IMPROVEMENT IN SEED-SEPARATORS.

Specification forming part of Letters Patent No. 195,053, dated September 11, 1877; Reissue No. 8,715, dated May 13, 1879 application iled March 15, 1879.

To all'tuhom t't may concern:

Beit known that I, HiRAM STANDIsH, of Joy, in the county of Mercer and State of Illinois, have invented a new and useful Improvement in Seed-Separators, of which the following is a specification.

The present invention consists in novel means for taking the grain from the vibrating riddles, and delivering it evenly to ,two rotating screens.

In the drawings, Figure l is an end elevation of a seed-separator embodying -my invention, a door being open to show more clearly the construction. Fig. 2 is an elevation of the opposite end of the separator -from that shown at Fig. l, a door at this end also being open to show the screens. Fig. 3, Sheet 2, is a horizontal section of a part ofthe separator. Fig. 4 is a central transverse section of the separator.

Arepresents a blast-fan, driven by a belt from drive-pulley G, running on a pulley, H, on the shaft of the fan. A small pulley, T, dotted lines, Fig. 1 carries a belt passing over pulley R, Fig. 3, and a belt runnin g over 'pulley R', Fig. 3, and over pulley R", drives the shafts of the rotating screens. S, Fig. 2, indicates the means for actuatingthe riddleshaker. All of the parts have the ordinary construction of seed-separators, except as hereinafter described.

The means for conducting the seed in even quantities from the riddles B, Fig. 4, to l[he respective screens F consists of a chute-board, C, semi-cylindrical trough D, double-inclined chutes L, Figs. 1 and 3, troughs M M, and divider E.

The trough D is made semi-eylindricalin cross-section, that the greatest depth of seed may be centrally therein, and moved with the least friction to a Wedge-shaped divider, E, placed in the delivery end of the trough, to

conduct the seed in equal parts, respectively, to the screens by means of the inclines L and troughs M. The trough D, being attached to the shoe C, has a vibratory movementwith it, and consequently facilitates the proper movenient of grain inthe trough as fast as it comes from the riddles, whereby the rotating screens are evenly fed, so as to Work to their fullest capacity. The rotary screens F have their peripheries formed of wire-cloth of such sized meshes as to separate the finer from the coarser seeds in the ordinary manner of seed-separators, and the riddles B have also the ordinary construction, except they have a much less breadth in their measurement on a line taken transversely to thev fan-shaft. The operation is similar, in so far as attention is concerned, to other seed-separators, the seed being putin the hopper and the fan put in motion, which, by the aforementioned belts and pulleys, iinparts a proper motion to the riddles, screens, chute, and trough D, vthe separated seeds being spouted oft' in the usual manner.

I claim and desire to secure by Letters Patent- 1. The semi-cylindrical trough D, attached to the chute C, so as to have a vibratory movement, and provided with a wedge-shaped divider E. fordeliverinfr seed in e ual nantities to the screens F, respectively, as and for the purpose set forth.

2. The semi-cylindrical trough D, attached to the chute-board C of the vibrating shoe, and provided with a Wedge-shapeddivider, E, in combination with the double incline L, troughs M, and screens F, substantially as described.
