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.
Claims8
A blind riveting tool of the type including a reusable mandrel carrying a plurality of rivets to be successively set thereby, the tool comprising an elongated barrel, abutment members movably mounted on the barrel and closeable to engage a rivet head during rivet setting, means engageable with the stem of the mandrel to pull it in the setting operation, means for advancing the rivets along a stem of the mandrel to position the leading rivet beyond the abutment members, and means 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.
A blind riveting tool comprising a housing which includes an elongated barrel, abutment members mounted on a front end portion of the barrel for movement between closed and open conditions and engageable in closed condition with a rivet head in a rivet-setting operation, a mandrel with a stem adapted to carry a plurality of rivets thereon, means for engaging the mandrel stem to pull it in a rivet-setting operation, a sleeve extending axially in the barrel and surrounding the rivets on the stem, and means for causing air to flow through the sleeve to advance the rivets along the stem to urge a leading one of the rivets beyond the abutment members.
