    Abstract: Rivets are delivered from a feed chute to a transfer location and blown through a feed tube to a loading device. The presence of a rivet is sensed both at the transfer location and at the loading device and a fault indicator is operated in the event a rivet sensed and transported from the transfer location does not wind up in the loading device. The operator hits the reset button which blows clean air thru the feed tube in an attempt to free the jammed rivet. In the event this does not occur, the system assumes the operator cleared the jam and loads the next rivet into position to be transferred and continues the cycle.

    Abstract: An automatic riveting machine is disclosed which counts the rivets, as set, to control the feeding of rivets from a feeder to the rivet track or chute. The track will be resupplied after a selected number of rivets are set or sooner should the track become prematurely empty by removal of rivets from the track.

    Abstract: Automatic riveting machine wherein spent mandrels generated by the setting of rivets pass through a collection tube en route to a collection box, having first means for sensing tool operation, second means for sensing entry of spent mandrel into collection tube, third means for sensing departure of spent mandrel from collection tube and means for determining from operation of said first means and of said second means and non-operation of said third means that a spent mandrel is blocked in collection tube and operating identification means to indicate said blockage.
