Abstract
Refuse compaction apparatus includes a hopper with two opposite side walls and with two shafts, one in each side wall. A torque tube is disposed on the first shaft for rotation and is independent of the second shaft and is constructed to withstand high forces. A packer panel is constructed to transmit torque and to withstand twisting moments. The packer panel may be provided with an elliptical configuration in cross-section with the major axis of the ellipse extending toward the torque tube. Means couple the packer panel to the torque tube in a rigidified relationship to rotate the packer panel with the torque tube. Means also mount the packer panel on the second shaft in a stiffening relationship. A second packer panel may be disposed in the hopper for movement with the first packer panel and for independent movement relative to the first packer panel. Means are operatively coupled to the first and second packer panels for providing for a movement of the second packer panel with the first packer panel and for providing a movement of the second packer panel independently of the movement of the first packer panel.
