  • Patent number: 4266900
    Abstract: A material handling apparatus is described, for example, for delivering bags of garbage to an incinerator. The apparatus includes a plurality of material-receiving compartments, each having a first end at which material can be loaded into the compartment, and a second end from which material can be discharged. Each compartment includes a belt conveyor which forms a bottom wall of the compartment and which is operable to move material longitudinally of the compartment in a direction towards said second end. Side walls of the compartment extend upwardly adjacent respective the opposite sides of the conveyor for laterally constraining material in the compartment. The compartment also includes closure means normally preventing discharge of material from said second end of the compartment, said closure means being adapted to be opened at appropriate times to allow material to be discharged from said compartment by operating the belt conveyor.
