1. A load indicating assembly, said load indicating assembly comprising:

  • a load indicating member further comprising;

    a shank, which, when stressed longitudinally, is subject to elastic deformation such that one portion thereof moves relative to another portion thereof;

    a first flat surface formed adjacent one longitudinal end of said shank;

    an indicator pin having one longitudinal end disposed adjacent said first flat surface and an other longitudinal end disposed remote therefrom, said other longitudinal end being secured to said shank at a location remote from said first flat surface, said pin being unaffected by said elastic deformation of said shank; and

    a second flat surface formed at said one longitudinal end of said pin, said second flat surface being substantially coplanar with said first flat surface when said shank is unstressed, said second flat surface providing a reference for measurement of the elongation of said shank; and

    a load measuring device further comprising;

    adapter means disposed adjacent said first flat surface;

    probe means movably interconnected with said adapter means, said probe means being selectively engagable with said second flat surface; and

    feet means extending from said adapter means for engagement with said first flat surface, said feet means being disposed in an array about said probe means such as to position said adapter means on said first flat surface in a manner placing said probe means in axial alignment with said pin;

    measurement means responsive to the displacement of said probe means relative to said adapter means such that said measurement means provides a measurement of the elongation of said shank relative to said pin when said shank is stressed longitudinally.
