A fastener driving device includes a housing assembly, a nose assembly connected to the housing assembly, a magazine for carrying a supply of fasteners through a feed channel along a feed direction toward the nose assembly, and a plurality of stop pawls independently movable about a common pivot axis. Each stop pawl has a distal end extending into the feed channel.

Fastener driving device with mechanisms to limit movement of nails

A fastener driving device includes a nose assembly having a drive channel, a magazine for carrying a supply of fasteners through a feed channel along a feed channel direction toward the nose assembly, and one or more mechanisms for preventing undesirable movement of fasteners. The mechanisms may include a first stop pawl and a second stop pawl for preventing the supply of fasteners from moving along a direction opposite to the feed channel direction. The stop pawls may extend from a common side of the feed channel and pivot on a common axis. The mechanisms may also include a first nail stop, a second nail stop and/or a movable nail stop.

A fastener driving device includes a nose assembly carried by a housing that has a reservoir. The nose assembly has a fastener drive track. At least a portion of the fastener drive track is defined by a movable portion of the nose assembly. A fastener driver is movably mounted in the housing and configured to enter the drive track and drive successive leading fasteners into a workpiece. A head valve is constructed and arranged to be actuated so as to allow the pressurized gas to move the fastener driver through an operating cycle. An actuator is constructed and arranged to actuate the head valve. The actuator includes a trigger valve constructed and arranged to allow passage of the pressurized gas from the reservoir to a chamber above the head valve, and a contact valve operatively connected to the movable portion of the nose assembly.
