To @Zlio/01net may concern.'

lle it known that I, Lammens K. Arluno, a citizen of the United lStat-ses, residing at Hope, in the county of Steele and State of North Dakota, have invented certain new and useful Improvements in VIild-@ats Separators, of which the following is a specifi cation.

My invention relates to separators and Vmore particularly to that class especially from the Suppol'n' body O1" frame' iA-Another object of my invention resides in the provision of an improved guarding means associated with theapron supporting body and with the upper portions 0f the apron to prevent the grain which is deposited upon the aprons from falling between the sides of the aprons and the inner walls of the supporting body.

A further object of-my invention resides in the provision of an improved means for mounting the screening means, the latter having novel means associated therewith for producing vibratory movement to the screens for agitating the grain deposited thereon, said movement beine imparted thereto simultaneously with the operation of the aprons, interposed between the screens.

A still further object of my invention resides in the provision of an improved fanning means mounted within the' body and arranged to convey chaff and wild oats that have not been separated from the good grain, by means of the agitating and separating means, to a point remote from the body.

A still further object of my invention resides in the provision of a device of the character described that is simple in construction, eilicient in operation and one that can be manufactured and placed on the market at a minimum cost. 1

Other objects as well as' the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this speciiication.

In the drawings:

Figure l is a side elevational view of my invention 5 Fig. 2 is a longitudinal sectional view of the same;

Fig. 3 is a transverse sectional view taken on the line 3 3 of Fig. 2 in the direction in which the arrow points; and

Fig. 4L is a transverse sectional view of my invention taken through the same at a point slightly above the lower screen.

Referring more particularly to the drawings in which similar reference numerals designate like or corresponding parts throughout the diiferent views, I provide a preferably rectangular supporting body or frame, including preferably side pieces l and end pieces 2, suitably connected and supported in spaced relation from the surface by means of legs 3, the forward legs being extended above the surface of the rearybraces 7 connected to the sides l of the body.

rlhe under surfaces of the hopper are slanted toward each other and are arranged in spaced relation with each other so as to allow grain to pass therethrough into the body. It is to be understood that this structure forms no essential parto-f the invention, being merely shown and described in this manner to facilitate a thorough understandingof the invention.

In order to screen the grain and also facilitate the separation of the chad from the `grain, I have disposed a screen 8 beneath the lower end of the hopper; this screen has its forward end secured to the sides of the body by suitable means, such as the rod 9. The screen is arranged in a closely spaced relation with the under surface of the top and has its opposite or lower end supported by means of rods 10. The looped ends 11 of these rods are connected to the sides of the screen by means of suitable fastening devices 12, which devices are adapted to operate, in slots 13 in the upper ends of the rear legs 3. The rods l() have their` oppo- `by the rods 10, and between the side pieces` l, is the lower screen 18. rlhe connection between the rods vand screen 18 consists of enlargements 14 through which pass suitable fasteniugdevices 15", the latter engaging the screen 18 and being arranged to operate in the slots 16 in the rear legs 3 for a purpose to be hereinafter described. The lower screen in this instance consists Yessentially of a rectangular frame 19, havving a reticulated means 20, preferably a screen wire disposed on the outer end ythereof, the outer end of the franie extending .slightly downwardlj7 and supported by ineans of a roller 21, rotatably mounted between tlie vforward legs. rIhe inner portions'of the sides of the frame 19 are extended vupwardly to provide supporting pieces 22 for maintaining the supporting frame 23 of the inner section 24 and screen 18, which section is incidentally formed preferably of wire screen of a iiiesh slightly.

smaller than the mesh of the screening l2O. The Vframe 23 is arranged in spaced parallel relation with the frame :19 and abuts a be hereinafter described, and vwhich guard y.has its lupper end arranged .in spaced relation with the rear end 2 and yupper edge also in spaced relation with .the said end 2, the lower end of the guard being` supported upon and rigidly connected to the inner end ofthe frame 19.

