PARACHUTE.

Specification of Letters Patent.

Patented Oct. 13, 1914.

Application filed June 4, 1914. Serial No. 842,986.

To all whom it may concern.

Be it known that 1, JOHN KRAJNY, a subject of the-Emperor of Austria-Hungary, residing at New Brighton, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Parachutes, of which the following is a specification.

The primary object of this invention is to provide a parachute adapted for belted attachment to the body'of a person for allowing gradual descents from great elevations and is especially adapted for alighting from a balloon or an aeroplane.

A further object is to provide a means readily worn by an aeronaut whereby he may safely effect a landing in the event of an accident to his aerial navigating apparaair.

A still. further object is to provide foldable wings positionable beneath the arms of the areonaut and a collapsible canopy positionable above his head and all of which are readily carried upon the body in their inoperative positions and ready for instant use invention is better understood, the same consists in the novel combination and arrangement of parts -hereinafter fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts thoroughout the several views :Figure 1 illustrates the device operatively positioned upon the body of an aeronaut, the device being illustrated in substantial central vertical section. Fig. 2 is a top plan view of the device detached with the top canopy removed and the covering omitted from one of the wings. Fig. 3 is a. perspective view of the belt and three ribs of each of the wing members, and Fig. 4 is a perspective view upon an enlarged scale of the link and spring connection of the ribs for the s de wings.

Referring more in detail to the drawings, the belt 10 is adapted to encircle the body of the aeronaut as best illustrated in Fig. 1, said belt carrying opposite side wings 11 after the manner of a parachute and positionable beneath the arms of the aeronaut while a collapsible canopy 12 is also attached to the belt.

The belt 10 is provided with body pieces.

13 positionable beneath the arms of the wearer and each having a shoulder strap 14: adapted to be secured around the wearers arms. The canopy 12 is of substantially balloon shape and may be formed of balloon fabric or canvas or other similar material and is provided with strengthening cords or ropes 15 passing around the same and connected to a bottom hoop 16 thereof, the said hoop being adapted to retain the moutt f the canopy in its open position. The low ends of any desired ones of the ropes 15 are ex,- tended as at 17 and secured to the shoulder straps and by which the canopy may be hung from the shoulders of the wearer positioned in its collapsed form at the back of the wearer and ready for use above his head to be filled with air by reason of the descent of the body in its downward movement. Y

The belt portions 13 are provided with spaced lugs 18 to which are hinged a plurality of ribs 19 similar to the ribs of an umbrella, seven of the same being herein illustrated positioned beneath each arm and forming side wings or parachute sections. The tops of said lugs 18 are connected by stop plates 24 which prevent an excessive upward pivoted movement of the ribs for preventing the wings from turning inside out during a descent. The ribs 19 are connected by pairs of pivoted links 20, while expansion springs 21 positioned between each adjacent pair of ribs tendto normally hold the ribs separated and the wings unfolded. It is to be understood that a flexible covering 22 is providedover each set of ribs being secured thereto and forming each wing with the appearance of a substantially semi-circular umbrella. The ribs of the wings are adapted to be closed as illustrated at one side of the device shown in Fig. 3 and .to be positioned depending from the belt and out of the way at the sides of the wearer, while the canopy as before mentioned, will depend deflated at the back of the wearer, the entire device being thus normallypositioned so as to offer no interference to the aeronaut in the manipulation of his air craft, but at the same time the device is ready for instant use whenever the wearer desires to descend or upon the occurrence of anyaccident; The wings may be retained folded by any'desired means but upon a descent of the wearer through the air, the said wings will automatically be opened by the air simultaneously with a filling of the canopy by the air and thus allowing a gradual descent while it will bGQSBBIl that if desired, the wearer may partially close either wing by lowermg either one of his arms and thus assist in directing his course of travel downwardly toward one side or the other. 'It isof course evident that the device is susceptible of other uses, such for instance as descending from high buildings or for purposes of jum ing for pleasure.

W hile the forms of the invention herein shown and described are what are believed to be referable embodiments thereof, it is nevert eless to be understood that minor changes may be made in the form, proportion and details of construction without departing from the spirit and scope of the invention as set forth in the appended claims.

What I claim as new is s 1. A device of the class described comprising a belt, shoulder straps secured to said belt, a collapsible canopy secured to i said shoulder straps, foldable umbrellashaped wings pivoted to said belt upon opposite sides thereof beneath said shoulder straps. I

2. A device of the class described comprising a belt, pairs of lugs carried upon opposite sides of said belt, ribs hinged to sa d lugs, pivoted links connecting the adjacent ones of said ribs, expansion springs between the adjacent ones of said ribs, a flexible covering secured over said ribs and stops for said ribs carried by the tops of said lugs.

3; A device of the class described comprising a belt, pairs of lugs carried upon 0pposite sides of said belt, ribs hinged to said lugs, pivoted links connecting the adjacent ones of said ribs, expansion springs between tlfe adjacent ones ofsaid ribs, a flexible covering secured over said ribs and stops for said ribs carried by the tops of said lugs,

shoulder straps carried by said belt, a balloon-shaped flexible canopy, a strengthening rope surrounding said canopy and having its ends extended and secured to said shoulder straps and a hoop secured at the mouth portion of said canopy.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN KRAJ NY.
