SMUT-MACHINE FOR CLEANING GRAIN.

Specification of Letters Patent No. 890,`daited August 23, 1838.

To all whom it may concern Be it known that I, JOHN PARKER, of Sunbury, in the county of Delaware and State of Ohio, have inventedA as new and useful Improvements in Machines for Cleaning Grain from Smut and other Substances, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

This machine consists of a suitable frame A, Figure 1, having a vertical shaft S turning in the center thereof by means of a band B and pulley C, on which shaft'are fastened four or more curved wings D, Figs. 2 and 4 made of sheet iron and punched in rows of inclined openings, the roughened surfaces being from the center, which shaft and wings are surrounded by a sheet iron cylinder E, punched inward toward the center in oblong apertures inclining about 550 and in parallel rows,A the roughened surfaces, of course, being toward the center. This cylinder is closed at top and bottom except at spaces F and G for the admission and discharge of the grain, &c., Figs. 5 and 6. The upper space F is surrounded by a hopper N for the admission of the grain and the lower one G by a vertical spout O, which leads int-o a horizontal trunk T placed below the cylinder and on one side of the shaft of the wings curved at one end and straight at the other. In the curved end is a revolving fan H, Fig. 3, turned by a band I passed around its axle and around the pulley of the before mentioned center shaft. The bottom of the trunk is closed, except at two places where it is left openone of the openings K is immediately under the fan and the other, L, is about the center of the trunk. From this opening to the discharging end the bottom is made to incline upward, as

Operation: The cylinder and fanfbeing put in motion at the rate of about 500 or 60() revolutions per minute the grain, &c., is put into the hopper by which it is conducted to the inside of the cylinders where it is met by therevolving wings which dash it violently against the sides ofthe cylinder and protuberances therein which has the effect of breaking off the smut from the grain a great portion of the former being driven through the intestines of the cylinder and the latter with part of the smut falling into the trunk below, where it is met by the current of air produced by Athe revolving fan which drives the remainin having the side of each wing which is fastened to said shaft made straight and then curved backward from the shaft to its outer extremity and braced by arms radiating fromthe shaft, to the ends of which the curved wings are fastened as herein described.
