ABSTRACT:
Apparatus for loading and unloading of ships, including a stand pipe on a dock, an inner jib pipe, a beam approximately parallel to the inner jib pipe, and an outer jib pipe whose free end has a pipe line coupling for connection to the coupling device of a ship. The inner jib pipe at one end is connected to and pivotal in a vertical plane on the stand pipe. The inner jib pipe on its other end supports the outer jib pipe, which is pivotal in the same plane. An extension of the outer jib pipe extending beyond the latter pivot is pivotally connected to one end of the beam. The beam towards its other end is connected pivotally to a link which itself is pivotally connected to the stand pipe. The pivot bearings for the beam and inner jib pipe are arranged coaxially on the stand pipe. The beam and the inner jib pipe are extended beyond the pivot bearing with the stand pipe and carry compensating weights. The improvement which comprises an extension link interposed between said beam and an extension of the outer jib pipe pivotally connected at one end to one end of the beam and at its other end to the outer jib pipe extension. A reciprocal drive mechanism is mounted on said beam and connected to said extension link for modifying the effective length of said beam for translating said outer jib pipe and pipeline coupling to and from a generally vertical rest position.
