1. An apparatus to extend a working length of an elevator assembly of a drilling rig, said apparatus comprising:
a) a unitary body comprising
i) a first coupling portion,ii) a second coupling portion, andiii) a transition portion connecting said first coupling portion with said second coupling portion; b) said first coupling portion extending away from said transition portion; c) said second coupling portion extending away from said transition portion in a direction opposite the direction that said first coupling portion is extending; d) a furthermost portion of said first coupling portion extending away from said transition portion defining a first end of said unitary body; e) a furthermost portion of said second coupling portion extending away from said transition portion defining a second end of said unitary body; f) said unitary body having a unitary-body-length measured from said first end of said first coupling portion to said second end of said second coupling portion; g) said first coupling portion comprising an opening that extends into said first coupling portion, said opening transitioning into a channel situated between a first projecting side member and a second projecting side member of said first coupling portion; h) said channel sized to receive an eye shaped loop portion of an elevator link; i) said first projecting side member comprising a first bore having an axis that is transverse to a longitudinal axis of said first projecting side member; j) said second projecting side member comprising a second bore having an axis that is transverse to a longitudinal axis of said second projecting side member; k) said first bore of said first projecting side member and said second bore of said second projecting side member aligned coaxially so that a fastener may pass through said first bore, into said channel, through the eye shaped loop of the elevator link, and through said second bore; l) said second coupling portion comprising a third bore, said third bore having an axis that is transverse to a longitudinal axis of said unitary body, m) said second coupling portion being connectable with a female end of a bail extension by way of a male-female connection; and n) said apparatus extends the working length of an elevator assembly of a drilling rig by the length of the unitary-body-length. |
