Agitator for an axial flow cylinder

Abstract From the Canadian patent

A cylinder cage of an axial flow combine has radial openings about its circumference permitting threshed material to leave the cage as the threshing cylinder is rotated. An agitator mechanism is provided to dislodge threshed material tending to accumulate on the top side of the cylinder cage. Once dislodged, the threshed material will fall to a distribution auger which in turn delivers the threshed material to accelerator rolls disposed beneath the threshing cylinder and cylinder cage. The agitator includes a plurality of curved ribs or fingers spaced axially along and adjacent the outer periphery of the cylinder cage. The agitator fingers are rigidly secured to a backbone member which in …
