OLARS ERIK JOHNSON, or ELMnuRsT, ILLINOIS.

FLYING MACHINE.

Application filed August 4, 1924. Serial No. 729,878.

To all whom it may concern.

Be it known that I, OLARS ERIK JOHN- soN, a subject of the King of Sweden, residing at Elmhurst, in the county of Du Page and State of Illinois, have invented certain new and useful Improvements in Flying Machines, of which the following is a specification.

This invenion relates to flying machines in general, and especially to aeroplanes, and has for its object the provision of mechanism whereby the machine may be lifted from the earth without the necessity of extended travel in a horizontal direction on the earths surface. I

A further object is to provide a flying machine which shall be of improved construction and operation.

Other objects will appear hereinafter.

The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawings and described in the following specification, and it is more particularly pointed out in the appended claims. V

In the drawings- I Fig. 1 is a side elevation of an aeroplane having the present invention applied thereto;

Fig. 2 is-a fragmentary elevation of clutching mechanism forming a part of the present invention;

Fig. 3 is a vertical section on line 33 of Fig. 2;

Fig. 4 is a top plan View of the aeroplane wings and fuselage, with. parts of the machine omitted;

Fig. 5 is a somewhat diagrammatic front view of the aeroplane; and

Fig. 6 is a diagrammatic section of the top wing on line 66 of Fig. 4.

Referring more particularly to the drawings, the numeral 10 designates the fuselage of an aeroplane which may be of any approved construction, the one illustrated being provided with wings 11, 12 and 13. The wings 11 and 12 are of the usual form and operation. The upper wing 13 is provided with a central section 14 pivoted at 15 and provided with control lines 16 and 17. The lines 16 and 17 extend to a convenient position for operation by the driver and are I provided with the usual manipulating levers. The section 14 may be tilted upwardly, as illustrated in F'i 1,' or may be moved to a position par-a1 el with the remaining portion of the wing. ,A drive shaft 18 is arranged in the vertical plane of the main drive shaft which carries the propeller 19. The drive shaft 18 is provided with a propeller 20 arranged at an inclination, as shown.in the drawings. The shaft 18 is inclined to the horizontal so that the propeller 20 when operated will exert a lifting forcevtending to raise the aeroplane from the ground. The shaft 18 is provided with gears '21 operated by a shaft 22 which extends downwardly to a position adjacent thefmain drive shaft of the engine. The lower end of the shaft 22 is provided with a bevel gear 23 which meshes with a gear 24 on a short shaft 25. The shaft 25 is an axial alinement with the engine shaft 26, but separate therefrom. At the forward end of the shaft 25 a pair of arms 27 and 28 are attached, the

arms being fixed to the shaft 25. A bell crank 29 is pivoted to the arm 28, one arm of the bell crank having a clutch band 30 secured thereto, while the other arm is provided with a roller 31. The opposite end of the clutch band 30 is secured to the end of the arm 27, and the band extends about a pulley 32 which is fast on the shaft 26. A cone pulley 33 is splined on the shaft 25 in position to engage the roller 31, and is operated by a yoke 34 and a link 35, the link 35 being provided with any suitable lever mechanism. The upright shaft is provided with suitable roller bearings, shown at 36, for supportingthe end thrust thereon.

At the beginning of a flight, the. driver,

moves the cone pulley 33 forwardly so as to throw the bell crank 29 from inoperative to operative position, shown in Fig. 2. This will tighten the band 30 upon the pulley 32 and cause the shaft 25 to rotate in unison with the shaft 26, and thus drive the shaft 18 and the propeller 20, so that the propeller 20 will exert a lifting force at the beginning of the flight and raise the machine from the earth without the usual extended travel in contact with the earths surface. During this initial movement the section 14 is tilted upwardly soas to exert an additional lifting force on the machine. When the desired height has been reached, the clutch mechanism for the shaft 25 may be disengaged and the section 14 returned to horizontal position so that the plane will operate in the usual manner. While the wing section 14 is tilted upwardly the current of air from the propeller 20 will strike the lower inclined face of the section and exert an upward lift on second drive shaft arranged at an angle to' the horizontal, a propeller on said second drive shaft for exerting a forward and 'an' upward force on said flying machine, a wing for supporting said flying machine having the central portion thereof arranged to tilt into various angles relative to the remainder of said wing, and means for tilting said portion upwardly during the operation of said second-mentioned propeller.

2. The combination with an aeroplane having a substantially horizontal engine shaft and a propeller secured to said shaft, of an inclined shaft arranged in the vertical plane of said engine shaft, a propeller on said inclined shaft, an upright shaft geared to said inclined shaft, a'substantially horizontal shaft geared to said upright shaft and arranged in axial alinement with said engine shaft, clutch mechanism for securing said horizontal shaft to said engine shaft, a plurality of wings for said aeroplane, the uppermost one of said wings having a pivoted section, and means for tilting said pivoted section to assist in ralslng said aeroplane during the operation of said inchnedshaft and the propeller secured thereto.

3. A flying machinecomprising a pair of centrally disposed propellers arranged one above the other, the upper one of said propellers being inclined to exert an upward lift on said machine, a'wing member having a central pivoted section, means for tilting said pivoted section upwardly to receive the air current from said inclined propeller against the lower face of said section, and driving mechanism for said propellers arranged to permit said upper propeller to remain idle, said pivoted section being movable into registration with the other portions of said Wing when said upper propeller is idle.

4;. The combination with an aeroplane, of mechanism for facilitating rising thereof, said mechanism comprising an inclined propeller and a wing having a section thereof adjacent said propeller arranged to be inclined upwardly to receive the air current from said propeller, and driving mechanism for said propeller arranged to permit the same to remain idle for horizontal flying, said wing section being movable downwardly from its upward indlined position for horizontal flying.

5. In a flying machine, a main propeller, a second inclined propeller for assisting in rising, a wing having atiltable section adjacent said inclined propeller and having upwardly bent end portions, and driving name to this specification on this 11th day
