摘要： In a drill string jar apparatus having an elongated tool body positionable within a drill string, which would also include a latch mandrel movable within a bore of the tool body between a first neutral position and fired up or fired down positions; a substantially continuous channel formed in the interior wall of the tool body, a shoulder portion on the exterior wall of the latch mandrel body for latching into the channel of the tool body when the mandrel is in the neutral position and slots in the wall of the latch mandrel for allowing the mandrel body to flex inwardly sufficiently to disengage the shoulder portion from the channel in the tool body and allow the latch mandrel to move upward or downward within the bore of the tool body depending upon the direction of the force imparted on the mandrel and make contact with the upper or lower end of the tool in order to dislodge a tool below the jar apparatus.

摘要： An oil well wireline cable catcher apparatus includes a housing having a bore which passes vertically therethrough so that a wireline can pass vertically therethrough and then into the oil well bore. Sensing means are also included to monitor tension of the wireline. Slips are disposed within the housing on opposite sides of the wireline between gripping and retracted positions. Each slip has a wireline engaging surface, the pair of respective surfaces facing one another so as to grip the wireline when the slips are actuated to the gripping position. A pair of springs mounted in the housing are respectively beneath each slip, the springs biasing the slips toward the retracted position so that the wireline is not engaged by the slip surfaces. A slip actuator means is carried by the housing and is cooperatively connected to the sensing means for moving the slips together to grip the wireline responsive to a break in the wireline and attentive relaxation in wireline tension.
