Application September 14, 1944, Serial No. 554,067 ' 2 Claims. (Cl. 244-445) 1 2 My invention relates to improvements in para chutes, the primary object in View being to equip A relatively small, auxiliary umbrella section 9, substantially circular with the exception present such devices for quick, easy and safe control, as regards both speed and direction in descending, ly noted, is provided on the under side of the um.. brella I and which is of sufficient size to close said and also for easy control of the same on the vent opening 3_ and overlap the edge of the same ground. so as to be compressed against said edge under pressure of air in the umbrella I and thereby seal Other and subordinate objects are also com said opening 3 around the edges thereof. prehended by my invention, all of which, together The auxiliary umbrella section 9 is also formed with the precise nature of my improvements, will be readily understood when the succeeding de 10 of gore sections I0 of `any suitable material hav ing side edges overlapped and suitably secured scription and claims are read with reference to together to provide radial seams II of double the drawings accompanying and forming part of thickness of the material, and said auxiliary um.. this specification. y In said drawings: brella section 9 is scalloped around the edge Figure 1 is a‘view in top plan 0f a parachute 15 thereof between said Vseams II, as at I2, to facili tate ballooning action of said section. The seams equipped according to my invention in the pre_ II correspond in number to the seams 3 so as to align with the latter for a purpose presently seen. Figure 2 is a View in transverse section taken Attaching lines I3 for the auxiliary umbrella on the line 2-2 of Figure 1, Figure 3 is a View in plan, partly broken away, 20 section 9 are provided which are suitably fixed in the seams I I to extend along the same and extend and looking at the under side of the parachute, out of the outer ends of said seams. The attach Figure 4 is a fragmentary View partly in side ing lines I3 are extended through openings I4 in elevation and partly in transverse section and the under sides of the seams 3 into said seams drawn to an enlarged scale, Figure 5 is a fragmentary view in plan partly 25 and from said openings along said seams 3 to sub stantially the outer edge 0f the umbrella I. From broken away, the openings I4, the outer end portions of the Figure 6 is a diagrammatic view illustrating attaching lines I3 are suitably secured in said the manner in which the auxiliary parachute sec seams 3. From the openings I4 to the auxiliary tion may be manipulated to accelerate the de scent and cause lateral movement in one direction, 30 umbrella section 9, said attaching lines I3 are exposed and somewhat slack, and the openings Figure 7 is a similar view showing how the I4 are spaced sufñciently remote from said sec auxiliary parachute section may be manipulated tion 9 to expose the attaching lines so that the to cause quick straight descent,À edge of the auxiliary umbrella section 9, as pres Figure 8 is another similar view showing how ferred embodiment thereof, the auxiliary parachute section may be manipu lated to cause accelerated descent and lateral movement in the opposite direction relative to `that in which said parachute will move as illus trated in Figure 6. Referring to the drawings by numerals, accord ing to my invention, a usual parachute umbrella 35 ently described, may be pulled away from the edge of the vent opening 5 or permitted to close said opening. Manipulative pull lines I5 are suitably attached at one end to the outer ends of the seams II to 40 depend therefrom for grasping by the person de scending in the parachute. , I embodying gored sections V2 having overlapped The manner in which the described. invention is to be used and operates will be readily under side edges secured together to provide seams 3 be stood. When the parachute is descending and tween said sections of double thickness of materi al, and harness suspension lines II interlaid be 45 the manipulative pull lines I5 are relieved of pull thereon, the auxiliary umbrella section 9 is tween the double thicknesses of the seams 3 to pressed against the netting 8 and the edge of the extend along the same, is provided with an axial vent opening 5, by the compression in the um comparatively small, circular vent opening 5 brella I and against said section, and said open bounded by a hem 6 to which said seams 3 extend, and in which is suitably secured a circular anchor 50 ing is closed. By pulling the edge of the auxiliary umbrella section 9 at one side thereof away from cord 'I to which the lines 4 are suitably attached. the edge of the vent opening 5, as illustrated in A circular section 8 of netting extends over the vent opening 5 and is suitably attached at its edge Figure 6, the parachute may be caused to quicken to the hem 6 on the outer or upper side of the its descent and to move laterally in one direction. 55 By manipulating the pull cords I5 to pull the edge umbrella I. 3 2,404,659 4 of the auxiliary umbrella section a'way from the edge of said vent opening 5 all around said edge, as Ishown in Figure 7, the parachute may be caused to quickly descend with a suddenly ac celerated action. By pulling the edge of the auxiliary umbrella section 9 opposite to that vshown in Figure 6, as similarly manipulated, away from the edge of the vent opening 5, the para chute may: becaused to,I descend with an acceler ated action- and to move» in the direction oppo site to that in which it willbe moved according to the showing in Figure 5. _ As will be seen, the vent opening 5 and the edge thereof, together with the auxiliary umbrellaì section 9, form, in operation, a valve in the-axis,> of the umbrella I and which may be opened vari-` lease vent, and radial seams extending from said opening to the perimeter of the umbrella, means operative to close said opening under pressure of air in said umbrella comprising an auxiliary um brella section larger than said opening to overlap the edge of the same, means to attach said Isec tion in said umbrella comprising cords attached to the edge of said section and extended into said seams intermediate theY endsv of thev same with 10 end*x por-tions» extending along. the seams and fixed therein, and pull lines attached to said section at Í different points whereby diiferent portionsl of said y section may be pulled away from the opening to variably open the same. '21. In a; parachute, an umbrella having a cir <cular axial opening therein forming an air re ' lease vent, and' radial seams extending from said celerate descent of the parachute and?or direct openingÍ to the perimeter of the umbrella, means the same laterally as required. By completely to close said opening under pressure of opening, or uncovering,` the vent opening 5 when 20 operative air insaid umbrella. comprising an auxiliaryf um the person descending has reached theV ground, collapse of the` umbrella l" may‘be‘faci'litated' and> brella section` larger than said. opening tov overlap. the edge of theA same,` mearisto` attach-said seohandling and' control of' theI para-chute in col tion in, said umbrella comprising. cordsr attacl'ied> lapsing the same rendered easyl and safe. , to theedge ofsaid section` andextended into saidThe foregoing will, it is believed, suñice- to inr 25 seams intermediate the ends ofV the samewith part a clearunderstanding' of my'invention with» outer end portionsextending along the~ seamsand out furtherA explanation'. ilxed`tl`1erein,V p_ullj lines attached to. said section ` Manifestly; the invention; as described, is sus at, diiïerent. points whereby different` portions of ceptible of' modification without' departing from said section` may be pulled" away from the open the inventive concept, and right' is herein` re ing toïvariably open the sama, the inner end por served to such modiñcations asfall within the tions> of the> cords beings attachedÍ to. the` edge of scope of the appended claims.
