  • Patent number: 6431427
    Abstract: A nailing device for a coiled nail belt is provided. The nailing device includes an upper part that resembles a hammer handle at the end and has a miter gage at an opposite end. The upper part also includes an arm component having a magazine, a hammerhead and a nail feed. The hammerhead includes a drive hole in which a striker set on a bearing bolt in the miter gage may be guided. The nailing device further includes a rocker arm which is coupled to a shaft in the hammerhead and which, upon activation of the nailing device, displaces a feeder in an opening in the hammerhead, moves the shaft and extends through an opening in the rocker arm. The area between the border of the opening and the shaft is filled with rubber filler.
