SPECIFICATION forming part of Letters Patent No. 479,241, dated July 19, 1892.

Application filed December l2, 1891. Serial No. 414,814. (No model.)

.T0 @ZZ whom it may concern:

Be it known that I, HENRY BUSH, a citizen of the United States, residing at Holgate, in the county of Henry and State of Ohio, have invented a new and useful Fanning-Mill, of which the following is a specification.v

This invention relates to farming-mills or grain-separators; and it has for its object to provide a machine of this class, also known as grain-winnowers, which shall be so constructed as to eectively separate the various kinds of seeds, as well as to remove the chaff, straw, and other foreign matter to be separated from the grain, and, while accurately separating, at the same time discharging each of the separations through separate passages or into separate receptacles.

With these and many other objects in View, which will readily appear as the nature of the invention is fully understood, the same consists in the construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure lis a side elevation of a tanning-mill constructed in accordance with this invention. Fig. 2 is a verticaly longitudinal sectional view of the same. Fig. 3 is a vertical transverse sectional View on the line 3 3 of Fig. 2. Fig. 4 is a detail in perspective of the connected screencarrying bars or frame-pieces. Fig. 5 is a similar View of the rectangular operatingshaft.

Referring to the accompanying drawings, A A represent the side frame-pieces of the machine, forming the air-trunk therebetween and main casing. At one end thereof and also between the same is located the fan-casing B, provided with an inner discharge-opening b, communicating with the space between said side pieces, so that a blast of air from the rotary fan C, mounted in said fan-casing, may be continuously blown or directed forward of the fan-casing and through said air-trunk. The fan C is mounted upon a shaft c, journaled in the bearings c', located at the end of one of said side pieces, and in the bearing-carrying frame D, located to one side of the machine at the end of the opposite side piece, and mounted within said frameD is themain drive-wheel E, carried by the shaft e, journaled in bearings on said frame and operated by the crank F, secured upon the end of said shaft. A belt f passes over said drive-wheel and said fan-shaft, and thus communicates motion to the fan, while to the inner side of the drive-wheel E is secured a belt-pulley G, over which passes the crossed belt g, communicating motion to the feeding and separating mechanism, as will be presently described.

Directly over the fan-casing B is located the double-hopper frame H, which is detachably secured to the top of the side framepieces by means of the slotted angle-bracket h, secured to the side of said frame and held to the top of one of said side pieces by means of the clamping-bolt h', passing through said bracket and through said side pieces.

The frame H is provided with the double hoppers I, having the ordinary inclined bottoms meeting centrally of the frame and having working thereover the hinged lid t', hinged in the opposite sides of said frame, centrally between said hoppers, so that the same may be thrown over either of the hoppers, according as tlie grain is desired to be directed directly into the air-trunk or to rst be directed upon the separating-screens. The lower outer ends of the hoppers are provided with the blocks fi', having the inner vertical grooves @"2 and the slanting grooves i3, the said vertical grooves being designed to receive the regulating or cut-off slides J, working therein, and being designed to entirely close the hoppers or to be raised and to allow the grain to be fed over the edges of the respective bottoms by means of the corrugated feeding-rollers j, journaled in said grooved blocks and working under the cap or guard boards j', fitting within the slanting grooves in the inner faces of said blocks, and thus causing the grain to beheld to the rollers, so that the same will pass thereunder. The feeding rollers are mounted upon shafts extending without the hopper-frame and carrying the belt-pulleys jz, which are engaged by the crossed belt g from the pulley G, according as the grain is to be fed from either of said hoppers, it not being necessary to cross said belt when the innermost hopper is used to direct the grain directly into the air-trunk. The opposite shaft, carrying'the opposite feed-roller, is provided with a supplemental belt-pulleyj, over which the belt ,74 passes and communicates motion IOO to the rectangular shaker-shaft K, mounted in bearings k upon the lower outer edges of the opposite sides of the hopper-frame H, and which carries upon one end thereof the beltpulley 7c', over which the operating-belt ,7'4 passes to communicate motion thereto, as will be readily apparent.

Within the frame H and secured to opposite sides thereof, directly beneath the hoppers l, are pivoted the vertical oscillating screen-levers L,'extendin g above and below their pivots and carrying the screen-frame bars M, the upper opposite pair of which is pivoted to the upper ends of said levers, while the lower opposite pair of bars is pivoted upon the lower ends of the levers, so it can be readily seen that as-said levers are oscillated the said frame-bars `are alternately reci procated back'- ward? and forward. rllhe opposite levers L, adjacent to the rear end of the frame H, are extended below the/lower frame-bars, as atl, and are adapted? to be intermittently struck bythe strike-plates Z', secured upon opposite sides of the rectangulardiamond-shaped or squaredshaftILat each end thereof,-so that thersatne as said shaft revolves travelclose to the inner faces-of the sidepieces of said frame and will-intermittently strikethe lower endsof said levers, so` as tol throw thesame forward an`dbackward,the oscilla-tionslof said leversbeingcompletedlby meansofsaidstrike plates alternately striking the downiwardlycurved actuating-plates Z2, secured tothe under inner ends of the lowerframe-bars M, and are curved below the same in the path of travel of said shaft', sothat immediately after the strikeplat'es upon one side of the shaft havestru'c'k the lower extended ends of said leversthe opposite strike-plates strikesaid curved plates,and thus throw the frame-bars in the opposite direction, thus cansingrapid reciprocations ofl the same.

