GRAIN SEPARTOA R AND CLEANER.

SPECIFICATION`forming part of Letters Patent No. 287,154, dated October 23, 1883.

Application tiled August 6, 1883.

To all whom it may concern:

Be it known that I, HEBER PARISH, of Burlington, in the county of Des Moines and State of Iowa, have invented a new and useful Improvement in Grain Separators 'and Cleaners, of which the following is a full, clear, and eX- act description.

Reference is to be had to the accompanying drawings, forming a part of this specification, .in which similar letters of reference indicate corresponding parts in all the gures.

Figure l, Sheet 1, is a sectional side elevation of a machine containing my improvement.` Fig. 2, Sheet 1, is a sectional end elevation of the same, taken through the broken line fc Fig. l.y Fig. 3, Sheet 2, is a side elevation of the same. Fig. 4, Sheet 2, is a sectional plan view of the same, parts being broken away.

The object of the invention is to provide means whereby the two-part sieve and screen, (of a separator and cleaner, which balance each other, may be simultaneously shaken, and whereby the sieve may be supported and adjusted, as'hereinafter described and claimed.

A represents the frame of the machine,which is `designed to ybe mounted upon wheels B in the ordinary manner. The machine is inclosed at the sides and top by a casing, C, attached to the frame A. v

In the forward upward part of the machine is placed the thrashing-concave D, above which indicated in dotted lines in Figs. l and 4.. The journals of the cylinder E revolve in bearings attached to the frame A, and to one of the said journals is attached apulley to receive the drivi ing-belt, which pulley and belt are not shown in the drawings, as there is nothing new in their construction. To the other journal of the thrashing-cylinder E are attached two pulleys, F G, around which pass two belts, H I. The belt His crossed and passes` around a pul` ley, J, attached to the end of the shaft K, which is journaled in bearings attached to the frame A.

Upon the shaft K are formed two sets of cranks, projecting in opposite directions and alternatingwith each other, and upon which are pivoted the forward parts of two sets of separating-bars, L. The rear parts of the separating-bars L are pivoted to corresponding (No model.)

cranks formed upon the shaft M, the journals carrying the straw toward the rear end of the machine. rIhe bars Lhave ratchet-teeth formed upon'their upper sides, to cause them to take a better hold upon the straw, and have openings formed through them, to facilitate the escape of the. grain as' it is separated from the straw. f

The belt I is crossed, and passes around a pulley, N, attached to the end of the shaft O of the fan-blower P, by which a blast of air is forced against the grain as it falls from the endless apron and passes down the sieve, hereinafter described. To the otherend 4of the fanfshaft O is attached a pulley, Q, around which passes a belt, R. rlhe belt R also passes around a pulley, S, attached to the journal of the roller T, pivoted in bearings attached to the frame A, and around which passes the endless apron U. The endless apronU also passes around a roller, V, pivoted to the frame A, beneath the concave D, and is made of such a length that the grain received from the separating-bars L will be discharged from its rear end upon the lowerpartof the sieve, hereinafter described.

To the casing C, beneath the endless apron U, is attached a close bottom, W, to receive any grain that may fall from the edges of the said endless apron. The sieve X is made in Vtwo parts or halves, which are placed side by side and rest and slide'upon cross-bars Y, attached at their ends to the lower parts of upright bars Z, sliding in vertical grooves in the side casings, C. The parts of the sieve's X are kept in place at their outer edges by lugs a, Fig. 2, attached to the upright bars Z, and at their inner edges by T-lugs b,.attached to the centers vof the Across-bars Y, as shown inFig. 2.

To the upright bars Z are pivoted the lower lends of the connecting-bars c, the upper ends IOO of which are pivoted to the ends of crankarms d, attached to the rods e. The rods e eX- tend across the machine, and rock in bearings in the upper parts of the side casings, C.

To one or both ends of the rock-rods c are attached crank arms f, which move along curved catch-bars g, attached to the casing C, so as to hold the said crank, and with it the upright bars Z and sieve X, securely in any position into which they may be adjusted, so that any desired inclination can be given to the said sieve X.

Beneath the sieve X is placed the screen-h, which is also made in two parts or halves, and of such a fineness of mesh as to prevent the kernels of grain from passing through it, whilev allowing small seeds to pass through freely. The sieve X and screen h are made of such a length that the grain that drops from their lower ends will fall into the forward trough, fi. To the lower side of the frame of the screen h is attached a screen-board, j, which is made of such alength that the small seeds that drop from its lower end will fall into the trough k, placed at the rear side of the trough i. The tailings that fall from the rear end of the sieve X and from the rear ends of the separatingbars L are received in a trough, Z, placed at the rear end ofthe machine, and which is designed to discharge the said tailings into the well of an elevator, to be carried up by the said elevator and discharged into the thrasher, to again pass through the machine. The grain and the small seeds are discharged from the troughs i la into separate receivers, from which they can be removed when desired.

The contents of the troughs z' 7c l are discharged from the said troughs by spiral screws m a o, pivoted to bearings attached to the said troughsor to the frame of the machine.

To the journals of the feed-screws ma o are attached pulleys 19 q @which are driven by the belt s. The belt s passes around a pulley, t,

attached to the shaft O ofthe fan-blower l?, over the pulley p, under the pulley q, around the pulley u, under the pulley r, and over the pul- `w is designed to give motion to the carrier of 5o a straw-stacker, and may also be used to give motion to the carrier of the tailings-elevator. The pulley v is attached to a journal of a shaft,

,which revolves in bearings attached to the` frame A, and upon which are formed two double cranks.

To opposite parts of the cranks of the shaft :c are pivotedthe rear ends of two connectingrods, y,the forward ends of which are pivoted or attached to the center of the forward ends of the frames of the parts or halves of the sieve X.- To the other opposite parts of the said cranks are pivoted the rear ends of the connecting-rods z, the forward ends of which are pivoted to the centers of the forward ends of the parts or halves of the screen h., so that the parts of the sieve X and screen h will be vibrated by the revolutionl of the cranklshaft m and will'balance cach other, so as to work with very little jar.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a two-part sieve, X, and a two-part screen, h, of the doublecranlred shaftw, the two rods y y, and the two rods z, whereby the shaft :v will simultaneously shake the two part sieve and screen,which balance each other, as described.

2. ln a grain separator and cleaner,the combination, with the casing C and the sieve X, of the cross-bars Y, the upright sliding bars Z, the connecting-bars c, and the rock-rods e, having arms (l and f, and catch-bars g, substantially as herein shown and described,whereby the said sieve can be readily adjusted and will be firmly supported, as set forth.
