JOHN D. BEDVVELL, OF UHRICKSVILLE, OHIO.

SMUT-MACHINE.

Specification of Letters Patent No. 11,823, dated October 24, 1854.

To all whom it may concern Be it known that I, JOHN D. BEDWELL, of Uhricksville, in the county of Tuscarawas and State of Ohio, have invented a new and Improved Smut and Separating Machine; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, ref erence being bad to the annexed drawings making a part of this specification, in which Figure 1, is a side elevation of my im proved machine. Fig. 2, is a vertical section of ditto, the plane of section being through the center. Fig. 3, is a horizontal section of the stationary and revolving smut cylinders.

Similar letters of reference indicate corresponding parts in the several figures.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, Figs. 1 and 2, is a frame which supports the several parts of the machine.

B, is a fan box, placed directly under a platform (a), of the frame, and O, is a curved trunk, one end of which commences near the bottom of one side of the fan box, and passes upward and forms a curve and descends at the bottom of the fan box opposite to the side first mentioned.

I), Fig. 2, is the fan placed within the fan box, B, and hung upon a vertical shaft E, as shown in Fig. 2. On the lower part of the shaft, E, there is a pulley, F.

The shaft, E, extends upward through an air tight box, G, which is placed on the upper part of the platform ((6), directly above the fan box, B, see Figs. 1 and 2. The box, G, communicates with the trunk, O, by means of a horizontal passage, H, as shown in Fig. 2. The passage H, also communicates with the fan box, B, as shown in the same figure.

On the shaft, E, and within the box, G, there is placed a cylinder, I, which cylinder is formed of a series of flat metal bars (19), secured vertically to top and bottom heads (0), (a), see Figs. 1 and 2. These bars are so attached to the heads, (0), (c), as to overlap each other, and the outer edges of the bars, in an operating machine may be about half an inch distant from each other, the spaces between the bars being sufficiently small to prevent grain from passing through,

but at the same time, admitting a current of half an inch, and from this space a spout,

K, leads into the trunk, C, as shown in Fig. 2. L, is a valve at the upper part of the trunk, O, shown in Figs. 1 and 2.

At the upper part of the box, G, there is an opening, (03), see Fig. 2, through which p the grain is admitted into the space between .the two cylinders, I, J.

Operation: Motion is given the fan, D, and the cylinder, I, by means of a belt passing around the pulley, F, and the grain to be cleansed is poured into the space between the two cylinders, I, J, through the opening, (d), as the cylinder, I, rotates, the smut is scoured from the grain and pulverized or broken by means of the edges of the bars, (6), which give a corrugated surface to the cylinders.

The fan, D, causes a current of air to pass through'the trunk, as indicated by the arrows, 2, see Fig. 2, and the grain, indicated by arrows, 1, passes from the cylinders down the spout, K, into the trunk, C, where it is subjected to the blast which carries upward in the trunk, the smut, dirt, chess, etc., indicated by arrows, 3, and the grain separated from impurities, falls from the trunk.

Certain portions of the smut and dirt also passes through the cylinder, I, and is drawn down into the fan box, B, by the action of the fan,-and forced out at a passage, represented by (e), at the side of the fan box.

The portions of smut, dirt, chess, etc., that followed the grain into the trunk is carried over the curve at the upper part of the trunk, and the smut, dirt, and light particles are drawn into the fan box, B, at the connection of the passage, H, with the trunk, while heavier substances of some value, such as chess, light grain, etc., see arrows, 2, will resist the power of the current, and fall from the spout, at the end opposite to that from which the perfect grain passed.

By regulating the valve, L, at the upper part of the trunk, C, the blast or current within said trunk may be increased or diminished, as desired.

By the above invention the grain is thoroughly cleansed from all impurities, and the sound grain, smut, and dirt, and chess, and

imperfect or light grain, are separated from each other.

By this arrangement, the smut is more rapidly and thoroughly expelled or drawn off and separated from the grain, while scouring, through the meshes or spaces of the two bar cylinders, thereby avoiding discoloration of the wheat by loose smut adhering to the blossom ends of it and whereby the Wheat is more perfectly separated and cleansed from smut, dirt and other impurities,

I do not claim as new the combination of a stationary outer and rotating inner cylinder constructed of metal bars with spaces between them and the bars in the outer cylinder overlapping each other for the passage of smut, dirt etc. within or through them: nor yet do I claim a close outer case or cylinder surrounding the beaters and communicating by a suction or draft passage with a fan or blast separating trunk, arranged as described, as such is common to other smut and separating machines; but

What I do claim as new and useful in smut and separating machines and desire to secure by Letters Patent, is

The rotating inner and stationary outer cylinders (I and J), both constructed of overlapping metal bars substantially as specified, when combined and arranged with an outer close cylinder (G) and operating in connection with a fan blast or suction made to communicate with the interior of the rotating bar cylinder (1) as well as with the inclosed space surrounding the outer sta tionary bar cylinder (J) and with the trunk (C), as shown and described for the purposes herein set forth.
