 the cylinder sheller is shown in Fig. 173, and is described 

 by the manufacturer as follows: "The shelling cylinder

 smooth. Within this a revolving iron cylinder with 

 spiral vanes threshes the corn against the surfaces of the 

 rod cylinder. The vanes approach the rods sufficiently

 operator. The spaces between the rods allow the shelled 

 corn to escape freely, thus lessening the draft, relieving 

 the cylinder from clogging and from all liability to cut or
