  • Spinning reel with finger controlled drag
    Patent number: 4470554
    Abstract: A spring biased lever 11 controls the axial compression force exerted on a drag force generating mechanism 18 via cooperating pairs of pivotally mounted operating and pressing levers 12, 16. The minimum drag may be set to a desired value by eccentric cams 24a rotated by a control knob 28 and which engage and act as limit stops for the pressing levers 16. A single finger of the rod gripping hand operates the drag lever, which may continuously increase and decrease the drag force above the preset level. The line spool 5 may be idled as there is no operative coupling between the rotor drive and the drag force generating or control mechanism.
