The Schedule referred to in these Letters Patent and making oi the name.

To. all whom it may concern;

Be it" known that we, Div-James I. SMITH and WILLIAM H.-N1c.o1 mws, of Frederick, in the county of Frederick and State of Maryland, have. invented-a new; and nsefulxImprovement in Grain-- fanning and Scparating-li'lachines, and we do hereby declare that the. following is afull, clear, and exact description thereof.

'lheobject'of our invention is to produce a grain fanning and separating-machine, which will have a greater capacity than those now in use, and-will be, at the sametime', more easilyoperatedand less liable to get out of order. 'lhel'rature-of the same being that the fan is operated by an adjustable eccentric ou the flux-shaft, and to which the shaker-bar is attached, and by which the riddle-carrier or shoes 'is operated,

the shoe being hung on two bars, which are snspended from the inside nearthe top .of the frame of thefmachine, on'pivots, aml are attached in the same manner to the shoe and nearthe bottom, allowing the riddles to have a full backwardand forward motion,

the riddles being held in the shoe .bymeans of grooves in the sides of the same, the arrangement of the lower riddles, being such that they culminate at the center and underneath. t v

the two first. or

ing each with the other, for the purpose of carrying .oti' the chafi and waste, the lining of each riddle being depressed as it approaches the tubes.

At'therear of the machine is a novel attachment,

- consisting of an inner tail-board with chute attached, I the tail-board screen and chute at one end of the screen. This device admits the use of, the greatest amount of blastwhen there is a large proportion of garlicelods, pebbles, and other extraneous matter in the grain. The chute attached to the inner tail-board allows the over-shot grain to fall on the'screen, while the chute at the side of theshoo receives the garlic, &-cjl,-thro'ughthe break 'or opening at the lower part of-the screen, and empties it on the floor. Outside cums attachment is the adjustable tail-board, which -is moved up or down-near the mill or out from, as may be desired, to catch "the headings and tailing. It is support it.

made adjustable by the use of'the slotted arms which To enhance the value and general utility of my .machine,. L have attached .a-most convenient and efiicicnt weighing and bagging attachment, consisting of aigraduated beam and weight, and a sqnarercvoiving bok, furnished on each sideoi tho sqnarcwith a j .p 'ojecting cylinder, each cylinder being arranged with I a swing wire and catch to hold the bag in-itsplacep and as' each bag .isiilled and removed, the weight of the next hag,l ngcu the cylinder above, turns the revolver and brings the cylinder to which it is attached directly under the discharge-chute. The revolver has. also attached on the outside a dial-plate;and hand to register the number of bushels cleaned.

of the weighingapparatus is attached -a cutoff, working automatically over the mouth of the chute, so as to. stop the flow of grain at any desired point, or when so much grain is weighed or measured.

To enable others skilled in the art to make and use my invention, I will proceed todescribe its construe- 'tion and operation, reference being bad to the accom; panying drawing, which is made a part of this spec itication, and in which like letters indicate liks parts.

Construction.

I make the frame A, fig. 2, ot'.my machine, very much in the usual nianner and style, except that the drum B, which iucloses the fan 0, is placedina more. elevated position than usual, and is made adjustable so that it may be removed at pleasure, and, allowing room underneath for the riddle-box D, as shown in The. shoe or riddle-carrieris hung directly underneath the hopper, it being suspended from the sides of the frame by means of the bars i a hung from each side and near the top of the frame, and loosely attached to the shoe near the bottom. l

. The riddle-carrier is kept securely together by means of the transverse bars 11 b, which act as braces, and is grooved on the inside of its uprights in a peculiar manner, so as to admit of the novel arrangement of the riddles, which are placed in the shoe in the fol lowing manner: I v

The 'upper or straight wire riddle E is fixed in a groove in. the ordinary manner, that'- is, in nearly a horizontal, position and inclining slightly toward the rear of the machine, and is made of a number of metal rods set in the back-oi the riddle-frame several inches apart, and extended longitudinally, while the coaise Onthe beam square-mesh riddle F is placed just below it, but in a perfectly horizontal position. Next to the riddle F, and below it, is placed the lopg double riddle G, which is inclined about an angle of 30, and extends with its lower end almost under the. fan 0. This riddle is made witha bottom or lining, which is broken or slotted about the middle zz, while the riddle itself has four or more openings, 9: a: x :c, directly over the break in the lining, more clearly shown at fig. 6, so that only about one-half the'graiu traverses each portion of the riddle, the upper portion "of wh ch is squaremesh, and the lover portion is the long mesh, thus providing for a more thorough dispersion and screening of the grain. Directly under the middle and under the break 2 in the lining of the long riddle G, the longmesh riddle H is situated, extending downward and at ah equal angle with the long riddle, but in an opposite direction, and toward the rear of the machine.

Commencing at the bottom of the riddle H, and extending downward at about the same angle, and in a contrary direction, is another square-mesh riddle, I, terminating at the chuteO, directly below the center ofthe long riddle G.

