  • Patent number: 7500588
    Abstract: An improved tin tag dispensing and nailing tool includes an operating member that is adapted for connection with a roofer's nailing gun, which operating member is guided by a pair of spaced vertical guide rods for vertical sliding displacement relative to the tool housing between an upper retracted position and a lower nailing position. The operating member is formed from a synthetic plastic material and contains vertical though bores that respectively receive the guide rods. Tubular oil-impregnated bushings are mounted in the through bores concentrically about the guide rods. A linkage arrangement connects the operating member with a shuttle plate that is displaced between a loading position adjacent the tin tag supply station and a discharging position adjacent the tin tag nailing station. An integral punched-out tongue portion extends upwardly at an acute angle from the shuttle plate for engagement with the lowermost tin tag of a stack.
