Abstract: A roofing gun attachment for dispensing tin tags includes a base, a supply chamber mounted on the base which receives a cartridge containing a plurality of stacked planar tin tags, a shuttle slidably disposed within the base for individually displacing the tin tags from a feeding station located below the supply chamber to a nailing station where the tin tag is pierced by a nail discharged from a nailing gun, and a pair of cam arms each connected with a slide member for moving the shuttle between the feeding station and the nailing station when the nailing gun is pressed against a nailing surface and lifted therefrom. The supply chamber includes an access door which allows the tin tag cartridge to be easily replaced and further includes a manually-actuated spring-loaded plunger which biases the tin tags toward the feeding station.

Abstract: A tin tag dispensing apparatus for a nailing gun includes a support member having a tin tag dispensing groove, a shuttle slidably disposed within the support member, a tube receptacle containing a plurality of stacked tin tags, a slide member slidably mounted on the tube receptacle, a linkage assembly connecting the slide member with the shuttle, and a mounting plate for connecting the apparatus to the nailing gun. When the gun is lifted, the slide member slides upward along the tube receptacle and causes the shuttle, through the linkage, to engage and displace a single tin tag resting in the tin tag dispensing groove to a nailing station where it is retained until pierced by a fastener discharged from the nail gun.
