Abstract: A nutcracker includes a frame having a jaw member mounted thereon and connected to a threaded support portion for movement relative to said frame to adjust for the size of nuts being cracked. A second jaw member is mounted juxtaposed to the first jaw member and is pivotally supported on said frame for oscillating movement by a rotating cam. A nut support member has a trough portion which is disposed below and between the jaw members in their minimum spaced position to crush a nut for supporting the nut for engagement by the jaw members and for movement to discharge a nut into a container disposed below the jaw members after the shell cracking or crushing cycle is completed.

Abstract: A nutcracking apparatus comprising a motor driven rotary roller type cracker member with longitudinal serrations or teeth which engages a nut and forcibly cracks the shell between the roller member and a stationary cracking member comprising a plurality of spaced apart cracking plates having a series of serrations or teeth formed thereon along a curved path. The stationary cracking member is mounted on a support member which is slidable on a bearing member within the apparatus housing and is adjustably positioned by an actuating screw. The adjustable support member includes a gauging jaw mounted thereon which is cooperable with a second gauging jaw mounted on the apparatus housing for gauging the overall dimension of a shell-enclosed nut.
