  • Patent number: 4986717
    Abstract: An apparatus for evacuating viscous or compacted contents from a drum having a cylindrical wall of steel, fiberboard, or other material suitable for such contents and opposite ends, each of which is open except for a movable plunger at one such end serving as the lower end of the drum when the drum is standing on a floor in readiness for the apparatus. The apparatus comprises a support adapted to attach to the fork of a forklift, and a cradle and a pair of hinged closures for securing the drum removably to the cradle. The cradle and hinged closures keyingly engage the drum and are mounted to move the drum between upright and tilted portions. A disc-shaped ramming element fits into and through the cylindrical wall of the drum in the tilted position and forces the contents out of the other end of the drum. A suitable drum is a fiberboard drum with full open ends and with a movable plunger.
