This invention relates to illuminating flares and has for its object to provide a flare device which will provide illumination for a prolonged period, for example for a period suflicient to enable an aircraft to land while the flare device is being used to provide an emergency flare-path.

According to this invention a flare device, especially for .use for providing an emergency flare path, comprises a base, a plurality of substantially vertical tubular metal casings mounted on said base, a flare candle in each casing, means for igniting the top of the flare candle in the firstcasing, and means for igniting the top of'the flare candle in each other casing when the flare candle in the next preceding casing has almost burned through.

'The meansfor igniting the first candle may .consist of a suitable length of fuze projecting from the top of the candle. The top of each other candle may. be connected by means of a length of fuze to a point towards the lower end of the next preceding flare candle.

A convenient embodiment of the invention will now be described with reference to the accompanying drawings in which,

Figure 1 is a side elevation, partly in section,

of a flare device according to this invention,

Figure 2 is a plan view of the device of Figure 1, with one of the loose caps removed,

Figure 3 is an underside plan view of the device of Figure 1,

Figure 4 is a section of the lower end of the device taken on the line IVIV, Figure 1, and

Figures 5 and 6 are an end elevationand side elevation, respectively, of a cover for the base of the device;

Referring first to Figures 1 to 4, four tubular metal casings I to 4 are mounted on a base 5 consisting of two horizontal flanges 8, 'I between which is a raised portion 8 through which the lower ends of the casings I to 4 project. The lower end of the casing I is provided with a slot 9 facing the casing 2, and the casings 2 to 4 have slots II] to I2, alternatively facing flanges 5 and I. The raised portion 8 of the base 5 is provided with three orifices I3 to I5 adjacent the casings 2 to 4. A metal channel [6, formed by bending a flat piece of metal into substantially V-shape, is secured to each of the casings 2 to 4, for example by welding, in such a position that it extends from near the raised portion 8 to a point near the top of the casings 2 to 4, providing covered passages above the orifices I3 to I5. The casings 2 to 4 are provided with orifices I! to l9 adjacent the upper end of the channels IS.

The casings I to 4 may be closed by loose caps 20 for protection of the contents from the atmosphere. Each of the casings contains a flare candle 2! from the top of which projects a short length of fuze 22 for the purpose of igniting the candle. The candles are supported on wooden plugs 23 in the lower end of the casings, each plug 23 being provided with a cutaway portion 24 for the passage of a fuze. A fuze 25, which is embedded in the candle 2! in the easing I for a suitable distance from the lower end thereof is led through the cutaway portion 24, through the slot 9, along beneath the base 5 between the lower end of the casing 2 and the flange I, through the orifice I3, up through the channel I 6, through the orifice II into the top of the casing 2 where it is tied to the fuze 22 projecting from the top of the flare candle 2I in the casing 2. A fuze 26 leads in a similar manner from the bottom of the flare candle in casing 2 to the top of the flare candle in casing 3, and a fuze 2! leads from the bottom of the latter flare candle to the top of the flare candle in casing 4. The disposition of these fuzes 252I beneath the base 5 may be clearly seen from Figure 3. A fuze 28, leading from the bottom of the flare candle in casing 4 may either be cut ofi, as shown in Figure 3, or it may be tied to the fuze projecting from the flare candle in the first casing of another flare device similar to that shown in the drawing. In this way eight flare candles may be coupled together, instead of four. It will be understood that although the device shown in the, drawings consists of four tubular casings l to 4, it is possible to use two, three or any other desired number of casings, depending on the time during which it is necessary for the flare device to provide illumination.

After the flare candles 2|, the plugs 23 and the various fuzes have been arranged in position, the space beneath the base 5 may be filled with an inert composition, such as clay; this has been omitted from the drawing for the sake of clearness.

When the flare device is to be used on grassa cover such as is shown in Figures 5 and 6. This cover comprises a sheet of metal 29 the edges of which are bent over at 30 and which is provided with spikes 3|. The edges 30 are adapted to slip over the flanges 6, i of the base 5, and the spikes 3| can be pressed into the grassland or earth so that the flare device is held firmly in the desired position.

When the flare device is to be used, the cover is removed from the casing l and the fuze 22 ignited. When the flare candle 2| in the casing I has nearly burned through, the fuze 25 is ignited and in turn ignites the flare candle 2i in the casing 2, and so on. In this way the flare candles burn one after the other providing illumination for a period four times as long as would be the case with a single flare candle.

We claim:
