ABSTRACT:
Accuracy and reproducibility of tuning with a low-cost mechanism in minimum space is achieved by a pair of flat, tapered-notch coupling members each being spring biased into firm engagement with the driving member at the opposite extremities thereof and with pins in guide slits of a driven member at the opposite extremities thereof, the slits preventing undesired displacement of the driving member at right angles to its intended motion and the combination of tapered slots and spring biasing preventing inaccurate displacement of the driving and driven members in the direction of intended motion thereof.
