JOSEPH B. STRAUSS, OF CHICAGO, ILLINOIS. I

FLYING MACHINE.

Application filed August 1, 1924. Serial No. 729,453.

This invention relates to flying machines and has for its object to provide a new and improved machine of this description. The invention has as a further object to provide a flying machine construction wherein the weight of the machine is reduced without de creasing its strength or ability to resist the stresses to which it must be subjected.

The invention has as a further object to reduce head air resistance. The invention has as a further object to provide a construction which increases the safety of operation in flying and in landin The invention has other objects which are more particularly pointed out in the following description.

Referring now to the drawings,

Fig. 1 is a plan view of one form of flying machine embodying the invention.

2 is a front View of the device shown in Fig. 1.

3 is a plan View of the incline member.

Like numerals refer to like parts throughout the several figures.

Referring now to the drawings, I have shown the construction wherein there is a body 1 having a wing 2. Associated with the wing are the two inclined wings 3 and f. These wings are connected together at the bottom by the member 5 and wings 8 and 4 and member 5 are preferably integral. The member 5 forms one side of the triangle, the other side being members 6 and? which extend upwardly and connect with the wing 2, thus forming a triangular trusse-d construction uniting the wing 4: and member 5 at the center with the wing 2. The wings 3 and 4t engage the wine; 2 near its ends, and are preferably tapered from the middle toward their ends, as illustrated in Fig. 3. hen such wings are tapered the extreme ends are preferably flared out as shown at 8, Fig. 3, so as to give better support to the ends of the Wing 2. These wings 8 act in taking lift and also act as struts to strengthen the wing 2. Stating it in another way, these inclined wings, when acting to take lift, that is when acting as lifting members, take transverse stress, and when acting as frame members in strengthening the wing 2, they take longitudinal stress.

This, of course, gives simplicity and definiteness' and eliminates adjustable elements. It also provides great safety becausethe mem' bars are all rigid, simple members. It further eliminates ambiguity and high stress and it provides a lighter construction, the material being arranged properly to take care of the stresses. It will be noted also that these win gs 3 and a are straight linewings'.

I also provide means for insuring greater safety in landin To accomplish this, I provide at the front a single largelanding wheel 9 which projects up into the body 1 of the iachine. This reduces the head resistance and permits. a wheel of large diameter to be, 6r used, as for example, a wheel five or'siir feet in diameter which goes over irregularities in the ground better, and which, because of its projecting into the body, still gives less head air resistance. I also prefer to provide at the rear two landing wheels :10and 11 placed on opposite sides, as illustrated; As shown, these landing wheels areconnected with the fins 10 and 11 and are outside of the limits of the body, said fins are strengthened transversely to carry the load coming on the wheels. This construction takes the weight better and enables the securing of a better landing with greater safety.

The inclined wings 3 and 1 are preferably provided with openings 3 and 41 so that the operator may see therethrough in observing the portion over which he is flying.

I claim:

1. A flying machine comprising a body, a wing connected therewith and projecting in opposite directions therefrom, two inclined wings below said wing and engaging the wing near the ends thereof, said inclined wings tapering from their adjacent ends toward their outer ends, the ends of said inclined wings where they engage the wing being enlarged.

2. A flying machine comprising a body, a wing connected therewith and projecting in 9 opposite directions therefrom, two inclined wings below said wing having enlarged upper ends and an intermediate: portion less in width than the ends and having their ends extending upwardly and engaging the wing,

I the ends of said inclinedwings which engage the wing extending substantially across the width of the wing.

3. A flying machine comprising a body, a wing connected therewith and projecting in opposite directions therefrom, two inclined wings below said wing and having their ends extending upwardly and engaging the wing,

I the ends of said inclined wings which engage the wing being enlarged and extending substantially across the width of the wing, portions of said inclined wings between the ends thereof being smaller in width than the width of the wing. Y

4. A flying machine comprising two wings at an angle to each other, one of said wings tapered toward its end and connected at said end to the other wing, said tapered wing pro- Vided with an enlargement where it joins the other wing to secure lateral stiflness.

5 A flying machine comprising a body, an upper and lower wing spaced apart at their center and merging near their extremities,

triangular truss member connecting them at the center, said member with the wings forming a triangular truss system, said lower wings each having enlarged portions connected together by smaller portions.

.6, A flying machine comprising a body, an upper w ng projecting onppposite sides of i said body two lower inclined wings having their ends engaging the upper wing, a connect on between the ad acentends of the lower wings, two inclined membersengaging said connection at, separated points and connecting with the uppe wing- Signed at Chicago, county of Cook and State'of Illinois, this 25th day of July, 1924:.
