tool employing the slips 10 and 12 the upper slips 10 and 12 are released by an upward pull on the mandrel 30 this upward pull brings up ring 50 which in turn via sleeve 54 pushes on lower end 56 of each of the keys 42 as keys 42 move up pin 46 which extends through keys 42 and into cone 22 is sheared as illustrated in fig3 and 3a because the upper end of each of the keys 42 is tapered the side walls 58 and 60 converge as they present themselves adjacent the top of cut out 40 near bore 48 as a result the circumferential support presented by cone 22 onto side walls 18 and 20 is undermined as edges 62 and 64 of cut out 40 have the opportunity under load to flex toward each other once edges 62 and 64 are free to flex circumferentially toward each other the side walls holding edges 18 and 20 can move away from each other reducing or eliminating the wedging force on slips 10 and 12 wherein an upward pull on handle 32 of the slips 10 and 12 easily dislodges teeth 26 from casing 28 up until the time that pin 46 is sheared the cone 22 has a rigid cylindrical structure and the slips 10 and 12 are firmly wedged along their edges 18 and 20 to the cone 22 however with.
