ABSTRACT:
A device for receiving rivets from a rivet delivery tube of a pneumatic supply system, slowing the rivet velocity, and holding the rivet in a staged position until it is ready to be fed into a hole in a workpiece, includes a perforated tube having a connection to the rivet delivery tube. The interior diameters of the rivet brake and staging tube and the rivet delivery tube are equal so the rivet sees no edges or shoulders when passing through the delivery tube into the staging tube. The rivet brake and staging tube has a flange by which it is connected to the side of a shuttle carrier which carries a shuttle body in which is mounted a slotted rivet guide shoe. The rivet guide shoe has an arm that is positioned in front of the end of the rivet brake and staging tube when the shuttle is in its drilling position, so the rivet may be sent while the rivet hole is being drilled, and the rivet is held at the end of the rivet brake and staging tube, ready for insertion into the hole. The shuttle body can be moved to position a curved, arched slot in the rivet guide shoe in line with the end of the rivet brake and staging tube, whereupon the rivet is blown from the end of the rivet brake and staging tube, around the slot in the rivet guide tube, through a rivet guide tube, and into the hole in the workpiece.
