SMUT-MACHINE.

Specification of Letters Patent No. 3399, dated March 20, 1844.

T 0 all whom it mag/ concern:

Be it known that I, JAMES M- TLARKE, of Strashurg, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Machine for, Cleaning Grain from Smut, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, whichforms a part of my specification, in which Figure l, is an elevation of "my machine and Fig. 2, thehorizontal section through the cylinder.' Fig. 3, is a vertical section through the spouts, concave, cylinder and fan.

The nature of my invention consists in the combination of spouts and fan for blowing the dirt from the grain and an additional fan inside the cylinder the blast from which acts on the grain through apertures in the cylinder which are shielded by the heaters attached to the outside of saidcylinder between which and the concave the a grain is scoured.

This construction of the machine is as follows: In a suitable frame (a) is placed a cylinder concave (1)) having its surface pierced with rows of oblong horizontal slots with. ribs (7)) projecting inward between the rows of. slots; at its lower end there is a bottom, convex on itsinner side, and having a large aperture at the center.

Several inches below the concave above described there is a horizontal fan, the case of which is marked (0). common construction with radial fans on the same shaft as the cylinder hereafter described; fro-m theperiphery of the fan case on one side a spout ((Z) leads up to the top of the concave where it turns into astraight vertical spout (d') that conducts the grain into the concave at the top near the periphery; the grain is led into the spout ((Z) by an inclined spout or shoe (e) from the hopper (f) through a hole in one side about half its height. On the opposite side of the fan case isanother vertical spout which extends up nearly to the topof the concave; this spout. receives the grain from the hottomof the concave and discharges it below the fan case as shown in Fig. 3.

This fanis of inder differing from mine but through the center of the concave and fan case where the fan is der(z') is nearly the length of the concave and is hollow; it is connected with the shaft by arms;extending out from it; on the outside are vertical beaters (2") which are placed at an angle between atangent and radial line; under each ofthese is an aperturerunning the whole length, covered or shielded by the inclination of the heaters, as shown in the section Fig. 2; from the edge of these apertures vanes (i project inward radially, by which, when the cylinder revolves, a blast of wind is forced through apertures (i and falling grain, blowing out the cheat, smut, and fine dirt, through the concave. The cylinder can be reversed on the shaft, when the machine is to berunin a direction contrary to that it was first fitted for no other alterationis necessary of the parts of the machine' The faces of inder is driven by a band from the motive .power passingaround a pulley (is) onthe shaft the grain is fed into a spout [(0) from a hopper (f) abovethe machinegfrom thence it is conducted downthrough a ver tical spout ((2') into the concave, infalling through said vertical spout it meetsa current of air from the fan below which blows out the smut balls, light dirt, &c., before scouring; :on entering the "concave the grain is scoured by the revolvingcylin'der the vanes on the inside thereof creating an outward blast through the falling grain which as soon as the (llrtiS removed from the grain, blows it out through theconcave; the

grain on reaching the bottom isswept out 1 through an aperture-onone side lnto a vert1- cal spout (y) where it is again submitted to the action of1 a blast from the fan, after which it leaves the machine.

I do not claim in the above described machine makingan outward blast by inter nal fans as that has been done but in a cyllVhat I claim as my invention, and desire to secure by Letters Patent is,

1. Constructing the cylinder in the man ner described with vanes on 1ts lIlSlClQ. create a ing ablast outward through apertures made I in the manner and for the purpose herein therein as above described and shlelding set forth and constructed and arranged subsaid apertures by inclined beaters as before stantially as described.

specified and reversing the same on the JAMES M. CLARKE. shaft. Witnesses 2. I also claim the combination of the LAFAYETTE CALDWELL,

Vertical spouts (d, cl, g) with the fan (0) J. J. GREENOUGH.
