IMPROVEMENT IN GRAIN-SEPARATORS.

Specification forming part of Letters Patent No. 146,7S4, dated January 27, i874,- applioation filed March 27, 1872.

To all whom t may concern:

Be it known that I, FRANcIs W. ROBINSON, of the city of Richmond, county of Wayne and State of Indiana,`have invented certain Improvements in Grain-Separators, of which ,the following, taken in connection with the accompanying drawings, is a specilication.

My invention relates to providing the shoe of a grain-separator with an extension-board, secured to the spout at the `back end ot' the shoe, so as to extend under the front or lower end of the straw-stacker, so that by combining the shoe thus ext-ended of a grain-separator with the straw-stacker I produce a more perfect grain-separator, and not a Inere carrier of straw and ehaf, as heretofore.

Figure l is aside elevation of a section of my machine as seen with the siding-boards removed, showing the machine from the front of the shoe to the hinge ot' the straw-stacker. Fig. 2 is the spout of the shoe with an inclined board attached, as it appears when separa-ted from the shoe at the line X and viewed from the tail of the machine. Fig. 3 is a representation of the lower shaft of the straw-stacker with pulleys and knockers, which shake the upper tloor of the straw-stacker, producing an up-anddown motion.

A, the frame of the machine. B is the shoe, which is made as in ordinary separators. My improvement consists in providing said shoe with an extension-board, It, which is secured onto the spout Q at the back end of the shoe by means of screws, and extends back under the straw-stacker I), at its loweror front end,

i that it may receive all the grain that is car- I ried over with the straw, and shaken th erefroln onto the door F of the stacker l? by means of the downward passage of the slats of the carrier E. The straw-stacker is made as ordinary stackers in grain-separators, and a description is not deemed necessary, as it is a well-known device. O, pulleys; l), sides of straw-stacker; F, apron oriloor 5 G,belts, H, pulley; I, upright pieces; K, slanting board; L, hanging pieces; M, vihratin g pieces; 1 N, supports for the floor or apron F. 0 is one-halt' of a hinge; Q, spout ot' shoe; S, knockers; T, hangers for shoe l5. U are slats 5 V, slats; IV, battens; X, dotted line, showing shape Ofspout Q; Y, seive. Z are wires. 2 are slats; 3, floor. 4 are crosspieces; 5, stacker, broken'oii; 6, floor. As the most of these devices are well known, a further description is deemed unnecessary.

It will be seen that, as the straw is thrown `from the strawcarrier connected with the thrasher onto straw-carrier E of stacker 1, the grain falls through between the slats ot' carrier E, and is drawn and shaken down the iioorF ot' stacker I), and is received on the extension-board R, and rools or is gravitated into spout Q of the shoe B, from which it passes into a receptacle. I

I claim as my invention and desire to secure by Letters Patent of. the United States- The combination, with the shoe B, of the extension It, arr nged in relation to the strawcarrier, substantially as shown.
