Abstract: A nailer includes a power source including a piston reciprocating within a cylinder; a driver blade secured to the piston for common movement relative to a nosepiece; a magazine connected to the nosepiece for feeding fasteners sequentially for being driven into a workpiece by the driver blade; a fastener delay mechanism operatively associated with the magazine and configured for engaging a subsequent fastener and delaying advancement of the second fastener to the nosepiece until the driver blade returns to the pre-firing position after driving a leading fastener; and wherein the delay mechanism includes an electromagnetic solenoid with a reciprocating plunger connected to a pivoting cam member such that extension of the plunger causes the pivoting cam member to pivot into a blocking position between the fasteners.

Abstract: A pressurized fluid container for use with a fastener-driving tool, the container having an outer shell defining an inner chamber, having an open neck and an effective height, a closure sealingly engaged on the open neck, and a tube depending from the closure.

Abstract: A fastener driver tool powered by a pressurized power source having a supply of compressed fluid includes a magazine associated with the tool for storing and supplying fasteners to a tool nose. A cylinder in the tool has a reciprocating piston associated with a driver blade sequentially engaging fasteners from the magazine as they are fed into tool nose. A control system is configured for directly electrically controlling a flow of compressed fluid for driving the piston.

Abstract: A combustion tool is provided, including an engine with a ratio of cylinder volume to combustion chamber volume of at least 1.1.

Abstract: A combustion tool is provided, including a combustion power source with a reciprocating valve sleeve moving between a rest position in which a combustion chamber is open, and a closed position in which the combustion chamber is sealed, a control system operatively connected to the power source, and a trigger switch connected to the control system and providing operator interface with the control system. The control system is configured such that operator manipulation of the trigger switch is the only operator initiated movement required for initiating repetitive spark generation.

Abstract: A fuel delivery system for use with a combustion nailer including a cylinder head frame, the delivery system includes a fuel cell with an outer shell having a closed lower end and an open upper end, a closure crimped over the upper end and defining an opening for accommodating a reciprocating valve stem, a fuel cell adapter frictionally engaging the closure and including a flange configured for suspending the fuel cell in the fuel cell chamber. A stem receiver block is connectable to the cylinder head frame and includes a stem engagement portion configured for directly and sealingly engaging an end of the valve stem, the stem engagement portion being in fluid communication with an internal receiver passage constructed and arranged for delivering fuel to the combustion chamber.

Abstract: A fastener driving tool is disclosed having a self contained pre-pressurized pneumatic power source. Operator actuation of a trigger mechanism causes a pressurized medium supplied by the self contained pre-pressurized power source to flow through a valve and to propel a piston connected to a driver blade towards a nosepiece assembly end of the tool. The flow of the pressurized medium through the valve further recoils a spring-biased activating bolt which resets the trigger mechanism.

Abstract: A powered tool constructed to drive a fastener into a workpiece includes a nosepiece assembly including a back plate and a front plate combining to define a path for a driver blade, the front plate being pivotally movable relative to the back plate between a closed position, in which the front plate and the back plate are in contact with each other, and an open position. The front plate is movable to an interim deflecting position between the closed position and the open position. A handle portion has an outer surface at least partially defining a grip, and an inner surface at least partially defining a chamber. The handle portion includes a substrate having at least one aperture, and an overmold configured for forming a gripping surface on the outer surface and for extending through the apertures into the chamber for forming a resilient mounting point.
