AXLE FOE FLYING mao'nmns.

Application filed June i0, 1924. Serial no. 719,064.

' To allwhom it may concern:

Be it "known that I, HANNS KLEMM, a citizen of the State of Wurttemberg, Germany, residing at Sindelfingen, Bahnhofstrasse 38, Wurttemberg, Germany, have invented certain new and useful Improve- :ments in anAxle for Flying Machines, of

which the following is a specification.

It is, as is known, customary with motorcars, as well as with flying-machines, to arrange springs between the underframe or carriage and the body or hull in order to dampen the shocks arising when the machine starts and when it lands, and to prevent illlleiiiu from being transmitted to the body or The means employed hitherto for these vpurposes, i. e. rubber-butters, spiral-springs, flat springs, and the like, require special members for their connection with the hull,

such as struts, axles, staying or stiffening members, and the like, and these additional members frequently cause trouble on account of breaking or becoming disconnected.

Furthermore the desired simplification of the carriage must be kept within restricted limits, for the reason that said special members must themselves be provided with other special or additional means in order to obtain an aerodynamically favorable outline.

The object of the invention is to obviate the above-mentioned drawbacks, and I attain that object by so devising the axlesof the carriage of the flying-machine that they form springs having a stream-line crosssection and being shaped similarly to sup-v porting planes. I am aware of the fact that these features are singly known but my 'invention consists in a new combination thereof and one of the effects of this combination is an essential simplification ofthe carriage.

to the stream-,line-shaped cross-section of the springs the otherwise required lining-pieces or the like can be dispensedp with, and the connection between the carriage and the hull is far simpler.- Besides,

the total area of the supporting planes is plane formedw increased by thesupporting by the spring owing to this special shape and arrangement, as is all more fully described, hereinafter. 1

My invention is illustrated diagrammatically and by way of example in the'accom panying drawing in which Figure 1 a front view of a carriage (of a flying machine) constructed according to this invention, the hull being merely indicated by a few lines; Figure 2 is a plan of the left-hand part of Fig. 1, and Figs. 3, 4 and 5 are sections through a set of springs in the planes aa, bb, and cc respectively of Fig. 1.

The axle a of the carriage of the flying machine is composed of a plurality of superposed flat springs, the shape of which appears from Fig. 2. The running-wheels b are, in the example shown, attached to the lowermost, i. e. longest and broadest, of said springs. The hull a is connected with the axle a, that-is with the superposed springs, in any known manner. v

The springs are so shaped as to form a kind of supporting plane, and are, theresection of the superposed springs form stream-lines. It is also obvious that the carriage of the flying machine is greatly simplified by the composition of the axle of the running-wheel of superposed flat springs having, in their entirety, a section corresponding to the shape of a stream-line- Such an axle offers but slight resistanceto its passage through the air and can be used as a means to increase the buoyancy.

The axle a, or the set of springs respectively, may consist of any appropriate kind of wood, such as, ash-tree wood, and the wheel-base may be increased without an mcrease of the weight, the supporting-base being then correspondingly larger and the clasticity greater.

I claim; a p

' 1. In a flying-machine, in combination: a hull and a carriage comprising wheels and superposed springs, the combined sections of which parallel to the longitudinal axis of the hull form an additional supporting sections of said springs being shaped ac- -cording to stream lines. 3. In a flying machine, an axle composed of laminated springs, the -width"-of said springsdiminishing toward the top thereof, and the lowermost of said springs being of g mowoo a suficient Width to form an addiitionol In testimony whereof I afix my signature supporting ia-me, V in presence of two Witnesses.

4.- In a flying machine, an axle composed of laminated springs made of an appropriate HANNS KLJEMM. 5 kind of Wood, the combined cross sections Witnesses;

of said springs being shaped according to VmToR BENM,

stream lines. Frau M. .Womi.