A pain 26 is supported in spaced relation on the under surface of the frame 23'.to refceive the good grain after it has passed through vthe screen 24, the said pan having an opening 27 therein adjacent the outer end thereof and to the under surface of which pan about the opening is connected a chute 28'by means of fastening devices 29, the said chute serving as a suitable means Vforcoiiveying the good grain from the pan to a receptacle positioned beneath or at a point reinote from the supportingY body or frame. Another pan 30 is rigidly supported on the under surface ofthe outer end of l.the fraine 19 for receiving vthe good grain which .is incidentally better than the grain thateiiters the pan 26 .for-the reason that tlieinesh of the screening' 2O is larger than that of the screening 24 carried by the frame .23.V The can 30 Ais also :provided with an opening 31 whichallows the grain to enter the chute 32 carried on the under surface -ofthe pan 30 about the opening, thesaid chute facilitating ithe conveying fof the grain to a. receptacle beneath lthe frame.

For the purpose of separating` wild oats 'drum 35 having one of its ends projecting through one of the sides of the body and on which reduced end is rigidly connected a cog wheel 37 for a purpose to be hereinafter described. The lower apron 34 is slightly longer than the upper apron and operates about drums 38 and39, the druin 38 having one of its ends reduced and journaled through the sides 2 to receive a cog wheel 40 which incidentally is arranged in mesh with the cog wheel 37 and operable thereby. In order to provide an eflicient means for governing and adjusting the tension of the separat- ing aprons 33 and 34, I have found it expedient to journal the ends of the rear drunis 36 and 39 in blocks 41. These blocks are slidably mounted in 'openings 42 that are formed in the sidesand iear legs of the body. The free ends of bolts 43 are rotatalbly secured inthe blocks to provide for a more or less universalV movement therebetween'. The upper one of said bolts .being also arranged, preferably in screw threaded engagement, with the laterally extending brackets 44 carried on the sides of the rear V'legs adjacent the upper ends thereof. The

lower one of the bolts being arranged through the rear edges of the rear legs. The heads 45, 'f orined on the opposite ends of the bolts, constitute a suitable ,means for rotatingtlie bolts and causing the blocks to slide in` either direction in the openings 42 to adjust the tension of the aprons.

Transverscbars 42 extend between each of the aprons and serve as a suitable `means for 'facilitating the supporting of the upper portions of the aprons when heavily laden with grain, thus facilitating the operationV ofthe aprons.

InV order` to prevent the grain that has been deposited upon the aprons from falling .between the side edges of the aprons and the inner sides Vof the body, I have rigidly secured guarding strips 46 to the inner surface of the sides 1 lby means of suitable fastening devices 4:7. the side strips extending laterally froni'the inner surface of thesides and bei-ng arranged `in close relation with the upper surfaces ofthe aprons.

.In order to remove wild oats ,from the separating aprons to which the wild oats adheres during the operation of the aprons, I Vhave extended scraping bars 48 ytransversely of the body, the respective ends thereof being secured to theinneisides of the body, `and vthe upper edges of the bars being arranged in close engagement with theiend portions of the aPIQIlS; the bars being disposed at acute angles to the ylower CIK the bars facilitates the removal of the chad and wild oats from the aprons as well as the depositing of the chaff and the wild oats in the chutes 49 positioned beneath each of the and arranged transversely of the body, the said chutes being also arranged slantingly toward the lower screen so that the wild oats will slide down the saine and be conveyed toward the lower ends due to the force of gravity, the said lower ends beg positioned exteriorly of one of the sides so that the wild oats may be deposited in a suitable receptacle positioned therebeneath.

ln the event that all of the chaff and wild oats are not removed from the grain after the latter has been deposited upon the lower of the screens in a manner to be hereinafter described, I have provided my improved farming means for conveying the chaff from the lower screen to a point remote from the body. Theffanning means in this instance consists of a transversely arranged and rotatably mounted shaft 50 on which is rigidly carried a sleeve, on the outer surface of which is a `plurality of radially projecting blades 51. lt isfpreferable that the blades of this fan extend approximately entirely across the body so as to provide an efi'icient operation, or rather means for expeditiously removing the chaE and wild oats.v When the fan is rotated in a manner to be hereinafter described, a draft is created across the bottom screen through the medium of the opening provided in the rear end by the guard 25. The fan is positioned approximately midway between the lower apron 34 and the curved forward end plate 5'2 and is arranged to rotate so that the blades adjacent the curved plate move upwardly with respect thereto thus causing the chalf and wild oats to be drawn from the lower screen and conveyed about the curved plate from whence it is blown upwardly and out the opening provided in the upper end of the body between the topv and the forward end of the body. It is of course understood that if desired, means can be employed for conveying this chaff and wild oats to any desired point should it be found necessary.

