  • Patent number: 4827840
    Abstract: A can crusher comprising a vertical hopper to receive empty cans laid horizontally in a vertical stack one above the other, with the bottton can in the stack being positioned in end-to-end registration with a plunger head which reciprocates horizontally between a withdrawn position out of contact with the bottom can and an extended position to crush and compress the bottom can. When the plunger is withdrawn, the crushed can drops through a discharge opening just large enough for the compressed can to drop through but small enough to prevent an uncrushed can from falling through. The crushed can drops into a container placed below the discharge opening, and the next can in the vertical stack falls in place in registration with the plunger for crushing. The plunger head is moved between its withdrawn and extended positions by a drive rod pivotally connected to an intermediate portion of a lever which in turn is pivotally connected at one end to a pivot pin mounted in front of the vertical hopper.
