Abstract : The patent relates to a grapple for hoisting an undersea cable having first and second cable engaging jaws which are normally biased in a closed position. The first and second jaws are pivotally connected to a guide plate at a common pivot point and a restraining wire is provided to keep the jaws in an opened position. Upon locating a cable undersea, the restraining wire is severed and the biased jaws are closed around the cable. A cam surface is provided on the guide plate and a shaft which is attached by linkage to the first and second jaws moves onto the cam surface to lock the jaws in a closed position around the cable to be recovered.
