UNITED STATES PATENT OFFICE.
GRANT savanna, OF CUYAHOGA FALLS, OHIO. 1
Specification of Letters PatentNo. 10,949, dated May 23, 1854.
T0 mz'tmayconcernw Be itknown that I, G. B. TURNER, of
Cuyahoga- Falls, in the county of Summit and State of Ohio, have inventeda new and improved implement for cleansing grain fromsmut and also for separating the chaff and light or imperfect grain from sound it, passes through this concentrator, while the grain is thrown by it to the center, and is made to pass through another set of plates to the circumference, and again to the center by means of the screen concentrator. The process may be repeated as often as desirable, the dust from each scouring passing through the concentrator, and the grain over it to the center. Also in the stationary and rotating scouring plates, and the combination of those plates so that either of them may be elevated or depressed, and thereby the distance be made to vary between them, in order to scour more effectually, or admit of the passage of a greater or less amount of grain. Also in the combination of the smut and separator.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction andoperation.
A, represents a rectangular frame, having at its lower part a fan, B, inclos'ed by a suitable box, C, which communicateswith a blast spout, D.
The blast spout, D, isplaced in a vertical position, and is straight the greater part of its length. The upper part is curved outward from the frame, A, and forms a double curve as shown in the drawing; a spout, E, being between the two curves, and projecting downward from the'blast spout, D. The blast spout, D, extends upward nearly the height of the frame.
F, is a vertical shaft, the lower end of which runs in a bearing, (a), on a crosspiece, F, of the frame, A. On this shaft, F, are secured, at a suitable distance apart, two circular scouring plates, G, G. These scouring plates are crimped or formed with a series of concentric steps or ledges, (12),
having small studs or spikes, (c), on their upper surfaces. Directly under each scouring plate, and also attached to the shaft,
F, there is a fan, H. Over each scouring plate, G, there is placed anotherscouring plate, I. The plates I, I, are stationary, and are secured to the frame, A, in any proper manner; They are crimped or have ledges, (b), and studs, (0), and are constructed precisely similar tothe plates, G, G.
J, J, are inverted conical screens, which are stationary, and inclose the fans, H, H, plates, G, G, and the lower surfaces of the plates I I; the screens being attached to rims, ((2), (cl), which encompass the edges of the stationary plates, I, I. The upper screen leads into, or communicates with the lower screen, a circular aperture being at the center of the lower plate, I, as: shown in the drawing. At the center of the upper plate, I, there is a hopper, K; and at the upper end of the vertical shaft, F, there is a pulley, L.
Operation: The grain to be separated and cleaned from smut, is placed in the hopper, K; and motion is given the shaft F, plates, G, G, and fans, H, H, by a belt which passes around the'pulley, L. The grain passes between the two upper plates, I, G, and, by centrifugal force, is discharged at their peripheries, and is conducted by the upper inverted conical screen, J ,to the lower plat-es, I, G; the upper fan, H, blowing out,through the screemthe dust and smut scoured from while the unsound grain, which is somewhat heavier, falls through the small. spout, E, upon the ground, as shown by arrows, The sound grain passes down the blast*sp0ut,-'D, and then passes out of an opening, N, at the lower end of the fan box, C, as shown by arrows, The rotating plates, G, G, and fans, H, H, are
moved by a separate belt, or by a motion in dependent of that given to the fan, B; as will be seen by referring to the drawing, the red lines showing the fan-belt and pulleys. The relative speed, therefore, of the fan, B, and scouring plates, G, G, and fans,
grain in passing down the screens, J, J
and the grain and chaff alone enter the spout, D, the chaff being separated from the grain in the spout. By this arrangement, the different parts are kept separate, viz., the smut and dust from the chess or The machine is simple, not liable to get out of repair, and will perform its Work effectively.
I do not claim the crimped circular scouring, plates, G, G, I, I, nor any other of the within described parts, separately, for they have all been previously used separately; but
What I do claim as new and desire to secure by Letters Patent, is
The stationary and rotating scouring plates, G, G, and I, I, inverted conical screens, J, J, and the blast-spout, D, constructed, arranged, and operating, in the manner and for the purpose substantially as shown and described.
