Abstract:
In combination, a circular cord having a diameter and an axial length, and a spherical clamp adapted to hold fast in a position of attachment at a selected site along said cord axial length against a pulling force exerted longitudinally of said cord, said spherical clamp comprising a bolt having externally threaded bifurcated legs having in their bifurcation internal side surfaces and a bottom surface cooperating to bound a cord-engaging compartment, plural spaced apart pointed teeth projected from said bottom surface into said cord-engaging compartment, a cord disposed in said cord-engaging compartment, a nut having an internally threaded bore disposed in threaded engagement to said externally threaded legs of said bolt so as to be adapted upon rotation to be urged in closing movement toward said bolt, and a washer having an interposed operative position between said nut and bolt and plural spaced apart pointed teeth in opposite facing and offset relation to said teeth of said bolt, whereby said closing movement contributes to an impaling of said cord upon said pointed teeth to hold fast said attached position of said bolt and nut on said cord.
