ABSTRACT:
The anchored end of a mast of a gin-pole derrick is pivotally mounted on a releasable connector. The connector comprises a pair of laterally spaced support brackets having a retaining pin reciprocally mounted thereon for movement between a first position attaching the mast on a large portion of the pin and a second position whereby the mast may be released and detached from a smaller portion of the pin. A compression coil spring is mounted between the pin and one of the support brackets to normally bias the pin to its former condition of operation, attaching the mast on the connector.
