dinary stove pipe is frequently used. Another advantage in bulk delivery 

 lies in the elimination of the handling and emptying of 100-pound bags. 



Figures 3 and 4 show some of the simpler ways to utilize gravity flow. 

 These exclude farm installations of elevators and horizontal conveyors. 

 Some of the first arrangements shown can be adapted equally well to bagged 

 or bulk feed; some of the later ones are probably better adapted to bulk 

 unloading. 



Installations for Handling Bulk Feed. 



Some diagrams of installations for handling bulk feed are shown in 

 Figures 5 and 6. With smaller units, bulk feed could be handled by gravity 

 flow on one or more floors and scooping or dipping on the top floor. The 

 second stage of complexity might occur where gravity flow is utilized to fill 

 carriers and automatic feeders. These two groups are illustrated in Figures 

 3 and 4. The installations in Figures 5 and 6 were designed for handling 

 bulk feed unloaded by the auger-type equipment at larger installations, in- 

 cluding for the largest plants, elevators and horizontal conveyors. Where 

 the plant is serviced by the pneumatic-type equipment, similar results could 

 be accomplished by a system of pipes between bins and the outside of the 

 building. Feed could thus be blown to desired points without auxiliary 

 equipment on the farm. 



A practical point to note in considering delivery by auger-type vs. 

 pneumatic-type is that in the event of breakdowns of delivery equipment, it 

 is not possible to substitute one type for another. The auger-type cannot 

 reach bins at removed points; the pneumatic-type requires a system which 

 is more nearly airtight to prevent feed from being blown out of the storage 

 bins and to prevent dust danger. The choice between the two systems, aside 

 from what the feed dealer may offer as service, may be determined by the 

 presence or absence of serviceable auxiliary equipment in the farm. 



Incorporating Existing Equipment When Shifting to Bulk Feed. 



Likewise, in considering conversion from bagged to bulk feed, the 

 farm operator may wish initially to incorporate existing equipment into the 

 new system. Figure 7 shows two examples of the changeover from bagged 

 to bulk feed. In the first example the overhead bulk bin was substituted for 

 the first floor grain room, the carrier then being filled by gravity. Elimina- 

 tion of the first floor grain room released space for other uses. Next, an 

 automatic feeder was installed, and this was so placed that it could be 

 filled by gravity. 



The second existing situation involved a third floor grain room where 

 bags were emptied into bins, with the second and first floor bins filled by 

 gravity. Fourth floor bins were filled by means of a belt elevator from the 

 third floor. This layout could readily be adapted to bulk feed, filling either 

 carriers or automatic feeders by gravity. If third floor bins could be filled 

 directly from the bulk delivery truck, downspouts could service the first 

 and second floors, either using automatic feeders on each floor or one on 

 either floor with a line running to the other floor. The fourth floor could be 

 serviced by retaining the belt elevator or by using automatic feeders on the 

 third floor with lines running up to the fourth floor.
