sieve may be placed at the fan end of the shoe, and they 

 are numbered, beginning at the top. It also shows the six 

 positions for the rod at the rear end and these are also 

 numbered from the top. 



To Insert Common Sieves place a long rod in the bot- 

 tom of slots, leaving nuts loose. The rods at fan end of 

 sieve are about i l / 2 inches longer than those at rear end. 

 In changing from one sieve to another it is not necessary

a short rod in the proper hole at rear. Adjust sieve to 

 proper position at front end and tighten the nuts. If two 

 sieves are to be used put the top one in first with rod in 

 bottom of the slots. Raise it up to proper position, then 

 put rod for lower sieve in the slots and slide it in below the 

 other. The rod of upper sieve cannot be tightened until 

 lower sieve is in place. Insert pins in the holes to hold it 

 up while putting in lower sieve. Screw the nuts up quite 

 tightly, but not so much as to cause the sieves to buckle.
