Abstract
A blind riveter has a T-shaped housing whose one T-arm forms a working tip provided with a reciprocal internal chuck, whose other arm is formed as a hollow compartment, and whose central T-leg incorporates a pneumatic cylinder. The cylinder can displace the chuck to pull the mandrel of a blind rivet, thereby pulling the rivet back against the tip to upset the rivet. A passage extends from the chuck back into the compartment. The cover of the compartment is formed with a jet pump that is powered off the pneumatic supply that operates the riveter and serves to suck a mandrel pulled from a rivet back from the chuck into the compartment.
