ROBERT FULTON London august 10th 1806 Description of the drawings of the Submarine Vessel, submarine bombs, and mode of Attack * * * * * _Plate the First half an inch to a foot_, The incompressible part of this vessel in which the men are when she descends under water, is composed of cast brass cylenders 6 feet diameter and 6 feet long about one inch thick; which will be of a strength to resist the pressure of more than one hundred perpendicular feet of water; Three or more of such cylenders may be screwed together at the flanges to make a length of 18 or 24 feet; the ends forming a part of a sphere to resist the pressure of the water in all directions; The dome where the Men enter may be three feet diameter three feet high; with a smaller dome on the lid through which observations may be made when raised a foot above the water: The cylender and dome is placed in the body of an ordinary shaped vessel; and the water chambers for sinking will be round the cylender as seen in plate the second; In this place it will only be necessary to mention the different parts which compose a submarine Vessel, any person acquainted with mechanics can trace their movements and uses, _A_ The bow anchor, _B_ The plunging flyers communicating by two angle wheels to the insides; _C_ The bow cable, its windlass Slides backwards and forwards on a square axis and lays the cable in regular coils; _D_ A small safety pump to drive the water out of the balancing chest _G_; suppose this pump one inch diameter, a column of water one inch diameter and 300 feet high would weigh about 150 pounds; hence one Man with a lever of three to one; could work such a pump under a pressure of 300 feet and rendering the Vessel lighter than her volume of water, could mount from that or even a greater depth to the surface; _E_ and _F_ a pipe and cock to let the water into the balancing chest _G_; _G_ The balancing chest of a capacity to receive from three to five hundred weight of water, when the outer chambers are full, the Vessel being still from three to five hundred pounds lighter than water; Water is then let into the balancing chest correctly to such a weight that the flyers or plunging anchor can hold her under water; _H_ A air pipe to let out the Mephitic air; there is a similar one which extends to the stern, and enters a Ventilator _Q_ by which means the air may be renewed in the Vessel;
