a from the packer body 10 thereafter continuing upward pulling on the tubing string will retrieve the apparatus a to the surface no twisting or turning is required for disengagement should the operator desire disengagement can be accomplished by twisting since the connection between the apparatus a and the packer 10 is a threaded connection at threads 12 and 14 however in the preferred manner of using the apparatus a the breaking of shear ring 74 allows disengagement by an upward pull which is preferable especially in deep wells where it is difficult to transmit sufficient or substantial torque forces to promote disengagement the apparatus a can further be retained in its initial position shown in fig1 by the installation of additional shear screws through bore 86 in body lock ring housing 64 which is initially aligned with notch 88 on anchor body 28 preferably the shear screw inserted in bore 86 is made of brass bore 90 is an inspection port to allow determination that a gap preferably about one eighth of an inch exists between body lock ring 60 and body lock ring housing 64 when it is insured that such a gap exists a drive pin not shown is inserted in bore 92 which extends through body lock ring housing 64 and body lock ring 60 a set screw not shown is inserted through bore 94 on set down sleeve 44 to secure the engagement between set down sleeve 44 and body lock ring housing 64 at thread 68 as thread 14 is engaged to thread 12 a shoulder 96 see fig1 butts up against a seal unit 98 seal unit 98 is preferably a v ryte type.
