A Young Inveutor of Oslikosh Seems to llave Solved the Problem of Submarine Navigation His Craft Runs by Elec tricity and Is Easily Managed. How to sail under water has been as perplexing a problem as how to sail through the air. Alleged solutions of both havo been announced from time to time, but tho fact remains that aerial and submarine navigation are not in dulged in to any great extent. The latest inventor to claim a perfect ed submarine boat is Richard Raddatz of Oshkosh, Wis., nnd go far his achievements achievements in this line have been remark able. He has constructed a boat which has done more than any other subma nne craft ever built With one passenger passenger he has remained for three hoars tm - uer water witnout exhausting his air supply, and he has apparently demonstrated demonstrated his ability to control the movements movements of his boat with perfect ease and exact nicety. Thus far all the tests have been made in Lake Winnebago, Fox river and oth er inland waters of Wisconsin, but the boat has been shipped by rail to Mil waukee and will soon be tried in the deeper waters of Lake Michigan. The new submarine boat, which is as yet unnamed, is shaped like a long, thin cigar. It is C5 feet 10 inches in length and has a midship section of 16 feet in length which is 4 feet in diameter. At each end of this midship section rises a turret several feet high. The hull of the craft is of armor steel five sixteenths of an inch in thickness. At the apex of the tapering prow is a sharp steel beak 6 feet long, which gives it a formidable appearance. Without ballast tho boat weighs 26,000 pounds. The interior of the boat is far from commodious, as only in the turrets can a man stand erect. For submarine navigation navigation an electric motor, run by a 30 cell storage battery, furnishes tho pow - RICHARD RADDATZ. er. Besides this is a hot air engine, which burns kerosene as fuel. Both are connected with the propeller shaft by friction clutches and may bo used independently independently or jointly. The hot air engine is for use on the surface and for recharging recharging the storage battery. With the cells charged the inventor calculates that he can run under water for ten hours at the rate of ten miles an hour. On the surface he can make 14 miles an hour with decks awash and using only the hot air engine. This is a much better performance than other submarine boats havo achieved. The kerosene tank has a capacity of two barrels, which allows the craft to make a voyage of two days and a ' balf without replenishing the fuel. The propeller is a two bladed af fair which can be run at an average of 800 revolutions a minute. The principle by which the boat is steered, sunk and raised is a secret which Mr. Raddatz will not divulge. In managing the boat he sits in the front turret. Before him is the steering wheel, and about him are numerous buttons, switches and indicators. He denies that ho uses lateral fins or rudders rudders or that he guides the boat upward or downward by forcing water in or ont of a chamber. Men who have been down with him say that not only is he able to raise or lower the boat at will, but that he can run it under water on a level keel at any depth. Just how he maintains his air supply is another of Mr. Raddatz's secrets, but maintain it he does. In a general way ho says he accomplishes it bv a renewal of the oxygen by chemical action and an absorption of tho carbonic acid . gas by caustic potash, caustic soda and lime. Other inventors have tried to make air by this method, but have failed. To what use the boat will bo put has not been announced, but it is believed that it will be used in raising wrecks, as it is fitted with a hydraulic lock in the bottom through which a diver may either leave or enter the boat while un der water. Inventor Raddatz is a tall, thin young man of about 28, who has the thoughtful face of student and the grimy hands of a mechanic. He was born in Oshkosh and is a graduate of the Wisconsin normal school. By trade he is a machinist, and at present is employed employed as a mechanical draftsman in the Allis Machine works, Milwaukee. Fi7B years ago he read that tbe French government had offered a big reward to the inventor of a successful submarine boat, and since then he has been experimenting. experimenting. His first attempt resulted in the construction of a crude wooden at fair with side wheels, but it served to convince him that he had the right idea of submarine navigation, and through mauy discouragements and failures he kept quietly pegging away until he emerged from his seclusion to startle the country with a submarine - craft which will actually work while sub merged.
