Abstract: A hand tool for applying a ferrule to a safety cable is disclosed having a ferrule positioning device to position the ferrule while a safety cable is placed through the ferrule and through the tool, a mechanism for applying a tension to the cable and a mechanism to crimp the ferrule so as to attach the ferrule to the safety cable. A ferrule holding device, which may contain several ferrules is removably attachable to an elongated body of the hand tool such that one of the ferrules in the holding device is aligned with an opening defined by the elongated body. After threading the safety cable through the ferrule in the ferrule holding device and the opening in the elongated body, it is attached to a tensioning device which applies a predetermined tension to the safety cable. The tensioning device incorporates a clutch which disengages the tensioning device once the predetermined tension has been achieved.

Abstract: The invention relates to a process for applying a ferrule to a lock wire and crimping the ferrule onto the lock wire. The process utilizes a lock wire having a ferrule applied to one end and which is placed through a plurality of threaded fasteners with a free end of a lock wire extending beyond the last of the threaded fasteners. The free end of the lock wire is inserted through a ferrule held in the apparatus and through a tensioning rod. Movement of the tensioning rod exerts a predetermined tension on the lock wire at which time the device crimps the ferrule onto the lock wire to retain it in place at the desired tension.

Abstract: A device is disclosed for automatically inserting a ferrule over a safety cable, tensioning the cable and crimping the ferrule onto the safety cable, and cutting off excess cable. The apparatus is used with a safety cable having a ferrule applied to one end and which is placed through a plurality of threaded fasteners in a pattern. A free end is inserted through a ferrule held in the device and gripped by a tension cylinder. Movement of the tension cylinder exerts a predetermined tension on the safety cable. The device then crimps the ferrule onto the safety cable to retain the safety cable in place at the desired tension. The end of the safety cable extending beyond the attached ferrule is automatically cut off to complete the process.

Abstract: A device and method for connecting together elements such as fasteners using a tension element such as wire or cable extending through the elements includes an installation tool having an elongated handle portion having at its distal end a retaining socket for a ferrule to be permanently crimped to a tensioning element that has been threaded through a series of elements or fasteners to be interconnected by the wire or cable. A tension element movable longitudinally along the tool axis grips the tension wire or cable and withdraws it generally along the axis of the tool handle after the tension element has been threaded through the objects to be connected together until a predetermined tension is applied to the wire or cable. Thereafter, the ferrule is permanently deformed by a punch element so that it is permanently secured to the tension wire or cable, following which the wire or cable outboard of the ferrule is cut to leave the tensioned wire in place with the elements fastened together.
