IMPRVEMENT IN SMUT-MILLS.

Specification forming part of Letters Patent No.11117f7'98, dated February 24, 1874 application filed December 8, 1873.

To all whom t may concern.-

Beit known that l, KILIAN SCHWAB, of Lebanon, St. Clair county, State of Illinois, have invented an Improved Smut-Mill, of which the following is a specification:

This invention pertains to smut-mills for ther purpose of cleansing grain from its smut, impurities, and the like; and the constructive nature thereof consists, rst, in the combination of a fan-cylinder with a stationary smutter, the fan-cylinder operating so as to force the grain in its passage to be retained against the smutters; secondly, in the peculiarlyconstructed smutter, consisting of separate punched metal sheets, inclinely positioned and secured, and arranged in cylindrical form, to act as the smutter for the grain 5 thirdly, in the combination, with smutter aforesaid, of a stationary sievelike cylinder, through which the impurities from grain pass, 'ourthly, in the combined arrangement of the revolving tan-cylinder, and stationary parts, such as smutter, sieve-cylinder, and outer casing, with relation to each other, all of which will hereinafter more fully appear.

Of the drawings, Figure 1 is a sectional elevation; Fig. 2, a sectional top plan; Fig. 3, a top plan with part broken away 5 Fig. 4, a detail of -perforated cylinder.

Aisa strong, stout, and durable frame. At top and bottom the frame A has cross-supports a a', in which the journals of the power-shaft B are fitted to turn. The shaftB supports the fan-cylinder (l, so as to turn with same. The fan-cylinder C consists of top and bottom circular heads c (see Fig. 1) and the uprightfanblades c1. (See Figs. 1 and 2.) The top and bottom heads chave circular openings o2, (see Figs. 2 and 3,) to admit air through top and bottom of cylinder. The circular opening top of cylinder C has a rim projection, c3, Fig. 1, to prevent the grain which is fed top of said cylinder from fallinginto same, or through its said opening. The fan-blades c1 are secured in diagonally and relatively apart, (see Figs. 1 and 2,) and have their outer edges formed with teeth c4, the object of thus positioning the fan-blades o1 being to prevent the grain, during its passage through the mill, from being thrown or forced within fan-cylinder when same revolves, the teeth c4 of fan-blades being to act with relation to the smutter, to create the Z-like passage for the grain to pass, and also to equally cause said grain to be retained against said smutter. The smutter and sieve-cylinder are combined in one, and are stationary. Hence I provide, surrounding the fan-cylinder C, a frame-cylinder, D. (See igures.) The framecylinderD consists of upright frames d, united to top and bottom closing heads d1 d2. (Seeiigures.) The heads di d2 have provision left to leave o pen the circular openings c2. L To the inner side of framed cylinder l), I provide a wirenetted covering', forming the stationary sieve-like cylinder at. (See Figs. 1 and 3.) 'lhrough the openings of said sieve-cylinder the dust and impure particles of grain are sitted. The smutter E consists `of metal sheets @,so perforated as to present roughened edges, as indicated in Fig. 1. The sheets e, composing smutter, can also be ot' the modified construction, viz., as shown in Fig. 4c, with punched diagonally-serrated edges. The peculiar arrangement and attachment of punched metal sheets e, to form the stationary smutter here designed, are such as to achieve, with relation to the fan-blades c1 of the fan-cylinder, a Z-shaped passage for the grain. (See Fig. 1.) Hence I provide the frame-cylinder D with incline-shaped strips el, Fig. 1, to which each series of punched sheets e is attached. Thus secured, the bottom edge of each metal sheet e is inclined inward. Further, each under punched sheet e is so attached and arranged, with relation to its upper one, that the bottom edge of the first-mentioned projects below the top edge of the bottom or lastmentioned sheet, and as indicated in Fig. 1, the object of thus alternately secnring the punched sheets being to permit the grain, in its passage down the top sheet, to be turned under and back of the bott-oni edge of same, reach the top of sheet below, and thus follow the course through the winding or Z-shaped pass age created between the alternate punched sheets and the serrated edges of the fanblades o1. At bottom the smutter, or, properly said, the frame-cylinder bottom head d2, is lined with sheet-metal lining, leaving a circular rim,

e3, to rise above the opening of said bottom head, (see Fig. 1,) to prevent the cleansed grain passing out of said opening. ln fact,

the grain is fed to the machine through the slotted opening l*` at top; (see Fig. 3,) through the head d1 is passed from over the head top of fan-cylinder C; thence passed through the mill on the bottom head I? ot' frame-cylinder; thence is discharged out through the bottom slet or opening F. (Sec Fig. l.) It is the cylindrical smutter which, by means of its roughened edges, takes away from the grain its defective parts, and otherwise properly removes the smut and impurities. Also, it will be noticed that the fan-cylinder C is operated at same time with such speed as to produce a wind force sufficient to force and retain the grain in its passage against or to be passed over the smutter. I rely chietly upon sufricient fan action to accomplish this object. lThe Wind power is further utilized in forcing and otherwise causing the dust, impurities, and the like taken from grain to be passed through the sieve-like cylinder 6k To catch and receive the relnoved smut, dirt, and the like, I further provide a suitable cylindrical outer casing, G. The outer casing Gr surrounds the framccylinder D and its inner parts aforesaid, and can be made an entire cylinder, or, as here shown, (see Figs. l, 2, and 3,) to consist of foursectionalcylindersides,withflanged edges, to be attached properly to the frame A of the machine. At bottom, the opposite sides ofthe outer casing G can have suitable openings for the discharge of its contents. For different qualities of grain to be cleansed, the shaft B can be supported adj ustably, so as to be raised o1' lowered, thus raising and lowering at same time its fan-cylinder C, and consequently enlarging ornarrowing the passages for the grain, as required and deemed best.

Vhat I claim is- Y l. The stationary smutter E, having a series of inwardly-attached metal punched or perforated sheets, e, said sheets being so arranged that the bottom edge of the top sheets of each series shall partly project below the top edge of the next following series, as and for the purpose herein shown and described.

2. The combination of fan-cylinder C, con.- sistin g of top and bottom heads c, and fan-blades c1, having serrated edges c4, with stationary smutter E, consisting of perforated sheets c, substantially as herein shown and described.

3. The combination of a stationary smutter, E, having perforated sheets c, arranged as described, and sieve-cylinder d3, as and for the purpose set forth.

4. The combination of revolving fan-cylinder C, stationary smutter E, sieve-cylinder di, frame-cylinder D, and outer casing G', all said parts being arranged and constructed, with relation to cach other, as and for the purpose set forth.

In testimony ot said invention I have hereunto set my hand in presence of witnesses.
