Show Fuel Oil for Use on the Rolling Ships Can Now Be Stored Aboard Large Vessels Oil has been poured on raging seas to calm turbulent waves which threaten shipwreck. Now comes Edward Ed-ward R. Carroll of Brooklyn, N. Y., with an invention which is intended to do the same thing, but keeps the oil in the ship's tanks, notes a writer writ-er in the Kansas City Star. The invention provides an ingenious ingeni-ous control of the swishing of the oil inside the tanks, which counteracts counter-acts pitching and rolling of the ship. Used on battleships, it would keep the ship steady so that the aim of its guns would not be spoiled. Carroll's invention, described in a patent (No. 2077143) recently granted grant-ed to him, is designed for ships with engines that burn oil for fuel, such as Diesel engines. The ships would be provided with a double bottom and wing tanks built in the sides. In these the oil is stored. Unlike conventional storage tanks, these tanks and the double bottom are divided up into long cells by iron plate-like partitions. Valves in the partitions can be controlled from a central station. By opening and closing the valves, flow of oil from one cell to the other is controlled. con-trolled. Whenever the ship begins to roll, the valves distribute the flow of oil so as to act as a counterweight to the roll. Thus, when the ship tips to starboard, all the oil cannot move instantly toward that side. It is held on the portside and helps to right the ship. Similarly any synchronism between be-tween waves and motion of the ship which leads to violent rolling would be broken up. Such synchronism increases the roll to the point where it endangers the ship. It is brought about by the same principle involved in-volved in swinging. Just as a slight push at the proper moment sends the person in the swing higher into the air, so waves in synchronism with the roll of the ship, can cause it to roll and pitch more and more steeply. |
