Maginnis Standard Galvanized Steel Irrigation Flumes 



Patented 

 January 19, 1904 



Patent No. 749871

 Experiment 



Maginnis Flumes have stood the test for 

 eleven years without replacing a single 

 section. Why? Because they are made on 

 "scientific principles." 

 The inner binder (which is part of the splice on the Maginnis flume) is made to 

 check a silt in the bottom of the flume which protects the galvanizing. Without gal- 

 vanizing a metal sheet will not last any longer than a stovepipe would if out in all 

 kinds of weather. 



The life of the Standard Maginnis Flume is the Channel Binder, because of the 

 protection given the galvanizing, not only by checking the silt but by checking the 

 sand (which is more or less common to all irrigation water), which if permitted to travel 

 through a flume with the same velocity as water would cut the galvanizing off and 

 leave a plain sheet of metal. You know the results. 



I am speaking from experience. To be exact, January 19, 1904, I received Patent 

 Number 749871 for smooth inside flume. I, like a good many others, thought I had 

 everything that was needed. At my own expense (not yours) I tried this flume out, 

 more to determine the actual carrying capacity for measurements, etc., than anything 

 else; to my sorrow I found that the sand would cut off the galvanizing when carried 

 by the water through a smooth inside flume. I did not impose on my customers by 

 putting this flume on the market, but continued to make the old reliable "MAGINNIS 

 FLUME" which has now stood the tests for eleven years and given entire satisfaction. 



A word about patents: I am the sole owner of the Maginnis Flumes patents, which 

 were issued in 1902-1904 and cover inner and outer clamping members, inner binders, 

 carriers rods, etc., in other words the only method of connecting two sheets of metal 

 together and making them water-tight, without using rivets or solder. First used by 

 P. Maginnis in experiments in 1901.
