C. DORNIER GIANT FLYING BOAT Filed June 28, 1920 INVE NTOR:

Patented Sept. 8, 1925.

UNITED STATES CLAUDE DORN'IEB, OF FRIEDRICHSHAFEN, GERMANY.

GIANT FLYING BOAT.

Application filed June 28, 1920. Serial No. 392,561.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)

To all whom it may concern:

Be it known that I, CLAUDE DORNIER,

a citizen of the German Empire, residing at Friedrichshafen on the Bodensee, Ger- 5 many, have invented certain new and useful Improvements in Giant Flying Boats (for which I have filed application in Germany March 21, 1917), of which the following is a specification.

My invention refers to hydroaeroplanes and more especially to the arrangement of floats on the type called flying boats.

It is an object of my invention to provide flying boats with floats arranged in such manner that no detrimental strains of any kind are transmitted by the floats to the supporting plane framework and the air resistances is not increased. According to my invention lateral floats are hidden in indentures of the boats hull when not in use, and can be moved into working position by pushing or swinging them out laterally. These floats, can further be so designed as to serve as life boats.

The drawings attached to this specification and forming part thereof, illustrate a modification of a flying boat in accordance with my invention in a purely diagrammatical manner.

Fig. 1 is a front view of a giant hydroplane with the lateral floats in their working position, and

Fig. 2 a top view of the hull.

In the drawings, A is a supporting plane to which the boat-shaped hull O is attached by means of struts B. The hull C has two lateral indentures c in which are hidden two floats D. The indentures and the floats are formed in such a way that, when the floats D are in their respective positions of rest, their outer walls are flush with the hulls walls. For the purpose of moving them into working position, rails E are provided which can be pushed outwards from the hull. The floats D are attached to the ends of these rails and are further connected with the hull C by detachable ropes or poles F.

On the boat tilting sidewards, thereby causing the floats to touch the water, the floats will act towards increasing the lateral stability of the craft.

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

I claim:

In a flying boat in combination, a boatshaped hull, indentures in the side walls of said hull and boat-shaped floats fitting in said indentures and movably connected with said hull, said floats being adapted to serve as life-boats.

In testimony whereof I affix my signature.

CLAUDE DORNIER.
