  • Patent number: 7290317
    Abstract: A blind rivet setting tool has a construction in which a tubular spring-biased handle gripped by an operator moves axially of the tool. An interlock between a trigger lever and the handle prevents operation of the tool until a rivet held by the tool is properly positioned in a hole of a workpiece.
    Type: Grant

  • Patent number: 6418599
    Abstract: A setting apparatus 30 in which a mandrel of a blind rivet is inserted into a hole 47 of a nose at the front end of the setting apparatus, and wherein a rivet body of the rivet is projected from the nose into a mounting hole of a workpiece. The mandrel is pulled rearward of the nose with a force capable of breaking the mandrel and expanding a shank of the rivet body so that the rivet is set in the workpiece by the expanded shank and a flange of the rivet body, followed by discharging of the broken mandrel from the setting apparatus. The force for pulling the mandrel is obtained from hydraulic pressure of a hydraulic cylinder 34. The hydraulic pressure is produced by a piston 41 which moves in a pneumatic cylinder 39 adjacent to the hydraulic cylinder. The nose 31 is axially aligned with an apparatus body 33 including the hydraulic cylinder and the pneumatic cylinder 39 along the longitudinal direction of the setting apparatus 30 from the front end to the rear end thereof.
