FLOYD SMITH, OF SAN DIEGO, caLIronNmfassIGNon To' FLOYD sMI'rIr'AEaIAL EQUIPMENT COMPANY, a CORPORATION or ILLINOIS.

PmcIIUTE umass'.

`To all whom z't may concern:

Be it known that I, FLOYD SMrrrny a citizen of the United States, and residentof San Diego, San Diego County, California, and temporarily residing at Chicago, county of Cook, `State of Illinois, have invented a. certain new and useful Improvement in Parachute Harness, and declare the followand exact description of the same, such as will enable others skilled in the art to which it pertains to make and 'use the same, -reference'being had to the-accompanying drawings, which form a rt of this specification.

y invention has forits object to produce a simplel and novel harness for attaching a parachute pack to a wearer in such a manner that one can readily get into and out of the harness, can quickly and convenientl adjust it to fit his person, will have a maxlmum vfreedom of movement while wearing the harness, and be comfortable and at the same time securely held in making a descent.

The standard parachute ack of today in this country is one whic is opened by means of a release cord having at one end a ring which, is grasped b the wearer and pulled. It is of course hig ly essential that this ring be always maintained in a osition to which the wearer willinstinctive y reach when he desires to open the pack. A further obj ect vof 'the present invention is to produce a simple, novel and eiiicient means for hold- 2 ing the ring of a pull cod in'a definite,

' ment, but insuch a. manner that the wearer of the pack may easily pull the ring out of such position when the pack is to beo cned.v

' Y .after be v 'the claims; but, for a full understanding4 of fixed position agalnst accidental displace- The variousfeatures of noveltywl ereby my invention is characterized will hereinpolnted out with particularity in my invention and of its Objects and advantages, reference may be had to the following detailed description taken 1in connection withthe accompanyin drawings, wherein:

l cord, land the clip for vholding the ring in pending members connected together so as to form a single lon vU-shaped loop. This loop is made of suc -a length that it will form a swing'in which the wearer of the harness in effect sits. Near the middle portion .of the cross piece, 3, of the swing are fastened two straps, 4 and 5, which are carried forwardly between vthelegs of the wearer and are Athen detachably-connected to the lower ends of the upright ieces, 6 and 7 lof thtl swing, namely to the ower ends of theyarms of the U.l The connections between the free ends of the straps .4: and 5

andthe elements

6 and 7 are adJustable` so as to permit the crosspiece or seatielement 3 and the two straps to form two adjustable leg-encircling' bands. In the arrangement shown, eachof the members 4 and fhas at its free end a snap hook, 8, which is adapted to be hooked into anyone of a (p urality of links in a short chain, 9, attache at one end tfjthe correspending vertical member of the swing. In placing the pack on his back the wearer inserts -his arms vunderneath the suspending straps where they leave the pack, so that the vertical portions of the swingextend downwardlyl across his.l chest. To the pack, on the side next to the wearer, is secured' a 'waist strap, 10. Two other straps, 11 and 12, crossingl each other near the top ofthe'- pack are secured to the side of the latter which comes `next to the wearer, the upper end of the'strap 11 goin forwardly overthe left shoulder underneat the corresponding suspending stra and being fastened at its free end tothe vertical element,6, ofthe swing; while the lower end of the strapll passes forwardly underneath the arm of, the'wearer and lis adjustably connected by means of 'a buckle, 13, or otherwise to one end of the waist strap, 110; the. strap 1 1 being long enough s O that on a rson itV maybe made to lie in a loop exten ingabouthalfway across the front of the wearer.v This loop portion-of the 11 isthreaded through an eye in "a sna P hook, 14, orpthelike which is adapted tO-be` strap are shortened because those engaged with a ring, 15, secured to the eleover the right shoulder of the wearer and is fastened vto the element 7, while the lower end is carried forwardly underneath the left varm and, after being looped through an eye in a snap hook, 16, is fastened to the other end. of the waist strap, 10, by means of a buckle, 17, or other adjusting' device; the hook 16 being adapted to be engaged with a ring, 18, secured to the element 7 of the swing directly opposite the ring 15.

It will be seen that the harness in unfastened, the parachutist gets into the same by simply slipping his arms, one after` the other, under the main suspending straps while the pack isat his back, thus automatically bringing the seat strap intothe proper position; this being a much simpler opera- .tion than that of putting on a loose coat and being more analogous to the simple operation of getting into a pair of trouser-sup lporting Suspenders" that have already been are hooked into the rings 15 and 18.- If thev harness happens to be too large, the adjustment is ma e at the buckles 13 and 1 7, namely between the free lower ends of the

straps

11 and 12 ,and the front ends of the waist strap 10. As the harness is made smaller,

the effective upright portions of the swing ortions of the

straps

11 and 12 that comel orwardly over the shoulders and are fastened to the

swing elements

6 and 7 become the effective upper ends-of the swing elements until thepack is opened, p ermittingslack to be .formed in the l shoulders.'

thereof wit Vsuspen suspending members at and' behind the The pack is adapted to vbe opened by means of a pull on a release cord, indicatld at 20 in Fig. 4, and provided at the end a ring, 21, adapted to be sped by the wearer ofthe pack.' The reease c ord is carried forwardly shoulder, preferably underneath one of the ding straps. f 'In the arrangement shown, the release cord carried forwardly 24; the parts being so roportioned that the.-

portion will project in positionto be easily Iprotected by the overlying part, 7, of the and conveniently grasped when the release cord is to be pulled. v
