THE MARINE ENGINEER AND NAVAL ARCHITECT. 93 ANDREWS PATENT GOVERNOR. THE governing of a marine engine is .1 subjei 1which has interested generations of enginiIt has afforded hundreds of inventors a problemof great difficulty to solve, and the world as a resultis presented with a large number of devices designedto effect the purpose, but with very varying success. It is not certain whethei shipowners, who are reallymore interested in this question than other people,quite fully appreciate the importance of a really effi-cient governor for marine engines. The result ofracing is strained engines, broken shafts and looseseats. The flaw in a shaft is no doubt often startedby some abnormal strain, and its extension is onlya question of a certain number of impulses beforefinal fracture takes place. For example, a flaw may. Fig. 1. 94 THE MARINE ENGINEER AND NAVAL ARCHITECT October i, 1907. be started in heavy weather, while the shaft finallyfractures months afterwards during ordinary conditions,hence to prevent abnormal strains in the machineryeffective governing is of immense value to the ship-owner, as apart from the expense of installing a newshaft, the loss of earning capacity by the ship lyingup is a serious item. \?? 1 hen on a voyage il the governing of the engines can be absolutely and auto-matically controlled in a reliable manner within safelimits, much better speed can be maintained, and thesaving in coal and time thus effected carries with it Road, Deptford, in the direction of the provision ofapparatus of a simple and reliable character whichwill govern a marine engine and prevent racing,either from the submergence of the propeller beingvaried or from other causes, which may relieve theengine of a part or the whole of the resistanceagainst turning.
