E (Cl. 30H7) s This invention relates to a new and improved ensilage blower and has for one of its principal objects the provision of `means for feeding en silage to a blower. traveling in axial alinement with the fan axis shaft 22. In the instantensilage blower, the feed auger l@ lies parallel to a plane described by the path of travel of the fan I'I. Or, in other words, , Heretofore, ensilage blowers have usually em 5 vthe auger I8 is at right angles to the fan shaft 22. ployed some type of feed conveyer positioned at The auger I8 is mounted within a housing 23, right angles to a plane described by the path the upper portion of which is expanded to form of a blower fan.

Another important object of this invention is to provide a novel feed device for ensilage blow ers which tends to prevent congestion of the en 15 edges of the flight 3l of the auger I8. This cut od contributes to the successful feeding of the auger. The housing 23 is joined to the fan hous-l ing 2li by means of an elbow-like conduit 26 which is best shown in Figure 2. silage as it is fed into a blower'. In operation, ensilage is put into the hopper 2t through its large opening 25 whereupon the auger it, rotating in the direction indicated by the ar .
