Abstract
Abstract A releasable connector has the mast of a gin-pole derrick movably mounted thereon. The connector comprises a horizontally disposed pin mounted between laterally spaced support brackets and a bushing, loosely mounted on the pin. A lock nut is threadably mounted on the pin to permit selective axial movement of the bushing for removing the gin-pole mast therefrom.
