Patents from 1900 through 1909

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.

By 1900 the push continued to develop higher intensity lighting for urban streets, although there still were improvements being made in the field of gas and oil lamps where electricity wasn't available or the cost of conversion from gas was excessive.
