The patent of James F. Long from Texas USA shows an ADS where the waterproofing is obtained by covering the metal suit with waterproof fabric. No other innovations can be found in the patent claim. Supply and return of breathing air via hoses from the surface.
Having thus described the invention, what is claimed as ‘new is:
1. A diving armor including arm and leg sections disposed in spaced relation at their confronting ends, a continuous fabric shield to said arm and leg sections and extending over the space between their confronting ends, a plurality of annular supporting members engaging the interior of the fabric shield between the confronting ends of the arm and leg sections, a plurality of annular supporting members engaging the exterior of the fabric shield and in transverse alinement respectively with the first mentioned supporting members, and a supporting connection between the sections permitting pivotal movement thereof.
2. A diving armor including a torso portion having reduced extensions with transversely curved annular seats,- upper leg sections having transversely curved annular seats corresponding to and underlying the portion of the arm armor.
4. A diving armor including limb armors composed of sections having overlapping ends and provided in said ends with transversely curved annular seats, and a clamping band secured around and conforming to said seats.
5. A diving armor including torso sections and upper and lower arm and leg sections coasting with the torso sections, said arm and leg sections disposed in spaced relation at their confronting ends, a continuous fabric shield to said arm and leg sections and extending over the space between their confronting ends, a plurality of annular supporting members engaging the interior of the fabric shield between the confronting ends of the arm and leg sections, a plurality of annular supporting members engaging the exterior of the fabric shield and in transverse alinement respectively with the first mentioned supporting members, and coacting ears extending from said sections and pivotally united.
Therebreathersite was founded by Jan Willem Bech in 1999. After a diving career of many years, he decided to start technical diving in 1999. He immediately noticed that at that time there was almost no website that contained the history of closed breathing systems. The start for the website led to a huge collection that offered about 1,300 pages of information until 2019. In 2019, a fresh start was made with the website now freely available online for everyone. Therebreathersite is a source of information for divers, researchers, technicians and students. I hope you enjoy browsing the content!
