  • Core barrel adjusting system
    Patent number: 5025872
    Abstract: The present invention comprises a novel core drilling tool system which allows for less stressful extended axial settings and adjustments in a core barrel environment. More particularly, the present invention discloses the formation of the setting device as a separate spacer apparatus which provides a setting method independent of the suspension of the inner unit in the outer housing of a core drilling tool thereby allowing for axial settings over a long adjustment path which are generally free of stress due to the weight of the inner unit.
