PERFECTIONNEMENTS AUX MORS TRONCONIQUES D'ANCRAGE POUR CABLES ET A LEURS PROCEDES DE FABRICATION

摘要

To prepare a split frustoconic jaw intended for the anchoring of a cable, a part is first taken bounded externally by a frustoconic surface and hollowed by a cylindrical axial channel whose inner surface is advantageously striated. This part is sawed into by substantially axial and radial slashes leaving bridges to subsist of small thickness at the bottom of these slashes throughout the central channel. An assembly ring is mounted in an outer annular groove and the whole is subjected to cementation treatment so as to surface harden the jaw while making the bridges fragile.
