Wire line running and/or pulling tool

Patent ·
OSTI ID:5475577
A wire line tool is described for running and/or pulling a well tool having a seat thereon and an annular groove about its inner diameter, comprising a body adapted to be raised and lowered on a wire line, latches carried by the body for sliding along guide surfaces on the body which extend downwardly and outwardly with respect to the axis of the body, means on the body cooperable with the seat of the well tool for locating the outer ends of the latches opposite the groove when the body is disposed within the well tool, and means yieldably urging the latches from inner positions to which their outer ends are adapted to move through the the well tool into and out of positions opposite the groove, to outer positions in which their outer ends extend into the groove when opposite thereto. The upper sides of the latches have bearing surfaces which are engageable with the upper end of the groove, when the outer ends of the latches extend into the groove, to support the well tool from the wire line tool, and which are so related to bearing surfaces on the lower sides of the latches which are engageable with the guide surfaces of the body, when the well tool is so supported, as to prevent inward movement of the latches, and means responsive to vertical movement of the body with respect to the well tool for moving the latches inwardly to retract their outer ends from the groove and retain them in retracted positions, so that the wire line tool may be retrieved from the well tool.
