Abstract
A body of material having a high specific gravity to enable use as a weight for fishing with the body of material having an external casing or skin covering that conforms to the exterior surface of the body of material to inhibit fracturing or prevent loss of the sinker parts should the body of material fracture. In addition, the covering can incorporate a visual indicator to assist a user in identifying the type of sinker as well as providing other information to the user.
Claims33
A fishing sinker comprising:
- a body of frangible material, said body of frangible material having an exterior surface and a specific gravity of at least 7.0;
- a member connected to said body of material for securing the body of material to a fishing line;
- and
- a skin extending substantially around said exterior surface, said skin compressively engaging said body of material to inhibit fracture of the body of material.
The method of making a bismuth fishing sinker:
- comprising the steps of:
- pouring a bismuth in a molten state into a fishing sinker mold;
- allowing the bismuth to solidify in the fishing sinker mold to form a bismuth fishing sinker;
- removing the solidified bismuth fishing sinker from the fishing sinker mold;
- placing a shrink wrap film material around an exterior surface of the solidified bismuth;
- and
- heating the shrink wrap film material to bring the shrink wrap film into compressive confinement of the solidified bismuth to thereby inhibit the fracturing of the bismuth fishing sinker if the bismuth fishing sinker is impacted by an external force.
The method of making a fishing sinker comprising the steps of:
- pouring a frangible metal having a specific gravity of at least 7.0 into a fishing sinker mold;
- allowing the frangible metal to solidify in the fishing sinker mold to form a fishing sinker;
- removing the solidified fishing sinker from the fishing sinker mold;
- and
- covering the exterior surface of the solidified fishing sinker with a layer of skin to thereby provide fracture resistance to the frangible material.
A three-part fishing sinker comprising:
- a line attachment member;
- a body of frangible material, said body of frangible material having a specific gravity sufficiently high to enable use as a fishing sinker;
- and
- a skin compressively conforming to substantially all of an exterior surface of the body of frangible material so as to confine and retain said frangible material in the event the frangible material should fracture during use.
A fishing sinker comprising:
- a body of material having a specific gravity sufficiently high to enable use as a fishing sinker said body of material having an internal line attachment member for securing a fishing line thereto;
- and
- a casing carried on an exterior surface of the body of material, said casing confining said body material therein while allowing a user free access to the line attachment member in the body of material.
