H. E. HAWES PARACHUTE Filed March 23, 1928 INVENTOR.

Patented Oct. 1, 1930 NITED STA HERBERT ELIEU HAWES, OF MILWAUKEE, WISCONSIH PABACHUTE Application filed Kai-ch 28, 1928. Serial 170,284,185.

My invention relates to improvements in parachutes and in which the aviator is suspended from the supporting-surface by a system of detachable suspens'ory-connected guys and accessories combined with a swivel-" mg aviator-harness connected with sald guys.-

As the harness ordinarily is in fixed nonswiveling position relative to the supportingsurface, the aviator on landing may be presentedbackwards against some obstacle and be injured seriously. Also, on landing, the parachute may still be inflated and the aviator be injured by being dragged by the in- Hated parachute over rocks or wire fences,

5 etc. before it comes to rest.

The object of my invention is to provide,

a way and means by which the aviator may turn himself so as to face forward at any time before landing, irrespective of the arachute so that he may see obstacles and he p himseli to avoid such and consequent injury to himself or'parachute.

Another object, is to provide means to deflate the parachute as aviator lands, to avoid danger to himself, or to the parachute by .be-

ing torn in draggin before it can be deflated.

I attain these ob ects by the combination,

construction, and operation of the mechanism, shown in the diagrammatic drawings accompanying this specification, and in which like numerals denote like parts in all the views, and in which Figure 1, is a side elevation of my invention showing a horizontal bodymember having a swingable guy-receivin arm pivoted thereto and at one side thereo a releasable locking-device comprising a lever 11 pivotally mounted thereon and springpressed into locking position, by spring 11', the swivel-member for the-aviator-harness, and the release-connection for unlocking the arm to deflate the parachute when lan i Fig. 2, is a plan view of the body of same, and the arm-pint and seat thereon. 4 V Fig. 3, is plan view of the vertically-swingable guy-receiving arm and pivot-joint bearing thereon.

ig. 4, is aside or outline view of the fan or instrument used by aviator in turning himself on the swivel-joint to harness.

In carrying my invention into practice I make use of an elongated, lower body-member 1, of metal, and having at one side thereof, a transverse arm-pivot seat 3, and at the opposite side, an enclosed, central, vertical cavity 7, for the reception of the free end of arm 2, pivoted thereto by pivot-stud 3', and for the locking-mechanism 10--11 for holding said parts together after the suspensory guys 2' are mounted on said arm.

Said metal arm 2, is of upwardly-curved outline, and has a transverse pivot-hole 3" in one end thereof, which engages with said pivot 3 in bod 1, and at the oppositeend, a central, vertica sunken, locknotch 9, for the recetion of the lockin -mechanism' 10-11. a side walls of cavity 7 extend arallel with the arc of motion of arm 2, and t e fioor 10' of cavity 9 extends downwardly and outwardly' so that roller 10, when under the strain irom guys, tends to lock itself more firmly therein.

By reason of the sunken'notch offering no protuberances on the inner side of arm 2, the outer guys thereon will encounter no resistance or obstacle, in exit or discharge therefrom, when the arm is unlocked by the aviator to deflate the parachute.

Said locking-device comprises a ivoted lever 11, having a transverse pivotole 13 for mounting same in bod 1, and an upwardl'y and inward] extending arm 14 having an end hole 15 or the attac' unent thereto of a vertical actuating-wire 15, which extends downwardly and t rou h space 7, and is provided with a lower end-- oop 17, for attachment thereto of a flexible cord 17', leadto within reach of the aviator.

he lower free end of said cord may be attached to some convenient lace on the avia-. tor-harness so as tobe at and for unlockin arm 2, todeflate the parachute.

k-lever 11 has also formed in its upper portion, a circular, transverse seat 18, for the reception of the anti-friction locking-roller 10, which bears against floor 10' in arm 2, when in locked'position.

Lover 11, may be held in locked position by a spring 11', located in said cavity and held by a screw 11" threaded in one side-wall thereof, and the free end of said spring bears against the under side of lever 11 and forces same into cavity 9 of arm 2.

