Document Type and Number:
Japanese Patent JPS5796190
Kind Code:
A
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.
