ROUGH-AND-TUMBLE ENGINEERING 



the governor will in stop and the engine will go 



on a tear. 1 ml> nut has worked loose, the gov- 



.1 run as usual, except that it will increase its 



speed as the speed of the engine is increased. Now any 



of these little things may happen and arc likely to. None 



icm are serious, provided you take my advice and 



n near the engine. But if you arc thirty or forty 



feet away from the engine and the governor belt slips or 



gets unlaced, or the pulley gets off, about the first thing 



the engine would do would be to jump out of the belt, 



and by t you can get to it, it will be having a 



mighty lively time all alone. This might happen once 



and do no 1 1 it might happen again and do a 



great deal of damage. You are being paid to run the 



engine and you should stay by it. The governor is not a 



cult thing to handle, but it requires your attention. 



If I should drop the discussion of the governor at this 

 point you might say that I had not given you any in- 

 structions about how to regulate its speed. I really do 

 not know whether it i^ worth while to say much about 

 n, for governors are of different design and arc 

 necessarily differently arranged for regulating, but to 

 help young learners I will take the Waters governor, 

 which is found on many threshing and farm engines.

 stem two little brass nuts. The upper one is a thumb nut
