UNITED STATES PATENT OFFICE J. W. HOWLET AND F. M. WALKER, OF GREENSBORO, NORTH CAROLINA.

SlVIUT-MACHINE.

Specification of Letters Patent No. 4,512, dated' May 9, 1846.

To aZZ whom it may concern Be it known that we, J. HowLET and F. M. VALKER, of Greensboro, in the county of Guilford and State of North Carolina, have invented a new and improved machine for cleaning wheat of all impurities and also of strengthening the hull of the same by the application of steam thereto; and we do hereby declare the following to be a full and exact description of the construction and operation thereof, reference being had to the accompanying drawings, making a part of this specification.

Figure l, is a perspective elevation of our machine. Fig. 2 is a vertical longitudinal section of the same. Fig. 3, is a perspective view of revolving disk and parts attached thereto, detached from the machine. Fig. 4, is aperspective view of the under side of the revolving disk and parts attached thereto. Fig. 5, is a perspective view of the under side of stationary disk, and parts attached to the same. Fig. 6, is a perspective view of steam box.

Ourmachine for cleaning and steaming wheat, is inclosed in a frame of suitable form and strength, (as represented in the accompanying drawings) constructed in the usual manner, of posts and rails.

A is a drum firmly secured in the frame.

D, is a vertical shaft, passing down through the center of the drum.

C, is a revolving disk secured to the shaft D, and inclosed within the drum A,

m is a vertical rim surrounding the revolving disk C, and cast solid with the same.

a, and o, are vertical concentric rings, cast on the face of the revolving disk, and placed at equal distance from each other and the rim m, with which they are concentric. The inner 0r concave surface of the rim m, and the rings n, and 0, are fluted with vertical flutes.

E, E, are hollow arms, opening into, and strongly secured opposite each other, to the rim m. The rings n, and 0, are divided into two equal parts by vertical openings on opposite sides of each other, descending from top to base. The openings in the ring fn., are placed a short distance to the left of the openings in the rim m, leading into the arms E E; and the openings in the ring 0,

are placed a short distance to the left of the openings in the ring a.

B, is a stationary disk let into an opening in the top of the drum A, immediately over the revolving disk C, and passing down within the rim fm, of the same, to the top of the flutes on its inner surface. The stationary disk B, is secured to the top of the drum A, by screws passing through the projecting arms m, w, m.

it, ZL, 7c, 7c, and Z, Z, are rubbers projecting from the lower side of the stationary disk B. The two rubbers Z, Z, pass within the ring o, their outer surfaces are of a convex form, corresponding with the concave fluted surface of the ring o, and are iiuted in the same manner as the ring. The fluted surfaces of the rubbers Z, Z, are placed suiiiciently near the concave in the ring o, to break up all smut, cockle, or lumps of earth that may be in the wheat, and also to thoroughly rub and scour the wheat. The rubbers c, 7c, pass between the rings 0, and n, their rubbing surfaces are also convex and fluted, corresponding with the concave fluted surface of the ring n; the rubbers le, la,

are placed the same distance from the ringn, that the rubbers Z, Z, are from the ring 0. rI'he rubbers 71 h, have convex fluted rubbing surfaces corresponding with the concave fiuted surface of the rim m, and are placed the same distance from the rim, that the rubbers Z, Z, are to the ring 0. The rubbers Z, Z, and Za, 7s, are permanently secured to the disk vB The rubbers it, 71 have their largest ends secured to bolts passing through the disk B, on which they vibrate; at their other ends, there are projecting bolts y, y, passingup through slots' a, in the disk B, and are secured to the spiral springs a, e, on the top of the disk, which gives a flexible bearing to the rubbers against the concave surface of the rim m.

The wheat to be cleaned is placed in hopper Q, constructed in the usual manner, and passes from the same through the opening t, in the stationary disk B, into the center of the revolving disk C, and is first acted upon by the rubbers Z, Z, and ring 0, it then passes out of the openings in the ring 0, and isl acted upon by the rubbers Zo, Ze, and ring a, it then is forced out of the openings in the ring a, by the rubbers 7c, le, and is next rubbed between the rubbers it, h, and the rim m; the rubbers ZL, it, forcing it into the openings in the arms E, E. The wheat is thrown with great force from the arms E, E, against the sides of the drum A. The oblique beaters or rakes F, F, beat the wheat after it falls into the drum A, and also gathers it t0 the central opening u, surrounding the shaft, through which it frills into the fan V, immediately under the same. The blast of the fan forces the Wheat and dust into the inclined spout H, the dirt and dust is forced up and out at the top of' the spout, and the Wheat by its greater specific.

gravity, falls into the steam box G, on to the Wire grating b. very hot steam from a generator or steam boiler, is admitted through the opening c', under the rear end of the grating b', which forces any remaining impurity that may be in the Wheat out through the trap door 9,- on the top of the steam box, andthe Wheat passes out at the front end of the steam box, in a Vfit state for immediate grinding; The eect of the steam upon the hull of the Wheat, is to strengthen and toughen it, and causes the bran to peel from the Wheat in L powerful jet of would be the case, did the Wheat pass directly from the machine'to the `mill stones, Without its being first acted upon by Steam.

VVhtt' We claim as our invention and desire to secure by Letters Patent, is-

The revolving and stationary disks C,-

andB, With the rubbers Z, Z, 7c, la, and h, L, and rings 0, and n, and rim m, combined and operating With each other,landin combinationtherewith,the arms E,`E,` andbeaters F, F, `substantially 'inj the manner and for the purpose herein set forth,H J. W. HOWLET. F. M.,WALKER.
