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).

Abstract: A mobile fire safety training facility which simulates a residential structure and has reduced scale rooms and exterior for appeal to children. A two level structure mounted on a conventional flat bed trailer includes conventional house windows and doors for instruction on escape methods, a non-toxic smoke generator, operating smoke alarms and a functioning telephone system for instruction on emergency telephone use. The reduced overall height of the structure and a truss roof structure permit highway transportation, and an on-board control room with full view of the entire interior assures the safety of the children using the facility.
