Abstract
Abstract A noise inhibitor for a rivet gun is disclosed comprising a hollow flexible elastic coupling sleeve having one end stretchably fitted over a portion of the gun casing, a concial transparent body tube is received in the other end of the coupling sleeve and a cushion member in the form of a soft rubber tube is fitted over the opposite end of the conical body tube to engage the work being riveted with the impact member of the rivet gun being positioned in the transparent body tube so as to be visible by the user; in another embodiment, the conical body tube and rubber sleeve members are oblong conical configuration and are dimensioned to fit over a rivet bucking bar having an impact surface visible through the transparent body tube so that in both embodiments the working surface is visible; however, noise emanating from the working surface components is substantially dissipated.
