1897 Arthur McQuillan

The invention of Arthus McQuillan relates to certain improvements in the mode of constructing diving dresses so as to enable them to resist the pressure incidental to deep diving, and consist essentially in providing the dress with a number of tubular rings -of iron or other suitable metal. These rings are sewn between two or more thicknesses of the material composing the dress, a sewn seam being between each ring. The dress is further provided with an external waterproof covering. The invention also comprises. means for supplying air by means of an india rubber tube to the diver, and means for conveying the foul air from the diver to the surface of the water.

A are the tubular rings, sewn between two or more thicknesses of the material composing the dress, a seam is sewn between each ring A. The sleeves bl and legs b 2 of the dress are constructed in this manner. The rings A are preferably tubular. R are flanged or other suitable joints having one ring only between said joints. These joints are coincident, or nearly so, with the knee, leg and arm joints of a diver. The object being to afford greater freedom of movement. B are coverings for the feet composed of copper or other suitable metal of sufficient strength to resist pressure of water at great depths, and of the form or shape of Wellington boots. The feet covering or boots B are secured to the legs b2 of the dress preferably by flanged joints c, and the lower part of the body, and the arms, are secured to the metallic covering E by similar flanged joints d and f. E is a covering composed of bronze or other suitable metal, which forms a protection for the upper part of the body, cylindrical in shape around the breast , and back and of a dome or spherical form from the shoulders to the helmet or head covering G.
