Abstract: A manually-operated fastener installation tool is provided with a self-contained cartridge or magazine for feeding lockbolt collars to an installation position adjacent the tool nosepiece. A fixed, inflexible feed path directs the collars from the cartridge towards the nosepiece to eliminate the jamming which occurs with conventional flexible feed tubes. The entire collar feed path is pivotally mounted within the tool to avoid complex shuttling movements of the collars across transition regions and discontinuities in the feed path to further reduce jamming.
