The frame ofthis machine, for containing and supporting the several parts, of the. machine, hereafter described, is made by framing together suitable timbers of the; requisite size and strength for the purpose, intended-one end being elevated above the other for the purpose of" giving-the cylinderthe required elevation.

The inclinedperforated case in which the grain is cleaned is composed of two, parts; A and B. The part A in which the grain is first received and in which it is subjected to the first beating operation is composed of a number of parallel strips of wood P nailed to heads Q, fixed in the frameto which strips, are nailed plates: A of sheet iron, having a number of parallel openings in each. plate punched outwardly for the free srated from the. grain. The platesproject over and beyond the inner ends of the. strips orrrcn.

:escape and" discharge of the dirt as sepa- -of wood about two. inches, saidprojecting 4 portions not being perforated and every alternate plate is made to, extend to the inner isurf'ace of the case B. These projecting 5 ends which are marked it are for the. purpose of directing the wind from the large 'part of the ease into the small part. The object. of making use of the parallel strips of wood P, in the formation of the outside of this case is to form abrupt: ledges for; the. grain to be thrown against by the cen- Ltrifugal action of the revolving wings a order to. break the smut kernels. An open- "ing X for the introduction of the grain to the interior of thegcase is made in the. top. The lower segment of the case is made. in f a similar manner, excepting that it has no sopening in it. like that marked X. There .is', however, an opening'left the upper 1 head of this lower segment, into, which the inclined spout. L. is introduced, through "which a blast is! created by the revolving of the heaters M, N, for carrying off the smut and dirt, from the grain through said l spout. Y The head Q; between the two sections of the cylinder A, B1, is made of inch boards in two, parts, having a round opening in the same the diameter of the smaller portion A, "of the case into which it'is inserted, said head beingfastened to, the end of the larger portion Bfof the cylinder oroase bymeans iof' blocks 6. fastened to. the-outside, of the 508456 Binto. which scr ws; passing th ough the. head Q are inserted- Th a ger por- 11 of the case B, in whichthe scouring ;process is con nued, and in which the blas I is created by. the large wings N is m de.- of .smooth sheet. iron punched on the inside, t-werdly-, n oblongopenings, hroug which the air is. driven, ogether w h the 1 smu that is; secure from. the, grain.

tom.-

meansthe upper segment or half of the cylinder being held down upon the lower half by means of notches in the heads, into whichthe buttons Z turn. In the lower end' of the bottom half of the cylinder is an opening 11., through which'the grain is dis-" charged into the receivera, and thence t'o the vibrating spreader D and thence to the windspout H, said opening n being provided with an oblique guide plate 72. for guiding the grain out of the cylinder'into the receiver a. The receiver a is an oblong chamber formed against the lower end of the cylinder open at the top and bottom and pivoted on the inside with a triangular guard R, and a rectangular guard S, so arranged, as represented inFig. 7, as to pre vent the grain escaping upward through the receiverthe grain striking against the said guards and rebounding to the bottom, while 'the grain which may escape through the" 'central opening of the case passes through the space between the guards to the bot-;

A vibrating or. shaking spreader D is arranged below the lower or open end of the receiver a. This spreader is made of. sheet metal in the form of an inclined spout, having three of its sides turned upward nearly at right angles with the bottom'the lower grainsuspended at one end by straps to the receiver and at the other end to alever, from which it receives its motiona spring E being connected by its lower end to the spreader, and byits upper end. to the receiver for drawlng it back, when moved by the aforesaid lever.

A case J, K, for the fan to revolve infor creating a blast through the wind spout H isconstructed against the outside of the upper part of the frame in two parts; which case is connected with the spout H at I being acontinuation of the spout. The-part K of the case is attached to the frame permanently. The part J is madein the form of a cap and is removable at pleasure. The wind spout extends from the fan case to and beyond the lower or rear end of the frame. The end I that joins to the lower end of the which revolves toward it in the direction of the arrow No. 2 Fig. 5 and which causes the air to have a direction transversely from the chamber I to the'side I opposite in the direction of arrow No. 1 Fig. 5 when it spreads and passes through the spaces between the partitions Z) in the-spout I-I in the direction of the arrows No. 3. These partitions are designed to direct the air throughthe spout H in a broad even column, filling the whole spout, having an equal pressure. The-parframe.

titions are made of a trapezoidal form, ar-

ranged in such a manner, thatthe space between their. inclined edgesi b and the end H of the wind spout will form a. trapezoideor in other words the partition nearest the chamber I will be farthestfrom the end of the windl spout and the other partitions, gradually approaching the end of the wind "SPOlltjilS they recede from the chamber I as is more clearly represented in Fig. 11. The

object in thus arrangingthe said partitions, the one in advance of the adjacent one, as

described above andrepresented in Fig. 11 is for the purpose of procuring a wideand even' current of air lengthwise the spout from'a narrow fan revolving crosswise over iteach partition arresting the proportion of the air that it is designed should pass between it and thenext parallel partition. The bottom of the wind spout extends toward the discharging end of the cylinder horizontally until it is near the opening 0 in the same, through which the cleaned grain is to pass-it then descends at H toward said opening at an angle of'about 35 degrees. It then rises'toward the rear end of the frame at H 'through which it is extended at an angle of about 45 degrees above the'sides of the spout. Over this end of thespout the chess and other light stufl are blown. The top of the wind spoutis made as follows. IteXt-ends horizontally overthe' upper ends of the partitions from the fan case, past the ends of the partitions at H*- it then slopesdownward toward the discharging end at an angle of about 30 'degrees, until the spout is reduced about one third its depth as atH the top is then extended horizontally at H toward the discharging end until it reaches nearly over the slit in the bottom, through which the grain descends-the rest is open on top. Theob ject in thus contracting the depth of the spout is to condense the air and cause it to spread transversely and escape inabroad even sheet.

