ABSTRACT:
SPECIFICATION
BACKGROUND OF THE INVENTION
1. Field of the Invention
An attachment for feeding tin tags from a cartridge to a nailing gun is disclosed, including means for radially expanding the longitudinally-split cartridge wall to release the stack of cartridges contained therein, whereby successive tin tags may be fed from the bottom of the stack from the tin tag dispensing station to the nailing station.
2. Brief Description of the Prior Art
Tin tag dispensing attachments for nailing guns are well known in the patented prior art, as evidenced by the earlier McGuinness U.S. pat. Nos. 5,634,583 and 5,791,546. In these prior tin tag dispensing systems, the attachment systems serve to automatically displace successive tin tags from the bottom of a stack to a nailing station relative to the nailing gun to which the devices are attached.
In the aforementioned McGuinness, et al., U.S. pat. No. 5,791,546, the use of tin tag cartridge means has been proposed for supplying the tin tags to the attachment.
The present invention was developed to provide an improved tin tag cartridge which is readily inserted into, and easily removed from, the working chamber of the tin tag dispensing housing that is attached to the gun. The invention provides an inexpensive and positive way for supplying a stack of tin tags to the loading station of the attachment.
SUMMARY OF THE INVENTION
Accordingly, a primary object of the present invention is to provide a nailing gun attachment having a housing containing a dispensing chamber for receiving a tin tag cartridge including a resilient longitudinally split cartridge wall within which is supported a stack of tin tags, expansion means being provided on the housing for radially expanding the bottom portion of the cartridge wall, thereby to release the stack of tin tags contained therein.
According to a more specific object of the invention, the expansion means comprises an annular upwardly directed pointed edge having an internal diameter which is greater than the diameter of the tin tags, but less than the inner diameter of the tubular cartridge wall. Spring biasing means bias the cartridge longitudinally downwardly toward the pointed edge, thereby to expand the cartridge wall radially outwardly to release the stack of tin tags supported therein.
A further object of the invention is to provide a sectional housing including a cover section that is outwardly pivotable toward an open loading position at which a cartridge carrying a stack of tin tags may be loaded thereon. After the cover means is returned to the closed position and thereby introduce the tin tag cartridge into the housing chamber, latching means are operable to lock the cover section in the closed position. Spring means initially bias the cartridge and tin tag stack downwardly forward the cartridge wall expansion means, and following expansion of the cartridge, subsequently bias the stack downwardly relative to the cartridge wall toward the tin tag loading station arranged therebelow.
