Joseph-Martin Cabirol
Encyclopedia
Joseph-Martin Cabirol was a French man. In 1855 he patented a new model of standard diving dress
, mainly from Augustus Siebe
's designs, and afterwards he made them. The suit is made out of rubberized canvas. The helmet, for the first time, includes a hand-controlled tap that the diver uses to evacuate his exhaled air. The tap includes a safety valve
which stops water from entering the helmet. Until 1855 diving helmets were equipped with only three circular windows (front, left and right sides). Cabirol's helmet introduced for the first time the later well known fourth window, in the upper front part of the helmet and letting the diver watch above him. Having been presented to the Exposition Universelle in Paris
Cabirol's diving dress won the silver medal. This original diving dress and helmet are now preserved at the Conservatoire National des Arts et Métiers
in Paris.
His gravestone has a carving of a goat on it, as 'cabirol' is Occitanian for "goat".
