SCIENCE OF SUCCESSFUL THRESHING. 



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

 remains tp cause an uneven working of the governor. 

 The belt should be sufficiently taut to prevent slipping, 



but not so taut as to 

 cause undue friction. 



If the governor 

 "jumps" or is irregular, 

 it is probably occasioned 

 by one of the following 

 causes : first, because the 

 valve is a little tight ; 

 second, because the valve 

 stem is bent; or third, 

 because the stuffing-box 



nut is screwed down 

 VALVE too tightly. Turning the 



valve stem up and down, while the governor is running, 

 will show whether the valve works freely in its seat. If it 

 binds at all, take it out, and rub it with fine emery cloth, 

 but never attempt to file it. In taking the governor apart, 

 the top must be lifted off as "true" as possible, so as not to 

 bend the valve stem. If the valve stem becomes bent where 

 it passes through the stuffing-box, it will be best to procure 

 a new stem.
