Pulley Chain (Belly Belt) in Forward Torpedo Room

To the average person, the chain dangling from the top looks like just any ordinary chain, but you will notice that every second link is enclosed in a rubber ball. A normal chain used for a chain block arrangement is extremely noisy, but by having a rubber “ball” at every second link, it makes the chain block totally quiet, therefore allowing you to carry on with the shifting of torpedoes even in a “quiet” state.
