Abstract: A fastener driver includes housing having a handle portion. A trigger is mounted to the handle portion. A magazine is coupled to the housing and configured to receive fasteners. The fastener driver further includes a nosepiece through which consecutive fasteners from the magazine are driven. The fastener driver further includes a dry-fire lockout mechanism having a latch pivotably coupled to the magazine, and a link is coupled to the trigger for movement with the trigger. The latch is pivotable between a first position, in which the latch is disengaged from the link, and a second position, in which the latch is engaged with the link and inhibits movement of the link, and therefore the trigger, in response to the trigger being depressed. The latch moves from the first position to the second position in response to a number of fasteners remaining in the magazine being less than a predetermined value.

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 for driving a fastener into a workpiece, a gas spring mechanism for driving the driver blade toward the BDC position, and a lifter assembly having a rotary lifter for returning the driver blade from the BDC position toward the TDC position. The powered fastener driver further includes an arm upon which the rotary lifter is supported, 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, and a brake mechanism including an electromagnet which, when activated, causes the rotary lifter to move from the first position toward a second position in which the rotary lifter is not engageable with the driver blade.

Abstract: A powered fastener driver including a housing defining a cylinder support portion with a cylinder and a motor housing portion. The driver includes a piston and a driver blade. The piston is movable within the cylinder from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position with a blade attached thereto for driving a fastener. The driver includes a lifter for moving the piston and blade, in unison, from the BDC position toward the TDC position. The driver includes a nosepiece from which the fastener is discharged, a motor disposed in the motor housing portion, a fan coupled to the motor to receive torque therefrom, causing the fan to generate an airflow, and a conduit for directing the airflow to at least one of away from the cylinder to clear and/or prevent debris accumulated in the cylinder support portion of the housing, or toward the cylinder for cooling the cylinder.

Abstract: A working element operable to expand an end of a tube includes a main body configured to rotate about an axis, a plurality of roller supports movably coupled to the main body, the roller supports movable relative to the main body between a retracted position and an expanded position, and a plurality of rollers coupled to the roller supports such that a distance between a first roller of the plurality of rollers and a second roller of the plurality of rollers increases when the roller supports move toward the expanded position. The rollers are configured to be inserted into the end of the tube when the roller supports are in the retracted position, and the rollers are engageable with an inner circumference of the tube when the main body rotates about the axis to expand the end of the tube.

Abstract: A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, a driver blade attached to the piston and movable between a ready position and a driven position, a lifter engageable with the driver blade to return the driver blade from the driven position to the ready position, and a multi-stage planetary transmission including an output shaft operatively coupled to the lifter to provide torque thereto, a first bearing supporting a first portion of the output shaft for rotation, a second bearing supporting a second portion of the output shaft for rotation, and first and second planetary stages. The fastener driver also includes a housing having a cylinder support portion and a transmission housing portion in which the first and second bearings are received. The cylinder support portion and the transmission housing portion are integrally formed as a single piece.

Abstract: A rotary hammer adapted to impart axial impacts to a tool bit. The rotary hammer includes a housing, a motor supported by the housing, a spindle coupled to the motor for receiving torque from the motor, causing the spindle to rotate, a reciprocation mechanism operable to create a variable pressure air spring within the spindle, an anvil received within the spindle for reciprocation in response to the pressure of the air spring, the anvil imparting axial impacts to the tool bit, a bit retention assembly for securing the tool bit to the spindle, and an electromagnetic clutch mechanism switchable between a first state, in which the reciprocation mechanism is enabled, such that the anvil imparts axial impacts to the tool bit, and a second state, in which the reciprocation mechanism is disabled, such that the anvil ceases to impart axial impacts to the tool bit.

Abstract: A power tool includes a housing, a motor positioned within the housing, and an impulse assembly coupled to the motor to receive torque therefrom. The impulse assembly includes a cylinder at least partially forming a chamber containing a hydraulic fluid, an anvil positioned at least partially within the chamber, and a hammer positioned at least partially within the chamber. The hammer includes a first side facing the anvil and a second side opposite the first side. The impulse assembly further includes a biasing member biasing the hammer towards the anvil, and a valve movable between a first position that permits a first fluid flow rate of the hydraulic fluid in the chamber from the second side to the first side, and a second position that permits a second fluid flow rate of the hydraulic fluid in the chamber from the first side to the second side.

Abstract: An oscillating power tool includes a housing, a motor, a tool holder driven oscillatingly, a flange threadedly coupled to a plunger, and a lever pivotable between a clamping position and a release position. The flange is configured to be movable in an axial direction. The flange is configured to clamp the output element onto the tool holder in the clamping position and configured to be displaced a first distance from the tool holder in the release position. The lever includes a cam surface including a substantially flat surface configured to engage the plunger in the release position. In the release position, a gap is disposed between the lever and the housing to allow the lever to be rotated past the release position. The lever is configured to displace the flange a second distance from the tool holder, larger than the first distance, when rotated past the release position.

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.
