Patent GB-2147336-A (GB)
Title: Wire line running and/or pulling tool
Inventor: AKKERMAN NEIL HOOVER
IPC: E21B31/20
Filed: 1984-08-31
Abstract: There is disclosed a wire line tool 10 for use in running and/or pulling a well tool 15 within a well bore. Latches 20 are carried within slots 19 about a body 11 of the running tool 10 which is adapted to be raised and lowered on a wire line WL. The latches 20 are 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 16 in the well tool 15 when opposite thereto. The outer ends of the upper sides of the latches 20 have bearing surfaces which, when their outer ends extend into the groove 16, are engageable with the upper end 25 of the groove 16 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 slidable over guide surfaces on the lower sides of the slots as to prevent inward movement of the latches when the well tool is raised or lowered with the wire tool. The latches 20 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 tool to be retrieved from the well tool. <IMAGE>
