r FLYING MACHINE.

Application filed necembef 7, 1925. Serial No. 73,765.

This invention relates to .fiying machines of the combined type, said flying machine embodying certain features of the lighter than air flying machine and other features appertaining to the heavier v than air flying machine.

Theimain object ofthe invention is to provide a flying machine by means of which the machine may be successfully launched in the. air from a small field or place and also make a successful and safe landing under the same circumstances.

A further object. of the invention is to provide one or more lifting propellers of novel and efficient design combined with means for controlling air compressed andforced downwardly thereby so as to. lift the machine in a substantiallyvertical path and also enable the machine to be driven in actual flight.

Another object in view is to provide an aileron or reservoir adapted to be filled by the air under pressure delivered by the lifting propeller or propellers.

A further object in view is to provide valve controlled means in connection with flexible and expansible reservoirs or bags machine.

fuselage there arise standards 5 that provide a hollow upstanding frame. From the sides of the frame there are extended supports arranged in opposite pairs and may be indicated by the numerals 6 and 7. At their ends these supports are connected together by brace rods 8, the lower brace rods connecting the lower support 6 to the bottom I means 14:, longitudinally extending air containers 15. The ends of the inflated air containers 15 are pointed and suitable nieans, broadly indicated by the numerals 16 and 17, are connected With the upper and lower planes 10 and 11,.respectively and directed to the fuselage whereby the said planes and their air containers 15 are normally sustained on the supports 6 and 7 The means 16 and 17 are releasable to permit of the planes being swung to upward'angles with respect to the frame, as discuosed by the dotted lines in Figure 3 of the drawings. The reason for such swinging of the planes will be presently apparent and such planes may be brought to such angle positions through the medium of flexible elements 18 and 19 which are trained over pulleys on the frame and directed to the fuselage.

Arranged directly below the floor 2 of the fuselage there is a pipe member 20 which has its forward end closed, its rear end projecting beyond the rear of the fuselage and provided with a bell mouth 21. The pipe 20 rovides the traction propeller of the machine, as will presently be apparent. From the pipe 20 there arise equidistantly s aced spouts 22 and 23-23, respectively.

11 ofthe spouts communicate with the propeller spout or tube 20, and the said propeller pipe or tube 20, in alignment with the spouts 23, has its under face formed with funnel-shaped short pipe extensions 24, re-.

spectively. The passages between the funnel-shaped air inlets 24 and the propeller tube 20, are controlled by flap valves 25, and

means, broadly indicated by the numeral 26, is provided for simultaneously actuating all of the valves 25, the said means being operative from the fuselage.

Each of the spouts 22 and 23*23 has a funnel-shaped end or mouth 27. In the mouth of each of the spouts there is arranged a wind wheel 38 in the nature of a lifting propeller. The propellers 28 are dome-shaped and have the edges of their blades connected to a ring 28', and the shafts 29 for the said propellers are journaled in suitable bearings 230 in the respective spouts. On the lower and free end of each shaft 29 there is a gear wheel 31 in mesh with similar gears 32 on a common sl1aft 33 that is journalcd through bearing openings in all of the spouts. In each of the down spouts 22 and 2323 respectively. there is a downwardly inclined batlle plate 34 arranged directly above a paddle wheel 35. Each wlnd. influenced paddle wheel 35 has its shaft- 36 journaled in suitable bearings on the sides of the spouts 22 and 2%23, and on one end of each of said shafts there is a grooved wheel or pulley 39 aroundwhich is trained an endless belt that is also trained around the shaft wheel of a dynamo 40. The electricity generated by the dynamos is suitably stored and such electricity is employed for lighting the craft when the latter is in flight. for actuating or assisting in actuating certain of the movable or revoluble parts of the craft or when the craft is not in flight the generated electricity may be used for housc lighting purposes, for driving suitable machines, etc.

The forward end of the shaft 33 has arranged thereon a pulley wheel 41 around which is trained an endless belt 42 which is also trained around a grooved wheel on a shaft 43 of an internal combustion engine 44.

In the tubular propeller 20 there is a butterfly valve 45 that has a handle 46 ositioned to be operated by the occupant o the fuselage. By closing'the valve 45 air directed by the propeller 28 through the down spout 22 will find a passage through a valve controlled pipe 46 which leads to a storage tank 47. In the pipe 46 there is also a safety valve 48, and the storage tank is provided with a blow-off valve as well as a whistle 49. The air from the storage tank 47 may be employed for umintaining the air containers 15 fully inflated. the said air tank having flexible hose connections with the said air containers, and the passages through these connections 49' are controlled by valves. In addition to this the compressed air may be also employed for a number of other purposes, such for instance, as assisting in the operation of any of the parts of the ship. Also the tank 47 may contain therein a suitable chemical which will generate gas when air is mixed therewith, so that the ailerons will have no gas for retaining the same inflated as long as the ship is in motion.

At the rear of-the machine there is a hori' zontal rudder 50 and a vertical rudder 51, both of the rudders being suitably controlled from the fuselage.

In practice the engine 44 is started by a gas or gasoline charge in the usual manner so that motion is imparted to the shaft 33 which in turn imparts motion to the shafts 25) for revolving the propellers 28. The valves 25 are swung to fully open position to cause direct passage through the tubular air propeller 20. In this manner a direct vertical suction is created which raises the propeller to a desired elevation. Thereafter the valves 25 are swung to closedposition, causing the direct draft created by the propellers to be forced through the downspouts throughthe projecting propeller tube 20 and out of the bell mouth. 21 thereof, causing the craft to be propelled in a straight-ahead direction. The craft is lowered by opening or partly opening the valves 25. The rudders 50 and 51, of course, serve as guides for the craft and the tilting thereof assists in the raising and permits of the lowering of the craft. When the craft is propelled at such speed that the use of the engine 44 is no longer required, the

latter may be shut off and suitable means, such as the clutch means indicated by the numeral 52, may disconnect the engine shaft from the belt pulley. The air containers and the wings or planes, of course, stabilize and assist in the flight of the machine. As previously stated, electricity is generated and stored by the dynamos 40 and by closing the valve 45 air from the spout 22 will be stored in the tank 47.

hen the craft is in flight the planes 6 and 7 are swung to the dotted line position in Figure 3, so as to offer the least resistance to the air, and it is believed that the foregoing description when taken in connection with the drawings will fully set forth the simplicity and advantages of my construction to those skilled in the art to which such invention relates.
