Samuel Blatchford, Clough v. Gilbert Barker Manufacturing Company…
“ My invention is designed to obviate all difficulty in this respect, as the burner is set or made to let out at the tip the minimum quantity of gas that will produce a good flame, and, as the gasoline remains longer in the generator and becomes weaker in its illuminating qualities, the outer tube or shell may be turned so as to let out more gas and increase the flame without liability to smoke. ”
