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.

Power tool having latched pusher assembly

A fastening tool includes a contact trip operatively associated with a contact trip switch to enable a fastener drive system to be fired when the contact trip reaches a firing position, after having engaged a work surface. If a dry-fire condition exists in a magazine connected to the fastening tool, the movement of the contact trip is completely taken up or absorbed by a biasing agent so that the contact trip switch is not closed. The biasing agent also limits the amount of force that can be applied to the contact trip switch in the event an operator slams the contact trip against a work surface or drops the fastening tool nose-first onto an unyielding surface.

Dry-fire bypass for a fastening tool

A fastening tool having a nail stop which positions a nail for driving and is made at least in part of a contact material which can be investment cast and/or hardened. The contact material can resist wear from the action of driving the nail and the movement of a driver blade. The nail stop can be configured to align nails fed from a magazine and can be offset from the longitudinal centerline of the fastening tool. The nail stop can have a head contact length which is 0.5% to 95% of the length of the nail to be driven. The nail stop is used in methods for positioning a nail for driving.

Fastening tool nail stop

A power tool including an activation arm assembly having an actuator coupled to the activation arm assembly, the activation arm assembly being coupled to the structure and including a roller assembly having a roller, wherein actuation of the actuator causes the roller assembly to translate toward and engage the driver to initiate driving engagement between the driver and the flywheel; The activation arm assembly further includes a follower arm that engages the roller, the follower arm including a first mounting portion and a second mounting portion, the second mounting portion being pivotally coupled to the actuator and slidingly engaged with the carriage, the first mounting portion being biased in a direction toward the driver. The follower arm has a non-linear profile.

Activation system having multi-angled arm and stall release mechanism

A fastening tool having a lockout mechanism which has a dry fire lockout which achieves a controlled lockout override. The lockout mechanism can be part of a fastening tool magazine, a pusher assembly or a nosepiece contact trip. The lockout mechanism can be an angled lockout, a torsion spring lockout, or a fixed member lockout. The fastening tool can have a method of controlling lockout override using a lockout control angle.

Power tool having angled dry fire lockout

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 magazine can also use a lockout mechanism which allows an operator to know when it is appropriate to reload fasteners and which can mitigate damage resulting from an impact upon the fastening tools nosepiece when the lockout mechanism is engaged. The fastening tool can also have a contact trip actuator which is compact and can control the amount of force that is applied to a tactile switch of the fastener driving mechanism.

Magazine assembly for fastening tool

A trigger mechanism for a fastening tool having a spring curl trip actuator. The spring curl trip actuator can be made of a flexible material and can be configured to exert a force upon a trigger switch. The spring curl trip actuator can also absorb force from a contact trip. The spring curl trip actuator can have compact height and length dimensions. The fastening tool can use a method for controlling triggering by using a spring curl trip actuator.

Power tool raving spring curl trip actuator

A nosepiece assembly for a fastening tool that has a contact surface made of a contact material. The contact surface can provide the nosepiece assembly wear resistance against the action of nails and/or a driver blade of a nailer. The nosepiece assembly can optionally have one or more of a nosepiece insert, a nail stop and a blade guide, each of which can be made at least in part of the contact material. The contact material can be investment cast.

Fastening tool nosepiece insert

A fastening power tool such as a nailer is provided including a tool housing, an input unit actuated in response to an operator input, and a motor assembly including a motor housed within the tool housing. A control unit is provided including a controller programmable to control an operation of the motor and a decoder circuit configured to control a supply of power from a power source to the controller based on a status of the power source and a status of the input unit. The decoder circuit is configured to connect supply of power from the power source to the controller when the power tool is coupled to the power source prior to an engagement of the input unit, but disconnect the supply of power when the power tool is coupled to the power source after the engagement of the input unit.

Control system for a fastening power tool

A nail channel for a fastening tool. The nail channel can be a unitary piece or have a variety of parts. The nail channel can have a first portion provided by a fastener magazine and a second portion provided by a nosepiece insert. The nail channel can be formed when the nosepiece insert is reversibly engaged with a nose end of a nailer magazine. The nail channel can also position a fastener, such as a nail, for driving into a workpiece. Methods of forming and using the nail channel are also disclosed.
