Abstract
A device for impacting a fastener in one embodiment includes a trigger. A trigger disabling mechanism changeable between a first condition wherein operation of the trigger is not disabled and a second condition wherein operation of the trigger is disabled is also included. The device includes a nose piece configured to change the trigger disabling mechanism from the second condition to the first condition. The nose piece includes including a first nose portion removably coupled to a second nose portion. The first nose portion and the second nose portion define a channel therebetween through which a fastener is driven.
Claims17
A device for impacting a fastener comprising:
- a trigger;
- a trigger disabling mechanism changeable between a first condition wherein operation of the trigger is not disabled and a second condition wherein operation of the trigger is disabled;
- a nose piece configured to change the trigger disabling mechanism from the second condition to the first condition, the nose piece including a first nose portion removably coupled to a second nose portion, the first nose portion and the second nose portion defining a channel therebetween through which a fastener is driven;
- a spreader defining a spreader angle;
- and
- a lever, the lever pivotably attached to the nose piece and movable between a first position whereat the angle formed between an arm portion of the lever and an upper surface of the first nose section is less than the spreader angle and a second position whereat the angle formed between the arm portion of the lever and the upper surface of the first nose section is equal to the spreader angle.

A device for impacting a fastener comprising:
- a trigger;
- a trigger disabling mechanism changeable between a first condition wherein operation of the trigger is not disabled and a second condition wherein operation of the trigger is disabled;
- and
- a nose piece configured to change the trigger disabling mechanism from the second condition to the first condition, the nose piece including a first nose portion removably coupled to a second nose portion, the first nose portion and the second nose portion defining a channel therebetween through which a fastener is driven, wherein:
- the first nose portion includes a first plurality of wedges opening toward a front portion of the first nose portion;
- and
- the second nose portion includes a second plurality of wedges opening toward a rear portion of the second nose portion.

A device for impacting a fastener comprising:
- a nose assembly including
- a base portion,
- a first nose section configured to be slidably positioned on the base portion, and
- a second nose section removably coupled to the first nose section to move with the first nose section along the base, the first nose section and the second nose section defining a path along which a fastener is driven by the device;
- a trigger mechanism for initiating a firing sequence;
- and
- a trigger disabling mechanism for disabling the trigger mechanism, the trigger disabling mechanism responsive to the position of the first nose section, such that when the first nose section is in a first position the trigger disabling mechanism disables the trigger mechanism and when the first nose section is in a second position the trigger disabling mechanism does not disable the trigger mechanism.

A method of impacting a fastener comprising:
- removably coupling a first nose section and a second nose section;
- forming an angle with an arm of a lever of the nose section and the upper surface of the first nose section;
- moving the coupled nose sections from a first extended position to a second depressed position whereat a first surface of a spreader of the nose section is in contact with the arm and a second surface of the spreader is in contact with the upper surface of the first nose section;
- enabling operation of a trigger when the coupled nose sections are in the second position;
- forcing a fastener along a channel formed by the coupled nose sections;
- forming a gap between opposing wedge walls of the first nose section and the second nose section;
- and
- rotating a spreading wedge of the lever into the gap.