The frame=bars M are eachy provided with theI inner longitudinal grooves m, that are adaptedto receivethe shaking-screens m', of the' ordinary construction-andsecured within said frame-pieces by means of the lockinghooks or other suitable fastening devicesm?, as illustrated in the dra-wings. Asis usual in devices of this character, the lower screen plateor riddle, receiving the matterfrom the upperiscreen, is also providedwith aforwar'dly-extending imperforate end m3, projecting beyond the inner end1 of t-he upper screenlaud adaptedlto carry theseed which will not pass through the perforations therein over into the air-trunk, which will complete the separat'ions-` thereof, as will bedescribedl Sep arations from the lower screeny pass upon a conveying-pan N, located directly there beneath and carried by the lower pair of frame-bars, and said pan extends-beneath saidt screen t-he length of the perforations therein. The stra-w or stubs or other foreign matter mixed with the grain which is fed upon the rear end` of the upper screen from the rear hopper will not pass through the perforations in said screen, but by the reciprocations thereof is discharged overthe end thereof into the vibrating spout O, directly beneath said end and mounted within said hopperframe. The inner end of said spout O,which is transversely mounted in the hopper-frame,

` is provided with the sliding supporting-pins o, working through the side of the hopperspout, while the other end of the same projects through an opening o in the opposite A engaged by and works between the angleplates P, secured to theinneriuost endof the upper screen-frame bar adjacent thereto and which are extended beyond said frame-bar, to which they are secured parallel with each other and at an angle to the frame, so that as the sameis reciprocatedthe said plates-will carry the stud o3 between the same, and thus cause the said spout to vibrate, and the vibrations thereof will carry the matter without the hopper-frame and discharge the saine into the refuse-spout Q, secured' at an angle to one of the sideframe-pieces A and directly under the outer end of said vibrating spout.

A supplemental vibrating spout Rf islocated directly beneath the inner end of the'conveying-pan N, which receives the smallf refuse seed from the stream directed thereover. The spout R is also provided with thesliding supporting-pins lr atone'end thereof, but which work within one of the side pieces A', while the opposite endof said spout projects th rough the opposite side of the casing and' is supported upon the swinging links fr', whilel the same isfurther provided with' an operating-` studr2, also engagediby apair'of angle-plates P, securedto the inner endof thelower screen*- fraine bar adjacent thereto and`disposed at an angle opposite tolthat of the similarplates secured to the'upper screen-frame bar, so that asthe said bars are reciprocated alternately with relation to each other the saidspouts vibrate simultaneously to evenly discharge their refuse.- outer end directly over the upper end ofthe vertical conducting spoutr S, secured" uponf the outside of the machine and opening be# jected to` the action of the blast of air directed through the air-trunk from the opening b in the fan-casing; The mainY body of the heav- 1 iest and best seed falls directly uponthe in clined chute T, secured betweenV said sidel pieces and passing beneath the fan-casing land tothe rear of the machine, where the The lower spout R has its IOO IOS

seed may be collected in a suitable receptacle. According to the nature and weight of the grain not falling upon the main chute T the same is driven or blown forward under the blast of air from the fan against the dividing and deflecting wings U, soldisposed as to receive the grain thereagainst and cause the same to drop through and into the vertical receptacles u, located at the forward upper end of the chute T and communicating with the receiving boxes or drawers u', directly therebeneath and adapted to slide under the machine in the cleats s and u2, respectively, as will be quite apparent. The said dividingwings are hinged directly above the partitions between the vertical receptacles and gradually increase in height from the innermost wing adjacent to the fan-discharge to the outermost, in order that the grain blown over the top of one wing will be caught by the next succeeding wing and directed into its corresponding receptacle, while it may also be readily seen that the various wings may be moved against each other, as illustrated in dotted lines, so that the grain may be directed into one or more of the vertical lreceptacles and the main chute, thus provid- -b in the inner side of the fan-casing and is adapted to be opened any width desired by means of the operating-lever IV, pivoted upon the inner side of one of the frame-pieces A, and is used to either open said gate or regulatingboard or to allow the same to partially close by dropping of its own weight, according to the strength of blast desired.

As previously stated, when it is desired, the belt g may be shifted from the rear feeding-roller to the front if it is desired to merely separate the grain by subjecting the same to the direct action of the blast of air and the dividing-wings.

The construction and operation of the herein-described winnowerorfanning-millare now thought to be apparent without further description.

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