230 SCIENCE OF SUCCESSFUL THRESHING 



The other bearings also need to be oiled several times a 

 day. The friction band of governor should not be oiled 

 after it becomes smooth. 



The Speed Governor drives the feeder by means of 

 a friction band, which is clamped over a friction pulley, 

 by means of the centrifugal action of the weights. The 

 spring tension on these weights should be such that the 

 feeder will not start until cylinder is very near its normal 

 speed. In starting a new feeder any paint that may be 

 on the face of the friction pulley should be carefully re- 

 moved and the surface scoured with emery-cloth or fine 

 sand-paper until smooth and bright. A very little oil may 

 be used the first few days, but when once properly adjusted, 

 it will not require any further lubrication. The best 

 adjustment of the governor will be found to be as fol- 

 lows: First adjust the friction band so that the weight 

 arms may be pulled out about half way by hand. Then 

 set the weights about one-half inch from the ends of the 

 arms and give the spring but little tension when the 

 weights are in and the band is loose. The final adjust- 

 ment of the spring can best be made by trying it and 

 setting it to suit the speed. Wrench 5548T will be found 

 convenient in adjusting the spring. 



The Straw Governor should be adjusted by the oper- 

 ator to suit the rate of threshing and the requirements of 

 the grain. This is done by means of the thumb nut at the 

 top of the feeder, on right-hand side, screwing it up for
