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 rotary lifter is engageable with the driver blade and configured to receive torque from the drive unit for returning the driver blade from the BDC position toward the TDC position. The lifter has a body, a drive pin coupled to the body, and a roller positioned on the drive pin. The roller includes an engagement section configured to receive an end portion of a tooth of the driver blade. The lifter includes a means for aligning the engagement section with the end portion of the tooth on the driver blade to facilitate meshing between the end portion and the roller.

Abstract: A fastener driver includes a magazine having a magazine cover and a magazine body. The magazine cover includes a top surface having an opening defined therein. The magazine body is slidably movable relative to the magazine cover from a closed position to an open position. A latch is coupled to the top surface of the magazine cover and extends through the opening in the top surface of the magazine cover. The latch includes a latch projection that defines a first contact surface. A pusher body is slidably coupled to the magazine body and includes an arm member that defines a second contact surface. A biasing member biases the pusher toward a nosepiece when the magazine body is in the closed position. The first and second contact surfaces are engageable to hold the pusher body in a latched position when the magazine body is in the open position.

Abstract: A powered fastener driver includes a driver blade and a drive unit having an output shaft for providing torque to move the driver blade from the bottom-dead-center position toward the top-dead-center position. A rotary lifter is engageable with the driver blade and configured to receive torque from the output shaft of the drive unit in a first rotational direction for returning the driver blade from the bottom-dead-center position toward the top-dead-center position. A kickout arrangement is defined between the lifter and the output shaft and configured to permit limited movement of the lifter relative to the output shaft between a first position and a second position. The kickout arrangement having a curvilinear slot defined in the rotary lifter in which a portion of the output shaft is received. Movement of the rotary lifter from the first position toward the second position causes the slot to move relative to the output shaft, while the output shaft remains within the slot.

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 gas spring-powered fastener driver includes a cylinder, a storage chamber cylinder having pressurized air in communication with the cylinder, a moveable piston positioned within the cylinder, a driver blade extending from a first side of the piston and movable therewith between a top-dead-center position and a bottom-dead-center position, a one-way seal carried onboard the piston and disposed between the piston and the cylinder, the one-way seal being configured permit a bypass flow of pressurized air from the first side of the piston, past the one-way seal, and into a space within the cylinder adjacent an opposite, second side of the piston during movement of the piston and driver blade from the top-dead-center position to the bottom-dead-center position, thereby increasing a pressure of the pressurized air within the cylinder and storage chamber cylinder, and a pressure relief valve in fluid communication with the storage chamber cylinder.
