Abstract
Abstract A non-snagging fishing device for use as a sinker for a fishing line characterized by an elongated tubular body having a flotation portion adjacent one end and the weight concentrated adjacent the other end so that it assumes a substantially upright position in the water. The device is preferably provided with a chamber adjacent the weighted end to receive additional weight to increase the weight of the device. In one embodiment, the body portion is provided by a pair of plastic tubular sections interconnected by a coupling device to enable breakdown for storage and transportation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
190 words
A non-snagging fishing device for use as a sinker with a fishing line comprising an elongated and flexible body portion having a thin cross section and a smooth outer surface, said body portion being formed by a tube having both ends closed with one end being closed by a weight mounted in said end and the other end being closed by means for attaching the device to a fishing line, said body portion having a plug disposed in said tube in spaced relation to said means for attaching to separate the interior of the body portion into a sealed air chamber forming a buoyant portion adjacent the means for attaching and a second chamber adjacent to the weight for receiving additional weight elements so that the weight of the device is concentrated adjacent said one end to cause said device to assume a position in a body of water with said one end lower than the other end so that even if the device sinks to the bottom of the body of water, it can be retrieved without snagging on obstructions on the bottom and in the path of retrieval.
Claim 2
Dependent Claim
190 words
A non-snagging fishing device for use as a sinker with a fishing line comprising an elongated and flexible body portion having a thin cross section and a smooth outer surface, said body portion being formed by a tube having both ends closed with one end being closed by a weight mounted in said end and the other end being closed by means for attaching the device to a fishing line, said body portion having a plug disposed in said tube in spaced relation to said means for attaching to separate the interior of the body portion into a sealed air chamber forming a buoyant portion adjacent the means for attaching and a second chamber adjacent to the weight for receiving additional weight elements so that the weight of the device is concentrated adjacent said one end to cause said device to assume a position in a body of water with said one end lower than the other end so that even if the device sinks to the bottom of the body of water, it can be retrieved without snagging on obstructions on the bottom and in the path of retrieval.
Claim 3
Dependent Claim
40 words
A non-snagging fishing device according to claim 1, wherein the weight mounted in the one end of the tube is detachably mounted therein, to enable changes in the size of the weight and to enable access to said second chamber.
Claim 4
Dependent Claim
24 words
A non-snagging fishing device according to claim 1, wherein said means for attaching comprises a plug sealed in said other end of the tube.
Claim 5
Dependent Claim
65 words
A non-snagging fishing device according to claim 1, wherein said tube forming said body portion comprises two sections with the first section being closed and sealed by said plug and by said means for attaching to provide the sealed air chamber, and the second section being connected to the first section by coupling means provided on said plug and an end of the second section.
Claim 6
Dependent Claim
49 words
A non-snagging fishing device according to claim 4, wherein said coupling means enables access to the interior of the second tube section to enable changing of the weight contained in said second chamber to adjust the total weight of the device to vary the sinking and floating characteristic thereof.
