Abstract
In a fastener driving apparatus including a nose piece assembly defining an elongated drive track receiving a fastener driving element therein movable through an operating cycle including a drive stroke and return stroke, and a fastener feeding track communicating laterally with the drive track, an improved mechanism for feeding fasteners from a fastener package into a position to be driven by the fastener driving element during the drive stroke thereof is provided. The feeding mechanism includes an actuating mechanism mounted for movement through an operating cycle including (1) an operative stroke in a direction along the fastener feeding track toward the drive track for feeding fasteners to the drive track and (2) a return stroke. A fastener holding mechanism is also provided and is operatively coupled to the actuating mechanism for movement therewith through the operating cycle thereof, whereby during the operative stroke of the actuating mechanism the fastener holding mechanism holds the fasteners in position biased toward the drive track during at least a portion of the drive stroke so that a leading fastener from the fastener package is disposed in the drive track in positio…
