Abstract
A machine for sorting objects, such as for instance mushrooms, depending upon the size of the object includes an elongated supporting frame, a continuous carrier chain extending longitudinally on each side of the frame, there being apparatus for synchronously driving the chains, and a plurality of spaced, transversely extending rods spanning the distance between the chains and carried thereby for movement therewith, there being a finger member carried by each of the rods in swingable engagement therewith, each finger member having an upper hook portion engaging the rod, a lower edge portion and an intermediate arcuate portion between the hook and the edge. A toothed guide strip is provided and extends longitudinally adjacent one of the carrier chains in a position to engage the lower edge portions of the finger members as they are moved longitudinally of the machine when the chains are driven, to impart vibrating movement to the finger members to thus facilitate the objects to be sorted in falling through spaces between the finger members, such spaces successively increasing in size as the fingers are moved from an object receiving end of the machine to the opposite end thereof, al…
