"Diving Apparatuses are contrivances by means of which divers are enabled to remain a considerable time under water. As the most skillful divers are unable to remain under water more than two or three minutes without artificial respiration, means have been devised by hermetically sealed helmets, diving bells, and diving dresses, so that they can stay for several hours at a time at considerable depths of water and at the same time carry on their work."—(Charles Leonard-Stuart, 1911)

"The diving dress envelops the whole body of the diver, the upper portion a being the "helmet," the intermediate portion b the "breast-plate," and the lower portion c the "dress." The hose by which the air is supplied is shown at d, and e is the "life" or "signal" line, which is attached to the diver's waist, and by which he makes signals and is hauled to the surface. The water-proof material of which the dress is made is very generally sheet india-rubber covered on both sides with tanned twill to protect the india-rubber from injury." — Encyclopedia Britannica, 1893

A standard diving dress consists of a metallic (copper, brass or bronze) diving helmet, an airline or hose from a surface supplied diving air pump, a canvas diving suit, diving knife and boots. An important part of the equipment is the addition of lead weights, generally on the chest, back and boots, to counteract the buoyancy of the helmet and diving suit.
