November, 1920 washer close to G so that if in his absence any accident should happen to the propeller or shaft, G will engage F and cause the throttle to remain closed yntil F is released by the engineer. In addition to the anticipating valve, the main governor is fitted with an emergency governor, which is designed to provide against racing due to cer- tain short following seas as well as accidents, such as broken shafts and lost propellers. It will cause the throttle to close immediately on the slightest ac- celeration of speed from any cause. It consists of a weight-lever W bound by an adjusting spring to another lever moving to and fro at the same speed as the engine. is revolving, in front of a cock between the condenser and re- lay. cylinder. The second lever is connected to the main engine suitably to give it a recipro- cating stroke of 4 inches. This connec- tion is most frequently made with the indicator gear or in some instances with the air pump beam. When the engine is running at its predetermined speed, the weight-lever oscillates be- tween the two projections, H and J, with the minimum of clearance without touching them. In that action the valve, of which these two projections are on the arms, is just closed. Immediately the speed should be increased by 1 per cent or more. The increased momentum thus given to the weight-lever causes it to strike one of the projections H and J, thereby opening the valve and creating a vacuum below the relay piston and causing the same action as in the case of the anticipating valve. The governor is supplied in two parts, THE MARINE REVIEW the control panel to be bolted to an en- gine column and the throttle operating cylinder fixed in proximity to the throt- tle valve. The two are joined together by two pipes and the control panel is connected by a pipe with the condenser.
