BIPLANE RITE.

Specification of Lettdi'a Patent. I

Patented Apr. 2,1912;

Application filed September 16, 1911. Serial No. 649,689.

To all whom it may concern: s

Be it" known that I, OTTO BETH, a native of Germany, but a resident of the United States, residing at Lynbrook, in the county of Nassau and. State of New York, have invented new and useful Improvements in Biplane Kites, of which the following is a specification. i

This invention relates to biplane kites, and its object is to provide a novel string attachment or arrangement of controlling cord and branches whereby the kite may be kept at the right angle and prevented from tipping over in the air.

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to .plan view of the kite.-

the accompanying drawings, in which- Figure 1 is a bottom perspective viewof a kite embodying my invention. Fig. 2 is a side elevation of the same; Fig. .3 is a top Fig. 4 is a front elevation of the same.

The kite ,comprises a main frame 1, carrying fore and aft extensions or head and tail frames 2 and 3. The main frame alsocarries a pair of superposed supporting planes.

, 4 and 5 provided withrear stabilizing extensions 6. Supported by the head frame is a front stabilizing 'plane 7 and supported by the tail frame are superposed stabilizin planes 8 and 9 between. which is dispose apanel or vertical plane 10, operating to hold the kitevfrom lateral or sidewise motion fgainst side gusts of air. The parts of ramework are stayed by suitable braces 11. v

For controlling the kite a cord or string 12. is provided which extends upward between the sides of the head'frame at. a point in advance of the main frame. This cord.

is connected by branches 18'with the front corner portions 'o'fthe" head frame, and by branches 14 with the lower rear corners of the main frame. It is also connected by branches 15 with the upper front corners of the main frame and by branches 16 with the upper rear corners of said mainframe. By this construction and arrangement of the controlling cord and its branches, the parts of the kite structure are connected with the cord in such a manner as to balance its pull upon the different ortions of the body of the kite, whereby t e kite adapted to be controlled in an easy and effective manner and to be held at the ri ht angle against the pressure of the wind or/a supporting action, thus preventing the kite from tilting unduly in any direction ,and turning over in the air. A tail string 17 is provided for supportin a suitable tail balance and is connected wlth-the lower rear corner portions of the tail frame b branches 18. This construction provides or the equal transmission ofthe resistance of the tail balance to the tail portion of. the late, whereby further provision is made for maintaining the equilibrium of the kite.

Having thus described the invention, what I claim as new is:

A biplane kite including a. main frame carr ing superposed supporting surfaces, hea and tail frames carrying balancing surfaces, a controlling cord branches leading from the cord to the f the head frame, branches leading from the cord to the upper front and reafcornersofi, the main frame, and branches leading from the cord to the lower rear corners of the main frame.

In testimony whereof I aflixmy signature in presence of two witnesses.
