ABSTRACT:
A blind rivet feeding attachment for an automatic riveting machine having a riveting head and a drill mounted on a reciprocating shuttle comprises a rotating transfer arm for picking up a rivet from a supply tube and inserting it in the riveting head of the automatic riveting machine. While the riveting head is drilling a hole in the workpiece at a "work" position, a rivet clamp extracts a new rivet from the supply tube and retains it at the "pickup" position. After the drill has formed the hole, the shuttle moves the riveting head to the work position and installs a rivet in the hole. Rack and pinion gearing rotates the transfer arm towards the rivet clamp in response to the shuttle motion and engages the new rivet tangentially. After the riveting head has installed the rivet, the shuttle moves the riveting head to a "delivery" position, where the transfer arm inserts the new rivet into the riveting head. The gearing rotates the transfer arm back to the pickup position in response to the shuttle motion to pick up the next rivet, which is retained in the rivet clamp. A rivet stem ejector removes the broken-off rivet stem from the head before inserting the new rivet.
