The tray frame presents a curvature along its entire circumference.

Abstract: A compaction mechanism uses cables to move a compaction plate within a compaction chamber of a garbage truck. Cable guide pulleys are positioned adjacent a first end and a second end of the compaction chamber. Each cable has a first end and a second end, both of which are secured to the compaction plate. A winch-like drive assembly is used to concurrently move the cables to pull the compaction plate. This compaction mechanism is better able to withstand uneven resistance on the compaction plate without twisting.

Abstract: The present invention relates generally to a frameless high pressure press. The high pressure press includes first and second opposed plates that are at least partially surrounded by a wrapping structure. A lift device is positioned on one of the first and second plates at a location offset from the wrapping structure. The press also includes a linkage structure that transfers force generated by the lift device to the wrapping structure such that the wrapping structure forces the plates together. The linkage structure includes a tensioning member connected to the wrapping structure and generally transversely aligned with respect to the plates. The linkage structure also includes a cross member that extends between the lift device and the tensioning mechanism. The length of the tensioning member can be adjusted to control the level of force multiplication generated by the press.

Abstract: A press has a framework (1) which supports a pressure plate (3). The pressure plate is attached to a fluid operated ram assembly (4) by means of gimbals (20) so that the pressure plate (3) may adopt different angular attitudes relative to the load being compressed. In order to prevent the ram assembly (4) being subjected to stress the ram assembly (4) is mounted on the framework (1) by means of gimbals (18). The freedom of movement of the pressure plate (3) laterally is restrained by opposed pins (26) which engage loosely in slots (27) on the frame and stops (28) on the opposed pins. The press may be used to compress a palletized load, such as cardboard box blanks, prior to banding.

Abstract: An improved can crusher has two movable jaws, a first jaw and a second jaw, both movably mounted in a support housing. The jaws are initially spaced apart one from the other a distance sufficient to allow a can to be inserted between them. A member capable of generating a mechanical force is mounted on the housing and is directly connected by a connecting member to the second of the movable jaws by a force transferring member and is indirectly connected by the same connecting member to the first jaw by a force modifying member. The force modifying member modifies the mechanical force so generated to achieve a mechanical advantage. When the member capable of generating the mechanical force is activated this force is first transferred to the first jaw, and because of the mechanical advantage achieved, the first jaw is able to initially overcome the structural resistance of the can and crimp it.

Abstract: A hold-down beam is provided on a rapid acceleration conveyor to hold articles, such as an unstable stack of newspapers, tightly against the conveyor for providing frictional engagement between the stack and the conveyor and move the upper part of the stack with the conveyor so that the stack will not topple. The hold-down bar is unpowered, that is, it is mounted for reciprocation in low-friction bearings so that its own frictional engagement with the top of the stack carries it along with the top of the stack until the stack is brought up to the desired velocity. A unique cable system for lowering both ends of a hold-down bar synchronously through an infinite number of positions and does not interfere with operation of a strapping machine.
