Abstract: A fastening tool and method of operating a fastening tool can include a driver, a motor, a flywheel driven by the motor, an actuator, and a controller. The actuator can cause the driver to engage with the flywheel to cause the driver to move along an axis. The controller can selectively operate the motor and selectively operate the actuator. In a first state, the controller will not operate the actuator unless the contact trip switch and the trigger switch are both actuated, the contact trip switch being actuated prior to actuation of the trigger switch, and the flywheel is rotating at a first predetermined speed. When the controller is in the first state, the controller can operate the motor to rotate the flywheel at a second predetermined speed until the earlier of a second predetermined period of time after operation of the actuator, or a subsequent operation of the actuator.

Abstract: 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.

Abstract: A fastening tool which controls the return behavior of a driver blade by using a blade stop and/or a bumper. The fastening tool can remove the driver blade from the drive path upon its return after driving a fastener into a workpiece and bring the driver blade to a resting state by using a bumper to orient the driver blade out of alignment with the drive path and into contact the driver blade stop.

Abstract: A fastening tool rafter hook system supporting a power tool includes a power tool round section proximate to a tool handle. The round section has multiple pairs of indexing apertures, each positioned incrementally from a successive pair. A two piece rafter hook system includes: a first piece having a rafter hook band with a semi-circular band portion positioned in direct contact with the round section; and a second piece defining an “L” shaped rafter hook. The rafter hook includes: a first hook portion having first and second indexing bolts connected to the first hook portion; and a second hook portion oriented normal to the first portion. The first and second indexing bolts create detent connections when engaged with the indexing apertures. Connection of the first and second indexing bolts to any pair of indexing apertures releasably retains the rafter hook at selectable predefined orientations on the round section.

Abstract: A mode selector switch for a power tool that can have a source of a magnetic field and use a magnetoresistive component to produce an output signal that changes when the strength of the magnetic field changes. The power tool can have a microprocessor that changes an operational mode of the power tool based on a change of the output signal from the magnetoresistive component. The magnetoresistive component can be a Hall effect sensor and the power tool can be a nailer. The power tool can have a switching means which changes an operational mode based upon a change in the strength of the magnetic field upon a magnetoresistive component. A method of controlling a power tool, having a step of changing an operational mode of a power tool based upon identifying a change in output from a magnetoresistor.

Abstract: A tool chuck includes a body supporting a plurality of jaws, and a sleeve that is operatively connected to the jaw. The sleeve may be rotated to open and close the jaws. The sleeve includes a radial inward facing surface with recesses that are covered by a metal insert. The metal insert provides a metal-to-metal interface for a lock feature.

Abstract: A magazine for use with a fastening tool. The magazine can have a pusher assembly that can be retracted into a recess in the magazine to facilitate loading and reloading of fasteners. The pusher assembly can have a pusher assembly knob which can be reversibly latched to a detent to maintain the pusher assembly in a retracted state. The fastening tool can use a magazine which can be reloaded by a method which has a step of reversibly retracting the pusher assembly into the retracted state to allow for feeding one or more fasteners to the magazine.

Abstract: A fastening tool having a feed funnel adapted to position a nail for driving into a workpiece and which can guide the nail during driving. The feed funnel can be part of a magazine interface, or a nosepiece insert, or the feed funnel can be a unitary part. The feed funnel can also be formed by portions of the magazine interface and the nosepiece insert. Methods using the feed funnel for feeding and driving one or more nails are disclosed.
