Abstract

16,341. Delage, M., and Woog, P. July 13, 1908, [Convention date]. Void. [Published under Section 91 of the Act.] Lighting burners by electric devices.-Relates to means for electrically igniting burners for railwaycarriage lamps by means of induction sparks. The insulated electrode e, Fig. 1, may be arranged to pass through an insulating sleeve d to the inside of the burner grating f, which acts as the earthed electrode, as shown in Fig. 1. This arrangement is stated to be applicable also to pilot burners, because of its compactness. The insulated electrode may be arranged to pass through the gas nipple, and, in another arrangement, a pilot jet which passes through the centre of the burner may act as the insulated electrode. The electrodes e should terminate in a lateral extension, so that the ignition sparks may jump vertically. In the arrangement shown in Fig. 13, one or more holes are made in the insulating piece g, and a metal tube t in contact with the grating is arranged to facilitate lighting. The electrode e may be outside the mantle support, so that the ignition sparks pass through the mantle i, Fig. 16. As shown in Fig. 17, the electrodes are supported above a globe by arms x, and a bell for collecting gas surrounds the electrodes. Fig. 18 shows a railway lamp in which the electrodes are arranged to be readily moved aside. They are pivoted about a rod 8, and a spring 12 is provided to restore them to their operative position above the mantle, the insulated conductor 10 serving as an abutment for the electrode e. As modifications, it is stated that the insulated conductor may pass through the axis 8, the insulating sleeves 6, g of the electrode e may be in one piece, the conductor 5 may be a metal sleeve surrounding the insulating sleeve, and an insulated tube with two passages may be used. The arrangement may also be used above the globe, and is applicable to inverted burners. The rotary movement may be replaced by a sliding movement. When a portable magneto is used, a spring placed on the crank axle may be arranged to be wound up, so that lighting is effected by liberating the spring. The size of the spark may be increased by a condenser arranged in the sparking circuit, with the poles connected respectively to the insulating wire of the secondary and the other wire which is earthed.
