ABSTRACT:
A blind riveting tool of the type including a reuseable mandrel carrying a plurality of rivets to be successively set thereby. The rivets are advanced along the mandrel by causing air to flow through a sleeve to urge a leading one of the rivets beyond abutment members at the end of the tool. A catch having a finger is provided for urging the next to leading rivet and those behind it rearwardly so that the abutment members can close to embrace the mandrel behind the leading rivet without interference from the next one. The arrangement also facilitates reloading of the tool with another or the same reuseable mandrel when a new group of rivets is to be installed.
