CARL D. F AHSEL, DECEASED, LATE OF NEW YORK, N. Y., BY NELLIE FAHSEL, ADMINIS- TRATRIX, OF NEW YORK, N. Y.

DIRIGIBLE Ainsmr.

Specification of Letters Patent. Patented J an. 14, 1919.

Application filed May 8, 1917. Serial No. 167,222.

To all whom it may concern Be it known, that I, NELLrn FAHSEL, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, United States of America, administratrix of the estate of CARL D. FAHSEL, deceased, late a citizen of the United States and a resident of the city of New York, borough of Manhattan, in the county and State of New York, United States of America, as by reference to the duly authorized certificate of the clerk of the Surrogates Court of New York county, N. Y., will more fully appear, who did in his liftetime invent certain new and useful Improvements in do hereby declare the Dirigible Airships,

and exact dcfollowing to be a full, clear, scription of said invention.

This invention relates to aerial navigation and has particular reference to air craft which preferably include one or more gas bags for the purpose of buoyancy and which also will be provided with means for steering and stabilizing.

Among theobjects of the invention is to provide an airship of the character above set forth which will embody in its construction'a parachute effect whereby it will be impossible for a serious disaster to result because of the failure of any of the mechanism or the bursting of any or all of the gas bags.

A further object is to improve this class of devices in such a manner as to provide for better'control of the machine while in operation and to increase the safety to the occupants thereof.

The foregoing and other objects of the invention will hereinafter be more fully describedand claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a side elevation of a preferred embodiment of this invention;

Fig. 2 is a bottom plan view of the same;

Fig. 3 is a vertical longitudinal section;

Fig. 4 is a vertical transverse section on the line 44 of Fig. 3;

Fig. 5 is a partial plan view of one of the planes, partly in section on the line 5-5 of Fig. 4; and

Fig. 6 is a perspective diagram of a portion of the controlling mechanism.

This airship in its preferred form comprises an upwardly arched shell or casing 10, of any suitable form in cross section, and having an open bottom 11. This shell may be constructed in any suitable manner including a pair of spaced envelops 12 and.

13, the latter being Within the former and both terminating in substantially the same plane at the bottom. These envelops will, of course, be constructed of suitable light thin material, but of sufficient strength for their purpose and the space between them will insure perfect ventilation of the gas bags described below, by the provision of proper circulation of air within the outer envelop all of which will be better understood as this description progresses.

At 14 are shown diagrammatically a series of gas bags of any usual or preferred construction carried within the concavity of the shell 10. These gas bags are de signed to be independently filled and the gas thereof controlled by anyusual or well known means, such means parse constituting no part of this invention.

At the front end of the airship is constructed a compartment 15 for the purpose of housing the propelling motor, the controlling mechanism and the pilot or other persons in command of the machine. Operating directly from and in front of said compartment is a propeller 16 of any suitable nature. At the rear end ofthe machine or baggage is shown suspended centrally from the bottom of the airship and the same preferably consisting of a boat-shaped construction and equipped with self-contained propelling and steering mechanism whereby passengers contained therein may be conveyed to a place of safety in the event of the airship alighting upon the surface of a body of water. The cabin 20 may, if de sired, be designed to be detachable from the airship in cases of emergency and be provided with means for making it watertight should it become temporarily submerged. Under normal conditions one or more gangplanks 21 may extend from the cabin 20 to a walk 22 leading from one end of the airship to the other on one or both sides preferably adjacent the lower end of the inner envelop 13, whereby passengers carried by the cabin 20 or other persons connected with the air craft may pass freely from one part'of the machine to another.

On each side of the machine and pivotally connected thereto adjacent the lower edge is 'a stabilizing device 23. As herein shown,

these devices on opposite sides are similar to each other and each comprises a pair of planes '24 extending outwardly in parallel planes from a wall 25 which carries a hub 26 through which the device is pivoted upon a short shaft 27 extending outwardly from the side of the shell. These stabiliz- 'ing devices 28 are adapted to be tilted 0n the horizontal pivots 27 by any suitable mechanism such, for instance, as that illustrated in Fig. 6 and including a flexible connection 28 having its ends secured to a bar 29 carried by the wall 25. The intermediate portion of each connection or cable 28 is guided over a suitable arrangement of di rection pulleys 30 and operates around a wheel 31 in the 'pilot house 15. As indicated in Fig. 6, the rotation of the Wheel 31 in "either direction will cause a corresponding operation of both of the stabilizing devices. The planes 24 are intended especially for the purpose of controlling the elevation or descent of the airship and hence are operated in unison, the reverse inclination of these devices not being necessary because of the nature of the shell 10 and the buoyant means contained therein.

Great difficulty has, heretofore been encountered in the practical operation of diri'gible balloons with respect to the irregular expansion or contraction of the several gas bags, and I overcome such difiiculty in this instance by the double envelop construction of the shell and also by providing ameans whereby the inner envelop may be cooled, if necessary, by spraying .the same with water. To this end I, provide a pipe 32 which leads from the rear compartment 17,

where, the water, may be carried, upwardly and forwardly toward the pilot house 15,

copies Of'thl-El patent may be obtained for five cents each, by addressing the Washington, D. G.

such pine being provided with spraying perforations 32 throughout its length and directed laterally so that the water may be sprayed substantially throughout the surface of the inner envelop. Another pipe 33, for the conveyance of liquid fuel or the like from the storage compartment 17 to the pilot house 15 may be provided and extend parallel to the aforesaid pipe 32 or in any other suitable manner.

An airship constructed in accordance with the foregoing description will insure that in the event of the stoppage of the propelling and steering devices from-any cause or the escape of buoyant gas from any of the gas bags 14 it will settle toward the earth at a safe velocity, and by reason of the form and construction of the shell, the airship ries of gas bags, a shell comprising inner and outer spaced envelops in'clo-sing said gas bags and insuring thorough ventilation and uniform temperature thereof, means to control the operation of the airshi andimeans to spray a cooling liquid upon the inner envelop of said shell. v v

2. The herein described airship comprising a shell having inner and outer spaced envelops, said shell having an open bottom, a series of gas bags within the shell and abutting substantially against the inner envelop, a perforated pipe leading substantially from one end of the shell to the other whereby a cooling liquid may-be sprayed upon said inner envelop, and means to control the operation of the airship.

3. The herein described airship compris ing a buoyant body including an upwardly arched open bottom shell including a pair of inner and outer spaced envelops, compartments at the opposite ends of said body, and a fuel connection from one compartment to the other extending along the shell between said envelops.
