  • Patent number: 5832655
    Abstract: An improved sinker and hook locking apparatus for locking a sinker and hook together is disclosed. The hook has an eyelet for connecting the hook to a fishing line. The locking apparatus comprises an elongated sinker body with a longitudinal bore for slidably receiving the fishing line therethrough. A spring having a coiled portion adapted to be received in the sinker body, and an opposite J-shaped connector is adapted for engagement with the hook eyelet. The coiled portion being of a size and shape such that when received within the sinker body, a frictional fit is achieved therebetween.

  • Patent number: 5537775
    Abstract: An improved weighted jig is disclosed having a fishhook with an elongated shank having first and second ends; a U-shaped hook secured to the first shank end. A shoulder is attached to the shank second end and extends generally perpendicularly from the shank. The shoulder is formed by a member having two ends and connected at one of the ends to the shank second end and folded back on itself. An eyelet for connection of a fishing line, is formed at the point of folding of the member back upon itself. A locking device is secured to the shoulder, the locking device being movable between a locking position and a release position.

  • Patent number: 5535540
    Abstract: An improved weighted jigging system for use with a malleable lure body and a fishhook has a sinker body with front and rear portions and a bore for slidably receiving a fishing line. A hook locking device is adapted to be received and releasably secured within the bore, which locking device comprises a fishhook connection member for releasably engaging the fishhook eyelet such that the fishhook is releasably retained to the sinker body. The fishing line is adapted to be fastened to the fishhook eyelet such that upon engagement of the fishhook eyelet by the fishhook connection member of the fishhook locking device, a substantially unitary fishhook sinker apparatus is formed.

  • Patent number: 5435095
    Abstract: A sinker for attachment to a fishing line includes a generally spherical, generally rigid solid body having a radius and first and second generally V-shaped radial slots in the solid body, each of the slots having opposite end portions. The radial slots are arranged generally opposite one another on the body and each radial slot further includes a base having a transfer extent sufficient to accept at least two runs of fishing line side-by-side. A bore hole having opposite ends extends through the body and connects the first and second radial slots. Finally, the ends of the bore hole and the end portions of the radial slots are contoured such that fishing line running through the bore hole and radial slots will not become frayed or kinked resulting in a loss of line tensile strength.
