Abstract
17,154. Graetz, A. July 20. Oil-lamp burners.- The wick-tubes a, b are shaped as shown. The contraction of the lower part of the inner wick-tube a not only facilitates the insertion of the wickcarrier d, but also permits of the use of a screw collar c of smaller diameter, by which means large burners can be fitted to lamp reservoirs having small screwthread openings.
