FITTING UP AND STARTING A NEW SEPARATOR. 123 

 * 



not under tightener* (see cut page 1 70), and the shoe belt 

 may be now run on. Oil the moving parts as they run, 

 occasionally screwing down the grease plugs on crank- and 

 fan-shaft boxes. The chain of the tailings elevator should 

 be adjusted so that it has slack enough to turn freely, but 

 not enough to allow it to kink or unhook. After oiling the 

 upper boxes and both bearings of the tailings auger and the 

 four of the tailings conveyor, run on the elevator belt, which 

 drives from the crank, crossed, (see cut page 128). Oil the 

 bearings of the grain auger and put on its belt. Where no 

 grain elevator is used, this belt will go on either side of the 

 machine, so that it may always be on' the opposite side to 

 that from which the grain is taken. 



When all parts of the separator are in motion the bear- 

 ings should be carefully watched to detect any tendency to 

 heat, and this can best be done when the machine is running 

 empty, for the operator can then give it his entire attention. 

 The machine has been tested and left the factory in good 

 running order, but dirt and grit of shipment by rail is liable 

 to cause trouble and it is best to make sure that all the bear- 

 ings are oiled. It is of great importance tHat these bearings 

 be well oiled on the first run, as they are somewhat rough, 

 and consequently require more oil and a longer time for it 

 to spread over the journals. Oiling a shaft as it runs, allows 

 the oil to work in and be distributed over the whole bearing 

 surface. 



When the machine has run for an hour or so and every-
