A nail and dimpler driving apparatus for a nailing gun is provided having a barrel with a short hardened metal dimpler which slides longitudinally in the end of the barrel and comprises a hardened metal piston having a broadened face at its end extending symmetrically on opposite sides of a metal plunger which extends longitudinally from the lower center of the piston face in alignment with an orifice through the dimpler. The piston reciprocates to impact a shoulder at the inner end of the dimpler. The barrel has a longitudinal rail extending along the top of its bore to maintain the piston and dimpler in angular alignment and to guide nails fed into the bore from an opening located in the side of the barrel between the tip of the retracted plunger and the dimpler shoulder. The rail has a longitudinal groove in its lower edge to aid in guiding the nails and in providing clearance for the residue of web material used to join the nails in flexible collated strips.

A nailing gun having a housing, a barrel rigidly fixed to and extending longitudinally from said housing and having a fastener delivering orifice at the end thereof, a magazine for maintaining a supply of fasteners and connected to said barrel, means for feeding a fastener from said magazine into said barrel, a plunger moveable longitudinally in said barrel for driving said fastener from said barrel through said orifice, means carried by said housing for reciprocating said plunger in said barrel, and a fastener driving and dimpling apparatus comprising: a dimpler mounted at the end of said barrel longitudinally moveable therein and having said orifice formed therethrough, a piston drivably connected at one end to said plunger reciprocating means and extending longitudinally from said housing and into and longitudinally moveable in said barrel, said plunger being fixed to and extending longitudinally from the other end of said piston in alignment with said orifice, a rail fixed to and extending longitudinally along the inside of said barrel at one side thereof and having a fastener guiding edge in longitudinal alignment with a side of said orifice, and said piston having a longitudinal channel along one side thereof, said channel having a cross section conforming to the dimensions of said rail and slidably fitted therearound.
