As the position of the bell-crank H is controlled by the governor, any change inthe height of the governor will cause a change in the position of the point/, and a correspond-ing change in the time of release. The action of the automatic safety-stop motion is illus-trated by Figs. 53 and 55. Fig. 53 shows the position of the various parts when the engineis at its lowest normal speed, and the hook E is at the point of engagement with the valve-lever B. The lower side of the link O is provided with an adjustable embossment u\ which, inthe position shown, is just clear from the hub of the bell-crank i/1 Now, should the governor-.
