Info: One of the earliest Fleuss-Siebe, Gorman self-contained diving apparatus consisted of a double helmet-one within another-spaced apart as shown in the picturepage, and forming the oxygen container in which the gas was compressed to about 30 atmospheres. The ori-nasal mask and tube, were used in conjunction with the helmet. You also find a breastplate of the helmet, and the CO2 absorbent chambers forming parts of the same apparatus. The CO2 absorbent consisted of pieces of rubber sponge saturated with a solution of caustic potash.

 

  The wearer had his head in a 30 bar pressure vessel!
