Abstract
There is disclosed a device for adjusting tension of an elongated filament having one end thereof coupled to a supporting structure, the device having a lever arm adapted to be pivotally attached to the supporting structure, a tuning peg having ratchet notches therein and being rotatably attached to the lever arm and being adapted to engage and adjustably wind the elongated filament therearound, a spring stop attached to the lever arm for engaging the ratchet notches of the tuning peg and an adjusting screw attached to the supporting structure and engaging the lever arm for pivotally positioning the lever arm with respect to the supporting structure whereby the tension of the elongated filament is coarsely adjusted by rotating the tuning peg and finely adjusted by pivoting the lever arm.
