Application January 10, 1948, Serial No. 1,620 a shrouds leading down from th parachute canopy.

As soon as a parachutist has completed his descent, to alight on land or water, the imperative thing to be done isinstantly to free himself from said suspending straps. Thereafter, and rela-, tively speaking, more at leisure, he may divest himself of the body harness.

There have been many proposals for quick breaking of the couplings of the harness parts,

and some of them have been excellent; but the present invention is not concerned with that aspect of development of the parachute art.

What the present invention provides is a simple appliance, to be worn across the breast of the parachutist, from the first donning of the body.

harness and during all of his descent with the' parachute; which appliance, rugged although of light weight, and comfortable on the body, will with absolutely dependable certainty maintain the body harness securely connected to said suspending straps, yet is adaptedby a single movement of a single manually operable actuator, such movement not accidentally capable of being performed, instantly to become effective to disconnect both suspending straps and so release the parachute from the body harness, thereby to free the parachutist from allparts of th parachute.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description .and accompanying drawing, and to the appended claimsin which the various novelfeatures ofthe invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure: 1

Fig. 1 is a front elevational view, showing part of the body of a person suspended from a descending parachute, and a now favored embodimentof. the invention in coupling condition relative Ito. said suspending straps from the parachute and Fig. 2 is an enlarged detail view in perspective, showing one of two members of two pairs of co,- operant members which are permanently secured to-the body harness. I a v Fig. 3 is a similar view, showing oneof the two complementary members of each of said pairs, which are permanently securedtosaid suspend: in: straps. I I v I...

Claims. (01.244451) Fig, 4 is a further. enlarged view, although a fragmentary one, showing partially in front elevation and partially-in section certain of the parts seen in Fig. 1.

.Fig. v5 is a front elevational view, showing a modification of. the appliance of Fig. 4.

Referring to the drawing more in detail, the parachutistlll is indicated as in a conventional type of body harness incorporatingshoulder straps I2, said straps downwardly converged at the front as breast straps l4 forconnection, as by a fitment or device. IE, to the upper ends of stomach straps I 6 divergingly downwardly extending for connection to other straps (not shown), these last connected to the waist strap .l'i, which waist strap at its back is connected to the rear downward continuations of the shoulder straps l2. I a

The device l5 may represent any known, or any desirable, form of quick-detachable coupling, operable in various ways. known in the art to break down enough harness-part connections to permitthe parachutist speedily to divest himself of all parts of the harness. As already stated, the present invention is not concerned with a coupling of the kind just mentioned, but, instead,

provides aquick-detachable coupling between the harness and the suspending straps l8' which de-,- pend from the lower ends of the shrouds leading' down from the parachute canopy. I Tothe lower end of each strap 18 isattached, as shown best in Fig. 3, the upper buckle portion [9 of a coupling member 20 including a bladelike transverse bottom portion 2l having an aperture 20'.

Such blade 2! fits in a transverse slot 22 across a complementary coupling member 23, the upper main portion of which is a casing 24 carrying elements to be described in a moment. Below the casing 24, the member 23 has a lower buckle portion 25, to which is attached the upper end of a breast strap 14, and also the front lower end of a shoulder strap"; these two straps l2 and I4 being shown in the present instance as stitched together as at 25',

Both the members 20 are identical, as'are also, except fora reversal of the location of the slot 22 and the buckle portion 25, both members 23, as will benotedfrom Fig. 1.

While the member 23 at the right in Fig. 1 is shown exteriorlyin Fig. 2,'reference is now to be made w-n1 where such a member 23 is illustrated asghaving inside the same an end- 1 Normally,

wisely movable cylindrical bolt 26. by endthrust from a strong expansile spring 21 Said spring 2 :is-backed by asthreaded sleeve plug 3!], which: after being screwedfiin all. the

To the lower end of the T-stafi of said unit'is secured ,the upper. endoi a metal flexible tube 33 .ofthe familiar spirally wound type: The lower. end offsaidltube is'closedby-a plate 34; suitably apertured for the passingtherethrougl'f'of apair of flexible elements, such. as. fine piano' wires; 35 and 36?.

It is to be understood that the parachute appliance may be positioned on the wearers back, chest, or at other positions in any suitable manneri When the deviceis .placed onsa person's back; the flexible; tube 3.3;ish'ould be; extended to the front of the wearer so that the handle 31 2.7136 at a convenient location.