Underneath the lower end of thclong riddle, and extending a little beyond it, and almost under the fan, is the last riddle K, which extends downward, at about the same angle with the other riddles, to the chute 0, the three riddles H, I, and K. together with the lower half of the long riddle G, being arranged so as to conform to the shape of a lozenge or rhomb. Near the lower end of the bottom riddles, I and K, there is an opening or slot, 0 c, in the lining of each, at either .side of the chute O, to allow the chad and waste to escape to the screen-box, which is placed underithe bottom of the machine and below the chute. g

The riddles G, H, I, and K, are connected by double adjustable tubes aha, and u, as shown infig. 1, that is, the tube it connects the, lining of the upper part of the long riddle G with the lining of the riddle H. The tube a connects the lining of the riddle H with that of the -riddle I, and'the tube 'zflconnccts the lining of the lower part of the long riddle Qwith the.

bottom of the riddle K, securing, b this arrangement, a free avenue'ot escape for all the chaii' and screening, so that the same may empty into the screen-box, through opening 0 c in the lining'oi' the riddles I and K, the lining of all the riddles being depressed as it approaches the tubes.

The advanta es of makim the tubes double so as g a a to be adjustable, is obvious, as, whenit is desired to change or take out one of the riddles, the lower part of the tube is pressed up and out of the way, while the riddle is being withdrawn.

At the back of the shoe, and attachedto it by hooks a, is the inner tail-boardM, furnished with the chute in, which, when a great amount of blast is used, catches the overshot grain and other substances, and causes. the same to fall into the chute m, by which it is conveyed to the tail-board screen L, which separates thegrain from the garlic and other foreign substances.

This screen is made in a peculiar manner, and is shown at L d s. 7 7" and is somcthin in the sha e of an a g 7 g obldng box, open at the inner side, and having a perforated lid, the lid at the lower end extending of the edge of the box, and slotted, so as to allow the garlic and other foreign matter to fall into the chute l, which is attached to the shoe, which is inclined to the rear of the'machine, and discharges'the waste onv the floor, while the grain passes through the perforations. in the lid and'in the box, and escapes from thence to the box underneath, which is provided for the over-shot grain. or into the screen-box.

v The tanOis made much 1n the usual way, except that the wings or'fliers are separated at the middle, s'o as to admit of the play of the adjustable eccentric R.

The fan -is operated by acogged driving-wheel, d, working ona pinion, e, on the cadet the fan-shall;.- The eccentric R is madein the manner shown at figs;

5 and 5", slotted so as to be adjusted on the fan-shaft. Oneach side of the slot in the eccentric the flanges r r are extended, which are also slotted, to admit the screws v v which enter the fan-shaft, and hold the eccentric B securely in place, after the same has been adjusted, so as to give the desired stroke to the shakerbar 8, which operates the shoe, and is attached tothe transverse-bar k which extends across the shoe.

The weighing and bagging attachment is situated on the outside of the machine, near the bottom, and immediately in front of the chute O, and consists of a graduated beam, y, and weight, '1 ,the tenon of the beam ybeing let in the m'ortise on the shaft of thebagger, which extends through the bagger, and has a small pinion attached to its extremity. The bagging device W consists of a square revolving box, having an open cylinder, X, on each of the-four sides, to which the bag is attached by means of the spring wire and catch 10.

The indicator Z,-which is placed on the outside of the bagger, is composed of a dial-plate and hand or indicator, the dial being graduated and marked with as many radiated lines as there are cogs in the wheel which moves the hand, and which is operated by working on the fixed pinion on the shaft of the bagger, so that, every time the bagger turns, the hand indicates it by moving forward one space. On the shaft of the bagger the cut-ofl' t is placed, and works in front of the chute 0, so that, the scale being set any certain number of pounds, the grain falling in the bag overbalances the weight on the beam and beats the shaft down, thus bringing the cut-elf t over the moutlrol' the chute 0, and stopping the flow of the grain.

Operation. The machine being set in motion by turning the driving-wheel d, which imparts motion to the fan 0 by means of the pinion e and the eccentric R on the shait, and from thence the motion is transmitted to the riddles by the shaker-bar g, attached tothe shoe.

The thrashed grain. chad, heads, &c., being thrown in the hopper, fall from it to the straight-wire riddle E, and are sgparated, so as to fall in strezuns on the coarse squareanesh riddle F, thev grain-and fine screenings falling through, while the straw and coarse stnii'is blown out.' The grain and line screenings fall on the long double riddle G, the grain traversing the length of the riddle, and a portion going through the break 2' in the center, and falling on the long-mesh riddle H, spreading over this, and dropping over the lower edge on the lower riddle I, from which itis discharged into the chute O, and carried to the bagging appaiatusW,

The grain which falls on the lower part of the long riddle G traverses it, and falls over its lower end, and on the bottom riddle K, which also discharges in the chute 0, leading to the bagging and weighing apparat'us.

The screenings arev blown through the riddles-and I upon their lining, and find their way through the tubes at, a, and a, to the breaks or slots 0 c, in the lining of the bottom riddle. on either side of the chute O, and escape to thewaste or screen-box underneath, the course of the grain and screening being indicated in the drawing by arrows.

\Vhen a full blast is used, a quantity of the grain, together with the garlic, pebbles, .&c., is often blown over the upper end of the long riddle G, and is thrown against the inner tail-board M,-and falls into the chute m, on the'tail-board, and is discharged from thence to theuppr end'of the head-board screen L,"thegrai;si

dropping through theperforations,- and m a box pro-1 .vided -for'the purpose underneath, whilethc'garlic,

pebblcs,'&c., pass out through the slot L, shown in inthe lower endof the sceen, into the chute I, on'the inside, eshoe, and fall upou t-he floor;
