Description

DLPETERS, PHOfQ-UTNDGMPNER. WASHINGTON1 D C.
No. 17,251.R. SNoWl-JEN nnnnws, of Baltimore, Bld- Improved Apparatus for Heating and Cooking by Gas..-Patent dated' May 12, 1557.--The apparatus rests on the'gas-burner E; the gas escapes through E into the cylinder b, and the atmospheric air enters through the apertures c of the bottom p; the mixed lgas and air passes out through the apertures b, and, upon being ignited, the flame is made to play upwards and around the sides of the boiler, which'rests en disk A current of air passes through the pipes h, which becomes heated as it passes thrcughsaid pipes, and, escaping through the holes p of disk f, tends to impart great intensity to the `Jrire, upon the-principles of oxydation and hot draughts.
,f :The inventor says: I do not claim '.thewtiibesuhtand the hot-air chamber g, except as combined with my peculiar apparatus.' v
