(Cl. 102—35) 2 1 comes airborne by the parachute a “snatch” occurs between the parachute and the candle. This “snatch” is utilised to open the screen. When the device is packed in the case the ribs are folded down alongside the ?are candle in the direction of the arrows, the said plate 5 thus being drawn down on the case extension until it rests on the top of the said candle case. As soon as the aforesaid “snatch” occurs the plate thereof a number of ribs each of which has hinged thereto a rib which extends beyond the 10 will be caused to slide upwardly on the extension and draw the ribs hinged thereto to a position top of the candle and is secured to a plate inclined to the axis of the candle, and these adapted to be lifted by a parachute and slidable ribs in turn will move the main ribs which are on an extension secured to the candle case, the hinged to the top of the case also to a position two sets of said ribs being covered with opaque material, so that when the ?are is released the 15 inclined to the said case, so that the covering thereon will form an eifective screen to prevent “snatch” caused by the parachute opening moves upward glare from the candle. It is preferred the said ribs to a position inclined to the ?are that the upper ribs should be hinged to the plate case and the covering thereon provides an eifec at points which are offset with respect to the tive screen. The invention will hereinafter be described, by 20 points on the candle case where the main ribs are hinged so as to avoid having to pull the said' way of example, with reference to the accom ribs over a dead centre. panying drawings in which Fig. 1 is a view in If desired, a coil spring, rubber pad or the like elevation of a device in accordance with this can be arranged in the slot to prevent the pin invention, the device being shown in its air borne position and Fig. 2 is a diagrammatic illus 25 slidable therein from jarring too heavily against the end of the slot when it is pulled into its up tration of the device in its airborne 'position permost position. showing the relations of various parts more clearly. We claim: 1. A parachute-supported ?are candle com Referring to the drawings, the candle case I has secured to the top thereof an extension 2 30 prising a casing having an extension thereon, a plate movably mounted on said extension, means having a slot 3 therein arranged axially thereof. arranged to be operated by the opening of a para A pin 4 is provided in the said slot on which is supported a plate 5, preferably of greater diam chute to raise said plate on said extension, a set eter than that of the ?are case. The pin is so of ribs hinged at one end to the upper end of said arranged that it can slide up and down in the 35 casing, a second set of ribs having each rib said slot and at the same time allow the said hinged at one end to the edge of said plate and plate to slide up and down therewith. at the other end to a rib of said ?rst set inter Hinged to the top of the ?are case are a number mediate the ends thereof and opaque material on of ribs 6 covered with opaque material ‘I to form each set of ribs to provide a screen for said ?are a screen and hinged intermediate the ends of candle when said ribs are raised upon the raising each of the said ribs is a rib 8, all the ribs 8 also of said plate. being covered with opaque material. The ribs 2. A parachute-supported ?are as claimed in 8 extend beyond the top of the ?are case and claim 1 wherein the opaque material on said are hinged to the periphery of the plate 5. The ?rst set of ribs does not extend to the pivot covering on the ribs 6 does not extend completely 45 points of the ribs and the opaque material on up to the top of the ribs. The material on the the second set of ribs extends above the upper ribs 8 overlaps‘ all the material on the ribs 6 edge of the material on said ?rst set of ribs and above the line where the ribs 8 are hinged to has a fullness of the material between the ribs the ribs 6. A certain amount of fullness is allowed of said second set whereby louvres are formed in the material between the ribs 8 so that air 50 for the discharge of smoke from the candle when will pass between the two covers and will lift the the ribs are raised. outer cover to form a louvre.

This invention relates to illuminating ?ares, more particularly of the kind dropped from air craft and supported in the air by means of a parachute, and has for its principal object to provide improved means for screening the said ?are so as to prevent upward glare therefrom. The present invention consists in a parachute supported ?are candle having hinged to the top In operation the ?are with its parachute is ejected from a case.
