Application filed August 15, 1913. Serial No. 784,848.
To all whom it may concern..-
Be it known that 1', KURT Sonun'rzn, a subject of the German. Emperor, and a resident of Pankow, Berlin, Germany, have invented certain new and useful Improvements in Devices for Preventing the Cap sizing of Floating Crafts, and Particularly of Flying-Boats, of which the following is a specification.
Various devices have been proposed to prevent the upsettin or capsizing of boats, one type of such devices comprising tubular ioats movably connected by arms with the boat hull so as to be capable of swinging relatively thereto. Normally, these floats lie against the sides of the hull, but in case the boat should upset, the floats are projected and form Outriggers to prevent the capsized boat from rolling. The amount of projection which these devices can be given is only slight, in view of the limited space available on the sides of the hull for receiving the rigid arms in their normal position, that is to say, when they are not in use. This defect is particularly noticeable when the device is employed to prevent the upsetting of hulls which on account of a strong tendency to capsize require Outriggers projecting to a considerable distance in order eflectively to counteract such tendency; this is the case, for instance, with flying boats. Aircrafts of the aeroplane type do notread ily admit of using outriggers with rigid arms, on account of the considerable overhang or projection required, and besides, these Outriggers have the drawback of great weight. According to my invention, these defects are avoided by constructing all portions of the Outriggers, of inflatable tubular material stifl'ened by internal pressure.
I am aware that inflatable floats have been proposed for use in connection with aeroplanes, but not as Outriggers with inflatable carrier arms. Outriggers embodying my invention are flexible in the (deflated) condition of non-use and may therefore be rolled together so as to take up very little room. According to another feature of my invention, these hollow outrigger arms are also used as conduits through which the medium under pressure is conveyed to the outrigger bodies or floats.
Figure l of the accompanying drawing is a plan view showing the hull of a flying boat provided with my improved outrigger arrangement, showing the same projected or extended for use, and Fig. 2 is a cross section taken on line Pi -2 of Fig. 1.
It will be understood that I have shown and described only a typical example of my invention, and that various modifications may be made without departing from the nature of my invention as set forth in the appended claims.
To the outside oi the hull A are secured flexible tubes or hose portions 6, the outer ends of which communicate with inflatable and collapsible hollow bodies or floats B, the longitudinal axes of said floats being parallel to the longitudinal axis of the hull A. The inner ends of all the flexible inflatable and collapsible tubes Z) are connected with flasks C located in the hull A and filled with a suitable medium under pressure, such as compressed air, carbonic acid gas, hydrogen, etc. ()f course, the tubular arms 7) and the floats B are made of suitable material to properly hold the medium used. The flasks C are of the well-known character, being provided with valves so that the pressure medium may be injected into the arms 7) and floats B whenever desired. Upon opening the flask valves, the compressed medium streaming into the tubular arms 7) will straighten and project them. Projecting the Outriggers into the operative position is accomplished very quickly, so that the device is ready for immediate use in an emergency. When not in use, the tubular arms 6 hang or lie loose at the outside of the hull A, or are rolled or coiled up against it. In rolling the arms, care should be taken not to form in them any kinks which might interfere with their inflation. In order to guard efllciently against a failure of the device to operate on account of the accidental formation of kinks, I provide a considerable number of flexible tubes or arms 2'), so that even in the event of one or more arms having kinks, a suflicient number of operative arms will remain to project the floats B and straighten out all the arms 6, thus at the same time removing the kinks from the arms which were temporarily inoperative.
I claim as my invention:
1. A device for preventing the capsizing of floating crafts, comprising floats and outrigger arms connected therewith, said floats and arms being hollow and made of flexible material admitting of their inflation.
2. The combination, with the hull, of tubular outrigger arms made of flexible material and connected with said hull, and hollow floats connected and communicating with the outer ends of said arms.
3. The combination, with the hull, of inflatable tubular outrigger arms having their inner ends connected with said hull, and floats secured to the outer ends of said arms.
4. The combination, With the hull, of hollow arms secured to the hull at their inner ends, and inflatable floats communicating with the outer ends of said arms.
5. The combination, with the hull, of hollow arms secured to the hull at their inner portions, inflatable floats communicating with the outer ends of said arms, and inflating means connected with the inner ends of said arms.
6. The combination, with the hull, of inflatable and collapsible arms connected with said hull, and floats at the outer ends of said arms.
7. The combination, with the hull, of inflatable and collapsible arms secured to said hull with their inner portions, inflatable and collapsible floats communicating with the outer ends of said arms, and inflating means connected with the inner ends of said arms.
In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
KURT SCHULTZE.
