ABSTRACT:
An apparatus for remotely cutting a broken guideline extending from an underwater guide post comprising a frame, a clamping mechanism for clamping the frame to the guide post in a predetermined location, a pair of opposed cutting jaws pivotally coupled to the frame, and a remotely actuated power device for pivoting the jaws across the longitudinal axis of the broken guideline to sever the guideline from the guide post. The cutting jaws are pivoted about the same axis and are actuated by a U-shaped driver slidably movable along the frame. The clamping mechanism comprises a pair of opposed jaws receivable in an annular groove in the guide post. Above the cutting jaws are a pair of pivotal loom jaws which guide the assembly on the post and also deflect any interfering portion of the broken guideline extending along the side of the post.
