wINNoWEE,
Specicaton of Letters Patent VNo. 10,155, dated October 25, 1853.
To all whom t may concern: g
Be it known that we, DAVID S. MACKEY and JAnvIs R. SMITH, of Batavia, in the county of Genesee and State of New York, have invented certain new and useful Iniprovements in Grrain-Separators; and we do hereby declare that the following is a full, clear, and exact description of the construction and opera-tion of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a longitudinal vertical section of the separator, taken through the center. Fig. 2, is a section showing the eccentrics and blocks by which the screen is operated.
Similar letters of reference indicate corresponding parts, in each of the two figures. The nature of our invention consists z- 1st. In a peculiar manner of operating the screen, viz, by means of two eccentrics working between blocks attached to the under side of the screen.
2d. Our invention consists in having two A, represents the hopper, in which the grain is placed.
B, is the screen, on which the grain falls yfrom the hopper.
The screen is suiiiciently coarse to allow the grain to pass through it, but will prevent coarser articles. These coarser articles fall off the screen at its outer and depressed end; the screen being somewhat inclined. The screen has a vibrating mot-ion communicated to it, by means of two eccentrics, C, and, D, which are placed on a shaft, E, underneath the front end of the screen. These two eccentrics work between two blocks, (a), (b), attached to the under side of the screen; as seen in both figures. The eccent-rics are of elliptical form, and each one acts against a block; the eccentric, C, working against the block, (a) and the eccentric, D, against the block, (b). The eccentric, C, when it acts against the block, (a) throws the screen forward; and the eccentric, D, when it acts against the block, (b), throws the screen backward. Now, as the eccentrics are placed in a reverse manner upon the shaft, E, it naturally follows that the screen will have a reciprocating motion communicated to it.
F, is a fan, placed in a bo-x, G. The box and fan are placed underneath the back part of the screen, or screen frame. The box, G, is provided with'two apertures, (c), UZ); the aperture, (c), being at the upper part of the box, and the aperture, (d), at the lower part. The box, G, is of an irregular circular shape, so that two blasts may be obtained from the same fan. This will be understood by referring to Fig. l. The fan rotates in the direction indicated by the dotted arrow; and the arrow, No. l, shows the direction of the upper blast, and the arrows, 2, the direction of the lower blast. The upper blast passes over the top of the screen, and carries off the chaif and other light particles; while the lower blast passes upward through the screen, and prevents the chaff from settling upon the screen, and thereby prevents the said screen from being clogged.
The two blasts therefore cross or intersect each other.
The grain, after passing through the screen, falls upon the inclined plane, H; which forms the bottom of the box, I, which incloses the fan-box. This inclined bottom or plane, H, conveys the grain into a blast spout, J, at the lower end of which is placed a fan, K, inclosed in a suit-able box, L. The fan, K, rotates in the direction indicated by the dotted arrow; and the arrows, 8, show the direction of the blast. The grain passes down the blast spout, J, and out at the aperture, (e), at the botto-m of the blast spouts; theJ blast forcing all light matter upward and out of the upper end of the blast spout.
In the upper part of the blast spout, there is a partition, (f), the lower end of which does not quite touch the outer side of the spout, but leaves a small passage, as seen at, (g). The outer side of the spout is provided with a small valve, (71), by which the opening, N, between the partition, (f), and outer side of t-he spout, may be made larger or smaller, 'as desired.
The light screenings which possess too much gravity to be blown out at the end of the spout, J, fall through the passage, M, upon t-he floor; while the heavier screenings fall into the opening, N, and pass through the passage, (g), into'the blast spout, and are thus subjected a second time to the blast.
By regulating the valve, (h), all but the heavier screenings are prevented from entering the passage, N.
Thus by the foregoing improvement, the grain is perfectly separated, the screen prevented from clogging, and a reciprocating motion is given to the screen, by an extremely simple device, attended with very little friction.
Having thus described our invention, what we cla-im as new, and desire to secure by Letters-Patent, is,-
l. The peculiar manner of operating the screen, viz, by means of the eccentrics, C, D,
