CARRIAGE FQR FLYING MACHINES.

Application filed April 2, 1923, Serial No. 629,414, and in Germany May 3, 1922.

My invention relates to carriages for flying machines, and its objects are to simplify the construction, to diminish to a minimum the resistance to air, and especially to provide a connection with the body by which the mounting is materially simplified and, if repairs become necessary, a quick exchanging of the carriage is rendered possible.

It has already been proposed to attach the wheels directly to the sides of the hull, all struts being avoided, or to rigid girders'secured laterally to the 'hull.

There have further become known carriages consisting of a transverse girder extending in the direction of the wheel axles and carrying the wheels which are secured to the ends of the irder, the girder being connected with the ying machine proper by means of a frame in such a manner that both its ends extend freely beyond the frame.

However, this arrangement involves the disadvantage that an exchange of the carriage requires much time and is difiicult, and further that it offers considerable resistance to the air. T

My invention obviates these drawbacks providing a carriage consisting of a T-sha-ped structure and havin the wheels attached to the ends of the rigid transverse girder, whereas the vertical arm, which is rigid alsoextends into the hill or body and is fastened therein preferably between two structural members. The necessary shock-absorption is effected preferably by the wheels being attached, instead of to the transverse girder, to axles extending through it; These axles are articulated about in the. middle of the flying machine and are resiliently connected In the drawings affixed to this "specification and forming part thereof a flying ma-' chine embodying my invention is illustrated diagrammatically by way ofexample.

In the drawings v Figure 1 is a front view and Fi ure 2 a side-view.

. Re erring to the drawings, the carriage ehas the form of an inverted T.- av is the horizontal transverse girder, b the vertical girder.

wheel axles are resiliently connected with the girder a at f. The shock-absorbers are not shown.

The vertical girder Z) is fixed to the body 9 between the structural members h.

The lateral walls of the girder a are provided with recesses 2' permitting the axle d to oscillate.

I wish it to be understood that I do not desire to be limited to the exact details ,of construction shown and described, for ob vious modifications will obcur to a person skilled in the art.

I claim 1. A flying machine-carriage comprising a hull and two single rigid girders combined to form a structure resembling an inverted T, the vertical girder extending into said hull and wheels near the ends of the hori zontal girder.

2. A flying machine-carriage comprising rigid girders combined to form a structure resembling an inverted T, the vertical girder being fixed to the' flying machine, a wheel axle extending along the horizontal girder and wheels on said axle.

3. A flying machine-carriage comprising rigid girders combined to form a structure resembling an inverted T, the vertical girder being fixed to the flying machine, a wheel axle extending along thehorizontal girder an? articulated thereto and wheels on said ax e.

4. A- flying machine-carriage comprising rigid girders combined to form a structure resembling an inverted T, a hull and vertical structural members forming part of said hull, the vertical girder extending between and being fixed to said members, and wheels near the ends of the horizontal girder.

5. Flying machine comprising a hull, vertical structural members forming part of said hull, a rigid girder extending downwards between and fixed to said members, anotherrigid girder fixed in. horizontal. position tothe lpwer ends of said first-men tioned. girder substantially at right angles thereto, an axle extending through said horizontal girder and wheels connected with said axle. i

The wheels 0 are attached to axles (1D In testimony whereof I aflix my signature.

capable of oscillating about the point e. The
