  • Vise with jaw control
    Patent number: 6595508
    Abstract: A vise (10) having a control aperture (74) at an accessible end (54) of a screw rod (50) and extending along the rotational axis (52) thereof. The aperture (74) is sized and shaped to accept the anvil (72) of a drive mechanism (70) so that upon rotation of the anvil (72) along its torque axis (80), screw rod (50) rotates about its rotational axis (52). At least one of a pair of jaws (18, 20) is operatively associated with screw rod (50) to thereby vary the spacing (34) therebetween as screw rod (50) rotates under control of the anvil (72).
