Fastener driving device particularly suited for use as a roofing nailer

Abstract

A housing including a handle portion and drive portion is provided. A power operated drive in the housing drive portion is operable to be selectively moved through a drive stroke and a return stroke. A nosepiece and magazine assembly are carried by the housing including cooperating fixed and movable structure defining an elongated drive track, a feed track leading laterally into the drive track, and a coil container leading into the feed track. A fastener driving element is slidably mounted in the drive track and operatively connected with the power operated drive so as to drive a leading fastener fed into the drive track from the feed track outwardly of the drive track. The unitary movable structure is mounted for pivotal movement when a fastener package has been depleted from a closed operating position in cooperating relation with the fixed structure into an open loading position. An actuating mechanism is provided for actuating the power operated drive to move through an operating cycle. An actuation prevention mechanism is provided for preventing the actuation of the power operated drive by the actuating mechanism in response to the movement of the movable structure from the closed operating position to the open loading position. A resilient guard structure is disposed on the housing and extends outwardly from the periphery thereof. Mechanical structure is provided for fixedly mounting the resilient guard structure on the housing.
