Patents
Patents have been a useful tool for me in my
research not only for their factual value but also their insight into the minds
of men who came before me.
A new kind of "Automobile lamp" from John's brother Aaron H. Gould and Aaron's son Nathaniel O. Gould
And Nathaniel's own "Reserve liquid fuel controlling device"
How about you? Have you ever found a relative's patent?
