Street Light Technical Information Willis Lamm   STREET LIGHT PATENTS From 1800 to the Present

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 have located them. (Early patents are difficult to locate as they were not cross-indexed.) All patents are listed in order of their filing dates. The index includes over 300 patents so the pages are divided into date ranges. Once on the correct page, click on the patent number or thumbnail to view the entire patent as filed with the US Patent and Trademark Office.

1800 through 1886 1887 through 1889 1890 through 1891 1892 through 1893 1894 through 1899 1900 through 1909 1910 through 1919 1920 through 1924 1925 through 1927 1928 through 1929 1930 through 1931 1932 through 1933 1934 through 1935 1936 through 1937 1938 through 1939 1940 through 1944 1945 through 1949 1950 through 1953 1954 through 1957 1958 through 1959 1960 through 1962 1963 1964 1965 1966 1967 Through 1969 1970 Through 1974 1975 Through 1979 1980 Through 1984 (More patents are continually being uploaded)
