The patents almost always list the inventor or designer by name, and assign to the bigger company.
This is the text from the V39
"PATENT OFFICE DESIGN FOR A BEVERAGE VENDING MACHINE George H. Hansen, Jr., Kansas City, Kans., assignor, by mesne assigmnents, to The Vendo Company, Kansas City, Mo., a corporation of Missouri"
That makes sense. That's what I get for not reading all the documents.
