Abstract: A fastener driver includes a cylinder, a moveable piston positioned within the cylinder, and a driver blade attached to the piston and movable therewith between a top-dead-center (TDC) position and a bottom-dead-center (BDC) position. The driver blade including a body and a plurality of teeth extending therefrom. A lifter is operable to move the driver blade from the BDC position toward the TDC position. The lifter including a plurality of lugs engageable with the teeth of the driver blade when moving the driver blade from the BDC position toward the TDC position. The body of the driver blade has a first thickness and at least a first of the teeth has a second thickness that is greater than the first thickness and the first tooth has a stepped configuration relative to the body.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center position to a bottom-dead-center position for driving a fastener into a workpiece, a drive unit for providing torque to move the driver blade toward the top-dead-center position, and a rotary lifter engageable with the driver blade. The lifter having a body and a drive pin coupled to the body. A roller is positioned on the drive pin and engages with a tooth of the driver blade when moving the driver blade from the bottom-dead-center position toward the top-dead-center position. The roller includes a first engagement section that receives an end portion of the tooth and a second engagement section. An engagement member engages the second engagement section for aligning the first engagement section of the roller with the end portion of the tooth to facilitate meshing between the end portion of the tooth and the roller.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position toward a driven or bottom-dead-center (BDC) position, a gas spring mechanism for driving the driver blade toward the BDC position, a lifter assembly having a rotary lifter for returning the driver blade from the BDC position toward the TDC position, and an arm upon which the rotary lifter is supported. The fastener driver also includes a motor which, in a first position of the rotary lifter, provides torque to the rotary lifter to return the driver blade from the BDC position toward the TDC position. The fastener driver further includes a brake mechanism which, when activated, redirects torque from the motor away from the rotary lifter and toward the arm, causing the lifter assembly to move from the first position toward a second position in which the rotary lifter is not engageable with the driver blade.

Abstract: 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.

Abstract: A power tool including a housing, a trigger disposed on an outside of the housing, the trigger including a magnet, a motor within the housing, the motor configured to produce a rotational output to a drive mechanism, a Hall effect sensor configured to sense a position of the trigger based on a proximity of the magnet to the Hall effect sensor, and an electronic controller connected to the Hall effect sensor. The electronic controller is configured to determine the position of the trigger based on a signal from the Hall effect sensor and control the drive mechanism based on the position of the trigger.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position for driving a fastener into a workpiece and a drive unit for providing torque to move the driver blade from the BDC position toward the TDC position. A kickout arrangement is at least partially defined by an outer surface on one of a torque output member and a torque input member and an aperture formed in the other of the torque output member and the torque input member in which the outer surface is received. The kickout arrangement configured to permit limited rotation of the torque output member relative to the torque input member between a first position and a second position.

Abstract: A fastener driver includes a magazine configured to receive fasteners, a nosepiece including a fastener driving channel from which consecutive fasteners from the magazine are driven, and a workpiece contact element movable relative to the nosepiece between an extended position and a retracted position. A portion of the workpiece contact element is slidably positioned within the fastener driving channel. The portion of the workpiece contact element having an aperture extending therethrough in which the fasteners pass from the magazine through the aperture into the fastener driving channel of the nosepiece to be fired. The portion of the workpiece contact element further includes a guide assembly positioned thereon. The guide assembly configured to guide the fastener along the portion of the workpiece contact element within the fastener driving channel as the fastener is being fired into a workpiece.
