Thread clamping device including internal sensing, reporting and external detector

Abstract

The present device relates to a thread clamping device including a plurality of movable segments with threaded inner surfaces suitable for engaging a threaded rod and including a strain gauge and transmitter therein for measuring the actual strain on the device and for transmitting this information to a receiver external to the thread clamping device, such as a receiver and display integral with a wrench for applying torque to the thread clamping device.

What is claimed is: 
     
         1 . A load wrench for tightening a thread clamping device wherein said load wrench is equipped with a receiver for sensing loads transmitted from said thread clamping device, and wherein said thread clamping device is equipped with a compatible load sensing transmitter.
