I'LYTNG MACHINE OF THE AEROILANE TYPE.

Application filed December 12, 1927. Serial No. 239,556.

Myinvention consists of new and useful improvements in aeroplane flying machines of the heavier-than-air type. M flying machinel is of novel construction esigned for landing on land or water and being equipped with a central air dome and gas compartments insuring great buoyancy to the machine while in the air, and greater safety when landing. In the event of accident or motor trouble a gradual and safe descent is obtaingas compartments, and a flexible, folding air dome and means for raising the air dome when used for buoyancy purposes, or to be lowered in a foldin position when the machine is traveling t rough the air.

A still further object is the construction of a flying machine equipped with a combination of safety buoyancy devices and adapted to carry passengers or freight according to the capacity and character of the said flying machine, providing a machine niJore safe, useful, and commercially des1ra le..

WVith the above and other objects in view as will more fully appear as the description proceeds, it will be observed that this invention consists of novel construction, arrangements and combination of parts as hereinafter fully described, illustrated and claimed; it isto be understood, however, that numerous changes may be made in the construction of this invention, or the folding air dome,

which is centrally attached .to the upper por tion of the flying machine without departing from the spirit and intent thereof.

I attain these objects by means of the construction, mechanismand equipment illustrated in the accompanying drawings in which Figure 1 represents afront elevation of my flying machine.

Figure 2 represents a side elevation of said machine.

Figure 3 represents an enlarged cross section through the dotted line H. See Figure 2.

Figure 4a top plan view of said machine, having the central flexible folding air dome removed.

Figure 5 a longitudinal section of said machine through the dotted line y-y. See' Figure 3.

Figure 6 an enlarged cross section of the upper'wing through the dotted line 2. -2.

Figure 7 represents an enlarged perspective view ofthe folding air dome expanded and detached from the machine.-

Figure 8 a perspective view of said air dome in a downward folding position.

Figure 9 a front end plan view of the air dome showing means for raising and lowering said dome.

Referring to the drawings, similar numerals refer to similar parts throughout the several views, it bein understood that each side of my flying mac ine is constructed and appears the same, and all operating means is within the reach and control of the operator, whose position is under the air dome and at the rear of the central main motor.

Numeral V 1 designates .a pair of oblong metal tubes spaced apart, divided into three parts, andextending longitudinally the en tire length of said flying machine; numeral 2 designates a tight partition floor; 2 a tight partition ceiling by means of which floor and ceiling the oblong metal tubes are divided into three parts throughout their entire length; 2" .designates the machine framework rigidly attached to the. inner sides of the oblong tubes upon and within the said frame work and the oblong tubes, the wings and all other equipment is mounted in their respective positions; 3 landing wheels; 4 lower wings; 5 upper wing; 5 strengthening stay bolts; 6 gas chamber within the wings;- 7 fuel tanks in the lower portion of the oblong tube compartment; 8 passenger cabins; 9 gas chambers in the upper portion of the oblong tubes; 10 passenger seats; 11 cabin passageways; 12 central motor; 13 central propeller; 14; motors mounted on the top of the lower wings; 14 propellers; 15 vertical steering rudders; 16 steering arms attached to the vertical rudders; 16' tie rod between and connecting the vertical rudders; 17 side rudders; 1 8 steering arms attached to side rudders:

21 operators seat; 22 air dome chamber,

23 air dome bow frames; 24 flexible canvas constituting the air dome wlthin and attached to the bow frames 23; 25 a shaft extending.

longitudinally through the center of said machine, and at the lower part of the air dome; 26 a plurality of spools on said shaft; 27 hand wheel mounted on said shaft; 28 sheaves; 29 wire connection at the lower end of the bow frames;"3O wires attached at the lower end of the bow frames and extending-upward upon sheaves 28, and extending and attached to the spools 26, and by means of hand wheel 27 the air dome can be raised or lowered at the will of the operator; 31 steps at the door of the cabin entrance; 32 entrance door; 33 cabin windows.

It will be observed that in the construction I of this improved flying machine I employ two oblong metal tubes, spaced apart and rigidly attached to the spacing framework in vertical position. The lower part of said tubes is of shape similar to the bottom a boat. It is water tight and air tight, and constitutes the fuel tank designated 7 The central portion of said oblong tubes constitute passenger cabins, designated 8. The upper portion of said oblong tubes constitute buoyancy gas chambers, designated as 9. See Figure 3.

It will be observed further that the lower wings are rigidly attached to the outer sides of said oblong tubes, and the upper wing is ri idly attached to the inner side of said tu es, and further attached to the upper portionof the lower wings; said wings being spaced apart as shown in the different views.

It will be still further observed that this flying machine is equipped with an air dome which covers the entire space between the oblong tubes, and extends longitudinally nearly the entire length thereof, and when expanded extends to the upper wing, and

- when closed downwardly it rests on the frame brackets in a folding position as shown by H the dotted lines, F igures 1, 3 and 9. It is to "be understood that this air dome frame is lined with air tight, flexible canvas,-and is raised and lowered by means of hand wheel 27, mounted upon shaft 2?, and by means of wire connections therefrom, as shown in Figures3 and 9. The operator has full control in the raising and lowering of said air dome, which when in the expanded position adds great buoyancy to a flying machine, especial y when descending.

It will be observed still further that by inflating the upper chambers 9 of the oblong central tubes, and the inflating of the wing chambers 6 with gas, helium' preferred, a still greater buoyancy is obtained.

I am aware that gas mfiatlng means and not limited thereto, but that variouschanges ma be made in the construction, proportions an arrangement of parts, without departing from the scope of my invention, as defined in the appending claims.

Having described my invention what I claim as new and. desire to secure byLetters Patent is 1. A flying machine of the character described, consisting of two oblong tubes spaced apart, being rigidly attached to the sides of a central framework, the lower portion of said oblong tubes being in shape like unto a boat, and adapted for fuel tanks, a central passenger cabin, within said oblong tubes adapted for carrying passengers, an upper chamber within said oblong tubes adapted to retain gas for buoyancy purposes, wings spaced apart and rigidly attached to the sides and extending crosswise over the longitudinal oblong tubes, chambers within said wings adapted to retain gas for buoyunto a boat and adapted for fuel tanks, a

assenger cabin within said oblong tubes a apted for carrying passengers, an n per chamber within said oblong tubes a apted to retain gas for-buoyancy purposes, wings spaced apart and rigidly attached to the sides and extending crosswise over the longltudinal oblong tubes, a central foldin air dome mounted upon theframework and extending longitudinally between the oblong tubes for buoyancy purposes and means for raising and lowering said dome as shown, and for the purposesset forth.

u 3. The combination in a flying machine, including two oblong tubes spaced apart by framework, each divided into three parts,

providing fuel tanks, passenger cabin and gas uoyancy chamber, a plurality of wings at tached toand extending crosswise-of said oblong tubes chambers Within said Wings I adapted to retain gas for buoyancy purposes, a central folding air dome mounted on the framework and means for lowering and raising said dome for buoyancypurposes, a plurality of steering'rudders attached to therear end of the longitudinal tubes, and means for operating said rudders for steering purposes andmotor means for propelling said flying machine substantially as described and for the purposes set forth.
