Abstract
A fishing tool to snag and to retrieve cables from wells. The tool includes an elongated body which has two ends, a substantial length, and peripheral boundary of lesser lateral dimensions than a well down which the tool is to be sent with the first of its ends pointed down. A snag member comprises a shank and a snag end on the shank. The shank is mounted to the body so that the snag end faces toward the second of said ends and so that the snag end is movable toward and away from the peripheral boundary. Bias means biases the shank to move the snag end toward the peripheral boundary, and a detent is interposed between the snag member and the body releasably to hold the snag member with its snag end away from the boundary in opposition to the bias force, where it can be released upon contact with an object.

A fishing tool to snag and retrieve cables from wells, comprising:
- an elongated body having two ends, a substantial length, and a peripheral boundary of lesser lateral dimensions than a well down which the tool is to be sent with a first of its ends pointed down;
- a snag member comprising a shank and a snag end on said shank, said shank being mounted to said body so that said snag end faces toward the second of said ends and so that said snag end is movable toward and away from said peripheral boundary;
- bias means biasing said shank to move said snag end toward said peripheral boundary;
- and detent means interposed between said snag member and said body adapted to releasably hold said snag member with its snag end away from said boundary in oppostion to the bias force exerted by said bias means, and upon release to permit said bias means to move said snag member to cause said snag end to move toward said boundary in the absence of some other impediment thereto.
