  • Patent number: 4109880
    Abstract: A spinning reel of the type having a bail arm and wherein an L-shaped kick lever rotating synchronously with the reel rotor engages a trip tab to thereby release the bail arm, further includes a braking surface immediately preceding the trip tab in the path of the projection. While the bail arm is cocked, slight rotation of the rotor due to eccentric weight distributions will be arrested when the braking surface frictionally engages the projection, thereby preventing premature and inadvertent release of the bail arm. The frictional engagement is relatively light, and may easily be overridden by turning the reel handle to thereby release the bail arm when desired.
