Claim 1
Independent Claim
456 words
A two-piece swiveling sinker for fishing tackle comprising a lead weight and a line attachment member, said lead weight having sufficient weight to sink a fishing line and hook and said line attachment member having a surface to allow said lead weight to rotate thereon, said lead weight consisting of a single member, said lead weight having a hole therein of a first diameter for receiving a line attachment member, said lead weight further having a surface for rotatably engaging a line attachment member, said lead weight and said line attachment member coacting so that when a fishing line and hook are attached to said line attachment member, the fishing line and hook will sink when placed in water, said line attachment member consisting of a single piece pliable member formed from a polymer plastic material, said pliable member having a looped portion at one end having at least a portion of the loop dimension larger than the hole in said lead weight to thereby prevent said line attachment member from passing completely through the hole in said lead weight, a shank portion in the middle of a diameter less than the diameter of the hole in the lead weight so as to be suitable to pass through the hole in said lead weight and permit said lead weight to rotate about said entire line attachment member, said pliable member having an enlarged portion at the other end, said enlarged portion having a diameter greater than the diameter of the hole in said weight so as to be operable to prevent withdrawal of said shank portion from said hole, said enlarged portion comprising a heat formed section of said shank portion, said enlarged portion further having a surface for forming rotatable engagement with said surface on said leaD weight so that said lead weight can rotate freely on said surface on said enlarged portion; said looped portion formed of a relatively rigid straight section on one side and a substantially semicircular section on the other side, said two sections being joined at one end and open and contiguous at the other end so as to allow sufficient relative flexing of said two sections to permit the entry of a connecting means therebetween into said looped portion; an additional finger portion extending at an acute angle from said straight section toward the inside of said substantially semicircular section portion to help keep said connecting means between said two sections; said contiguous end of said semicircular portion located on the outside of said finger portion; and said semicircular portion having a radiused corner with an excess of material at the junction of said semicircular portion to said straight sections to thereby provide additional strength to said semicircular portion.

A two-piece swiveling sinker for fishing tackle comprising a lead weight and a line attachment member, said lead weight having sufficient weight to sink a fishing line and hook and said line attachment member having a surface to allow said lead weight to rotate thereon, said lead weight consisting of a single member, said lead weight having a hole therein of a first diameter for receiving a line attachment member, said lead weight further having a surface for rotatably engaging a line attachment member, said lead weight and said line attachment member coacting so that when a fishing line and hook are attached to said line attachment member, the fishing line and hook will sink when placed in water, said line attachment member consisting of a single piece pliable member formed from a polymer plastic material, said pliable member having a looped portion at one end having at least a portion of the loop dimension larger than the hole in said lead weight to thereby prevent said line attachment member from passing completely through the hole in said lead weight, a shank portion in the middle of a diameter less than the diameter of the hole in the lead weight so as to be suitable to pass through the hole in said lead weight and permit said lead weight to rotate about said entire line attachment member, said pliable member having an enlarged portion at the other end, said enlarged portion having a diameter greater than the diameter of the hole in said weight so as to be operable to prevent withdrawal of said shank portion from said hole, said enlarged portion comprising a heat formed section of said shank portion, said enlarged portion further having a surface for forming rotatable engagement with said surface on said leaD weight so that said lead weight can rotate freely on said surface on said enlarged portion; said looped portion formed of a relatively rigid straight section on one side and a substantially semicircular section on the other side, said two sections being joined at one end and open and contiguous at the other end so as to allow sufficient relative flexing of said two sections to permit the entry of a connecting means therebetween into said looped portion; an additional finger portion extending at an acute angle from said straight section toward the inside of said substantially semicircular section portion to help keep said connecting means between said two sections; said contiguous end of said semicircular portion located on the outside of said finger portion; and said semicircular portion having a radiused corner with an excess of material at the junction of said semicircular portion to said straight sections to thereby provide additional strength to said semicircular portion.
Claim 3
