Charles N. Pogue: High Mileage Carburetor In Jan. 3, 1935 Charles N. Pogue was issued a Canadian patent – 353538 – for a High Mileage Carburetor. In Apr. 9, 1935 Charles N. Pogue was issued a US patent – 1997497 – for a High Mileage Carburetor. In Jan. 7, 1936 Charles N. Pogue was issued a US Patent – 2026798 – for his newer High Mileage Carburetor.
Pogue used the carburetor for about ten years on his car and produced about 200 carburetors thru the Economy Carburetor Co. In early 1936 Breen Motor Company, Winnipeg, Manitoba, Canada tested the Pogue carburetor on a Ford V-8 Coupe and got 26.2 miles on one pint of gasoline. The performance of the car was 100% in every way. Under 10 mph the operation was much smoother than a standard carburetor. T.G. Green, President of the Breen Motor Company did the tests. In April 30,1936 Ford Motor Company, Winnipeg, Manitoba, Canada tested the Pogue carburetor and is at "a loss to understand" how the carburetor got "25.7 miles on one pint of gasoline"! (That's approximately 205 mpg). Mr. W.J. Holmes and Mr. Purdy conducted the test for Ford Motor Company. In Aug. 10,1936 S. Stockhammer tested the Pogue carburetor on a 1934 Ford V-8 Coupe and got 28 miles per pint of gas. "I can say the performance was all anyone could desire in every shape of form." In Dec. 12, 1936 Canadian Automotive Magazine states that the standard carburetor gets about 25 mpg at only 9% efficiency. Therefore the Pogue carburetor is 72% efficient overall at 200 mpg. In 1953 CARS magazine stated that in the opening months of 1936, Pogue panicked the Toronto stock exchange and threw fright into the major oil companies. Stock exchange offices and brokers were swamped with orders to dump all oil stock immediately. This same article states that Winnipeg's largest automobile dealers tested the Pogue carburetor and got results of up to 216.8 mpg! In 1945, according to an unnamed source, carburetors marked "POGUE CARBURETOR, DO NOT OPEN" were used on American Army tanks throughout WWII but were removed from circulation after the war ended. In 1980 Arthur C. Sgrignoli, after 45 years, has built a legendary Pogue carburetor by hand and is said to have achieved an efficiency of 86%. Contact was made through his brother, William J. Sgrignoli. In 1981 Ultra-Lean Carburetors of Northridge, CA, was selling a set of plans for the Pogue carburetor for $50. (This price is too high). (I remember gasoline was a little cheaper then. Gary Vesperman) As of January 1981, Charles N. Pogue was still alive at age 81 and was living in a rest home in Winnipeg, Canada. He refuses to talk to anyone or to receive visitors from outside his own family.
