  • Anchor stowing arrangement
    Patent number: 4214545
    Abstract: An anchor is stowed entirely within a recess in the bottom of a vessel, by means of a fairlead within the recess comprising a sheave supported in a bracket pivotable about a vertical axis in the center of the recess, along which axis the pull of the anchor winch occurs; the bracket has a hollow space for receiving the shank of the anchor, and a spring-based roller holds the anchor line against the sheave. The lower part of the bracket has guide edges extending completely around the pivot axis except for a side portion corresponding to the width of the sheave for automatically guiding the anchor line onto the sheave.

  • Hauling-in a rope and chain line
    Patent number: 4078768
    Abstract: In a method of hauling-in a rope and a chain interconnected by a coupling link, using a winch for the rope and a wildcat for the chain, the rope is hauled-in on the winch until the coupling link has moved past the wildcat, whereafter the chain is locked, and the winch is reversed to dump the chain on the wildcat and make it form a sling on the side leading to the chain box, whereafter the wildcat is started and the chain is unlocked.

  • Arrangement for controlling the engagement of a chain with a chain sheave, such as a cable lifter or wildcat
    Patent number: 4034556
    Abstract: A chain link, which is asymmetric about its longitudinal axis, one longitudinal side of the link being convex, the other being concave, or a plurality of such links alternating with common type links, is used for twisting the chain into predetermined synchronization with the pockets and teeth (whelps) of a chain sheave (cable lifter, wildcat), particularly as applied to a chain and a rope interconnected by a coupling link larger than a common link.

  • Linking members for connecting a rope and a chain
    Patent number: 3977181
    Abstract: The invention relates to a linking member for connecting a rope and a chain to provide a combined line, e.g. for use as a mooring line for semi-submersible drilling rigs. The linking member comprises a shell, an intermediate member pivotably mounted within the shell, and a rope attachment sleeve pivotably mounted in the intermediate member, the rope extending from the sleeve out of one end of the shell. Moreover, the shell is constructed at its other end with a loop or bar for engagement with the first link of the chain.
