  • Compactor door and interlock
    Patent number: 5044271
    Abstract: An improved manually fed waste baling compactor has a single interlock switch which controls movement of a vertically oriented ram and platen such that the ram cannot move unless both a chamber door and a guard door of the mechanism are properly positioned. A magnetic interlock prevents opening the guard door manually until after the compression and retraction stroke of the ram.
