Abstract
An improved rope socket for downhole operations, capable of separating within the wellbore to permit removal of upper components and attached wireline, while lower components including an uphole-facing fishing neck remain attached to a tool string or fish within the wellbore. Also, an improved drop bar for actuating a release mechanism of the improved rope socket. The improved drop bar includes wheel assemblies having integrated axles to provide a stronger axle capable of offset placement along the circumference of the drop bar.
