  • Power tool safety clutch
    Patent number: 4239096
    Abstract: A devise for sensing sudden abnormal movement of a power operated tool, such as a hand held circular saw or drill. The device, comprising a wrap spring clutch and an inertia sensing means, further rapidly declutches the tool drive in response to the abnormal movement. The declutching reduces the severity of movement where it is power induced and renders the output drive inoperative to improve operator safety. The tool must be positively reset to accomplish further operation.
