Single tool nailing bridge system

A nailing bridge system for mounting a nail gun, comprising:

• a longitudinally extending support surface;
• a pair of transversely spaced tracks extending along said longitudinally extending support surface;
• first and second framework members, respectively disposed upon said pair of transversely spaced tracks for longitudinal movement along said pair of transversely spaced tracks, and comprising a first support beam which extends transversely between said first and second framework members and is disposed above an underlying structure into which nails are to be driven in order to secure articles to the underlying structure;
• a carriage assembly movably mounted upon said first support beam for movement along said first support beam in a transverse direction so as to be disposed at any one of a plurality of positions along a transverse locus along which nails are to be driven into the underlying structure;
• a nailing gun mounted upon said carriage assembly for inserting nails into the underlying structure as said carriage assembly is moved along said first support beam in said transverse direction;
• wherein said nailing gun is pivotally mounted upon said carriage assembly within a longitudinally extending plane and around a transversely oriented pivotal axis which is disposed parallel to said first transversely extending support beam such that said nailing gun can achieve various different firing modes with respect to the underlying structure;
• said nailing gun is pivotally mounted upon an inner carriage frame assembly;
• a pair of arcuate-shaped mounting brackets are fixedly mounted upon an outer carriage frame assembly;
• a plurality of roller mechanisms interconnect said inner carriage frame assembly to said pair of arcuate-shaped mounting brackets;
• and
• a pair of piston-cylinder assemblies, comprising first and second piston rods, interconnect said outer carriage frame assembly to said inner carriage frame assembly so as to cause said inner carriage frame assembly, and said nailing gun, to be movable with respect to said outer carriage frame assembly.
