Patent number: 11959348Abstract: A cable head line cutter tool comprising an internal mandrel anchored to a line and releasably held in an initial position by a locking mechanism disposed within an outer housing of the cable head cutter tool. When a tensile load is applied to the line sufficient to overcome a mechanical resistance acting upon the locking mechanism, and maintained for a duration sufficient to overcome a hydraulic resistance acting upon the locking mechanism, the internal mandrel may become released from the locking mechanism and allowed to travel within the outer housing free of the locking mechanism. In embodiments, the cable head line cutter tool may comprise one or more such locking mechanisms acting independently or in coordination. If the tensile load applied to the line is sufficient to release the mandrel from each of the one or more locking mechanisms and maintained for sufficient duration, the mandrel may cause a line cutter device disposed within the cable head line cutter tool to cut the line.Type: GrantFiled: February 28, 2023Date of Patent: April 16, 2024Assignee: Timesaver Downhole Products, LLCInventors: Robert W.

Publication number: 20230212921Abstract: A cable head line cutter tool comprising an internal mandrel anchored to a line and releasably held in an initial position by a pressure relief valve which may act in coordination with a locking mechanism disposed within an outer housing of the cable head cutter tool. When a tensile load is applied to the line sufficient to overcome an opening pressure of the pressure relief valve and a mechanical resistance acting upon the locking mechanism, and maintained for a duration sufficient to overcome a hydraulic resistance acting upon the locking mechanism, the internal mandrel may become released to travel within the outer housing. If the tensile load applied to the line is sufficient to open the pressure relief valve, release the mandrel from the locking mechanism, and maintained for sufficient duration, the mandrel may cause a line cutter device of the cable head line cutter tool to cut the line.Type: ApplicationFiled: January 3, 2022Publication date: July 6, 2023Applicant: TimeSaver Downhole Products, LLCInventors: Robert W.
