PERESS 1922 (US)

In 1922, Joseph Peress patented the first spherical type joint which used a fluid to transfer the pressure. He went on to build his first suit in 1925 which unfortunately, did not operate successfully. Peress later redesigned the joints on an annular cylinder and piston resting on a cushion of fluid, which came to be known as Type 1. He completed a second suit in 1930 that was dived to 447f/137m and was later successfully tested by the British Royal Navy. The suit was not used again until 1935, when Jim Jarrett dived the wreck of the Lusitania in 312f/96m and was retired from diving in 1937. The second suit he built is owned by the British Science Museum and is on display in Cornwall.
