Abstract
A rivet delivery device is provided for transferring a rivet from a rivet passage to a nose piece of a pulling head and jaw case mechanism. The rivet delivery device is air driven to extend forwardly of the rivet setting tool and rotates to present a rivet in front of the jaws and then transfers the rivet into the jaws. The angular rotation and stroke length of the rivet delivery device can be easily adjusted. A double-acting piston is driven in both directions by positive air pressure to extend and rotate the delivery device in front of the nose piece and returning the rivet delivery device after rivet transfer. The use of a double-acting piston greatly enhances the speed at which the, rivet delivery device can operate.
