THRASHING-MACHINE. 119 the cylinder upon which are placed the four projections or beat- ers cccc. The cylinder revolving with great rapidity, the beaters act upon the unthrashed corn, as it is firmly held by the fluted cylinders, and beat and detach the seeds and husks from the stems. The whole passing over the cylinder, is thrown forward in the direction shown by the arrows xxx. It is first acted upon and shaken by the four rakes EEEE, placed upon the hollow cylinder D, moving in the direction of the arrow y. It is then thrown forward, and acted upon by an equal number of rakes, placed upon the circumference of the sparred cylinder I, and by them it is thrown out at the end of the machine, at L. The bottom of the machine FGH, is so formed with spars, or a species of wire-work, that, while the straw is carried for- ward by the action of the rakes, the detached grains of corn and chaff fall down in the direction of the arrows zzzzz, into a machine below, in which, by the action of winnowing, the chaff is separated from the grain. The first of the revolving cylin- ders D, is formed of thin iron, or of wood covered with tin. Fig. The second of the cylinders I, is of wood, sparred, so that any corn or chaff, not separated by the action of the first rakes, may fall through in passing over the last cylinder. The rakes at the.
