Abstract: Lockbolt collar feed mechanisms, lockbolt installation tools, and methods of installing lockbolt assemblies are disclosed. Lockbolt collar feed mechanisms comprise a collar cartridge and a mounting bracket operatively coupled to the collar cartridge and configured to be operatively coupled to a lockbolt installation tool. The collar cartridge has a delivery position, in which an exit port is positioned to position a lockbolt collar forward of the lockbolt installation tool's anvil, and a retracted position, in which the collar cartridge is pivoted and translated rearward relative to the delivery position. The collar cartridge is biased toward the delivery position and moves from the delivery position to the retracted position responsive to a user urging the lockbolt installation tool and the lockbolt collar feed mechanism toward and into engagement with a workpiece.
