Abstract: In a can crusher, cans lying in a semicylindrical compaction chamber are crushed between a movable ram and a stationary anvil plate. The ram is driven by a ram rod extending from the ram, a ram rod crank arm pivoted to the ram rod and rotated by a power driven crankshaft. Crushed cans are ejected from between the ram and anvil plate after being crushed, and uncrushed cans are fed to a lengthwise position in the compaction chamber each time the ram moves back from the anvil plate. The uncrushed cans are fed, end to end, into the compaction chamber from a feed tube located above the chamber. The feed tube has a skewer receiving opening provided in it, and a skewer retaining sleeve extends out from the feed tube in surrounding relationship to the opening. The skewer crank arm is fixedly mounted on the crankshaft in fixed angular relationship with respect to the ram rod crank arm.
