The connection between Giles and Fry has never been fully research or explained.
About a year ago I received a phone call from a person living in Michigan. He said either he or his wife were related to Phillips Giles and that Giles had invented what we call the Fry Visible. He even said he had proof, but he wasn't willing to give me a copy so I could put the pictures in my book.
This is what I do know. Giles does not hold any U.S. Patents, the Fry Visible was patented by MacKenzie, in the U.S. This is my feelings, MacKenzie licensed the pump to Guarantee in the U.S. and to the Phillips Pump Co. in Canada.
As mentioned before, Giles purchased the Phillips Pump Co., somewhere in the early 1920s.
Here is some more information. Go to this page of my website:
http://petrolianacollectibles.com/guarantee%20pumps.htmScroll down to 1924 or 1925. Click on anyone of the ads for a larger picture. This is the year when the Fry ads added, Phillip Giles Pump Co., Kitchner, Ontario. One more thing, click on ad #Gua-43 and read the ad, somewhat interesting. This is also the year they started to put the base on the pump.
Now scroll down to 1927, again click on anyone of the pump ads and you see it now reads, Fry Equipment Co. of Canada. Sounds like Guarantee purchased the Giles Company.
I have written four different articles for "CTO" about these pumps, each one after I have found more information, but have never been able to put all the information together to get a true picture of the dealings between Phillips/Gile/and Guarantee.
It sure would be nice if that guy in Michigan would release what he has, but for some reason he wants to know he has something that no one else has. It will probably wind up in the trash someday.
