Abstract
In a blind riveting machine, in which a mandrel having a head is pulled downwardly by reciprocable and openable pulling jaws to draw the mandrel head through the bore of a tubular rivet supported at a setting station by normally closed, openable nose jaws, the nose jaws have yieldable detent means for resisting upward movement of the mandrel, and a reciprocable tube concentric with the mandrel for lifting further rivets along the mandrel, past the opened pulling jaws and nose jaws, to the setting station, has a spring detent which becomes frictionally engaged with the mandrel whereby the mandrel after being lifted with the rivets can be pulled downwardly again so that its head abuts the rivet at the setting station, thereby accurately adjusting the position of the mandrel relative to the pulling jaws, before the pulling jaws again grip the mandrel, in dependence upon the actual size of the rivet next to be set.
