Abstract
A fastener-driving tool has a housing including a combustion chamber, where the combustion chamber generates combustion for driving a fastener, and a processor associated with the housing and in communication with the combustion chamber. The processor is configured to cause an initial combustion in the combustion chamber and cause a fastener to be driven when a first actuation event and a second actuation event occur, and is configured to cause at least one subsequent combustion in the combustion chamber and cause at least one additional fastener to be driven when only the first actuation event occurs.
Claims18
A fastener-driving tool comprising:
- a housing including a combustion chamber;
- and
- a processor associated with said housing and in communication with said combustion chamber,
- said processor configured to cause an initial combustion in said combustion chamber and cause a fastener to be driven when a first actuation event and a second actuation event occur, and
- said processor configured to cause at least one subsequent combustion in said combustion chamber and cause at least one additional fastener to be driven when only said first actuation event occurs.
A fastener-driving tool including a trigger control mechanism operable in a sequential actuation mode and a contact actuation mode, said tool comprising:
- a housing;
- a workpiece contact element movably connected to said housing, said workpiece contact element being movable between a rest position and an activated position;
- a trigger movably connected to said housing;
- an actuation lever movably connected to said trigger;
- a trigger assembly including a stem, said stem being movable between a rest position and an activated position;
- and
- a processor associated with said housing,
- wherein said processor is configured to cause the tool to operate in the sequential actuation mode to cause a fastener to be driven into a first location on the workpiece when said workpiece contact element is pressed against the workpiece thereby moving said workpiece contact element to said activated position, and said trigger is moved to a pressed position causing said actuation lever to move said stem to said activated position;
- and
- wherein said processor is configured to cause the tool to operate in the contact actuation mode to drive at least one additional fastener into a second location on the workpiece when said trigger is held in said pressed position and said workpiece contact element is pressed against the workpiece causing said actuation lever to contact and move said stem to said activated position.
A fastener-driving tool comprising:
- a housing;
- a combustion chamber in said housing;
- a workpiece contact element movably connected to said housing and movable between a rest position and an activated position;
- a trigger movably connected to said housing;
- and
- an actuation lever movably connected to said trigger;
- wherein in a sequential actuation mode, combustion is generated in said combustion chamber to drive a fastener into a workpiece each time said workpiece contact element and said trigger are each moved from said rest position to said activated position in a designated sequence, and
- wherein in a contact actuation mode, said trigger remains in said activated position and combustion is generated in said combustion chamber to drive at least one additional fastener into the workpiece each time said workpiece contact element is moved to an activated position by depressing said workpiece contact element on the workpiece.
