The husks fall upon a conveyor chain which drags them hack to the 

 fodder hlower, where they join the slu-edsfrom the stalk. The loose 

 grain falls from the vibrating carrier and husk conveyor upon a screen. 

 As it falls it is met by a mild blast which removes the dwst from it. 

 This grain is then collected in a trough or chute and is driven by means 

 of a screw conveyor to one side of the machine. 



This machine combines in its construction many elements used in 

 earlier machines, both buskers and fodder cutters. The snapping 

 rolls and husking pegs are both ideas found in machines described in 

 preceding paragrai)hs, while the shi-edder heads are not greatly dif- 

 ferent from those of the fodder cutters of earlier design. The blower

and cleaning and carrying devices are very much like those of the 

 thrasher. Self-feeding and safety devices are now largely used as a 

 protection against the danger of having one's hand or arm caught in 

 the mechanism (fig. 24). Where the self-feeder is used, a revolving 

 band cutter is commonly placed a little ahead of the snapping rolls.- 

 The superior convenience of having the stalks bound into bundles 

 is most evident where these machines are used. In bundles the 

 stalks keep straight and thus avoid the delay caused by having them 

 come to the machine in a disordered condition. There is also less 

 danger of choking the machine. Plate IV shows a busker and slired- 

 der run bv a gasoline engine.
