The original standard diving equipment was a copper helmet or "bonnet" (British English) clamped onto a copper breastplate or "corselet", which transferred the weight to the diver's shoulders. This assembly was clamped to a rubber gasket on the dry suit to make a watertight seal.
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.
A long leather hose attached to the rear of the helmet was to be used to supply air, the original concept being that it would be pumped using a double bellows. A short pipe allowed breathed air to escape. The garment was to be constructed from leather or airtight cloth, secured by straps. Later, it was developed into a diving apparatus.
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.
Charles Deane had little success marketing the apparatus as a smoke helmet, so in 1828 he and his brother decided to find another application for it and converted it into a diving helmet and marketed the helmet with a loosely attached "diving suit" so that a diver could perform salvage work but only in a full vertical position, otherwise water ...
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 ...
Hilbert Joseph Savoie Jr., [1] known as Joe Savoie (25 January 1926, Pointe au Chen, Louisiana – 10 March 1996, Boutte, Louisiana), [2] [3] was a pioneering commercial diver and inventor of lightweight diving helmets, particularly the neck dam feature which allows the helmet to be sealed to the diver independently of the diving suit.
The Company was notable for developing the "closed" diving helmet of the standard diving dress and associated equipment. As the helmet was sealed to the diving suit, it was watertight, unlike the previous "open" helmet systems. The new equipment was safer and more efficient and revolutionised underwater work from the 1830s.
