Wedge-type rope socket connection and method
First Claim
1. A socket-wedge connection for the wedge-type rope socket for an excavating bucket or the like comprising a relatively elongated socket having a larger end and a smaller end, a tapered passage extending from one end to the other, a rope in said passage looped upon itself to provide two lengths of rope in said passage with a loop adjacent said larger end, and a relatively elongated wedge between said two lengths, said wedge having a pair of longitudinally-extending wedge-forming means with collapsible insert means therebetween for relieving pressure on said two lengths, said insert means including a plurality of longitudinally tapered block means arranged to slide relative to each other unless constrained against relative longitudinal movement.

- 1. A socket-wedge connection for the wedge-type rope socket for an excavating bucket or the like comprising a relatively elongated socket having a larger end and a smaller end, a tapered passage extending from one end to the other, a rope in said passage looped upon itself to provide two lengths of rope in said passage with a loop adjacent said larger end, and a relatively elongated wedge between said two lengths, said wedge having a pair of longitudinally-extending wedge-forming means with collapsible insert means therebetween for relieving pressure on said two lengths, said insert means including a plurality of longitudinally tapered block means arranged to slide relative to each other unless constrained against relative longitudinal movement.
- 4. Socket-wedge for a wedge-type rope socket connection of an excavating bucket comprising two wedge-forming halves pivotally interconnected adjacent the small wedge end and equipped with confronting surfaces adjacent the larger wedge end, and a collapsible insert between said surfaces, said insert including a plurality of stacked tapered blocks adapted to slide relative to each other in the absence of longitudinal constraint.

6. A method of manipulating a wedge-type rope socket connection for an excavating bucket or the like comprising providing a relatively elongated socket having a tapered passage extending from one end to the other, installing a multiple-part wedge and rope in said passage wherein said wedge includes outer tapered members and a collapsible insert and, when disassembly of said connection is required, collapsing said element, said insert including a plurality of stacked tapered blocks slidable with respect to each other upon removal of a block sustaining force, and said collapsing step includes removal of said sustaining force.
