U.S. patents issued to Thomas A. Edison from 1883-88
This is a Patent Office compilation of U.S. patent drawings issued to Thomas A. Edison between 1883 and 1888, published in Washington, D.C. in 1900 as a reference record. The pictures are line-engraved patent figures showing electrical devices, lamp bulbs, and machine assemblies with lettered parts and reference numerals, useful to a designer looking for schematic, technical diagram styling with fine hatching and labelled callouts.
