THRESHING WITH SPECIALLY EQUIPPED SEPARATOR 201 



badly shelled in handling so that the amount threshed will 

 be considerably less than the actual yield would be, were 

 it possible to save it all. 



The adjustable-sieves should be set well closed for tim- 

 othy and a lower sieve must be used to get the seed clean. 

 Either the one-sixteenth-inch round-hole sieve, M, or the 

 sixteen by sixteen-mesh wire sieve, T, are suitable for tim- 

 othy seed, and either may be used successfully, if placed in 

 the seventh notch and fourth or fifth hole. When common- 

 sieves are used, the three-quarter-inch lip-sieve, F, will be 

 found to be the most suitable for a chaffer and the three- 

 eighth-inch lip, G, is an excellent upper sieve for the shoe. 



Threshing Orchard-Grass. In threshing this grass, 

 the cylinder should be run at its regular speed, and six rows 

 of concave teeth, set well up, should be used. Good work 

 has been done with the adjustable sieves alone, but as a 

 rule, the seed can be cleaned better by using the three- 

 thirty-seconds by one-half-inch oblong-hole special sieve, 

 U, underneath the adjustable shoe-sieve. It should be 

 placed in the seventh or eighth notch and sixth hole. The 

 adjustable shoe-sieve should be placed in the second notch 

 and third hole. If common-sieves be used, place the one 

 and one-quarter-inch lip sieve, E, in the conveyor. Use 

 the three-quarter-inch lip sieve, F, as an upper sieve in the 

 shoe placed in the first notch and third hole. Use the three- 

 thirty-seconds by one-half-inch special orchard-grass sieve, 

 U, below, placing it in the same position as when used 

 with the adjustable one. Since the seed is light, but little
