Abstract: A powered fastener driver including a housing, an inner cylinder within the housing, and a piston movable within the inner cylinder from a TDC position to a BDC position. The piston has a diameter of less than 1.7 inches. A stroke length of the piston is between the TDC position and the BDC position measuring greater than 3 inches. A driver blade is attached to the piston for movement therewith along a driving axis. A lifter is operable to move the piston and driver blade from the BDC position toward the TDC position. A drive unit is operably coupled to the lifter to provide torque thereto, causing the lifter to rotate. A source of pressurized gas is in fluid communication with the inner cylinder. A pressure of the pressurized gas acting on the piston at the TDC position is greater than 180 psi.

Abstract: An air compressor includes a compressor assembly with a motor and a pump driven by the motor, a battery receptacle, and a battery pack electrically connected to the motor via the battery receptacle for providing electrical power to the motor. The battery receptacle and the battery pack are positioned adjacent the compressor assembly. The compressor also includes a storage tank that receives compressed air from the pump, a case enshrouding the compressor assembly, an outlet port in fluid communication with the storage tank, and an adjustable pressure regulator at least partially positioned within the case. The outlet port configured to discharge compressed air from the storage tank at a regulated pressure determined by the pressure regulator. The compressor further includes an adjustment knob to adjust the regulated pressure of compressed air provided by the outlet port. The case attenuates noise emitted by the compressor assembly to less than 68 decibels.

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, a motor that provides torque to the rotary lifter to return the driven blade from the BDC position toward the TDC position, and a cam which, during operation of the rotary lifter, causes the rotary lifter to axially move along a rotational axis defined by the rotary lifter between a first position, in which the rotary lifter is engageable with the driver blade, and a second position, in which the rotary lifter is not engageable with the driver blade.

Abstract: A battery pack that is connectable to and supportable by a power tool (e.g., a hand-held power tool). The battery pack includes a top housing having a support member. The support member of the battery pack top housing is configured or operable to reinforce a support portion of the battery pack that is used to connect the battery pack to the power tool. By reinforcing the support portion of the battery pack, an interface between the battery pack and the power tool is able to withstand greater forces (e.g., from vibrations caused by the power tool).

Abstract: An expansion tool includes a housing, a motor supported by the housing and including a motor, a mandrel, and a drive mechanism configured to convert a rotational input from a motor shaft into translational movement of the mandrel. The expansion tool includes a first operating mode and a second operating mode. When the expansion tool is operated in the first operating mode, the drive mechanism is configured to reciprocate the mandrel between a retracted position and a first extended position. When the expansion tool is operated in the second operating mode, the drive mechanism is configured to reciprocate the mandrel between the retracted position and a second extended position different than the first extended position.

Abstract: A hand-held knockout punch driver includes a housing, a motor positioned within the housing, a head unit removably coupled to the housing, the head unit including a body, an input member movable relative to the body, and a draw rod to which at least one of a punch or a die is attachable. The draw rod is configured to move axially relative to the body in response to movement of the input member relative to the body. A quick-release mechanism removably couples the body to the housing and includes radially inward-extending locking members on one of the housing or the head unit and a plurality of radially outward-extending locking members on the other of the housing or the head unit engageable with the radially inward-extending locking members to lock the head unit to the housing.

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: An expansion tool includes a housing, a motor supported within the housing, a mandrel, and a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel. The drive mechanism includes a cam and a drive shaft coupled to the cam. The expansion tool further includes a frame including a hub and a neck extending from the hub and having an opening. A working element is coupled to the neck and has a plurality of jaws movable from a closed position toward an expanded position in response to movement of the mandrel from a retracted position toward an extended position. The mandrel extends through the opening to engage the jaws, and the drive shaft is rotatably supported by the hub.
