THOROUGHNESS 



Concrete in Silo Construction MUST be Thoroughly Mixed. 



The Blystone Shovels, which insure absolutely perfect 

 mixing of concrete or mortar. Handle dry or wet, coarse 

 or fine material. 



The open drum enables 

 the whole mixing opera- 

 tion to be watched and 

 controlled. Extremely easy 

 to clean. No attachments 

 to eat up power and get 

 out of order. Every ounce 

 of power mixes. 



Hopper & Son, Manhat- 

 tan, Kansas, say: "We 



now have in use five of 

 your mixers building silos. 

 We find it a very conven- 

 ient mixer for this pur- 

 pose. We are especially 

 concerned in a thorough 

 mix, light weight for trans- 

 portation and moderate 

 price. In all these re- 

 spects your machine fills 

 the bill."
