Fries, St. Louis, MO as Patent No. 187,839 on Feb. 27,1877, ex-Tony Moon collection (This patented oil lamp was of such a robust design that the inventor claimed it could be “dropped with impunity with no concern with breakage and without any oil leakage.” The patent specification noted that the lamp was of the type used by brewers and others. It is thought that it made its way into the mines due to its robust construction and pointed/hooked hanger arm.) SEE THE FRIES PATENT IN THE FOLLOWING PIC | Original Image |
