PARACHU'I'E PACK.

Application led October 25, 1936. Serial No. 143,938.

This invention relates to parachute packs such as are carried by the aviator.

The improvements ot the present invention are directed toward the provision of a parachute pack in which all dancer of the entanglement of various parts of the parachute is avoided. and wherein the construction enables the 'packing ot the parachute so as to give the pack a snug, trim form.

`With the foregoing objects in veiw the invention provides a liat front piece of the container and a back piece having iiexible side extensions which are connected to the front piece so as to hold a parachute therebetween. rlhe front piece is attached to the aviators harness and the invention is shown as relatinfrr to a seat pack on which the aviator sits when he is in the airplane. The `front piece of the parachute container is free of obstructions at its edges and the sides ot the parachute pack are formed as extensions of the back piece so that the entire container may he removed when the aviator pulls upon the rip cord, thus leaving nothing to hinder the release of the parachute from the front piece ot' the pack.

Further provisions ot the pack are lacing flaps provided on the side extensions so that the sides of the pack may1 be drawn up and the pack compressed after the parachute has been folded in place within the pack. The front piece of the pack is adapted to be worn against the aviator and atI its front are locking cones near its corners to which the side extensions of the back piece are detachably lastened, A lite preserving cushion is detachably fastened to the front of the pack so that it` may be easily removed. and this cushion is ot a lcneral horseshoe shape so that it ma7 be placed about the aviator's neck in case he should tall in the 'atei'. and thus keep his tace above the water. This cushion is adapted to function as a seat between thepack and tl c aviator. and to give a neat and trim appearance and torni to the front ot t-he pack where the overlappinf,r of the flaps and the pull cord and locking cones are provided.

HWith the above and other objects ofthe invention in view as will be made to appear in the acconipanyinp Ispecil'ication and claims, reference is had to the accompanying drawings in which Fig. 1 is a view of the front piece of the pack showing its outer side.

Figa 2 is ay central section thru the front piece as shown in Fig. l.

Fig. 9 shows the manner in which the pack is worn on the back of the aviator and shows the back piece removed and the shroud lines retained in thc Jfront piece of the pack, and

Fig. 10 is a plan view of the cushion.

Referring' more particularly to the drawings by reference numerals. the parachute container is shown as consistingA ot the front piece 1 of substantially rectangular forni, and4 the flexible fabric back piece 2, the side ei;- tensions 3 of which are adapted to forni the sides of the pack. The front piece 1 is of non-flexible construction and is reterably formed of a frame4 covered with abrio and provided with stifteuing' members at suitable points to maintain the rectangular shape et the pack. The parachute harness designated generally 4 has a lower end loop 5 which is Jfastened by the short strips of canvas tl to the i'ront piece 1 at its outer side.

The troutv piece 1 is so connected to the harness l that the pack may serve as a. seat for the aviator. The legar strips 'l' of the harness and the lower loop 5 thus fasten the fronti piece fast to the harness in its proper position. Shroud line retainers 8 and t) are provided on the inner side ot the front piece in the torm ot a fabric strip 'fastened to the front piece at the points 10 so as to relcasably hold the looped ends ot the shroud lines in place as shown in Fig. 9. rlthe parachute is placed in folded arrangement over the front piece l and the back piece 2 is then placed over the parachute and so folded alone; the lines l1 and 12 that thc side extensions il torni the sides et the pack. rl`hese side extensions are provided with

end portions

13 and 14 which are folded `over the edges ot the front piece and in front of the same. and grommets 15 provided in the ends of these end portions are placed over lockin cones 16 which project forwardly from t e front piece 1 at its corners.

A bellows corner is provided by means of 5 the projections 17 which extend laterally from the front and rear sides ofthe back portion by attaching the sides 18 to the sides 19 on theadjacent side portions 3.

The lift webs 20 which are connected to the parachute shroud lines, enter the pack at the back and a cut out portion 21 as provided at the back end portion 1i as shown in Fig. 3. It will be apparent that the entire flexible back portion of the parachute container is formed of a single sheet of fabric which is cut as shown in Fig. 3 and as previously described so that it may be folded into a rectangular box-like form and thus produce a neat and trim pack. The side extensions 3 are each provided with lacing flaps 22 arranged in pairs 25 vides a means for easily placing the parachute and fastened to the outer sides thereof so that the side edges of the pack may be compressed by drawing up on t-he lacing means 28 which lace the flaps 22 together. rlhis proin position and of thereafter tightening or compressingr the entire pack so as to give a neat and tr1m appearance without obstructtion whic way the surfaces of the back porare in contact with the parachute. The outer side of the back ortion of the ack, as shown in Fig. 4, is provided with webing 24 at the corners and strips of webbing 25`extending along the back so as to protect ing in anyl 35, the fabric of the back ortionfromwear ter the flexible wire casing 28 and the two wire casings 28 meet at the point 29 where casing at the point 29 since the casing 30 is not they are fastened to the pull cord housing 80. The two wire branches extend thru the casing 30 and are attached to the pull rin 31 which is releasably held in place on the arness in a suitable ocket in' the customary manner. At the

l ings

28 and 30 join, vis attachedA a webbing strip 32 which is sewed fast to the inside of the back portion 2 at 83 and slidably held by the short attachments 34 to this back portion. It will thus be apparent that when the pull cord T51 is jerked yby the aviator, when he wishes to release the parachute, the

pull cord branches

26 and 27 will be released from the locking cones and these branches will then j am in the sufficiently large to permit the branch extensions to pass thru all at the same time. Since the casing 30 is not held fast to the harness, the pull exerted on the ring 31 aft-er releasing the locking, cones, will forcibly pull back 2 int 29 where the wire casand webbing 32 which will thus bc manually and forcibly pulled off. of the pack. Since the front port1on 1 of the container is free of obstructions at its edges, the parachute will be forcibly pulled awa from the front portion when the back of th will then be immediately released and fallout of t-he back portion of the pack. The use of the unsatisfactory and unreliable rubbers to cause the opening of the pack is, therefore, unnecessary and the opening of the pack and release of the parachute is fully assured.

In order to protect the locking concs and lthe portions of the pull cord wires which en gage them, extension rotector flaps 35 are provided on the extensions 1i of the back of the container. These protector flaps each fold over a locking cone, as shown in Fig. 7, and are provided with a snap fastener 36 which engages with the fastening means 37 so as to releasalbly hold them in place.

The front portion 1 of the parachute coutainer is provided with four snap fasteners 38 projecting forwardly therefrom to which a life preserving cushion 39 is adapted to be detachably fastened by means of snap fasteners 40 provided in the face of the cushion. This cushion is referably of wedge shape as shown, and is ofpsuch a size as to neatly cover the entiretop of the pack. It is placed in position between the pack and the aviator so as to serve as a cushion on which he may sit. It further functions as a protector for the top of the pack where the fla'ps of the back portion are overlapped. -Thc cushion is rovided with an opening 41 which is slig itly larger than the neck of a man and the cushion is substantially horseshoe shaped so that it may be laced about the aviators neck. It is filled with kapok or other suitable life preserving material, or with air, so that it may act as a life preserver in case the aviator falls in water. In the case of such a happening, the aviator would immediately and quickly release the cushion from the front portion to which it is attached and place 1t around his neck and thus be able to keep his face above the water.

Altho my invention has been shown as aplicableto a seat type pack and in its rcerred form the front portion is of a nonexible character and the entire back portion of the container is of a flexible nature, I am aware that various changes and modifications of my invention may be made without departing from the spirit or scope thereof as set forth in the following claims.
