Historical information
The Kosmos burner is probably the most popular burner used in European lamps. A patent for the design was first lodged in the UK in 1865 by Wild & Wessel from Berlin. In 1875 they began using the trade mark 'Kosmos' on winder knobs. The mark was taken over in 1899 by Brokelman, Jager & Co. who changed it to 'Kosmos Brenner', (literally 'Kosmos burner'), they continued to manufacture right up to the 1970's when the factory closed and most tooling was destroyed.
A very popular burner in Germany and still manufactured today in France it has been used in all sizes of lamps from small hand lamps up to large table and hanging lamps.
