A nose assembly attachable to an actuating tool for pulling a pin type fastener through aligned holes in two or more workpieces includes a pin-engagement jaw structure that is locked to or unlocked from the fastener through a lost motion connection. A transverse pin that extends radially through a rear portion of the jaw structure and into an axial groove in an annular housing functions in response to axial motion of a collet member that is operated within the housing by a reciprocable piston in the actuation tool.

Fastener nose assembly with rearward jaw release

An offset pin puller apparatus usable with a fluid-operated actuator tool for exerting an axial pulling force on a grooved fastener pin projecting through a workpiece. Jaws mounted within the apparatus are held against axial motion while an associated collet moves axially to cam the jaws into clamped engagement with the fastener pin. The jaws are released from the fastener pin by abutment of a jaw release assembly with an inner wall of the apparatus. Such abutment effects an axial and radial separation of the jaws from the collet during a return stroke of the actuation tool.

Offset nose assembly with pin releasing assembly for fastener

An installation tool for pin and collar fastener assemblies includes an ejector rod slidably mounted in an axial blind bore in the actuator portion of the tool. Within the blind end of the axial bore is an elongated resilient bumper adapted to engage the ejector rod to absorb momentum and energy associated with high speed movement of a severed pintail. The resilient bumper minimizes shock loading of the ejector rod and thereby prolongs the ejector rod service life.
