Abstract
A nutcracker for macadamia or other hard nuts (46) comprises an elongated slide bar (21) having an anvil jaw (43) attached to a working end thereof, a parallel elongated arm (35) having a mating jaw (33) attached to a working end thereof, and a hand lever (27) which has a pair of pivots (31B, 41) at one end thereof. The pivots on the hand lever are attached to force-applying ends of the arm (21) and bar (35), respectively, which are opposite to their working ends. The jaw on the bar has a portion (51) which extends around the bar so that the arm is held and will be forced to move only in a direction which is generally parallel to the bar. The anvil jaw on the bar is adjustable in position and is urged to the jaw on the arm by a spring (49). The parts are shaped and the pivots are positioned such that rotation of the hand lever from an open position where it makes a wide angle with the arm and bar to a position where it makes a narrow angle causes the arm to move parallel to the bar with tremendously multiplied force, which actually continually increases as the angle narrows. The device can be post mounted (FIG. 1), portable (FIG. 7), bowl mounted (FIG. 8), or surface mounted.
