Abstract: A power tool includes a housing, a motor positioned within the housing, a controller electrically coupled to the motor, and a transmission coupled to the motor. The transmission includes a ring gear and a torque transducer coupled to the ring gear. The torque transducer is configured to transmit a torque value to the controller. The power tool further including an impulse assembly coupled to the transmission to receive torque therefrom. The controller is configured to receive a target output torque value and to determine an actual output torque based at least in part on the torque value from the torque transducer, and the controller is configured to stop operation of the motor in response to the actual output torque being within a predefined margin of the target output torque value.

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 powered fastener driver comprising a housing, a nosepiece coupled to the housing and extending therefrom, a driver blade movable within the nosepiece between a ready position and a driven position, and a pusher mechanism coupled to the nosepiece for individually transferring collated fasteners in a canister magazine to a driver channel in the nosepiece in which the driver blade is movable. The pusher mechanism includes a feeder arm and a linkage positioned between the feeder arm and the driver blade. The feeder arm is engageable with individual fasteners in the nosepiece for sequentially pushing each of the fasteners into the driver channel in response to movement of the feeder arm toward the driver channel. The linkage is movable to advance the feeder arm toward the driver channel in response to contact with the driver blade as the driver blade moves from the driven position toward the ready position.

Abstract: A reciprocating saw includes a blade assembly having a spindle and a blade clamp. The blade clamp includes a cover rotatably coupled to the spindle, and a detent movable in a radial direction to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The reciprocating saw further includes a barrel surrounding at least a portion of the blade clamp. The barrel includes a plurality of projections extending from the barrel toward the blade clamp. At least one of the projections is engageable with the cover to rotate the cover from the second rotational position to the first rotational position, thereby adjusting the blade clamp from the unlocked configuration toward the locked configuration.
