ABSTRACT:
A trash compactor using a dolly as a receptacle for the trash to be compacted. The dolly is normally spring supported ready for movement into and out of the compactor, but when in the compactor and subjected to compacting pressure, the dolly is pressed downwardly, upon the beams of the main compactor frame which then takes the full compacting pressures.
A novel construction of the dolly and compactor floor of the main frame makes such transfer of load possible. The compacting pressure is developed by four hydraulic cylinders, all of which are mounted on a common plate. The rod ends of the two center cylinders are connected to the top member of the main frame and the cylinder ends are connected to the common plate. The rod ends of the remaining two cylinders are connected to the main compacting plate with the cylinder ends mounted on the common plate. With the four cylinders mounted in this manner, twice the movement of the compacting ram is obtained. Safety devices include a deflection switch actuated when a deflection exceeding a given amount takes place within the frame assembly. Such deflection may be caused by solid materials, such as logs, bricks, etc., inadvertently placed in the material to be compacted. Under normal conditions, the cylinders will reverse and the unit will automatically stop once the cylinders reach the limit of their upward stroke. A magnetic switch and latch operated switches serves to prevent operation of the ram unless the trash loading door and dolly are in the closed and latched position.
