  • Patent number: 11008994
    Abstract: A specialty nut and specialty ratchet driver device used to start an internal combustion engine, each with an integrated one direction clutch, designed to be an attachment for a commercially available battery operated drill/driver gun. The specialty ratchet driver with an integrated one direction clutch is inserted into the driver receptacle of the socket placed over the nut on the crank shaft of the engine. One end of a drive shaft is inserted into the one direction clutch portion of the specialty ratchet driver device and the other end of the drive shaft is inserted into the chuck of a battery operated drill/driver gun. The torque of the drill/driver gun turns the crank shaft of the engine with sufficient force to initiate starting of the engine. The one direction clutch then allows the engine to turn faster than the drill/driver so as not to impede the engine start up.

  • Publication number: 20180195484
    Abstract: A specialty nut and specialty ratchet driver device used to start an internal combustion engine, each with an integrated one direction clutch, designed to be an attachment for a commercially available battery operated drill/driver gun. In the case of the specialty nut, it is screwed onto the crank shaft of a small internal combustion engine with the integrated one direction clutch pointing outward. One end of a driver shaft is inserted into the one direction clutch and the other end of the shaft is inserted into the chuck of a battery operated drill/driver gun. In the case of the specialty ratchet driver device, a standard nut is present on the threaded engine crank shaft and a socket is placed over that nut. The specialty ratchet driver with an integrated one direction clutch is inserted into the driver receptacle of the socket placed over the nut on the crank shaft.

  • Patent number: 9587615
    Abstract: A device designed to be a fixture for a commercially available battery operated drill/driver gun to start an internal combustion engine such as a model airplane engine by pressing the device onto the nose cone of the engine. The portion of the device which comes into contact with the nose cone of the engine is a cylinder connected to a shaft with a one way clutch. A rubber or silicone adapter is inserted into the cylinder attached to the shaft; the adaptor cone of the engine fits into the rubber or silicone adapter on the device.

  • Publication number: 20160201839
    Abstract: A device designed to plug the flexible fuel fill line of a model airplane engine fuel tank to prevent it from leaking. The plug portion of the device is a sphere which fits into the flexible fuel fill line terminating at a cross member. The opposite end of the device contains a semi-circular clasp which attaches around the flexible fuel fill line so that the device stays attached to the flexible fuel fill line when the sphere plug portion is removed from the flexible fuel fill line.

  • Patent number: 5305511
    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.

  • Patent number: 5167059
    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.

  • Patent number: 5152043
    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.

  • Patent number: 5127144
    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.
