Vintage patent drawings

"Edison's Ark was begun in response to actions taken by the US Patent and Trademark Office (USPTO) to destroy the only two paper collections of US Patents that exist in classified order in the world.

Included in the trashing are the more than 1 million patents from the Golden Age of inventing - circa 1850 to 1910, when the first inventions in power, light, communications, transportation and chemistry appeared. The images on this site were literally rescued from the trash, and will be added to as time permits."

Edison's Ark and some examples of the vintage patent drawings.
