Abstract
An automatic tool for rapidly setting rivets or like fasteners of the expansion type supplied in strip form. It comprises a magazine for receiving a strip of rivets in which the rivets can advance stepwise so that the leading rivet faces the outlet orifice. A breech movable longitudinally along the axis of the outlet orifice and provided with a barrel fitting over the rivet mandrel and over the rivet head so that the rivet is fetched into a setting position, well clear of the magazine, in order to enable same to be set visually. A striker sliding along the axis of the breech is provided with a pin which strikes the mandrel of the rivet through the barrel and drives it into the body of the rivet and causes the rivet to be secured in the assembly holes. A double-acting detent and trigger actuating mechanism is so devised that an initial phase of operation of the detent causes the breech to advance while a second phase of operation of the detent causes the striker to act.
