376,315. Liquid fuel burners. MASTERS, A. H., 1401, Keenan Building, Liberty Avenue, Pittsburg, U.S.A. Dec. 30, 1930, No. 30486. [Class 75 (i).] Liquid fuel is supplied to a heater stove through a vaporizing chamber, the inflow to and the egress from the chamber being controlled by valves to produce a, pressure between 50 and 650 lbs. per square inch. In the construction shown in Figs. 4 and 5 the fuel is drawn from a tank 142 by a pump 145 and delivered to a tank 147, which is connected, by a pipe 150 containing a fuel inlet valve 152, to a heater 151. The heater is formed by a thin walled casing 154 covered by heat insulating lining 160 and contains an electrically heated chamber 156. The fuel is forced through a porous diaphragm 161 and is converted into a vapour by the chamber 156, the heating being determined by a regulator which is responsive to temperature or pressure or both. A valve 164 in the outlet from the chamber is connected to the inlet valve 152 by a link 165 and the valves 164, 152 maintain the pressure in the chamber. In Fig. 5 the valve controlling the egress of fuel is formed by a plate 166 provided with ports 167 controlled by a disc 168 with ports 169 and the disc 168 'when rotated on its shaft 170 through gearing 178, 179 controls the valve 152a admitting fuel to the chamber 151. If the pressure in the heating chamber becomes excessive a diaphragm 182 is depressed against a spring 185 and a valve 181 in the fuel supply pipe 150 is closed. The outlet conduit 158 may be provided with a heating coil 186. At starting, in order to build up a pressure in the chamber 151 a valve 188 in a byepass 187 is opened to supply fuel to the chamber.
