• (3) raising said tubular means extendible to the top of the well to remove said carriage means within said slot means from initial running position;
• (4) shifting said tubular member extending to the top of the well rotatably and longitudinally downwardly to cause said carriage means to travel in said slot means to position for anchoring said liner within said well bore and on said casing and for shifting said longitudinally shiftable tubular body downwardly with respect to said sleeve means to cause said expander means carried by said tubular body to engage said gripping means carried on said sleeve means and move said gripping means outwardly into gripping engagement with said well bore casing;
• (5) rotating said tubular member extendible to the top of the well to release said tubular running tool from said longitudinally shiftable body for subsequent retrieval of said running tool out of said well bore;
• and (6) injecting within said tubular member extendible to the top of the well a cement slurry pumpable through said tubular member, said apparatus and said liner, for subsequent setting in said well bore between said well bore and said liner to affix said liner in said well bore.
