PERRY L. JORDAN, OF WASHINGTON, IOWA.

Application led January 14, 1921.

To all 107mm t may concern.'

Be it known that I, PERRY L. JORDAN, a citizen of the United States, residing at Washington, in the county of Washington and State of Iowa, have invented new and useful Improvements in Life-Saving Means for Aeroplanes and other Airships, of which the following is a specification.

The obj ect of my present invention is the provision of efficient means designed more especially, though not necessarily, for use in aeroplanes, and constructed with a view to enabling an aviator in the event of the aeroplane becoming disabled, to bring about the launching of himself in connection with a parachute into the air and clear of the aeroplane so that the descent of the aviator to the earth will be slow and safe.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part hereof Figure 1 is a top plan view, partly broken away of an aeroplane equipped with my improvement.

Fig. 2 is a fragmentary vertical longitudinal section of the same.

Figs. 3 and 4 are transverse sections taken in the planes indicated by the lines 3 3 and 4 4, respectively, of Fig. 2.

Fig. 5 is an enlarged detail view illustrative of the manner in which the shoes of the parachute are `arranged relatively to the guide rods.

' Fig. 6 is an elevation showing the position that the parachute and the aviators seat assume substantially to the discharge of the parachute from the aeroplane.

Fig. 7 is a detail perspective hereinafter explicitly referred to.

Fig. 8 is a detail diametrical section illustrative of the association of the guide rods and dome-like portion of thc parachute.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

In general the aeroplane includes a fuselage 1 and is otherwise of the ordinary well known construction.

In furtherance 0f my invention the fuselage 1 is provided with a tubular casing 2 which extends throughout the major portion of the length of the fuselage and is entirely open at itsrear end, Fig. 2.

Within the tubular casing 2 are arranged Specification of Letters Patent.

Serial No. 437,249.

longitudinal track rails 3, and arranged in engagement with and adapted to travel on said rails 3 are circumferentially grooved wheels 4, mounted in antifriction bearings in a frame 5 that is under certain conditions freely 4movable in the tubular casing 2 `toward and through the rear end thereof. At its opposite sides the frame 5 is provided with trunnions 6 which are journaled in the side portions of a bail 7 for a purpose hereinafter set forth. Fixed with respect to the frame 5 is an aviators seat 8, and carried at one side of the said seat is a cam lever 9. Also carried at the said side of the seat 8 is a vertically movable rod 10 having at its upper end a head 11 opposed to the periphery of the cam portion of the lever 9. At 12 the said rod 10 is provided with an abutment. It will also be noted that the rod 10 is movable rectilinearly in guides 13, and that a spring 14 is interposed between the lower guide 13 and the abutment 12 in order to hold the head 11 of the rod 10 under yielding pressure against the cam portion of the lever 9. At its lower end the rod 10 is arranged to bear downwardly against the arm 15, fixed to a rock shaft 16 which rock shaft is provided with other arms 17. The said arms 17 are connected through the medium of links 18 with arms 19 on rock shaft 20. The said rock shafts 2O also carry retaining hooks 21. Manifestly when the cam lever 9 is manipulated to depress the rod 10 against the action of the spring 14, the

rock shafts

16 and 20 will be rocked about their axes, and the hooks 2l on the rock shafts 2O will be swung upwardly for a purpose hereinafter set forth. As clearly shown in Fig. 1 the hooks 21 are normally arranged in keepers 22 at the outer side of doors 23 which are hinged at 24 to the fuselage and are equipped with retractile springs 25 which have for their function to swing the doors into the open positions shown by dotted lines when the hooks 21 are disengaged from the keepers 22 in the manner before described. Interposed between and connected to portions 26 of the fuselage and the doors 23 are cables 27 which serve to limit the outward movement of the doors 23. It will be apparent from the foregoing that while the aeroplane is in Hight the aviator is enabled in the event of accident to quickly release the doors 23, whereupon the said doors vwill be promptly opened and a strong head of air will be admitted to the forward portion of the tubular casing 2. I prefer to provide the rod at its lower end with a hook 10X that is movable in an eve l1X on a fixed bar 12X to hold the seat 8 and the parts movable therewith against longitudinal movement relatively te tie tubular casing 2 of the fuselage. Manifest-ly when the avia-tor desires to release the seat 8 from the bar l2X to permit of rearward movement of the seat 8 and the parts movable therewith, it is simply necessary for the aviator to manipulate theA lever 9 so as to move the rod 1 0 downwardly and carry the hook l0*V out of engagement with the eye 11X of the bar 12X; the said eye 1lX constituting a keeper. This, however, is not of the essence of my invention.

