Abstract
A safety cover assembly for use with an associated storage drum. The assembly includes a drum insert with a collar having a two-part cover assembly disposed atop the collar. The moveable part of the cover assembly is actuated by one portion of a crank mechanism, the other portion of which includes a pair of ends secured to a treadle and riser assembly. In use, pushing down on the treadle lowers the one portion of the crank mechanism, and raising the other portion and the associated cover. The treadle and riser assembly is open at the rear to facilitate removal and replacement of the drum. The moveable cover part may be secured to the crank by a fusible link for fire protection.
