GRAIN-SEPARATOR.

Specification of Letters Patent.

PatentedlJan. 6, 1914.

of Lyon and State of Minnesota, havev inI vented certain new and useful Improvements in Grain-Separators; and We do declare the following to be a full, clear, and exact description of the invent-ion, such as will ena-'ble others skilled inthe art to which it appertains to make and use the same.

This invention relatesl to improvements in grain lseparators and particularly to means for separating wild oats from cultivated oats and other grain.

One object of the invention is to provide a machine of this character having an improved construction and arrangement of separating mechanism and improved means for removing the wild oats from the separating apron of the machine without injuring the apron.

A further object is to improve the separator shown in United States Patent No. 1,053,791 granted to us February 18, 1913 whereby this machine is rendered more etticient in operation.l

. With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts .as will be more fully described and claimed.

ln the accompanying drawings: Figure 1 is a side view of one side of our improved grain separator; Fig. 2 is a similar view of the opposite side; Fig. 3 is a front end view;

Fig. 4 is a rear end view; Fig. 5 is a central vertical longitudinal sectionof the. machine; Fig. 6 is a similar viewtalren on the line (3*6 of Fig. 3; Fig. 7 is `a top plan view of the machine wit-h the. feed hopper removed; Fig. 8 is a perspective view of the agitating frame for the separating apron.

Our improvedv grain separator comprises an apron supporting frame 1 consisting of parallel side bars 2 connected at their lower ends by a cross bar 3 which rests on the floor and supports this end of the frame. The opposite or upper ends of the frame 1 are secured to the upper ends of standards 4 which support the frame 1 at the proper inclination. The frame l is further connected to the standards 4 at their lower ends by inclinedvbrace bars 5 the upper ends of which project above the side bars 2 for a purpose hereinafter described. The side bars 2 of Application filed July 17, 1913. Serial N0. 779,577;

the frame 1 are connected intermediate their ends by crOss bars 6 to which is secured an inclined platform 7 lwhich supports the upvper stretch of the separating apron herelnafter described thus preventin this stretch of the apron from sagging or ecominguneven.

Revolubly mounted in suitable bearings on the upper ends of the standards 4 is an upper apron supporting and operating roller 8 a lower apron supporting roller 9 being revol'ubly mounted invsuitable bearings on the lnner sides ofthe side bars 2 near the lower end thereof as` shown. Engaged with the rollers 8 and -9 and adapted to travelaround the platform 7 is an endless separating apron 10 which is constructed of fabric having a nappy surface to which bearded grain such as wild oats will adhere. Fixed on one end of the shaft of the upper apron supportldrive shaft 14 is a combined crank Wheel Iand pulley 16 having a crank handle 17 ywhereby the same and the shaft 14 are revolved to move the apron 10 in the proper direction. 7

Secured tothe side bars 2 of the frame 1 and projecting above the same is a hopper supporting frame 18 in which is arranged a feed hopper 19 having an inclined bottom 20 and a rear side 21 which is adjustable to space the lower ,edge thereof a greater or less distance from the lower edge of the bottom whereby the width otA the discharge opening in the bottom of the hopper is regulated to permit'the grain to feed more or less rapidly from the hopper.

Loosely supported on the hopper frame 18 b v links or hangers 22 is a grain separating shoe 23 comprising lan upper inclined plate 24 and a lower inclined plate 25. The

plates

24 and 25 are spaced a suitable distance apart and secured at their ends to triangular end pieces having their apices disposed at the front end of the shoe whereby `the upper plate iriclines forwardly toward the lower plate and terminates at its lower edge a short distance from .the adja bil dll

a discharge space through which the grain passes from the upper plate onto the lower plate 25 which inclines rearwardly toward the separating apron and from which the grain is evenly distributed and discharged onto the separating apron. Secured to the lower cross bar at the front end of the shoe is a transversely disposed inclined tailings trough 26 which extends across the machine and is designed to receive the tailings -and coarse material which are caught by a screen 27 arranged on the shoe and spaced a suitble distance .above the upper plate 24 thereof and onto which the grain falls when discharged from the hopper. The grain passing through the screen falls onto the upper plate 24 of the shoe and slides down the same onto the lower plate and from this plate is discharged onto the separator apron as hereinbefore described.

The shoe'23 and screen 27 are agitated or kept continually in motion by a suitable shaking mechanism which preferably comprises a bell crank lever 28 which is ivoted on a bracket 29 secured to one of t e side bars of the apron supporting frame as shown. One end of the bell crank lever 28 has a pivotal connection with the rear cross bar 30 of the shoe 23 while the other arm of the lever is loosely connected by a linlr or operating rod 3l the forward end of which is loosely connected withV a wrist pin 32 which is arranged eccentrically on the driving pulley 33 of a blast fan hereinafter described3 said. pulley B3 being connected by a belt 34 with the main driving pulley lli hereinbelore described. 'lhe crank action of the wrist pin 32 will rock or oscillate the bell crank lever 28 which' in turn will shake, or agitate the shoe 23 thus lreeping the grain thereon in motion and causing the grain to pass down the upper and lower plates and screen thereoi' as will be readily understood.

