This v invention relates to the usual ttypes-sscf parachute assemblies whichlincludeaa pack that :zcomprises .a container, :8; parachutecanopy which is suitably attached :to the harness',:,and:ra 'piiot ,chute which assists withdrawing :the -;canopyf from the container when the container. is opened.
It is an object of the invention: to i provide a device inwhic'h the -pilot: chute willibezpositiveiy withdrawn from the con-tamer by :the opera'tor when the ripcord is operated to release the non- 'tainer closure, and which is so'- withdrawn:thatit 'wi11 be presented to the airs'tream skirt first and will withdraw-the canopy attire-parachute assembly from the container;peak 'iirst and thuspresent it to the airstream skirt first. I
It is a further object of theinvention to so construct the device that it maybe incorporated i-n parachute'packsof var ious types. e
With these and other -objects -'-in' view, such 'as will appear as the description-oi the invention progresses, the invention resides in thecons'truc- '"tionand arrangement of {partsillustrated in the '-drawing, described in th 4 specification and *recited in the claims.
In the drawings,- whereinthe invention is 'shown as applied to aback pack:

Figure 6is a diagrammatic view showing the Referring, now,-to *theconstruction'shown in *the drawings, the'pack includes aback 'l and " flaps 2, 3, 4 and *5. "In Figure 1" the lift webs '8- and I are illus'trated'as extending from the pack and from the shroud lines in the usual manner,
and a portion'of one of "the risers is illustrated Referring, now, to- Figure "-2 of the drawing's' the -"canopy 9 is illustrated aspacked within the 'conthe x'tainertin the-usual manner, that is to say, folded back and forth, and the shroud lines, which are attached ltO :theskirtof the canopy-at l0, lie in the usua'limanner against the back l of thereonwizainer. -The-peak H of the canopy 9, with its went, .=is packed adjacent the closure flaps 2, 3,
and 5, as illustrated in Figures 2.and 5.
"The-flaps are. illustratedas .heldin their closed 'rpositionsvby the-usual cones and grommets, the lfl zcone *Dnfithe :fiap beingfindicated by the refereence i2, thevcone .0n1;the"fiap 4 being indicated by the reference numeral !3, and the theme oni'the flap'B-beingindicated by the'referaencenumeral .14.: :e

which is illustrated'in'Figure:2aof the drawings. These flaps are held inttheir vclosedzpositions ioy -the engagementzof the grommets with theirespecitiveucones; and areiocked in thispositionxbya ir ipc'ord rwhic'h later will he described, and aonezof fizh-e flaps is provid-ed with -.a flap 2 0 which covers "the cones andg rommets and the adjacent portion ortheripcordthis flap1=20 being held inplace 'm the usual manner by' detachable snap fasteners 39 21;.
In=the= drawings the pilot *chuteis indicated :by -the reference character 22 and -'-it includes the usual lines 2'3 and 24 "for' attaching'it to the peak or the-canopy 9 at itsvent. 1 1 Inorder that -the pilot chutemay he with- -drawn -from the packwhen the flaps are released,
a fabr ic str ip' 25 is provided which is of sufficient s ize; both*transversely and"longitudinally, to permit it to be rolled with the pilot chute 22 in the manner-illustratedin thedra'w'i-ngs so that the pilot chute will'be completely enclosed within the --'stri-p.
iltavili'be;observedirom the drawings that the "peak-'26 of the pi'lot -chute -is' located :adj acentthe *c'entralportion-of the rol l'whii'e the iines 23 are :adjacent the outletof the roll, and that the line "24 "extends around *the roll and over the top *thei'eof 'to-the' peakof the canopy to which it is attached. The pilotchute-eiector flap Z5 is ar- 'rangedto extendoutwardly' betweenthe flaps '2, "3,--4-and-5, and'is' provided with a-"gremmetfl which-is engageable with thecone l z below the grommet on the flap 3. This flap 25-extends*beworld "the eone outwardly of" the pack and is at- 55 tache'd; as'a't 18/130 a ripcor'd housing'Z-B.
and is adapted to slide, but its relative movement is limited by an abutment 31 which is rigid with the ripcord and is adapted to engage within the sleeve 36 so that any further pulling on the ripcord at by means of the handle will result in the movement of the ripcord and the ripcord housing as a unit.
The ripcord housing 29 is provided with a clip 38 which is rigidly attached thereto adjacent its end and the sleeve 36 is adapted to engage with a loop 39 on the riser 8 adjacent the pocket 40 in which the ripcord handle is engaged.
When the parachute assembly is completely packed the parts will be in the position illustrated in Figure 2, wherein the canopy 3, with its suspension lines and the inwardly extending portions of the lift webs 6 and 1, will be within the container, and the pilot chute 22 with the pilot chute ejector flap 25 will be rolled together and within the container on the top of the packed canopy and adjacent the peak ii of the latter.
The flaps 2, 3, 4 and 5 will be held in their closed positions in the usual manner by the cones, grommets and ripcord pins. Moreover, the pilot chute and its ejector flap 25 will be held fixedly in the pack by the engagement of the grommet 21 with the cone l2, with the result that the ripcord housing wil be releasably attached to the cone by this means.
When the ripcord is pulled, it will be drawn through the ripcord housing longitudinally to disengage the pins 31, 32 and 33, from the cones with which they cooperate. When the ripcord handle has been pulled to an extentsufficient to cause the engagement of the abutment 31 on the ripcord with the sleeve 36, the pins 3|, 32 and 33 will have been completely, disengaged from the cones with which they cooperate. Further pulling force applied to the ripcord handle will, because of the engagement of the abutment 31 with the sleeve 36, cause the ripcord 30 and the ripcord housing 29 to move as a unit. In this movement, the grommet 21 will be disengaged from the cone [2, with the result that if the flaps 3, 4 and 5 have not already opened, the grommets on these flaps will be disengaged from the cones and the flaps opened. Moreover, the pull exerted on the flap 2 of the container, through the grommet 21 and the cone I2, will open this flap and continued pulling on the ripcord handle will withdraw the pilot chute ejector flap 25 from the pack and this withdrawal will carry the pilot chute with it. However, because of the attachment of the line 24 to the peak of the canopy 9, the ejector flap 25 and the pilot chute will start to unroll as they are withdrawn and this unrollingwill continue until the flap 25 and the pilot chute have been completely withdrawn from the pack, at which time the pilot chute 22 will be completely released from the ejector flap 25, as illustrated in Figure 6 of the drawings. It will be observed, of course, that in thi withdrawal and release of the pilot chute the 4 skirt of the chute will be presented to the air stream so that the pilot chute will be quickly opened. It will thereafter aid in the withdrawal of the canopy 9, peak first, so that when the canopy reaches a completely withdrawn position its skirt will be presented to the air stream and thus quickly will inflate.
' It is to. be understood, that details and specific arang'ements of the device that I have selected to illustrate my invention may be made -without departing from the spirit of the invention or exceeding the scope of the claims, and I, therefore, do not wish to be limited to those details and arrangements except in so far as is made necessary by the claims.
