LIFE-SAVING APPARATUS FOR AVIATORS.

, Specification of Letters Patent. l atentgd Jan. 23,1912,

Application filed April 19, 1911. Serial no. 822,052.

To all whom it may concern:

Be it known that we, CHESTER A. JUDAH," residing at Mill Valle county of Marin, State of California, and

State of California, both citizens of the United States, have invented new and useful Improvements in Life-Saving Apparatus for Aviators, of which the following is a specification. This invention relates to a life-saving apparatus, and particularly to paraphernalia for the saving of the lives of aviators and aeronauts and passengers of aerial machines. The object of the present invention is to provide a light, compact, simple and readily released device for the saving of persons manipulating and traveling in aerial vessels; and to provide in combination a receptacle or casing adapted to inclose and restrain in a folded position a parachute, so constructed as to automatically unfold when released from the inclosingshell'or cover; and to provide in combination a life-saving paraphernalia having a protecting case or cover for an' automatically opening parachute and a harness structure adapted to be secured upon the body of aerial travelers.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a plan view of the apparatus?" Fig. 2 is a transverse'sectional View throu h 'the casing and showing the parachute 1n folded, restrained position. Fig. 3 is a diagrammatic view representing the folded automatically expansible selvage or edge of the parachute. Fig. 4 is a detail view showing the casing in part. Fig. 5 is a dia ammatic View representin the open un olded parachute. It is a desideratum to design and construct an apparatus for the saving of lives of persons operating and traveling in aerial machines; and particularly to-alford a light, substantial and automatically opening device which may be attached either to some portion of the aerial vessel cured to the back of the passenger and which may be released automatically or manually when occasion requires.

In attaining the objects of our invention we employ a parachute 2 of appropriate HENRY R. SANDER, residing at Oakland, county of Alameda,

' Attached to the or may be se-.

form, size and material which has attached to, or stitched in its circumferential edge or'selvage a series of sections 3 of some light elastic material, such as sprin steel or its equivalent. .The function of this elastic insertion is to automatically open to form approximately a curved edge whereby the parachute may be more readily rendered efi'ective during its descent. If these automatically opening elastic springs 3 were not employed, the ra id'ity with which the parachute would on old itself during descent would be so slow as, to hazard the life of the user in the .event that the apparatus was brought into use feet above the ground.

parachute 2 are suitable cords or ropes 4, which may be converged, and attached to 4 sirable construction and design, and which is adapted to be secured about the person only a few hundred a harnessor jacket of de-' of the wearer during flight in an aerial vessel.

' The parachute is adapted to be folded into small compass and its several expansible springs 3 are coiled, as indicated in Fig. 3, so that the parachute can be incased' in a flat, circular cover or per'and lower sections These shell sections 6 be hinged together .by

6 :and 7 respectively. and 7 are adapted to a suitable device, here represented as a pivotal ,piece 8 attached to the shell section 6, and a hook 9 open on its lower side, as at 10; to receive the plvot bar 8 attached to the complementaryshell or cover section 6. The several springs 3 attached to the edge of the parachute 2 are all. of considerable length andare adapted to be folded into small compass so as to occupy a comparatively small area approximately equal to the area of the shell sect-ions. When folded, as indicated in Fig. 3, the springs3 naturally tend to expand against the sides of the shell and when released quickly fly outwardly and form an open circumferential edge at the bottom of the parachute. When the folded parachute and its springs have been placed in position upon one of the shell sections it is held in a restrained position until the complementary cover section, as 6, is placed over the folded para-' chute.

For the purpose of keeping the shell casings closed after one has been swung about the pivot member 8, any suitable form of shell comprising uplatch or latching device may be connected to the. shell sections at a point approximately diametrically opposite the hinged members.

' This latch is shown at in Fig. 2, and to it ient place is connected a pair of cords 11 and 12, one of which may be attached to some convenient portion of the aerial vessel, and the other cord, as 12, can beled to the aviator so as to be within his reach.

In assuming his position in the aerialmachine, the aviator adjusts the-harness 5 about himself in a substantial manner. The cords or ropes 4', connected to the harness 5, are all sufficiently long to allow the incased parachute 2 to be mounted at some convenon the aerial apparatus which will permit theparachute to be opened and get away from the machine without danger of becoming entangled. i

In operation, should the use of the apparatus become necessary, the aviator may, if

he hastime,'deliberately pull the lanyard 12 to release the casing hook 10. The shell sections 6 and 7 will be automatically thrust apart about the open hinge partly by reason of the expansibility of the incased parachute and its spring sections 3 and also by positive actionof a. suitable spring 13 which is attached to the pivot member 8 and effective to thrust the opposite shell or cover 'outwardly about the pivot 8. In the event that the aviator is suddenly thrown out of the aerial vessel and does not have time to intention'ally operate the opening of the parachute casing and is thrown or jumps from the aerial vessel, the lanyard 12 will serve to open the casing or the other cord 11, attached to the hook 10 at one end and to a portion of the-vessel at the other-end will cause the shell to open as soon as sufiicient pull is exerted on the "cord 11 to unlatch the latch 10. Since the aviator has secured the I power,

ing capacity of harness 5 about himself and the ropes' l, connected to the harness, are led to the shell inas soon as sufiicient asstated, is appliedto the restraining cord 11 the latch 10 will be pulled and released allowing-the covers to automatically separate. The springs 3 in the selvage or casing the parachute,

circumference of the parachute will immediately fiyinto an extended position to almost instantly open the parachute to become effective as a support for the descending aviator.

In order to further increase the life savthe device the harness 5 embracing the aviator may be padded, as at 14, with a suitable structure capable of floating should the aviator be precipitated in water.

Having thus described our invention, what we claim and desire to secure by Letters Patent, is- I 1 1. A life saving apparatus for aerial travelers, comprising a parachute having attached to its circumferential edge a series substantially spread open the parachute,
