Abstract
Abstract A refuse-packing system including a stationary packer with a ram reciprocable toward and away from a side outlet opening to pack refuse into an enclosed container having a loading opening aligned with the opening. The packer has a vertically reciprocating, fluid-actuated door-operating mechanism engaged with a guillotine-type door on the container as an incident to the positioning of the container, and latched to the door as an incident to the initial raising of the door, and also has a guide and an automatic latch for aligning and holding the container relative to the packer. For closing of the door, the ram is positioned at the loading opening and the door slides along the face of the ram to the closed position.
