Abstract:
A powered tool constructed to axially drive a driver blade to impact and drive a fastener into a workpiece, said tool including a magazine configured for urging fasteners along an axis to be engaged by said driver blade, and comprising:a nosepiece assembly including a back plate and a front plate combining to define a path for the driver blade; said front plate being pivotally movable relative to said back plate between a closed position in which said front plate and said back plate are in contact with each other, and an open position in which said front plate is sufficiently displaceable from said back plate such that fasteners in said magazine are removable from said magazine generally along an axis defined by said magazine; said front plate being movable to an interim deflecting position between said closed position and said open position; a stop for retaining said front plate in said deflecting position and for preventing pivoting action of said front plate to said open position; disengagement means for disengaging said stop for enabling said front plate to reach said open position; and said disengagement means is a noncircular pivot bore on said front plate defining a first pivot axis enabling engagement of said stop, and a second pivot axis enabling disengagement of said stop.
