Abstract: A powered fastener driver includes a magazine in which fasteners of a first length or fasteners of a second length greater than the first length are receivable. The magazine includes a shear block, a loading portion, and a feed channel extending lengthwise through the magazine between the shear block and the loading portion. The loading portion includes a first slot and a second slot that are each configured to receive fasteners of the corresponding first and second lengths for entry into the feed channel. The loading portion also includes a pivot member configured to prevent fasteners of the first length from being loaded into the second slot corresponding to the fasteners of the second length. The pivot member is pivotable about a pivot axis between a first, blocking position blocking access to the second slot, and a second, bypass position permitting access to the second 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 rotary lifter having a body and a drive pin coupled to the body. A roller is rotatably coupled to the drive pin and includes a non-cylindrical outer peripheral surface defining a plurality of engagement sections. A tooth of the driver blade is configured to engage one of the engagement sections when moving the driver blade from the bottom-dead-center position toward the top-dead-center position.

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 kickout arrangement is at least partially defined by an outer surface on one of a torque output member and a torque input member and an aperture formed in the other of the torque output member and the torque input member in which the outer surface is received. The kickout arrangement configured to permit limited rotation of the torque output member relative to the torque input member between a first position and a second position.

Abstract: A fastener driver includes a pusher assembly slidably coupled to a magazine assembly. The pusher assembly includes a first portion and a second portion that are selectively movable relative to each other. The pusher assembly is adjustable between a first state in which the first portion and the second portion are configured to move together in unison toward the channel, and a second state in which the first portion moves relative to the second portion toward the channel. A dry-fire lockout assembly includes a blocking member coupled to the magazine assembly or the nosepiece assembly, and a lockout member selectively engageable with the blocking member for moving the blocking member from a first position and a second position. The pusher assembly is configured to transition from the first state to the second state after a predetermined number of fasteners remain in the magazine assembly.

Abstract: A fastener driver includes a housing, a cylinder supported by the housing, and a moveable piston positioned within the cylinder. A driver blade is attached to the piston and movable therewith between a top-dead-center position and a driven or bottom-dead-center position. The driver blade includes a body having a first side and an opposite, second side with the driving axis passing therebetween, a plurality of teeth extending from the first side of the body, and a plurality of projections extending from the second side of the body. The body and the projections are bisected by a common plane. The teeth extend at an oblique angle from the first side of the body relative to the common plane.

Abstract: A powered fastener driver includes a housing, a cylinder within the housing, the cylinder containing a pressurized gas, a piston within the cylinder and movable from a top-dead-center position to a bottom-dead-center position, a driver blade movably coupled to the piston, a lifter, a drive unit configured to provide torque to the lifter, and a sensor. The driver blade has a plurality of teeth defining a predetermined number of edges. The sensor is configured to detect an edge of one or more of the plurality of teeth and a controller in communication with the drive unit and the sensor. The controller is configured to count a number of edges detected by the sensor, compare the number of detected edges to the predetermined number of edges, and stop the drive unit when the number of detected edges is less than the predetermined number of edges.
