  • Automatic adjusting nutcracker
    Patent number: 4466343
    Abstract: A nutcracker includes a base (12), a stationary jaw (16), a movable jaw (21) and an adjustable post (20). A driving cylinder (36) is urged along the longitudinal axis of the post (20) by a lever (26) connected through a connecting link (30). A spring (42) allows the post (20) to float until a canting pin (46) contacts one end of a ring (22) disposed around the post (20). When the ring (22) cants to contact the post (20), the force applied to the driving cylinder (36) is translated directly to the post (20) to crack a nut disposed between the stationary jaw (16) and the movable jaw (21).
