ABSTRACT:
Objects such as apples are sorted by weight in an apparatus having a train of like sorting cars each pivotal about an axis perpendicular to the transport direction of the cars along a path above a plurality of sorting stations. Each car has a counterweight to one side of its pivot axis with the center of gravity above the pivot axis and is provided with a receptacle adapted to support an object to be sorted above and to the other side of the pivot axis. As the train of cars is moved downstream the counterweight sides are cammed upwardly by an upwardly inclined rail that shortens the moment arm of the counterweight side of the car and increases the moment arm of the object side until the car overbalances and dumps the object out at a sorting station. The camming rail may be constituted by a plurality of short rail sections hinged at points above the sorting stations and vertically adjustable at these points.
