A fastener driver includes a pusher assembly slidably coupled to a magazine assembly. The pusher assembly includes a first portion and a second portion that are selectively movable relative to each other. The pusher assembly is adjustable between a first state in which the first portion and the second portion are configured to move together in unison toward the channel, and a second state in which the first portion moves relative to the second portion toward the channel. A dry-fire lockout assembly includes a blocking member coupled to the magazine assembly or the nosepiece assembly, and a lockout member selectively engageable with the blocking member for moving the blocking member from a first position and a second position. The pusher assembly is configured to transition from the first state to the second state after a predetermined number of fasteners remain in the magazine assembly.

Powered fastener driver

A clutch can include an input; an output; a centrifugal clutch mechanism that transfers energy from the input to the output, the centrifugal clutch mechanism including: a disk; centrifugal weights movably coupled to the disk; and a central shaft rotatable relative to the disk and extending through the disk, the central shaft comprising drive surfaces, wherein the disk is rotatably coupled to the input, wherein the output is rotatably coupled to the central shaft, wherein the centrifugal weights rotate between a disengaged position in which the centrifugal weights do not interface with drive surfaces and an engaged position in which the centrifugal weights interface with the drive surfaces, and wherein the centrifugal weights are disposed inside the perimeter of the disk when the centrifugal weights are in the engaged position.

Clutch mechanism

A powered fastener driver comprising, a housing including a head portion, a handle portion extending therefrom, the handle portion including a first end coupled with the head portion and an opposite, second end, and a drive unit portion, and a canister magazine configured to receive coiled fasteners. At least a portion of the canister magazine is integrally formed as a single piece with at least a portion of the drive unit portion of the housing.

Magazine for powered fastener driver

A powered fastener driver includes a housing, a nosepiece having a fastener driver channel from which fasteners are discharged into a workpiece, a driver blade, a workpiece contact element, and a pusher mechanism. The powered fastener driver also includes a dry-fire lockout mechanism having a lockout lever movable between a bypass position and a blocking position and a last fastener holding member configured to engage a fastener within the fastener driver channel. The lockout lever is configured to engage the fastener within the fastener driver channel. The last fastener holding member biases the fastener within the fastener driver channel toward an inner surface of the fastener driver channel to inhibit the fastener from falling out of the fastener driver channel.

Dry-fire lockout and last fastener retention mechanism for powered fastener driver

A powered fastener driver includes a housing, a nosepiece coupled to the housing and extending therefrom, a driver blade, a canister magazine coupled to the nosepiece, a pusher mechanism coupled to the nosepiece, and a cam. The pusher mechanism includes a body coupled to the nosepiece, a feeder arm pivotably coupled to the body, and a lever pivotably coupled to the nosepiece. The lever has a first end that is engageable with the body for imparting reciprocating translation to the body relative to the nosepiece in response to pivoting movement of the lever in opposite directions about the pivot axis. A cam is engaged with a second end of the lever for imparting pivoting movement to the lever. The feeder arm is engageable with individual fasteners in the nosepiece for sequentially pushing the fasteners into the driver channel in response to reciprocation of the body relative to the nosepiece.

Pusher mechanism for powered fastener driver

A fastener driver includes a housing, a cylinder supported by the housing, and a moveable piston positioned within the cylinder. A driver blade is attached to the piston and movable therewith between a top-dead-center (TDC) position and a driven or bottom-dead-center (BDC) position. The driver blade includes a body portion extending along a longitudinal axis, and a tip portion configured to contact a fastener. The tip portion is bisected by a central axis that is parallel with the longitudinal axis such that the tip portion is laterally offset relative to the body portion.

A fastener driver includes a housing, a cylinder supported by the housing, and a moveable piston positioned within the cylinder. A driver blade is attached to the piston and movable therewith between a top-dead-center position and a driven or bottom-dead-center position. The driver blade includes a body having a first side and an opposite, second side with the driving axis passing therebetween, a plurality of teeth extending from the first side of the body, and a plurality of projections extending from the second side of the body. The body and the projections are bisected by a common plane. The teeth extend at an oblique angle from the first side of the body relative to the common plane.
