Abstract

A socket fitting for use with wire rope including wedge means received in a socket to be clamped to the wire rope as a result of a wedging action produced by a tension applied to the rope tending to draw the rope through the socket. Securing means are provided on the wedges for maintaining the wedge elements clamped to the wire rope notwithstanding a discontinuation or reversal of the tension forces. Means are further provided on the wedges for effectively precluding withdrawal of the wedges from the socket as by such a reversal of the tension force.

Claims

1. A socket fitting for use with wire rope, comprising:

a socket having a through bore defined by opposite, wedge surfaces approaching each other at an inner end of the bore;

a first wedge element in said bore having an outer surface engaging one of said wedge surfaces;

a second wedge element in said bore having an outer surface engaging the other of said wedge surfaces, said wedge elements having inner surfaces adapted to engage a wire rope extended longitudinally through said bore therebetween, said wedge elements being caused to clamp said wire rope effectively positively against longitudinal withdrawal through said inner end of the bore as a result of a wedging of the wedge element against said wire rope by said wedge surfaces of the socket, said wedge elements having radially movable inner ends projecting from the inner end of said bore; and

securing means secured to said projecting inner ends of the wedge elements for adjustably clamping said inner ends of the wedge elements to said wire rope notwithstanding a discontinuation of the wedging of said wedge elements by said wedge surfaces, said securing means and socket defining cooperating shoulders for positively limiting longitudinal outward movement of the clamped wire rope and wedge elements in said socket bore.

2. The socket fitting of claim 1 wherein cooperating abutment means are provided on said socket and securing means for limiting the outward movement of the clamped wire rope and wedge elements in said socket bore.

3. The socket fitting of claim 1 wherein said wedge elements define extension portions extending inwardly from said inner end of the socket bore each defining a transversely outwardly opening channel and said securing means is secured to said extensions with portions of the securing means being received in said channels.

4. The socket fitting of claim 1 wherein said wedge elements Define extension portions extending inwardly from said inner end of the socket bore each defining a distal transversely outturned flange and said securing means is secured to said extensions longitudinally outwardly of said flange.

5. The socket fitting of claim 1 wherein said securing means comprises means removably secured to the wedge elements.

6. The socket fitting of claim 1 wherein said securing means comprises a removable clamp.

7. The socket fitting of claim 1 wherein said wedge elements include portions exposed outwardly of the wedge socket means and said securing means engages said exposed portions at a position spaced from said socket means in the made-up arrangement of the fitting subsequent to the exertion of said longitudinal pull on the wire rope.
