AEROPLANE.

Application filed March 12, 1919. Serial are. aeaeei.

To (all who-"Lit may concern:

Be it known thatl, WILLIAM D. VRIGHT, acitizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Aeroplanes, of which the following is a specification. c

My invention relates to a heavier than air flying machine in the form of an aeroplane 'of the monoplane type and the objects of my invention are first, to provide a supporting plane that is so shaped and constructed and so positioned relatively to the propeller that the air bank is of the highest efficiency,

second, to provide an aeroplane of this type in which the plane is so shaped, braced and supported that the danger of collapse is reduced to a minimum, third, to provide an aeroplane of this type in which the air current formed by the propeller is utilized to facilitate the support of the plane, fourth, to provide an aeroplane of this type which is narrow to facilitate landing .in narrow places such as a roadway, fifth, to provide an aeroplane of this type which is so shaped, positioned and constructed that there is little or no waste plane surface, sixth, to provide an aeroplane of this type 3 with aileronsof twisted. double curved form and positioned on a double angle to the plane which perform the double function of stabilizing the plane and maintaining its ping in making short turns and seventh, to provide an aeroplane of this type which is simple, and economical of construction, du-

- rable, easy to operate, eflicient, easily controlled and which will not readily dete- 40 riorate or get out of order.

With these and other objects in view as will appear hereinafter my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims reference being had to the accompanying drawings and tothe characters of reference thereon which form a part of this application in which i' Figure 1 is a top or plan view of my aeroplane complete.

equilibrium as well as preventing side slipgigure 2 is a perspective View thereof, an

Figure is a front view of one of the allerons minus the posts and guide wires and showing its relative position to this plane which is in fragmentary section.

S 1m1lar characters of reference refer to sunllar parts and portions throughout the several Views of the drawings.

The main body portion 1, propeller 2, supporting wheels 3, supporting plane 4. allerpns 5, rudder 6, stabilizers 7, rear supporting plane 8, and stabilizing vertical plane 9 constitute the principal parts of my aer l'pl lnlang.d I

e 0 y 1, pro eller 2 su ortin wheels 3, rudder 6, sta bilizer 7 and Fear sup porfiing plane 8 are of the ordinary or conventional type, the plane 4, however, is shaped as shown best in Fig. 1, provided with a pointed projecting portion 4; which extends forwardly toin front of the propeller andit is positioned asufficient distance above said propeller to permit the revolution of said propeller.

It is so positioned relatively to the body 1 that its rear end inclines toward the body as shown best ;in Fig. 2 of the drawings. The rear end consists of two V shaped members 43 which presents a fin surface to the a r when leaving the plane thus preventing a1r currents and eddies following the plane as in the conventional type. This plane is Slightly curved on opposite sides so that the points 4 are the high points and the plane recedes in every direction from these points 45. Secured to the lower surface in the middle of this plane is a vertical plane 9 which extends to the body 1 and tapering forwardly and backwardly as shown best in Fig. 2 of the drawings. This plane 9 serves as a stationary stabilizer. Mounted below each. of the corners 4 are the ailerons 5 mounted on supports 5 which provides an outward slant for the ailerons 5. These ailerons 5 are constructed in twist/ed form as shown best in Figures 2 and 3 so that they present a supporting surface to the air for side thrusts as well as maintaining the equilibrium of the plane. The plane 4; is provided with a net work of wires 4C for supporting the plane and maintaining it in 1ts shape and it is connected to and supported relatively to the body by means of the brace supports 4'.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, 1. do not Wish to be limited to this particular construction, combination and arrangement but desire to include in the purview f my invention the construction, combination and arrangement substantially as set forth in the appended claims.

It is obvious that with this construction,

there is provided an aeroplane of the monoplane type in which the front end of the plane extends in front of and abov e the propeller so that the upper surface of the plane is not subjected to an air current caused by the propeller nor is there an air pocket formed in front of the plane by the propeller but the front end of the plane is provided with an equal air bank which carries backwardly to the back of the plane and is not.disturbed by the propeller or action of the propeller by forming pockets, that the full force of the air from the propeller is utilized, as a bank of air for the plane, that the plane is so shaped that a maximum of air bank is provided for the surface of the plane, that the rear end of the plane is so shaped that the air currents and eddies do not follow the plane but. gradually taper out with the tapering points of the plane 4*, that the twisted and curved ailerons provide for the double function of maintaining the equilibrium of the plane as does the straight ailerons and also provides a side surface for supporting the plane against side shifting in turning, that the stabilizing plane 9 also reduces side shifting of the plane and forms a pocket for the air bank to assist in maintaining the equilibrium of the plane, that the air bank support divides and provides a main support from the point 4? to the two points l where it leaves the plane.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A monoplane, including, a main body portion, a propeller mounted on the front end thereof, a slightly tilted plane with its front end overhanging said propeller and its rear end formed into two spaced apart points, and a stationary vertical V-shaped stabilizing plane extending from said plane to the body.

2. A monoplane, including, a main body portion, a propeller mounted on the front end thereof, a slightly tilted plane with its front end overhanging said propeller and its rear end formed into two spaced apart points, a stationary V-shaped vertical stabilizin plane extending from said plane to the body and a doubly twisted ailerons pivoted on an angle to said plane on oppositely disposed sides of said plane-spaced slightly from said plane.

3. A monoplane including, an aeroplane body and a supporting plane, a stationary vertical V-shaped stabilizing plan'e extending from said plane to the body, and a doubly twisted aileron pivoted at an angle tosaid supporting plane and at an angle to said stabilizing plane on each side of said plane and spaced from said plane.

4 In an aeroplane of the class described, the combination with a supporting plane of a pair of ailerons, each mounted at opposite sides of said plane at an angle to the transverse and horizontal axes of said plane.

5. In an aeroplane of the class described, the combination with a supporting plane, of ailerons, each mounted entirely beneath the opposite sides of said plane so that the inner support is in advance of the outer support and at an angle t the transverse axis of its supporting plane.

In testimon whereof, I have hereunto set my hand at an Diego, California this 5th day of March 1919.

WILLIAM D. WRIGHT.
