Abstract

A crowfoot socket for a drag line bucket having square-headed pins angularly related in shank end abutting relation to provide pivot connections for the drag chains and dump rope associated with the bucket.

Claims

1. A crowfoot type drag rope socket assembly for interconnecting a drag rope with a drag chain and a dump rope, the latter being connected to a drag line bucket, comprising a relatively elongated unitary fitting having a first end adapted to be connected to a drag rope, said fitting adjacent said one end being tubular and tapered in proceeding toward said first end and adapted to receive a drag rope socket wedge over which said drag rope is reevable, said fitting adjacent the other end having two pairs of integral longitudinally projecting spaced apart legs disposed in side-by-side relation with the legs in each pair being parallel, the space between the legs in each pair being adapted to receive a link of a drag chain, the space between the pairs of legs being adapted to receive a dump rope socket, said pair of legs being generally divergent in proceeding toward said other end, said legs being equipped with transverse bores extending transversely to the length of said legs, the bore in each of the outer legs of each pair being polygonal, a relatively elongated pin for each pair of legs mounted in the bores thereof and having a polygonal shaped head received in the associated outer leg bore, each pin having a shank terminating in an integral cylindrical section having an axis disposed in angular relation to the axis of the remainder of said pin whereby said pins are adapted to abut at their shank ends to provide a pivot mounting for said dump rope, and means interconnecting each pin head and said fitting to retain said pins in place.

2. The assembly of claim 1 in which said polygonal shape of said head and outer leg bore is a square oriented with the one side of said square closest to the end of said outer leg being generally perpendicular to the line of force application by said drag chain to said pin.

3. The assembly of claim 2 in which said outer leg has a second bore communicating with the pin head receiving bore thereof, said one side of said head being equipped with an opening, a removable pin extending through said second bore into said opening, said outer leg adjacent a side of square bore being equipped with a relief to facilitate removal of said pin by prying.

4. The assembly of claim 1 in which said pin has a first shank portion immediately adjacent said head, said first shank portion being cylindrical, said integral cylindrical section being spaced from said head and having a diameter less than the diameter of said first shank section.
