Richard's corn siieller. 19i> 



cylinder, with chilled teeth, thrashes the corn against the 

 surfaces of the rod cylinder. The teeth approach the 

 rods sufficiently close to keep every ear in rapid motion, 

 shelling one ear or one bushel with the same facility. A 

 regulator at the discharge end places the machine within 

 control of the operator. The spaces between the rods 

 allow the shelled corn to escape freely, thus lessening the 

 draught, relieving the cylinder from clogging and from all 

 liability to cut or grind the grain. 



The cleaner consists of a cylindrical screen revolving 

 around the whole length of the sheller, and extending be- 

 yond it. A heavy fan blast passes directly through this 

 screen, and under it, subjecting the corn to two separate 

 cleanings, and delivering it in good condition for market. 

 The cleaned corn discharges upon either side desired, and 

 the cobs are delivered with the dust at the end of the ma- 

 chine.
