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.
