THE ENGINE PROPER 73 



The outward movement of the balls is resisted by springs. 

 A perspective view of a governor is shown in Fig. 20, and 

 a sectional view of the valve-body in Fig. 21. The valve 

 connection to the stem has no play endwise, but is flexible, 

 thus allowing the valve to align itself by its seat. 



Speed of Engine. To increase the speed of the engine,

 stuffing-box down too hard on the packing, or the sensi- 

 tive action of the governor will be interfered with. It is well 

 to allow a slight leakage to insure its not being too tight. 



Oiling the Governor. Oil the governor thoroughly 

 with good oil. Oil regularly (at least twice a day) the 

 brass washer at the top, the horizontal shaft, the barrel 

 (which is oiled from the top), etc. Keep the governor 

 clean and oil-holes open. If oil has been used which gums 

 or causes the parts to stick, a little kerosene poured into 

 the oil holes will clean the parts. If the use of gummy 

 oil is continued, this treatment should be repeated once 

 a week after shutting down. 



The Governor Belt. Use a thin flat belt and see that 

 the lacing or fastening is hammered down flat, so that no
