On this episode of the GARY STOVER HOUR: we'll examine these huge volumes, looking for patents that cover items in our collections. We'll discuss a guide for dating through patent numbers. About a month ago I did a show on the transition from gas & oil lamps to electric lamps--thru these patents you can follow the changes & see what furthered the development & what didn't. I see this as more than a generalized social & economic history--it's a way of placing the antiques we own in their specific contexts.
