WHEAT-CLEANER.

SPECIFICATION forming part of Letters Patent No. 309,684, dated December 23, 188%.

(No model.)

To all whom it may concern.-

Be it known that I, SOLOMON BERNHEISEL,

a citizen of the United States, residing at Green Park, in the county of Perry and State of Pennsylvania, have invented certain new and useful Improvements in lVheatOleaners, of which the following is a description.

This invention relates to that class of dc vices used for scouring and polishing grain; and it has for its object to thoroughly clean the grain from its outer skin and from smut or other substance that may be stuck thereon, and to clean out the groove in each kernel of grain.

To this end myinvention consists in the construetion and combination of parts hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation partly broken away to show the interior. Fig. 2 is an end elevation partly broken away to show the interior. Fig. 3 is a longitudinal section of the cylinder and drum, and Fig. 4 is a transverse vertical section of the cylinder and drum on line :20 a" of Fig. 3.

A represents the body or frame of the machine. B is a close chamber constructed in the usual manner, in which the securing device operates.

This device consists of an external drum, 0, made in halves, divided on a longitudinal plane, and mounted to revolve in the frame on hollow trunnions c, and a cylinder, D, also journaled in the frame to revolve in the drum. Each half of the drum comprises three staves, E, filled with brushes 6, a stave, F, of wirecloth, and a semi-cylindrical shell, G. Each of the staves E is attached to the drunrheads by means of two binding-screws, a, which hug it toward the heads, and a set-screw, b, which pushes it away from the heads. By this means each stave of brushes may be canted a little to one side or the other, or it may be set as a chord to the circle of the drum, and when the brushes become worn they may be set up again to the work by unscrewing the screws b and screwing in the screws to. The stave of wirecloth is to discharge into chamber B the dust which is scoured from the grain. The shell G is to keep the grain in among the scouring blades j of the disks J. The cylinder D comprises a series of staves, H, armed with brushes h, alternating with a series of staves, I, armed with convcyer-wings i, and a series of disks, J, armed with diagonal blades j. H are supported between horns K of the cylinder-heads, and they are adj ustaloly mounted by means of screws a and b, similarly to the staves E, for the same purpose. The brushes h are set to nearly touch the brushes 0, and they act together to polish the grain. The conveyor-wings i are all set in one direction, diagonal to the line of the staves, and they act by slow impulses, like abroken threaded screw, to work the grain from the end of the machine beneath the inlet L, or from the shell G to the Outlet Z. The bladesj of each disk J stand diagonally in one direction; but the blades of alternate disks slant in opposite directions, to beat and rub the grain right and left to thor- Oughly scour it. The drum 0 is provided with an internally-toothed wheel, 0, to be engaged by an intermediate gear-wheel, M, which is mounted on a shaft having a pulley, m, driven by a belt, N, from a pulley, a, on the cylindershaft d, by which means the drumis revolved in the same direction as the cylinder, but at a much slower speed. About one to six is the ratio at present used. The disks J are mounted on the shaft (1, and heldin place by a screwnut, d, which allows the disks to be set as desired circumfcrentially. The grain enters the machine through any sort of ahopper or pipe, L, and is first acted on by the blades j. Then as more grain entering forces along that already in, it comes in between the two sets of brushes hand 6, where it is further scoured The staves and polished as it is worked along by the conveyer-wings t, and is finally discharged at outlet Z, through the lower end of a pipe, 0, which is connected at its upper end with an exhaustblower, P, to withdraw what little dust there may remain not already discharged through the wire-cloth staves F. The cylinder and shell, both revolving in the same direction, one faster than the other, have a tendency to act on both sides of each kernel of grain at the same time, and the drum being armed with yielding brushes effects a more thorough scouring than any rigid fixtures on the drum can do. Even the creases in the grain are cleaned out in practical work.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a cylinder mounted on a shaft journaled in a frame, and provided with externally-projecting scouringteeth and polishing-brushes, of a drum surrounding the cylinder, provided with internally-projecting polishing-brushes, the drum being provided with hollow trunnions journaled in the frame, and the shaft of the cylinder passing freely through the said trunnions and j ournaled in the frame independent of the trunnion-journals, as shown and described.

2. The combination, with a series of disks I mounted on a shaft, of a surrounding cylindrical shell journaled concentric with the said shaft, and means for revolving said disks and r 5 shell in the same direction at different rates of speed, each disk being provided with diagonal blades, and the blades of alternate disks slant ed in opposite directions, as shown and described.

The above specification of my invention signed by me in the presence of two subscribing witnesses.

SOLOMON BERNHEISEL.
