Dayton, Ohio has the unique reputation as being the city with the most patents per capita than any other city in the United States. It had over 1200 patents issued before 1868. I have been researching some of them because I find some of the inventions interesting. Dayton is famous for the airplane, the automotive starter motor, the ice cube tray and the pop top can BUT did you know that Dayton has claim to the automatic gate, a wringer and of all things House paint? Anyone who owns a Victorian brick house may find this patent interesting. It is for house paint and is from 1837. We still have flakes of this or something similar on our place.
