BUFFALO, NEW YORK, A CORPORATION PABACHUTE mnmzss Application filed September 11, 1930, Serial No. 481,317, and in Great Britain September 24, 1929.

This invention relates to improvements in parachute harness or rlgging for supporting a body or wearer during a parachute descent.

The primary object of the invention is the provision of a parachute harness which will safely and efficiently suspend a wearer during a parachute descent without liability of dropping therefrom, and which includes a single connecting device under the facile control of the wearer for instantly releasing the wearer from the parachute harness upon the exertion of a single manual effort.

A further object of this invention is the provision of an improved parachute harness of the U-swing supporting type having improved arrangements of leg encircling and shoulder straps which may be releasably connected by means of a single fastener, in an expeditious relation, and in such manner as to enable the harness to be entirely released from the wearer, so that the wearer is free to escape from the harness instantly upon alighting from a drop, without the liability of being dragged over the ground prior to the time that'the parachute canopy is deflated. i

A further object of this invention is the provision of an improved connector for parachute harness.

A further object of this invention is the provision of an improved parachute harness having leg attaching means of a self adjustingnature.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the drawings, wherein similar reference characters designate corresponding parts throughout the several views, the letter A may generally desi nate the improved parachute harness, whic may be used with parachute packs or apparatus of any approved type. In the drawings, the seat type of pack B is shown attached with the sling of the harness, although the harness is capable of use with any type of parachute pack, such as the lap type, chest type, back pack, or the illustrated seat ty e.

The harness is prefera ly constructed of woven textile flexible linen or other webbing, of high tensile strength, preferably in excess of 2800 pounds. The harness may be of other material if desired, and should be sufficientpension lines are arranged in and upon the upon the wearer, and. it should be sufiiciently flat to lie compactly against the body in sufiiciently snug form-fitting engagement.

The improved harness possesses some characteristics of the harnesses now in use, that is, to the extent that it is of the U-sling supporting type, and the lift webs or the suspack similar to conventional parachute apparatus. Among such conventlonal parachute harnesses as are in use throughout the world are those set forth in U. S. Patents Nos. 1,440,151; 1,560,366; 1,367,723, and 1,403,984; the second above mentioned patent representing the type of harness in universal use throughout the world. That type, however, requlres not only the use of a front connector to release the harness from the upper body of the wearer, but necessitates the use of independent fasteners for the leg encircling and holding straps. In the present invention only one connector is used to serve the purpose of expeditious donning and deffing of the harness.

The harness A of the present invention preferably consists of the main U-shaped sling 15 consisting of the seat portion 16 and the riser webs or straps 17 and 18, the free ends of which are provided with D-rings 19 and 20 respectively, or other types of fasteners for securing the shroud lines of the parachute canopy therewith.

Shoulder webs or straps 21 and 22 are provided, adjustably connected intermediate the ends thereof respectively upon the upper portions of the riser straps or webs 17 and 18, by means of suitable adjusting buckles or

fasteners

23 and 24 respectively, as plainly shown in Figure 2 of the drawings. The upper or outermost suspension strap ends 30 and 31 of the shoulder straps 21 and 22 respectively are provided with D-rings 33 and 34, or other types of fasteners, which receive certain bunches of shroud lines of the parachutecanopy in attachment therewith, in respective complementary relation with the sides of the

buckles

23 and 24, with respect to the

suspension ends

30 and 31, are provided with preferably permanently secured

fiat connector parts

40 and 41, in the nature of forged metal or stampings, having

eyes

42 and 43 for receiving certain detents of the single connector device designated at C in the drawings. These

fastener parts

40 and 41 may take the form of ordinary eyelets, but in the present instance they are provided with elongated slots for threading therethrough of the free ends of the shoulder straps 21 and 22, and therefrom are tapered -in reduced relation and at their free reduced ends have the

eyes

42 and 43 therethru as above mentione The harness A furthermore is provided with a'second U-shaped sling, generally designated at 47 in the drawings, which includes the portion 48 overlying upon the inner side and permanently stitched at 48' with the seat portion 16 of the main sling 15. The

minor or inner sling 47 is provided with short riser straps or webs 50 and 51 extending free from the riser portions 17 and 18 respectively of the major sling 15, and adapted to encircle along the outer sides of the legs of the wearer, in a cooperating leg clamping relation with an improved leg attaching strap loop 52, to be subsequently mentioned; the free ends of the riser straps 50 and 51 being adapted to be releasably positioned along the front of the wearer at or above the waist, in relative convergence towards their free ends, where they are provided with eye types of fastener parts 54 and 55, of the same nature as the

