A rock crusher includes a dual cam shaft drive mechanism for imparting substantially linear motion to a movable jaw between a pair of fixed jaws. A driven cam shaft coupled to the movable jaw cooperates with another cam shaft also coupled to the jaw to impart this motion to the jaw. In one embodiment, the maximum eccentricity of the driven cam shaft is less than the maximum eccentricity of the other cam shaft so that the other cam shaft oscillates and imparts the desired motion to the movable jaw. In another embodiment, the cam shafts have the same maximum eccentricity and are synchronized to move together, such as by gears, during crushing.
