The end Figure 2 is a vertical longitudinal section of the mouth is turned in and forms a somewhat through the flare casing showing therein the reduced hole 11. Located on the inside of the 55 cartridge case in position for firing. mouth is a cup 12, which rests upon the turned-in electric conductor is attached for grounding pur-- poses. The bottom of the cup and the plate 16 have holes therein in which there is an insulating ring 19. Resting upon the plate 16 and the insulating ring 19 is an insulating disc 18, while below the bottom of the cup there is a second insulating disc 20. These discs and ring are held together by means of a copper bolt 21, which has its head resting upon the insulating disc 18.- Cooperating with the head for clamping the insulating discs and the insulating ring are two nuts 22. These nuts not only serve to hold the bolt in position on the mouth of the container, but they serve as a clamp for clamping the end of a wire conductor 23.

Within the inclosure formed by the cup 12 and the hard paper disc 14 is powder 24 adapted to be ignited for expelling purposes. Embedded in this powder is a cylinder 25, which also has powder 26 therein. In the powder 26 within the cylinder 25 is a fine wire 2'7, which is caused to glow by the passing of an electric current therethrough. To one end of this fine wire is attached one end of a conducting wire 29, which leads to the upturned end of the plate 16 for grounding purposes. The other end of this fine'wire is connected by means of a wire 28 to the head of the bolt 21.

The other end of the cartridge case or container is closed by means of a cap 30, which is adapted to rest in the enlarged part of the sleeve in the top of the supporting frame. Within each container or flare casing is a cartridge case 31, shown in section in Figure 3. Adjacent one end of this cartridge case is an inwardly directed head 32, which serves as a shoulder for limiting the inward movement of an annular cup member 33. The end of the cartridge case adjacent the bead is spun over, as at 34, to engage the periphery of the outer wall of the annular cup, as clearly shown in Figure 5. Within the annular cup there is a cup 35, which has around its periphery at the closed end thereof, a flange 36 engaged and supported by means of the turned-over or spun end 37 of the inside wall of the annular cup. This cup has a seat thereon similar to the cup 12, which supports a disc 36 heid in position on the seat or shoulder by a turned-over edge 39. Extending into the bottom of the cup is a fuse tube 40, closed at one end 41, with laterally extending holes 42 therein adjacent the closed end. The end of the cartridge case Justdescribed rests upon a thick, heavy circular metal disc 43, which has a hole in the center thereof to receive the fuse tube 40. On this fuse tube is a shoulder 44, which prevents the disc from leaving the adjacent part of the cartridge case.

Adjacent the disc 43 and around the fuse tube is a relatively thick felt disc 45, held in position by means of a second thinner metal disc 46, also having a hole through which the fuse tube passes. The lower end of the fuse tube is open, and has lateral holes therein. Located above the annular cup is a second felt disc 47, which has in the center thereof a hole 46 directly above, the cardboard disc38.

Fitting within the cartridge case is a cylindriable material. This carton is cylindrical in shape, and has its lower end closed by means of a metallic cap 50, with a hole 51 in the center in line with the hole 48. This carton rests on top of the felt disc 47, and has in its bottom a layer of powder 52.

Above the layer of powder 52 and filling the carton, is flare material 53. The upper end of this carton is closed by means of a disc 54. The cup 35 andthe fuse tube have therein powder 55. Attached to the disc 54 is one end of a wire 55a. To the other end of this wire is attachedone end of each of a plurality of strings 56,.which have their other ends attached to a parachute 57.

This parachute and the strings are properly folded and placed within the cartridge case above the carton containing the flare material. The wire is coiled above the disc 54 and passes between the side of the cartridge case and a felt packing 58 located immediately above the carton containing the flare material.

Immediately above and below the packing 58 is a thin disc 59 of some suitable material. The upper disc supports within the'cartridge a tube 60, which forms a casing for the folded parachute. In the upper end of the cartridge case and resting on the upper end of the tube 60 is a packing 61. This tube 60 with the packing 61 and one of the discs 59 form a casing or housing in which the folded parachute is contained before it is discharged, and when in position to be discharged.

Within the tube 60 and between the packing 61 and ihe upper disc 59 is a plurality of flat spacers or thrust members 62, about which the parachute is coiled for support within the tube. These strips of suitable material prevent the parachute from becoming compressed and hold the parts in proper position so that when the fiare is discharged the parachute will properly open without interference.

The numeral 63 indicates a battery for supplying an electric current for discharging the charge of powder within the mouth of each container. From one end of this battery a ground wire 64 extends. From the other end a lead 65 extends to a binding post 67 of a switch case 66. From this post 67 wires lead to a plurality of contacts, one for each of a plurality of switches. Each switch is opened or closed by means of a lever 68, 68a or 68?). By operating the lever 68 contact is so made that a current will flow from the battery, through a wire 70 attached at one end to a binding post '71. This wire is connected at its other end to one of the wires 23, attached to the copper bolt ofone of the flare casings.

For locking the lever 68 in position so that it cannot be operated for making contact and closing the circuit, there is provided a lock member 69. When the switch lever is in off position, as shown in Figure '1 and the lock is in the vertical position, the switch cannot be moved for making contact, and cannot be moved until the lock is moved from the vertical position, or from one. end of a slot 69a to the other end.

, The switch lever 68a is operated to make contact so that the current will flow from the battery, through a wire 70a attached at one end to a binding. post 71a. The other end of this wire unites with one of the wires 23.

The switch lever 68b is operated to form an electrical connection between the battery 63 and the wire 70b connected at one end to a binding postflb. The other 'end of this wire 70b is connected to one of the wires 23.

position, as shown in Figure 1, the switch levers cannot be moved. When they are moved to the right-hand end of the slot 690 the switch levers may be moved for contacting purposes so that each of the flares may be discharged. The current passing through the wires 70, 70a and 70b causes the small wire to glow and discharge the powder around it.

It will be further understood that the tube 60 may be split at 72 so that it will readily fall apart and free the parachute when the appropriate time comes for the parachute to open.

It will be further understood that I desire to comprehend within my invention such modifications as come within the scope of my claims and my invention.
