Simon Lake submarine patent

In 1897, a U.S. patent was issused for a "Submarine Vessel" invented by Simon Lake (No. 581,213). It described oscillatory lateral vanes on the sides of the vessel to set for ascending or descending, a weight to shift fore-and-aft to keep the vessel on an even keel, a compressed air reservoir, ballast tanks, an "air-tight diver's chamber provided at the bottom with a trap" (suitable for diving salvage operations), and wheels to travel on the water-bed which could be propelled and steered from within. Lake was interested in the use of a submarine for commercial, rather than military, purposes. It had a hinged observation tube, which could be provided with a mirror (forerunner of the perioscope). It was expected to be steam-powered on the surface (but in practice the heat generated by the boiler was intolerable to a crew, and thus impracticable.)«[Image: rear view of submarine, showing hull with lateral vanes, wheels and propeller.]
