The Hand-Held Single Impact Rivet Gun and Method of Back Riveting was invented by Joel J. Heck (Mulvane, KS), Mark W. Palmer (Peru, KS), Earl V. Long (Wichita, KS), Richard Gonzalez (Wichita, KS) on the 23rd of November, 2004, and bearing patent number US6820319B2.
The rivet gun of the present invention is a hand-held pneumatic gun which back drives the rivets against a solid tooling surface having an identical shape of the aircraft section being fabricated. This process replaces the hand-held bucking bar for each rivet with a stationary tooling surface which provides a backing bar for all of the rivets within the section being fabricated. The principal object of the present invention is to provide a single person riveting method which utilizes a single impact rivet gun for back riveting against a fixed tooling surface. A further object of the present invention is to provide a rivet gun having an offset driving hammer for reaching under the flange of a C-channel. Another object of the present is to provide a single piece of stationary back bar tooling for backing all of the rivets in a section of aircraft being constructed.
