AEROIPLANE.

Specification of Letters Patent.

Patented Aug. 22, 1911.

Application filed July 30, 1910. Serial No. 574,697.

To all whom 'it may concern:

Be it known that I, PAUL SCHNEIDER, a subject of the German Emperor, and resident of Tegel, near Berlin, Germany, have invented a certain new and useful-Improvement in Aeroplanes, of which the following is a specification.

This invention relates to improvements in aeroplanes and consists in arranging around a vertical shaft elastic umbrella-shaped sup porting surfaces separated by intermediate air spaces, the arched vertices of which surfaces are arranged externally of the axis of the vehicle so that equilibrium may be obtained in all directions of flight.

The supporting surfaces may be rigidly arranged about a shaft arranged in the vertical axis of the aeroplane and a number of them may also be capable of actuation. They thus offer to the air resistances in all directions of flight a symmetrical form with the center of gravity of the vehicle constant by reason of the arrangement of all mechani-' cal parts below the center of gravity of the supporting planes. i

The machine is brought into position ready for flight in the direction of the arrow in Figure 3 by adjustment of the vertically rigid planes at a suitable angle to the arrow in Fig. 1, the parts of the supporting surfaces inclined to the direct-ion of flight under the influence of the propeller imparting when slightly inclined a slow flight and when more inclined a faster flight of the vehicle.

The motive power for the aeroplane can also be employed to increase its buoyancy by imparting a positive vibrating motion to the separate parts of the planes. This however is not a necessity and is only to be considered as an auxiliary means for increasing the buoyancy during flight.

The alterations in direct-ion of flight are effected by movement of an aileron on either side, the return to position of which takes place after completion of the turning movement while for direct flight under the rear supporting surfaces over the propeller is arranged a keel plane.

The invention is illu: t-rated in accompanying drawings in which Fig. 1 is a view of the invention showing the planes inclined relatively tothe direction of flight. Fig. 2 is anelevation of the frame showing the supporting mechanism of the planes. Fig. 3 isa plan of the planes with the lever mechanism. Fig. 4 is a plan of the framework for the plane frame.

Referring to the drawings, on the resilient frame f rests the rigid bottom frame I) and with this is rigidly connected the fixed frame G for supporting the motor M and actuating mechanism. The upper end of this frame is formed by the top plate 39 with the guiding mast on said plate serving to hold the plane frame concentrically. The top plate p of the motor frame G serves also as a rigid bearing for the parts t and t of the frame work for the planes which areheld by steel trusses z to the bottom frame 6 so that the rigid connection of all the above mentioned parts is insured.

In the present arrangement the plane body consists of 8 double arched planes of which the planes S and S on each side of the aeroplane are used in place of the hith erto well known supporting surfaces while the plane H- serves as an elevator, K as a keel and the intermediate planes Z to Z in proportion to their dimensions increase the lifting effect of the planes.

The plane frames S to S are provided with inner ends 72. formed as levers and which are pivotally connected by members 9 (Fig. 2.) at 9 (Fig. 3.) with the heads of the framework rods t and at g (Figs. 2 and 3.) with the bush 0 adjustable on the guide mast m.

In order to increase the buoyancy of the aeroplane during flight the lateral planes S and S are positively vibrated by means and by means of the foot 01. of the bush 0 sliding therein, connecting wires d serving to tension, the planes (Fig. 3.) in this case being guided from Z and Z direct'to Z and Z The keel 70 arranged beneath the plane K serves to insure direct flight which is departed from by the motion of one of the two similar lateral planes a; or y so that on the side to which it is turning, a suitable a'ir resistance from the direction of flight comes into operation during the movement.

The motor M mounted in the frame G has a shaft on which the air propeller P is directly mounted while the parts 1 and e of the driving mechanism may be actuated as required in order to effect simultaneous positive motion of the lateral sails S and S of a cam edriven by the sprocket wheels 1" Having now described by invention I declare that what I desire to secure by Letters Patent of the United States is:

In an aeroplane, the combination with a supporting frame work, and propulsion means carried thereby, of an, elevating plane and a keel plane radiating in opposite directions from said frame-work, vibratory supporting planes radiating in opposite directions from the frame-work, meanscarried by the frame-work for vibrating said planes,

and supporting 'lanes radiating from the frame-work whic are disposed intermediate the planes aforesaid.

In testimony whereof I have signed my 15 name to this specification in the presence of two subscribing Witnesses.

PAUL SCHNEIDER.
