234 SCIENCE OF SUCCESSFUL THRESHING 



the upper end of which the outer carrier is attached. This 

 brings the pivot-point about ten feet from the ground, 

 and since the outer carrier is this distance from the ground 

 when level, its end does not perceptibly draw away from 

 the stack as it is elevated. 



Operating the Attached-Stacker. The carrier of this 

 stacker may be made to swing automatically, and, as is 

 the case with other self-swinging stackers, the length or 

 arc of swing depends upon the position of the trip-pins. 

 Many stack builders prefer to swing the carrier by hand 

 from the stack. This may be done by disengaging the 

 driving apparatus. The carrier of this stacker should 

 always be folded so as to rest on the deck of the separator, 

 before the machine is moved from place to place. 



Oiling the Attached-Stacker. All of the gearing 

 should be frequently greased, especially the bevel-gears 

 and the worm-gears. The upright bearing is oiled through 

 the center of the shaft. All the other shaft bearings are 

 provided with oil-cups which should be partly rilled with 

 a little wool or cotton-waste and oiled regularly. 



Independent Stackers. This is the name given to 

 swinging stackers which are mounted on trucks separately 

 from those of the separator. The independent stacker was 

 quite universally popular at one time. Of late years the 

 wind and other swinging stackers have replaced it very 

 generally. 



The Wind Stacker has steadily increased in popularity
