  • Reduced shear stress end fitting
    Patent number: 3960459
    Abstract: An end fitting for a hawser which reduces the shear stresses generated win the hawser. The hawser is embedded in a tapered plug, which fits within a complementary member which does not surround the tapered plug for its full axial length. As a result of this geometry, the shear stress which results from the combined tensile and compressive stresses within the hawser and plug is reduced thereby allowing a greater tensile load to be exerted upon the hawser.