Alrranged on the rea/r cross bar 30 of theA shoe are a series of grain agitating loops 35 which project upwardly through the discharge opening of the hopper and which are agitated by the movement of the shoe and thus prevent the grain in the hopper from becoming paclred and choking or clogging the discharge opening thereof.

Mounted ou the apron supporting frame l is lan casing 36 the discharge opening' of which is disposed immediately below the rear edge of the lower plate of the shoe so that the air blast created by the :tan 3'? which is revolubly mounted in said casing will be discharged. upon the grain as the latter falls from said lower plate 25 onto the separating apron, thus blowing out or removing the chad7 and light particles of foreign matter from the grain. rllhe fan 37 is lined on an operating' shat 38 revolubly mounted the ends of the fan casing and noemer on one end of each is fixed the drive pulley 33 hereinbefore described.

Arranged between the lower ends of the side bars 2 of the apron supporting frame is a lower grain separating shoe compris-4 ing a frame 39 on which is arranged a screen 40 and which is loosely supported near its forward end by short links or hang ers 41 which are connected to the inner side of the side bars 2.. At its rear end the frame 39 is connected by links 42 to the lower ends of short agitating levers 43 which are pivoted midway between their ends to the inner sides of the side bars 2. The levers 43 are pivotally connected at their lower ends to the right angular inwardly extending lower ends of pitman rods 44 the upper ends of one of which is loosely connected with the wrist pin 82 on the pulley 33. The pitman rod 44 on the opposite side of the machine is connected at its upper end to a wrist pin 45 eccentrically arranged. on a beater operating pulley 46 which is ixed on this end of the fan shaft and is thereby operated. By thus connecting the frame 39 of the lower shoe with the

pulleys

33 and 46 on the tan shaft said shoe will be agitated so that the grain discharged onto the screen 40 from the lower end of the apron will be nally cleaned and thoroughly separated from imperfect or inferior grain which will pass through the screen while the perlectfgrain will be discharged from the lower edge of the screen and may be caught by a conveyer or any suitable receptacle provided to receive the same. n

Arranged over the platform of the separating apron and below the upper stretch of the latter is an apron agitating frame comprising side bars 47 which are connectednear their upper and lower ends by cross rods 48, said rods being designed to strike against the inner faces of the upper stretch of the apron as the latter passes along over the platform thereby agitating or shalring'the upper stretch of the 'apron and keeping the grain thereon in motion. The side bars of the agitating frame are pivotally connected near their lower ends to the upper ends of the short agitating levers Ll-lwhile said'side bars 4'? are connected at their upper ends-by links 49 with supportin blocks 50 having ltherein longitudinal s ots 5l which receive clamping bolts 52 arranged in brackets 53 secured to the upper ends of the side bars 2 of the apron supporting'frame as shown. By sliding the blocks 50 upwardly or downwardly on the clamping bolts 52 the inclination of the linlrs 49 and levers 43 is corres ondingly varied and the apron agitating iiiaine will be raised or lowered thus bringing the same nearer to or farther from the upper .stretch of the apron which will cause said frame MOU ltd

n 50 in their adjusted positions for supporting the agitator frame at the desired elevation. By connectin the lower end of the `agitating frame w1th the agitating levers 43 it will be seen that when said levers are rockedl by the pitman rods 44, that the cross rods of the agitatin frame will be brought into and out of forci le engagement with the upper stretchof the apron7 thus keeping the latter v agitated and the grain thereon in motion.

The grain when discharged onto the apron in the manner described is carried downwardly thereby and all except the wild oats and bearded grain is discharged at theflower end of the apron onto the screen 40 of the lower separating shoe. The wild oats and other bearded grain will adhere to the rough surface lofthe conveyer apron and will be thereby carried around ,and back up on the lower stretch of the apron from the surface of which the vbearded grain hangs down and is supported by the -bearded ends thereof which have obtained a firm attachment with the roughened surface of the apron. In order to remove the bearded grain which has thus become attached to the apron We provide a rot-ary beater 55 comprising a supporting shaft 56 on which are fixed ra lally projectin arms 57 which are connected at their en s by beater bars 58. The bars 58 are secured to the ends of the arms 57j at a suitable angle for engaging and knocking the wild oats and other bearded grain from the lower-stretch of the apron asgthe grain is brought around in position to be engaged by the beater.

The' shaft56 of the beater is revolubly mounted in suitable bearing bars 59 connected to the standards 4 and side bars 21 of` the apron frame and on one end of the shaft 56 is fixed a small pulley 60 which is connected by a belt to the beater operating pulley 46 fixed on the adjacent end of the fan shaft as hreinbefore described. By thus connecting the beater with the fan shaft the movement of the latter will be imparted to the beater to revolve the same in the proper direction for removing the wild oats from the apron in the manner described and without injuring the latter.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring amore extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described our invention, what we claim is:

A grain separator comprising a supporting frame a separating apron operatively mounted therein, an apronagitating frame comprising side bars, rods connecting said bars and adapted to be brought into forcible engagement with lthe lower face of the upper stretch of the apron, levers pivotaly connected to the apron supporting frame and having a pivotal connection at their upper ends with .the side bars of said apron agitating frame, longitudinally slotted supporting blocks having an adjustable connection with said supporting frame, links connecting the upper ends of the apron agitating frame with said blocks whereby the upper end of the frame is adjustably supported with respect to the upper stretch of the apron.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
