Abstract

411,806. Vaporizers. JOHNSON'S BURNER PROPRIETARY, Ltd., Ascot Chambers, Queen Street, Brisbane, Australia. Sept. 6, 1932, No. 24799. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 22, 1933]. [Class 7 (iii).] Fuels such as kerosene are gasified and delivered in that condition, under control, to an air intake pipe. Fuel from a tank 1, Fig. 1, is forced by a pump 2 to a release valve 4 and thence to a pipe 3 and coil 5, Fig. 6, within a chamber 6, Fig. 6, to which exhaust gases are admitted, the fuel pipe 3 passing through the exhaust outlet. Coil 5 delivers into a tube 9 by a valve-controlled passage whence the gas passes up tube 12 and is controlled by a valve 13 connected by a rod 17 and arm 18 to a flap 15 in the air inlet passage. The valve 13 is retained seated normally by a spring 19, and the flap 15 by a spring 20, the tension of the latter being adjustable by screw 23, spring 24 and pivoted member 25. The valve controlling the passage into tube 9 is spring loaded, appears to be actuated by rotating a cam-faced sleeve and is described with reference to Fig. 4 (not shown). A spring-loaded flap valve 21, Fig. 6, and the usual throttle valve 16 are provided. Starting may be effected by a lighter fuel by providing a petrol tank the flow from which to a valve 49, Fig. 6, is controlled by a valve connected to an arm on the valve for controlling the flow of the gasified fuel to the tube 9. The valve 49 is actuated by the flap 15 through the arm 18 and the petrol passes to the induction passage by way of pipe 51. Acetylene may be supplied to the induction pipe by connecting the cylinder of gas to the pipe 3 preferably near the air inlet 14.
