Abstract

Abstract The truck type vehicle constructed to receive, transport and dump municipal waste, garbage, industrial debris and so on, and this using for storage a maximum of space within the truck body, notwithstanding the inclusion of apparatus for compacting or packing material preparatory to the taking on of subsequent loads. The subject truck includes a packer panel driven fore and aft within the truck body by a threaded shaft. The shaft is journaled forwardly and also at a rear door rearwardly of and a part of the truck body. The packer panel supports its driven threaded shaft, when the rear door is open, by the packer panel being proximate its rear-most extremity. Means are provided for keeping the threaded shaft of the truck body clean from debris and bearing surfaces free of dirt or other foreign matter. Means are provided for powering the packer panel, through revolvement of the threaded shaft, either by the power take-off of the truck or by a gear reduced electric motor drive. Safety means are provided such that the packer panel will not exceed its predetermined limits of travel and, also, can be stopped at any time and at any point intermediate of such extremities. Means are provided for keeping clean wear surfaces and caster and track surfaces, as applies to the caster supported packer panel.
