  • Method and apparatus for split sleeve cold expansion of openings in structural members
    Patent number: 5127254
    Abstract: A split sleeve (S) is deposited into a sleeve loader (24, 24'), with a lower end of the sleeve (S) on a sleeve support surface (154). A mandrel (M) carried by a puller tool (10, 10') is inserted into the sleeve loader (24, 24'), and through the sleeve (S), to position the sleeve (S) on a small diameter portion (50) of the mandrel (M), and an end portion of the sleeve (S) within a nosepiece (12), against a sleeve end contacting surface (66). The tool (10, 10') is moved away from the sleeve loader (24, 24') to pull the mandrel (M) out from the sleeve loader (24, 24'). Then the mandrel (M) is inserted into an opening (16) in a workpiece (14). The tool (10, 10') is moved endwise to place the sleeve (S) within the opening (16) and a workpiece contacting end surface of the nosepiece (12) into contact with the workpiece (14). The tool (10, 10' ) is then operated to retract the mandrel (M).
