Patent ID: 7395862

Claim:
A combination jar and disconnect tool comprising: a housing having an end with threads of a first hand for mating with another threaded component; a sleeve having threads of the first hand on one end for mating with another threaded component, the sleeve slidably disposed within the housing such that the threaded sleeve end is disposed on the tool at an end opposite from the housing threaded end; a plurality of cooperating jarring surfaces disposed on the sleeve and housing; a disconnect joint coupled to either the sleeve or the housing, the interface having threads of a hand opposite to the first handed threads; an axial locking element that fixes the sleeve to the housing against relative axial movement; an anti-rotation element that prevents relative rotation between the sleeve and the housing; a rotational locking element that fixes the disconnect joint together against relative rotation; wherein the axial locking element may be selectively unlocked to allow the sleeve to move axially relative to the housing to impart a jarring force; and wherein the rotational locking element may be unlocked so that relative rotation within the disconnect joint in a first hand tightening direction unscrews the disconnect joint.
