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.

A nailing gun attachment for supplying successive tin tags to a nailing station adjacent an associated nailing gun, comprising:

(a) housing means including a horizontal base portion containing a vertical opening defining a nailing station, said base including a supply station spaced horizontally from said nailing station, said housing including a vertical hollow body portion extending upwardly from said base portion;
(b) cartridge support means connected with said housing body portion for supporting a cartridge containing a vertical stack of tin tags above said supply station;
(c) shuttle means connected with said base portion for movement between a loading position adjacent said supply station and a discharge position adjacent said nailing station, said shuttle means being operable to displace the lowermost tin tag from said stack toward said nailing station;
and
(d) operating means for displacing said shuttle means between said loading position and said discharging position, said actuating means including:
(1) an operating member adapted for connection with the nailing gun;
(2) guide means guiding said operating member for vertical sliding displacement relative to said housing between an upper retracted position remote from said housing base portion, and a lower nailing position adjacent said base, said guide means including:
(a) a pair of vertical laterally-spaced guide rods formed of metal, said guiding rods slidably extending through a pair of vertical through bores contained in said operating member;
(b) first fastening means fastening the lower ends of said guide rods to said housing base portion;
and
(c) second fastening means fastening the upper ends of said guide rods to said housing body portion;
(3) linkage means connecting said operating member with said shuttle means to case said shuttle means to be in said loading position and said discharging position when said operating member is in said lower and upper positions, respectively;
and
(4) spring means biasing said operating member toward said upper position.
