a provides an example of the present invention apparatus 10 includes four principal sub assemblies attached to a tool 11 located in a wellbore 18 first sub assembly 12 includes an upper member 14 secured to the lower end of wireline 16 second sub assembly 20 is lower than first sub assembly 12 and is attached to first sub assembly 12 third sub assembly 24 is a tube and spring arrangement in communication with second sub assembly 20 and the fourth sub assembly 25 fourth sub assembly 25 is attached to third sub assembly 24 and is also attached to the down hole tool wellbore 18 as illustrated is free of any squeezes or impediments fig1 b illustrates tool 11 stuck below obstruction 26 an end user located topside to the wellbore 18 would know of the blockage caused by obstruction 26 as the wireline 16 would no longer be moved upward in the wellbore apparatus 10 will then be fully extended showing the intersections between sub assemblies 12 20 and 24 during this time none of the springs in sub assemblies 12 20 and 24 are constricted and the springs do not store any spring energy see fig2 a d for spring locations fig1 c illustrates the tension on wireline 16 being removed whereby the weight of apparatus 10 will cause apparatus 10 to contract due to gravity when apparatus 10 is contracted the springs located in sub assemblies 12 20 and 24 will contract storing compression energy in the fully contracted state apparatus 10 is primed and its internal springs tightened fig2 a d the energy stored in.
