An anchor for hooking and cutting a submarine cable comprises an anchor body part, a cable-hooking part and a connecting part, these parts being connected together into a form like a fishing hook. A cable-sensing device is provided on the inner side of the connecting part and spring-biased in the floating-up direction. A cutting device is provided for cutting and holding the submarine cable by being advanced from the anchor body part by hydraulic pressure making use of a force such as sea water pressure or a tugging force for raising the submarine cable externally applied to the anchor body part when the cable-sensing device is caused to sink against the biasing force in the floating-up direction by receiving the tension in the cable hooked on the inner side of the connecting part.
An anchor for hooking, cutting and holding an underwater marine cable, comprising a body means having a hook-like configuration in that said body means has a cable-receiving channel which leads to a closed end such that in hooking a cable, the cable moves along said channel to said closed end, cable-responsive means mounted on said body means at said closed end and operable to be engaged by a cable which has been hooked, cutter-gripping means mounted on said body means for cutting said hooked cable and for gripping one end of the cut cable such that said gripped one end of said cable can be raised by said anchor, and cylinder-piston means operably connected between said cable-responsive means and said cutter-gripper means for utilizing the ambient liquid pressure as a source of power for powering said cutter-gripping means to effect a cutting action on a hooked cable upon being actuated by said cable-responsive means, said cylinder-piston means comprising buffering means utilizing a compressible gas medium for buffering the effect of the ambient liquid pressure applied to said cutter-gripping means during said cutting action.
An anchor for hooking, cutting and holding a marine cable comprising a body means having a hook-like configuration in that said body means has a cable-receiving channel which leads to a closed end such that in hooking a cable, the cable moves along said channel to said closed end, cable-responsive means mounted on said body means at said closed end and operable to be engaged by a cable which has been hooked, cutter-gripping means mounted on said body means for cutting said hooked cable and for gripping one end of the cut cable such that said gripped one end of said cable can be raised by said anchor, and cylinder-piston means utilizing a liquid and having a passage means for said liquid leading to said cutter-gripper means for powering said cutter-gripping means to effect a cutting action on a hooked cable upon being actuated by said cable-responsive means, said cable-responsive means comprising an elongated accommodation hole in said body means and having a longitudinal axis, a cable-sensing block reciprocably mounted in said accommodation hole, biasing means in said accommodation hole biasingly urging said cable-sensing block to a non-actuated position such that when a cable is hooked, the hooked cable moves said cable-sensing block in said accommodating hole from said non-actuated position to an actuated position, said cutter-gripping means further comprising a cutter-gripper part movable along a linear path between a non-actuated and an actuated position, said linear path being perpendicular to said longitudinal axis of said accommodation hole, said cutter-gripper part engaging said cable-sensing blck when said cutter-gripper part and said cable-sensing block are in their non-actuated positions.
An anchor connected to an anchor line and operable for hooking, cutting and holding a marine cable, comprising a body means having a hook-like configuration in that said body means has a cable-receiving channel which leads to a closed end such that in hooking a cable, the cable moves along said channel to said closed end, cable-responsive means mounted on said body means at said closed end and operable to be engaged by a cable which has been hooked, cutter-gripping means mounted on said body means for cutting said hooked cable and for gripping one end of the cut cable such that said gripped one end of said cable can be raised by said anchor, and cylinder-piston means utilizing a captured liquid medium and having a passage means for said liquid medium leading to said cutter-gripper means for powering said cutter-gripping means to effect a cutting action on a hooked cable upon being actuated by said cable-responsive means, said cylinder-piston means comprising pull means for connecting the anchor to an anchor line and operable to utilize the pulling force of the anchor line to increase the pressure of the captured liquid medium in said cylinder-pressure means, whereby the pulling force on said anchor line is utilized in effecting cutting of said hooked cable.
