  • Pneumatic fastener driving tool and an electronic control system therefore
    Patent number: 6431425
    Abstract: An electronically controlled pneumatic fastener driving tool. The tool is of the type having a body containing a cylinder with a piston/driver assembly therein, a firing valve actuable to introduce high pressure air into the cylinder to cycle the piston/driver assembly, a manual trigger, a safety trip, and an electronic control system. The electronic control system comprises a remote solenoid valve to actuate the firing valve, a microprocessor having inputs from at least the trigger and safety trip and an output to energize the solenoid of the remote valve to cycle the tool, a battery to energize the microprocessor and a rechargeable battery to energize the solenoid of the remote valve. The microprocessor determines the mode of operation of the tool and may be designed to provide two or more modes selectable by a mode selection switch. The input from the trigger is provided with a reed switch closable by the trigger and the input from the safety trip is provided with a reed switch closable by the safety trip.
