Abstract: 1,059,997. Wick burners. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. May 20, 1964 [May 25, 1963; Dec. 12, 1963], No. 20836/64. Headings F4F and F4T. A wick burner having a cylindrical main wick 3 supported by an air conduit 2 is provided with an auxiliary wick 23 for lighting the main wick and with an extinguishing cover 41 which extinguishes .the main wick when the burner is upset. The auxiliary wick 23 is disposed in a holding member 20 fitted on the inside of the air conduit 2 and makes contact with the main wick 3 for the supply of fuel through an opening in the air conduit. The auxiliary wick protrudes from a supporting pipe 24 having an abutment 25 which projects through a slot 21 in the holding member. A spring 26 holds the supporting pipe so that the tip of the wick is retracted into an extinguishing pipe 22 mounted in the holding member 20. To ignite the burner an ignition lever 29 is pivoted about a pivot pin 28 to move upwardly an ignition rod 31 having a shoulder 33 which engages the abutment 25 and moves the auxiliary wick 23 upwardly so that its end projects out of the extinguishing pipe 22. At the same time a contactor 35 on the rod 31 is brought into contact with an ignition heater 27 to supply current thereto. The rod 31 also raises a perforated spreader 8 at the upper end of the air conduit 2. The auxiliary wick 23 is ignited by the heater 27 and the flame passes through a gap between the air conduit 2 and the spreader 8 to ignite the main wick 3. On release of the lever 29 the spreader 8 moves downwardly, the heater 27 is de-energized and the auxiliary wick 23 is retracted into the pipe 22 and its flame extinguished. The extinguishing cover 41 is fixed to the upper end of an extinguishing rod 38 pivoted at its lower end 40 to an extinguishing lever 36 pivoted on the pivot pin 28 of the ignition lever 29 and urged in anticlockwise direction by a spring 37. The extinguishing lever 36 overlies the ignition lever 29 so that, when the latter is pivoted to ignite the burner, the extinguishing lever 36 also moves to raise the extinguishing cover 41 clear of the main wick 3, and the lower end 40 of the extinguishing lever 36 is held in raised position by engaging with a stepped portion 43 of a locking lever 42 swingably supported by a guide member 32 secured to the air conduit 2. A V-shaped unlocking lever 44 is pivoted at one end to the pivot pin 28 and its other end abuts the floor 46 on which the burner rests. If the burner is upset a spring 47 acting between the locking lever 42 and the unlocking lever 44 causes the bent portion 45 of the unlocking lever 44 to thrust the locking lever 42 out of engagement with the extinguishing rod 38 which therefore moves downwardly under the action of the spring 37 to cause the cover 41 to cover the main wick 3. The air conduit 2 is formed integrally with a fuel reservoir and extends upwardly from the lower central portion thereof. A cylindrical perforated air regulating member surmounted by an annular air controlling tray is disposed outside a cylinder fixed to the reservoir and urging the upper portion of the main wick 3 towards the air conduit 2. A chimney having air inlets at its lower portion is secured to the fuel reservoir by a bayonet joint. An apertured cylinder is mounted on top of the chimney and has a cover and a handle for carrying the burner. Figs. 3, 4 and Fig. 5 and Figs. 6, 7 (not shown) show three different mechanisms for operating the ignition rod and the extinguishing rod. In the apparatus of Fig. 5, the extinguishing rod is not raised by pivoting the ignition lever, but instead is raised by the weight of the burner when it is placed on the floor.
