as represented by the successors in office Secretary of War and his 'Application May 25, 1938, Serial No. 209,965
3 Claims.
(Cl. IGZ-24) (Granted under the act -of Maren 3, 1883, as
amended April 30,
` kThe invention described herein may be manufactured and used by or for the Government for ,governmental purposes, without the payment to me of any royalty thereon. v
The subject of this invention is a are. Ground flares for illuminating the landing field rof an airport are` employed in large numbers and are individually ignited.' In order to obtain effective illumination of the eld the flares should be 1g positioned some distance above 'the ground, for
` example fifteen feet.
The purpose of .this invention is to provide a flare in which the ignition mechanism is so arrangedthat it may be readily operated by a person on the ground. By virtue of this arrangement one person may ignite a large number of ares in a short spaceof time:
To these and other ends, the invention consists in the construction, arrangement and combination o f element-s described hereinafter and pointed out in the claims forming a part of this specification.
A practical embodiment of the invention is illustrated in the accompanying drawing,
wherein,
Fig. 1 is a. viewin side elevation of the improved are carried on a mast and prepared to be ignited;
Fig. 2 isa longitudinal sectional view of the are with the shipping cover in place;
Fig. `3 is a transverse sectional view through the cap and the ignition mechanism taken on the line 3-3'of Fig. 4;
Fig. 4 is a sectional view on the line dof te Fie- .3:
Fig. 5 is a sectional view on the line 5-5 of Fig. 4.
Referring to the drawing by characters of reference the flare comprises a tubular casing 5 whereby it is mounted on a mast A and a tubular casing 6 which is attached to the casing 5 and contains a charge l of an illuminating composition and the usual first charge 8.
A metal cap 9 mounted on the end of the casing 6 and attached thereto by means of shellac varnish is formed with a diametrically extending arched portion I0 which constitutes a housing for containing the igniting mechanism. A thimble Il containing an annular compressed primer charge l2 is held in the arched portion by crimpl ing the bases thereof as at l3--I3 and it is maintained in one end of the arched portion by crimping the` sides thereof as at I-HL A pull wire I5 having a coiled inner end I6 coated with a friction composition Z8 is threaded through the annular primer l2 then through an aperture I1 in the base of the thimble, and inally through an aperture i8 in the sloping end Wall i9 of the arched portion. A bend 20 is then formed in the Wire and is disposed in the space between 5 the thimble and the sloping end wall. This bend provides resistance to accidental movement of the wire during storage, handling and preparation of the are for use. The outer end of the wire is formed into a loop 2| to which a long cord 22 is 10 attached. The aperture I8 is sealed as at 23 with a suitable material such as painte The cap 9 is provided' with vent holes 24-24 which are normally closed by rupturable waterproof sheets 25 affixed tothe cap. 15
A shipping cover 26 fitting over the metal cap 9 andconning the coiled wire l5 and cord 22 is retained in a conventional mannei` by means of adhesive tapel 2l; This cover is removed when the flare is placed on-the mast in readiness for 20 use, and the cord 22 is positioned to be conveniently seized by an operator. Theigniting mecha anism'is functioned by merely pulling the cord.
I claim: l. In a flare, a casing, a cap on one end ofthe 25 casing, said cap .formed with a diametrically extending arched portion having a sloping end with an aperture, a thimble held in one end of the arched portion by crimping the bases and sides of the arched portion, a primer carried by the 30 thimble, a pull wire passing through the primer and the aperture in the sloping end of the arched portion, said wire having a bent portion disposed between the thimble and the sloping end of the arched portion.l 35 2. In a flare, a casing, a cap on one side of the casing, said cap formed with a diametrically extending arched portion having a sloping end with an aperture, a thimble held inone end of I the arched portion, a primer carried by `the '40 thimble, a pull wire passing through the primer and the aperture in the sloping end of the arched portion, said Wire having a bent portion disposed between the thimble Yand the sloping end of the arched portion. 45 3. In a nare. a casing, a cap on one end of the casing, said cap provided with a raised portion forming a housing, a primer carried Within the raised portion and a pull wire passing through 50 the primer and the cap and movable through the cap in igniting the primer, the inner portion of the said pull Wire being coated with a friction composition. v
