The Schedule referred.v tuo-1n thus Letten 'Patent and making ypmtof the name.

To all whom it may concern Be it known -t-liat l, .Tous E. Asnnnsx, of Boiling Springs, in theI county of Cumberland, and State Vof Pennsylvania, have invented a new and useful Improvement in Grain-Cleaners; aud'I do hereby declare that the following is a full, clear, and exact description thereof, which will enable'others skilled in the art to 'make and use thesame, reference being4 had to the i accompanying drawing, forming part of this specification,`in which the ligure represents a sectional side.

view of the invention. 4

Similar letters of referencel indicate like parts. The object of this machineis to accomplish the .cleaning'ot' grain in the most'eiiective andperfect manner, and with the fewest and simplest alrangements ofparts.

It consists, in general terms, f a seeming-wheel, revolving with high speed,"which encounters the entering grain and 'agitates it, thereby .thoroughly loosening itfrom `the chess and c'oekll and chaff. The grain is then delivered from this wheel upon an inclined screen, when itA encounters a blast of air from a re-4 volving-,ian-wheel or' blower, located within the geuL eral frameof the machine, and immediately below the i scouring-wheel.`

, The sereeirsnot a plaugsnrface, heretofore used, but is corrugated in the forni of steps, running crosswise to the ldirection'of` the blast Ifrom the fanfwheel,

so' that the kernels of cleaned' grain will catch against the' coriygations, ,andy retained from being blown out with the chan'.l v,

Other devicesfperfecting the operation of .the machine, will be set forth in the following specific descrip tion of the same, which latter is made with reference to the accompanying drawing. l

The general flame of the machine is letteredA A A, 8m., and contains thefamwheel E, 4within the drum D, which latter connects "with, the board P, and also with'thebottom'plank j, thus leaving an opening at the foot' ofthe inclined screen L', the upper surfaceof which latter 'receives the blast of air from the fan wheel through openings in the drum, beforedescribed.

The screen'is affixed to a frame, M i, which latter is pivoted-*at its vupper end 'on a cross-rod, k, on which it vibrates vertically, when actuated to do-so, by the revolution of the projections on thefshait h.. the latter being revolved bya pulley onjits 'e1d,.ex`tei'ior to the frame of thegmachine. Y v

The scouring-wheel iscnclo'sed within aA drum, of 4wood on sheet-iron, or other suitable material, and the grain enters .the said drum through the hopper'l G, opening into thedruln, as shown. `After passing through the wheel, the grain is ,thrown out at J, and descends on the chute-board' Kon to the screen, where it enfconterthe blast at the lower edge of the chute-board EK, whichblows the chatl' through thescrcen into the chal'boxB. j l v The-chess andcockle,so called, also pass through t'he meshes ofthe screen, 'and fall'iuto the bos B, while the cleaned grain'isfshaken down, and falls from' the screen throughvllgbeopening e, in theplnte', and also,l

through the openin f, in the bottom of the frame, 'where it is caught tign underneath the latter opening.

Thedrum containing the scouring-wheel is formed with lapping staves, b b b, &c., as shown, the upper half presenting theedge-s of the staven .to arrest the v cetripetal tendency of the grain as it is thrown 0fl`- v imitate the lapped stares.

The scouring-wheel consists of a hub-boss, H, on a shaft,` o, and provided with flanges, I, which latter contain 11i/dial groups of transverse rods, m, of metal, and cross-vaues, 1t, connecting their peripheries. l

The luibfboss H is also provided with the cross-venes l, 'which conduce t0. the agitation of the graii by throw# ing it fromthe hub' centiifugally among the rods.

:The plate or block N- is for the purpose of directing a portion of the blast through theI openingO into the ehabox B, and is made in a wedge-form, so vthat-the heaviest part of theblast, which act-s against the screen,

v will not get under the bottom plate n when it isat its lowest pointof vibration.

The stop-board 1) is for the purpose of keeping ythe gra-in from being blown into the elsif-box as it encounters that part of the blast through 0.

- The board-P, 'oining the chute K, is for the`purpose of contract-ing the blast, so that it may act with the maximum intensity upon the grain as vit falls from the said chute.

Q is a wall, which is set out fnom the wall of the box. There are' two such boards, one on each side of the screen-flame M, and against which the latter works with easy contact.

l There are'two pulleys on the shaft of the scouiingwheel, and two on the shaft ot' the fau-wheel, and a pulley 'on the shaft h, which agitat s the screen.

One of the pulleys on the-shaft o' bears a `oelt from the powerpulley which drives the machine; the otherA pulleynon the shaft o drives a 4belt rluining on the-fanwheel; and the second pnlleyon the fan-wheel shaft (hives a belt on the pulley of the agitator-shaft h.

Having thus described my invention, ,v

Patent* y 4 l 1. The scouring-wheel, substantially as described,

when forming part of a4 graiufcleaner, all as setforth.

2. .The arrangement `of the scouring-wheel above the fan-wheel, with the chute-board K, inclined screen L, and chad-box B, all substantially as set forth.
