If Mr. Giles did design the so called "Fry Mae West" pump, he did not patent it (even a design patent) here in the U.S. Early patents by Mackensie easily show that he designed this pump. He either sold or licensed the patent to the Guarantee Liquid Measure Pump Company. GLM advertised this pump as early as 1917, no mention of Giles. Somewhere between 1917 and 1924 when the Giles name started appearing in the Fry ads something happened, this is the grey area I am trying to figure out.
Mackensie was an inventor, he held many patents including many that had nothing to do with gas pumps. Also Rochester was the home of the Correct Measure Pump Company, Mackensie also designed and held the patents for their so called pipe organ gas pump. He also designed pumps for the Springfield (Ill.) pump company.
Can't make any assumptions, just have to analyze the info I have.
