ABSTRACT:
The trash compactor of the present invention utilizes a three piece toggle linkage mechanism for moving the compactor blade from its inoperative to its operative position. The toggle linkage includes a frame link hinged to the frame of the compactor, a primary link hinged to the frame link, and a blade link pivotally connected to the primary link and also pivotally connected to the compactor blade. Hydraulic cylinders are operatively connected to the linkage mechanism for causing movement of the compactor blade from its initial position to its compacting position. Another feature of the trash compactor, includes a counterbalance mechanism for the door to the compactor, the counterbalance mechanism being adapted to neutralize the weight of the door throughout the swinging movement of the door from its open to its closed position. A safety interlock is engaged by a cam plate on the door so that the hydraulic system is inoperative whenever the door is open.
