Abstract: A wire line oil tool adapted for multiple connectors on the bottom. It can be used as an overshot, a fishing neck grapple or an inside grapple. It incorporates an outer body which is annular about a central member. A catch mechanism locks the outer body up or down relative to the inner body. The catch mechanism enables the tool to operate on jarring. On jarring, the two parts move relatively to an up or down position. In the down position, the appendages at the bottom of the tool open to engage a fishing neck or the like. In the up position, it is latched or held. If retrieval of the tool is impeded, subsequent jarring will reverse the catch mechanism and release the fishing neck. The device is particularly adapted to be used on wire line retrieval and running operations. In the event an item is grasped which cannot be retrieved, subsequent jarring will achieve release and retrieval of the tool.
