EMEBGEKCY-LANDING FLARE.

Application filed August 8, 1925. Serial No. 47,267.

My present invention pertains to a para chute flare intended to be dropped from aircraft for the purpose of illuminating the land or water and any other objects beneath a the flare.

The invention is adapted for use in making night landings by operators of aircraft who wish to land on fields not illuminated and due to the short interval of 10 time from the instant the flare is launched until full illuminating is produced, it is especially adapted for emergency landings in unknown territory in case of storms or trouble. 7

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

Referring more particularly to the drawings 12 designates a case for housing the parachute 13; and 14 indicates a somewhat" is closed by the cover 27 of wood or other to Figure 8 and showing a:

similar case for holding the illuminating composition 15. These cases may be made of paper or other appropriate material. The adjacent ends of the cases are brought together on a joining block or plug 16 of wood or appropriate material, the case ends belng secured as by nails or other fastenings 17 and 18 to the plug. annular rib 19 projecting centrally about theplug serves to space the ends of the two cases apart and also to hold the screws or lugs 20, which project beyond the sides of the device for a purpose later explained. The illuminating composition is confined between the discs 21 and 22 and the disc 22 is spaced from the bottom 23 of the case to provide a place for containing the igniter assembly indicated at 24. This assembly may be of any well known construction. A tube 25 passes through the illumination composition 15 from the'plug'lfi to the igniter assembly. This tube housesthe igniter wire 26 by means of which the igniter is operated. V

The upper end of the parachute case 12 appropriate material adapted to be received into the upper end of the case and to be secured thereto as by the nails or appropriate fastenings 28. The cover 27 is provided with an annular flange 29 which extends beyond the outer side of the case for the purpose of supporting the device in the launching tube as hereinafter referred to. The cover 27 may be provided with a handle 30 for carrying the device about prior to its insertion in the launching device and the cover is furthermore provided on its inner side with the screw eye 31 or other appropriate device to which to attach the parachute. The shrouds 33 of the parachute 13 are connected to the flexible cable 34 which is disposed in the cavity 35 in the upper portion of the joining block 16. This cable 34 is fixed in the safety disc 36 which acts as a cover for the cavity 35 and is nailed or otherwise secured to the block 16 as indicated in Figure 2. The igniter wire 26 is attached to the. flexible cable 35, and the lower end' of this cableis attached to the joining block 16.

The device so formed is adapted to be )la'ced in thelaunching apparatus, as shown in Figures 8 to 11 inclusive. This launching device consists of a tube 37 mounted upgn no an airplane part at 38.

device is placed in any convenient location in'the body of the aircraft or fuselage'of the airplane in such a manner that the flare dropping required.

will extend throughan opening in the floor. The flare and the launching tube 37 will be disposed in a vertical position to permit the of the flare out of the tube when The flare is held in place in the tube by means of the engagement of'theflange 29 on the top cover 27 with an internal shoulder 39 on the ring This ring 40 is the upright 42. This upright is hollowed out adjoining the bar 41 to receive the 'pulley '43 carried upon the upright andthe lower I pulley 44 carried upon the bar 41. A cable pulleys having one end secured as indicated at 46 in Figures 8 and 9 to a stud in the upright, while the other end passes out laterally and is disposed in position to be pulled upon by the oper is. trained over these ator. Of course any appropriate mechanism 7 may be used to operate this-cable. When the cable is pulled the ring 40 will be hoisted.

The'lugs 20 of the flare are adapted to slip under internal lugs 47 within the launching tube 37. These lugs are spaced apart to permit the screws or lugs 20 of the flare to be inserted downwardl between the same and then turned to enable the lugs 20 to engage beneath the lugs 47 as shown'in Figure 9.

When it is desired to make a landing at night and the flare is -to be dropped to illuminate the unknown territory, the cable Y 45 is pulled, elevating the ring 40 and with illuminant case as the fastenings it the parachute container 12. The parachute container will readily strip from the 18 are only small pins or thin nails. During this operation the remainder of the flare structure is held against this upwardly pulling by the engagement of the lugs 20 and 47. When the parachute container 12 is pulled clear of the illuminant case, the flare fallsfrom the aircraft, the parachute container 12' remain ing in the releasing device. The illuminant 14 falls free from the launching-tube 37, pulling the parachute 13 with it. The slackof the shrouds is taken up until-the whole weight of the flare. is brought on'the attachment 32. The resulting jerk on this connec-. tion will strip oi the mit the cable 34 to'straighten out. The condition of the parts just referred to is indicated in Figure 11.

As the cable 34 straightens out it will pull upon the igniter wire 26 and operate the igniter thereby setting off the illuminatin material'l5. The further descent of the safety disc 36 and per-f flare will finally break the u per connection flare then becomes detached of the airplane. After approximately a'fifty foot drop, the the burning flare as it floats to the ground.

In Figures 4 to 7 inclusive is shown-a different quire a connection betweenthe parachute and parachute container. This is. the safety lever type and consists of a striker 48 mounted to swing about the pintle 49 and urged by the coil spring 50 to the position, shown in Figure 7 against the 'primer51. The-striker occupies normally a retracted position within a bottom bottom head of the illuminating case. In this posit-ion it. isj-held by' the safety lever parachute opens supporting cavity 1 52 in the;

type of 'igniter, which-does not r'e- 53 pivoted to the case bottom as at 54 and extending. across the cavity 52. -The lever along the side of the flare case. The upper .end ofthis arm 55 is normally disposed throughan opening in block 16 and held underneath the wall of the parachute case, F1 ure 4.

t is apparent that, so long as the arachute-case remains in place on the illuminant case, the arm andlever'w'ill retain the posit-ion shown in Figure 4, holding the striker n a potential position. As soon, however, as the-parachute illuminant case, Figure 7). The lever-and arm. will fall .down and permit the striker to become active when the illuminant case is free of the launching tube under the influence of the coil spring 50, thus igniting the illuminant.

It will be apparent from the foregoing that the. invention produces a self-contained flare which will be positive in action and constructed with a view to its ready launching. 7 Wit -h the foregoing and other objects in view, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise'embodiment' of the invention herein disclosed maybe made What is claimed is partments therein, illuminating. material in .116 within the scope of what is claimed without I departing from the. spirit of the invention.
