and :another .nut 72 The foregoing construction provides that :the :initial or normal :position of :the skeleton or teasing framework constructednasiatoresaid -can:b'e adjusted with respect :to;the iperforations 63 by means ol thebolt andanut construction ti l- 72 and 72. Also, the skeletonized teasing construction is thus yieldingly supported. adjacent saidperitorated plate/6O throughatheymedium.of the spring 73. If desired, .a plurality-of said springsi73;inay be substituted for the single :spring 73 .herein:illustrated without departing TflOHltllG broader feature of the invention. A closuresorbox 74- encloses the pro ecting ends ot thebolts T74. and throughthis meansthe position may beadjusted. This her: also provides a suitable receptacle "for tools-andthe likethatzmay be required for the machine.

, From the toregoing construction it will be understood-thatthe cleaning and separating compartment 22 isreciprocated by the lovers '35-an'd the individual screens 62 also recipro- .cated within said compartment, due to the motion of the same. 'FUT'tl'lQllUOlG, since each of the skeletonized teasing :mean's. adacent;each screening plate is .yieldingly attach-edto the reciprocating .wall otthe compartment 22, said teasing means will have a slightly independentreci-procatory motion upon said screening plate 62, and said ;re-

ciprocatory zmotion :may or may not be at As shown Asshown clearly in Figs-3 and' lptheperforations, which are grouped and an inclined and offset screening plate. The

V grains gradually work their way, due to the angle of the teasing means as illustrated in Fig. 4, beneath the strips 69, and then Work down beneath the same until they register with one of the openings 63, through which they drop upon the next succeeding screening plate, where the same operation is repeated. The teasing members by rubbing upon the individual grains clean and separate the same from portions of'the chaff, dirt and the like. The suction fan 58 separates this chaff and lighterdirt particles from the. grains during the operation of successive separations through the passage of the grains through the successive screens. i i

The screened and partially winnowed grain is collected from beneath the lower most screening plate, since the screening plate and the bottom of the compartment 22 are inclined at an angle to the horizontal. It will be remembered that the lower end of the compartment 22 has an aperture 46, and adjacent said aperture there is herein illustrated, see Fig. 2, inclined guide or deflecting plate 75, which discharges grain and the like into a hopper 76 therebenea-th. This hopper is formed by the side walls 77 the inclined receiving wall 7 8 and the hinged rear wall 79. The grain thus passes through the hopper by meansv of the aperture formed between the plates 78 and 79 on to a spring plate 81 positioned therebeneath. This plate directs the .grain from said plate to a winnowing plate 82. The winnowing plate is provided with flanges 83 by which the same is pivotally and. adjustably supported by the pins 84 secured to the side plates 77. Thus, the angle of thewinnowing plate may be adjusted as desired.

Positioned beneath an extension of the plate 81 is a plate 86. Said plates together with the extensions of the side plates 77, form a conduit which is adapted to discharge air under pressure adjacent the winnowing plate 82. the grains and the like which discharge upon the winnowing plate. Herein the fan 81 is shown adapted to provide the air blast, and as previoiiislyindicated, said tauis driven from the common source of power.

The separating and grading compartulent and this air passes through depending supporting lever '89 provided with a longitudinal slot 90 by which said lever is adjustably secured'to said pin by means of a wing nut 91. The other end of said lever is providedwith an'inwardly extending bracket in which is pivotally supported a pin 93 secured to said compartment. Thus a link arrangement similar to linkage 31-32-33 is secured. The opposite end of said compartment 87, see Fig. 1, is also pivotally supported by means of the pins 94 rotatable in suitable bracket means carried by the ends of the levers 35. Thus, when the pitman 52 is reciprocated by the means previously described, the compartment 87 will also be reciprocated simultaneously and in timed relation with the compartment 22. The speed at which the grains will pass through'the tilted compartment 87 is partially dependent upon the angle in which said compartment is adjustably se cured, as well as the rate of reciprocation.

Reference will now be had particularly to Fig. 2., The compartment 87 comprises a pair of spaced screens 96 and 97 said screens being of different mesh such that the first screen separates the larger sized grains from those of the middle and smaller sizes; while the second screen positioned beneath separatesthe middle sized grains from the smaller sized grains, the latter passing through both screens. The screen 96 discharges the larger sized grains into a receptacle 98, the same having an inclined bottom so as to discharge the grain collected therein to one side of the machine. larly, the receptacle 100is adapted to receive through the opening 102 the middle sized grains which have been separated by the screen 97. This receptacle is provided with an oppositely inclined bottom, so that it discharges the collected grain at the opposite side of the machine, but at the same end. The compartment 87 is also provided with a bottom plate 104, said platehaving an aperture 205 near the lower end thereof.

"lhrough this aperture all the grain which passes through the screens96 and 97 is discharged and. may be collected in a suitable receptacle positioned therebeneath.

In addition to the means for reciprocating the compartment 87 previously 'described, means are provided adjacent said compartment for agitating the grainspassin; therethrough. Said means is shown most clearly in F 1 and 2 and comprises a pair of bracket members 107 stationarily secured. to the frame. In each of said bracket members is pivotally supported the lever 108, the same carrying on one of its Simi-.

ends a beater or agitator bar member 109 means for causing said bar to move upwardly and engage or strike the bottom. plate 104 comprises a spring having an adjustable leased, due to the influence. of the springs 105 for striking a blow upon the bottom plate 10-1, thereby agitating the grains upon the screens contained within the compartment 87, is as follows: A shaft 114i extends transversely of the machine and is rotatably sup ported in bearings 115 suitably secured to the transverse bars 18. Upon the shaft 114 and rotatable therewith is'a' rotatable finger 117 for engaging the free and larger end of the lever 108, thereby elevating" this free end of the lever and depressing the opposite end in opposition to the" spring 105. Means for rotating the shaft 114: comprises a sprocket wheel, not shown, substantially similar to the sprocket wheel 49 and oppo sitely positioned upon the shaft 50. A chain or similarconstruction 120 rotates a sprocket gear 121 which is carried upon the shaft 114'. The operation of the machine has been simultaneously describedwith' the description of the parts thereof so that a resume" of the operation will sufiice to understand the same. The grain which is to be cleaned, winnowed, separated and graded is discharged into the hopper 17 and is discharged therefrom past the agitating closure at the base'of said hopper into the reciprocating, cleaning compartment. The "grain passes through the several superposed cleaning and separating screens by the action of the, teasing or agitating strips. The grain finally passes through all ofsaid' screens and collectsin the lower portion of the c1eaning compartment from whence it is discharged intoa winnowing hopper where the remainder of chatl, dirt and the like is removed from the clean grains. The clean grain is discharged from the the winnowing device into the grading compartment where it isseparated by suitable screening into a plurality of sizes, in the present instance three being shown. i

The machine as constructed simultaneously reciprocates the cleaning compartment and the grading compartment, as well actuates the agitating plate and bar adjacent the hopper discharging aperture and actu ates the heater bar adjacent the reciprocat- .ing grading compartment.
