Abstract A connector for securing a choker cable to a main line cable. The main line cable is fastened to a cylindrical ferrule having an axial bore through which the end of the cable passes. The bore tapers inwardly away from the end of the cable and receives a pair of semi-cylindrical nubbins having a taper matching the taper of the bore. The nubbins are positioned between the cable and the walls of the bore, and the wedging action of the nubbins with the cable and the ferrule securely fastens the cable to the ferrule yet allows the ferrule to be easily released from the cable. A generally U-shaped shackle is rotatably secured to the ferrule by a pair of pins projecting diametrically from the ferrule into respective bores formed in opposite legs of the shackle. One or more choker cables are fastened to the shackle by loops formed at the ends of the choker cables which surround the curved portion of the shackle.
A cable connector for interconnecting a mainline cable with a plurality of choker cables, comprising: a generally u-shaped shackle having side arms in which aligned openings are formed; a pin bridging the space between the side arms of said shackle, said pin having the ends thereof freely rotatable in said openings and restraining means formed on the ends of said pin for preventing endwise movement thereof; a ferrule formed as an integral part of said pin and positioned midway between the side arms of said shackle, said ferrule having a tapered frustro-conically shaped centerbore through which said mainline cable extends; a cable fastening means comprising a pair of semi-frustro-conically shaped nubbins tapered to match the taper of the centerbore of said ferrule, said nubbins each having a semi-cylindrically shaped groove extending along the axis thereof which together form a central cylindrical passage through which said mainline cable extends and is frictionally held between said nubbins, said nubbins contacting the wall of said centerbore over the major surface area of said centerbore in order to maximize the strength and rigidity of said fastening means; and a reinforcing bar extending between said side arms to prevent either withdrawal of the ends of said pin from said openings or spreading of said arms of the shackle responsive to spreading forces applied to said shackle.
