Abstract

The system accordingly strictly accounts for all rivets and prevents a rivet from being removed for any reason and not accounted for. This assures that no free rivet will find itself within the workpiece being riveted.

Claims

1. A blind rivet setting tool comprising

a nose into which a single blind rivet is fed for setting prior to delivery of the next rivet to the nose,

means for defining a riveting process during which a selected number of rivets will be sequentially set by the tool,

means for counting the number of rivets set by said rivet setting tool during the defined riveting process,

means for counting the number of rivets received by said nose during the defined riveting process,

means for comparing the count of said counting means following the completion of said defined riveting process with said selected number of rivets to be sequentially set during the riveting process defined by said defining means and,

means for alerting the operator whenever the defined riveting process is completed but the number of rivets supplied to the nose exceeds said selected number of rivets set during the defined riveting process

means for informing the operator whenever the defined riveting process is complete but the number of rivets actually set is less than the number of rivets to be set during the defined riveting process.

2. A rivet setting tool according to claim 1, wherein said alerting means comprises a warning light.

3. A rivet setting tool according to claim 1, wherein said alerting means further comprises means for disabling the rivet setting tool.
