Abstract: A fan includes a hub and a plurality of blades extending radially outwardly from the hub and spaced circumferentially about the hub. The plurality of blades includes a reference blade, a first blade, and a second blade. The reference blade is disposed after the first blade in a circumferential direction about the hub. The second blade is disposed after the reference blade in the circumferential direction. The first blade is circumferentially spaced a first distance from the reference blade. The second blade is circumferentially spaced a second distance from the reference blade. The first distance is greater than the second distance.

Abstract: A power tool adapted to impart axial impacts to a tool bit includes a housing having a motor housing portion and a handle portion extending transversely from the motor housing portion, an electric motor supported in the motor housing portion and defining a motor axis, a non-rotatable barrel extending from the motor housing portion and defining a barrel axis parallel to the motor axis, a reciprocation drive assembly coupled to the electric motor and configured to convert torque from the electric motor to reciprocating motion of a piston received within the barrel for reciprocation therein along the barrel axis, a striker received within the barrel for reciprocation in response to the reciprocation of the piston, and an anvil at least partially received within the barrel and positioned between the striker and tool bit.
The anvil communicates axial impacts to the tool bit in response to reciprocation of the striker.

Abstract: The present disclosure is directed to a power tool adapted to impart axial impacts to a tool bit. The power tool includes a housing, an electric motor, and a barrel. The power tool also includes a reciprocation drive assembly coupled to the electric motor and configured to convert torque from the electric motor to reciprocating motion of a piston that is received within the barrel for reciprocation therein. The power tool further includes a striker received within the barrel for reciprocation in response to reciprocation of the piston, and an anvil received within the barrel between the striker and the tool bit. The anvil is configured to communicate axial impacts to the tool bit in response to reciprocation of the striker. The anvil defines an opening and an inner bore that communicates with the opening, and the inner bore at least partially receives a shank of the tool bit.

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 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.
