Abstract

See full text

An improved concave for use on a combine has a plurality of spaced-apart bars mounted parallel to the axis of rotation of the combine cylinder and at an angle with respect to a radial line passing from the center of the cylinder through each of the bars. The angle of inclination of the bars increases progressively from the intake end to the discharge end of the concave. The passageway between the concave and the cylinder also becomes progressively smaller from the intake to the discharge end of the concave. The angle of inclination of the bars aids the passage of grain between the bars and reduces resistence of the bars to the passage of grain therebetween.
