ABSTRACT:
A nutcracker (10) is disclosed which is characterized by an automatic adjustment to differing-sized nuts during the cracking motion. Nutcracker (10) includes a base (11), an upright support (12) carried by base (11) and a slide bar (16) mounted for limited sliding movement on upright support (12). A nut-cracking head (40) is pivotally mounted for sliding movement on slide bar (16) and a handle (30) is carried by base (11) to move the slide bar (16) back and forth along its direction of travel. A rack (22) is mounted on the slide bar (16) and a tooth (46) is carried by head (40) and positioned to pivot towards and engage rack (22) at a point thereon dependent on the size of the nut as the handle moves head (40) into engagement with the nut to arrest the free movement of the head and cause the head (40) to move in unison with handle (30) as handle (30) continues to move into nut-cracking position. Accordingly, the nut itself provides the means for adjusting head (40) to the proper position to crack successive, differing-sized nuts.
