Abstract
A slip gripping mechanism is shown for supporting a string of cylindrical conduit within the interior bore of a circumscribing well conduit. A cone retaining ring engages a plurality of floating cone segments which define spaced longitudinal slots on the outside of the cylindrical conduit. Vertically shiftable slips are carried in the slots by side edges which engage mating profiles formed in the slots. The slots form guideways for the slips for shifting the slips upwardly and outwardly between a set position engaging the circumscribing conduit and an unset position. Each slip has an arcuate lower surface and a selected width to thickness ratio to allow controlled flexing of the slip in the direction of the circumscribing conduit as the slip moves to the set position.