The shaft T, for carrying the cylinder with its narrow wings, and the wide wings at the end of the cylinder, and the fan,and

driving pulley, is composed of a cylindrical bar of iron of the requisite diameter and length made to turn in suitable boxes in the The fan V, for driving the wind through the wind spout,is made in the usualmanner and attached to the shaft.

- The narrow wings M for beating the grain against the'ledgesin the case A, are

nailed to strips of wood P Fig. Swhic'h are again nailed to the cylinder-said strips-of 'wood'being extended beydnd the lower end of the cylinder into the part of the'case 'B,

to which strip the wide wings N, are also" nailed. Against the upper end of the cylinder is fastened a circular head'ofsuch diamete'r as to extend to the outer edges of the wings .M. Segment plates are inserted between thewicle wings, nailed to the lower end of the cylinder, forming a circular head extending to the outer edges of the wings, to

wings to prevent them from being thrown off by centrifugal force. The object of making the wings that. revolve in the ribbed por tion of the case, smaller than the wings that revolve in the larger and smoother case B, is, to reduce the velocity of'the wings to prevent breaking the grain. The larger wings having a greater velocity, .will not break the grain, as the portion'of the case in which they revolve is smoother than the w portion A. Another effect produced by the use of the large wings, is to force the wind and particles of smut through the openings in the smooth part of the case B, and also into the smaller or ribbed part of thecase A, the wind passing over the aforesaid projecting ends it of the plates, which are made to form wind guidesevery guide or wing 29, or every alternate wing or guide being extended from the edges of the ribs to near the inner circumference, or smooth surface of the larger portion of the case, and thus made to serve the purpose of guides,a portion of the wind and smut being forced through the aforesaid openings in the plates, and a portion of the wind being forced out of the case through the inclined spout, carrying with it the chaff &c. in the plates and cylinders are punched outwardly from the interior of the case in the manner represented in the drawings at Figs. 1, 9, and 10 with a sharp edged thin wedgelike tool, which will indent the metal, forming oblong depressions having a thin perforation in the middle of each, through which the wind, smut, and dust pass. These depressions are thus made for the purpose of forming receptacles for the grain, into which it inclines as it is driven round in the cylinder by the wings producing more friction than in cylinders made with even, regular surfaces, besides rendering the machine more durable and producing better conductors for the dust and dirt and not liable to Wear away so fast around the issues.

I intend in some cases where there is but little hard smut, to make the whole length of the cylinder like that described in part B, Fig. 1(this mode being sufficient to take out the soft smut) omitting the part repre- The apertures sented at A Fig. 1 the machine beingmade cheaper in this way. v V

The airis admitted to the fan case through a trunk or tube leading to the exterior of the building, excluding the air of the room in which the machine is placed from the fanotherwise the air entering the fan would carry in with it dust and smut, a portion of which would be apt to descend with the grain.

The machine being put in motion by the application of any convenient power to the driving pulley, the grainto be cleaned is introduced'to the interior of the case through the aperture Xit is then met, or struck by the wings M, andthrown against the plates A,of the rlbbed part of the cylinder-it again struck by them, and thrown against the plates, and in this manner the beating operation is continued until the grain arrives at the smooth part B, wherein it .is forced round with great velocity until it arrives at the discharge aperture n, through which it passes to the receiver a, and into the spreader D, which has a longitudinal vibratory motion which spreads it in a broad even sheet, as it descends through the wind spout H-when it passes through a blast of 7 wind from the fan V and is cleaned-t-he motion of the spreader D being produced by the, lever G, which is connected to the lower port-ion of a suspended vibrating bar V by means of a connecting wire W, said bar being attached to the head of the cylinder by a pin o, and resting against an eccentric or cam on the shaft which produces, when revolving, the required vibratory motion.

-What I claim as my invention and desire to secure by Letters Patent, is,

1. The peculiar construction of the case A B as described, being made in two sections A B theone of small diameter with ribs P and perforated plates A extended then rebounds toward the wings, and is beyond the ribs, forming wind guides, the

cylinder, as described and represented at Figs. 9 and 10, in combination with the smooth beaters.

8. I also claim the construction of the receiver at, having the triangular and rectangular guards R, S,"and the oblique space between them in combination with the vi-. brating spreader D, arranged and operated in the manner and for the purpose\ described.

4:. I likewise claim Constructing the spout H with parallel vertical partitions 6, set in advance of each other in the manner described for the purpose of distributing the Wind from the narrow fan in a broad sheet in the spout before reaching the grain in its descent from the spreader as before described.
