Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A sinker for holding down a running fishing line in bodies of water in which there is a current, said sinker comprising: an elongated relatively flat body of heavy material having a length which is at least 4 times the thickness thereof and a width which is at least two and one-half times the thickness thereof; said elongated body being defined by oppositely disposed generally planar flank areas and continuous side edges and including a centered longitudinal bore therethrough through which the running fishing line passes, wherein when the sinker rests on a bottom of a body of water, eddy currents created by the current flowing over the sinker in cooperation with slippage of the running line stabilizes the sinker so that the sinker is not moved by slight forces on the running line.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
16 words
The sinker of claim 1 in which said flank areas are substantially parallel to each other.
Claim 4
Dependent Claim
11 words
The sinker of claim 2 in which said body is oval.
Claim 5
Dependent Claim
19 words
The sinker of claim 1 in which said flank areas converge toward a first longitudinal end of said body.
Claim 6
Dependent Claim
23 words
The sinker of claim 4 in which the lateral edges of said body progressively converge toward said first longitudinal end of said body.
Claim 7
Dependent Claim
20 words
The sinker of claim 1 in which said line engaging means includes a second bore extended transversely of said body.
