ABSTRACT:
A feed screw for use in a rectangular bin outlet permits uniform feed from the bin along a length of the screw. This is achieved with a screw of uniform pitch on a shaft comprising a plurality of coaxial and contiguous cylindrical sections having progressively decreasing diameters dimensioned so that the differences in volume capacity between each pair of contiguous sections are equal over such length.
