ABSTRACT:
A magazine of a nailer gun organizes nails with the head of each nail in sliding contact with parallel support rails and the point of each nail on a support track that parallels the rails. The rails and track orient the nails so that they are parallel to each other and at an acute angle to the perpendicular between the rails and track. In this orientation the head of each nail overlaps the head of the nail preceding it and contacts the shaft of the nail following it. At a driver head of the gun, the distance between the point support track and the rails lengthens and the nails rotate for alignment with the axis of a chamber of the driver head. Upon reaching the chamber, each nail drops a short distance onto a dog and is retained in place by the dog. A driver of the gun impacts the nail in the chamber and drives it. The dog swings out of the way in response to the impact of the driver. A nail guide rotates and slides away from the chamber upon being engaged by a bent nail. Nails in a clip feed into the magazine through a gravity feed orientation passage that receives the nails from the clip one at a time and separates the received nail from the others so that the nail heads separate before introduction to the constraints of the rails and the point support track of the magazine.
