Various embodiments of the present disclosure provide a combustion-powered fastener-driving tool including multiple combustion chambers and/or usable with fuel canisters of varying lengths.

Fastener-driving tool with multiple combustion chambers and usable with fuel canisters of varying lengths

A fastener-driving tool including a housing, a driving device associated with the housing and including a driver blade, a biasing member and a coupler attached to the driver blade and the biasing member, and a compound gear rotatably attached to the housing and in engagement with the coupler, where the compound gear is configured to rotate between a first position and a second position. The compound gear is rotated to the first position to move and secure the biasing member in a biased position when the driver blade is in a pre-drive position, and upon actuation, the biasing member is released from the biased position and biases the compound gear to move to the second position thereby causing the driver blade to move to a driven position for driving a fastener.

Fastener-driving tool including a driving device

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

High efficiency engine for combustion nailer

A stud miss indicator system for a fastener driving tool includes at least one sensor generating at least one signal based on forces generated by a fastener driving operation, a software program configured for receiving the at least one signal, for evaluating the at least one signal as to a fastener being either improperly driven or properly driven, and the program generating at least one appropriate output signal reflective of the evaluation.

Stud miss indicator for fastener driving tool

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.

Portable pressurized power source for fastener driving tool

A fuel delivery system for use with a combustion fastener driver including a cylinder head frame, the 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 a tool fuel cell chamber. The adapter includes a collar configured for receiving the valve stem and being suspended for restricted vertical movement relative to the flange. 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 a combustion chamber.

Interface for fuel delivery system for combustion fastener driver

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.

Interface for fuel delivery system for combustion nailer

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.

Fastener advance delay for fastener driving tool

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 delay mechanism operatively associated with the magazine and configured for engaging a second fastener and delaying advancement of the subsequent fastener to the nosepiece until the driver blade returns to the pre-firing position after driving a leading fastener.

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.

Single switched dual firing condition combustion nailer

A fastener for driving into a substrate has a head having an upper surface and a lower surface, a penetrating tip and a shank extending from the lower surface of the head to the penetrating tip. At least one deformable feature is formed on the head. The deformable feature is configured to absorb energy and to deform. When a driving element is driven onto the head to drive the fastener into the substrate, the deformable feature absorbs energy and is deformed as the head contacts the substrate.
