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 nosepiece for receiving fasteners from a magazine, a driver blade movable from a ready position toward a driven position during which a fastener positioned in the nosepiece is driven into a workpiece, a lifting mechanism operable to return the driver blade from the driven position toward the ready position for a subsequent fastener driving operation, and a drivetrain to provide toque to the lifting mechanism. The drivetrain includes an electric motor having a motor output shaft, a first gear box coupled to the motor output shaft to receive torque therefrom, a second gear box having an output shaft coupled to the lifting mechanism to provide torque thereto, and a drive shaft having a first end coupled to the first gear box and a second end coupled to the second gear box for transferring torque from the first gear box to the second gear box.

Powered fastener driver having split gear box

A fastener driver includes a housing defining a handle portion, a magazine in which fasteners are held, a nosepiece for receiving fasteners from the magazine, a driver blade movable from a ready position toward a driven position during which a fastener positioned in the nosepiece is driven into a workpiece, a lifting mechanism operable to return the driver blade from the driven position toward the ready position for a subsequent fastener driving operation, and a drivetrain to provide torque to the lifting mechanism. At least a portion of the drivetrain is positioned within and extends through the handle portion of the housing.

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, a canister magazine, and a pusher mechanism coupled to the nosepiece. 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 first side of a fastener within the fastener driver channel. The lockout lever is configured to engage an opposite, second side of 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.
