    Abstract: A powered nailer (10) includes a power source (12) including a driving element (16) reciprocating within a cylinder (14) between a pre firing position and a fastener driving position, the latter occurring when the driving element engages a bumper (20) disposed at the bottom (22) of the cylinder (14). A reciprocating valve element (40) defines a combustion chamber (30) in fluid communication with the cylinder (14), and is configured for receiving a dose of fuel and air prior to a user-generated ignition. A return chamber (52) at least partially surrounds the cylinder (14) and is in fluid communication with the cylinder (14), being configured for receiving a supply of pressurized air generated by the driving element (16) as it moves from the prefiring position to the fastener driving position, the pressurized air acting on an underside of the driving element (16) for returning it to the pre-firing position.

    Abstract: A combustion-powered fastener-driving tool includes a combustion-powered power source having a combustion chamber, a reciprocating piston and driver blade, and a valve sleeve reciprocable relative to the power source between a rest position and a firing position. The valve sleeve partially defines the combustion chamber. A lockout device is in fluid communication with the combustion power source and includes a reciprocating gas piston connected to a latch in operational proximity to the valve sleeve. The lockout device is configured such that upon combustion in the combustion chamber, gas from the combustion engages the gas piston and moves the latch to an engaged position in which the valve sleeve is prevented from moving to the rest position.

    Abstract: A fastener driving tool including a housing enclosing a cylinder having a lower end provided with a resilient bumper, a return air chamber in communication with the lower end of the cylinder and a piston dimensioned for reciprocation within the cylinder to impact the bumper at an end of the cylinder and having a driver blade depending therefrom for striking fasteners. At least one inlet opening is disposed in the cylinder and in communication with the return air chamber and at least one outlet opening is disposed in the cylinder and spaced from the at least one inlet opening. The at least outlet opening is in communication with the return air chamber and aligned with the piston so that each outlet opening is closed by the piston to seal the cylinder from air loss as the piston impacts the bumper and traps a residual volume of air in the sealed cylinder below the piston to damp impact of the piston upon the bumper.

    Abstract: Various embodiments of the present disclosure provide a combustion-powered fastener-driving tool including an engaging element that improves tool performance by frictionally engaging a piston upon its return to a pre-firing position, thereby reducing the likelihood that the piston will end up at a position other than the pre-firing position after completion of a fastener-driving cycle. In one embodiment, the fastener-driving tool comprises a cylinder, a driving assembly slidably disposed within the cylinder and movable from a pre-firing position to a firing position to drive a fastener into a workpiece, and an engaging element. The driving assembly includes an outwardly tapered engaging element contact surface, and the engaging element is positioned to engage the engaging element contact surface when the driving assembly is in the pre-firing position.

    Abstract: A combustion-powered fastener-driving tool (10) includes a combustion-powered power source (14) including a cylinder head (42) and a combustion chamber (18) defined by the cylinder head, a valve sleeve (36) and an upper surface of a reciprocating piston (22), the valve sleeve reciprocable relative to the cylinder head between a rest position and a pre- firing position. The valve sleeve (36) has a range of positions between a first sealing position in which the combustion chamber (18) is closed, and said pre-firing position in which the valve sleeve is prevented from further movement. A lockout device (60, 90, 100, 110) is associated with the power source and has an actuated position configured for preventing the reciprocation of the valve sleeve beyond the first sealed position to open the combustion chamber, but permitting movement of the valve sleeve from the first sealed position to the pre-firing position until the piston returns to a piston pre-firing position post combustion.
