Another patent for a movable coupling that could be used for various purposes including diving suits. Like Drager’s patent, the search for the ideal coupling continued and was finally solved by Peress in 1929.
Manfred Carlon claims:
1 A watertight device for jointed pipe connections, in which the organs jointed to one another are surrounded by watertight flexible inner and outer walls attached to the joint arms, the said organs being thus enclosed in a separate joint chamber, for the purpose of preventing the fluid surrounding the pipe connection being in ‘contact with the joint surfaces when under pressure
2 In a watertight device according to Claim 1, the provision of a channel leading to the joint chamber for filling this chamber with a suitable fluid, liquid, gas or the like at a greater pressure than the 125 i 143,867 greatest pressure of the fluid surrounding the joint chamber, for the purpose of holding the flexible walls of the joint chamber away from the joint parts, thus alllowing the latter to move freely over one another.
3 A watertight device according to Claims 1 and 2 in which the inner flexible wall of the joint chamber is provided with an armature of steel wire or the like of sufficient strength to resist the maximum difference in pressure between the fluid on the inside and on the outside of the arms of the joint.
4 A watertight device according to claims 1 and 3 characterised in that the jointed organs of the joint connection and so formed that in all positions of the joint they form a shield against the flexible outer wall, surrounding the joint for the purpose of preventing this wall from being pressed into the pipes by the outer water pressure, if the pressure on the inside of the joint should cease.
The watertight device substantially as described with reference to the accompanying drawings.
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!
