178 SCIENCE OF SUCCESSFUL THRESHING. 



' The Attached Stacker. This is the name given to the 

 automatically swinging stacker which is attached to the 

 separator. The present style has an upright-section, to the 

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

 pivot-point about ten feet from the ground, and since the 

 carrier is this distance from the ground when level, its outer 

 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 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 cen- 

 ter of the shaft. All the other shaft bearings are provided 

 with oil-cups which should be partly filled with a little wool 

 or cotton-waste. 



Independent Stackers. This is the name given to swing- 

 ing 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
