  • Patent number: 4423697
    Abstract: A fluid activated cable locking device for cable, chain, wire, tow etc. particularly for securing an anchor chain, pendant wire or the like on board a marine vessel, comprising a preferably cylindrical housing, in which housing a preferably hydraulic jack is arranged substantially axially, said jack having a cylinder rigidly connected with the housing, and a piston rod connected with a jaw means having a pair of locking jaws that are moved towards/from one another by extracting/withdrawing the piston rod from/into the jack cylinder. The housing with the jaw means and the jack is mounted vertically displaceable in a correspondingly shaped cylindrical well, such as in a vessel deck structure. The vertical displacing movement is carried out by means of additional jack means connected between the jaw housing and the deck structure so the locking jaw means can be stored under the deck lever when not in use.
