To all whom it may concern Be it known that we, GEORGE F. METZGER and JAcoEP. KoHLE`Eof West Fayette, in the county of Seneca and State of New York, have invented a new and useful Separator for description, reference being had to the accompanying sheet of drawings, which forms part of this specification. `Our invention relates to that class of separators used for separating the stems of clover from the chaff, and removing and .cleansing ter described. e

Inthe accompanying drawings, Figure lis lA is an extra spout. A is a sloping board, called a chute, and is connected by side boards, which incline toward each other, andare represented by a c in dotted lines in Figi 2. The bottom edge of A is seen in Fig.` 2, in dotted permit the clover-seed and retained chaiI to pass into the sieve B.` B represents the Vupsieve, B', over the chamber, and the bottom of solid board, with a slit-or opening, b, at the front end, for the"` passage of the' seedinto a second chamber below, marked D, ,where the seed to fall through the sieve into the lowest chamber, marked E', which has a sloping E are `all framed and attached, as shown in Fig. l, and suspended by links to four posts on the supporting-frame, which sustains the whole apparatus. rlhese links are seen in Fig. l in the dotted lines cc. These links direction of the arrows in Fig. 1, and this motion is given by a connectingrod, C, in Fig. 2, which is moved by the crank of the fanshaft C 5 or the same may-be moved by any proper gearing to any desirable part of the separator, the power of which will work the stem-separator. Fand F' are fans. F" is a by a partition, f. The bottom of this trough 1s sloping across the separator. The top line is seen indotted lines at f, and thelowest at j" in dotted lines, while the solidlines at'f show the section on a: w of Fig. 2, which is the middle of the frame. G is the upper side of an ordinary clover-separator. G is the sieve the posts and sides of the clover-separator, as A seen at d d in Fig. l. On these `rods d d p the clover-separator can slide t transversely in `the direction of the arrows in Fig. 2., and this motion is communicated by a connecting-rod, I, which is operated from the crank of fanshaft C! througha bell-crank lever, J, and a rod, K, which is fastened to theside of the separator, by means of which the separator slides back and forth, as indicated by the arrows in Fig.` l. The clover-separator and stem-separator attached are supported on a frame consistingof four posts, L L L L, which are held together by rails L on the sides and` ends. e

The operation of the stemmer, attached to a clover-mill improved, as above mentioned,-

by the. feature of the spout'A,-is as follows: The seed intended to be cleaned is thrown upon the sieveG, and-the machine is put in motion. It partially separates the seed, and the same falls through to the bottom board H, the ground chail being blown away by the action of the fan F. The unground. chaff is thrown over into the trough F. .The remaining seed and stems pass throughthe spout A,

and fall upon the sieve B `of the stemmer, i

while the seed, which falls through the `sieve G uponfthe bottom board H, is conducted through the opening A, and falls also upon vthe sieve B of the stemmer. The seed then sifts through the sieve B', separated from ,thel l stems, and falls upon the bottom board B, and is conducted through the opening b upon the sieve E, through which it falls upon the bottom yboard E', and on the same to thebpening e', where it falls into a box or other conve ient receptacle for the same. The fan F cleans the seed' upon the sieve E, and it falls y upon the bottom'board E perfectly cleaned. By the operation of the stemmer attached to' au ordinary clover-mill, with the improvement of the spout A, it .will secure all the seed and separate the stems fron; the same as fastas 4 hulled. The spout A is intended t0 be at- L tached, substantially as described, and shown in Fig. 1, to any ordinary clover-mill, for-the purpose of conducting` the seed and stems to the stem-separator. Theolover-mill, with the stem-separator attached, does 'not require as much power to Work it'as an ordinary clovermill, for the reason that the stems are disposed of Without being ground over and over j until it'beeomes light enough to be blown away by the action of the fans.

Having thus described our invention, what we claim, and `desire to secure by Letters Patent, is-.

The spout A, in combination with the sieve G', chute A', opening A", bottom board H,A and fau F', substantially as and for the purpose described.

2. In combination with the fan F' and upper separator-shoe, consisting of sieve G',

spout A, chute A', and bottom board H, arranged substantially as described, the 4sieve B' arranged to receive the separated material' from the upper shoe, substantially as set forth.

3. .The combination, in a clover-separator, of,y

the sieve B', shaking-board B', yarranged to leave the `discharge-aperture at the end nearest the blast, the sieve E, chute E', and

fan F, substantially as and for the purpose
