ABSTRACT:
A method of and apparatus for crushing cans, such as aluminum cans, for facilitated further handling. The apparatus is adapted for crushing the can longitudinally to a partially crushed configuration defined by a collapsed cylindrical sidewall, a bottom wall extending substantially perpendicularly to the axis of the sidewall, and a top wall extending at an acute angle to the axis. The apparatus is further arranged to permit manipulating the partially crushed can to a different disposition wherein the partially crushed can is crushed to a final configuration defined by a further collapsed cylindrical sidewall thereof, a bottom wall extending substantially perpendicularly to the axis of the further collapsed sidewall, and a top wall reversely repositioned at a displacement angle to the original acute angle of the partially crushed can. In the illustrated embodiment, the displacement angle is at least equal to the acute angle so that the top wall is reversely repositioned from the original acute angle of the partially crushed can to at least a disposition perpendicular to the axis. In the illustrated embodiment, the apparatus includes a base and a lever pivotally interconnected for manipulation of a handle portion of the lever in effecting the above described crushing operation. The base is provided with a recess for effectively retaining the can during the partial crushing operation. The lever is provided with an annular recess for effective engagement with the top wall of the can in effecting the partial crushing operation.
