Abstract
Abstract A powered length-setting device for use in structural beam cutoff sawing and the like, employing carriage-mounted resilient support and guidance wheels, direct acting internal expanding brake system, self-adjusting pendulum coupling of a resilient drive wheel, and closed-circuit television for observation of a scale on a fixed linear tape, permitting the use of a relatively primitive hot-rolled unmachined H-beam and an angle unit as a precision way by averaging-out irregularities; novel beam-contact assurance circuitry, shipping/field-assembly structure, and work ejector structure are also disclosed.
