A combined husker and shredder patented by J. F. Hurd, of Minnesota, in 1890, appli- cation having been filed in 1887, is one of the earliest of the shredder type. There are at this time many different makes of this machine in the market. They are of various designs and are frequently made so as to be fitted with exchangeable cutter and shredder heads. The general construction of all machines of this class is very much the same, however. Some are rather complicated in their construction f>A/£UMja TIC Sr^KM'^'/f. Fig. 22.—Skeleton of husker and shredder. while others are very elementary. A discussion of one of the more complicated will serve to explain the general operation of all. By referring to figure 22 the construction will be easily understood. The stalks are first fed to the snapping rolls, where the ears are broken from them. The stalks are driven forward by the snapping rolls until they meet the shredder head, where they are cut to shreds by knives of special forms shown in figure 23. The slu'edded parts of the stalk fall upon a vibrating carrier whose motion is comple- mented by the action of arms. The shreds fall from this carrier into the blast from the fodder blower, which carries them up tlii'u the stacker. The ears which are broken from the stalks by the snapping rolls drop upon the husking rolls where the husks are torn from them. The husked ears gradually descend along the inclined huskmg rolls until they finally fall upon an elevator which carries them to the bin
