These objects have been satisfactorily accomplished in the following 
manner : — A is the feed-board radiating on pivots B. F is the hood radi- 
ating on pivots G. C and E are levers secured to the ends of pivots B 
and G. These levers are connected through the medium of the rod D, conse- 
quently any slight pressure or weight brought to bear on the hood F or feed- 
board A instantly closes the mouth of the drum ; the hood then resting on 
the top of the machine-frame, as shown in Fig. 2. The coupling-rod gives 
simultaneous movement to the feed-board A and hood F. A convenient 
opening is left below the bottom edge of the hood (whether up or down) for 
weeping loose corn into the drum, which, coupled with the compact method 
f construction, renders it a valuable adjunct to threshing-machines.
