Abstract: A swage fastening tool is disclosed, the tool including damper valve concentrically positioned about a piston which displaces the fastener being swaged. The damper valve moves with the piston when the trigger structure of the tool is actuated to supply pressurized fluid to the piston, the damper valve being positioned relative to the piston and the flow path of the fluid to meter flow both to the piston during swaging and from the piston after swaging has been completed. The trigger is provided with a camming feature to create a component of a trigger movement to actuate a flow control valve in a simplified manner and a self-restoring resilient arm portion to return the trigger structure to its initial position.

Abstract: An improved hand-held collar dispenser for securing collars to a lockbolt or other fastening piece is disclosed. The dispenser has a feeding end and a dispensing end connected by a channel. A pair of retention clips selectively retains the collars within the body until the user chooses to dispense a collar. The retention clips are pivotally mounted to a guide block which moves between an extended position and a retracted position. When the guide block is in the retracted position, the tail of each retention clip abuts a respective angled surface preventing the retention clips from rotating. As the guide block moves between the retracted and extended positions, each retention clip slides along its corresponding angled surface permitting the retention clips to rotate to an open position in which a collar is permitted to pass between the claw ends of the retention clips and exit the dispenser.

Abstract: An end cap assembly for a fastener installation tool is shown. The end cap assembly includes an end cap received within a housing of the fastener installation tool. The end cap assembly also includes a protective cover plate positioned to cover the joint between the end cap and the housing. The end cap assembly further includes a lock for preventing the end cap from disengaging the housing when the end cap is positioned within the housing. The end cap is configured with a countersink and corresponding driver to facilitate removal of the end cap from the housing of the fastener installation tool even if the housing has been deformed.
