DEERE IMPLEMENT COMPANY 



Grant's Fan-Mill. 



Double Blast. 

 ESPECIALLY RECOMMENDED FOR CLEANING BEANS. 



The blast is divided into these two distinct currents by a board which is denomi- 

 nated a chess board, which is arranged immediately under the screen, and which ex- 

 tends from the points of the fans to that part of the under edge of the screen over which 

 the grain falls in that thin, unbroken sheet, of which we have spoken. This board 

 serves the double purpose of dividing and of receiving the particles falling through the 

 screen, as well as preserving the under side of the screen from the action of the wind, 

 which might retard or partially prevent the falling of these particles through its meshes. 



In all other Fanning Machines the grain falls directly from the hopper to the dis- 

 charge board, and however well cleaned of its chaff, it has not been screened ; whereas 

 in the GRANT WINNOWERS the grain is first operated upon as in the ordinary machines, 

 and then falls through a second and stronger blast of wind, and is thus cleaned in the 

 best manner. 



Thus we see that in these excellent machines the grain is subjected to three distinct 

 actions, viz. : 



First. It is thoroughly chaffed. 



Second. It is screened from all smaller and weightier impurities. . 



Third. It is cleaned from all false kernels. 



Fourth. If there is any grass seed in the grain it will pass into the screen box, (and 

 not be lost in the chaff. The greatest care is taken in the selection of the material, 

 both wood and iron, for their manufacture, and none but the most experienced and 

 first-class workmen are employed upon their construction.
