Oprrinfrinn 



Silos are built of reinforced concrete blocks 

 made in Hurst Patent Molds using the poured 

 The Silo system. The Blocks are 23% inches long, 11% 

 inches high and 4 inches thick; are dense, water- 

 proof and have tremendous crushing resistance. Each block has 

 running through it two steel rods % inches thick. These rods 

 have their ends out turned at right angles in recesses in the ends 



of the block, as' shown in Figure 3, 

 No. 10. They are curved to form a 

 perfect circle in any desired circum- 

 ference. 



The blocks are laid in cement 

 mortar same as any building block. 

 The only difference is in the rein- 

 forcing and locking device. Each 

 circle of blocks when laid in the 

 wall forms a circular chain of which 

 each block with its reinforcement is 

 the long link. When blocks are set 

 steel links are placed over the ends 

 of the reinforcing bars, tension ap- 

 plied and then filled with cement. 

 (See Figure 3, No. 10, and Figure 2.) 



In the above manner Hurst Silos 

 are erected. For closer detail see 

 Figure 3. When walls are complete, 

 a plaster i/4-inch thick of one part 

 cement, two parts sand, one-fifth 

 hydrated lime is applied, making a 

 smooth, waterproof interior, which 

 insures perfect settling and keeping 

 of ensilage.
