  • Crusher for metal cans
    Patent number: 5584239
    Abstract: A can crusher has a handle that pivots about a first axis. A first plate is fixed to the handle. A bottom plate is movable along the handle. A rod rotates about a second axis in response to pivoting of the handle to move the second plate, guided by a carrier, toward the first plate and thereby crush a can between the plates. In a modified embodiment, the second plate tilts relative to the first plate in two steps as the bottom plate approaches the top plate.
