Patents from 1910 through 1919

Patents are an effective way to understand the development of street lighting in the United States. In this section I have posted patents as I located them. (Early patents are difficult to locate as they were not cross-indexed.)

All patents are listed in order of their filing dates. Click on the patent number or thumbnail to view the entire patent.
