ABSTRACT:
In a hydraulic riveter wherein an extension on a piston carries a jaw holder containing an annular array of gripping segments with conical outer surfaces slidable on a conical inner surface of the holder, a second piston is slidable in a bore and is operative to force the segments along the wedging surface to grip a rivet. A fluid passageway brings the bore into communication with the cylinder, so that as pressure builds up in the cylinder to increase pulling force, the second piston is forced against the gripping segments with increasing force to build up clamping force on the rivet in direct relation to the pulling force of the tool.
