To all 'whom t may concern:

Be it known that I, J AcoB BEI-3mi., of Mifflintown, in the county of J uniata and State of Pennsylvania, have invented a new and Improved Winnowing-Machine for Separating Impurities and All Foreign Substances from Grain; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l, is a top view; Fig. 2, is a side elevation; Fig. 3, a vertical longitudinal section, and Figs. 4, and 5, are portions of the same detached.

L, is the concave inclosing the fan;p, p, are the Wings of the fan; 11 is a pinion on the fan shaft; m, is the driving cog wheel working into the pinion n; 7c, is a crank on the axle of the driving cog wheel.v

A, is the shoe in which is placed the screen J. The shoe is the entire width of the machine; its sides pass into and work in openings in the side casings of the machine; by which arrangement screens V.of much larger size than usual can be made use of, and the entire blast of the fan'can be concentrated upon the screens-there being no openings at the sides of the shoe, for the The shoe is suspended by the hooks e, at its front end, and is supported by the vertical springs h, at its rear end; it receives a horizontal longitudinal reciprocating mot-ion from the pitman F, operated by a crank on the fan shaft.

E, is an inclined board, the ends of which are let into and secured to the sides of the shoe A. The inclined board E, forms the bottom of the hopper, and has recesses cut in, its upper surface forming l abrupt shoulders o, o, rising one above the other in regular succession. The object of the shoulders in the inclined board E, is to regulate the feed of the grain from the hopper to the screen J, and t0 prevent the straw and chaff mixed with it, from clogging and choking the passage from the hopper, the first time the grain is passed through the machine; which they eect in consequence of the forward and back reciprocating movement of the shoe, thus enabling the shoulders on the inclined board E, to take hold of the chaff and grain, and force the same out of the aperture in the hopper on to the screen J.

After the grain has been passed once through the machine, and separated from straw and chaff; the false bottom D, is placed in the hopper, and the feed is regulated byv the adjustable gate S. The grain chaff, and straw, falls from the inclined board E, on to a series of vibrating arms (Z, d, forming a separator for removing the straw and chaff from thel grain, previous 4to its falling upon the screen. The curvedV wire arms d, cl, are inserted into the shaft c,

yhaving its bearings in the sides of thelshoe A. The shaft c, reciprocates with the shoe A, and is vibrated on its axis by means of a crank f, on the end of the same, and the vertical pitman g, jointed to the horizontal pitman F; yconsequently the separator has at the same time a compound reciprocating, and a vibratory motion, by which it is enabled to throw the straw upward and rearward out of the machine. ,The grain falls'VV from the screen J, on to the apron B,which conducts it to the front of the machine.

J ,-is a screen let into and forming a part of the apron B; CQC, are a series ofthin slats placed over the screen, J and secured by joint pins at each end ofthe same; the outer edges of the slats are connected to each other vby a` cordV a, by which they can be elevated` and retained on their edges; or can be Ydepressed and retained in a positionparf allel Vwith the-screen J. When the slats are y depressed, they completely cover the screen, and allow the grain to-pass freely over the slats ;'when they are elevated, kthey allow the grain to Vfreely fall upon and pass over the screen J. When the grain is not sufciently cleaned by the' vibrating screen or screens, the slats C, kC,are elevated frfor it to receive the benefit .ofthescreen J.

H, `is the screen or tail box under the screen J K, `is a gageboardinftherear rend of the. machine, for catching the tailings and head-v ings. y

' Having thus fully described my improved winnowing machine, what I claim therein as new and desire tosecure byjLetters Patent, is-
