Christmas Tree Candles and Candle Holders - Web’s Largest Gallery of Historic Patents Shows How We Used To Decorate Our Trees; Huffington Post, 11/25/16

Tom Conrad, Huffington Post; Christmas Tree Candles and Candle Holders - Web’s Largest Gallery of Historic Patents Shows How We Used To Decorate Our Trees:
'Decorating with Christmas tree candles was in its commercial prime for about 50 years — from roughly 1870, gradually tapering off through the 1920s and 30s, although the U.S. Patent Office was still awarding patents for Christmas tree candle holders as late as 1945.
Studying patent drawings and reading the filings from the U.S. Patent Office is a good way to trace the design developments and get a feel for how the Christmas tree candle holders evolved through the years before they were overtaken by electric Christmas tree lights. The following selection is excerpted from our online Gallery of Christmas Tree Candle Holder Patents, which is the largest collection available on the web. Check out the gallery and see varieties of Christmas tree candle holders, clips and pendulums that are available to buy online."
