Abstract
An attachment for a power driven installation tool for a threaded fastener and a stress plate includes a barrel assembly connectable at a first end to the driver and terminating in an outer barrel at a second end. The outer barrel terminates in a stress plate holder and the stress plate holder is free to move with respect to the rest of the tool. In a preferred embodiment, a floating barrel is positioned for slidable movement within the distal end of the outer barrel and a stress plate holder is rigidly secured to the floating barrel and external of the outer barrel.

In a power driven installation tool for installing threaded fasteners and stress plates by screwing a fastener through a stress plate and into a workpiece and including an outer barrel and a terminal plate holder connected thereto for retaining the stress plate as the fastener is screwed therethrough, the improvement comprises means for providing free movement of the plate holder relative to the outer barrel to permit the stress plate to ride up the fastener as the fastener dwells on the workpiece during installation.
An attachment for a driver to form a power driven installation tool for a threaded fastener and a stress plate comprising:
- A. a barrel assembly connectable at a first end to such a driver and terminating in an outer barrel at a second end, said barrel assembly having a bore axially therethrough;
- B. means for introducing a fastener into the barrel assembly;
- C. a floating barrel positioned for free slidable movement within the bore of a second end of the outer barrel;
- and
- D. a stress plate holder rigidly secured to the floating barrel and external of the outer barrel.
