The timeline of underwater diving technology is a chronological list of notable events in the history of the development of underwater diving equipment.With the partial exception of breath-hold diving, the development of underwater diving capacity, scope, and popularity, has been closely linked to available technology, and the physiological constraints of the underwater environment.
1842 sketch of the Deane brothers' diving helmet Standard diving dress with Dräger DM-40 semi-closed circuit nitrox rebreather set. In 1405, Konrad Kyeser described a diving dress made of a leather jacket and metal helmet with two glass windows. The jacket and helmet were lined by sponge to "retain the air" and a leather pipe was connected to ...
The usual meaning of diving helmet is a piece of diving equipment that encases the user's head and delivers breathing gas to the diver, but the term "diving helmet", or "cave diving helmet" may also refer to a safety helmet like a climbing helmet or caving helmet that covers the top and back of the head, but is not sealed. These may be worn ...
John Deane (1800–1884; known as The Infernal Diver), with his brother Charles, invented the diving helmet and performed diving operations at the wreck of the Mary Rose. [1] They received their education at The Royal Hospital School, Greenwich and were both in attendance in 1812.
Scuba diver of the late 1960s. The history of scuba diving is closely linked with the history of the equipment.By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered; open-circuit surface supplied equipment where the diver's exhaled gas is vented directly into the water, and closed-circuit breathing apparatus where the diver's carbon ...
Heinke's diving helmets had three similarly shaped circular windows. They did not have the outer protective grills as in other helmets; thus they had better visibility for divers, and it was easier to keep the windows clean. Heinke's main competitor was Siebe Gorman who also made diving helmets, and Heinke constantly tried to improve on designs ...
Hard hat diving is any form of diving with a helmet, including the standard copper helmet, and other forms of free-flow and lightweight demand helmets. The history of breath-hold diving goes back at least to classical times, and there is evidence of prehistoric hunting and gathering of seafoods that may have involved underwater swimming.
Standard diving dress, also known as hard-hat or copper hat equipment, deep sea diving suit or heavy gear, is a type of diving suit that was formerly used for all relatively deep underwater work that required more than breath-hold duration, which included marine salvage, civil engineering, pearl shell diving and other commercial diving work, and similar naval diving applications.
