To all whmn it may concern;

Be it known that I, WILLY Hameln, Germany, have invented an Improved Seed-Separator, of which the following is a specification.

reference to an appa- This invention has ratus for separating the spherical grams of plants, sand and other impurities from wheat and other grain as well as for sorting the different kinds of wheat by employing an endless band which replaces the usual sieves.

In the annexed drawings, given by way of example, is shown a form of an apparatus constructed according to this invention.

' Figure 1 is a longitudinal section of the aparatus. Fig. 2 is a cross section of same. Fig. 3 is a plan view of a portion of the sorting band and Fig. 4 a cross section of this band.

The apparatus comprises a reciprocating sieve frame a carrying inclined sieves b, be-

neath which a wide metallic endless band or belt 0 travels over rollers, and 1s provided with recesses d, in the form of pockets. This band travels slowly between the sides of the sieve frame in the opposite direction to the gravity movement of thegrains to be separated. given to the sieve frame known mechanism.

The feed hopper e for the grain to.be treated is furnished with a feed roller f in a well known manner and delivers the grain upon the inclined sieve b. As the grain asses over the sieve, the smaller grains which it is desired to remove fall'through the sieve holes upon the band 0 the sizes of the holes in the latter being chosen according to the grain to be sorted. The spherical grains or smaller grains are received according to their size and shape and are conducted to the rear, where they drop out at 113, where the endless band travels around the driving drum. The larger sorted and cleaned grain drops out at g, at the lower end of the band.

by any suitable MEY R, of i from being carrie A jerky reciprocating motion is the smaller grains separated d to the front, a transverse scraper h is arranged near the uppler end of the band. This scraper it allows t e smaller rains which lie in the recesses 11 to pass while holding back the grains which are to pass to the outlet g. The metallic band is furnished with a brush t which assures the cleanliness of the sieve b by passmg along the under side thereof.

To prevent The metallic band with recesses can be replaced as shown in Flg. 1 of the drawing, by strips of metal formed with recesses bored or punched, andfixed upon roller chains. The

and can also be formed of a plate of steel or copper furnished with punched recesses and fixed upon a belt. These two forms of the band are only given as examples and same can be varied as required.

Having now fully, described my invention what I claim and desire to secure by Letters Patent, is

In an apparatus for se arating grain, a metallic transporting end ess band having recesses forming pockets, and mounted in an inclined sieve-frame having a jerky reciprocating movement, sieves arranged above sai band, a scraper arranged transversely of said band and adapted to ermit the passage of the smaller grains whi e preventing the passage of the larger grains, means for driving said band in a direction opposite to the gravity movement of the grain thereon, and a brush secured to said band and adapted to clean the under side ofone of the sieves carried by said frame.

In testimony whereof I have hereunto set my hand in presence of two witnesses.

WILLY MEYER.

In witness of LEONORE RAson, H. HALL HALL.
