Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
144 words
Means for protecting a towing or mooring cable comprising an elongated sleeve of resilient wear-resistant material with at least one longitudinally extending external flat face, said sleeve being split longitudinally into individual unitary sleeve parts which define a cable receiving longitudinal guideway therebetween the exposed surface of which is comprised of said resilient wear-resistant material, said sleeve parts including a metal strap bonded and imbedded within each of said sleeve parts behind said exposed surface of said guideway so as to remain out of contact with a cable placed through said guideway, said metal straps being positioned adjacent each end of said elongated sleeve, holes extending through each end of the metal straps, holes extending through said sleeve parts which are coaxial with the holes in said straps, and screw means extending through each coaxial pair of holes to secure said sleeve parts together.
