SPECIFICATION forming part ofvLetters Patent No. 322,548, dated July 21, 1885.

Application filed February 24, 1883. (No model.)

Zo @ZZ whom it may concern:

Be it known that I, JOHN LUoAs, a citizen of the United States, residing at Hastings, in the county of Dakota and State of Minnesota, have invented a new and useful Wheat, Oat, and Oockle Separator, of which the following is a specification.

This invention relates to wheat, oat, and cockle separators, and it consists in the novel construction and combination of parts, which will be first fully described, and then pointed out in the claims.

In the drawings, Figure I is a perspective, and Fig. 2 a vertical longitudinal section, of my machine. Fig. 3 is a detail view of one of the slides. Fig. 4 is a detail view of the elevator. Fig. 5 is a detail view of the end spout, Fig. 6 is a detail view of the lower supplemental sieve. Fig. 7 is a detached sectional View of the main sieve and the endless slotted apron. Fig. S is a detail perspective View of the hopper and main sieve. Fig. 9 is a detail view of the slide-sections. Fig. 10 is a detail view of the upper supplemental sieve. Fig. Il is a detail view of the side spout, all of which will be described.

The supporting-frame of my machine is formed of the inclined side boards, AA, supported by their upper forward ends by legs B, which are slotted vertically at b, and secured to the side frames by set-screws b', passed through said slots, so the side boards can be adjusted vertically to Vary their inclination. Legs C C support the lower end of theiside boards, and an end board, C', extends between and-connects said legs C. The side boards are' provided in their upper ends with bearingslots D, and in their lower ends with slots D', and the main sieve E is secured between said side boards, below the slots DD', and at an inoline, as shown. The hopper F is arranged at the upper end of the machine and provided with an agitating-roller, f, having an end pulley, f', and with a discharge-opening, F'. A tilting board, G, is pivoted at its forward edge in advance of the opening F', and eX- tended under and beyond said opening, with its rear edge over the upper end of the main sieve, as shown. This board G is provided at or near its tilting edge with a springarm, G', which extends alongside of the hopper and engages the teeth of a rack, F2, so that the tilting board may be held at any desired inclination for the purpose of regulating the outmental77 sieve.

flow of the grain. The endlessl apron H is provided with cross-slats H', and is supported on rollers I I'. The roller I has its trunnions supported in slots D, and provided on one end with a pulley, t', and on its other end with a hand-crank, i', and a pulley, t2. The pulley ft2 is geared by belt '3 with pulley f', and thus operates the agitator f, as will be understood. The roller I' has its trunnions projected through slots D' and journaled in plates J, which are adj ustably secured to the side boards, A, by set-screws J', passed through slots j, so that the apron may be tightened when desired. This belt is moved in the direction indicated by the arrow in Figs. I and 2, and feeds the grain down on the main sieve. A sieve, K, is arranged below the upper end of the main sieve and extended slightly below the middle part of said main si'eve, as shown. I preferably pivot this sieve midway its ends, so it may be adjusted to any desired angle, and it may be held at the desired angle by fitting it to lbind between the side boards, A, or by set-screws, or other similar expedients, as desired. I also prefer to form this sieve with tw`o screens, one above the other, as.shown most clearly in Fig. 2. The spout L is arranged at the side of the machine, below the side boards, A, and slightly nearer the lower than the upper end' of the machine. Inclined grooves M' are formed in the inner sides of the boards A A, between the spout and the sieves K, and extend downwardv below the rear side of the spout and upward to a point about midway the ends of the sieve K. A cutoif board, M, is supported and movable in these grooves above the spout L, and between the latter and the sieve K. By adjusting this cut-off to the position shown in Fig. 3 it will out off the grain screened by the lower half of sieve K from spout L, and deliver sameinto the end spout, presently described. By adjusting this cut-off M in its grooves, the grain screened bythe lower part of sieve K may be delivered into either the side or end spout, asY desired. The sieve K, I denominate, for purposes of reference,theupper supplemental77 sieve, and the sieve N, the "lower supple- This latter sieve is arranged below the sieve K, and has its lower end projected slightly over the side spout and its upper end extended to a line below the forward end of sieve K. This sieve is also preferably pivoted midway its ends for purposes of ad- ICO justment, and may be held in any desired position in a manner similar to that described with reference to the sieve K. A narrow board, O, is arranged at an incline between the the sliding cut-offs P P. The upper groove,

