ABSTRACT:
As parts of two different sizes are dropped into the mechanism, they are received by a rotor that rotates about an upright axis and is provided with a generally conical configuration such that the parts slide along the conical rotor in a radially outward and downward direction. The conical upper surface of the rotor is formed in part by fin-like members having uppermost longitudinal edges that define the sliding conical surface for the parts, the lateral spacing between such fins being such as to permit the smaller parts to drop between the fins and onto a lower conical surface, also sloping radially outwardly and downwardly from the axis of the rotor, while the larger parts remain supported by the fins. The parts thus sorted into a pair of vertically separated levels are driven by the rotor along a circular wall at the periphery of the rotor until reaching respective vertically offset outlets arranged to receive their respective larger or smaller parts by gravity feed from the corresponding portions of the rotor.
