ABSTRACT:
An apparatus is disclosed for a two-stage crushing of empty cans along their longitudinal axes to collapse them to minimum bulk. The apparatus has a stanchion fixed to a base and long and short lever arms pivotally mounted on the stanchion. A pivotal linkage interconnects the long lever arm with the short lever arm. First and second crush heads are pivotally mounted between the base and the long and short lever arms with a pantograph type linkage to control the attitude of the crush heads.
In the first stage of crushing, the can is placed between the first of the crush heads and the base, and the long lever arm is moved toward the base to partially crush the can axially. In the second stage, the partially collapsed can is placed between the base and the second crush head. The long lever arm is moved toward the base thereby moving the short lever arm toward the base and the can is thereby completely axially crushed.
