  • Rock crushing machine with dual cam shaft jaw driving mechanism
    Patent number: 4382560
    Abstract: 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.

  • Rock crushing machine with rotary eccentric jaw driving mechanism
    Patent number: 4248390
    Abstract: A rock crusher includes a rotary eccentric drive mechanism for imparting substantially linear motion to a movable jaw between a pair of fixed jaws. A driven cam shaft cooperates with a surrounding eccentric sleeve to impart this motion to the jaw. In one embodiment, the movable jaw is suspended between the fixed jaws by a pivot shaft and one such drive mechanism is employed. In another embodiment, a pair of such drive mechanisms operate together and cause the crushing motion.
