1
I claim:1. In a grain separator, conveyer belts arranged in proximity to each other and coacting to· carry grain between them, to pro- 75 ject the same into a separating chamber means for driving the belts in unison and at uniform speed, a converging grain guide in position to receive grain from the belts,, a separating chamber into which the grain 80 guide discharges, an air supplying means, at the opposite end of the said separating chamber for forcing air against the grain entering the separating chamber, a plurality of spaced grain collecting means at the bot- 83 tom of the said separating chamber and discharge chutes connected with pairs of the grain collecting means, substantially as described.
2
In a grain separator, means for fore- 90 ing grain through a converging chute which terminates in the open end of a separating chamber, means for forcing air in a direction approximately opposite the small end of the chute and toward the open end of the 95 separating chamber, collectors at different distances from the means for delivering grain into the separating chamber and means therein which individually will receive grain of different specific gravity, and 100 guards over the collectors for preventing agitation of grain in its descent to the collectors.
3
In a grain separator, conveyer belts arranged in proximity to each other on dif- 105 ferent planes and coacting to carry grain between them, means for driving the belt in unison and at uniform speed, a separating chamber into the upper portion of which the grain is projected by the conveyer belts, 110 means for delivering air under pressure to the separating chamber in a direction opposite that traversed by the grain delivered to the separating chamber, and a sectional bottom in the chamber the sections of which 115 are at different distances from the grain delivery section of the separating chamber for collecting grain of different specific t gravity, the discharge end of ‘he means for projecting the grain into the separating - 20 chamber and the discharge end of the air blast conduit being in line with one another and above the means for collecting the grain projected into the separating chamber.
4
In a grain separator, a hopper for receiving grain located above a pair of rotary carriers, a way having a portion- of its open larger end opposite the carrier belts, said way converging from its receiving end 130 A compressor or blower 23 is conventionally shown and is employed for the purpose of delivering air under pressure to the separating chamber 21 through means of a pipe 5 24. The pipe may have a suitable gate 25 by which the passage through the pipe may be restricted to regulate the air to be delivered to the separating chamber. The pipe 24 preferably enters the separating chamber 10 at an otherwise closed end near the top thereof and the opposite end of the chamber 21 is open and receives near its top wall the grain guide or chute 20 in order that the open end of the chute will be in line with the 13 discharge end of the blower which will force air against the grain and chaff entering the separating chamber, as has been described. The bottom of the separating chamber has a plurality of oppositely inclined walls -Ο 26 and 27 intended to collect grain at different localities as to the length of the separating chamber, it being understood that heavy grain will be propelled to a greater distance against the action of the air blast 23 than the lighter grain, and hence the heavier or perfect grain will be received by the hopper that is farthest from the chute 20 and directed therefrom through openings 28 in the bottom of the separating chamber 30 to the spout 29, from which the grain may be bagged or collected, as is ordinarilv done with devices of this kind. The lighter grain will, of course, not have the velocity of the heavier grain and it wil be arrested 35 by the air blast so that it will be arrested by the baffles 27 a and be diverted thereby into the hoppers and pass through openings 30 in the bottom of the separating chamber, from whence it will reach the spout 31 for 40 collection. The end of the separating chamber opposite the air pipe and below the end of the chute 20 is open and chaff, straw and light materials will be forced from the open end 45 thereof in order that the grain that has been collected will be clean and free of such chaff. Any suitable means may, of course, be employed for driving the power shaft and the inventor does not wish to be limited 59 with respect to these features. Figure 1 shows appropriate belting for operating the mechanism from the power shaft, but the inventor does not wish to be limited with respect to the details of construction in this 53 regard, In order to direct grain that is descending in the separating chamber toward the bottom thereof, a series of transverse and vertically disposed plates 27 a are arranged 99 between the two side members 27 b constituting a frame which may be applied to the interior of the separating chamber, and this frame may be supported by the inclined sides of the hoppers 26 and 27. These ver35 tically disposed plates 27 a will serve to pre1,568,618 3 to its discharging end, a separating chamber which is open at the end into which the way extends, a blast fan, means for projecting a blast of air into the aforesaid open 5 ended chamber and toward the open end of the way, means for receiving grain of different densities which extend partially up ward in the separating chamber providing a plurality of compartments, pairs of said compartments having eduction openings for the grain, and chutes underlying said eduction openings whereby grain of different specific gravity may be separated.

