  • Slip release assembly with cone undermining feature
    Patent number: 9771768
    Abstract: A slip release mechanism provides for undermining the slip cone in the set position of the slips so that the grip of the slips can be released subsequent to allowing the cone ramp to flex. The slips can be pulled back down the cone ramp as the completion of the same motion that undermines the support for the cone.
    Type: Grant

  • Relatively movable slip body and wicker for enhanced release capability
    Patent number: 9719316
    Abstract: A slip assembly is in two pieces that move relatively to each other to facilitate release. The wicker portion is dovetailed to the base near a center underside location and at the edges. A positive travel stop converts the initial relative movement into tandem movement of the base and the wicker segment after a predetermined relative movement that has resulted in release. Adjacent components prevent relative movement during the radially outward movement for setting the assembly during which there is tandem movement of the base portion and the wicker portion. The two portions can be initially attached with a breakable member that fails during the release movement.
