ABSTRACT:
An improved nailing machine including a reciprocatable plunger for sequentially severing and driving nails from a nailing strip, and a reciprocatable piston for advancing and retracting the plunger. The machine includes a unique reciprocatable control valve actuating and nail guide means which serves both to set a control trigger for activating the reciprocatable plunger, and to properly align a nail with a workpiece as the nail is driven into the workpiece, while at the same time maintaining the nailing strip in a fixed position to prevent contact between the driven nail and the next nail to be severed from the nailing strip. The machine further includes a magazine having retractable nailing strip advancing means which positively moves a nailing strip along the runway of the magazine, and which, in its retracted position, enables a nailing strip to be easily and readily inserted into or removed from the magazine of the machine.