Disposed in a collapsed state in the tubular casing 2 in rear of the frame 5 and the aviators seat 8 is a parachute 30 having cables 31 which are connected to a body 3.3. rllhe said body 33 is swiveled at 3d on the stem 35 of thel before mentioned bail 7. IF rom this it follows that when the doors 23 are opened, and the strong head of air is led into the forward portion of the tubular casing 2 the parachute 30 will be powerfully ejected from the rear end of the tubular casing 2, and will carry with it the bail 7, frame 5 and driver seat 8, whereupon the frame will `assume a pendent position as appears in F ig. 6 so as to avert discomfort to the aviator incident to his descent to the ground with the assistance of the parachute.

At a point above the position equipped by the aviator in' the normal operation of the aeroplane, the tubular casing 2 is pro vided with an appropriate transparent door et() designed to enable the aviator to readily gain access tothe seat 8, and also to render it convenient for the aviator to observe what is above the aeroplane.

Arranged within theV tubular casing 2 are guide rods which are adapted to hold the parachute 30 in proper arrangement relatively to the wall of the casing 2, and are also designed in combination with shoes 5l to preclude tangling of the folds of the parachute in the tubular casing' 2.v By virtue of the construction of the shoes 5l as illus trated the said'shoes which are carried by the parachute, Fig. 6, are adapted to slip oil the guide rods 50 and separate as soon as they reach the rear ends of the guide rods, whereupon the parachute will effectively open. In thisv connection it will be apparent that the guide rods 50 serve somewhat after the manner of hinge pintles when the shoes 5l are within the tubular casing 2, and the separation of the shoes 51 only takes place after the said shoes move rrearwardly off the guide rods 50.

As will be observed by comparison of Figs. 2 and 6 the parachute 30 is provided with a dome portion 60, and .in said. dome portion G0 is a light frame work 6l. By virtue of this provision it will be manifest that the air will afford but little resistance to the ejection of the parachute from the rear end of the tubular casing 2.

For the sake of increased strength I prefer to reinforce the rear end of the frame work 6l with hooi s 70 of aluminum or other appropriate material.

In order to efficiently support the domelile portion of the parachute in the fuselage of the aeroplane, and to assure the prompt separation of the frame work 61 from the guide rods 50 I prefer to employ the construction shown in Iig. 8. By reference to said figure it will be noted that the guide rods 50 have sockets 80 in their rear ends in which springs 8l are housed, and that the longitudinal rods of the framework 6l are reduced, as indicated by 82, and are arranged in said sockets and against said springs. From this it follows that under normal conditions the dome-like portion 60 of the parachute will be adequately sup-V ported relatively to the fuselage; also that the initial rearward impetus of the parachute will be assisted by the springs 8l.

It will be apparentfrom the foregoing that my improvement affords a reliable leans to enable an aviator to safely descend to the ground in the event of the aeroplane or other airship becoming disabled. In this connection it will be appreciated that by virtue of the parachute being properly folded and resting close to the vwalls of the tubular casing` inflation of the' parachute and the 'powerful ejection of the same from the tubular casing when the portions 23 are opened will be assured. l

It will also be apparent from the foregoing that little difficulty will attendthe positioning of the parachute and the aviators seat in the tubular casing 2; it being simply necessary to move the seat andthe sea-t frame forwardly to proper position in the tubular casing 2, and tofposition the shoes on the guide rods and move theshoes to proper position within the tubular casing 2, when the parachute. will be held adjacent to the wall ofthe tubular casing 2, and

Vtangling of any part of the parachute will be averted. I would also have it understood here that the swiveled connection of the head 33 to the bail 7 is calculated to preclude tangling of the cables of the parachute so that the parachute will surely open when the same is subjected to the weight of the aviator in the air.
