Abstract: In a fastener-driving tool equipped with a fastener magazine, and a power source including a reciprocating driver blade for driving fasteners obtained from the magazine into a workpiece, and a reciprocating valve sleeve actuated by a cage, a nosepiece is provided, including a nosepiece body configured for attachment at one end to the fastener tool and defining a fastener channel constructed and arranged for receiving the driver blade and the fasteners sequentially fed by the magazine, the fastener channel having a fastener outlet. A unitary actuator reciprocates relative to the nosepiece body, has a first end contacting the workpiece, and a second end engaging the cage.

A tubular pin guide is disposed for reciprocal movement in the fastener channel for receiving fasteners traveling toward the outlet. A unitary actuator has a first end engaging the pin guide for common reciprocation relative to the nosepiece body and a second end engaging the cage.

Abstract: A nozzle for dispensing sealant is provided. The nozzle includes, but is not limited to, a body section and a coupling member. The body section forms a primary channel through which sealant is dispensed. The primary channel forming an entrance through which sealant enters the body section and an exit through which sealant is dispensed from the nozzle. The coupling member is at the entrance of the primary channel and has a first fastener configured to mate with a second fastener of the sealant container.

Abstract: A nozzle head for dispensing sealant within a gap is provided. The nozzle head includes, but is not limited to, a body section and a port connected with the body section. The body section forms a primary channel through which sealant is dispensed. The primary channel forms an entrance through which sealant enters the body section and an exit through which sealant is dispensed from the nozzle. The port is connected with the body section and surrounds the exit. The port forms a chamber having a tip portion opposed to a rear opening. The chamber forms an angled path from the tip portion to the rear opening to trap and guide excess sealant within the chamber to the rear opening.
