  • Portable rescue tool
    Patent number: 10307621
    Abstract: A portable rescue tool that is powered by an electric motor. The electric motor has a drive output shaft that transfers rotational power to an angle rotary gearbox. The angle rotary gearbox has an output shaft that is oriented about 90 degrees from the rotational axis of the motor output shaft and is geared so as to increase the torque and reduce the speed of the rotational power. The angle rotary gearbox provides a reduced speed, high torque output at an output shaft that is delivered by a single chain drive to a main rotary actuator where two actuator arms are controlled to move away from each other and toward each other in the operation of the rescue tool. The portable rescue tool is designed to be of a low weight and enhanced cooling properties as present rescue tools.

    Abstract: An apparatus and method for moving a wire along its own axis against a high resistance to its motion causing a substantial uniaxial compression stress in the wire without allowing it to buckle. The apparatus consists of a wire gripping and moving drive wheel and guide rollers for transporting the moving wire away from the drive wheel. Wire is pressed into a peripheral groove in a relatively large diameter, rotating drive wheel by a set of small diameter rollers arranged along part of the periphery causing the wire to be gripped by the groove.
