2) The product leaving the machine is put up automatically in a

3) The machine is full)" equal to other winnowers in yield, but fur-

 in turn transmits it to the screens through the elbow-joint and the con- 

 necting rod e f] and to the fan through the pulleys P, P' and the belt. 



The material contained in the hopper T falls on the ist screen A, which 

 is a cast iron plate, suspended to the frame by the springs r and the 2 arm 

 levers h, one being short for the purpose of regulating the .screen angle, and