fastener parts

40 and 41 above described, and respectively provided with eye openings 56 and 57 The leg attaching loop 52 preferably comprises a closed loop, which includes the web or leg straps 60 and 61 permanently connected at 62 and 63 respectively upon the seat portion of the

slings

15 and 47, between the seat portions 16 and 48 thereof, or in any other approved relation, the leg straps 60 and 61 cooperating with the riser straps or webs 50 and 51 respectively, and the leg straps or webs 60 and 61 being connected by means of a cross portion 63, which may be stiffened by means of a metal insert 64 stitched or pocketed therein as shown in Figures 1 and 2. This metal insert is preferably of aluminum or some other light weight metal which will hold the illustrated rather horizontal or rectilinear,

shape of the portion 63, enabling its facile swinging between the legs of the wearer and means of a back cross strap 161, at a location fasteners 19 and 20. The front or lower free ends of the straps 21 and 22, at the opposite,

stitched at 167 to the straps 17 and 18, al-

though adjustable buckles may be here located to enable the vertical adjustment of the horizontal cross strap 161. A lower back strap 162 is provided, which fits across the small of the back of the wearer; being permanently stitched at 169 upon the riser portions 17 and 18, above the seat portions of the sling; the strap 162 continuing about the sides of the harness in position to engage about the sides of the wearer at or above the hips; these side portions being designated at 170, and at their free ends being stitched at 171 to the straps 50 and 51 of the inner sling 47, intermediate the ends of the straps 50 and 51. While we prefer. to permanently connect the body embracing strap 162 at the points a 169 and 171, we may provide adjustable connections atthese locations if desired.

The single connector device G is preferably permanently attached at some place to the harness. The position is a matter of choice, since it may be permanently connected to the free ends of either of the webs or straps 20, 21, 50 or 51, or it may be connected in some manner to the leg strap loop 52, as shown in the drawings, such as by means of an attaching strap permanently secured as at 71 to the portion 63 of the loop 52 between the ends of said portion 63. The attaching strap or web 70 lies normal to the length of the portion- 63, and it is of course flexible, and has the connector C attached to a slotted shank portion 72 of the latter.

The construction and formation of the connector is somewhat a matter of choice, although essential characteristics of the same are first, a compact, shallow, and relatively light weight construction which may fit closely in comfortable relation at the front of the wearer where it is accessible; second, that it permits quick attachment of the free ends of the harness straps 21, 22, 50 and 51 therewith, and third, that it permits of an instant release of its complementary fastener parts upon the harness by a single manual effort, such as a push or pull, to permit of an instant and entire release of the wearer from the harness, without the necessity of disengaging other complementary fastener parts. To this end, the preferred form of connector C is shown in Figures 3 to 7 of the drawings. It consists of a hollow body 80, which is preferably of four-sided rectangular appearance, with well defined corners that will enable the facile attachment of the eyelet or fastener parts of the straps thereto. This body is provided with a chamber 81, wherein the spring urged detents are mounted, as will be subsequently described, and retained in place by means of a cover plate 82, which is detachably held to enclose the chamber 81 as by means of detachable screws or like elements 83, similar to that shown in Figure 9. The body 80 is provided with an annular groove surrounding the same, and across this anv nular groove 85 may be positioned filler pieces 86, as shown in Figure 9, and located where the screws 83 intersect, in order to provide well defined slots at the corners of the body 80 for releasable insertion of the

fastener parts

40, 41, 54 and 55, as can readily be understood. As is best shown in Figures 6 and 7 of the drawings, the body 80 is pro- Vided with passageways 87 leading from the chamber 81 into the slots or groove 85; the passageways 87 being polygonal in plan and receiving therein spring urged detents 88, which are preferably hollow, and have compressed springs 89 therein engaging the cover plate 82. The springs, of course, urge the detents-88 outwardly and across the slots or groove 85 into abutment with the under surface of the body which faces the slot or groove 85, as is shown in Figure 6. These detents 88 are polygonal in section, and slide in their respective passageways 87 against rotation. They are provided with sloping cam faces 91, which face toward the outer periphery of the connector C to enable the facile riding of the ends of the eyelets or fastener parts of the straps to engage thereover as said fastener parts are pressed into the slots 85, causing depression of the detents 88 until they align with the eye openings thru said fastener parts, and at which time the springs urge the detents into the eyes, locking the fastener parts and the harness straps in place upon the connector C, as shown in Figure 6.

