Abstract: A portable blind fastener installation tool having an installation section actuable for setting the blind fastener and a fastener loading section for automatically front, loading the fastener into the installation section and a piston-valve section for reciprocating the installation section away from and back to its fastener setting position after a fastener has been set to permit the fastener loading section to be moved to a position in front of the installation section while it is away from its fastener setting position whereby the next fastener will be front loaded into the installation section on its movement back to its fastener setting position.

Abstract: A piston-cylinder, pull type installation tool operable from a source of high hydraulic pressure for setting large diameter swage type fasteners including a pin and a collar by application of a relative axial force thereto with the tool having a pair of piston-cylinder combinations arranged in tandem with both of the piston-cylinders being utilized to provide the pull force to swage the collar to the pin and with only one of the piston-cylinders being utilized to provide the collar ejection force to eject the collar from the tool and with at least some of the hydraulic porting being provided through the tandem piston construction.
