ABSTRACTA liner hanger is shown of the type used to hang a wellliner in a surrounding well bore. The hanger includes atubular mandrel which is connectible in a liner string. Aset of circumferentially-spaced gripping slips are mountedabout the mandrel with each slip having a spring armextending therefrom in alignment with the axis of themandrel, A tapered, slip expander cone is mounted on themandrel exterior above each of the slips for expanding theslips radially outwardly in the direction of the surroundingwell bore responsive to opposite relative movement of theslips and cones. At least one channel guide is formed on theexterior of the mandrel in longitudinal alignment with one ofthe expander cones. The channel guide includes a slotportion for slidably receiving the spring arm of one of thegripping slips for supporting the slip on the exterior of themandrel. A setting mechanism urges the slips in thedirection of the cones to effect the outward, radialexpansion of the slips to thereby hang the mandrel, and, inturn, the liner within the well bore.
