Abstract
A rivet driver for easily fastening a rivet comprising a male shank and a female tube to separate members has a construction such that the separate members may be united by hydraulically driving the male shank into the female tube to thereby cause the female tube to be radially expanded outwardly and that upon completion of this hydraulic driving, it feeds a subsequent rivet to the supply position and is ready for next driving of the male shank into the female tube of the subsequent rivet.