ln order to simultaneously operate the aprons in opposite directions and agitate the upper and lower screens as well as actuate the fanning means for agit-ating and separating the grain that is received from the hopper 5, I have journaled the respective ends of the transverse shaftv 5S through the forward legs adjacent the upper ends thereof at a point in substantial alineinent with the upper of the aprons, the said shaft having a large gear 5^: rigidly carried by the projecting end thereof, which gear is positioned in close relation with the exterior of one of the forward end pieces and l arranged in mesh with the gear wheel 3 Also rigidly connected to this shaft 53 is a cog wheel 55 and handle 5G, the handle facilitating the rotation of the shaft consequently rotating the gea i' as well as the gears 37 and 4Q il chain 57 is trained about the cog wheel and also trained about another cog wheel 58 i Cfdly carried on the projecting end of the transi se shaft 53 is rotated, the shaft consequently causing the fan rif/idly carried by the shaft 50 to be rotated roi' accompli-slung` its function. A connecting rod 59 having its respective looped ends bivotally connected ecceiitrically to the outer surface of the cog wheel 58 and one of the disks 16 throuoh the instrumentalit of the fasten- .c v l L Y ing device 1o constitutes a suitable means for imparting a shaking or vibrator-y mover ent to the screens. T his movement is facili-cater through the medium of the openings provided in the rear legs, Jror it will be seen that when the crank 56 is actuated, the bars 11 :jr

will move substantially vertically causing the screens 8 and 1S to which they are connected to consequently more up and down, which screen 18, because of its connection with the rods at the openings 16 will move slightly longitudinally of the body, the roller 21 lfaeilitedting the supporting' of the frame of the screen 20, during this sliding movement. As the screen 8 is agitated,

grain will be deposited upon the upper of i the separating aprons 35, said grain being prevented from falling therefrom about the sides thereof by the strips d6. rlhe upper apron 33 will move in the direction in 'which the arrow points towardV the forward end i of the body, consequently causing the grain thereon to be deposited upon the lower apron and the chaff and wild oats which adheres to the upper apron will be scraped therefrom and deposited in the chute a9 and conveyed from the body. After the grain is deposited upon the lower apron 34C it is carried to the rear end of the body and deposited upon the screen 24. Vild oats will adhere to the apron 34h and be conveyed en the under portion until it engages the other of the scraping bars 48 and deposited in the other of the chutes i-9 and thence conveyed from the body into a suitable container, not shown. Due to the vibratory movement of the said screen, som-e of the smaller kernels of grain fall therefrom and rest upon the pan 26 positioned therebeneath from whence kernels of lgrain fall through the chute 28 into a suitable receptacle, not shown, positioned beneath the body. rlhe larger kernels of grain sli le from the screen 24 and fall upon the screen 20 of a larger mesh, from which screen the kernels fall between the pan 30 and thence pass through.

able source of power, not shown, may be associated therewith so as to actuate the separatoi.

Although I have shown and described the preferred embodiment of my invention, I

desire vthat great stress be laid upon the arrangement of the cooperating screening,

- separating and fanning means for eficiently separating wild oats from grain, the said screening means being` peculiarly arranged to assort or gra-de the grain after it has beenv cleaned. Attention is also directed to the novel means for simultaneously operating the screening, separating and fanning meclianisni.

yFrom the above description taken in connection with the accompanying drawings, it can easily be seen that l have provided a device that is simple in construction, containing but a few simple parts that can be cheaply manufactured and assembled and when assembled can be placed upon the market and sold at a minimum cost..

t will be understood that the above description and accompanying drawings compreliendonly the general embodiment of my invention and that Vvarious minor changes in detail of construction, proportion and y arrangementV of the parts may be made with- ,in the scope ofthe appended claims and without sacrificing anyof the advantages ofV my invention.

Having thus fully described my invention, what l claim as new and desire to secure by r Letters Patent, .is

A'wild oats separator. including a body,

yupper and lower screens mounted in the body, a plurality of separating aprons operating in opposite directionsV interposed between the screens, means for preventing grain from falling about the sides of the aprons, means forremoving the wildV oats from the aprons, means for operatingvthe apronsand simultaneously imparting a vibratory movement to the screens, and means for conveying the cleaned grain.l from the body. f
