Show A NOVEL SUBMARINE NEW TYPE OF UNDER WATERCRAFT WATER-CRAFT INVENTED BY NEGRO Problem Solved If Principles WorkOut Work-Out as Well as In Trial Boat Will Bt of Great Service as Life Preserver I Denver Robert Lincoln a negro Inventor In-ventor of this city has perfected an entirely now typo of submarine craft which Is to be brought to tho attention atten-tion of the war department by a num bar of capitalists who have become interested In-terested tho Invention If Lincolns principles work out as well In tho trial boat as they do in tho model there is no doubt that he has solved the problem of under water navigation naviga-tion lie gives the following details concerning his unique craft My Invention will not only prove an Improvement in submarine navigation naviga-tion but will Introduce a now mode of propulsion which may ho applied to nil water craft whether running on or beneath tho surface of tho water Uio Inventor says It can bo steered or controlled with as much case and safety In rough as In calm seas Observation can betaken be-taken as accurately while tho boat Is wholly submorged as when on tho surface sur-face by a system of mirrors and refracted re-fracted rays only exposing an eight Inch pipe to view The boat Is agile swift and durable It will stand tho pressure of the water at any depth Oy tho application appli-cation of hydroplanes keel and turrets tur-rets we are able to do away with tho propeller and its ponderous machinery absolutely necessary to get speed from tho style now In vogue The revoluble hull Is tho greatest achievement of the Invention It has a spiral arranged blade encircling It from end to end resembling a corkscrew cork-screw When this hull Is sot In motion mo-tion upon its axis this blade coming + C Lrr Y Model of New Submarine In contact with a great surface of water wa-ter tho forward movement of the boat is smooth Tho Inner bout being carried by tho outer boat does not come in contact con-tact with the water and can offer no resistance to its speed or momentum The Inner boat is similar in con struction and size to tho outer and constitutes the living apartments and affording place to carry nil tho necessary neces-sary appliances according to tho usage of tho boat At a suitable distance from each end of the Inner boat two turrets are constructed that rlso at right angles to the inner boat to a distance of a foot above the greatest diameter of tho re volublo hull So that when running awash only a very small portion of tho boat Is exposed to view and no vital parts Tho rear turrets constitute a pilot house and also afford an open lag for ingress and egress to the inner boat tho pilot house being telescoped In the turret and closed with watertight water-tight fastenings when boat is submerged sub-merged Tho lower ends of tho turrets are made flat and thin and extend downward down-ward to a point sufllclent to hold a solid iron keel which allows the re voluble hull to turn between it and the Inner boat This keel steadies tho boat latterly and adds stability to the Inner boat being rigidly connected at both ends If in tho rapid rotation of the outer shell tho inner boat may have any Inclination In-clination to deviate from a level by working tho hydroplanes of the one side adverse to those of tho other their action on tho wntvr will easily and effectively arrest such deviations From both ends of the Inner boat there is a conical prow extending and coming to a point which makes a most Formidable weapon and can effectively I bo used In ramming other vessels tln these prows und In front of the forward for-ward turret and rear of the rear turret tur-ret are torpedo tubes using compress com-press d air force While the boat has been recommended recom-mended for war purposes its greatest service to mankind will bo as a life preserver All parts and appliances of this boat aro made and put together from tho Inside so that the boat can be repaired re-paired at sea as wcJJ as In dry dock |
