摘要： A powered hand-held fastening tool includes a housing defining a handle, a frame, a motor-driven flywheel journaled to the frame, and an elongated driver that is selectively coupled to the flywheel to drive a fastener into a workpiece. The flywheel and driver have complementary sloped surfaces that mesh with each other to transmit energy from the flywheel to the driver to accelerate the driver along the driver axis. A follower assembly for selectively coupling the driver to the flywheel includes a solenoid actuator.

摘要： A power tool includes a housing, a motor disposed in the housing, an output spindle configured to be driven by the motor, an input switch, and a controller configured to control power being delivered to the motor. The controller is operable in one of: (a) a normal mode where the controller causes continuous electric power to be delivered to the motor during actuation of the input switch in a first range of positions; and (b) a feathering mode where the controller causes discontinuous electric power to be delivered to the motor during actuation of the input switch in a second range of positions that is different from the first range of positions motor to simulate feathering the input switch.

摘要： A powered hand-held fastening tool includes a housing defining a handle, a frame, a motor-driven flywheel journaled to the frame, and an elongated driver that is selectively coupled to the flywheel to drive a fastener into a workpiece. A follower assembly for selectively coupling the driver to the flywheel includes a solenoid actuator, a biasing mechanism, a lever arm connected between the solenoid actuator and the biasing mechanism, and an intermediate member having journaled thereto a pivot roller and a pinch roller. Upon energization of the solenoid the lever arm is moved in a direction parallel to the drive axis, thereby applying a force on the pivot roller perpendicular to the drive axis, causing the pinch roller to press the driver against the flywheel and initiate the drive stroke. The intermediate member pivots about the pivot roller to release the pressure on driver upon completion of the drive stroke.

摘要： Compression return springs can be mounted on rails between the driver and an impact absorber. The springs include a plurality of wires twisted together to form a multi-stranded twisted wire member, which forms the coils of the spring. The springs can have an inner diameter that resists movement of the coils along the rails when the spring is at its free length, but has a mounted inner diameter that freely allows such movement. The coil-to-coil pitch of the spring can vary along its length. A motor initially rotates the flywheel without engaging the driver. The driver then contacts the rotating flywheel to propel the driver, which compresses the return springs against the impact absorbers as the driver travels from the returned position to the extended position.

摘要： A powered tool follower assembly can include a solenoid plunger that is movable longitudinally in a direction aligned with a drive axis in response to energization of the solenoid and a biasing mechanism with a spring axis extending transversely to the drive axis. A lever arm can extend between the plunger and the biasing member and couple the plunger to the biasing mechanism. A pinch roller can be disposed between the lever arm and the driver. Energization of the solenoid can move the plunger longitudinally, causing relative movement between the lever arm and the drive wheel that forces the pinch roller into engagement with the driver and transfers a biasing force from the compression spring through the lever arm and pinch roller to the driver to pinch the driver between the pinch roller and the flywheel and drive the driver along the driver axis.

摘要： A flywheel-driven tool includes a ferromagnetic driver. The driver has a firing position in which the driver is drivingly engaged against the flywheel. The driver also has a home position radially further away from the flywheel than the firing position when the flywheel is spinning in preparation to firing the driver. A magnet is positioned adjacent the driver to exert a magnetic force on the driver to pull the driver into the home position.
