DESEEDING METHODS

5, 6, 7, and 8 are shown. Each reel contains six steel blades, 9 

 and 10, about 3 ft. long, 2 ft. broad and A in. thick, and are 

 rounded at the tips. These blades are compounded with the 

 discs 3 to 8, and consequently rotate with the shafts 1 and 2. 



The function of the reels is to remove the seed bolls by means 

 of the rapid rotating steel blades, which are adjusted to inter- 

 sect but traverse the same horizontal plane. 11 and 12 is a 

 pair of slightly fluted and slow revolving rollers, the speed of

the latter being twice that of the former. Their work is to 

 break the deseeded bolls and liberate the seed, which opera- 

 tion is assisted by the rubbing effect generated by the varying 

 speed of the two rollers. 



The straw is selected in handfuls off the table 13, and passed 

 over it, into and between the rapidly rotating steel blades of 

 the reels 1 and 2. The lower reel, rotating counter clockwise, 

 removes the bolls from the underside, and the upper reel,
