Abstract

An equalizer socket including a socket body, a plurality of grooved wire receiving wedges removably inserted therein and at least one center wedge having a greater taper in bearing contact with the ropes of the grooved wedges, and constraining means associated with the end of the socket body for the center wedge.

Claims

1. A wire rope equalizer socket comprising a relatively elongatged housing having first and second ends, means adjacent said first end for connecting said housing to chain means, an opening extending inwardly of said housing from said second end for the receipt of a pair of looped wire ropes, first and second wedges positioned in said opening, each wedge having an outwardly-facing groove adapted to receive a loop of a wire rope, a first wire rope having a loop received in the groove of said first wedge and a second wire rope having a loop received in the groove of said second wedge, said first and second rope and said first and second wedges being disposed in side-by-side relation in said opening with said loops being coplanar and with said wedges being tapered toward said second end, a third grooved wedge in said opening in bearing relation to said first and second rope loops and being tapered toward said first end, and pin means removably mounted in said housing extending generally perpendicularly to the plane of said loops for maintaining said third wedge against longitudinal movement out of said opening but to permit lateral movement in said plane for equalizing the tension in said first and second ropes upon longitudinal outward movement of one of said loops in said opening.

2. The socket of claim 1 in which said third wedge has a greater taper than each of said first and second wedges.

3. The socket of claim 1 in which each of said first and second wedges has a wedging taper of about 15°

, said third wedge having a non-wedging taper of at least about 24°

.

4. The socket of claim 1 in which said pin means includes a wedge element slidably lodged in said socket and removable retaining means for maintaining said pin means in position in said socket.

5. A wire rope equalizer socket comprising a relatively elongated housing having first and second ends, means adjacent said first end for connecting said housing to chain means, an opening extending inwardly of said housing from said second end and first and second grooved wedges and first and second looped wire ropes received in said opening, each wire rope being looped about a separate one of said grooved wedges, said loops and wedges being disposed in side-by-side relation in said opening and with said wedges being equipped with a wedging taper toward said second end, a third grooved wedge in said opening in bearing relation to said first and second loops and being equipped with a non-wedging taper toward said first end, and pin means removably mounted in said housing.

6. The socket of claim 5 in which said pin means is a wedge element equipped with a non-wedging taper, said socket being equipped with an aligned slot and pocket having sides of a non-wedging taper, said pin means being removably mounted in said slot and pocket, and bar means releasably maintaining said pin means in said slot and pocket.

7. The socket of claim 6 in which said wedge element is equipped with a lifting eye.

8. A wire rope equalizer socket for a plurality of wire ropes comprising a relatively elongated housing having first and second ends, means adjacent said first end for connection to chain means, an opening extending inwardly of said housing from said second end and a plurality of looped wire ropes and an equal plurality of grooved wedges received in said opening, each wire rope being looped about a separate one of said grooved wedges, said loops and wedges being disposed in side-by-side relation in said opening and with said wedges being tapered toward said second end, grooved wedge means in said opening in bearing relation with each pair of adjacent loops and being tapered toward said first end.

9. The socket of claim 8 in which said housing includes concentric pipes defining an annular opening to accommodate at least three looped wire ropes.
