Shaft governors, centrifugal and inertia; simple methods for the adjustment of all classes of shaft governors . ss of the second group described inChapter I.

Thisweight is pocketed for shot to admit of changes bytaking away or adding to the weight. The weightand arm are in one piece, pivoted by the pin E, Theend of the weight-arm is connected to the eccentricdisk by the link F, The spring G is made fast to theweight-arm by the band H, The adjustment of thespring-tension is obtained at the point / by slackingor screwing up the binding bolt K, To increase the speed of the engine, increase the ten-sion of the spring, or decrease the weight, or both. To decrease the engine-speed, decrease the spring-tension, or increase the weight, or both. Bear in mind that if the proper sensitiveness hasbeen reached and only the speed is to be changed,the change should be made in the weight alone. // the governor is sluggish, first see that everything 67 68 SHAFT GOVERNORS. STRAIGHT-LINE ENGINE GOVERNOR 69 relating to the valve-motion is free; then, if still slug-gish, add more spring-tension and more shot in theweight pocket. // the governor races, it may be due to sticking insome of the joints or in the valve-rod; if these are free,decrease the spring-tension and take away shot fromthe weight. VI IDEAL ENGINE GOVERNORS The a. L. Ide and Sons Co. use the Rites InertiaGovernor on the engines they now put out, and havedone so for some time past. Chapter III of thisbook, with the remarks here given, covers all thereis to be said in reference to the adjustment of thesegovernors. The Ide Company has made an improvement inthe Rites governor in the shape of a revolvable bronzebushing shown at A (Fig. i6). Owing to the factthat great wear comes on this pin, this bushing isplaced there, so that a new surface can be turned tothe wearing side of the pin
