In a vapour-burning lamp, the combination of the vaporizing-tube extending across the lamp-chimney above the vapour-burner, and a preheating tube for the oil also extending across the chimney at a higher point therein. (5.) In a vapour-burning lamp, the combination of the vaporizing-tube extending across the lamp-chimney above the vapour-burner, and a preheating tube for the oil also extending across the chimney at a higher point therein, together with a heat-shield placed over the vaporizing-tube for the purpose of concentrating the greater portion of the heat of the burners on said vaporizing-tube. (6.) In a vapour-burning apparatus, the combination of the vaporizing-tube with a thermostatically operated valve therein, and the filter in the line of the fuel-supply connection to the lamp, in which filter all impurities are collected, and prevented from passing onward to the valve. (7.) In a vapour-burning apparatus, the combination of the vaporizing-tube having a valve located at its inlet end, a thermostatically operated apparatus for opening and closing said valve located in the tube and so constructed that the valve-plunger will be held down to its seat during the initial period of the preheating of the vaporizing-tube, but lifted from its seat when the tube has been raised to the temperature for vaporizing the oil admitted thereto. (8.) A thermostatic-valve-operating rod for vaporizing-tubes composed of two metals of different coefficients of expansion, the metal having the higher coefficient of expansion being in contact with the walls of the tube. (9.) A thermostatic-valve-operating rod for vaporizing-tubes composed of two metals of different coefficients of expansion, the metal having the higher coefficient of expansion being in contact with the walls of the tube, the two metal parts being adjustably connected, and constructed substantially as shown in Figs. III. to VII. (10.) The combination of the vaporizing-tube extending across the lamp-chimney above the vapour-burner, and the thermostatic valve located in the inlet end of the vaporizing-tube outside of the zone of greatest heat, substantially as shown in Figs. I. and X., whereby the valve will not be opened by the

initial heating of the middle portion of the vaporizing-tube, but will be opened by the heat conducted to it after said tube has become heated to a high temperature. (11.) The combination of the vaporizing-tube having a valve-seat at its inlet end, a valve-plunger, a spring holding said plunger against the seat as the vaporizing-tube expands under heat, and a stop for said spring, substantially as shown in Fig. VIII., whereby the valve will be opened only after the tube has been heated sufficiently to expand it a predetermined distance. (12.) The combination of the vaporizing-tube of iron, a valve in its inlet end, a rod of metal having a high coefficient of expansion which extends lengthwise of the tube and reaches nearly to the valve-plunger, as shown in Fig. IX., whereby said rod will lift said valve from its seat when the unequal expansion of the tube and the rod caused by a predetermined degree of heat has brought the end of the rod in contact with the valve-plunger. (13.) A horizontal vaporizing-tube for vapour-burners having a casting screwed to one end, said casting having a discharge-opening in its under-side, and a passage-way extending therefrom to the upper portion of the interior of the tube, as shown in Figs. III., IV., V., and X. (14.) A vaporizing-tube for vapour-burners having a casting provided with discharge passage-ways screwed to one end, a casting having inlet passage-ways and a valve-seat screwed to the other end, and a valve-rod mounted in the first casting, extending lengthwise of the tube and co-operating with the valve-seat in the other end, substantially as shown in Fig. X. (15.) The combination of the vapour-burner, the vaporizing-tube in the heating-zone of the burner, the heating-chamber also in the heating-zone of the burner, and the condensing-chamber located in the line of connections between the heating-chamber and the vaporizing-tube, said condensing-chamber being cylindrical in form, with its axis vertical, and having its inlet from the heating-chamber discharging in a tangential horizontal direction, while its outlet to the vaporizing-tube connects with its upper central portion.
