Abstract

A pintail fastener installation tool includes a nose piston cylinder which surrounds a nose piston having a longitudinal bore which is aligned with a jaw opening of a nose assembly. The nose piston also has a venturi bore which meets the longitudinal bore at an angle. When connected to a source of pressurized air and enabled, the venturi bore creates a venturi effect which suctions detached pintails out of the nose assembly and piston into a container. The venturi bore may be disabled by a slide valve which separates the venturi bore from the air feed. The slide valve includes a ring which is positioned around the exterior of the nose piston cylinder. The slide valve is linearly slidable between an open position, which allows pressurized air to flow from the air feed to the venturi bore, and a closed position, which prevents air flow from the air feed to the venturi bore. A pintail container secured to the nose piston cylinder includes a slotted inner bottle and a slotted outer bottle with ribs. The bottles are rotatable relative to one another. The tool is connectable to a pressurized air hose by way of a rotatable air inlet swivel. The tool is ergonomically designed to reduce stresses on the user and facilitate proper positioning of the tool.
