Abstract
A tension measuring device for accurately measuring the tension applied to a fine, metallic wire, or the like, being uncoiled from a spool of wire, or the like. The tensioning device includes a pulley around which the wire is looped. The pulley is rotatably mounted at the end of an arm which itself is mounted on an axle for rotation under the influence of a first torsion spring which biases the arm against the tension forces exerted against the uncoiling wire and a second torsion spring which biases the arm against rotation caused by the weight of the arm and pulley. A knob is provided to twist the first torsion spring to increase the biasing force on the arm and pulley which counteracts the uncoiling tension on the wire. A pointer is associated with the knob and it moves across a scale indicating the amount of force applied to the first torsion spring. Another pointer is mounted on the arm and it moves across a second scale indicating movement of the arm above and below a zero point. A mechanism is provided for accurately zeroing the arm pointer by adjusting the tension force applied by the second torsion spring to overcome the weight of the arm and its pulley.
