Scientific American Volume 78 Number 03 (January 1898) . LONGITUDINAL SECTION AND PLAN OF THE QUEEN SHOWING ENGINES C, CENTRIFUGAL PUMP B THE DELIVERY PIPES FOR THE HYDRAULIC JETS. SUCTION A. AND. HYDRAULIC LIFEBOAT THE QUEEN CONSTRUCTED FOR THE ROYAL NATIONAL LIFEBOAT INSTITUTION theItintothe Thistle andAmerica built entirely of steel and is fully subdividedwatertight compartments. In the after part ofboat is a large open cockpit, from which the steering isdone. The cockpit is made watertight with non-returnrelieving valves, which allow any water which may beshipped to flow out immediately. The rudder projectsconsiderably below the bottom of the boat to enable itto take hold of the water in a choppy sea. The steer-ing is greatly assisted by the method of hydraulic pro-pulsion, as will be explained later in the article. The boat is driven by engines, 0, of 200 horse power,which are direct connected to a centrifugal pump, B,which is placed approximately horizontally near thebottom of the boat. The pump is 2 feet 6 inches in dia-meter, and, when running at full speed, it makes 450revolutions per minute. The cylinders of the com- be directed either toward the bow or the ste
