To all whomit may concern.-

Be it known that we, WILLIAM N. SHARP NAOK and MicHAnL MoMArioN, citizens of the United States, residing at .Bucyrus, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Separators and Sinutters; and we do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it ap pertains to make and use the same.

Our invention relates to machines for cleaning grain from smut and other refuse.

The principal object of our invention is to produce a better circulation of air around and through the smntter. Another object is to improve upon the means for scouring the grain.

Our invention therefore consists of constructions and combination, all as will hereinafter be described and claimed, whereby the desired results are accomplished, reference be ing had to the accompanying drawings, in which- Figure 1 represents a perspective of our separator and smutter; Fig. 2, a longitudinal section through a separator and sinutter, the upper part of the separator not being shown; Fig. 8, a transverse section through theseparater-case; Fig. 4-, a side elevation, and Fig. 5 a section, of the metallic brush.

A represents the separator case, A an equalizing-valve, A shelves below the equal- L IO o i O izing-valve, A a fan-ease having outlet a and inlets a a, A" a fan, and a hopper having spout a all of which are shown in an application, No. 108,042, filed by us on October 3, 1883. No claim is therefore made in this application to those parts.

3 represents a secondary ease or extension of case A, and consists of a front wall, B. side walls, B 13, and semi-cylindrieal cover B, and is connected with the interior of case A by an opening or passage, B- Upon the ends of case B are seini-cylindrical flanges b, which close the ends of semi-cylindrical cover 13". This cover is made of metal or wood, preferably elastic, and is attached by its rear end to the cross-piece I) of case B, or the wall A of case A. The front end is attached to crosspiece I) of caseB in such a manner as to leave a space, 1), between said parts. The preferred mode is to attach it by means of set-screws I), so that the space I) may be increased or lessened in height at pleasure for the purpose of regulating the draft of air at this point. The front wall, B, is provided with an opening, I), provided with a gate, door, or valve, 1), which can be opened or closed to any extent when it is desired to regulate the draft through opening The cylinder 0 is suspended in case Bin any suitable manner, and fits closely to the crosspiece b-,to prevent the air in the lower part of the case from passing in front of the cylinder. The erosspiece Z) is separated from the cylinder by a space, If, to connect the passage B with the chamber I) below the cylinder. The passage B is formed by the cylinder 0 and the cover B, and is used for the circulation of air around and through theupper part of the cylinder. The air admitted to thispassage passes through opening or space 7)". Through the cylinder extends a shaft, C, on which are the boaters and brushes Gflwhich will presently be described.

In all smutting devices that we are aware of the fan and fan-case are placed in such position in relation to the smutter that the draft or'suction passes obliquely through the cylinder. In such cases part of the cylinder is not reached by the air. \Ve propose to remedy this by placing the fan in such a position that the air will pass through every part of the cylinder, and it is accomplished by placing the fan immediately in the rear of the sinutter,

with the length of the fan-case parallel with the length of the sinutting-cylinder. One means for accomplishing this is shown in the drawings, and consists of a fan-case, A, located in a chamber, A, and having its length parallel with the length of the cylinder, and inclosing the fan A, mounted on a shaft, A, which is parallel with the "fan-case and cylinder. The air sucked through openings 1) and 1) passes around and through all parts of the 9 5 cylinder, and is drawn into the fan-case and projected into the dustroon1 through exit a. By making the openings a at the ends of the fan-case the air is sucked through all the perforations of the cylinder, even to the very ends. By making the draft-opening into the fan-case parallel with its length the same result will be accomplished.

The brushes 0 are formed with metallic bristles 0, attached to bases 0 in any suitable manner, and are attached to spiders radiating from the shaft 0. Each spider-arm is provided with projections or arms a", which inclose part of the brush and prevent undue strain upon the base. Below the arms are bridges c and 0", having openings 0", through which the screw-threaded stem 0, of brush 0 projects. Between bridges 0 and 0" is an adj usting-nut, 0 and below bridge-cis a clamping-nut, c \Vhen the bristles 0 become worn, they can be projected nearer the inner circumference of the cylinder by revolving the clamping-nut c asufficient distance below the bridge 0" and revolving the adjusting-nut 0 until it raises the brushes to the proper point.

The operation of the device is as follows: The fan, heaters, and brushes being revolved in any suitable manner, the grain is passed from the separator to the smutter by means of passage D. The airis drawn by the fan through opening or space 1) into passage B and part passes through the perforations on the front side and out through the perforations of the cylinder in the side nearest the fan. The rest of the air passes around the cylinder and through space or opening I) to chamber b from whence it is drawn into the fan. If desired, the amount of air drawn through opening or space b maybe regulated by adjusting the front end of cover B. The bottom of the cylinder is deprived of its smut and dirt by and an exhaust-fan located behind the cylin der, substantially as described.

2. In a separator and smutter, the combination of a smutting-case having a cover provided with means for regulating the size of the opening between the top of the case and cover, a suction device, and a smutting device interposed between'the suction device and front of the case, substantially as described.

3. In aseparator and smutter, the combination of a smutting-case, asmutting-cylinder in said case, a cover over said case and cylinder, forming passage B and opening b and provided with adjusting. set-screws for regulating the height of opening I)", and a suction device, substantially as described.

4:. In a smutter, the combination of abrush having screw-threaded stem 0 and nuts 0 and 0 and a spider-arm having arms 0 and bridges c 0. provided with openings 0, substantially as described. I

Iii-testimony whereof we aflix our signatures in presence of two witnesses.
