ABSTRACT:
These are disclosed three embodiments of a wire line tool for use in running and/or pulling a well tool within a well bore. In each embodiment, latches are carried about a body of the wire line tool and yieldably urged from inner positions, in which their outer ends are adapted to move into the well tool, to outer positions in which their outer ends extend into a groove in the well tool when opposite thereto. The wire line tool may be latched to the well tool at the surface for the purpose of running it into the well tool, or lowered into a well bore and latched to a well tool therein for the purpose of pulling the well tool. The latches are forced inwardly to remove their outer ends from the groove, and then retained against outward movement, in response to downward jarring of the body and subsequent lifting of the body with the wire line to permit the wire line tool to be retrieved from the well tool following running of the well tool into the well bore.