Means is provided for simultaneously releasing all of the harness strap fastener parts from the connector, by simultaneous depression of the detents 88. This means is in the nature of a depressible button device, and includes a reciprocating hub or hollow stem 93 slidable through an axial opening 94 in the body 80. Within the chamber 81 it is provided with a spider 95, the arms of which are engaged upon the flanges 96 at the inner ends of the detents 88. The outer end of the hub or stem 93 is reduced, and externally screw threaded, and detachably receives thereon a disc-like press button 97, which may be held fixedly in place by peening over the reduced end of the stem. It is at once apparent, since the disc-like-button 97 lies spaced from the outer surface of the body 80, that upon depression of the button, all of the plunger-s or detents 88 will be retracted against the action of their springs, simultaneously, for releasing the connector straps in a mannerwhich is apparent from the foregoing.

In order to prevent accidental depression of the button-like releasing device of the connector, various expe'dients have been devised which mayor may not be provided as desired. A preferred safetying device is that shown in Figures3, 4 and 5. It consists in providing a spring operated plunger pin acting radially in the body 80, which extends into a suitable bayonet slot type of groove in the stem 93. Thus, as shown in Figures 4 and 5, a shallow slot 98 is circumferentially provided inwardly of the external periphery of the stem 93, thru an arc of substantially 90. At one end it is provided with a normal extension 99 arranged in a line parallel with the axis of the stem 93, which at its free end terminates in a socket tension 99. Upon desire of the operator to set the connector for release from the harness strap fastener parts it is only necessary to rotate the stem 93 thru an arc of 90. Thereafter, upon'depression of the stem 93 for release, the plunger 101 will ride along the extension 99, and when the plunger 101 reaches the socket 100 the spring 102 will urge it into the socket 100, automatically locking the press button device in the position shown in Figure 7,- for holding all of the detents depressed and inoperative. To release it is necessary for the operator to pull the plunger 101 outwardly, and the press button device may be reset.

A modified form of locking device is shown in Figures9 and 10. It consists of a locking lever or fork 110, having a pair of spring-like metal arms 111 and 112, spaced to permit of their application upon the stem or hub 93"; the same gripping the stem to prevent their easy removal. These arms 111 and 112 are of sufficient height to prevent depression of the button-like releasing device. An added locking feature asshown in Figure 10, is that of flattening the stem 93" at diametrically opposed points, as shown at 116 in Figure 10; slipping the locking device 110 upon the stem 93 by sliding the fingers 111 and 112 along the faces 116; an enlarged socket- 117 being provided at the base of the fingers. 111 and 112,

- of the same diameter as the external diameter 4 of the stem 93*. Upon reception within the socket 117 the member 110 is given a turn of 90, more or less, to obviously lock the member 110 upon the stem to prevent depression of the button device, until the member 110 is swung to a releasing position.

A modified form of locking device is shown in Figure 11, consisting of a U shaped locking member having arms 120 and 121 resiliently urged towards each other and at their free ends being rounded to permit their being sprung into position upon the hub of the releasing device of the connector. If desired the fingers 120 and 121 may be recessed at 122, in facing relation, to set the position of locking of the spring arms upon the hub.

A modified form of connector is shown in Figures 12 and 13, possessing many of the characteristics of the form of connector C. It includes a body 180, having a chamber 181 therein, but the detents 182 are secured to or made integral with the spider 183, which is supported by a leaf spring or springs 184. Bosses 185 project from the chamber 181 to carry a cover plate 186, which forms one wall of an annular groove 187, corresponding to other wall. The cover plate is secured to the body by detachable screws 188 or the like elements.

When a harness strap fastener part is inserted into the annular grooveso as to de press a detent 182, the spider is tilted about its opposite corner and enables the fastener part to ride over the detent which on return locks the fastener part to the connector.

On operating the button-like releasing device 97 of the connector, the detents are depressed from engagement with the fastener parts and a spring operated plunger pin 189 in body 180engages the hole 190 in the spider, which is then locked in a depressed position until the plunger pin 189 is withdrawn by means of the button-like head 191.

The locking device for preventing accidental depression of the button-like releasing device is similar to that shown in Figures 9 and 10.

A modified form of connector 0' is shown in Figure 8, possessing many of the characteristics of the form of connector C. It includes a body 125 having a chamber 126 therein and being provided with spring urged detents 128 of the same nature as the detents 88 above described.

