ABSTRACT:
Apparatus for sensing the tension in a cable and for maintaining the tension between a minimum tension and a maximum tension value comprises a rocker carrying a pulley about which the cable is passed, the rocker being pivotally supported for rotation between first and second rotational positions and being biased toward the first rotational position. Upon tension being applied to the cable, the rocker pivots away from the first position by an amount proporational to the cable tension. Spring biased plungers and associated switches sense the rocker being respectively at the first and second rotational positions and control the tension applied to the cable so as to maintain the tension between the selected minimum and maximum values.
