THE IRRIGATION AGE. 



Chicago Improved Cube Mixer Used on a 

 Dam Across Rock River at Milan, 111. 



This is what the contractors, the Gould Construction Co., 

 Davenport, Iowa, had to say about it: 



"Chicago Improved Cube Mixer No. 11, hold- 

 ing 11 cu. ft. of mixed material, was placed on 

 the false work of dam, 23 ft. from the ground, 

 with elevator extended to the ground level, where 

 the cement, sand and gravel were deposited 

 directly into the charging hopper, which in turn 

 delivered the material directly into the mixer, 

 and from the mixer it was delivered to the forms. 



"The work consisted of 31 sections, each 15 

 ft. long, and was completed in 31 days. The 

 arrangement for placing the mixer was very 

 satisfactory, and we were not delayed for one 

 moment for any cause as far as the mixer was 

 concerned, and we have mixed as high as 80 

 batches per hour." 



The Chicago Improved Cube 

 is charged in batch units and the 

 batch never chokes, because there 

 are no inside shelves or vanes to 

 dam back its free flow. 



It discharges by tilting, just as 

 one in a hurry would empty a 

 bucket, by tipping it bottom up, 

 not bailing it out with a cup. 



It mixes the most uniform con- 

 crete that can be mixed, because: 

 (1) It mixes by kneading as a ce- 

 ment tester mixes cement paste 

 for test briquettes. (2) Every 

 mixing motion acts on the whole 

 batch and is definite and invariable 

 in action and periodicity.
