Abstract
Abstract A container with reinforced side walls includes an internal partitive wall forming two longitudinal compartments each associated with a transfer member including a ram to compact refuse and other waste materials into the container compartment. Push-out assemblies are supported at the rear of each compartment to eject compacted material therein. A hinged door on the partitive wall is latched by a load-bearing assembly to a side wall while forming an entry port below the door. A container end door is closed against the upper portion of the container. An opening in the lower part of the door communicates with two entry portal openings for delivery of material into the compartments. Separate security chutes communicate with separate charging boxes formed in the compactor.

A material-handling apparatus including a container having upstanding side walls, a bottom wall and a roof wall adjoined along the side edges thereof, said container further having a front end wall means adjoined with one end of said walls and rear door means at the other ends of said walls, hinge means to support said rear door means on one of said walls, an internal partitive wall supported by said floor wall and roof wall between said side walls for subdividing the space enclosed by said walls into two longitudinal storage compartments, each at an opposite lateral side of the internal partitive wall, latch means to retain said rear door means in closed position against part of some of said walls to define two portal openings each communicating with one of said two storage compartments for separate passage of material into each of the compartments, a compartment door to form an enclosure for one of said two compartments, hinge means for swinging said compartment door between said partitive wall and one of said side walls, a pivot shaft supported by one of said side walls, a pivotal latch plate having an arcuate body section with a curved projecting end portion to move along a radial path about said pivot shaft, spaced-apart latch bars supported by said compartment door to receive the curved projecting end of a latch plate therebetween for preventing swinging of the compartment door about said hinge means, said curved projecting end portion of the pivot latch plate being movable into a locked position by partly wrapping around one of said latch bars to captively engage between said latch bars for load-bearing contact to effectively increase the rigidity of said partitive wall and said side walls, transfer means including two rams each communicating with one portal opening to separately advance material into said compartments under a compacting force, and means to support said transfer means for detachable connection with said container.

Claim 3
Dependent Claim
245 words
A material-handling apparatus including a container having upstanding side walls, a bottom wall and a roof wall adjoined together along the side edges thereof, said container further having a front end wall means adjoining with one end of said walls and rear door means supported by hinges at the other ends of said walls to form a partial end closure for the space between said side walls, an internal partitive walls extending between said floor wall and roof wall for subdividing the space enclosed by said walls into two longitudinal storage compartments, each at an opposite lateral side of the internal partitive wall, latch means to retain said rear door means in closed position against part of some of said walls to define two portal openings each communicating with one of said two storage compartments for separate passage of material into each of the compartments, and means for resisting the separating force by compressed material on the vertical sides of one of said compartments, said apparatus further including ground supported transfer means separate from said container, said transfer means including two rams each communicating with one portal opening to separately advance material into said compartments under a compacting force, two charging chambers each having a material-receiving opening traversed by one of said rams for displacing material into a compartment of said container, means to support said transfer means for detachable connection with said container, and means for releasably clamping said transfer means to said container.
