15 which is coupled by a threaded connection to the liner 13 the tubular hanger member 15 carries at its lower end a tubular j slot sleeve or cage 16 which has j hooks or j slots 16a which are adapted to be releasably connected with respect to j pins 16b on the hanger member 15 the tubular cage 16 has external friction pads or springs 17 which frictionally engage the interior wall 11a of the casing 11 and prevent the cage 16 from relative rotational movement during the latching or unlatching of the j pins from the j hooks the j slot cage 16 is attached by longitudinally extending straps 18 to slip members 19 which are circumferentially disposed about the periphery of the hanger member 15 see also fig2 the slip members 19 have inner tapered surfaces which slide upon an inclined expander cone 20 the expander cone 20 is rotatively mounted on the hanger member 15 between a lower stop shoulder 21 and an upper rotatable bearing 22 fig2 as shown in fig1 and fig3 the liner hanger assembly 10 at its upper end has an internal left hand thread 25 for threaded coupling to a releasable coupling or release nut 27 on a setting tool mandrel 29 the setting tool mandrel 29 has a slidable but non rotatable connection with the coupling nut 27 see fig6 and has a flange 31 below the coupling nut which supports the load of the liner through engagement with the coupling nut.
