Two Australian inventors, John Buchanan and Alexander Gordon, of Melbourne patented in 1894, a deep-water diving
dress of waterproof material, stiffened internally by spiral wires. A later
patent, taken out by Gordon alone, embodied various improvements in the
fastening of the flexible material to the standing portions of the dress, such
as the helmet; and it also provided for the use of jointed radius-rods running
along the sleeves and trousers to prevent them from collapsing under pressure,
while leaving them free to flex. This was made in Siebe, Gorman & Co.’s old
works in London
in 1898. R.H. Davis was present at its trial off the Scottish coast.
