Bildnummer 11904314
| Halley's diving bell. Engraving of Halley's diving bell of 1716. Although best known for discovering the famous comet named after him,the astronomer & physicist Edmond Halley (1656-1742) was also the first to develop a commercially successful diving bell,which led to greatly improved wreck salvage in shallow waters. The diver's helmet,called a "cap of maintenance",was connected to the bell by a leather pipe held open by a steel spring. Air in the bell was continuously replenished by relays of weighted buckets carrying fresh air from a ship overhead. Halley used the bell himself,claiming the air it delivered was so sweet that he once drank a bowl of punch on the sea bed | |
