IQ4 SCIENCE OF SUCCESSFUL THRESHING 



der to the acre. For this reason, the twenty-eight by forty- 

 six and larger sizes of separators are more suitable than 

 the smaller ones. 



Special Cylinders for Peas and Beans. There are local- 

 ities in which a separator may be kept constantly threshing 

 peas or beans for several days or even weeks at a time. 

 For such machines, it is often advisable to obtain a special 

 cylinder with the teeth spaced for this work. When so 

 equipped, a "Case" separator will do better work than it 

 would do with the regular cylinder. In fact, its work is 

 then equal to that of the machines designed especially for 

 hulling beans, while its capacity is much greater. In 

 changing to the special cylinder, it is necessary to procure 

 the special concaves and concave-circles, as well as the 

 cylinder. 



FOR PEA AND BEAN 12-BAR SEPARATORS (BELT): 



6063T Main Cylinder Pulley, 18" dia. (regular pulley may remain 

 on), runs cylinder 425 r. p. m. when 36" engine fly-wheel 

 makes 213. 



5066T (6" face) or 5067T (4" face) Cylinder Pulley drives beater 

 and crank, 15" dia. (remove tightener), runs crank about 

 normal spe'ed, 230 r. p. m. with cylinder speed of 425. 



B5068T Cylinder Pulley drives feeder, 17" dia., runs feeder-crank 

 258 r. p. m. with cylinder speed of 425. 



A5065T Cylinder Pulley drives wind stacker, 20" dia., runs jack- 

 shaft about 687 r. p. m. with cylinder speed of 425. (Nor- 

 mal, 760.) For lower cylinder speed or faster stacker 

 speeds, use pulleys A303H or B303H on jack shaft. 



FOR PEA AND BEAN 12-BAR SEPARATORS (GEARED) : 



5071T Bevel Gear (47 teeth) and Cylinder Pinion A5072T (Steel), 

 or 5072T (Wood) (25 teeth), run cylinder about 425 r. p. 

 m. with the normal tumbling-rod speed of 227 r. p. m. 

 For lower cylinder speed, larger spur-plnlons may be 

 used on the horse-power. No special gears are made for 

 20-bar separators. Pulleys, except 5063T, same as for 

 Belt separators for Peas and Beans. 



FOR PEA AND BEAN 20-BAR SEPARATORS (BELT): 



5372T Main Cylinder Pulley, 26" dia., runs cylinder 290 r. p. m. 

 when 40" engine ny-wheel makes about 190.
