ABSTRACT:
A device for automatically presenting mandrel rivets to the nosepiece of a rivet installation tool, which receives rivets from a supply in a slidably mounted transfer arm while the arm is in a retracted position, and axially and radially moves the arm relative to the tool axis to a position of alignment with receiving jaws within the tool. The rivet is then propelled into the tool's nosepiece from the transfer arm by an air blast. The presentation device may be separately mounted within a rivet installation machine, or may be mounted to the tool body in a hand-held configuration. A first version provides successive, separately actuated axial and angular movements of the transfer arm, while a second version provides simultaneous axial and angular movement of the arm. The rivet is held within the transfer arm by a vacuum, which vacuum may be rapidly changed to a positive pressure on command to propel the rivet from the arm into the tool.
