To all whom it concern:

Be it known that I, Anonrnnf CLI'JMENT, a citizen of the Republic of France, residing in Devallois-Perret, Seine, France, have in-- vented certain new and useful Improvements in Dirigible Ae'rostats and the Like, of which the following is a specification.

Experiments made with dirigible balloonsw that there is room for a system meeting all requirements. It is in this spirit that he has devised the improvementshereinafter described which as a wholeconstitute. a novel dirigible balloon presenting a character of novelty both as regards its outward form and as regards the special structure of its reinforced. beam forming a keel, and also as regards certain devices which will hereinafter be described with reference to the accompanying drawing, in which F1gure 1 is an elevation. Fig. 2 is a lower plan. view. Fig. 3 is a section through the main beam of a balloon constructed in acoordance with the. invention. Fig. at is an elevation showing the method of anchoring the balloon, to the ground, the openwork net i Fig.

are front elevations of the openwork part1 which is laced and buttoned to the reinforced beam forming a keel, which is itself covered. Fig. 5 is a plan view showing the arrangement of the car and of the wings. 6 is a rear elevation, and Figs. 7 and 8 tions of the gas balloon and of the air bal- Icon or ballonnet respectively. Figs. 9 and 10 are detail, large scale, views similar to Figs. 3 andl respectively.

I Referring to Fig. l, a is a reinforced beam or girder -torming a keel, approxi mately triangular, fitted to the lower axial. part of the balloon and extending throughout the whole or a part of its length and conforming to its shape. This beam is con nected with the balloon by means of an openwork net b (Figs. 4 and 6) along straight Application filed February 6, 1909. Serial Ito/476,515.

or curved seams, with considerable supporting surfaces between the respective scams 0 and the corresponding tangential lines 41 above which the seams are located. This net necessarily serves to reinforce the balloon and at the same time maintains tangential contact notwithstanding the incessant fluctuations due to the internal pressures, which are unstable.

e and f are unvarnished elastic partitions which may be openwork at the bottom as regards the partitions of the gas balloon and at the bottom and at the top as regards those of the air ballonnet, as indicated at a: in Fig. 7 and at a: and y in Fig. 8, and which are intended to render impossible sudden displacements of the gas toward the front or toward the'rear,-and to counteract the effects of inertia of the gaseous massv in starting and in stopping. it

y and h are wings horizontally displace abe and pivoting around a vertical axis (see Fig. 2) either together of independently and in such a manner that in landing they can fold back against the keel fore or aft of their axis.

As in the applicants opinion a dirigible balloon cannot come to ground in bad weather without risk of damage, the elongated keel (the front and rear of which are higher than the lower part of the balloon) is utilized for providingtwo points of support A and B. From the point A leads a cable which is anchored to the ground at the point T.- At the point C of A T there is a pulley i. A cord passes horizontally from the point D on the car over the pulley z to E, where it branches out int-p two cords and rises,' being fixed on either side of the keel at B and B.

The wind tends to lay the balloon upon the ground, but as the angle T A B is indoformable, the balloon inclines from the rear, forms-a kite and rises under the influence of the same wind into its original position,

- its nose to the wind and the whole forming a vane tending to present its minimum resistance or surface to the storm. Owing to this arrangement the height may be selected in accordance with the violence of the wind,

the aerial currents or the topographical conditions.

By placing a pulley at T the cable A T may be brought as far as the car D. In this case by means of a winch for example, the

ballobn may be brought to ground by haulihg a part of C T D upon the car, thus imithe wings which insures eflicienoy and a better result from the motive power.

In the case of a beam extending from one end of the balloon to the other, this beam may terminate in front in a spherical cone of rigid material protecting the point of the balloon which would be fitted freely therein.

The ear carrying the motor, the propellers and the aeronauts, is. suspended in any known or suitable way and enables the propeller or propellers to be located. in front or behind, laterally at various heights and even between the keel and the car.

As appears more clearly in the detail views, Figs. 9 and 10, the bolt rope b ofhemp is sewed to the balloon along 0; it sur rounds the girder a and is laced upon this girder by means of cords L. lhe suspen ders s are attached directly to the girder and pass through the bolt rope I) through special openings t providedt'or the purpose.

xVhat I claim and desire to secure by Let ters Patent of the United States is 1. A dirigible aerostat comprising a balicon with a longitudinally curved lower profile, a beam on the underside of the balloon, and a net for attaching said beam to the balloon, said net engaging the lower partof the-beam so as to support the latter within it and being fastened tothe sides of the balloon along lines above the lines at which it is tangent to the balloon, so as to engage the balloon over a surface which is variable with the interior fluctuations of the balloon.

2. A dirigible aerostat comprising a gas balloon containing an air ballonnet located in the lower part of the balloon, flexible permeable partitions 0 between the balloon and the ballonnet, and flexible apertured partitions f across said ballonnet,-s-:aid partit-ions tending by their flexibility and per-' Inea-bilit-y to neutralize the efi'ects of inertia in starting and stopping and to prevent injury by sudden forward or backward move ment ofgas.

In witness whereof, I have hereunto signed any name in the presence of'two sub} scribing witnesses. v
