World War II-era U.S. Navy Navigational Sounding Machine manufactured by John E. Hand & Sons Co. (c. 1940–1944). It is a mechanical depth finder used by naval and Liberty ships to measure ocean depth via a weighted sounding line and reel.Function: A long wire cable with a heavy lead weight was spooled on the reel and lowered to the sea floor. Once the weight hit the bottom, slack in the line registered on the central mechanical dial to show the depth in fathoms/feet.Operation: Operated manually using the side hand-crank and top brake/release handle, typically mounted on the boat deck of cargo and auxiliary vessels.Construction: Heavy gray-painted cast iron and bronze mechanical components designed for marine environments.If you would like, I can provide more details on:How the sounding wire and lead-line weight were rigged.
