Abstract
The disclosure is of a mechanical riveter wherein rivet-gripping jaws are pulled through a slideway by means of a pull rod. Each of a pair of links is pivoted between one of a pair of squeezable handles and a yoke carried on the pull rod. Means are provided to adjust the position of the yoke along the rod, thus fixing the length of the stroke and the mechanical advantage of the tool.
