A beverage can compactor including an elongate compaction chamber for receiving emptied beverage cans. A pair of crushing platens are positioned for reciprocating movement from the opposite respective ends of the compaction chamber toward each other and then return to their initial positions at the respective ends of the compaction chamber. The compactor provides increased mechanical advantage at the beginning and end of the crushing stroke when such increased force is needed. Faster movement of the crushing platens is provided at the midpoint of the crushing stroke.

A beverage can compactor comprising: an elongate, can-receiving, compaction chamber having a generally cylindrically curved bottom; a pair of substantially flat, disk-like platens adapted for reciprocation movement from the respective ends of said compaction chamber toward the central portion of said compaction chamber and then back to the respective ends of said compaction chamber, a first rotating crank positioned adjacent one end of said compaction chamber for rotation about an axis normal to the longitudinal axis of said compaction chamber; a first push rod connecting said first crank with one of the disk-like platens, so that as the first crank rotates, the push rod imparts reciprocating, translational motion to said one of the disk-like platens; second and third rotating cranks positioned for rotational movements in spaced, parallel planes along the mutually opposite sides of said compaction chamber; second and third push rods connecting the second and third cranks, respectively, to mutually opposite sides of the other disk-like platen, so that as the second and third cranks rotate, the push rods impart reciprocating, translational motion to said other disk-like platen; and means for rotating the second and third cranks in phase about their common axis and for rotating the first crank about said common axis but 180°out of phase with respect to the second and third cranks, whereby the pair of platens move from the opposite ends, respectively, of the compaction chamber towards each other during one-half cycle in the rotation of the first, second, and third cranks and then move away from each other back to their respective ends of the compaction chamber as the first, second, and third cranks complete the second half-cycle of the rotation.
