ABSTRACT:
In accordance with an illustrative embodiment of the present invention as disclosed herein, a wireline pulling and running tool can be preset at the surface by simple adjustment for functioning as either a pulling or a running tool, and for release from an associated hanger mandrel by jarring either upwardly or downwardly. A tubular support that carries pivotally mounted gripping elements which are yieldably urged toward disengaged position, has a control body movably mounted therein. The control body has a plurality of sets of circumferentially spaced recess means than can be selectively aligned with the gripping members to enable release thereof in response to vertical movement of the control body from an initial upper or lower position where the body is releasably fixed to the support by a shear pin.
