Title: Threshing apparatus

I claim:

1. Apparatus for threshing grain material and separating the threshed grain from the residual grain material comprising:

(a) an elongated supporting frame,

(b) a shaft extended longitudinally of and rotatably supported on said frame,

(c) a threshing unit mounted on said shaft for rotation therewith including a tapered cylindrical body member having a continuous peripheral surface and a rub bar helically extended about said surface,

(d) a rotatable grain separating cylinder having a peripheral surface tapered over the axial length thereof,

(e) means for rotatably mounting said separating cylinder on said frame in a coaxial concentrically spaced relation about said threshing unit, to form a threshing zone therebetween having an inlet and an outlet, said cylindrical body member and separating cylinder being substantially coextensive in axial length,

(f) concave grates and separating grates arranged circumferentially of and over substantially all of the peripheral surface of said grain separating cylinder,

(g) means for rotating said threshing unit and grain separating cylinder at relative rotational speeds,

(h) means for supplying the grain material to be threshed into the inlet of said threshing zone, with the clean grain in the threshing zone being moved through said concave grates and separating grates by centrifugal force, concurrently with the travel of the grain material from said inlet toward said outlet,

(i) means for collecting the clean grain passing through said separating cylinder, and

(j) means for removing the residual material only from the outlet end of said threshing zone.

2. The apparatus for threshing grain according to claim 1 including:

(a) means for relatively axially moving said separating cylinder and threshing unit to uniformly vary the transverse spacing therebetween.

3. The apparatus for threshing grain according to claim 1, wherein:

(a) said concave grates and separating grates extend longitudinally of said separating cylinder over substantially the full length thereof and in an alternate relation circumferentially about said separating cylinder.
