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.

In a fastener-driving tool equipped with a fastener magazine, having a power source including a reciprocating driver blade for driving fasteners obtained from said magazine into a workpiece, and a reciprocating valve sleeve actuated by a cage, a nosepiece comprising:
- a nosepiece body configured for attachment at one end to said fastener tool and defining a fastener channel constructed and arranged for receiving said driver blade and said fasteners sequentially fed by said magazine, said fastener channel having a fastener outlet;
- and
- a unitary actuator reciprocating relative to said nosepiece body, having a first end contacting the workpiece, and a second end engaging said cage.
In a fastener-driving tool equipped with a fastener magazine, having a power source including a reciprocating driver blade for driving fasteners obtained from said magazine into a workpiece, and a reciprocating valve sleeve actuated by a cage, a nosepiece comprising:
- a nosepiece body configured for attachment at one end to said fastener tool and defining a fastener channel constructed and arranged for receiving said driver blade and the fasteners sequentially fed by said magazine, said fastener channel having a fastener outlet;
- and
- a unitary actuator reciprocally engaging said nosepiece body, and having a first end provided with a workpiece contact portion and a second end directly engaging the cage.
An actuator for use in a fastener-driving tool equipped with a fastener magazine, having a power source including a reciprocating driver blade for driving fasteners obtained from the magazine into a workpiece, a reciprocating valve sleeve actuated by a cage, and a nosepiece 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, said actuator comprising:
- a first end provided with a workpiece contact portion, defining a fastener outlet chamber of sufficient length for accommodating reciprocal movement of the nosepiece body relative to said chamber throughout a fastener driving cycle and a tab for receiving a magazine follower to disable tool operation when a limited number of the fasteners remain in the magazine;
- and
- a second end directly engaging the cage and defining a guide slot accommodating a guide member on the nosepiece body, said guide slot defining a reciprocating travel distance of said actuator relative to the nosepiece body, said travel distance corresponding to an amount of reciprocation associated with an entire fastener driving cycle.
