Abstract
A vibration damped hand held rivet bucking tool having a vibration exposed inertia member (10) provided at a forward end with a rivet engaging implement and a handle (12) insulated from the inertia member (10) by means of two pretensioned coil-type springs (15, 16) which have different diameters and which are located with the small diameter spring (16) inside the large diameter spring (15). A sleeve element (17) connected to the inertia member (10) is located between the springs (15, 16), and a central rod (18) connected to the handle (12) extends into the small diameter spring (16). The large diameter spring (15) acts between a shoulder (23) on the sleeve element (17) and the handle (12), respectively, whereas the small diameter spring (16) acts between an inner shoulder (24) on the sleeve element (17) and an outer shoulder (26) on the central rod (18). A central bore (20) in the inertia member (10 ) accommodates the springs (15, 16) and the sleeve element (17).
