JESSE TAYLOR, OF AUBURN, NEW YORK.

SMUT-MACHINE.

Specification of Letters Patent No. 5,503, dated April 11, 1848.

To all whom it may concern Be it known that I, Jnssn TAYLOR, of the town of Auburn, county of Cayuga, and State of New York, have invented certain new and useful Improvements in the Manner of Constructing Machines for Separating Smut and other Dirt fromNVheat and other Grain, called Taylors Improved Smut-Machines, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

Figure l, is a perspective view of the machine as arranged for operation. Fig. 2, is a longitudinal section on the dotted line 00 w of Fig. 3. Fig. 3, is a vertical transverse section on the line 0, 0, of Fig. 2. Fig. l, is a view of the inside of the head of the concave showing the ribs thereon.

turns opposite to the ribbed head Fig. 4. Fig. 6, is a section of the inside of the concave or stationary case. Fig. 7 is a view of the outside of the revolving rubber. Figs.

The general feature of the smut machine are like many others in use, so far as they relate to its being composed of a rectangular frame containing a stationary cylindrical concave roughened on the inside, and a revolving cylindrical rubber with inclinedv beaters on its outer surface, an inclined trough for introducing the grain, a spout for discharging it, and-a fan for blowing the dirt from the grain, arranged, however, differently from the same parts in other machines.

The first and essential improvement that I have made in the machine, and for which I solicit Letters Patent, consists in producing two currents or blasts of wind simultaneously from the same rotary fan combined with the machine, one of the blasts being longitudinally through the entire length of the cylindrical concave and parallel with its axis and around the outside of the revolving rubber, and out through an upright tube at the feeding end into which the inclined feeding spout leads, for separating the loose dirt from the grain as it passes into and before it enters the machine through said tube from the feeding hopper, and the smut separated from the grain in subsequent-1y passing through the machine, and the other, or transverse blast, crossing Fig. 5, is a view of the outer end of the rubber which- The second improvement consists in the mode of making the revolving rubber by attaching the beaters or rubbers for beating the smut from the grain, to the ends of the radial arms of the revolving cylinder, by

oblong mortises in the ends of the radial arm (or in the beaters as preferred) and screw bolts and nuts for the facility of adjustment, so that they can be brought nearer to a receder further from the inside 'of the concave as required, and arranging said adjustable beaters in oblique parallel lines, inclining about ten degrees from the line of the axis of the cylinder, previously covered with sheet iron to preserve the grain in its proper place while passing through the machine. The obliquity of said blades or beaters causing the grain to be forced spirally against the pressure of t-heinternal blast of wind toward the discharging end. The teeth on the edges of the blades or beat ers which are in the form of Fig. 8, in the drawings, serving to cut the smut from the grain and the plain portions to polish the grain. outer edge of the blades or beaters, forming oblong teeth in the form as above mentioned the remaining portions of the beaters, about half their length next the smooth end of the concave are made plain and smooth.

The end of the rubber next and opposite the fluter and ribbed end of the concave is made with radial ribs or Wings radiating from the center for striking the grain and throwing it against the ribs on the end of the concave for breaking the smut from the gram.

The radial wings also increase the draft in the machine for blowing the smut out through the upright tube into which the inclined feeding trough is inserted.

The notches are made in the The third improvement consists in the the head next the discharging end plain, and

having it constructed of suflicient length to form a space next the discharging end for the grain to enter previous to the separation of the remaining smut therefrom by the transverse blast of wind from the fan. The stationary cylinders of cast iron in two half circles with the teeth and ribs cast on the same. The teeth being in form of Figs. 8 and 9, in the drawings, Fig. 8 being a front view of one of the teeth and Fig. 9 being a side view of thesame, being cast to a point which renders them hard and not liable to rubber and fan are made to revolve simultaneously. The operation of the machine having been described in explaining the nature of the machine need not be repeated.

I do not claim making a smut machine with a stationary ribbed concave and revolving rubber of oblique heaters, revolving fan and tubes, or spouts for the admission and discharge of the grain, smut, dirt, &c., except in the manner above described, as these have heretofore been constructed and com bined in various ways.

A, is the frame made of suit-able size,

strength and material; B, the concave fixed in the frame; C, the revolving rubber; D, the fan; '13, the upright tube at the feed end of the concave, the lower portion of said tube being curved inward andinserted into ,of the concave between the said concave and the receiver.

H, is an inclined spout for conveying the cleaned grain to the receiver below the concave or in some convenient place.

I, is a curved spout leading from the fan to the interior of the concave for directing the longitudinal blast of wind through said concave.

J, is a curved tube also leading from the fan under the concave for directing the transverse blast of wind between the receiver and the discharging point at the lower surface of the concave.

K, is the fluted or ribbed head of the concave.

L, is a section of the interior of the concave showing the rubbers therein.

C is one of the notched blades or beaters 7 made of band iron or steel of the thickness of one-eighth of an inch attached to the arms of the revolving cylinder. See Fig. 10 of the drawings.

What I claim as my invention, and desire to secure by Letters Patent, is'

Making the rubbers and concave with a notched and smooth portion in the manner and for the purpose above set forth.