P', is extended nearly to the lower end of the upper vsupplemental sieve, and either or both the cut-oifs P may be adjusted in their grooves to throw the screenings from the lower part of the main sieve over the end board or into the end spout. This endV spout, Q, discharges through an opening, C2, in end board, (Y, and thence through an opening, R', into the case of the elevator R. This elevator is arranged at the discharge end of the machine, and is provided with an endless carrying-belt, R, supported on rollers R3 R3, the upper one of which is provided with a pulley geared by beltS with pulley t' on roller I. The grain, tailings, Svc., delivered through opening R is taken up by the elevator and deposited by spout It* onto the apron, by which itis carried upward and redelivered onto the main sieve. The elevator may be supported at its lower end by a foot-board, T, which rests on the iioor and may be screwed to the end board, C. This foot-board holds the elevator away from the end board, C', andits upper end is inclined so as to throw the dbris, tc., delivered over the end of the machine to opposite sides. The upper end of the elevator is braced by vthe stay-rods U U, as shown. The cut-offs P P and M, it will be understood, may be held at any point of adjustment by fitting them sut'- ciently tight in the grooves P M to hold them from any movement except when positively actuated, as will be seen.

In operation motion is given by crank t', and the grain passes out of the hopper and is carried by apron H down over the sieve E.

The unhulled grain, dbris, te., which fails 4to pass through sieve E is deposited at the end ofthe machine onto the floor or ground, where it may be collected and disposed of as desirable., The grain passed through the upper part of sieve E' passes onto sieve K, and is screened through the same or passes off its lower end onto cut-off M, and thence into the end spout. By adjusting the said cut-off downward the grain screened by the lower part of the sieve K may be delivered into the end spout, or the said board M may be set farther downward in its grooves so it will catch but a small quantity of grain screened by sieve K, the major part falling onto sieve N, and thence into the side spout, as will be seen. The grain passes down sieve N, by which any fine dust or dirt is separated from it, and into the side spout, out of which it flows in proper condition for bagging. The main sieve is coarser than the upper supplemental sieve, and the latter is coarser than the lower supplemental sieve, so the screened matter is reduced in quantity as it flows through the machine. The matter which is thrown off from the sieve E is cast out of the machine, and the other matter, except that which has been properly separated, is redelivered into the main sieve, and again run through the machine.

In starting the machine the tilting board is adjusted to permit a vfull feeding, and as the elevator begins to deliver the grain onto the apron the feed from the hopper is limited according to the quantity brought up by the elevator, in order that the quantity of stuff running through the machine may not exceed its capacity.

The supplemental sieves may be adjusted on their pivots to various angles, according to the quantity of grain passing through the machine.

Having thus described my invention, what' I claim, and desire to secure by Letters Patent, is-

l. In a grain separator, the combination, with the main sieve and an endlesscarrying apron, of an elevator arranged at the rear or discharge end ofthe sieve and adapted to receive the discharge of the machine and elevate such discharge onto the endless belt and operating mechanism, substantially as set forth.

.2. The combination, in a grain-separator, of the stationary inclined sieve, the endless apron having cross-slats and moving down on the said sieve close thereto, and an elevator arranged at the rear' end of the machine and adapted to receive the mixed grain and tailings and elevate and deliver the same onto the lower end ofthe slatted apron, whereby they are redelivered onto the inclined screen, substantially as set forth.

3. In a grain-separator, substantially as described and shown, the combination of the sieve E, the slatted apron, the hopper, the elevator arranged at the end of the machine and adapted to receive the mixed grain and tailings screened by the lower part of the sieve E, and deliver the same onto the slatted apron, and means whereby the discharge from the hopper may be regulated, substantially as described, and for the purposes specified.

4. In a grain-separator, the combination of the main sieve, the sieve K, the cut-offs P, the cut-oft' M, and the side and end spouts, substantially as set forth.

5. The combination of the main sieve, the sieves K and N, the spouts L and Q, and the cut-offs M and P, substantially as set forth.

6. The combination, with the main seive, of the cut-offs P P, arranged below the lower end of the main sieve and adjustable one upon the other, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
