Wi. liilZ-Zt) (Granted under the act of March 23, 13%, as

amended April 30,

The invention described herein may be manufactured and used by or for the Government for governmentai purposes, without the payment to me of any royalty thereon.

This invention relates to a fiare.

Flores that are designed to be projected into the air and used for signalling purposes are usually suspended by a parachute. When the :dare is arranged so that the burning surface is on the under side of the body of illuminant, the distended parachute serves as a screen or masie With resnect to observation from above asby the occupants of aircraft, and from such a position it is practicaliy impossible to determine the color characteristic of the iiare.

ln order to remedy this condition the flare of this invention is arranged to be suspended horizontal position so that both ends may burn simuitaneously to produce increased candle power, smoke or color effect.

tlith the foregoing and other objects in view, the invention resides in the novel arrangement and combination of parts and 'the details of construction hereinafter described and clairned, it being understood that changes in the ;oreoise embodiment of the invention herein disclosed may be made within the scope of what is claimed without dep arting from the spirit of the invention.

A practicai embodiment of the invention is iilustrated in the accompanying drawings, where- Fig. 1 is a View in side elevation of the improved fiare as it appears fioating in the air.

Fig. 2 is a transverse sectional view of the illuminant body.

Figs. 3 and 4 are sectionai Views taken on the respective lines of Fig. 2.

Fig. 5 is a longitudinal sectional view of an iiluminant body showing a modication oi the i 4D igninon reiay.

Fig. 6 is an end view of Fig. 5.

Fig. 7 is a sectlonai view on the line l-l of Fig. 5, and

Fig. 8 is a longitudinal sectionai view of the fiare cartridge.

Referring' to Figs. 1 to 4 the fiare consists generail` of a body of illuminant A connected by means of a cord 5 to the shrouds S of a parachute B.

The body of illuminant A comprises a casing 'I conveniently formed of a roiled paper tube and preferabiy having a central partition 8 of fire-clay or other inert material to provide two compartments for receiving a combustible iiluminating or signalling composition 9-9. The cord 5 is attached midway of the body A, preterably passing through a diametral opening iii therein and haying a knotted end' i l.

A first-re charge 12 is loaded in each end of the casing l to facilitate ignition of the main charge 9. Each end of the casing is closed by a cloth drum-head iii confining a priming charge M. An initiating charge is provided on the outer side of one of the drum-heacls. A tube iii, extending longitudinally of the casing and eccentrica'lly with respect thereto to avoid interference with the cord ii, houses a quick-match i? for relaying ignition from one end of the casing to the other. A delay-charge iii is preferably interposed in this'relay and disposed in the end of the tube 1 adjacent the initiating charge i Referring to the modification shown in 5, B, and 7 a quick-match iii for relaying ignition from one end to the other end of a iiare is secured to the outside of the fiare casing tli by means of an adhesively secured tape The ends of the quick-match overlie the ends of the iiare and are secured by tape Referring to Fig. B a cartridge comprises a cartridge case 'iii and a projectile consisting of a container housing the body of iiliuninant A parachute '5. The projectiie is propelled from the case 52ml by a charge 2b and a quick-match E'i ignited by the fiame from the charge transmits ignition to a delay or time charge in the base 'Titi of the container 25.

During the flight of the projectile the time charge 2h sets oif a charge which expels'the fiare from the container and ignites the initiating charge it on one end of the fiare. Ignition is relayed to the other end of the fiare by the match iii. The delay aftorded by the charge i pro- Vides a time interval during which the parachute may be opened and relatively moved a safe distance from the burning composition 9 as shown in Fig. 1. When the body A is susp'ended by the parachute its opposite burning faces are on an axis perpendicular to the Suspension cord 5.

I claim:

1. In a fiare, a casing having a central partition, a combustible composition on each side of the partition, a tube extendinglongitudinally of the casing and eccentrically with respect thereto, an ignition relay in said tube and 'including a delay charge, said relay available to opposite faces of the combustible composition, and a parachute for suspending the casing.

2. In a fiare, a casing having'a central partition, a combustible composition on each side of the partiton, a tube extending longitudinally of 5 the casing and eccentrically vvith respect thereto.

an ignition relay in said tube and including a delay charge, said relay available to opposite faces of the combustible composition.

3. In a flare, a casing having a central partition, a combustible composition on each side of the partition, a tube extending longitudinally of the csing and eccentricall with ;'espect thereto, an ignition relay in said tube, said relay available 10 to opposite faces of the combustibie composition.

4. In a flare, a body of a combustible composition, means i'or igniting opposite i'aces of said body. and a parachute connected to the body centrally between said ODDOSite taces.

5. In a flare, a body of a combustible composition, means for igniting opposite faces of said body, a parahute and a connection between the parachute and said body whereby the body is suspended with its opposite burning faces on an axis Drpendicmar to the connection.
