  • Patent number: 8174274
    Abstract: A nailer incorporates an integrated stud finder for sensing when a stud is present. The nailer has a work contact element and a magazine for storing nails. The stud finder includes a sensor plate coupled to the work contact element of a nailer and a stud sensing circuit coupled to the sensor plate. The stud sensing circuit is provided for reading a capacitance level and for determining whether the sensor plate is positioned adjacent a stud based upon the capacitance level that is read. The stud finder also includes at least one signaling device coupled to the sensor plate for signaling to a user when a stud is present. The sensor plate is coupled to a no mar tip that is tethered to the nailer. A storage post for storing the no mar tip is positioned on the magazine for storing the no mar tip when not in use.

  • Patent number: 8061573
    Abstract: An fastener driving apparatus has an actuator linked to a work contact element so as to move a trigger plate when the work contact element retracts. A button is movable back and forth along a transverse axis when depressed from its opposite ends. The actuator has a bump mode surface and a sequential mode surface at different locations along the axis, and is moveable transversely back and forth between a bump mode arrangement in which the bump mode surface can move the trigger plate and a sequential mode arrangement in which the sequential mode surface can move the trigger plate. The button is linked to the actuator so as to move the actuator to the bump mode arrangement when depressed from one end, and to move the actuator to the sequential mode arrangement when depressed from the opposite end.