'J'o aU whom'it may concern: ,.

Be it known that 1, Henry Ernest Peori;. a cilizen of the Dominion of Canada, and i evident of , Hamberg,, . .in the county of 5 Wells’and'State of North Dakota, have invented certain new and useful Improvements in Grain Cleaners, of which the following is a specification. , .. , , This invention relates to grain cleaners 10 and separators, and has for an object the provision of novel means for removing chaff, straw and the like from, grain and 'fbr grailitfg the ‘grain · according fo its. . specific gravity in. order that the .pterfect 1® grain such as may be used 101^ feeding and the like can be separated from the less perfect or lighter grain: novel means being also provided for collecting the grain of different grades in separate receptacles.

20 pt ΐΡ a further object of this invention to produce an apparatus in which grain in an ’Ungraded state is forced with considerable velocity against an air blast effective to impede or retard the movement of the grain in 25 order that the heavier grain will travel further agiiinst the action of the air current fli;i:n the lighter grain; and the iriyehtibn also contemplates the production of hn ap• ' '.parat Us ’in which. the, air blast will serve to 30 fo ree stfaiv 1 arid chaff away from the grain •prior to the collection of the grain in the inaniier stated. . .

With the foregoing and other objects in , vifiw, the invention consists in the details of 35 (cnstriiction, and in the arrangement and combinafioii of parts to Bie hereinafter more fully set forth and claimed.

In describing the invention in. detail, reference will be had to the accompanying 40 drawings forming part of this application wherein like chaiacters denote corresponding parts hi the several views, and in which-— .

Figure 1 illustrates a view in elevation of a grain cleaning and separating device 45 embodting the invention;

Figure 2 illustrates a longitudinal sectitinal view thereof; ,. ..-./

Figure 3 illustrates a /ritew in elevation of one end of the appar&f tfs; , .

Figure 5 illustrates a detail view of the ; ii· pipe control.. . , ,, ...,,,. ...: .......

In these drawings, any suitable frame const riiciion lii miy be employed having means for hdppoiting the operating parts of the apparatus, and h delivery chute 11 is provid,e(l,’.thiObgli’which the grain to be cleaned ;is dclivered.tb' a hopper 12, the said hopper liax ing a sliding d'obr 13by which the escape of grain therefrom may Be regulated, as will beapparent; '. , . A conveyer Helt 14 is iiiounted on drums pr rdllefS 1'5 and lti oh a plane below the dis: bulge oji'enihg of the hopper, and the drum 15 islbteated; back or rearwardly of the discharge ojien ing in order that the conveyer Helt may operate tinder the discharge opening arid*receive, grain issuing froin the hopper. The conveyer Belt 14 coacts with a belt 17 mounted on drums or pulleys 18 and 19 located above the belt 14, but the belts 14 arid 17 are. in such relation to each other that they will serve tb receive grain between them arid ,pr!ess on the grain with sufficient force to Chrry it from the hopper to a. horizbritElly riiaintained grain guide or chute 20, which converges from its receiving end to its discharge end and through which the grain is forced‘f0 a separating chamber 21. The grain -guide 20 preferably tenters the larger open end of the chamber at the end anti near the top thereof and the guide is preferably tapered from its grain receiving end to its discharge tend, its upper Avail converging toward the other tend of the chainber 21 a Condition which serves to restrict the actioh;bf the air blast prior;tb the,entrance cif gr'diri into the separating chamber.

The drums or pulleys 15,. 16, 18 and 19 'are, mounted bh suitable, shafts provided with suitaEle beltihg fbr operating the conveyer belts rapidly in order that the grain will be forced, from . the cimyeyer. with con’s iderable vrilacity p'roportional to the type of grain being cleaned and the velocity of the air blast, as one skilled ill tfie. art will undersfand. The gearing or belting for operating the pulleys from a drive shaft is conventionally shown and identified by the, letter A. it being also shown that a belt B operates over a pullev 6 on a shaft. D for driving a blower or compressor. as will presently appear. A crossed belt, see Fig. 3, drives pulleys on the shafts/having drums for the conveyer belt 14 and 17 in order that they av,ill travel in the same direction and at the same speed.
