ABSTRACT:
A hydraulic rivet tool having a pair of opposing supports on a frame one of which holds an anvil and the other supporting a hydraulic cylinder. A hollow sleeve is extensible from the cylinder and carries a guide to clamp the workpiece. Contained within the sleeve for relative movement therewith is a dual purpose piston carrying a rivet engaging member. A spring is interconnected between the sleeve and the piston to restrict their relative motion until the sleeve guide has clamped the workpiece. Hydraulic fluid under pressure delivered to the cylinder first causes the piston and sleeve to extend from the hydraulic cylinder and causes the sleeve to clamp the workpiece. The piston then, overcoming the spring restricting the relative motion between it and the sleeve, continues its movement to perform work on the rivet.