The releasing device for effecting attachment of the fastener parts of the harness straps upon the connector C is operated thru I The stem 130 is provided with a narrow an nular flange 135 which is spaced from the slot forming surface of the flange 133, and is adapted to seat in a socket 136 provided axially in the body 125, so that its outer surface lies flush with the surface of the body 125 from which detents 128 project. This enables the fastener parts of the harness to he slipped into position so that their inner ends lie in the groove between the facing surfaces of the flanges 133 and 135, when the fastener parts are locked by the detents. Upon rotation of the stem 130 by means of the fingers of the operator, it is'quite obvious that the eyelet or strap fastener parts will be lifted ofl the locking ends of the detents 128 to enable release of the harness fastener with a central reduced post 146 extending through the axial passageway 147 through the hollow stem 130, and upon which the latter is rotatable and longitudinally slidable in a guided relation. The post 146 at the outer-"end thereof is provided with a stop flange 147*, which may be detachable if desired, and which limits the extent of rotation of the stem 130.

As to the application of the harness upon the wearer, it is merely necessary for the pack B to be placed at the seat of the wearer, so that the wearer when in sitting posture will sit upon the seat portions 16 and 48 of the strap slings 15 and 47. The shoulder straps 21 and 22 are brought over the shoulders of the wearer, converging downwardly to the front of the wearer. The free ends of the straps 50 and 51 are extended through the opening defined by the loop 52 which is brought upwardly between the legs of the wearer, and the free ends of the straps 50 and 51 are then positioned convergently at the front of the wearer adjacent the location of the fastener parts of the straps 21 and 22. The connector C then receives the

fastener parts

40, 41, 54 and 55 in the manner that has just been described. In this relation of parts it is obvious that the harness is applied to the upper portion of the body of the wearer in a secure manner by reason of the shoulder straps; the back straps extend across the shoulders and at the small of the back of the wearer, and the legs of the wearer are adjustably encircled between the straps 50-60 and 51.61. The stiffener 64 holds the loop member 52 in proper position. Adj ustment of the harness according to the size of the wearer is secured through the

adjustable buckles

23 and 24. Adjustment here enables the straps 50 and 51 to be rendered sufficiently taut at the lower front and outer sides of the legs of the wearer, so that the leg straps of the loop 52, that is, and 61, are inclined outwardly by the pull on the straps 50 and 51, and adjust themselves according to the movement of the wearer, to insure comfort, and preventing injury to the user.

As shown in Figure 1 of the drawings, the harness is provided with a flexible canvas or other type of back pad 160, which may be suitably secured to the riser portions 17 and 18 of the harness and to the upper and

lower back straps

161 and 162; the same extending from the pack B to above the back cross strap 161. This adds to the comfort in stting for long periods in the harness, and if desired the back pad 160 maybe provided with aluminum or other type of stiffener strip 162 longitudinally at the side edges thereof to hold the harness in position to facilitate donning and dotting. The stiffener strip 162 may be placed directly in the riser portions 17 and 18 of the harness if desired, or they may be entirely eliminated, as may also the back pad 160. Furthermore,

a seat and float pad may be used on the pack, if desired.

In the arrangement of the harness upon the wearer it is to be noted that the suspensionstraps extend from the

buckles

23 and 24 over the shoulders and downwardly along the back at the sides of the wearer and into the container of the pack B where they are connected with shroud lines and the canopy packed in the container in the manner particularly set forth in U. S. Patent No. 1,554,- 192, or in any other approved manner. It is to be noted that the suspension points designated by the

buckles

23 and 24 he at the upper front of the wearer.

The rip cord for releasing the pack container and permitting ejection of the parachute may be of a conventional nature, and

has not been shown. It may be of the nature set forth in the. last above mentioned U. S. patent, and the rip cord handle may be supported upon the strap 22 in accessible relation to the hands of the wearer.

If desired, the leg straps 60 and 61 may be formed otherwise than as shown in the drawings, and directly connected permanently to the connector, as by a number of slotted shanks similar to the shanks 72 shown in the drawings. The connector itself does not necessarily have to be connected to the harness, although to prevent loss of the same it is thought best to attach it to some part of the harness. It is within our inven tion to permanently attach the connector to one or more of the straps of the sling 47, or to straps 21 or 22.

It is a notable feature of the invention that the entire harness may be adjusted upon wearers of different size at the two

points

23 and 24, thus not only simplifying application upon the wearer but enabling an instant release by means of the connector above described. The strain is equally divided in front and back of the wearer, so that the harness places no eccentric forces upon the body of the wearer.

Various changes in the shape, size, and arrangement of parts may be made to the forms of invention herein shown and described,

without departing from the spirit of the in vention or the scope of the claims.
