Abstract

A refuse compaction apparatus including a hopper and a panel rotatably positioned for movement through the hopper. The panel has a body with a generally elliptical cross-sectional configuration and a high torque-transmitting capability. Drive means are connected to only one end of the panel with the drive means imparting a rotational force to the panel at said one end, which force is transmitted throughout the panel by the generally elliptically-shaped body. A refuse compaction apparatus having a container for storing refuse under pressure and means for pressurizing refuse within the container. The container includes a first rigid frame positioned at one end and a second rigid frame positioned at the other end of the container. A plurality of longitudinal members interconnect the first and second frames and a plurality of flexible metal sheet members enclose the container with the sheet members being supported by the first and second frames and by the longitudinal members. The flexible sheet members are bowed outwardly from their points of support, such that the sheet members are placed in tension in resisting pressure within the storage container.

Dependent claims

In a refuse compaction apparatus for support on a truck frame, the refuse compaction apparatus having a container for storing refuse under pressure and means for pressurizing refuse within said container, the improvement comprising:

a first rigid frame positioned at one end of said container,
a second rigid frame positioned at the other end of said container,
a plurality of longitudinal rigid members connecting said first and second frames without any additional support between the first and second frames,
a plurality of members formed from a thin sheet material and defining the container and supported at their peripheries by said first and second frames and said longitudinal rigid members,
said flexible sheet members being bowed outwardly in tension at their peripheries,
first means coupled to the first frame and disposed below the first frame for providing a support between the container and the truck frame,
second means coupled to the second frame and disposed below the second frame for providing a support between the container and the truck frame,
means disposed below the first support means and supported by the first support means at a position below the first frame for providing for a coupling of the container to the truck frame, and
means disposed below the second support means and supported by the second support means at a position below the second frame for providing for a coupling of the container to the truck frame.

In combination for storing refuse and for attachment to a truck frame,

first, second, third and fourth sheet members having flexible characteristics and disposed in an outwardly bowed relationship and having a high strength in tension as compared to their strengths in compression,
the first, second, third and fourth sheet members being disposed to define a storage body with the first and second sheet member defining side panels of the storage body and the third and fourth sheets defining the top and bottom walls of the storage body,
a plurality of stiffening means each disposed at one of the corners of the storage body defined by parts of the first, second, third and fourth sheet members,
a first rigid frame extending around the storage body at one end of the storage body,
a second rigid frame extending around the storage body at the other end of the storage body,
means providing rigidity to the first rigid frame,
means providing rigidity to the second rigid frame,
means disposed below only the first frame for providing a support for the storage body on the truck frame at the first end of the storage body, and
means disposed below only the second frame for providing a support for the storage body on the truck frame at the second end of the storage body.
