  • Patent number: 6752583
    Abstract: A material segregation and delivery apparatus is described in which a frame carries a succession of material receiving containers. A material intake station is situated above one of the material receiving containers. A number of endless belt conveyors extend elevationally over the containers. At least one driver is operable to move the conveyor working flights to transport received materials. The conveyors are selectively movable (a) toward one another to a substantially joined condition in which the conveyors operably combine to form a substantially single extent, and (b) away from one another to define discharge openings over selected ones of the containers.
