Abstract
In the several representative embodiments of well bore apparatus disclosed herein adapted for releasable connection to a suspension cable, a cable-cutting member is arranged within an upper portion of the well bore apparatus for parting the lower end portion of the cable connected to the apparatus. In the disclosed embodiments of the invention, the cutting member is retained in an inactive position and chemically-degradable securing means are cooperatively arranged to fail only upon the elapse of a prolonged time interval so as to actuate the cable-cutting member should the apparatus have become stuck in a well bore. Provisions are also made for replacing the securing means upon return of the apparatus to the surface before the expiration of the predetermined time interval.