The outer ends of the side walls of-cavity 7 are joined together by arib 19 between same.

Roller 10 may be held in seat 18, by slight ly pening both side-edges of said seat to raise a burr thereon, but it must be loose enough to turn freely therein and create slight friction when arm 2 is unlocked.

The side walls of cavity 7 are provided with transverse aligned holes 13 for the reception of pivot-stud 12 on which is pivoted lever 11.

In placing the parachute suspensory-guys 2 on arm 2, I divide said guys into two separate groups or sets, and the first set to be mounted onsaid arm, I form with small lowerend loops so that they have to be forced thereon, these guys are to remain permanently and not be discharged therefrom when arm 2, is unlocked; Fig. 1, shows one each of such guy-ends.

The second set, I form with relatively large end-loops so that they will readily slip therefrom when the arm is unlocked from body 1. As additional help to permanently retain the first set of guys on said arm, a cord may be tied around same outside said first set, or a raised stop may be formed on the arm at this point.

' Thus when arm 2 is unlocked, the outside set of guys at once slip off same approximately simultaneously and without drag or en tanglement, spill the air and deflate the parachute, and avoid dragging same across the field, or tearing the parachute. In order that the aviator may face about freely in any direction before landing, and to avoid having hlSbfiClC injured by being swung against a tree, wall, or wire fence etc, I provide a vertical swivel-joint in the body member 1, and to which I attach the strap 24 of the harness, thus making same freely revoluble. Said strap 24, is provided with a double or dual ring or loop at its lower end for the attachment of the harness-members in the usual manner.

At the middle of the lower or body-member 1, I form a vertical, transverse, hole 4, see Fig. 2.

In said hole I mount a swivel-bolt 5, and the lower end of said bolt I form, preferably, into a wide transverse loop 23, for the attachment thereto of the strap 24 leading to theaviator-harness.

On both the upper and lower sides of body 1, and registering with and enclosing bolt 5, I mount an antifriction thrust-bearing 21, see Fig. 1, and below the lower bearing, I mount a washer 22, having a lower roundededge hole, for the reception of a rounded shoulder on bolt 5 where it joins loop 23.

This gives added strength to bolt 5 where it is most needed.

The upper end of bolt 5 is threaded for the reception of a castellated nut 20, and said bolt is secured from turning by cotter-pin 20' through same, see Fig. 1.

Thus the aviator-harness is easily turned in any direction irrespective of the parachute position.

That the aviator may readily turn himself about in the air, irrespective of the parachute I providea sail or fan 26, comprising a light wire edge or form 26 covered with fabric, and a handle 27, and said handle may consist of an extra amount of edge-wire bent into handle shape, or a wooden handle may be driven on over the ends of the form-wire; said fan will also enable the aviator to maintain his position after turning.

Said sail or paddle the aviator may extend to one side, and, using the air as a fulcrum, easily turn himself to face in any direction at will. The sail is preferably held at arms length and slightly above the aviator, and, by varying the angle of incidence thereof, the motion of same through the air in descent will impart a sidewise slip or glide to the parachute, and by slightly twisting the paddle a rotatory motion will be imparted that will revolve the aviator on the swivel-joint so as to face in any direction; the action of the sail may be increased by making same larger, and the handle may be jointed or telescoped so as to go in the pack.

Said sail I stow in the parachute-pack, and attach a cord 27 to the handle 27, and the opposite end thereof may be attached to a suitable place on the hardness, to retain same at hand.

By putting the sail in the pack first on packing, it will in no way interfere with the withdrawal of the parachute and always be at hand, and yet out of the way of the aviator before launching.

Thus it will be noted that no special instructions are needed to use my devices. other than to properly pack the parachute in the container so it will readily come forth, as is ordinarily done. The sail being put in pack first will come out last. and after the para-- chute is pulled out by the pilot-chute. and

will be at hand by reason of its connecting cord.
