Opis

The Inventors in the Colorado Territory and their U.S. Patents, 1861-1876: An Annotated Index contains the names of inventors from the Colorado Territory who were issued patents between 1861 and 1876. A copy of their patent filing is included, along with an index of the names of the patent holders, the witnesses to the patent filing, and the lawyers who filed the application. Understandably, many of the inventions pertained to advances in mining techniques, but not all. There were changes to medical equipment, a machine to make cutting gloves easier, military gear, agricultural machinery-even a new horse shoe.
